The value for c is A. 49. That comes from the process of completing the square where you take half the linear term, square it, and add it in. Our linear term is 14. Half of 14 is 7, and 7 squared is 49. So A
Answer:
A medium milkshake will use
of a pint of milk.
Step-by-step explanation:
Given:
A large chocolate milkshake takes =
of a pint of milk
While a medium chocolate takes =
the amount of milk for a large milkshake.
To find the amount of milk required for a medium milkshakes.
Solution:
The amount of milk required for a medium milkshakes is given as:
⇒
of the amount of milk for a large milkshake.
Plugging in the amount of milk for a large milkshake.
⇒
of ![\frac{8}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B9%7D)
by
we mean multiplication.
⇒ ![\frac{1}{7}\times\frac{8}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D%5Ctimes%5Cfrac%7B8%7D%7B9%7D)
⇒ ![\frac{8}{63}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B63%7D)
Thus, a medium milkshake will use
of a pint of milk
About 32.9 minutes have gone by.
To find this answer you take your percent and make it a decimal by dividing it by 100. In doing so, you'll get 0.53. Then multiply 0.53 by 62 to get 32.86. Since you have to round to the nearest tenth, you look at the hundredths place to see whether you round up (5-9) or round down (1-4). In this case, you round up making your answer 32.9 minutes.
I hope this helps!

Answer:
20,27
Step-by-step explanation:
let 13,a,b,34 be consecutive numbers.
a=13
l=34
n=4
l=a+(n-1)d
34=13+(4-1)d
34-13=3d
21=3d
d=21/3=7
a=13+7=20
b=20+7=27
