A traveler from Europe wants to
convert the distance 700 miles to
kilometers. If 1 mile equals
1.61 kilometers, what is the distance
between the two cities in kilometers?
Answer: 1,127 km.
Disclaimer: There are a plethora of ways to solve this problem, but I decided to utilize proportions to solve it, as I believe that it is the easiest method to solve these types of questions.
1. Set up your proportion
2. Set up a basic algebraic equation: 1x=700
In other words, what times 1 is 700?
Multiply 1*700, which is 700, and do the same for the bottom.
1.61*700= 1,127
3. The final answer is 1,127 kilometers. Please refer to the pictures attached for a more visual and thorough explanation. Cross mutiplying could also be used. Simply cross multiply in your proportion to get your answer.
Write the expression:
Four more than five times a numbern( use the litter n for the variable)
Answer:
5n+4
Step-by-step explanation:
Four more than 5 times a number (n)
So we get 5n+4
Answer:
5n+4
Step-by-step explanation:
As you have 4 more, you know you need to add four to n. Then, the expression asks 5 times n, leaving 5n+4.

What is the first step to solving 8=2/3x
Answer:
the first step is to divide two by three x
Answer:
x = 12
Step-by-step explanation:
Eliminating the fractional coefficient would be a great start:
8 = (2/3)x becomes 24 = 2x after multiplication of both sides by 3.
Then x = 12

Answer:
176 cm
Step-by-step explanation:
Area of a triangle = h b/2
8 * 11 ÷ 2 = 44 cm
Area of a rectangle = l * w
12 * 11 = 132 cm
Add both areas together
44 + 132 = 176 cm
A community is building a square park with sides that measure 150 meters. To separate the picnic
area from the play area, the park is split by a diagonal line from opposite corners. Determine the
approximate length of the diagonal line that splits the square. If necessary, round your answer to
the nearest meter.
Answer:
212 meters
Step-by-step explanation:
The diagonal of a square is the square root of 2 times the length of the square. This can be rewritten as the square root of (2*area)
2 * 22500 = 45000
The square root of 45000 is about 212.13, which would round down to 212 meters.
Harry bought a broken motor scooter, fixed it, and sold the scooter for $150. That was $25 less than 2 times the amount he paid for it. Which equation can be used to find, p, the amount of money Harry originally paid for the scooter?
Answer:
p/2 - 25 = 150
Step-by-step explanation:
I'll try my best.
$150 would be the initial value, so we would use that for the base.
$25 less means subtract 25 dollars in this context.
2 times means multiply by 2.
"$150 was $25 less than 2 times the amount he paid for it ([tex]p[/tex])."
[tex]\frac{p}{2} -25 = 150[/tex]
If you were to solve this:
[tex]\frac{p}{2} -25 = 150[/tex]
[tex]\frac{p}{2} =175[/tex]
[tex]p=350[/tex]
The answer I get from the equation would be $350.
If you input 350 into it:
[tex]\frac{(350)}{2} -25[/tex]
[tex]175 -25[/tex]
[tex]150[/tex]
Answer:
P = 150 ÷ 2 - 25 = p
Step-by-step explanation:
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.
Given: Harry bought a broken motor scooter, fixed it, and sold the scooter for $150. $25 less than 2 times the amount he paid for it.
To find: Which equation can be used to find, p, the amount of money Harry originally paid for the scooter?
Solution: It says; "That was $25 less than 2 times the amount he paid for it"
With that said, find the amount that is 2 times more than 150. To find that, the opposite of times is division, so divide 150 by 2
[tex]150[/tex] ÷ [tex]2 =[/tex] [tex]75[/tex]
Now that has been found, the next thing to find is $25 less, less means subtract. To calculate the amount Harry originally paid for the scooter, subtract 25 from 75
[tex]75 - 25 = 50[/tex]
Therefore, the amount of money Harry originally paid for the scooter is $50
Hence, the equation can now be found as; P = 150 ÷ 2 - 25 = p
Circumference and Area questions look at the picture
Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².
π≈3.14
A. C=πd
Simply plug in the numbers into the formula.
Diameter=Radius*2
17*2=34
C=34(π)
B. (π)(5²)
Plug in the numbers into the formula. Remember that half of the diameter is the radius.
C. (π)(4.5)
There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.
The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.
D. (π)(6.5²)
Remember that the formula for calculating the area of a circle is πr².
Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.
(π)(6.5²)
Therefore, the last answer choice is the correct answer.
if a=8 8=b what does b equal?
why does it equal that?
Answer:
B equals 8
Step-by-step explanation:
Because it says so.
Answer:
a=b
Step-by-step explanation:
using the substitution property of equality, since both a and b equal 8 you can determine that they are equal to each other
Find a rational function that satisfies the given conditions. Answers may vary, but try to give the simplest answer possible:
Vertical asymptotes x = -4, x = 5;
x-intercept (-2, 0)
Answer:
[tex] \frac{x + 2}{ {x}^{2} - x - 20 } [/tex]
Step-by-step explanation:
Since the roots are -4 and 5, we can write that as
[tex](x + 4)(x - 5)[/tex]
Apply foil method to find our denominator.
We get
[tex] {x}^{2} - x - 20[/tex]
So that our denominator.
Since our denomiater gives us interger asymptote, our degree in our numerator must be 1 so the answer has to be a single interger or a single term.
Since our x intercepts is -2, we use
[tex](x + 2)[/tex]
So our rational denomiater is
[tex] \frac{x + 2}{ {x}^{2} - x - 20 } [/tex]

