3. There are 6645 students at Tech Middle School, and
20% of the stredents are 7th graders.
How
many
Students are 7th graders?

Answers

Answer 1

Answer:

.20

Step-by-step explanation:

The word percent literally means "Out of 100". With that being said, 20% can be written as a fraction, mixed number or whole number as follows: 1/5 (fraction), 20/100 (mixed number) or .20 (whole number).

Answer 2

Answer:

1329 students

Step-by-step explanation:

20/100 ×6645

Reduce the fraction 20/100 with 20

So..20 goes into 20 1 time and 20 into 100 5 times

1/5×6645

Use 5 as the greatest common factor now

so...5 into 5 goes 1 time and 5 into 6645 goes 1329

1/1 × 1329 = 1329

Or... you could just convert 20% into a decimal by carring the . two places to the left

which is 0.2

0.2 × 6645 = 1329

A) It is a uniform probability model because each color has an equal chance of being selected. B) It is a non-uniform probability model because each color has an equal chance of being selected. C) It is a uniform probability model because each color does not have an equal chance of being selected.

Answer:

B it is a non-uniform probability model because each color has an equal chance of being selected

Step-by-step explanation:

Developing a uniform probability model by assigning equal probability to all. If we select one student at random from the ten, is that a uniform then student name or grade level or color of their shirt or shoe size or different that the probability model uniform is different so that means the model is a non-uniform

Answer:

h = 3 cm

Step-by-step explanation:

The volume (V) of a rectangular prism is calculated as

V = Ah ( A is the area of the base and h the height )

Here V = 36 and A = 6 × 2 = 12 cm² , then

12h = 36 ( divide both sides by 12 )

h = 3

Answer: 3 cm

Step-by-step explanation:

The formula to solve the volume of a rectangular prism is V = l x w x h

Where V is volume, l is length, w is width, and h is height

Givens are, Volume = 36 cm3

length = 6 cm

width = 2 cm

Now, we will plug in the numbers to the formula

36 cm3 = 6cm x 2cm x h

36 cm3 = 12 cm2 x h

divide 12cm2 on both sides

36cm3/12cm3 = h

h = 3cm

The length of a rectangular garden is 5 meters more than its width. If the
area of the rectangular garden is 150 m2, identify the equation used to find
the width of the rectangular garden.

O W(W+5) = 150
O W(W + 5) 22 = 150
O 1/2(2W + W) = 150
O 2W(W + 5) = 150

Answers

Answer:

Width of rectangular garden = 10 meter

Step-by-step explanation:

Given;

Area of rectangle garden = 150 m²

Length of rectangular garden = 5 meters more than its width

Find:

Width of rectangular garden

Computation:

Assume;

Width of rectangular garden = W

So,

Length of rectangular garden = 5 + W

Area of rectangle garden = length x width

(W)(W + 5) = 150

W² + 5W = 150

W² + 5W - 150 = 0

W² + 15W - 10W  - 150 = 0

W(W + 15) - 10(W + 15) = 0

(W + 15)(W - 10)

So,

W = -15, W = 10

Width of rectangular garden = 10 meter

The answer to the question is C

The perimeter of ABCD is 26 cm

The area of PQRS is 45 cm(squares)
Find the length of AB

Answers

Area of rectangle= LxW
45cm2 divided by 10cm = 4.5cm
B-C= 4.5cm
Perimeter of rectangle= L+W x2
26/2 =13cm -4.5= 8.5cm
QR = 10cm and the area of that rectangle is 45cmsq so to work out PQ you do 45/10 = 4.5cm
PQ= 4.5cm

As BC = PQ they both equal 4.5cm

and the perimeter of ABCD is 26cm you so 26- (4.5x2) = 17
and 17/2 = 8.5cm

AB is 8.5cm

Answer:

Step-by-step explanation:

To find the volume of the surface area of a cone, we need to use the height and not the slant height of the cone

The slant height, the height and the base radius forms a right triangle with the slant height being the hypotenuse of this triangle

By Pythagoras’ theorem, the square of the hypotenuse (slant height) equals the sum of the squares of the two other sides

6.5^2 = 2.5^2 + h^2

h^2 = 36

h = √36

h = 6 cm

So we have the volume as;

V = 1/3 * pi * r^2 * h

where r in this case is base radius of 2.5 cm

V = 1/3 * pi * 2.5^2 * 6 = 39.3 cm^3
