A photographer is making an enlargement of a color portrait. If the original portrait is 11 inches by 14 inches and he wants to make the new width 14 inches, about how long should the enlarged length be?
Answers
The width of the original is 11 inches.
The ratio of the width is 14/11
Set up a ratio for the new length:
14/11 = 14/X
Cross multiply:
11x = 196
Divide both sides by 11:
x = 196/11
x = 17.8 inches. (Rounded to the nearest tenth)

a baby gorilla had a mass of 2620 grams at birth, 2960 after 10 days, and 3300 grams after 20 days. What is the average number of grams that the baby gorilla grew each day during the first 10 days and during the next 10 days?
show work
Answers
The baby gorilla grew 340 grams in the first 10 days. This is an average of 34 grams per day. The baby gorilla grew 340 grams in the next 10 days. This is an average of 34 grams per day. The baby gorilla grew at the same rate in the first 10 days and the next 10 days.
Here is the solution:
340 grams / 10 days = 34 grams per day
340 grams / 10 days = 34 grams per day
34 grams per day = 34 grams per day
Therefore, the average number of grams that the baby gorilla grew each day during the first 10 days and during the next 10 days is 34 grams per day.

Step-by-step explanation: Each cube has a total of 6 sides. In the model, the top cube has 1 "hidden" side/1 side that is not exposed to the paint, the bottom middle has 1 "hidden" side, the right bottom cube has 1 "hidden" side, and so does the left. Adding up all the sides that are not exposed to the paint, there is a total of 4 white sides.
The cubes are stuck together in three places
2 faces are glued at once
2 faces x three places = 6
6/24 faces are white
*****100 POINTS****** please help me with this area of a circle question.
Answers
Answer: 12 cm
Step-by-step explanation: In order to do this, you have to know that the formula for the area of a circle is pir^2. Pi times the radius squared is equal to 36 pi. Well, 6 squared is 36, and 36 times pi is 36 pi. So that means that the radius is 6. Then, the radius is half the diameter, so the diameter is 12.
For each ordered pair, solve the percent problems to find the coordinates. (x is 110% of 10 y% of 50 is 3.5).
Answers
Step-by-step explanation:
The value of x and y based on the percentages that are given will be 11 and 7.
How to calculate the percentage
Since x is 110% of 10. This will be;
= 110% × 10
x = 11
Since y% of 50 is 3.5. This will be:
y% × 50 = 3.5
y% = 3.5/50
0.01y = 3.5/50
y = 7
Therefore, it can be seen that value of x and y based on the percentages that are given will be 11 and 7.

Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Choose the diagram that shows the graph of the inequality
Answers
Answer: C
Step-by-step explanation:
First, simplify the inequality:
x - 2 ≤ 1 add 2 to both sides
x ≤ 3
If x is less than or equal to 3, the graph should be decreasing, starting from 3. (C)
Graph of inequality x - 2 ≤ 1 is represented by diagram C.
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given inequality
x - 2 ≤ 1
Adding 2 on both sides
x ≤ 3
For x - 2 ≤ 1, value of x should be less or equal to 3
Hence, Diagram C shows the graph of inequality x - 2 ≤ 1.

Explanation: The anglers in a triangle must all add to 180.
Therefore, we can use the equation 180=3x+28+5x+52+2x-10
Combing like terms gives us 180=10x+70
Solving for x gives us 11.
To check our work, we can plug in 11 for x.

which statement correctly compares the function shown on this graph with the function y=6x-1
Answers
Answer:
D.
Step-by-step explanation:
The function shown on the graph is y = 5x - 6 and it is being comapred to y = 6x - 1. The function shown on the graph has a smaller rate of change because 5x < 6x. The starting point of the function shown on the graph is also lower since - 6 < - 1.
The statement correctly compares the function shown on this graph with the function y=6x-1 has a smaller rate of change.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
The function given on the graph is y = 5x - 6 and it is being comapred to the function y = 6x - 1.
Slope intercept form of a line is 5 ...(i)
We have,y = 6x - 1. ...(ii)
On comparing (i) and (ii), we get;
m= 6 , b = -1
