For number 1, add the sides of the triangle. They are all given. The answer is 19.
For number 2, you use the formula for circumference, 2 times pi times radius. The answer is 43.96.
For number 3, I assume that 5 is half of one side. You would double 5 to get ten and multiply it by four, since there are four sides in a square. The answer is 40.
For number 4, you would multiply 5 times pi, but don't solve it. ( since the directions are to leave the answer in terms of pi) The answer is 5 pi.
For number 5, add all the sides together like number 1. The answer is 18.
Answer:
x = 117km
Step-by-step explanation:
a1 = 18 km
q = 90% = 90/100 = 0.9
a2 = a1 • q = 18 • 0.9 = 81/5 = 16.2 km
a3 = a2 • q = 16.2 • 0.9 = 729/50 = 14.58 km
n = 10
x = a1 • q^n - 1/q - 1 = 18 • 0.9^10 - 1/0.9 - 1 = 117km
Answer:
<u>x = 1.07</u>
Step-by-step explanation:
13 ( 6x - 9) = -33
78x - 117 = -33 ( opening brackets and multiplying )
78x = 84 ( - 117 taken to the other side makes it positive)
x = 84 / 78
x = <u>1.07</u>

Answer:
Coupon 2
Step-by-step explanation:
If you were to use coupon 1 the price will be $28.80 because %40 of $18 will be $10.80 (18 x 0.40) then add it to the other 18$ and it will sum up to $28.80. If you were to use coupon 2 the price will be $27 because if you were to take %25 of the sum of both sweaters ($36) it would be $27 (36 x 0.25).
