Please help and explain please. would appreciate it!

Step-by-step explanation:

part 1

Area =2L×2B

2(9in) ×2(6in)

18in×12in

=216in²

Part 2

Area of a triangle =½×base ×height

½×9in×14in

=63cm²

5 is what percent of 25? = 20

1/4 x^2 + 11 = 38

multiply both sides by 4

x^2 + 44 = 152

x^× = 152 - 44

x^2 = 108

x = + or - 6 square root of 3

x¹ = -6 square root of 3

x² = +6 square root of 3

Answer:

n = 50

Step-by-step explanation:

The sum of interior angles of a regular polygon is 24 times the size of exterior angle. Find number of sides of the polygon​

let the sum of exterior be e

Let the sum of interior be i

IF the sum of interior angles of a regular polygon is 24 times the size of exterior angle, then;

i = 24e

Also sum of exterior angle = 360/n

i + e = 180

24e + e = 180

25e = 180

e = 180/25

e = 7.2

since  sum of exterior angle = 360/n

7.2 = 360/n

n = 360/7.2

n = 50

The number of sides is 50

Answer:

12

Step-by-step explanation:

The required length of the triangular prism is given as 15 centimeters.

Given that,
The volume of a triangular prism is 30 cm. Each triangular face has an area of 4 cm, how long the prism is to be determined.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The volume of the triangular prism = 1 / 2[area of face] × length
                                               30  = 1/2 [4] × length
                                          length = 15 cm

Thus, the required length of the triangular prism is given as 15 centimeters.

Answer:

  $11,988

Step-by-step explanation:

A graphing calculator gives you the answer easily.

The minimum unit cost is $11,988.

__

The equation for unit cost can be put into vertex form to find the minimum.

  C(x) = 0.7x^2 -210x +27738

  C(x) = 0.7(x^2 -300x +150^2) +27738 -0.7(150^2)

  C(x) = 0.7(x -150)^2 -11,988

This is vertex form:

  C(x) = a(x -h)^2 +k . . . . . . . where (h, k) is the vertex.

The vertex of this cost function is (150, 11,988).

The minimum unit cost occurs when 150 engines are produced. That unit cost is $11,988.

Answer:

the answer is $11,988

Step-by-step explanation:

Given: [tex]f(x)=4x-2[/tex]

To find:  average rate of change of the function [tex]f(x)=4x-2[/tex] over the interval [tex]x=-1[/tex] and [tex]x=2[/tex]

Solution:

Take [tex]a=-1,\,b=2[/tex]

Find [tex]f(a),\,f(b)[/tex]

[tex]f(a)=f(-1)\\=4(-1)-2\\=-4-2\\=-6\\\\f(b)=f(2)\\=4(2)-2\\=8-2\\=6[/tex]

Average rate of change of the function [tex]=\frac{f(b)-f(a)}{b-a}[/tex]

[tex]=\frac{f(2)-f(-1)}{2-(-1)}\\\\=\frac{6-(-6)}{3} \\\\=\frac{12}{3}\\\\=4[/tex]

Answer:

madision be $12

Jasmine be $24

And, the devanie be $18

Step-by-step explanation:

The computation is shown below:

Madison be x

Jasmine be 2x

Devanie be x + 6

And, the total is $54

Now the equation is

x + 2x + x + 6 = $54

4x = $48

x = $12

So madision be $12

Jasmine be $24

And, the devanie be $18

Step-by-step explanation:

Given:

The price of a doll = $35

Sales tax = 6%

To find:

The tax amount that a customer will pay on one doll.

Solution:

The price of doll is $35 and the sales tax is 6%, so the tax amount on a doll is 6% of 35.

[tex]\text{Tax amount}=35\times \dfrac{6}{100}[/tex]

[tex]\text{Tax amount}=\dfrac{210}{100}[/tex]

[tex]\text{Tax amount}=\dfrac{21}{10}[/tex]

[tex]\text{Tax amount}=2.1[/tex]

Therefore, the tax amount that a customer will pay on one doll is $2.1.
