The answer is 290. First calculate the area of the rectangle part on the bottom. area=20*9=180 square yards. Then calculate the area of the triangle on the top. Base length is 20, while the height is 20-9=11, so the area is 20*11/2=110. 180+110=290 square yards in total.

Perform the indicated operations below and simplify ((a+b)/4) + ((2a-b)/5).

ArbitrLikvidat [17]

Answer:

$\frac{(a+b)}{4} +\frac{(2a-b)}{5}=\frac{13a}{20} +\frac{b}{20}$

Step-by-step explanation:

We have:

$\frac{(a+b)}{4} +\frac{(2a-b)}{5}$

We can use <em>common denominator</em>.

Observation:

If you have, $\frac{a}{b} +\frac{c}{d}=\frac{(a*d)+(c*b)}{b*d}$

Then,

$\frac{(a+b)}{4} +\frac{(2a-b)}{5}=\frac{5(a+b)+4(2a-b)}{4*5}$

Using <em>distributive property</em>:

Observation:

c(a+b)=ca+cb

$\frac{5(a+b)+4(2a-b)}{4*5}=\frac{5a+5b+8a-4b}{20}=\frac{(5a+8a)+(5b-4b)}{20}$

Finally,

$\frac{(5a+8a)+(5b-4b)}{20} =\frac{13a+b}{20}=\frac{13a}{20} +\frac{b}{20}$

The answer then is:

$\frac{(a+b)}{4} +\frac{(2a-b)}{5}=\frac{13a}{20} +\frac{b}{20}$

Write a rule for the nth term of the geometric sequence:<br> a3=54, a6=1458

Shalnov [3]

Answer:

tn = -1350 + 468n

Step-by-step explanation:

First, we need to find the difference.

1458 - 54 / 6 - 3

= 468

Now we need to find the first term.

t3 = t1 + (n - 1) (d)

54 = t1 + (3 - 1)(468)

54 = t1 + (2)(468)

54 = t1 + 936

-882 = t1

The rule is:

tn = -882 + (n-1) (468)

tn = -882 + 468n - 468

tn = -1350 + 468n
