Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The area of a trapezoid is equal to
![A=\frac{1}{2}[b_1+b_2]h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5Bb_1%2Bb_2%5Dh)
where
b_1 and b_2 are the length of the parallel bases
h is the height (perpendicular distance between the parallel bases)
we have
substitute
![A=\frac{1}{2}[210+480]320=110,400\ mi^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5B210%2B480%5D320%3D110%2C400%5C%20mi%5E2)
Answer:
= a^7
Step-by-step explanation:
Given in the question,
a^5 * a^4 / a²
To find,
show working
<h3>Explanation</h3>
As we know that to divide exponents (or powers) with the same base, we subtract the exponents. Division is the opposite of multiplication, so when multiplying the exponents (or powers) with the same base add the exponents.
<h3>Working</h3>
a^5 * a^4 / a²
= a^(5 + 4) / a² (Multiplying)
= a^9 / a²
= a^(9 - 2) (Dividing)
= a^7
<em>hence shown</em>
21 its 21 because it is 21
Answer:
12825$
Step-by-step explanation:
1 yard = 3 ft
we can convert each of the lengths from ft to yards
240 ft = 80 yards
285 ft = 95 yards
450 ft = 150 yards
150+150+95+80 = 475 yards
1 yard of fencing costs 27$ so we are going to multiply that by the total yards
475*27=12825$
