Answer:

134.4 centimeters

Step-by-step explanation:

This question is asking us for a missing leg on the triangle, lets call it x. Using the Pythagorean theorem (a²+b²=c²), we can figure out what value is missing (either a or b, they are interchangeable).

replace the values in the equation.

83²+x²=158²

get rid of the exponents.

6,889+ x² = 24,964.

subtract 6,889 from 24,964.

x²=18,075.

find the square root on both sides of the equation.

x=134.4432966.

I am assuming you want this rounded to the nearest tenth.

134.4 is your answer.

You deposit $3000 into a bank account that pays 1.25% annual interest, compounded semi-annually. What is the final balance after
mojhsa [17]

Answer:

$3,153.32

Step-by-step explanation:

Given that

The deposited amount is $3,000

The annual interest rate is 1.25%

So, the semi-annual interest rate is 1.25% ÷2  = 0.625%

And, the time period = 4 × 2 = 8

We need to find out the final balance

So,

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $3,000 × (1 + 0.625%)^8

= $3,153.32

The largest  possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'

<h3>Scale drawing</h3>

Scale drawing involves drawing a drawing in a different size and dimension that is proportional to the original dimension

<h3>Dimensions</h3>

The dimensions of the design for the farm scene painting is given as:

12" \times 9"

The dimensions of the wall is given as:

24' \times 16'

Convert feet to inches

24' \times 16' = (24 \times 12") \times (16 \times 12")

24' \times 16' = (288") \times (192")

Divide the dimensions of the wall by the painting to get the scale ratios (k)

k = \frac{288}{12}

k = 24

Also, we have:

k =\frac{192}{9}

k =21.33

Remove decimal (do not approximate)

k =21

By comparison;

21 is less than 24

Multiply 21 by the dimensions of the painting

So, we have:

Length = 12 \times 21 = 252

Width = 9 \times 21 = 189

Hence, the largest  possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'
