Greg spent 6.4 hours working with his dad one Saturday. If his dad paid him$45.76, how much did Greg make per hour?

nordsb [41]

Answer:

$7.15

Step-by-step explanation:

The best way to solve this is by crossing out the data you don't need so you're left looking at the key pieces to put the equation together. If his dad paid him $45.76 for 6.4 hours, then all you need to do is divide 45.76 by 6.4. (Hint: Use a calculator, it makes it ten times faster than trying to write it out!)

45.76 ÷ 6.4 = 7.15

So Greg made $7.15 an hour working with his dad.

The combined area of two squares is 17 square meters. the size of the larger Square are four times as long as the size of the sm

7nadin3 [17]

we are given that ,

The combined area of two squares is 17 square meters.

Area of square= $(side)^2$

Let the side length of smaller square be x

The size of the larger Square are four times as long as the size of the smaller square

$Area \ of \ smaller \ square \ =x^2$

So Area of larger square= $4x^2$

The combined Area is 17 square meter.

$x^2+4x^2=17\\\\5x^2=17\\\\x=\sqrt{\frac{17}{5}}$

Hence the smaller square has the side length= $\sqrt{\frac{17}{5}}$

So the larger square has side length= $2\sqrt{\frac{17}{5}}$

yellow car = x

9x +x = 40

10x = 40

x = 40/10 =4

4 yellow cars

9*4 = 36 white cars
