Answer:
Volume = 10562.96 cu ft
10.56 hr. to drain all the water
Step-by-step explanation:
V = 1/3Bh B = area of the base h = height
The base is a circle, so 
= 10562.96 cu ft
10562.96/1000 = 10.56 hr.
Answer:
a) (15 × 32) + (15 × 68)
b) Distributive property
c) $1500
Step-by-step explanation:
A vendor supplies 32 litres of milk to a hotel in the morning and 68 litres of milk in the evening. If the milk costs Rs 15 per litre,
a. Write a numerical expression for the given statement.
The numerical expression for the given statement is written as:
$15 × 32 liters + $15 × 68 liters
15 × 32 + 15 × 68
B. Which property of whole numbers would you use to form a numerical expression for the given statement?
The property that I would use to form a numerical expression is a distributive property
a × (b + c) = (ab + ac)
Where a = $15
b = 32 liters
c = 68 liters
Hence:
15 (32 + 68) = (15 × 32) + (15 × 68)
C. How much money he gets per day for the supply?
The amount he gets per day:
15 (32 + 68) = (15 × 32) + (15 × 68)
= $1500
-5x -3x + 7x
-8x + 7x
-x
Thus, second option is correct.
Kendall and Sophia swam (2n - 12) laps together
<em><u>Solution:</u></em>
Given that, Kendall Swam (n) laps in the pool
To find: Number of laps swam together
From given statement,
Number of laps by Kendall = n
Also, Sophia swam 12 less than Kendall
Therefore, number of laps swam by Sophia is 12 less than the number of laps by Kendall
Number of laps by Sophia = Number of laps by Kendall - 12
Number of laps by Sophia = n - 12
<em><u>How many laps did they swim altogether ?</u></em>
Number of laps swam together = Number of laps by Kendall + Number of laps by Sophia
Number of laps swam together = n + n - 12 = 2n - 12
Thus they swam (2n - 12) laps together
