maya drive 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?
8 hours
Step-by-step explanation:110 miles ................. 5 hours
176 miles ..................x hours
x = 176×5/110 = 880/110 = 8 hours
Answer:
maya drives 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?
We use the rule of three
110 miles -------------> 5 hours
176 miles ------------> ???
So (176 miles × 5 hours) /110 miles
We simplify by 《miles》 because it is in the numerator and the denominator
SO (176×5 hours )/110
= 880 hours / 110
= 8 hours
So she drives 176 miles in 8 hours.

A number is decreased by seven. Then, the new number is multiplied by 3 to get an answer of -9. What is the original number? A. -4 B. -30 C. 4 D. 30
Answer:
The answer is c
Step-by-step explanation:
You have to do everything backwards,
-9 divide it by 3 to get -3, then add seven to that answer
Answer:
C
Step-by-step explanation:
You can work backward to find out the answer!
Start with -9. Instead of multiplying by 3, you can divide.
-9/3 = -3
Now, instead of decreasing -3 by 7, increase by 7.
-3+7 = 4
You get 4, which is C!

the number of diagonals that can be drawn in a opolygon of n sides is 1/2n(n-1)-n. If 230 diagonsaals can be drawn how many sides does the polygon have'
Answer:
n = 20
Step-by-step explanation:
The number of diagonal that can be drawn in a polygon of n sides is given by :
[tex]D=\dfrac{n(n-3)}{2}[/tex]
If the number of diagonals are 230, then put D = 230 in above formula. So,
[tex]230=\dfrac{n(n-3)}{2}\\\\460=n^2-3n\\\\n^2-3n-460=0[/tex]
It is a quadratic equation, the value of n is equal to 20.
It means that for 230 diagonal, there are 20 sides of the polygon.
Hannah was adding 5 plus -4. When explaining her work she said that the sum is 9 because you add the numbers and take the sign of the larger number. In complete sentences explain what Hannah got wrong. What should the correct answer be?
Answer:
The sum is 1
Step-by-step explanation:
When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.
Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.
Select all that apply to the given number.

To determine the scale factor compare the ratio of corresponding coordinates, image to original, that is

We can calculate the depth d of snow, in centimeters, that accumulates in Harper's yard during the first h hours of a snowstorm using the equation d=5hd, equals, 5, h. How many hours does it take for 1 centimeter of snow to accumulate in Harper's yard? How many centimeters of snow accumulate per hour?
Answer:
a) 0.2 h
b) 5 cm
Step-by-step explanation:
The given equation is:
[tex] d = 5h [/tex] (1)
Where:
d: is the depth in centimeters
h: is the time in hours
a) The hours that takes for 1 cm of snow to accumulate in Harper's yard can be found by solving equation (1) for h and by entering d = 1 cm into the equation:
[tex]h = \frac{d}{5} = \frac{1}{5} = 0.2 h[/tex]
Hence, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.
b) The depth in centimeters of snow accumulate per hour is:
[tex] d = 5h = 5*1 = 5 cm [/tex]
Therefore, 5 cm of snow accumulates per hour.

Using the Exterior Angle Theorem, solve for the identified angle. WILL MAKE Brainliest!
Answer:
30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
150 = ?+120
Subtract 120 from each side
150-120 = ?
30 = ?
Answer:
[tex]\huge\boxed{<SUT = 30\ degrees}[/tex]
Step-by-step explanation:
According to exterior angle theorem:
The measure of the exterior angle is equal to the sum of non-adjacent interior angles.
So,
< VST = <STU + <SUT
150 = 120 + <SUT
<SUT = 150-120
<SUT = 30 degrees

