Answer: a is the right answer

Step-by-step explanation:

Given:

A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13.

To find:

The total surface area of the prism.

Solution:

We have,

Height of prism = 7½ = 7.5

Sides of triangular base are 5, 12, 13. These sides of Pythagorean triplets because

[tex]5^2+12^2=13^2[/tex]

[tex]25+144=169[/tex]

[tex]169=169[/tex]

So, the base of the prism is a right triangle.

Area of a triangle is

[tex]Area=\dfrac{1}{2}\times base \times height[/tex]

[tex]A_1=\dfrac{1}{2}\times 5\times 12[/tex]

[tex]A_1=30[/tex]

The area of the base is equal to the area of the top, i.e., [tex]A_2=30[/tex] sq units.

Perimeter of the base is

[tex]P=5+12+13[/tex]

[tex]P=30[/tex]

The curved surface area of the prism is

[tex]CSA=\text{Perimeter of the base}\times \text{Height of the prism}[/tex]

[tex]CSA=30\times 7.5[/tex]

[tex]CSA=225[/tex]

Now, the total area of the prism is

[tex]A=A_1+A_2+CSA[/tex]

[tex]A=30+30+225[/tex]

[tex]A=285[/tex]

Therefore, the total surface area of the triangular prism is 285 square units.

Answer:

5x - 8

Hope it helped :)

Answer:

5x-8

Step-by-step explanation:

im assuming you mean 20x^2 instead of 20x2 bc when you copy and paste it usually gets rid of the "^".

the area of a rectangle is length*width

so, to find the width, we have to solve the equation (4x+1)*width=20x^2-27x-8

the goal is to find (20x^2-27x-8)/(4x+1)

there is many ways to solve this: long division, synthetic division (easiest way)

but I'll just do guess and check

we know that the answer is in the form ax+b

we also know that b*1=-8 bc that's just how foiling works

We also know 4a=20

so, the answer is 5x-8

obviously you can check this answer if you are unsure of it being correct

(4x+1)(5x-8) = 20x^2-32x+5x-8 = 20x^2 - 27x - 8

so it does work

17.5 = √6² + w²

17.5² = 36 + w²

306.25 = 36 + w²

270.25 = w²

√270.25 = w

16.4392822 = W

=  w = 16.44 in

The given question is incomplete. The complete question is:

Joanna earns $12 per hour at her job. Last week, joanna earns $432

use this information to answer the next question. Which equation can be used to determine the number of hours Joanna worked last week.

a. h+ 12 = 432

b. 432 h =12

c. 12 h = 432

d. [tex]\frac{1}{12} h=432[/tex]

Answer: c. 12 h = 432

Step-by-step explanation:

Given : Amount paid per hour = 12 $

12 $ are earned by Joanna by working for = 1 hour

Thus 432 $ are earned by Joanna by working for = [tex]\frac{1}{12}\times 432hour=36hours[/tex]

Thus the equation that can be used to determine the number of hours Joanna worked last week is [tex]12\times h=432[/tex]

Answer:

The area of the shaded portion is 450.185 in^2

Step-by-step explanation:

21^2+20^2=841

The square root of 841 is 29

29+20+21=70

70*1/2=35

35-29=6

35-21=14

35-20=15

The square root of 35*6*14*14=210

The area of the triangle is 210 in^2

The diameter of the circle is 29, so the radius is 14.5

14.25^2=210.25

210.25*3.14=660.185

660.185-210=450.185

Answer:

225.08, which would just be 225.

Step-by-step explanation:

First, you multiply the percent, 17, times the total number of points, 1,324, which you should get 22,508. Then, divide that by 100, and you will get your answer 225.08. The reason you put it into the whole number, is because you can't score part of a point, so you always round down even if the number is in favor to round up. I hope this helps :)

So r=21 because 21/3=7    

Answer

$128

Step-by-step explanation:

Okay well if $80 is 100% then 60% is 48 dollars.

so 80 +48=128

Answer: 882

Step-by-step explanation:

75% is the same as 3/4.

You would divide the total number of customers 1176 by 4 to find 1/4 then times by 3 to find 3/4 or 75%.

1176 divided by 4 = 294

294 times 3 = 882

Answer:

A'B' = 7.5

Step-by-step explanation:

uhhh

AC = A'C'

4 = 6

×1.5

AB^2 = 4^2 + 3^2

AB^2 = 16 + 9

AB^2 = 25

AB = √25

AB = 5

A'B' = 5 × 1.5 = 7.5

The value of A'B' for the given congruent triangle will be 7.5.

If two figures are exactly the same in sense of their side of all things then they will be congruent.

If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.

As per the given congruent triangle,

In triangle ABC,

AB = √(3² + 4²) = 5

The ratio of the corresponding sides of the two triangles is the same.

A'B'/A'C' = AB/AC

A'B'/6 = 5/4

A'B' = 30/4 = 7.5

Hence "The value of A'B' for the given congruent triangle will be 7.5".

Answer:

x = 1, y = 4, or x = -2, y = 1

Step-by-step explanation:

y = -x^2 + 5

-x + y = 3

Use substitution to solve for the equation

-x + (-x^2 + 5) = 3

-x^2 - x + 5 = 3 (simplifying)

-x^2 -x  + 2 = 0 (simplifying)

(-x + 1)(x+2) = 0 (factoring)

-x + 1 = 0 or x + 2 = 0

x = 1, or x = -2

-x + y = 3

-(1) + y = 3, or -(-2) + y = 3

y = 4, or y =  1

just choose any one...

x = 1, y = 4

or x = -2, y = 1

(they both work)
