The answer is "3600 ft²".
Left triangle area=(1/2) x (30 ft) x (72 ft) = 1080 ft²
Middle walkway area=(20 ft) x (72 ft) = 1440 ft²
Right triangle area
=same as left triangle area, 1080 ft²
Total area1080 ft²+1440 ft²+1080 ft² = 3600 ft²
Now you can also check that;
Parallelogram area = base x height = (50 ft) x (72 ft) = 3600 ft²
Answer:
16 and 48
Step-by-step explanation:
let the 2 integers be x and 3x ← ratio 1 : 3
Then
3x - x = 32 ← difference between the integers
2x = 32 ( divide both sides by 2 )
x = 16
and 3x = 3 × 16 = 48
Since magnitude of difference is 32
We can also express the difference as
x - 3x = 32
- 2x = 32 ( divide both sides by - 2 )
x = - 16
and 3x = 3 × - 16 = - 48
The 2 integers are 16 and 48 or - 16 and - 48
Do you have an equation that I can use?
Let's add the fractions first and then we can estimate the sum.
= 31/4 + 17/3 + 8/18
change to common denominators
= 279/36 + 204/36 + 16/36
add numerators only
= 499/36 or 13 31/36 or 13.86
ANSWER: (B) 13 is the best estimate of the answer. Normally we round up to 14 with a number like 13.86, but since that is not a choice, we can estimate 13 as the answer.
