Solve for the unknown values

Answer:

it litteraly says only 5 points lol. I would help but...

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

x + x + x + 5 + 5 +5 = 27

3x + 15 = 27

  3x  = 27 - 15

  3x = 12

   x = 12/3

x = 4

Answer:

Cylinder volume:

Cylinder surface area:

Find h from the first equation:

Find surface area:

Correct choice is A

Answer:

volume of cylinder=πr²h

785.4=22/7×5²×h

h=785.4×7/(22×25)=9.99=10in

Step-by-step explanation:

surface area of cylinder =2πr(r+h)=2π×5(5+10)=

471.238898038in²

A 471.2in2 is your answer.

Answer:

93°

Step-by-step explanation:

By exterior angle theorem:

(4x + 9)° = 2x° + (3x - 12)°

(4x + 9)° = (2x + 3x - 12)°

(4x + 9)° = (5x - 12)°

4x + 9 = 5x - 12

4x - 5x = - 12 - 9

-x = - 21

x = 21

Measure of exterior angle

= (4x + 9)°

= (4*21 + 9)°

= (84 + 9)°

= 93°

Answer:

C is the correct answer.

Step-by-step explanation:

first look at the first "kite". You got to times 30.5 x 4 ,since all of the sides are equal to each other. If you do the you will get (122).

Now onto the next one. you got to do the same but instead you got to times 40.75 x 2, and you'll come up with (81.5). Then you need to take the other number and do the same. 20.25 x 2, and that will equal to (40.5).

When you get those numbers you need to add them. So, 81.5 + 40.5= 122.

In the end you'll end up with C.

And when they ask for "What did he do wrong?"

He didn't do anything wrong, they are just trying to throw you off.

(If I'm wrong, I'm sorry, you can blame me. )

Answer:

x= −3.5

youre welcome

Answer:

x= -3.5

Step-by-step explanation:  

Step 1: Subtract 2.9 from both sides.  

Step 2: Divide both sides by 0.4.

Answer:

Step-by-step explanation:

(5x+6)+(3x-2) = 180

x = 22

(4y+2) + (3x-2) = 90

(4y+2) + (3·22-2) = 90

y = 6

Four more than the product of 2 and a:

4+2a

Answer:

2a + 4

Step-by-step explanation:

The key word, "product," means you're multiplying, and since it says the "product of 2 and a," you're multiplying 2 and a. To simplify that, you can write 2a (which is equal to 2 · a).

Since it says four more (key word is more), you need to add four to 2a. Since if you have "less than" or "more than", the product will be before the number we're adding, leaving you with  2a + 4.

Answer:

25,118,864,315 J

Step-by-step explanation:

If she is setting up a proportion to find the percent, the value of m would be any variable and the value of n would be 100.  When she solves the problem, m=65%.

13/20 is part out of whole.  The rest of the proportion will be "percent out of 100"; since we don't initially know the percent, we use a variable.  Thus we have

13/20 = m/100

Cross multiply:

20*x = 13*100

20x = 1300

Divide both sides by 20:

20x/20 = 1300/20

x = 65

Answer:

angleF=66

Step-by-step explanation:

F+L=R

F+68=134

F=134-68=66

or

360-68-(180-R)=66

Answer:

5:15

Step-by-step explanation:

Just times both by a random number, I chose 5

So it would be 1x5=5  and  3x5=15

So take those and boom 5:15

Answer:

x + 43 = 72.98

  - 43      -   43

x = 29.98

Step-by-step explanation:

The angles are adjacent because they are next to each other adding to 90 degrees.

How do we find x?

Angle 1 + Angle 2 = 90°

31° + (10x - 1)° = 90°

10x + 30 = 90°

10x = 90° - 30

10x = 60°

x = 60°/10

x = 6

Answer: Adjacent and x = 6.

A, Bread brings the most Income ! (60% of x = 60%x)

B, 20% of the income comes from brownies and cupcakes.

C, 40% comes from others besides bread.

D, If she let go of her 12% from cupcakes, she'd be left with 88%.

If this Is correct, brainliest would be nice. <3 hope this helps.

Answer:

Step-by-step explanation:

Let's just check something out before we continue to fill in the blanks.

The zeros are (x - 1) and (x -5)

y = (x - 1)(x - 5)            Remove the brackets.

y = x^2 - 6x + 5          Complete the square

y = (x^2 - 6x + 9) + 5 - 9

y = (x - 3)^2  - 4

So we have a minumum at (3, - 4)  Now we can go through the rest of the questions.

Part A

(1,0) and (5,0)

Part B

The vertex is (3, - 4) See the completed square above.

Part C

It's a minimum. It is the point between the two roots on the x axis. The vertex drops below the x axis.

Part D

The axis of symmetry goes through the x value of the minimum.

x = 3

The answers are all in parts A B C D. I leave you to figure out where to put them.  You should be able to do that.

Answer:

£17.59

Step-by-step explanation:

100 + 10 = 110% (Price of a ticket after increase)

110% = 19.35

1% = 19.35 ÷ 110 = 0.1759

100% = 0.1759 x 100 = 17.59

Answer:

Step-by-step explanation:

A(1,13), B(5,8)

Let C be 7 units to the right of B:  C(5+7,8) = C(12,8)
