Answer:

perimeter above side length four times

Step-by-step explanation:

we know that

The perimeter of a square is equal to

P=4b

where

b is the length side of the square

Solve the formula by b

That means----> isolate the variable b

Divide by 4 both sides

b=\frac{P}{4}

we have

P=38\ in

substitute

b=\frac{38}{4}=9.5\ in

Rewrite the expression  b=\frac{P}{4}

\frac{P}{b}=4

so

perimeter above side length four times

I am Lyosha [343]
From an acceleration-time graph, you can work out the area under the graph to find the velocity. There are two triangles on the graph as shown below. The total area of the triangles are

\frac{(10)(10)}{2}+ \frac{(20)(20)}{2}=250 ft/sec^{2}

Hence, the distance is 250×30=7500 ft

rodikova [14]

Answer:

(a) 55.6%

(b) 45.0%

(c) 38.5%

(d) 27.1%

(e) 64

(f) 47

(g) The Lions

Step-by-step explanation:

(a) Free throw % for Lions is

\dfrac{10}{18}\times 100\% = 55.6\%

(b) Free throw % for Eagles is

\dfrac{9}{20}\times100\% = 45\%

(c) For the Lions, they attempted a total of 51 + 14 = 65 field goals and made 21 + 4 = 25.

Field goal % for Lions is

\dfrac{25}{65}\times100\% = 38.5\%

(d) For the Eagles, they attempted a total of 45 + 14 = 59 field goals and made 10 + 6 = 16.

Field goal % for Eagles is

\dfrac{16}{59}\times100\% = 27.1\%

(e) Total points by Lions = (10 × 1) + (21 × 2) + (4 × 3) = 10 + 42 + 12 = 64

(f) Total points by Eagles = (9 × 1) + (10 × 2) + (6 × 3) = 9 + 20 + 18 = 47

(g) The Lions won because they had more points.

Answer:

1961

Step-by-step explanation:

circumference = 2\pi R\\157 = 2\pi R\\157 = 2\pi* R\\R = 157 / 2\pi \\\\area = \pi R^{2} \\area = \pi* (157 / 2\pi)^{2} \\area = \frac{24649}{4\pi} \\area = 1961 \\

ok, I did smth wrong

I hope you can find error

What is the definition of a unit rate?
Arada [10]
When rates are expressed as a quantity of 1, such as 2 feet per second<span> or </span>5 miles per hour<span>, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.</span>
