At noon, the temperature was 36 degrees. At midnight, the temperature was 30 degrees. By 6:00 am it drooped 5 degrees. Since it dropped 5 degrees, you subtract 5 from 30, which equals 25. It then increased by 11 degrees. Since the temperature increased, you add 11 to 25, which equals 36. At noon, the temperature was 36 degrees.
Answer: Chiara's monthly payment is $194.7
Step-by-step explanation:
The cost of the new natural gas barbecue for $2,100. She made a down payment 30% off the purchase price. This means that the amount of down payment made is
30/100 × 2100 = 0.3 × 2100 = $630
Amount left to pay would be
2100 - 630 = $1470
The formula for determining monthly loan payment is
A = P(r(1 + r)^n)/((1 + r)^n - 1)
There would be 9 monthly payments, so
n = 9
r = 0.055/12 = 0.0046
P = 1470
A = 1470(0.0046(1 + 0.0046)^9)/((1 + 0.0046)^9 - 1)
A = (1470 × 0.0049)/0.037
A = 7.203/0.037
A = 194.67
Answer:
x = - 4, x = 9
Step-by-step explanation:
Given
x² - 36 = 5x ( subtract 5x from both sides )
x² - 5x - 36 = 0 ← in standard form
(x - 9)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 9 = 0 ⇒ x = 9
x + 4 = 0 ⇒ x = - 4
