Iron bridge is the first bridge to be ever built
Answer:
8 inches
Step-by-step explanation:
Volume of a cube: side length cubed
x^3=512
Taking the cubic root of both sides, we get
x=8
It is twice the number 32
Answer:
0.024h
Step-by-step explanation:
We have the equation:
t 10 + t 15 = 0.6
<=> 25t = 0.6
<=> t = 0.024
It means that, it takes 0.024h for two people to complete 60% of the task
I hope it will find you well.
Answer:
389 people
Step-by-step explanation:
Step 1
we convert 1500 inches to feet
1 inch = 0.0833 feet
1500 inches = x feet
x = 1500 × 0.0833
x = 125 feet
Step 2
We create a proportion
Since it is on both sides
20/9ft × 10ft = x/7 feet × 125 feet × 2
20/90 = x/1750
Cross Multiply
90 × x = 20 × 1750
x = 20 × 1750/90
x = 35000/90
x = 388.88888889
approximately = 389 people
