12% is equal to the ratio ____ to 100.
Answer:
12 to a 100
Step-by-step explanation:
12% is basically 12/100
12% is equal to the ratio 12 to 100.
What is Percentage?
Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
Here, we know that
percentage = Quantity per unit 100
12% = 12 / 100
Thus, 12% is equal to the ratio 12 to 100.

Answer: $125
Step-by-step explanation:
1/80=x/10,000
10,000/80=125
Hope this helped!
Answer:125 yen
Step-by-step explanation:
Ratio and proportion
Ratio=1:80=x:10,000
x represents dollars which is unknown
1/80=x/10,000
Then you cross multiply
80x=10,000
80x/80=10,000/80
x=125

525
Step-by-step explanation:
If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Answer: The difference between the angle measure is 152 degrees
Step-by-step explanation: Supplementary angles are angles that add up to 180
So if one angle is x in this case, the other will be 14x
Adding both ;
x + 14x = 180
15x = 180
x = 180/15
x = 12
The other angle is 14 * 12 = 168
The difference between the two will be;
168-12 = 156
Answer:
168
Step-by-step explanation:
m<B + m<C = 180 since the angles are supplementary.
m<B = 14m<C since the measure of angle B is 14 times the measure of angle C.
m<B + m<C = 180
14m<C + m<C = 180
15m<C = 180
m<C = 180/15
m<C = 12
m<B = 14m<C = 14 × 12
m<B = 168
Answer: 168

To control his weight, Joel reduced his calorie intake from 2500 calories to 1950 calories each day. What was his percent of decrease for calorie intake?
SHOW ALL WORK PLZ
Answer:
22% decrease. Joel is consuming 78% of the amount of calories he previously consumed.
Step-by-step explanation:
1950 = 2500x
x = 1950 / 2500
x = 0.78
1 - 0.78 = 0.22
Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

[2] Answer:x = 67°
Step-by-step explanation:Same-side interior angles are supplementary.
x° + 113° = 180°
x° = 180° - 113°
x = 67°
[3] Answer:r = 2°
Step-by-step explanation:The little box represents 90 degrees, meaning that these angles are complementary.
9r + 2° + 70° = 90°
9r + 72° = 90°
9r = 18°
r = 2°

Here is a easy question: What is the mean of the data set {32,20,40,44,21,38}?
Answer:
32.5.
Step-by-step explanation:
32 + 20 + 40 + 44 + 21 + 38 = 52 + 84 + 59 = 195
There are 6 terms in the data set.
195 / 6 = 65 / 2 = 32.5.

What is the interquartile range of this data set?
Answer:
IQR = 13
Step-by-step explanation:
First, lay out the set of data in a line.
20, 25, 30, 30, 31, 40, 41, 49
Next, we have to find the median, which is the middle of the set of data.
It is between 30 and 31, which is 30.5. Another way to find it is:
30 + 31 = 61
61 ÷ 2 = 30.5
Using that, we mark it between 30 and 31. Next, use the line of the mark, you use to separate the data into two.
20, 25, 30, 30 | 31, 40, 41, 49
Now, you find the median for each side. The left side will be the lower quartile, and the right side will be the upper quartile.
LQR = 25 + 30 = 27.5
UQR = 40 + 41 = 40.5
Now to find the IQR, you subtract the LQR from the UQR:
40.5 - 27.5 = 13
IQR = 13
