A car travels

Alborosie

A car travels - 1/6.
in 3/5 of an hour -
60 / 5 - 12 x 3 = 36.
so in 36 minutes.

4/5 = 36+12 = 48 minutes.
2/6.

5/5 (full hour ) = 60 minutes.
3/6.

Car can travel - 3/6.

Connie's dog fido weighs 35 pounds. Her vet placed fido on a diet. What inequality can you write to find the average number of p

lawyer [7]

Fido's dog must lose 1.17 pounds each month to reach healthier weight.

Step-by-step explanation:

Given,

Weight of fido's dog = 35 pounds

Time period = 6 months

Goal weight to reach = 28 or less pounds

Let,

m be the weight to be lose each month.

Weight of dog - Time period * Weight to lose each month ≤ Goal weight

$35-6m\leq 28\\-6m\leq 28-35\\-6m\leq -7$

Dividing both sides by -6

$\frac{-6m}{-6}\leq \frac{-7}{-6}\\\\m\leq 1.17$

Fido's dog must lose 1.17 pounds each month to reach healthier weight.

Answer: 500cm squared

Step-by-step explanation:

To figure out the area, here are the steps

First, seperate the parallelogram into 2 triangles and a rectangle.

Secondly, we see it has figured out the area of the triangle which is 25, so we can assume that the other triangle is also 25. So the area of the two triangles are 25 + 25 = 50

Then, if we look at what it has labeled, we would know that the length of the parallelogram is 50, BUT this 50 contains ONE length of the triangle, which means to get the actual length of the rectangle, we must subtract a length of a triangle from 50.

That's 50 - 5 = 45. Therefore the area of the rectangle is (length times width) 45 ✕ width = the area of the rectangle.

Now we realize that we don't know the width of the rectangle, we can figure that out by back-tracking from the area of the triangle.

We know that area of a triangle is length times height divided by 2, so 25 ✕ 2 divided by legth would get us the height of the triangle. 25 ✕ 2 ÷ 5 = 10

Now we can figure out the area of the rectangle. 45 ✕ 10 = 450

Add the rectangle and the triangles together, you get -- 450 + 50 = 500 (cm squared）
