Find the perimeter and area.

a. Rectangle, L=14m and B=9.5m
b. Square, side=14.5cm
c. Rectangle, L=25cm and B=16.8cm

Grade#8

Answers

Answer:

Therefore, the perimeter and area of the given shapes are:

a. Perimeter = 47m, Area = 133m²
b. Perimeter = 58cm, Area = 210.25cm²
c. Perimeter = 83.6cm, Area = 420cm²

Step by step solved:

a. To find the perimeter of a rectangle with length L=14m and breadth B=9.5m, we use the formula:

Perimeter = 2(L+B)

Plugging in the values, we get:

Perimeter = 2(14m + 9.5m) = 2(23.5m) = 47m

To find the area of the rectangle, we use the formula:

Area = L x B

Plugging in the values, we get:

Area = 14m x 9.5m = 133m²

b. To find the perimeter of a square with side length=14.5cm, we use the formula:

Perimeter = 4 x side

Plugging in the value, we get:

Perimeter = 4 x 14.5cm = 58cm

To find the area of the square, we use the formula:

Area = side²

Plugging in the value, we get:

Area = 14.5cm x 14.5cm = 210.25cm²

c. To find the perimeter of a rectangle with length L=25cm and breadth B=16.8cm, we use the formula:

Perimeter = 2(L+B)

Plugging in the values, we get:

Perimeter = 2(25cm + 16.8cm) = 2(41.8cm) = 83.6cm

To find the area of the rectangle, we use the formula:

Area = L x B

Plugging in the values, we get:

Area = 25cm x 16.8cm = 420cm²

Answer:

Step-by-step explanation:

rectangle Perimeter = 2(l+b)

So, 2(14+9.5)

=> 46.5m

area = lb

So, 14*9.5

=> 133m^2

Square Perimeter = 14.5*4

= 58cm

Area = 14.5^2

= 210.25m^2

Rectangle #2

2(25+16.8)

=> 83.6 cm

Area = 420m^2

What is 5/6 of 14 1/2?

PLEASE explain how it is!

please help its last question and i been on it for 15 minutes

Answers

Answer:

5/6 of 14 1/2 is 12.08333333

Step-by-step explanation:

14 1/2 = 14.5

14 = 14

and 1/2 = 0.5

now, you take 14.5 and divide by the denominator of the fraction that you have, which is 6

14.5 ÷ 6 = 2.416666667

and now you take 2.416666667 and multiply that by 5, because you are trying to find 5/6 of this number

2.416666667 × 5 = 12.08333333

So your answer is 12.08333333

It’s 12 1/12.
You basically just multiply 5/6 and 14 1/2 which is 145/12 and that simplified is 12 1/12

Doira has a company that sells plants. She sells 34 for plants for $9,000 each her first day. The next couple days she sells 34 for $99,999 each. If she keeps selling them for $99,999 each for 100 weeks,how many plants will she have sold? How much money will she have made?

Answers

Answer:

1)23,800 plants.

2)$2,380,068,200

Step-by-step explanation:

1) if Doira sells 34 plants for $99,999 each for 100 weeks, she will have sold a total of 23,800 plants.

2.On the first day, Doira sold 34 plants for $9,000 each, so she made a total of 34 x $9,000 = $306,000.

In the following days, she sold 34 plants for $99,999 each, so her daily earnings were 34 x $99,999 = $3,399,966.

If she continues to sell 34 plants for $99,999 each for 100 weeks, she will sell a total of 34 x 100 x 7 = 23,800 plants.

Her total earnings from selling 34 plants for $99,999 each for 100 weeks will be 23,800 x $99,999 = $2,379,762,200.

Adding her earnings from the first day, her total earnings will be $2,379,762,200 + $306,000 = $2,380,068,200.

Answer: she would sell 340 plants and make $9,999,900

Step-by-step explanation:

34 x 100 =340

99, 999 x 100 = 9,999,900

From a log of wood of length (8x+12) m, a piece of length (4x+3) m was cut. Find the length of the remaining log of wood.


