Answer:

B

Step-by-step explanation:

Theoretically it is 120/8=15

Answer:

b= 7

Step-by-step explanation:

here's your solution

=> perimeter of rectangle = 62 cm

=> length = 24 cm

=> let width be (b)

=> perimeter of rectangle = 2(l + b)

=> 2(l + b ) = 62

=> 2(24 + b) = 62

=> 48 +2b = 62

=> 2b = 62 - 48

=> 2b = 14

=> b = 14/2

=> b = 7

Answer:

102cm³

Step-by-step explanation:

Imagine the shape as two rectangular prisms, a small one on top of a bigger one. Find their volumes individually, and then add them together:

Small rectangular prism

Volume=length*width*depth

=2*3*(7-5)

=6*2

=12cm³

Bigger rectangular prism

Volume=length*width*depth

=6*3*5

=6*15

=90cm³

12+90=102cm³

Answer:

mean: 14.64

mode: 15

median: 15

range:   15

outliers: 25

Answer:

Step-by-step explanation:

let the points scored by a girl=x

points scored by a boy=y

7x+2y=46

7x-2y=38

add

14x=84

x=84/14=6

7×6+2y=46

2y=46-42=4

y=4/2=2

girl scored =6 points

boy scored=2 points.

Answer:

→ Mean of given data = xi = (86 + 49 + 63 + 90 + 82 + 98 + 36) / 7 = 504 / 7 = 72 .

→ variance of the set of data = 525

Step-by-step explanation:

Hope it is helpful....

Answer:

525

Step-by-step explanation:

(86 + 49 + 63 + 90 + 82 + 98 + 36) / 7 = 504 / 7 = 72 . → variance of the set of data = 525

Answer:

(0, 4 ) and (2, - 4 )

Step-by-step explanation:

(2)

3x + 4y = 16 → (1)

- 3x + 2y = 8 → (2)

Adding (1) and (2) term by term will eliminate the x- term

0 + 6y = 24

6y = 24 ( divide both sides by 6 )

y = 4

Substitute y = 4 into either of the 2 equations and solve for x

Substituting into (1)

3x + 4(4) = 16

3x + 16 = 16 ( subtract 16 from both sides )

3x = 0 , then

x = 0

solution is (0, 4 )

(3)

2x - 4y = 20 → (1)

5x + 4y = - 6 → (2)

Adding (1) and (2) term by term will eliminate the y- term

7x + 0 = 14

7x = 14 ( divide both sides by 7 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (2)

5(2) + 4y = - 6

10 + 4y = - 6 ( subtract 10 from both sides )

4y = - 16 ( divide both sides by 4 )

y = - 4

solution is (2, - 4 )

Answer:

a. Base area, B= 24 square units.

b. Volume, V = 96 cubic units.

Step-by-step explanation:

Given the following data;

Length of sides = 4 units

Width of sides = 6 units

Height = 4 units

a. To find the base area, B;

The base of a rectangular prism is a rectangle.

Area of rectangle, B = length * width

Area of rectangle, B = 4 * 6

Area of rectangle, B = 24 square units.

b. To find the volume;

Volume of rectangular prism = base area * height

Volume= 24 * 4

Volume = 96 cubic units.

Answer:

B = 24 square units.

V = 96 cubic units.

khan academy hint.

Answer:

The answer is D because it is closer to zero so it is greater in value. For example if the number is further away from zero (and is negative) the value is less but if it’s closer it is greater and in positive numbers the rules are opposite

Step-by-step explanation:

Answer:

The maximum height attained by the ball is of 180 feet.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, y_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

Where

[tex]\Delta = b^2-4ac[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].

In this question:

We have that:

[tex]s(t) = -16t^2 + 48t + 144[/tex]

Which is a quadratic equation with [tex]a = -16, b = 48, c = 144[/tex].

The maximum height is the value of s, which is the output, at the vertex. So

[tex]\Delta = b^2-4ac = 48^2 - 4(-16)(144) = 11520[/tex]

[tex]s_{v} = -\frac{11520}{4(-16)} = \frac{11520}{64} = 180[/tex]

The maximum height attained by the ball is of 180 feet.

Answer:

$ 1100

Step-by-step explanation:

Let p(x) be the price he charges for a car after x price reductions.

Since car costs him $10,000, and fixed costs are $1000

p(x) = 13000-10000-1000-300x = 2000 - 300x

Let  q(x) = 12 + 2x the quantity of cars sold after x price reductions.

and the profit he can make are given by:

Profit = R(x) = (12+2x)(13,000 - 10,000 - 1,000 - 300x) dollars.

As you can see, maximizing profit , we have to check where P'(x) = 0

And P''(x)<0.

So we get x = 3.

Replacing the value we get we get 2000 - 300 X 3 = 2000 - 900

                                                                 = $ 1100

Answer:

P-E-M-D-A-S

Step-by-step explanation:

Ok, so start with what i call "P-E-M-D-A-S"

P: parentheses | Also known as these: ( )

E: exponents | Its a small number by another number, like the 3 on your screen

M: Multiply | Also Known as   x or a dot

D: Divide | i forgot how to make it

A: Add | also known as +

S: Subtract | also known as -

now go in order to solve it, it makes it much more easy!

Answer:

49 is your answer

Step-by-step explanation:

let's do b-pemdas

brackets

parentheses

e(I forgot the name for it but it's basically a small number next to the big number)

Multiply

Divide

Add

Subtract

you do the equation in that order

so

2+8•7-(3^2)

we focus on (3^2)

that's 3•3 which equals to 9

so now the equation is

2+8•7-9

Now we focus on 8•7 which equals to 56

the equation now looks like

2+56-9

you then add 56 to 2 which equals to 58 and then subtract 9 from it so it should look like this

2+56=58

58-9= 49

and 49 is your answer
