9.4 cm --- 100%
3.5 cm --- x%
x = 3.5/9.4 * 100 ≈ 37.2%
Work:
(s = 150ft
t = 1/4 square root of s)
Square Root (150) = 12.2474487139
12.2474487139 ÷ 4 = 3.0618621785 = ~3.062
Final Answer: About 3.062 seconds.
7.125 is the anwcer to that
Answer: The term 0.040(30h) represents the amount of tax she must pay.
Explanation:
The functin 0.04(30h) + 30h, has two terms; the second term, 30h, represents cost due to h hours at at unit of 30, and the first term 0.04(30h) is the additional amount due to the taxes over h hours at the unit rate of 30.
When you add a tax rate of 4% to 30h, you get the the amount of taxes over the 30h.
The calcualtion is: (4/100)×(30h) = 0.04(30h). Hence, you conclude that 0.04(30h) is the amount of tax she must pay.
Answer:
the answer is -1
Step-by-step explanation:
if you multiply the first equation by -1, you get this:
-3x + 4y = 4
and then you can add that to the second equation and eliminate y
2x + 0y = 16
