<u>Answer: </u>
The equation of the circle with center (0, 1) and a radius of 10 is 
<u>Solution:
</u>
Equation of circle whose center (h, k) and radius r is given as,
---- eqn 1
From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.
Hence we get, h = 0 ; k = 1; r = 10
By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as

On Simplifying we get

Expand
using the formula 




Hence equation of the circle with center (0, 1) and a radius of 10 is 
120 people who all need 1 drink, so if each drink needs .5 cups of concentrate you will do 120d × 0.5 = 60 total cups of concentrate. if you then set up a fraction, you could cross multiply to get the answer, but I cant do fractions here so I'll say this: if every 5 cups of concentrate gives 19 cups of water, then you divide 60 cups by 5 cups to see how many "batches" of this recipie you will need, you get 12 batches, so 12 x 19 (cups of water per batch) to get 218 ( I think, check my math with a calculator
Answer:
b=0.25×80
or
b=1/4×80
Step-by-step explanation:
We know that bike equals 25%, so we just need to find 25% of 80.
b=0.25×80.
The answer is B.
This is because since f + e = c,
then a² + b² = c(f + e)
a² + b² = c(c)
a² + b² = c²
This is the correct answer
A.
since the tip was a procentage from the pre-tax amount