Point P is at (3,-3) it undergoes the transformation (x - 2, y + 3). Where is P' at?
Answer:
The coordinates of P' are [tex]P'(x,y) = (1, 0)[/tex].
Step-by-step explanation:
The coordinates of the point P' is determined by the following expression:
[tex]P'(x, y) = P(x,y) + T(x,y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Translated point.
[tex]T(x,y)[/tex] - Translation vector.
If we know that [tex]P(x,y) = (3, -3)[/tex] and [tex]T(x,y) = (-2, 3)[/tex], then the coordinates of point P':
[tex]P'(x,y) = (3, -3) + (-2, 3)[/tex]
[tex]P'(x,y) = (1, 0)[/tex]
The coordinates of P' are [tex]P'(x,y) = (1, 0)[/tex].

A rectangle has a height of w^2+3w+9w 2 +3w+9w, squared, plus, 3, w, plus, 9 and a width of w^2+2w 2 +2w, squared, plus, 2. Express the area of the entire rectangle.
Answer:
w⁴+5w³+17w²+24w +18
Step-by-step explanation:
Area of a rectangle = length * width
Given
Length = w²+3w+9
width = w²+2w+2
Area of the rectangle = (w²+3w+9)(w²+2w+2)
Area of the rectangle = w²(w²) + 2w(w²) + 2w² + 3w(w²) + 3w(2w) + 2(3w)+9w²+9(2w)+9(2)
Area of the rectangle = w^4+2w^3+2w²+3w^3+6w^2+6w+9w²+18w+18
Collect the like terms;
Area of the rectangle = w^4+2w^3+3w^3+2w²+6w²+9w²+6w+18w+18
Area of the rectangle = w⁴+5w³+17w²+24w +18
Hence the area of the entire triangle is w⁴+5w³+17w²+24w +18

Answer:
Slope = -⁵/3
Step-by-step explanation:
See the attachment below. In the attachment, the green line represents the the rise while the red line represents the run of the line.
The slope = rise/run
Rise = 5
Run = 3
Slope = -(5/3)
Slope = -⁵/3 (the slope would be negative because the line slants downwards from your left to the right)

Point B is tangent to the circle so the angle ABC would be 90 degrees.
John and Shawn are racing to see who can get his community service hours for scouting completed first. John, who has already completed 40 hours, plans to volunteer for 5 hours per week going forward. Shawn hasn't started yet, but plans to dedicate 15 hours per week to his volunteer project from now on. Before too long, the boys will be tied, with the same number of volunteer hours. How long will that take?
Answer:
John and Shawn spent the same number of hours after [tex]4[/tex] weeks.
Step-by-step explanation:
Number of hours already completed by John to his volunteer project [tex]=40[/tex] hours
Number of hours spent by John each week to his volunteer project [tex]=5[/tex] hours
Number of hours spent by Shawn each week to his volunteer project [tex]=15[/tex] hours
Suppose John and Shawn spent the same number of hours after [tex]x[/tex] weeks.
Therefore,
[tex]40+5x=15x[/tex]
[tex]40=15x-5x\\40=10x[/tex]
[tex]x=4[/tex] weeks.
So,
John and Shawn spent the same number of hours after [tex]4[/tex] weeks.
HELP ME I WILL HIVE U 5 stars ON IF ITS RIGHT PLZZZ !!!!!!!
Answer:
40
Step-by-step explanation:
The two angles form a right angle
A right angle has a measure of 90 degrees meaning that the sum of the two angles is 90
a + 50 = 90
90 - 50 = 40
Thus, a = 40
missing angle is (40⁰) :)
