Answer:
50% value change.
Step-by-step explanation:
A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.
Therefore, $15 is a 50% percent change from $10.
C = 2πr or C = πd
Diameter d = 57 cm
C = πd
C = π*57 = 57π
C ≈ 57 * 3.14159 = 179.07063
Exact circumference is 57π cm or
≈ 179.07 cm.
Answer:
Step-by-step explanation:
An estimate is usually a guess, but I somehow think that's not what you want.
She starts with 4 2/3 cups of batter. When she divides it into two, one of the batters has 2 1/4 cups. That's the one she puts blueberries in.
The other batter is the one you are interested in. How big is it?
Estimate: One
The estimated size would be 4 2/3 - 2 1/3 = 2 1/3 which is an estimate. It is just taking the closest number to use so you don't have to grab your calculator.
Actual Size: Two
4 2/3 - 2 1/4 is the size of the second batter. Since 2/3 is greater than 1/4 you need only subtract the whole numbers and then the fractions.
<em><u>Whole number subtraction:</u></em> 4 - 2 = 2
<em><u>Fraction subtraction:</u></em> 2/3 - 1/4
Find the Lowest common multiple between 3 and 4: It is 12. 3 and 4 are prime to each other. They have nothing in common.
- 2/3 to 12s: (2*4)/(3*4) = 8 / 12
- 1/4 to 12s: (1 *3) / (4*3) = 3/12
- 8/12 - 3/12 = 5/12
So the actual size of the batter containing the walnuts is 2 5/12
Answer:
x=k/4+c/4
Step-by-step explanation:
4x-c=k
4x=k+c
x=k/4+c/4
Sort the data into this order:
2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2
^
there are 10 data points in total, therefore the Interquartile Range = between the 5th and the 6th numbers, which are 5 and 6
(5+6)/2= 5.5
