Answer:
738cm^3
Step-by-step explanation:
You just multiply everything together
12.3 * 7.5 * 8 = 738cm^3
<u>Answer:</u>
The height of the tower nearby the pole is 102 m.
<u>Solution:</u>
Given,
Height of the pole = 3.5 m
Length of the shadow of the pole = 1.47 m
Length of the shadow of the tower nearby = 42.75 m
Let us assume the height of the tower as x
On solving for x we get,
On rounding off to the nearest meter we get,
x=102 m
The height of the tower is 102 meter.
Start by assigning a variable name to the "number" -- call it x.
Now write out what they say:
"The product of 1/3 and the sum of a number and 3" -- that's 1/3 times x + 3, or (1/3)(x + 3) or (x + 3) / 3
It's "between negative one and five"
So that means:
-1 < (x + 3) / 3 < 5
So now solve this inequality. First multiply everything by 3.
-3 < x + 3 < 15
Subtract 3 from all the terms:
-6 < x < 12
So the answer is, all numbers between -6 and 12
