To solve this we must do some division and then some multiplication that is quite simple.

If 20 gallons in this new car is 440 miles.

And we need to find how far we can drive with 60 gallons

First we need to divide 60 by 20. With that we get 3

So we know 60 is 3 times of 20.

So with that information we know 20 gallons is still 440 miles.

So we take 3 x 440 since 60 is 3 x 20,
Which is 1320.

1320 being how far 60 gallons of gas can take you in miles

Hope this helps!

I believe that the ending answer you are looking for is 1320 miles with no gallons of gas because if you have 440 miles with 20 gallons of gas just do 440+440+440=1,320

Class a has x students and class b has y students. the average of class a is 85 and class b is 90. when the scores of class a an
Usimov [2.4K]
The total scores of the x students from class A can be calculated by multiplying x and the average which is equal to 85. That is 85x.

In similar manner, we are able to find for the total scores of the students from Class B. That would be, 90y.

Combining the scores, the new average then becomes 88. This is equal to,

                                 (85x + 90y) / (x + y ) = 88

Cross-multiplying,
                            85x + 90y = 88x + 88y

Combine all the x's and y's in each side of the equation.

                        85x - 88x = 88y - 90y

Combining terms,
                              -3x = -2y

The ratio is obtained through the step below,
                         -3x/-3y = -2y/-3y

                            x/y = 2/3

Thus, the ratio is 2/3.

Help! Please! Geometry!!
DiKsa [7]

9.

By the Segment Addition Postulate, SAP, we have

XY + YZ = XZ

so

YZ = XZ - XY = 5 cm - 2 cm = 3 cm

10.

M is the midpoint of XZ=5 cm so

XM = 5 cm / 2 =  2.5 cm

11.

XY + YM = XM

YM = XM - XY = 2.5 cm - 2 cm = 0.5 cm

12.

The midpoint is just the average of the coordinate A(-3,2), B(5,-4)

M = (A+B)/2 = \left( \dfrac{-3 + 5}{2}, \dfrac{2 + -4}{2} \right)

Answer: M is (1,-1)

You'll have to plot it yourself.

13.

For distances we calculate hypotenuses of a right triangle using the distnace formula or the Pythagorean Theorem.

AB^2 =(5 - -3)^2 + (-4 - 2)^2 = 8^2 + 6^2 = 100

Answer: AB=10

M is the midpoint of AB so

Answer: AM=MB=5

14.

B is the midpoint of AC.   We have A(-3,2), B(5,-4)

B = (A+C)/2

2B = A + C

C = 2B - A

C = ( 2(5) - -3, 2(-4) - 2 ) = (13, -10)

Check the midpoint of AC:

(A+C)/2 = ( (-3 + 13)/2, (2 + -10)/2 ) = (5, -4) = B, good

Answer: C is (13, -10)

Again I'll leave the plotting to you.

find the circumference and area of a circle with a diameter of 22 inches. leave your answers in the terms of pi
Roman55 [17]

Answer:

121π

Step-by-step explanation:

The formula for a circle is πr^2. But if given a diameter instead of radius, you simply divide by 2 because radius is half of a diameter.

Radius of this circle is 11 because you divide 22 by 2.

Then you follow the formula. 11^2=121.
