Answer:
A=81.25cm,B=6.5cm
Step-by-step explanation:
P=38cm
L=12.5cm
B=?
P=2(L+B)
P=2L+2B
38=2(12.5)+2B
38=25+2B
C.L.T
2B=38-25
2B=13
divide both sides by 2
B=6.5cm
therefore
A=?
L=12.5cm
B=6.5cm
so,
A=12.5cm×6.5cm
A=12.5×6.5 ×cm×cm
A=81.25×cm²
A=81.25cm²

1. Serena has 1,532 photographs. She has 40 photo albums. Each album holds 36 photographs. Does Serena have enough albums to hold all the photographs?
2. A group of 1,058 people are called in for jury duty. A jury is made up of 12 jurors and 2 alternates. How many complete juries can be formed from the jury pool?
3. Gary's backpack weighs 1.2 pounds. His math textbook weighs 3.75 pounds, and his science textbook weighs 2.85 pounds. How much will his backpack weigh with the math and science textbooks in it?
4. Steven made punch by mixing 2.8 liters of orange juice, 0.75 liters of pineapple juice, and 1.2 liters of sparkling water. How many liters of punch did Steven make?
#1:
Serena does not have enough albums to hold all the photographs.
Work:
40*36 = 1440
#2:
A group of 1,058 people is called in for jury duty.
Work:
A jury is made up of 12 jurors and 2 alternates.
1 jury = 12 jurors + 2 alternates = 14 members
So, the number of complete juries that can be formed is
= 1058/14 = 75.57
#3:
Gary's backpack will weigh 7.8 pounds with the math and science textbooks in it.
Work:
Total weight = backpack weight + math textbook weight + science textbook weight
Total weight = 1.2 + 3.75 + 2.85
Total weight = 7.8 pounds
#4:
Steven made 4.75 liters of punch.
Work:
Liters of Punch = orange juice + pineapple juice + sparkling water
Liters of Punch = 2.8 + 0.75 + 1.2
Liters of Punch = 4.75

How are metric measurement conversions and customary measurements conversions
alike?
Answer: The answer is given below
Step-by-step explanation: How are customary and metric the same?
The metric system uses units such as meter, litre, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces.
The graph represents a relation where x represents the independent variable and y represents the dependent variable. a coordinate plane with points at negative 5 comma 1, negative 3 comma 0, 0 comma negative 3, 2 comma 3, 5 comma negative 1, and 5 comma 1 Is the relation a function? Explain. No, because for each output there is not exactly one input No, because for each input there is not exactly one output Yes, because for each output there is exactly one input Yes, because for each input there is exactly one output
Answer:
To determine whether the relation is a function or not, we need to check if each input value (x) is associated with exactly one output value (y).
Looking at the given set of points (-5, 1), (-3, 0), (0, -3), (2, 3), (5, -1), and (5, 1), we can see that some of the input values are associated with more than one output value. Specifically, the input value of 5 is associated with two different output values: -1 and 1.
Therefore, the relation is not a function because there is not exactly one output value for each input value.
The correct answer is: No, because for each input there is not exactly one output.

Find the missing side of a right triangle if
a. area = 46cm 2 , base = 23cm
b. area = 120cm 2 , base = 40cm
c. area =12m 2 , base = 20m
Grade#8
Answer:
a. The area of a triangle is given by the formula A = (1/2)bh, where b is the base and h is the height. We know that A = 46cm^2 and b = 23cm. Substituting these values into the formula, we get:
46cm^2 = (1/2)(23cm)(h)
Simplifying, we get:
46cm^2 = 11.5cm*h
Dividing both sides by 11.5cm, we get:
h = 4cm
Therefore, the missing side of the right triangle is 4cm.
b. Using the same formula, we can find the height of the triangle:
120cm^2 = (1/2)(40cm)(h)
Simplifying, we get:
120cm^2 = 20cm*h
Dividing both sides by 20cm, we get:
h = 6cm
Therefore, the missing side of the right triangle is 6cm.
c. Again, using the same formula, we can find the height of the triangle:
12m^2 = (1/2)(20m)(h)
Simplifying, we get:
12m^2 = 10m*h
Dividing both sides by 10m, we get:
h = 1.2m
Therefore, the missing side of the right triangle is 1.2m.
can you solve for pi
Answer:
No
Step-by-step explanation:
Pi (π) is a mathematical constant representing the ratio of a circle's circumference to its diameter. It is an irrational number, which means it cannot be expressed as a finite decimal or a fraction. Therefore, it is not possible to solve for pi in the traditional sense.
However, pi can be approximated to a certain number of decimal places using various mathematical methods, such as the Monte Carlo method or numerical integration. The commonly used approximation for pi is 3.14159265358979323846, but the actual value of pi has an infinite number of decimal places and cannot be fully calculated.
Answer:
You can't
Step-by-step explanation:
Pi is already a constant rate if that is what you want to call it. pi is 3.14159265359

