Answer: Half of a ton equals to 1,120 pounds.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Since 80 stones make up half of a long ton, and each stone weight is 14 pounds, to obtain the number of pounds in half of a long ton we simply have to multiply the number of stones (80) by the weight of each stone (14)
Mathematically speaking:
<em>14 x 80 = 1,120 pounds
</em>
Half of a ton equals to 1,120 pounds.
Answer:
The correct option is b: 6 seconds.
Step-by-step explanation:
The formula is:
Where:
t: is the time
h: is the height = 384 ft
When the stone hit the ground, h = 0
To solve the above quadratic equation we need to use the following formula:
(1)
Where:
a: is the coefficient of t² = -16
b: is the coefficient of t = 32
c: is the independent term = 384
By entering the above values into equation (1) we have:
Since we can not take the negative value of time (t₂) equal to -4, the answer is 6 seconds.
Therefore, the stone will hit the ground in 6 seconds. The correct option is b: 6 seconds.
I hope it helps you!
Answer:
858 Remainder 4
Step-by-step explanation:
5 times 5 times 5 is 125.
1 times 1 times 1 is 1.
So you can fit 125 books into the box.
For this problem, you need to create a proportion.
40 inches/12 minutes=100 inches/x
Let x be the number of minutes it takes to weave 100 inches
Solve
40x=1200
x=30 minutes
