sounds like you need a question!!!
The answer 456 fe
Because it the benefit is doing today
Answer: 2 Fahrenheit per hour
Step-by-step explanation:
From the question, we are given the information that the outside temperature decreases by 7 fahrenheit in 3 1/2 hours.
The temperature change as a unit rate will then be calculated as:
= 7 ÷ 3 1/2
= 7 ÷ 7/2
= 7 × 2/7
= 2 Fahrenheit per hour
It Decrease at 2 Fahrenheit per hour
Teh answer is 1/12. 1/4+ 2/3 is 11/12. First, you need to find the common denominator of 4 and 3, and that is 12.Then, you multiply 1*3 because 4*3 is 12.You then have the fraction of 3/12. Then, you multiply 2*4 because again, what you do to the top, you also do to the bottom, so you would also have the fraction of 8/12.The rest is easy. 3/12 + 8/12 is 11/12.And the missing piece of 11/12 is 1/12, because that made it whole.
Hope that helps!
When 'y' is directly proportional to 'x', we express this by
y = kx
where 'k' is the constant, which we need to work out first
Cost of circular mirrors = (k) (diameter)²
50 = k(60)²
50 ÷ 3600 = k
the proportional formula is
y = (1/72)x²
The cost of the mirror when diameter = 90cm
y = (1/72) (90)²
y = 112.5
Answer: $112.50
