Answer:
36 days.
Step-by-step explanation:
60 + 15 = 75 soldiers.
By proportion the number of days that the provisions will last
= 45 * (60/75)
= 45 * 4/5
= 36 days.
We need to create two expressions, then equate them in order to find the numbers of hours.
Let X = Number of hours
Let 1200+18x = Company A (Flat Fee + Hourly Rate*Hours)
Let 900+23x = Company B

After 60 hours, the prices will be the same
Answer:
This looks like homework so you should try to figure it out yourself.
Step-by-step explanation:
The triangle CID will be the same as triangle 21KG and the triangle ABH will be the same as JFE because they are both directly proportional to each other.
Step-by-step explanation:

Answer:
Hi there!
We've given with the base area and height. We know the formula for base area
Base area = πr²
154 = 22/7 × r²
154 × 7/22 = r²
49 = r²
√49 = r
7 = r
Now
TSA = 2πr(h + r)
TSA = 2 × 22/7 × 7(7 + 20)
TSA = 44(27)
TSA = 1188 cm²
