Answer:

137.5 in^2

Step-by-step explanation:

So, this is basically a rectangle and two right-sides triangles.

First the rectangle: Formula is A=wl

Replace the Values: A = 14*7 98 in^2

Then we solve for the two right-sides triangles.

A= 1 /2a h= 1 /4 b ^2 sin (2 θ )

Top trinangle= A = 25.5 in^2 (height 7 in base 7 in)

Bottom Trinagle A = 14 in^2 (height 7 in base 4 in)

Add results:

98+25.5+14 = 137.5 in^2

Kesia knows that 1/4=0.25. Explain how she could use this fact to determine the decimal equivalent of 5/8

STatiana [176]

She knows that
$0.25 = \frac{1}{4} = \frac{2}{8}$
$\frac{5}{8} = \frac{2}{8} + \frac{2}{8} + \frac{1}{8} = \\ 0.25 + 0.25 + \frac{0.25}{2} = \\ 0.25 + 0.25 + 0.125 = 0.625$

Katena32 [7]

Answer: 2.5 ounces/ pint

You can firstly turn your fractions into decimals 5/8 is equal to .625 and 1/4 is .25

Then you can divide .625 by .25 which is 2.5, So the unit rate is 2.5 ounces per pint.

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?

boyakko [2]

Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286

And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)
