1 ounce = 0,0625 pound = 1/16 pound

10-oz = 0,625 pounds = 1/16 * 10 = 10/16 = 5/8 pounds

3 * 5 (bags donated to the pantry) = 15
15 ÷ 5/8 = = 15 * 8/5 = 3 * 8 = 24

Answer: There are 24 10-oz bags needed to fit three 5-lb bags.

A student solved for the radius of a circle with a circumference of 12π Step 1: C = 2 pi r. Step 2: 12 pi = 2 pi r. Step 3: Star

Greeley [361]

Answer:

The student made a mistake in step 4

The length of the radius should be 6 cm

Step-by-step explanation:

Let us write each step to find the radius of a circle from its circumference

Step 1:

∵ C = 2πr

∵ C = 12π

Step 2:

Equate 12π by 2πr

∴ 12π = 2πr

Step 3:

Divide both sides by 2π

∵ $\frac{12\pi }{2\pi }=\frac{2\pi r}{2\pi }$

Step 4:

∴ 6 = r

∴ The radius of the circle is 6 cm

The student mad a mistake he divided the left hand side by 2π and the right hand side by 2 only he left π with r

Step 4:

∴ 6 = πr

So he divided both sides again by π

Step 5:

∵ $\frac{6}{\pi }=\frac{\pi r}{\pi }$

Step 7:

∴ $\frac{6}{\pi }$ = r

The student made a mistake in step 4

The length of the radius should be 6 cm

Step-by-step explanation:

The area of a triangle equals 1/2*base of triangle*height of triangle. Think about when you're finding the area of a square, you multiply the base times its height. A triangle is half of a square so then you just multiply it by 1/2.