This Stem-and-Leaf Graph represents the students’ test scores in History. What is the median for the data in this Stem-and-Leaf plot?
A. 52
B. 59
C. 65
D. 73
Answer:
C. 65
Step-by-step explanation:
The 5 stem has scores of 52, 55, and 57.
The 6 stem has scores of 64, and 66.
The 7 stem has scores of 73, 75, and 79.
Together, the data is: 52, 55, 57, 64, 66, 73, 75, and 79.
The median is the middle number. We can cross out the two outside numbers and go in from there.
52 and 79 are crossed out. 55 and 75 are crossed out. 57 and 73 are crossed out.
When there are two numbers in the middle instead of one (ideally, the one left after this process is the answer), you go between those. Between 64 and 66 is 65.

Question for points :3
The base of a parallelogram is 14 inches, The area of the parallelogram is 98 square inches. Find h the height of the parallelogram.
Answer:
7 inches
Step-by-step explanation:
The formula for the area of a parallelogram is given by A = bh, where A is the area, b is the base, and h is the height.
The parallelogram base is 14 inches, and the area is 98 square inches. Substituting these values into the formula, we get:
98 = 14h
Solving for h, we can divide both sides by 14:
h = 7
Therefore, the height of the parallelogram is 7 inches.
Interquartile range again.... Please help 15 pts.
someone, please help me. I need this done by today. Also, if you do do it, can you write part a and then part B
Answer:
Step-by-step explanation:
Part A: step 1 is correct, step 2 is wrong. Right side of the equation should be 12 - 21 = -9
Part B:
-14x + 21 = 30x + 12
-14x - 30x = 12 - 21
-44x = -9
x = -9/-44 = 9/44
You are buying fruit to make fruit baskets. Apples come in bags of 20. Oranges come in bags of 16 and bananas come in bags of 32.
2. You decide that not only must the fruit baskets be identical, but each one must have the same number of apples, oranges, and bananas.
a. What is the least number of bags of each fruit you need to have the same number of apples, oranges, and bananas? I
b. How many of each type of fruit do you have?
c. There must be at least 5 but no more than 10 of each type of fruit in each basket.
How many different ways can you arrange the fruit baskets when using all of the fruit? Explain your reasoning.
Answer:
You will need to find the least common multiple of 20,16, and 32. The least common multiple of all those will be 160. you will need 8 bags of apples, 10 bags of oranges, and 5 bags of bananas. so for a I believe it would be 8 bags of apples 10 bags of oranges and 5 bags for bananas. as for b it should be 160. and for c you could arrange either 5 of each fruit for 32 baskets, 10 of each for 16 baskets, or 8 of each for 20 baskets

Daksha would like to save at least $500 in 12 months. What is the minimum amount she must save each month in order to save at least $500?
Answer:
$41.67
Step-by-step explanation:
To save at least $500 in 12 months, Daksha must save an average of at least $500/12 = $41.67 per month.
To find the minimum amount she must save each month, we can assume she saves a constant amount each month, and solve for that amount.
Let x be the amount she saves each month. Then over 12 months, she will have saved 12x dollars. To meet her goal of saving at least $500, we need:
12x ≥ 500
Solving for x, we get:
x ≥ 500/12
x ≥ 41.67
Therefore, Daksha must save at least $41.67 each month to save at least $500 in 12 months.
