Answer: 36.4 miles per gallon!

Step-by-step explanation: To get your answer....divide the y (miles driven) by x (gallons used). Each divided gives you the answer of 36.4 which is the constant of proportionality between the number of miles driven and the number of gallons used.

For example: 691.6 divided by 19= 36.4

                       1528.8 divided by 42=36.4

                        1638 divided by 45=36.4

9(2x + 15) = 45
Can you help me?

Answers

Answer:

= -5

Step-by-step explanation:

First you would use distributive property and multiply the 9 and 2 (18x) then 9 and 15 (135)
Now you have 18x+135=45 so you need to get X alone by using inverse operations and subtract 135-45 (90)
18x=90 now you divide 18 and 90 and your answer is x=5

The measure of an angle is 60.6°. What is the measure of its supplementary angle?

Answers

Answer:

119.4°

Answer:

119.4 and the little degree sign (119.4 degrees)

solve the equation to find the missing leg of the right triangle

x2+0.5 squared=1.3 squared

Answers

Answer:

1.2

Step-by-step explanation:

x2 is the missing leg so the formula to find the missing leg to a right triangle is

c squared- b squared=a squared which in this case would be

1.3 ^2 - 0.5^2 = x^2  ( ^ means squared)

1.69 - 0.25 = x^2

[tex]\sqrt{x}[/tex]1.44 = 1.2

1.2 = missing leg

Step-by-step explanation:

1) Cut Cylinder in half, perpendicular to the circle face. Effectively making a rectangle face. The Pencil diagnolly reaching from the top corner to the bottom corner act like a divider which splits the rectangle into 2 triangles. Which allows for us to use Pythagorem theorem.

pythagorean theorem: [tex]c^2=a^2+b^2}[/tex]

The Pencil is 17cms long. So [tex]17^{2}[/tex]=[tex]{a^2+b^2}[/tex]

the height is 15cms long. So [tex]17^{2}[/tex]=[tex]15^2+b^2}[/tex]

We need to Solve for B, so we will subtract A from C since C is the longest side on the Triangle.

289-225=[tex]\sqrt{64\\}[/tex] = 8

b=8

b is the diameter of the Cylinder

Since we need the Radius squared for Cylinder we divide the Diameter in half. 8/2=4

4X4=16

Next we wil figure out the Volume,

[tex]\pi *4^{2} *15[/tex]=753.982236862

the answer is 753.98

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is -2(4 - 3x) + (5x - 2)

We have to find the equivalent expression

x is the variable in the expression

Equivalent expressions are expressions that work the same even though they look different.

Let us apply distributive property

-8+6x+5x-2

Combine the like terms

11x-10

Hence, -8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)
