The perimetre of a rectangle is 38cm length is 12.5, What is the Area?...

Answers

Answer 1

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

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.

Answers

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

Answers

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

Answers

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.

The base of a parallelogram is 14 inches, The area of the parallelogram is 98 square inches. Find h the height of the parallelogram.

Answers

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.

divide both sides by 14 and h=7

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

Answers

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.

Answer:

a. h = 8cm
b. h = 12cm
c. h = 2.4m

Step by step explanation :

To find the missing side of a right triangle, we need to use the formula for the area of a triangle, which is:

Area = (1/2) x base x height

where base is one of the sides of the triangle, and height is the length of the perpendicular drawn to that base.

a. Given that the area of the triangle is 46cm² and the base is 23cm, we can find the height as follows:

46cm² = (1/2) x 23cm x height

Simplifying the equation, we get:

height = (2 x 46cm²) / 23cm

height = 4cm x 2 = 8cm

Therefore, the missing side of the right triangle is 8cm.

b. Given that the area of the triangle is 120cm² and the base is 40cm, we can find the height as follows:

120cm² = (1/2) x 40cm x height

Simplifying the equation, we get:

height = (2 x 120cm²) / 40cm

height = 6cm x 2 = 12cm

Therefore, the missing side of the right triangle is 12cm.

c. Given that the area of the triangle is 12m² and the base is 20m, we can find the height as follows:

12m² = (1/2) x 20m x height

Simplifying the equation, we get:

height = (2 x 12m²) / 20m

height = 1.2m x 2 = 2.4m

Therefore, the missing side of the right triangle is 2.4m.

Martin used a coordinate plane to design the garden shown. Each unit on the grid represents 10 yards.

How many square yards will the garden be after it is built? What is the total AREA of the garden?

Answers

The best way to solve this is to break the shape up into areas you know how to solve.

Lets divide this into the big rectangle being separated from the smaller rectangle at the bottom.

To find the height of the big rectangle, subtract one y-coord of 30 from the other y-coord 80.

80-30=50

To find the length of the big rectangle, subtract one x-coord of 10 from the other x-coord of 100.

100-10= 90

Multiply these to get the area of the big rectangle:

90 x 50 = 4500 units squared

Next, find the smaller recatngle’s area by repeating the previous steps:

Height: 30-10 = 20
Length: 70-40 = 30

Now find the area:

20 x 30 = 600 units squared

Finally, add both of these areas up to find the total area for the original shape:

4500 + 600 = 5100 units squared

Hope this helped!

can you solve for pi

Answers

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.

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?

Answers

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.

Answers

#1:

Serena does not have enough albums to hold all the photographs.

Work:

#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

#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.
