Since the truck is 8 feet long then the longest log able to fit in the truck should be 8 feet as well. However talking reality, we might want to shorten it to make it fit better. Hope this helps!

Use 1% or 10% to estimate 93% of 149 A. 169.5 B. 13.5 C. 112 D. 135

irakobra [83]

93% of 149

10% of 149 = 14,9

93% of 149 > 90% of 149

93% of 149 > 149 - 14,9 ≈ 149-15≈134
> 134
⇒ the answer is D

New streetlights will be installed along a section of the highway. The posts for the streetlights will be 7.5 m tall and made of

SIZIF [17.4K]

First, we determine the volumes of the posts may it be cylindrical in shape or rectangular prism.

(A) cylindrical:
( π(26.7/100)² - π(24.2/100)²)*(7.5) = 0.3 m³
(B) rectangular prism:
(40/100)²(7.5) - (35/100)²(7.5) = 0.28125 m³

Then, we calculate for the amount of substance
(A) cylindrical: (0.3 m³)(2700 kg/m³) = 810 kg
(B) rectangular prism : (0.28125 m³)(2700 kg/m³) = 759.375 kg

Then, calculate for the costs
(A) (810 kg)($0.38/kg) = $307.8
(B) (759.375 kg)($0.38/kg) = $288.56

Thus, the answer for A is rectangular post
B. About $19.24 can be saved.

True of False: (log x)^2=2log x. Explain your answer and show your work

Lubov Fominskaja [6]

False.
Only log(x^2)=2log(x)
For example, let x=10
(log(10))^2=1^2=1
yet 2log(10)=2*1=2
