Help!!A restaurant uses a container that is shaped like a right triangular prism to package carry out sandwich orders. A net of the container is shown below. What is the surface area? I need this question ASAP!! Thanks

Answers

Answer 1

Answer:

145.9 square inches is the surface area of the container.

Split the container as per the given picture,

Area of rectangle 1 with dimension 8 by 3 = 24

Area of rectangle 2 with dimension 11.3 by 3 = 33.9

Area of a triangle with dimension 8 by 8 = 1/2*8*8 = 32

Thus,

Surface area of the container = 2*Area rectangle 1 + 2*area of the triangle + Area of the rectangle 2

Surface area of the container = 2 * 24 + 2 * 32 + 33.9

The surface area of the container = 145.9 in²

Therefore, the surface area of the given container is 145.9 square inches.

Which equation represents the law of sines for triangle abc?

Answers

Answer:

See below.

Step-by-step explanation:

The equation is:

a / sin A = b / sin B = c / sin C

- where A, B and C are the 3 angles in the triangle and a, b and c are the sides opposite these angles respectively.

Answer:

a/sinA = b/sinB = c/sinC

A striped marlin can swim at a rate of 70 miles per hour. Is this a faster or slower rate than a sailfish, which takes 30 minutes to swim 40 miles? Show your work.

Answers

Let's do the work shall we....

this is going to be a ratio problem.

Striped Marlin:
70 miles/ One hour (Or 60 minutes)

Sailfish:
40 miles/ 30 minutes.

Since 30 minutes is only one half of 60 minutes, all we have to do is multiply the sailfish ratio by 2 in order to receive the correct mph.

(40miles/30 minutes) x2 = (80 miles/60 minutes(or one hour)).

Therefore, the sailfish is faster! 80 miles per hour is faster than the 70 mph marlin.

You convert the minutes to hours and the marlin is slower because 70 mph is less than 80 mph.My work is in the attachment.

Five more than twie the number is 17

Answers

I assume you meant: Five more than twice the number is 17.
If so, you're going to set up your equation as: 17 = 2x+5
17 being the total, 2x being "twice the number", and +5 being "five more than".
Now, subtract 5 from both sides of the equation.
You have 12 = 2x
Then, divide by 2.
You get 6 = x.

Hey, Edwin7311!

Is means equal sign

More means addition

Twice means times 2.

5+2x=17

Subtract 5 from each side.

5+2x-5=17-5

2x=12

Divide 2 from each side.

x=6

I hope this helps;)

Knitting: You are knitting a blanket. You want the area of the blanket to be 24ft^2. You want the length of the blanket to be 2 feet longer than the width. What should the dimensions of the blanket be?

Answers

You can use factors to solve. Determine all the factor pairs of 24, find the two that are two numbers apart.
1, 24 X
2, 12 X
3, 8 X
4, 6 YES!

Algebraic way to solve using Quadratics:
l = 2 + w

A = lw

A = (2 + w)w Substitute (2 + w) for l

24 = (2 + w)w Substitute 24 in for the area

24 = 2w + w^2 Distribute

w^2 + 2w - 24 = 0 Set equal to 0 (put in standard form)

(w + 6) (w - 4) = 0 Factor

w + 6 = 0 and w - 4 = 0 Set each factor equal to 0.

So w= -6 or w = 4 ... -6 makes no sense for a length! So the width must be 4 and the length will be 4 + 2, which is 6.
