A theater sold 85% of the tickets for a
play. If 170 tickets were sold, how many
tickets were originally put up for sale?
Answer:
200 tickets.
Step-by-step explanation:
85% = 85/100 = 0.85
170/0.85 = 200
= 200
Check:
200*0.85 = 170
Answer: hope this helps ♡
200 tickets were originally put up for sale.
Step-by-step explanation:
85% = 170
(we divide 85 and 170 by 85)
1% = 2
(now multiply 1 and 2 by 100)
100% = 200
(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)
Julia's service charge at the salon was $72.60. If she added 20% for tip, how much did she pay total for her service at the salon?

Every New Year's Day, Jennifer brings 13 candies for each of her grandchildren and 20 more candies for the adults to share.
Let g represent the number of Jennifer's grandchildren and c represent the total number of candies she brings.
Find the value of c when g=9.
Answer:
We can use the given information to set up a system of two equations:
c = 13g + 20
c - 13g = 20
The second equation is obtained from the first equation by subtracting 13g from both sides.
To solve this system, we can use substitution.
First, we solve the second equation for c.
c = 20 + 13g
Then, we substitute this expression for c into the first equation.
20 + 13g = 13g + 20
Then, we simplify.
20 = 20
So, the value of c when g = 9 is 20 + 13 * 9 = 20 + 117 = 137.

The chalk circle around the pitcher's mound has a diameter of 16 ft. What is the area of the pitcher's circle?
Answer:
The area is approximately 201.06
Step-by-step explanation:
If you use the equation pi r^2, then we will get the answer. Since the diameter is double the radius, we should know that the radius is 8ft. Then we do the math and get the answer above.
Answer: A≈201.06ft²
Step-by-step explanation:
How to Calculate Diameter?
Diameter = Circumference ÷ π (when the circumference is given)
Diameter = 2 × Radius (when the radius is given)
Diameter = 2√[Area/π] (when the area is given)

Answer:
#5 = option a (129.38 miles):
We are told that the cities are 17.25 inches apart, and that 2 inches equal 15 miles. First we have to divide 17.25 inches by 2 we end up with 8.62500 inches (not simplified yet). Next, we just take 8.62500 inches and multiply that with 15, which leaves us with 129.37500 inches. Then we just round that to the nearest hundredth which will give us 129.38 inches which means 129.38 miles as well!
#2 = option a (2.4 inches)
We know that bigger rectangle's length is 16 inch and that smaller rectangle's length is 3.2 inches. We just have to calculate the decrease of the length and we do that by dividing. We have to do 16 inches divided by 3.2 inches which equals 5. (You can double check that by multiplying 3.2 inches by 5 which would equal 16 inches) Now to find the width of the smaller rectangle, we just have to divide the width of the bigger rectangle, which is 12 inches, by 5 which would give us 2.4 inches!
#4 = ?
#6 = option c (7.2cm)
So basically I just did 25cm divided by 10cm which equals 2.5cm. (You can also do 25cm divided by 2.5cm to get 10cm if you want to double check). Then I just did 18cm divided by 2.5 cm which led me to the answer 7.2cm)

Tell whether ratios form a propotion

18/24; 15/20
someone help me pls:(
Answer: Ratios form a proportion if they are equal when cross-multiplied.
1/4 and 3/12
Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.
So they are equal and form a proportion.
54/10; 81/15
Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.
So they are equal and form a proportion.
18/24; 15/20
Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.
So they are equal and form a proportion.
Hence, all the ratios mentioned above form a proportion.

In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 12 times out of 15 attempts. Tasha has hit the ball 9 times out of 10 attempts. Which player has a ratio that means they have a better batting average?
A:Tasha, because she has the lowest ratio since 0.9 > 0.8
B:Tasha, because she has the highest ratio since 27 over 30 is greater than 24 over 30
C:Jana, because she has the lowest ratio since 0.9 > 0.8

Answer: This is the best I could find for you
Step-by-step explanation:
"When the ratio of part to whole is equal to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion."

A sports medicine major wanted to conduct an experiment to determine if there is a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:
The time for 22 leg-press reps is 11.9 seconds.
Step-by-step explanation:The lines of best fit is the trend line of the dataset.
The equation of line of best fit is y = 0.120x + 9.274The time for 22 leg-press reps is 11.9 seconds(A) The equation of the line of best fitThe table is given as —
(x) : 12 32 7 26 28 15 1
(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5
To determine the equation of line of best fit, we make use of a regression calculator.
Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)
(B) The number of seconds for 22 leg-press repsThis means that x = 22.
So, we have:
y = 0.120 * 22 + 9.274
= 2.640 + 9.274
= 11.914
(Approximate to the nearest hundredths)
= 11.9
Hence, the time for 22 leg-press reps is 11.9 seconds.
