Answer:
Height of a cell tower is, 30 m
Step-by-step explanation:
Proportion states that the two fractions or ratios are equal.
As per the given statement:
Let height of a cell tower be h.
Height of a pole = 3m ,
Shadow of a pole = 4 m and
shadow of a cell tower = 36+4 = 40 m
By definition of proportion;
Substitute the given values we get;
by cross multiply we get;
Divide both sides by 4 we get;
h = 30 m
Therefore, the height of a cell tower is, 30 m
11x-2
You combine same so
4x-1x =3x
3x +8x= 11x
11x-2
Answer:
The answer is 20 hours
Step-by-step explanation:
20x60=1200
1200÷60=20
Answer Step-by-step explanation:
Word (story) problems are easy if you use a table to translate the words to precise, concise math variables and operations. For example,
Is means =
Larger than +
Four times a 4*a
F is 550 less than S F = S – 550
Total of A, B, C A + B + C
This seems obvious – until you get stuck on a word problem. So,
“the first company” , “a second company” becomes Let their costs be F and S
Let K be the number of kilograms
“$20 to ship a medium box, plus an additional $2 per kilogram” F = $20 + 2*K
“10 for the same size of box, plus an additional $3 per kilogram” S = $10 + 3*K
“the two shipping methods will cost the same amount” F = S
“What is that weight?” report K
Now, the math:
F = S
20 + 2K = 10 + 3K
$10 = K
