Answer:
9670 feet
Step-by-step explanation:
The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?
<em>we translate word problem to equation.</em>
<em />
<em>8219.5 IS 85% of TOTAL</em>
<em />
Firstly, 85% = 85/100 = 0.85
Remember, is means =
of means multiplication
So we have:
<em>8219.5 = 0.85 * Total</em>
<em>Hence, total = [let total be 7]</em>
<em>8219.5 = 0.85 * t</em>
<em>t = 8219.5/0.85 = </em><em>9670 feet</em>
Answer:
24, 48, 108
Step-by-step explanation:
2:9:4
2x+9x+4x=180
15x=180
x=12
2(12)=24
9(12)=108
4(12)=48
If they were equal both times they checked this means that 15% of their $ was equal to $210
so 15/100 = 210/x
so .15x=210
x=210/.15
x = 1400
Answer:
C
Step-by-step explanation:
If x = a is a zero of f(x) then (x - a) is a factor of f(x)
Here the zeros are x = 6 and x = - 4 then the corresponding factors are
(x - 6) and (x - (- 4) ) , that is (x - 6) and (x + 4)
Then f(x) is the product of the factors
f(x) = a(x - 6)(x + 4) ( a is a multiplier )
If a = 1 , then
f(x) = (x - 6)(x + 4) ← is a possible choice → C
