Answer:
It took 11.04 hours by Stephanie.
Step-by-step explanation:
Concept
distance = speed*time
time = distance/time
_________________________________
Given
for Steven
time = 10 hours
speed = 53 miles per hour
Distance for steven = 53*10 = 530 miles
_____________________________________
Now ,
as Stephanie also traveled the same distance as steven
Distance = 530 miles
speed = 48 miles per hour
time = 530/48 hour = 11.04 hours
Thus, It took 11.04 hours by Stephanie.
In other way
since distance traveled by Steven and Stephanie are same
let time taken by Stephanie be x hours
Distance traveled by steven = Distance traveled by Stephanie
53*10 = 48*x
x = 530/48 = 11.04 hours
equation = 53*10 = 48*x

Answer:
It looks like the number line is going by 2's. So I would say the answer is 20.
Hope this helps!
Answer: 20
Step-by-step explanation:
Assuming for every line you go up you increase the by 2.
So if you have 8 you skip a line and you end up at 12 the next line the line in between those 2 numbers should be 10. Leaving you with a sequence of numbers and if you keep going along 12, 14, 16, 18, you arrive at 20.
Mitch wants to buy a poster to put on the wall between his bathroom door and closet door. There is exactly 22.25 inches of space between the doors. What could be the width of the poster?
Answer:
22.25 inches
Step-by-step explanation:
Since in the question it is mentioned that the mitch wants to buy a poster and wants to put on a wall that is between his door of the bathroom and the closet door
Also the space between these two doors is 22.25 inches
So based on the above information, the width of the poster should be equivalent to the given space i.e. 22.25 inches and the same is to be considered
Answer:
Mitch wants to buy a poster to put on the wall between his bathroom door and closet door. There is exactly 22.25 inches of space between the doors. What could be the width of the poster? (The poster needs to fit on the wall, so it needs to be smaller or equal to the width between the doors
Step-by-step explanation:
The population of algae in an
experiment has been increasing by 40% each day. If there were 20 algae at the beginning of the experiment, predict the number of algae in 7 days.
First, complete the equation:
Future Amount = [?](1+[]0
The equation is y = 20(1.40)^x
where x is the number of days and y is the future amount after x days go by
The 1.40 is from the fact that 1+r = 1+0.40 = 1.40, where r is the decimal form of 40%, so r = 0.40
-----------------------------
Plug in x = 7 to get
y = 20(1.40)^x
y = 20(1.40)^7
y = 210.827008
y = 211
We round to the nearest whole number since it doesn't make much sense to have a fractional portion of an algae. After 7 days, there are about 211 algae.
A restaurant chef made 1 1/4 pints of mushroom soup. Each bowl of soup holds 5/8 of a pint.
How many bowls of soup will the chef be able to fill?
Answer:
2 bowls of soup
Step-by-step explanation:
1. Make 1 1/4 an improper fraction
1 1/4 = 5/4
2. Then divide 5/4 by 5/8 (KCF - Keep the 5/4 - Change the division sign to multiplication - 'Flip' 5/8 to 8/5)
5/4 x 8/5 = 40/20
3. Simplify the fraction (divide the numerator and denominator by 20)
40/20 = 2
4. Final answer:
2 (bowls of soup)

cual es el resultado de (7.006×10⁴¹)×(5.09×10²²)
Answer:
El resultado de (7.006×10⁴¹)×(5.09×10²²)=3.566054*10⁶⁴
Step-by-step explanation:
La notación científica es una manera rápida de representar un número utilizando potencias de base diez.
Los números se escriben como:
a*10ⁿ
donde:
a es un número real mayor o igual que 1 y menor que 10.n es un número entero, que recibe el nombre de exponente u orden de magnitud. Representa el número de veces que se desplaza la coma. Siempre es un número entero, positivo si se desplaza a la izquierda, negativo si se desplaza a la derecha.Para realizar la multiplicación con notación científica, debes multiplicar las magnitudes afectadas por las potencias de 10 y, por separado, multiplicar las potencias de 10, recordando la propiedad:
Si dos bases son iguales (el mismo número o variable), y son los factores de una multiplicación, ambas bases quedan en una sola y sus exponentes son sumados: xᵃ*xᵇ= xᵃ⁺ᵇEn este caso:
(7.006×10⁴¹)×(5.09×10²²)=(7.006*5.09)*(10⁴¹*10²²)=35.66054*10⁴¹⁺²²= 35.66054*10⁶³
Siguiendo el formato a*10ⁿ, debes ajustar el valor de la base a de manera que sea un número real mayor que 1 y menor que 10. Entonces, se mueve la coma decimal hacia la izquierda tantos espacios hasta llegar a la derecha del primer dígito. Y se escribe la base 10, al cual el exponente se suma la cantidad de espacios que se mueve la coma, que es un número positivo porque la coma se desplaza a la izquierda.
Entonces 35.66054*10⁶³= 3.566054*10⁶⁴
El resultado de (7.006×10⁴¹)×(5.09×10²²)=3.566054*10⁶⁴

