Answer: 55 people attend aerobics at Martha’s altogether
Step-by-step explanation:
Martha conducts aerobics three times a week in her home.
Number of members in first group = 19 members
Number of members in second group = 22 members ; and
Number of members in third group = 14 members
To find the number of people who attended aerobics we have to add the number of members in all tge three groups.
So, number of people who attended aerobics at Martha’s altogether = 19 + 22 + 14 = 55 members
Hope it helps.

What is the area of the shaded portion of the trapezoid in the figure, in terms of? The figure is not drawn to scale. All of the given measurements are in feet.
Answer:
(150-36π) ft^2
Step-by-step explanation:
we need to subtract the area of the circle from the area of the trapezoid to find the area of the shaded region.
area of circle=πr^2=π6^2=36π ft^2
area of trapezoid=(1/2)(a+b)h=(1/2)(12+13)12=150 ft^2
so, the area of trapezoid-area of circle=(150-36π) ft^2
express the area of the entire rectangle.

The box-and-whisker plot represents the heights (in meters) of the tallest buildings in Chicago.
a. What percent of the buildings are no taller than 345 meters?
About ____
percent of the buildings are no taller than 345 meters.
Answer:
75%
Step-by-step explanation:
The answer is 75% because each point/dot, represents 25% of the data. Below 345 meters are 3 points, therefore 3 * 25% = 75%.
Approximately 75% of the buildings are no taller than 345 meters for the box-and-whisker plot.
What is the box and whisker plot?A box and whisker plot (also known as a box plot) depicts a five-number summary of a set of data: lowest, lower quartile, median, upper quartile, and maximum.
The box-and-whisker plot represents the heights (in meters) of the tallest buildings in Chicago.
We can see that all three of the data points that are less than or equal to 345 meters are included in the lower half of the box-and-whisker plot, which represents the range from the minimum to the median height.
This means 3 × 25% = 75%.
So, we can estimate that approximately 50% of the buildings are no taller than 345 meters.

From 6am to 9am customers arrive in... From 6am to 9am customers arrive in droves to Betty's Bakery for her annual, 1 day only, cake sale. During that 3 hour period 1.75 customers enters the Bakery every minute. Betty and her staff can box cakes and check out customers only at the rate of 70 customers per hour. What is the average waiting time (minutes) for the customers who arrive in this 3-hour period of time?
Answer:
The average wait time for customers arriving in this 3-hour period of time is 1.5 minutes.
Step-by-step explanation:
Since from 6am to 9am customers arrive in droves to Betty's Bakery for her annual, 1 day only, cake sale and during that 3 hour period 1.75 customers enters the Bakery every minute, and Betty and her staff can box cakes and check out customers only at the rate of 70 customers per hour, to determine what is the average waiting time in minutes for the customers who arrive in this 3-hour period of time, the following calculation must be performed:
1.75 x 60 = 105
105/70 = 1.5
Therefore, the average wait time for customers arriving in this 3-hour period of time is 1.5 minutes.
Angle A and angle B are complementary, and their measures
have a difference of 20°. What are the measures of the angles?
Answer:
35° and 55°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x and the other x + 20 , then
x + x + 20 = 90
2x + 20 = 90 ( subtract 20 from both sides )
2x = 70 ( divide both sides by 2 )
x = 35°°
x + 20 = 35 + 20 = 55
The 2 angles are 35° and 55°
The volume of the Hawk’s refrigerator is 30 × 68 × 28.5 cubic inches.
The volume of the Lopez’s refrigerator is (30 × 68 × 28.5) + 16 cubic inches.
Without doing any calculations, which statement describes how the volume of
the Hawk’s refrigerator compares to the Lopez’s refrigerator?
A.
The volume of the Hawk's refrigerator is 16 cubic inches greater than the volume of the Lopez's refrigerator.
B.
The volume of the Hawk's refrigerator is 16 times less than the volume of the Lopez's refrigerator.
C.
The volume of the Hawk's refrigerator is 16 times greater than the volume of the Lopez's refrigerator.
D.
The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator.
Answer:D
Step-by-step explanation:
The correct statement that describes how the volume of the Hawk's refrigerator compares to the Lopez's refrigerator is: Option D.
D. The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator.
From the given information, we get,
The volume of the Hawk's refrigerator is given as 30 × 68 × 28.5 cubic inches.
The volume of the Lopez's refrigerator is given as (30 × 68 × 28.5) + 16 cubic inches.
We can see that the volume of the Lopez's refrigerator is obtained by adding 16 cubic inches to the volume of the Hawk's refrigerator.
Since 16 cubic inches are being added to the Hawk's refrigerator to get the Lopez's refrigerator, the volume of the Hawk's refrigerator must be 16 cubic inches less than the volume of the Lopez's refrigerator.
So, option D, "The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator," is the correct statement.

HCF of 225 and 270 is?
Answer:
I believe it's 45
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
270 = 1*225 + 45
225 = 5 * 45 + 0
HCF = 45
The above is Euclid's method for finding the HCF.
The other method is by finding the prime factors:
225 = 3 * 3 * 5 * 5
270 = 2 * 3 * 3 * 5
We pick out common factors:
So the HCF 3 * 3 * 5
= 45.
