Answer:

135 ft^2 (first answer choice)

Step-by-step explanation:

Convert the length of the 7 yd base to feet:  21 ft.

Then the average length of the trapezoid is (15 ft + 21 ft)/2 = 36/2 ft = 18 ft.

The area of the trapezoid is then (average length)(height), or

A = (18 ft)(7.5 ft) = 135 ft^2 (first answer choice)

Answer:

82.5 ft²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h (b₁ + b₂)

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 7.5, b₁ = 7 and b₂ = 15 , then

A = \frac{1}{2} × 7.5 × (7 + 15) = 0.5 × 7.5 × 22 = 82.5 ft²

G(x) = 8x - 9 for g(x) = 23
aleksklad [387]
23=8x-9 It’s says g(x)=23 so put 23 where
+9 +9. The g(x) is on the equation.
First, add the 9
32=8x
/8 /8. Then, divide by 8.

4=x. And this should be your answer

Hope this helps! :)

If i was born in 2002 how old will i be in 2130
VMariaS [17]
To find that, we have to find the difference of 2130 and 2002, which is
2130-2002=128. We use subtraction due to that we start in 2002 but end in 2130, and therefore find the difference

Write 4,706 × 10 11 in standard notation
aleksandrvk [35]

I am guessing that is 1011? Just to be safe, I will do 4706*10 and 4706*1011.


4706*10: So, 4,706 times 10 is 47060

4706*1011: 4,706 times 1011 is 4757766

Standard notation is the normal way of writing numbers. So the answers I wrote are all in Standard notation.

V5. Suppose you invest $5,000 at 9% interest, compounded annually, for 10 years. Determine the future value of your investment,
Elanso [62]

Answer: $11836.8

Step-by-step explanation:

Given. That :

Amount invested = $5000

Interest rate = 9% = 0.09

Period = 10 years, compounded annually

Using the compound interest formula :

A = p(1 + r/n)^nt

A = final amount

P = principal or invested amount

r = rate of interest

n = number of times interest Is applied per period

t = period

A = 5000(1 + 0.09/1)^(1*10)

A = 5000(1.09)^10

A = 5000 * 2.36736367459211723401

A = 11836.81837296058617005

= $11836.8

Rewrite the expression using only positive integer exponents.
Andrews [41]

Answer:

So we got:

\left(m^{\frac{2}{3}}n^{\frac{-1}{3}}\right)^6

m^4\left(n^{\frac{-1}{3}}\right)^6\\

More attention for (n^{\frac{-1}{3}}\right))^6\\

n^{-2}

\frac{1}{n^2}

Join:

m^4\frac{1}{n^2}

\frac{1\cdot \:m^4}{n^2}\\\frac{m^4}{n^2}

Therefore, the answer is \frac{m^4}{n^2} , letter A
