Answer:
5
Step-by-step explanation:
35 divided by the square root of 14. The square root of 14 is 7. 35 divided by 7 is 5.
A complete load of concrete = 8 parts gravel + 7 parts water + 5 parts cement.
Total number of parts in every load = 8 + 7 + 5 = 20 parts
If total load = 220 kg, then 20 parts = 220 kg
Divide each side by 20 : 1 part = 11 kg
gravel = 8 parts = 8 x 11 kg = <em>88 kg</em>
water = 7 parts = 7 x 11 kg = <em>77 kg</em>
cement = 5 parts = 5 x 11 kg = <em>55 kg</em>
<u>Check:</u> 88 + 77 + 55 = 220 yay !
0.30 times 36 equals 10.80. The answer is $10.80

Answer:
D) c - 2 = 25 + c + 10√c
Step-by-step explanation:
The given equation is 
Taking square on both sides, we get
Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.
c - 2 = 5^2 + (√c)^2 + 2(5)√c
c - 2 = 25 + c +10√c
Answer: D) c - 2 = 25 + c + 10√c
Thank you.
