Answer:

volume = 415800

Surface Area inside = 26370

Step-by-step explanation:

slowly added up all sides for surface area.

volume is area of trapezoid side (b1 + b2 divided by 2 multiply by height) x bottom length (70)

trapezoid Area = 106 + 34 +40 Divided by 2 then multiply by 66

The volume of the wheelbarrow is 415800 cubic centimeter.

What is Area?

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -

V = ∫∫F(x, y) dx dy

Given is a wheelbarrow that is used to carry wet concrete. The dimensions tray are provided in the image.

We can write the volume of the wheelbarrow as -

V = {(1/2 x 34 x 66) + (66 x 40) + (1/2 x 66 x 66)} x 70

V = {1122 + 2640 + 2178} x 70

V= 415800 cubic centimeter.

Therefore, the volume of the wheelbarrow is 415800 cubic centimeter.

Cost of the student ticket to the school play is $7. Write an equation that correctly relates the total cost, c,

Answers

Complete question :

The cost of a student ticket to the school play is $7. Write an equation that correctly relates the total cost, c, for a particular number, s, of student tickets purchased. Identify the independent and dependent variable.

Answer:

Dependent variable = Total cost

Independent variable = number of students

Step-by-step explanation:

The total cost equation is :

Total cost, c = cost per ticket * number of tickets

c = 7 * s

c = 7s

The Independent variable also called the predictor variable is the number of students in the scenario described above as it is the variable upon which the total cost relies. It dictates the value of the output or dependent variable. As we vary the value of the Independent variable, number of students, the total cost which is the dependent variable also varies. The dependent variable on the other hand is the predicted value or variable which is controlled by the independent variable. The dependent variable in this case is the total cost, c

Talia bought home. For her pet turtle. The rectangular tank is 3 feet lonc,1 foot wide, and 2 feet high. What is the volume of the tank

Answers

Answer: 6ft³

Step-by-step explanation:

The tank described is a rectangular tank which means that it is a rectangular cube.

The volume of a rectangular cube is calculated by multiplying the length by the width by the height.

Volume of tank is:

= Length * Width * height

= 3 * 1 * 2

= 6 ft³

A. 6 cm
B. 8 cm
C. 10 cm
D. 14 cm
please show how you got the answer!​

Answers

Answer:

C. 10cm

Step-by-step explanation:

First we can rearrange the equation to solve for length (l):

V = lwh

Divide both sides by wh:

l = V/(wh)

Substitute in known values:

l = 1200/(15x8)

l = 1200/120

l = 10cm

What is the volume of a rectangular prism that has a height of 2 inches a width of 2 and 1/2 inches and a length of 5 and 1/2 inches?

Answers

Answer:

V = 27.4 in^2

Step-by-step explanation:

Converting to mixed numbers with fractions in decimal format makes this problem easier.  2 1/2 inches is the same as 2.5 inches; 5 1/2 inches is 5.5 inches.

The volume formula is V = L*W*H.

Here, V = (5.5 in)(2.5 in)(2 in), or 27.4 in^2

A school ordered 32 orange shirts, 29 blue shirts, and 34 green shirts. The shirts are being divided equally among 6 classrooms. If each classroom gets the same number of shirts, how many shirts will be left over?
A.
2
B.
4
C.
5
D.
3

Answers

Answer: D

Step-to-step explanation:

Answer:

C

Step-by-step explanation:

The orange shirts will have 32/6 = 5 with 2 left over

The blue shirts will have 29/6 = 4 with 5 left over

The green shirts will have 34/6 = 5 with 4 left over

The left overs are 2 + 5 + 4 = 11 but I have divided the colors equally. If color does not matter then the total number of shirts = 32 + 29  + 34

The total number of shirts is 95

95/6 = 15 with a remainder of 5

So 5 shirts will be left over.

Answer:

Sorry, I can't help you with that :( I hope someone else can tho!

Step-by-step explanation:

Is this correct?? Please dont mine the little notes I took when solving it..

A= 12, base= 16

Area= (1/2)(12)(16) = 96

384+96 =480

Semi Circle should be something like =(1/2) pir^2

diameter= hypotenuse= sqrt(12^2 +16^2) = 20

radius= r= d/2= 20/2

Semi Circle= (1/2) pi 10^2= 50pi= 157.0796327

Total = 480+157.0796327=637.0796327. Rounding to the nearest hundred would give me 637.08??

Answers

Answer and Step-by-step explanation:

Yes, all of your calculations are correct!!

The area of one rectangle is 192, and since there are 2 rectangles, we multiply 192 by 2, which results in 384.

The area of a triangle is [tex]A = \frac{(Height)(Base)}{2}[/tex], which you got to be 96.

The Semi Circle would have half of the area of a circle, so you are correct when you multiply the equation by [tex]\frac{1}{2}[/tex].

To find that diameter, we need to use the Pythagorean Theorem.

[tex]12^{2} + 16^{2} = d^{2} \\\\144 + 256 = d^{2} \\\\400 = d^2\\\\d = 20[/tex]

So the diameter is 20, and the radius is 10 (20 divided by 2 = radius).

Plug that into the equation, and you get the answer to be [tex]50\pi[/tex], or 157.0796327.

157.0796327 + 384 + 96 = 637.08 (rounded to the nearest hundredth).
