Answer: 150.768
Step-by-step explanation:
The volume of the cube is 6×6×6=216 cubic inches. We have that the gold weight 0.698 pounds per cubic inch, so, to find the total weight of the cube of gold we should do 216×0.698 = 150.768. Therefore the weight of the cube is 150.768
500,000 - 100%
10,000 - x
X = (100*10,000)/500,000 = 1,000,000/500,000 = 2%
Answer 2%
Answer:
C
Step-by-step explanation:
80/20 = 4 hours taken by Davie
90 mins = 1.5 hours
Horatio has 4-1.5 = 2.5 hours
Speed: 80/2.5 = 32 miles/hour
1 point because 15 goes into 25 one time.
Answer:
x = 1, y = 3
Step-by-step explanation:
Given:
- 2x + 3y + 4 = 15 ⇒ 2x + 3y = 11
Now let's check the pairs of x and y:
<u>x = 6, y = 3</u>
- 2x + 3y = 2*6 + 3*3 = 12 + 6 = 18 ≠ 11
- incorrect
<u>x = 3, y = 5</u>
- 2x + 3y = 2*3 + 3*5 = 6 + 15 = 21 ≠ 11
- incorrect
<u>x = 6, y = 4</u>
- 2x + 3y = 2*6 + 3*4 = 12 + 12 = 24 ≠ 11
- incorrect
<u>x = 1 , y = 3</u>
- 2x + 3y = 2*1 + 3*3 = 2 + 9 = 11
- correct
