Answer:
- 160 yd³ must be hauled
- $520 is the cost
Step-by-step explanation:
There are 3 feet in a yard, so the volume of the hole is ...
(45 ft)/(3 ft/yd) × (16 ft)/(3 ft/yd) × (6 ft)/(3 ft/yd)
= (15 × 16/3 × 2) yd³ = 160 yd³ . . . volume to be hauled
__
The cost is $13/(4 yd³), so the total cost will be ...
($13/(4 yd³)) × 160 yd³ = $520 . . . cost of hauling
three times a number and five" translates to "3x + 5," while the phrase "three times the sum of a ... The total of six and some number. 6 + x ... The difference of a number and three. X – 3 less. Nine less a number. 9 – X.
Okay so for this, visualize the blocks are stacked on top of each other. Each block is 3/4 of an inch thick so all you have to is multiply 3/4 by 12. So:
×
=
However, the fraction 36/4 is not in lowest terms, so we need to reduce it. List the factors of the numerator and denominator:
Factors of <span>36: 1, 2, 3, 4, 6, 9, 12, 18, 36</span>
Factors of <span>4: 1, 2, 4</span>
<span>
</span>
4 is the largest factor of both 36 and 4, so we need to divide both the numerator and denominator by 4.
Numerator: 36 ÷ 4 = 9
Denominator: 4 ÷ 4 = 1
Write the new fraction: 9/1 = 9
So this is FALSE.
Hope this helps :)
It is equation of Einstein's theory of special relativity that shows that the increased relativistic mass (m) of a body comes from the energy of motion of the body—that is, its kinetic energy (E)—divided by the speed of light squared (c 2).....
