Ann [662]

Answer:

5 bags

Step-by-step explanation:

Given Marianne buys 16 bags of potting soil which come in 5/8 pound bags

The above provides 10pounds of potting soil already

Now her father says he needs 13 pounds So Marianne should get an extra of 13 - 10 =3 pounds of potting soil

We know that 1 bag contains 5/8 pounds of potting soil

x bags contain 3 pounds of potting soil

On cross multiplication we get

$\frac{5x}{8}=3$

x = $\frac{24}{5}$

since x is an integer x = 5 bags

Note that an extra amount of soil will be remained unused

What is the approximate area of the shaded sector in the circle shown below?

scZoUnD [109]

The diameter of the circle is 5.4 cm. The shaded area is 180 degrees, which is 1/2 of the circle.

Calculate the area of the full circle and divide by 2.
Area = PI x r^2
r = 5.4/2 = 2.7

Area = 3.14 x 2.7^2 = 22.90

Area of shaded part: 22.90 / 2 = 11.45 cm^2.

The answer is A.
