Answer:

Step-by-step explanation:

Price per pound of the walnuts = $ 6.50

Price of 4 pounds of the walnuts = 4 *6.50 = $ 26

Amount needs to be paid = Price of 4 pounds of walnut - coupon amount

= 26 - 3.75

= $ 22.25

Expression:

Cost to buy p pounds of walnuts = p * 6.50 = 6.5p

Cost to buy p pounds of walnuts, assuming at least one pound is purchased = 6.50 + 6.5p

Answer:

Step-by-step explanation:

What this question is asking of you is what is the greatest common divisor of 12 and 15. Or, what is the biggest number that divides both 12 and 15.

in order to find this we have to split each number into it's prime components.

for 12 they are 2,2 and 3 (

⋅

)

and for 15 they are 3 and 5 (

⋅

)

Out of those two groups (2,2,3) and (3,5) the only thing in common is 3, so 3 is the greatest common divisor. That tells us that the greatest number of groups that can exist and have the same number of girls and the same number of boys for each group is 3.

Now to find out how many girls and boys there are going to be in each group we divide the totals by 3, so:

girls per group, and

boys per group.

(just as a thought exercise, if there were 16 boys, the divisors would have been (2,2,3) and (2,2,2,2), leaving us with 4 groups [

] of 3 girls [12/4] and 4 boys [16/4] )

Trina has $1000 to purchase an open-top cylindrical dog pen in her backyard. She wants the height of the pen to be 5 feet. If th

RideAnS [48]

Answer:

C. 31.83 feet.

Step-by-step explanation:

We have been given that Trina has $1000 to purchase an open-top cylindrical dog pen in her backyard. She wants the height of the pen to be 5 feet.

First of all, we will find the surface area of dog pen using surface area of cylinder.

$\text{Surface area of cylinder}=2\pi rh$ ,where,

r = Radius of cylinder,

h = Height of cylinder.

$\text{Surface area of cylinder}=2\pi r*5$

$\text{Surface area of cylinder}=10\pi r$

Since the area of each square foot of pen costs $1, so in $1000 Trina can cover an area of 1000 square feet.

Now, we will set the surface area of cylinder equal to 1000 to solve for the radius.

$1000=10\pi r$

Upon dividing both sides of our equation by 10 pi we will get,

$\frac{1000}{10\pi}=\frac{10\pi r}{10\pi}$

$31.8309886=r$

$r\approx 31.83$

Therefore, the radius of the dog pen is 31.83 feet and option C is the correct choice.
