Answers

The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps

For the table

Hi I need help with this problem. But it has to be shown with work. Does anyone know?
x : 6 = 10 : 150

Answers

Answer:

its is 90

Step-by-step explanation:

6x10=60    150-60=90

Answer:

0.4 or 2/5???

Step-by-step explanation:

I believe this is a proportion/ratio problem.

Think of it like this:

x/6 = 10/150

To solve for x, you must cross multiply:

150x = 6*10 (150x... DON'T write 150*x, that is nonsense)

150x = 60

     x = 60/150  (you divide because you are actually dividing 150 on both sides and doing the opposite operation of multiplication)

     x = 6/15

     x = 2/5 or 0.4  (I simplified it)

Hopefully this helped? I can't seem to find a whole number answer... so the only options I could do are 2/5 or 0.4

I have a triangle: Angle A = 3x +28; Angle B = 5x +52; Angle C = 2x - 10: Solve for X

Answers

I have no clue if I even did this right but here’s my work. I don’t wanna get it wrong for you!
Answer: x=11


Explanation: The anglers in a triangle must all add to 180.

Therefore, we can use the equation 180=3x+28+5x+52+2x-10

Combing like terms gives us 180=10x+70

Solving for x gives us 11.

To check our work, we can plug in 11 for x.

3(11)+28+5(11)+52+2(11)-10=180.

2. Now you need to find how many cubes are needed to fill it. Basically since it takes 8 1/2 cm cubes to fill a 1 cm cube, you need to multiply 8 by 13 1/8. I got 105.

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.

Answers

Answer:

yes if each machine makes popcorn for 10 minutes, there be enough popcorn for eight 9-ounce bags

Step-by-step explanation:

yes because 12.74 x 3.3 = 42.075 and 18 x 2.5 = 45 and when you add those together you get 87. Also 8  9-ounce bags = 72 and that is less then what you have.

Answer:

Yes there will be enough popcorn for eight 9-ounce bags.

Step-by-step explanation:

" eight 9-ounce bags"

Basically

"72 ounces"

"12.75 ounces of popcorn in 3 minutes"

Basically

We need to find out how much popcorn we can make in "One Minute"

12.75÷3=4.25

Now we need to find out how much it can make in "Ten Minutes"

4.25×10=42.5

"18 ounces of popcorn in 4 minutes."

Basically:

We wanna find out how much it can make in "One Minute"

18÷4=4.5

"makes popcorn for 10 minutes"

Basically:

We need to find out how much popcorn it can make in "Ten Minutes"

4.5×10=45

Add (45) and (42.5)

45+42.5=87.5

So yes,there will be enough popcorn for eight 9-ounce bangs due to the fact A and B makes (87.5) ounces of popcorn and thats greater than (72) ounces.

Answer:

The answer is 0.045

Step-by-step explanation:

1. Use this formula V=lwh

0.5 x 0.4 x 0.15 = 0.03

That is the volume of the lower prism

2. Do V=lwh again for the volume of the upper prism

0.5 x 0.15 x 0.2 = 0.015

3. After that add both of them up together

0.015 + 0.03 = 0.045
