A triangular prism is 12.7 yards long. It has a triangular face with a base of 19 yards. The volume of the prism is 1,894.205 cubic yards. What is the height of its triangular face?

Answers

Answer: I don’t know

What is the volume of this composite solid?

Answers

For cases like these, we need to find the base then multiply it by the height. Let’s separate the triangle and the rectangle of the base

Triangle:

1/2(6*9) = 27

Rectangle:

5 * 9 = 45

Total base:

45+ 27 = 72

Now for the area:

72 * 12 = 864 m^3

864 m^3 would be the volume.

If the crane operator works 30 years and the train engineer works 33 years, who makes the most lifetime income? How much more?

Crane Operater|| Annual salary : 54,830|| Years of Education: 4
Train engineer|| Annual salary : 50,610 || Years of Education: 6

Answers

Answer:

The train eingineer.

Step-by-step explanation:

So, to find the lifetime income, we must multiply the annual income by the years of work.

So for the cran operator:

54,830*30

1,644,900

Now lets compare this to the train eingineer:

50,610*33

1,670,130

So looking at the two numbers:

1,670,130(train eingineer)>1,644,900(crane operator)

So the trian eignineer makes more than the crane operator.

Now lets find the amount.

To do this, lets subtract the larger value by the smaller value:

1,670,130-1,644,900

25,230

So the train eingineer made 25,230 more dollars than the crane operator.

Hope this helps!

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he
has 7 chairs left over. If he arranges the chairs in 4 rows of that same length, he has 13 left over. How many
chairs does Liam have?

Answers

We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.

This sets up a problem of:

6x + 7 = 4x + 13

7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.

x = 3

Knowing this, we plug in x for one of the equations

6(3) + 7
18 + 7
25

Liam has 25 chairs.

Step-by-step explanation:

possibly Chondro malacia

Damage to the cartilage under the kneecap.

Symptoms may include

Knee pain

Cracking joints

Swelling of the knee

Please go to your doctor...ik it hard with cov id and everything

It could be hereditary, or it could just be a weak muscle. I have knee problems. If it’s just your knee cap that is dislocating you can do simple exercises to strengthen the muscle around it to hold it in place. If it’s your actual knee you should get it checked out to see if there is anything else going on. If it continues and there’s nothing “wrong” they’ll have you do physical therapy. When this dislocation happens, keep your knee up above your heart and ice it. After you pop it back on. And take pain relief. Wear a knee brace as well

Factor the simplified expression using
the GCF.

Part C
What is the value of the expression
when b = 2 and c = -3?

Answers

Answer:

Part A) − 12 b + 6 c + 18

Part B) -2b + 1c + 3

Part C) -4

Step-by-step explanation:

Part A)

Step 1:

-4b + -8b = -12b

Step 2:

8c + 2c = 6c

Step 3:

12 + 6 = 18

Answer: − 12 b + 6 c + 18

Part B)

GCF = 6

Step 1:

-12 divided by 6 = -2b

Step 2:

6 divided by 6 = 1c

Step 3:

18 divide by 6 = 3

Answer: -2b + 1c + 3

Part C)

Step 1: Subsitute 2 for b and 3 for c

(− 2 x 2 ) + (1 x -3) + 3

Step 2: Multiply (− 2 x 2 ) + (1 x -3) + 3

-4 + (-3) + 3

Step 2: Add -4 + (-3) + 3