Four plumbers estimated the length of the radius of a cylindrical pipe. The estimates made by the plumbers are listed. Which list shows these lengths in order from greatest to least?
Answer:
[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]
Step-by-step explanation:
To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.
[tex]\frac{3}{25}, \frac{\sqrt{3}}{11}, \frac{9}{100},\frac{\pi }{24}[/tex]
LCM of the denominators,
2 | 25 11 100 24
2 | 25 11 50 12
5 | 25 11 25 6
5 | 5 11 5 6
1 11 1 6
LCM = 2×2×5×5×6×11 = 6600
[tex]\frac{3}{25}=\frac{3}{25}\times \frac{264}{264}[/tex]
[tex]=\frac{792}{6600}[/tex]
[tex]\frac{\sqrt{3}}{11}=\frac{\sqrt{3} }{11}\times \frac{600}{600}[/tex]
[tex]=\frac{600\sqrt{3}}{6600}=\frac{1039}{6600}[/tex]
[tex]\frac{9}{100}=\frac{9}{100}\times \frac{66}{66}[/tex]
[tex]=\frac{594}{6600}[/tex]
[tex]\frac{\pi }{24}=\frac{\pi }{24}\times \frac{275}{275}[/tex]
[tex]=\frac{275\pi }{6600}[/tex]
[tex]=\frac{864}{6600}[/tex]
Now we can arrange these fractions in the order of greatest to least.
[tex]\frac{1039}{6600}>\frac{864}{6600}>\frac{792}{6600}>\frac{594}{6600}[/tex]
[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]
What is the value of p in the linear equation 24p +12 - 18p = 10 + 2p - 6 ? −4 −2 2 4
Answer:
SO we have to solve this equation:
24p + 12 - 18p = 10 + 2p - 6
First, we will operate what we have in both sides:
24p - 18p + 12 = 10 - 6 + 2p
6p + 12 = 4 + 2p
We substract 2p in both sides and 12 too.
6p + 12 - 2p - 12 = 4 + 2p - 2p - 12
4p = -8
Now, we divide both sides by 4
4p/4 = -8/4
p = -2
The value of p is -2.
The correct option is (B)
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
24p +12 - 18p = 10 + 2p - 6
Now, solving for p
6p + 12= 2p + 4
6p - 2p = 4 -12
4p = -8
p= -8/4
p= -2
Hence, the value of p is -2.

if this cylindrical vase were filled with water. approximately how much water would it contain? A. 63in^3 B. 126in^3 C. 251in^3 D. 503in^3
Answer:
126 in³
Step-by-step explanation:
Given a cylindrical vase having a diameter (d) of 4 in, and an height (h) of 10 in, the amount of water it would contain can be calculated using:
Volume of cylinder = πr²h
Where,
r = radius = ½ of d = ½*4 = 2 in
h = height = 10 in
Take π as 3.14
Plug in the values into the formula
Volume = 3.14*2²*10 = 3.14*4*10 = 125.6 ≈ 126 in³
The term "elevation" is often used to describe the height of a place (such as a city, a mountain, or a valley) compared to sea level. For example, the city of Houston, Texas has an elevation of 105 feet. The surface of the sea has an elevation of 0 feet. Some places are below sea level, so their elevations are negative values. Two towns have different elevations, but when the elevations are used as inputs of , they both produce an output of 25. Why do they produce the same output?
Answer:
obviously they will produce same output because the elevation of object and image will be same

what is the doors width in simplest form
Answer:
x + 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of rectangle = 3x + 6
Width of rectangle = 4x – 1
Width of door =..?
A careful observation of the diagram shows that the door is located along the length of rectangular room.
In a rectangle, two sides are equal. Therefore,
x + door + x = 3x + 6
Making door subject of the above formula, we have:
x + door + x = 3x + 6
door + x + x = 3x + 6
door + 2x = 3x + 6
Subtract 2x from both side
door + 2x – 2x = 3x + 6 – 2x
door = 3x – 2x + 6
door = x + 6
Therefore, the width of the door is x + 6

===============================================
Let a,b,c,d be scalars.
In general if v and w are two vectors such that
v = <a, b>
w = <c,d>
then the difference of the two vectors is
v - w = <a-c, b-d>
so we subtract the coordinates
-----------------
Using that idea for the given vectors leads to
v = <9, -1>
w = <-1, -6>
v - w = <9 - (-1), -1-(-6)>
v - w = <9+1, -1+6>
