Answer: 18 CM

Step-by-step explanation:

Since there are 4 sides to a rectangle, and 2 of them are lengths, we can multiply 24 by 2, which results in 48, and subtract it from the overall perimeter, which results in 36. Since the width is 2 sides, we can divide 36 by 2, which results in 18.

300 is 100% of what number?

laiz [17]

300/x=100/100
(300/x)*x=(100/100)*x - we multiply both sides of the equation by x
300=1*x - we divide both sides of the equation by (1) to get x
300/1=x
300=x
x=300

now we have:
100% of 300=300

The answer is 300

What is the equation of the function that is graphed as line a?

Andrei [34K]

Answer:

Step-by-step explanation:

We see that the line intersects the y-axis at -1. As a result, we need to choose an equation with -1, either B or C. We see that the different is the slope. For choice B, the slope is $\frac{1}{3}$ , meaning that every unit up equates to 3 blocks to the right. Counting along the line, we see that this is correct.