3p + 4r = q solve for p
Answer:
[tex] p = \dfrac{q - 4r}{3} [/tex]
Step-by-step explanation:
3p + 4r = q
3p = q - 4r
[tex] p = \dfrac{q - 4r}{3} [/tex]
Answer:
[tex]p=\frac{q}{3} - \frac{4}{3}r[/tex]
Step-by-step explanation:
If we want to solve for p, our ultimate goal is to isolate it one one side of the equation.
Given [tex]3p + 4r = q[/tex], we can do a few actions on it to isolate the variable.
Divide both sides by 3:
[tex]p + \frac{4}{3}r = \frac{q}{3}[/tex]
Subtract [tex]\frac{4}{3} r[/tex] from both sides:
[tex]p = \frac{q}{3} - \frac{4}{3}r[/tex]

divide 10kg in the ratio of 13 : 7
Answer:
6.5 : 3.5
Step-by-step explanation:
So to do this sum;
First, add both 13 and 7 which is 20
Then, 13/20 *10 = 6.5
and 7/20 *10 = 3.5
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Equal quotients correspond to equal ratios.
Select all the ways the rectangle could have been rotated to get from Frame 1 to Frame 2. 40 degrees clockwise 40 degrees counterclockwise 90 degrees clockwise 90 degrees counterclockwise 140 degrees clockwise 140 degrees counterclockwise Lesson 3
Answer:
40 degrees clockwise
140 degrees counterclockwise
Step-by-step explanation:
The rectangle is rotated in Figure B. The angle of rotation is 40 degrees. If we rotate a rectangle at an angle of 40 degrees clockwise then wit will be at the position as shown in figure B. The 90 degrees angle is perpendicular angle. Rectangle will not reach the desired position. If we rotate the rectangle at 140 degrees counterclockwise this will be the figure B representation. The rotation to 90 degree counterclockwise is either not suitable for the desired rectangle position.

A. 5= -2(x- 1)
B. 5 = -2x+2
1) How can we get Equation B from Equation A ?
Choose 1 answer:
A)Rewrite one side (or both by combining like terms
B)Rewrite one side or both using the distributive property
C)Multiply divide both sides by the same non-zero constant
D)Multiply divide both sides by the same variable expression
Answer:
[tex]\Large \boxed{\mathrm{B}}[/tex]
Step-by-step explanation:
[tex]\sf 5 = -2(x - 1)[/tex]
Applying the distributive property.
We distribute the -2 to the terms in the brackets on the right side of the equation to get Equation B.
[tex]\sf 5 = -2(x) -2(-1)[/tex]
[tex]\sf 5 = -2x + 2[/tex]
To get Equation B from Equation A, we rewrite one side or both using the distributive property.
why are greek letters used in math and their origin and reasons
Answer:
Because European mathematics is very heavily rooted in the mathematics of ancient Greece, and due to the need for many symbols to represent constants, variables, functions and other mathematical objects, mathematicians frequently use letters from the Greek alphabet in their work.
Please show work and help me understand this multi-step equation.
Answer:
The correct answer is a = 17/9.
Step-by-step explanation:
To begin this problem, we should use the distributive property on the left side of the equation to get rid of the parentheses. This means that we can multiply each term inside the parentheses by the coefficient outside the parentheses. This is modeled below:
3a - 2 = 3/4a + 2 1/4
Next, we should change the mixed number into an improper fraction so that it is easier to work with.
3a - 2 = 3/4a + 9/4
Now, we can multiply both sides of the equation by 4. This is not a required step, but it will get rid of the fractions on the right side of the equation, so we only have to work in full numbers.
12a - 8 = 3a + 9
The next step is to subtract 3a from both sides and add 8 to both sides to separate the variable and constant terms.
12a - 3a - 8 + 8 = 3a - 3a + 9 + 8
9a = 17
Next, we can divide both sides by 9 to get our variable a alone on the left side of the equation.
a = 17/9
Therefore, the correct answer is a = 17/9.
The average price of gasoline in Paris, France, is 1.91 euros per liter. If there are 3.785 liters in one gallon, and the exchange rate is 1.203 euros for one dollar, what is the price of gas in dollars per gallon for gasoline in Paris?
The price of gasoline in Paris is $.61/gallon
The price of gasoline in Paris is $2.38/gallon
The price of gasoline in Paris is $6.00/gallon
Answer:
The price of gasoline in Paris is $6.00/gallon
Step-by-step explanation:
We are asked to find the price of gas in dollars per gallon for gasoline in Paris.
Step 1
We are told in the question that: the average price of gasoline in Paris, France, is 1.91 euros per liter.
Also we are told that, the exchange rate is 1.203 euros for one dollar
We convert the Euros to dollars
If, 1.203 euros = 1 dollar
1.91 euros = x dollars
We Cross Multiply
1.203 euros × x dollars = 1.91 euros × 1 dollar
x dollars = 1.91 euros × 1 dollar/ 1.203 euros
x dollars = 1.5876974231 dollars
Therefore, 1.203 euros = Approximately 1.59 dollars.
Hence, the price of gasoline in Paris, France is 1.59 dollars per liter.
Step 2
We convert the from liter to gallon
In the question, we are told that:
If there are 3.785 liters in one gallon
Therefore, if
1 liter of gasoline = 1.59 dollars
3.785 liters of gasoline =
Cross Multiply
= 3.785 liters × 1.59
= 6.01815 dollars.
Approximately to the nearest whole number = 6.00 dollars.
Since 3.785 liters of gasoline = 1 gallon of gasoline, therefore, the price of gas in dollars per gallon for gasoline in Paris is $6.00/gallon

