Answer:
Minimum 66 feet of molding that he needs.
Step-by-step explanation:
Given that a square ceiling has a diagonal of 23 ft.
If the sides of the square ceiling are 'a' feet, then applying Pythagoras Theorem we can write, a² + a² = 23²
⇒ 2a² = 23²
⇒ a = 16.2634 feet (Approximate)
Now, the perimeter of the square ceiling will be 4a = 65.05 feet.
If the cost of molding along the perimeter of the ceiling is in per foot, then a minimum of 66 feet of molding that he needs. (Answer)
Answer:
You can not purchase the bicycle.
Step-by-step explanation:
The statement given in the question is if you save at least $150 , you can purchase a bicycle
Saving at least $150 means saving $150 or more. This is to say that you can only purchase the bicycle if your savings are $150 and above.
So saving $135 is less than $150 hence you can not purchase the bicycle.
Answer:
x =-18
Step-by-step explanation:
5(x + 9) = -45
Divide each side by 5
5/5(x + 9) = -45/5
x+9 = -9
Subtract 9 from each side
x+9-9 = -9 -9
x =-18
Carol's Steakhouse, the total cost of serving 150 customers per day is $900. Carol is interested in increasing her business, but is concerned about the effect on marginal cost.
Carol successfully increases her business to 200 customers per day. However, her total cost for doing so is 50% greater than the expected $1,600. What percent greater is the actual marginal cost than the expected marginal cost, to the nearest full perc
Answer:
214
Step-by-step explanation:
We have been given
C1 = $900
Q1 = 259
Then c2 = $1600
Q2 = 200
M = 1600-900/50
= 14
For real,
C1 = 900
C2 = 2400
Q1 = 150
Q2 = 50
1500/50 = 30
30/14 x 100
= 214
It is greater by 214 percent
