Find: 1) the area of a circle of diamter 5 feet and radius 5/2 feet.
2) the area of a triangle with height 4 ft and base 6 ft.

Add these 2 results together: pi*(5/2)^2 + (1/2)(6)(4) ft

The trick here is to recognize basic shapes, find their areas separately and add the results.

A=$20.20/10gal=$2.02 per gal

B=$26.04/12gal=$2.17 per gal

C=$28.14/14gal=$2.01 per gal

D=$30.45/15gal=$2.03 per gal

So C is the cheapest per gallon.

Jackson and Jonah are both swimming. Jackson swims at 1350 meters per hour. Jonah swims at a speed of 1250 millimeters per secon

Vladimir [108]

For this question we will use the following relations.

100 centimeters=1 meter (or 1 centimeter= 0.01 meter)

10 millimeter=1 centimeter (or 1 mm=0.1 cm)

60 minutes = 1 hour (or 1 min= $\frac{1}{60}$ hour)

Now, Jackson's speed is 1350 meters per hour. This can be converted to cm per minute as follows:

$\frac{1350 m}{1 h}=\frac{1350\times 100 cm}{60 min}=2250 cm/min$ ...Equation 1

Likewise, Jonah's swim speed in cm/min can be calculated as:

$\frac{1250 mm}{1 s}=\frac{1250\times 0.1 cm}{\frac{1}{60}min } =\frac{125\times 60 cm}{1 min}=7500cm/min$ ...Equation 2

As we can see clearly after comparing Equation 1 and Equation 2, Jonah's swim speed of 7500 cm/min is faster than that of Jackson.

Thus, option B is correct.

Of the 21 children at a park, 5 of them are playing on the swings. What is the approximate

Bond [772]

The Answer Is B

Use proportions to find x% of the children playing on the swings.

$\frac{21}{100} = \frac{5}{x\%}$

$x = 23.80952380\%$

Meaning B is correct.