Solve the equation. | 3k-2 | = 2| k+2 |
Answer:
[tex]-2/5 \text{ and } 6[/tex]
Step-by-step explanation:
So we have the equation:
[tex]|3k-2|=2|k+2|[/tex]
First, distribute the 2 into the absolute value:
[tex]|3k-2|=|2k+4|[/tex]
Definition of absolute value:
[tex]3k-2=(2k+4) \text{ or } 3k-2=-(2k+4)[/tex]
Left:
[tex]3k-2=2k+4[/tex]
Subtract 2k from both sides:
[tex]k-2=4[/tex]
Add 2 to both sides:
[tex]k=6[/tex]
Right:
[tex]3k-2=-(2k+4)[/tex]
Distribute the negative:
[tex]3k-2=-2k-4[/tex]
Add 2k to both sides:
[tex]5k-2=-4[/tex]
Add 2:
[tex]5k=-2[/tex]
Divide by 5:
[tex]k=-2/5[/tex]
So, our solutions are:
[tex]-2/5 \text{ and } 6[/tex]

In a certain county, the number of charter schools is 6 less than twice the number of alternative schools. We know that there are 52 charter schools in the county. How many alternative schools are in the county?
Answer:
29
Step-by-step explanation:
Answer:
29
Step-by-step explanation:
So, 52 charter schools and the number is 6 less than the alternative schools doubled. In order to find the number of alternative schools, we need to reverse the equation. 52+6=58. That means 58 is twice the amount of alternative schools. 58/2 equals 29, therefore the answer is 29

Option (D)
Step-by-step explanation:
All rational and irrational numbers are real numbers.
{-2, -1, -1.8, 0, 1, 2.......}
Numbers written in the form of [tex]\frac{p}{q}[/tex] are rational numbers. They are the part of irrational numbers.
{-2.5, -2, -1, 0, 1, 2.....}
Whole numbers with negative or positive notation are integers.
{-3, -2, -1, 0, 1, 2, 3, 4......}
Positive integers are the whole numbers (including zero).
{0, 1, 2, 3, 4, .......}
All whole numbers excluding zero are the natural numbers.
{1, 2, 3, 4,........}
Irrational numbers are the part of real numbers written in the form of [tex]\frac{p}{q}[/tex].
{[tex]\sqrt{2},\sqrt{5},\pi, \sqrt{10}[/tex]}
Therefore, [tex]\sqrt{8}[/tex] comes under Irrational numbers.

Taking the square root of a number is the *blank * Of squaring a number
Answer:
Opposite
Step-by-step explanation:
They are complete opposites:
When you take the square root of a number, you are taking the number to the 1/2 power. For example, the square root of 9 is 3.
When you square a number, you multiply it by itself. For example, 3 squared is 9.
So, these are opposites because when doing these operations to the same number, the products will be "opposites" of each other, like the examples above.
Given: A = {a, e, i, o, u}, B = {a, l, g, e, b, r}, C = {m, y, t, h}, A ∩ C is m, a, e, i, o, u, t, h the empty set i a, e, i, o, u, y
Answer:
the Empty set
Step-by-step explanation:
Recall that the intersection of two sets is another set that contains the elements common to both of the intersected sets.
Since sets A and C have NO element in common, then the answer is:
that the intersecting set is: the Empty set.
Answer:
the empty set
Step-by-step explanation:
this simbol ∩ is the intersection and it works as follows
[tex]X={1,2,3}\\\\Y={2,5,6,3}\\\\[/tex]
and X∩Y={2, 3}
because 2 and 3 are the only ones that are in both sets
so we have
A={a, e, i, o, u}
B={a, l, g, e, b, r}
C={m, y, t, h}
A∩C= the empty set
because A and C don't have any common subset
