Find the value of X. .
Sliva [168]

The value of x is 12. 94°

<h3>How to determine the angle</h3>

From the diagram shown, we can see that the two angles are on a straight line.

It is important to note that angles on a straight line sum up to 180 degrees

Hence, we have;

(11x- 15) + 5x - 12 = 180°

collect like terms

11x + 5x - 15 - 12 = 180

Add like terms

16x - 27 = 180

16x = 180 + 27

16x = 207

Make 'x' the subject of formula

x = 207/ 16

x = 12. 94°

Thus, the value of x is 12. 94°

Answer:

$ 8,695.35

Step-by-step explanation:

This is a compound interest question

Amount after t years = A = P(1 + r/n)^nt

Where P = Initial Amount saved

r = interest rate

t = time in years

n = compounding frequency

A = 10,000

r = 3.5 %

t = 21 - 17 = 4 years

n = Compounded monthly = 12

Step 1

Converting R percent to r a decimal

r = R/100 = 3.5%/100 = 0.035 per year.

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

Solving our equation:

P = 10000 / ( 1 + (0.035/12)^12 ×4 =

P = $8,695.35

The principal investment required to get a total amount, principal plus interest, of $10,000.00 from interest compounded monthly at a rate of 3.5% per year for 4 years is $8,695.35.

Answer:

Increase in the length of one side = 3.8 ft

Step-by-step explanation:

Yossi has garage whose area is 280 ft²

After rebuilt their is increment in area by 50%

New Area = 280 × 150% = 420 ft²

Also we know that Area of Square = (Length) × (Length)

⇒ Length of Newly built garage = √420 = 20.5 ft

and Length of Originally garage = √280 = 16.7 ft

⇒ Increase in the length of one side = 20.5 - 16.7 = 3.8 ft