Grade#7

Answers

Answer: 4x+9

Step-by-step explanation: (8x+12)- (4x+3)

Answer: (4x+9)

Step-by-step explanation:

Log of wood = (8x+12)

piece length = (4x+3)

So, (8x+12) - (4x+3)

=> (8x+12) - 4x - 3

=> 8x-4x +12 -3

=> 4x + 9

So, the length of the remaining piece of wood = (4x+9)

Answer:

198

Step-by-step explanation:

length =11

width=18

Length times width = area

11 times 18 equals 198

i hope this helps! <3

Page 1, Answer:
168 cm

Explanation:

First we should find the area of the non-shaded parts

Length: 5cm
Width: 4cm
5x4=20
1st square= 20 cm

Length: 5cm
Width: 2cm
5x2= 10
2nd square= 10 cm

Now we add:
20+10=30

Shaded part:
11x18=198

We have to subtract the shaded part by the non shaded part:
198-30=168

Answer= 168cm


Page 2:

Answer 1:
Both are equal

Explanation:

Both are equal because:

16+4=20
A=20cm

B: 5+5+5+5
5x4=20
B=20 cm

Answer 2:
16

Explanation:

Since we are already given the product we need to find the factors, square has 4 equal sides so we have to divide by 4:

64/4=16
Ans=16cm

Answer 3:
62cm

Explanation:
We need to divide the shape into 2.

Rectangle 1:
10+5+?+?

Since we already know what one side is it will be the same on the other side:

10+10+5+5
20+10=30

Rectangle 1=30cm

Rectangle 2:

Here we start to add and subtract:

Length: 10-5=5

Width: 6+5=11

5+5+11+11
10+22=32
32 cm

Total:
Now that we know both perimeters we add:

32+30=62

Total=62cm

This means that if two lines ____ at (−6,4), then (−6,4) is the ____ to the system of equations.

This means that if you substitute −6 for x and 4 for y in the equations, both equations will be ____.

Answers

Answer:

The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.

If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).

This means that if two lines intersect at (−6,4), then (−6,4) is the solution to the system of equations.

This means that if you substitute −6 for x and 4 for y in the equations, both equations will be true. However, this information alone is not enough to determine whether a system of linear equations has a solution just by looking at the graph of the equations

I Got You Bro

The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.

If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).

What is Coordinate Geometry?

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.

If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).

This means that if two lines intersect at (−6,4), then (−6,4) is the solution to the system of equations.

This means that if you substitute −6 for x and 4 for y in the equations, both equations will be true.

However, this information alone is not enough to determine whether a system of linear equations has a solution just by looking at the graph of the equations

Hence, the coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.

Answers

From my understanding and your lack of a picture:

The triangle CAT has rotated in 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.

Step-by-step explanation:

From the given figure it is noticed that the coordinates of the vertices of the pre-image are C(-2,1), A(-3,3) and T(1,1). The coordinates of the vertices of the image are C'(1,2), A'(3,3) and T(1,-1).

From these coordinates, we can conclude that the relation between the preimage and image is

If a figure rotated 90 degrees clockwise direction about the origin, then

Therefore triangle CAT is rotated 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.

A. The cooler is meant to be used by only 24 players.

B. Before practice, there are 648 ounces of sports drink in the cooler.

C. If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink.

Answers

Answer:

Step-by-step explanation:

ounces of sports drink in the cooler.

C. Each player is expected to drink 24 ounces of sports drink during practice.

D. If no players take drinks from the cooler, there will be 648 ounces of sports drink in the cooler after practice.

Statement B is true: Before practice, there are 648 ounces of sports drink in the cooler, as the y-intercept of the equation is 648.

Statement C is not true: The coefficient of x, -24, does not represent the amount of sports drink each player is expected to drink. It represents the rate at which the amount of sports drink in the cooler decreases as players take drinks.

Statement D is not true: If no players take drinks from the cooler, x would be 0, and the amount of sports drink in the cooler after practice would be y = -24(0) + 648 = 648. However, this situation is not realistic, as players would normally take drinks from the cooler during practice.

Statement A is not true: The equation does not limit the number of players who can use the cooler. The equation only models the rate at which the amount of sports drink in the cooler decreases as players take drinks.

B.
In mx+b, b is initial value meaning they started with 648 ounces
