Answer:
12 in diameter bed will give better value
Step-by-step explanation:
Given:
Cost of cover 12 in diameter bed = $150
Cost of cover 18 in diameter bed = $300
Find:
Better value
Computation:
Area of bed = πr²
Area of 12 diameter of bed = (22/7)(6)²
Area of 12 diameter of bed = 113.14 in²
Area of 18 diameter of bed = (22/7)(9)²
Area of 18 diameter of bed = 113.14 in²
Area of 18 diameter of bed = 254.57 in²
Compare cost of bed 1 = 113.14 / 150 = 0.75 in per dollar
Compare cost of bed 2 = 254.57 / 300 = 0.84 in per dollar
So,
12 in diameter bed will give better value
It’s 3.9 because if you write out the metric system K H D L D C M. From milliliters to liters is three spaces so for the num. 3900 go backwards three spaces
Answer:
explained
Step-by-step explanation:
a. daily requirement of milk = 4 liters
15 liters of milk is present
this 15 liters of milk will be used up in 
days
= 3(3/4) days , so after 3 days only more milk will be required to purchase.
b. daily milk consumption is reduced to half = 2 liters
Now, 15 liters of milk will be used up in 
= 7.5 or 7(1/2) days.
Hence now milk will be purchased after 7 days.
Answer:
D) x = 3 , x= 10.
Step-by-step explanation:
Given : x²-13x+30=0
To find : Use the zero product property to find the solutions to the equation.
Solution : We have given
x²-13x+30=0
On factoring
x²-10x -3x +30=0
On taking x common from first two terms and -3 from last two terms .
x ( x - 10 ) - 3( x - 10 ) = 0
On grouping
(x -3) ( x -10) = 0.
By the zero product property
x -3 = 0
x = 3 ,
For x - 10 = 0.
x = 10.
Therefore,D) x = 3 , x= 10.
