Answer:
no, it is good for 2 weeks (almost 3)
Step-by-step explanation:
The volume of the pool is ...
V = LWH
V = (20 m)(8 m)(1.8 m) = 288 m³
Then the amount of chlorine powder needed for 1 week is ...
(300 g/(50 m³)) × (288 m³) = 1728 g
A box of 5000 g holds enough chlorine for ...
(5000 g)/(1728 g/treatment) = 2.89 treatments
A box of chlorine powder is enough for 2 weeks, not 4.
Answer:
The correct answer is area of the coffee shop sign and that is equal to 254.57 square inches.
Step-by-step explanation:
A coffee shop sign is in the shape of a circle.
The sign measures 18 inches across in diameter.
Thus the radius of the coffee sign is 9 inches.
We need to find the measurement that is closer to the measurement in square inches.
Thus invariably means we need to find the surface area of the coffee shop sign.
Area in square inches of the coffee sign is given by π × where r is the radius of the circle. Therefore area is π × = 81 π = 254.57 square inches.
Given:
The function is
To find:
The inverse function .
Solution:
We have,
Step 1: Putting f(x)=y, we get
Step 2: Interchange x and y.
Step 3: Isolate variable y.
Taking cube on both sides, we get
Step 4: Putting , we get
Therefore, the correct option is C.
Answer:
9.4395
Step-by-step explanation:
5% of 8.99= 0.4495
cost of lip gloss8.99
$8.99+$0.4495=$9.4395
10/2 = 5 (plot on number 5 of number line)
