Suppose the radius of a circle is 8. what is its circumference
Answers
Answer 1
Answer:
16 because the circumference is 2x the amount of the radius :) please give 5 stars and a thankyou button :)
Answer 2
Answer:
First, here is the formula for finding circumference using the RADIUS: C (circumference) = 2 x pi (3.14) x r (radius) using the DIAMETER: C = pi (3.14) x d (diameter) ------------ Using the above formula, just plug in the numbers!! C = 2 x (3.14) x (8) C = 50.24 50.24 is your answer
if you wanted to use diameter, you should know that diameter is just the radius times 2!

Brine is a solution of salt and water. If a tub contains 50 gallons of a 5% solution of brine, how much water must evaporate to change it to an 8% solution?
Answers
Let x = amt of water evaporated :.05(50) = .08(50-x) 2.5 = 4 - .08x .08x = 4 - 2.5 .08x = 1.5 x = 18.75 lb of water evaporated : ; Check; amt of salt remains the same, only the percentage is different, right? .05(50) = .08(50-18.75) .05(50) = .08(31.25) 2.5 = 2.5
Milli plans to rent a room for her birthday party for $40. The catering charge is $12 per person but there is no charge for Milli's meal since she is the guest of honor. If Milli has $100 to spend on her birthday party, how many guests can she invite?
Answers
Since Milli has $100 to spend on her birthday party and she will pay $40 so the remaining money left for her party is $60. For the $60 left she will then pay $12 for each guest for catering. Divide $60 by $12, the answer is 5. Therefore Milli will have 5 guests for her birthday.

5

Two cupcakes require 2/3 of a cup of icing with one cup of icing. How many cupcakes would you be able to frost?
Answers
To determine how many cupcakes you can frost, you need to find the ratio of cupcakes to icing required. According to the given information:
- Two cupcakes require 2/3 of a cup of icing. - This means that one cupcake requires (2/3) / 2 = 1/3 cup of icing.
Now, you can calculate how many cupcakes can be frosted with one cup of icing:
Number of cupcakes frosted = (1 cup of icing) / (1/3 cup of icing per cupcake)
Number of cupcakes frosted = (1 cup) / (1/3 cup) = 3 cupcakes
So, with one cup of icing, you would be able to frost 3 cupcakes.
( 4,?)Is on the line y=2×+3. find the other half of the coordinate
Answers
(4, ?). Let ? = b
(4, b) on line y = 2x + 3
x =4, y = b.
y = 2x + 3
b = 2*4 + 3
b = 8 + 3
b = 11.
The other half of coordinate is 11.
You do y=2x(4)+3 that equals 11 so the coordinate is (4,11)
