Answer: 113.0 ft (bottom right corner)

=====================================

Explanation:

The triangle has a horizontal leg of 220 ft and a vertical leg of x ft. We'll use the tangent rule to connect the opposite side and adjacent side

opposite side = x
adjacent side = 220
this is with the reference angle shown in the diagram

So,
tan(angle) = opposite/adjacent
tan(26) = x/220
220*tan(26) = x
x = 220*tan(26)
x = 107.301169 ... see note below
x = 107.3

Now that we know the approximate value of x, we add on 5.7 to get
x+5.7 = 107.3+5.7 = 113.0

note: make sure your calculator is in degree mode. The value is approximate to 6 decimal places

Find the 4th term of the expansion of (2a - b)^7.

ankoles [38]

Answer:

-560a^4b^3

Step-by-step explanation:

Given:

(2a - b)^7

By using Binomial theorem:

128a^7 - 448a^6b + 672a^5b^2 - 560a^4b^3 + 280a^3b^4 - 84a^2b^5 + 14ab^6-b^7

Here the fourth term is -560a^4b^3 !

Salama makes fruit baskets with oranges and bananas. She uses between 8 and 16 oranges and bananas in a ratio of 3 oranges to 2

Studentka2010 [4]

Answer: There are 6 oranges and 4 bananas and there are 9 oranges and 6 bananas.

In both the cases, the ratio will be 3:2.

Step-by-step explanation:

Since we have given that

Salama makes fruit baskets with oranges and bananas.

Ratio of oranges to bananas is 3:2.

And she uses between 8 and 16 oranges and bananas.

We only take those number which is multiple of 5 between 8 and 16,

i.e. 10 and 15.

1) Let the total number of oranges and bananas = 10

Then, number of oranges is given by

Number of bananas is given by

2) Let the total number of oranges and bananas = 15

Then, number of oranges is given by

Number of bananas is given by

Hence, there are 6 oranges and 4 bananas and there are 9 oranges and 6 bananas.

In both the cases, the ratio will be 3:2.

A vehicle purchased for $22400 depreciates at a constant rate of 9%.

Dennis_Churaev [7]

Answer:

$15 827

Step-by-step explanation:

The formula for the amount A of depreciation of an asset by an annual percentage rate is

A = V(1 - r)ⁿ

where

n = number of years

r = annual percentage rate

V = value

Data:

n = 13 yr

r = 9 %

V = $22 400

Calculations:

A = 22 400(1 - 0.09)¹³ =22 400(0.91)¹³ = 22 400 × 0.293 45 = $ 6573

So, the car lost $6573 in value because of depreciation.

Current value = 22 400 - 6573 = $15 827

The Martinez family walked three over five of a mile in three over eight of an hour. What is their unit rate in miles per hour?

Vikki [24]

Answer:

three-fifths over three-eights equals one and three-fifths miles per hour

Step-by-step explanation:

The martinez family walked three over five of a mile; this means they walked 3/5 of a mile.
They walked such distance in in three over eight of an hour, this means 3/8 of an hour.

To find the rate in miles per hour, we have to divide 3/5 divided 3/8.

$\frac{3}{5} /\frac{3}{8}$

TO make division of fraction, we must invert the second fraction and multiply them:

$\frac{3}{5} *\frac{8}{3} =\frac{8}{5}$

The ratio is 8/5 miles per hour. In the answer given it is expressed as a mixed numer 1 3/5 that is equal to 8/5.

To transform a fraction to a mixed number, you have to divide numerator by denominator. Explanation is in figure attached.
