Answer:
6 ft longer (total length of 15ft)
Step-by-step explanation:
the initial dimensions are:
length: 
width: 
the area area of the garden is given by:
so the original area is:
Since we need the area to be 
, and we can only change the length, the width will still be 8ft.
We substitute the value of the new area and the width to the equation for the area:
and we clear for the new length:
The length of the garden for the area to be , must be 15ft.
This means that if originally the length was 9 ft, now it has to be 6 ft longer.
Answer:
C: 9076.3 cm^3
Step-by-step explanation:
Use the formula for the volume of a cylinder.
V=πr^2 times h
h=25
Here, I'm assuming 21.5 cm is the diameter, so divide 21.5 cm by 2 to get 10.75 as r.
V=(10.75^2)π times 25
115.5625π times 25
This is about 2889π
This simplifies best to choice C, which is about 9076.3 cm^3
However, if I was wrong about 21.5 cm being the diameter, my answer is wrong. If 21.5 cm is r, choice D is the correct answer. If 21.5 cm is the diameter, C is the answer.
Answer: 1/6
Step-by-step explanation: There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.
5+7c
you can’t add the c and the regular number unless they have the same variable
