Answer:

Option 3

Step-by-step explanation:

We want to work out the surface-area

This is a cylinder and the formula for the surface area of a cylinder is :

2πrh+2πr^2

^ means to the power of

The radius is 15

The length is 18

2(3.14)(15)(18) + 2(3.14){15}^2

Part 1:

(6.28)(15)(18)

(6.28)(270)

1695.6

Part 2:

First, we do the exponents,

15^2 = 225

(6.28)(225)

1413

Part 3:

1695.6 + 1413 = 3108.6

Answer: 3108.6

Hope this helps :)

Step-by-step explanation:

Answer: What is the question-? :D

Step-by-step explanation:

Answer:

<B = 110°

Step-by-step explanation:

The interior angles formed by the sides of pentagon sum up to 540°.

So <A + <B + <C + <D + <E = 540°

130° + (x - 5)° + (x + 30)° + 75° + (x - 35)° = 540°

3x + 130 + 30 + 75 - 5 - 35 = 540

3x + 195 = 540

3x = 345

x = 115°

<A = 130°

<B = x - 5 = 115 - 5 = 110°

<C = x + 30 = 115 +30 = 145°

<D = 75°

<E = x - 35 = 115 - 35 = 80°

Hope it helps......

Answer:

32 / (10 - 8) / 2 - 3

1/2 * (12 / 2 - 2) + 11

Note: The mention of parentheses makes me believe they are asking for one-line expressions with no fractions. If this is incorrect, replace the slashes with fraction lines with the addition and subtraction outside of said fractions.

Answer:

It's called a Diophantine Equation, and it's sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. One answer is x = 1, y = -1, and z = 2.

Step-by-step explanation:

Answer:

450

Step-by-step explanation:

here is a fast way:

1- 75% = 75/100 = 3/4

2- 600 × (3/4) = 450

Answer:

450

Step-by-step explanation:

Step 1: Convert 75% to fraction

[tex]\frac{75}{100} = \frac{3}{4}[/tex]

[tex]=\frac{3}{4}\times \:600[/tex]

Step 2: Convert 600 to a fraction

[tex]600=\frac{600}{1}[/tex]

Step 3: Set it up

[tex]=\frac{3}{4}\times \frac{600}{1}[/tex]

Step 4: Cross Divide

[tex]600 \div 4 = 150\\3 \div 1 = 3[/tex]

Step 5: Multiply the results

[tex]150 \times 3 = 450[/tex]

Therefore, the machine produced 450 parts yesterday

Everytime your X goes up by 1, your Y goes up by 4

making the space between 6 and 14 = 10

the exponential factor equation would look something like this

g(x)=3^x

meaning every time x goes up by 1, your exponential factor gets multiplied by 3, making 14y have an exponential factor of 1.

Answer:

19x I believe

Step-by-step explanation:

Added 10 and 9, left the x

Answer:

10+9x can't be combined to make a number

Step-by-step explanation:

This is because the 10 doesn't have the variable x so we can't combine them together

If the 10 had an x beside it, it would've become 19x, but it doesn't so it stays as is

Sorry if this is incorrect!!!!!

Bella was here :)

Answer:

I believe the answer is 30 miles per hour.

Step-by-step explanation:

Ok, I may be dangerously very super-duper wrong about this question, but even still, please don't hate me!!!!!!

So to find the constant speed of a moving object you divide distance by the time:

7.5 divided by 1/4 = 1.875

Since this answer doesn't really make since for the question, I decided to change 1/4 to a decimal number, which is 0.25, to see if this makes more since:

7.5 divided be 0.25 = 30

I believe the answer is 30 miles per hour.

Also, I would greatly appreciate brainly if I'm correct!!!!!!!

Have a nice day!!!!!✨

Hopefully this is correct! Good luck

Answer:

not totally sure but I think its C

Answer:

A.

Step-by-step explanation:

Simply put, the line intersects on -2, -4, -6 and 2, 4, 6. So basically, the coordinates match up on each side of the origin.

I rlly hope I helped, good luck :)

Answer:

64

Step-by-step explanation:

length(l)=8cm

breadth(b)=2cm

height(h)=4cm

volume=l×b×h

=8cm×2cm×4cm

=64cm³

Answer:

23.0 ft to nearest 1./0.

Step-by-step explanation:

By Pythagoras:

34^2 = h^2 + 25^2      where h = the height of the building

h^2 = 34^2 - 25^2 = 531

h = 23.04 ft.

Answer:

8953.5 seconds

Step-by-step explanation:

Since the challenger descends at a rate of 4 feet per second, divide 35,814 by 4 to get the answer

Answer:

Hmm i don't know is A B C D

CBA should be hmm 90 degrees I think

Then you should be able to calculate

it's so easy

Step-by-step explanation:

Answer:

D. x = 18; ∠DBC = 54

Step-by-step explanation:

m∠ABD + m∠CBD = 90°

2x + 3x = 90°

5x = 90°

x = 18°

m∠DBC = 3x

m∠DBC = 3(18°)

m∠DMC = 54°

Answer:

80

Step-by-step explanation:

Answer:

4939.22 feet cubed.  

Step-by-step explanation:

The formula for the volume of a cylinder is V=3.14*r^2*h

First we square the raidus, which is 11 in this problem.  11 squared is 121.

Next we multiply everything together.

3.14*121 is 379.94.  Then, 379.94 * the height, which is 13, is 4939.22.

Since our answer is already rounded to the nearest hundredth, the answer to this problem is 4939.22

Answer:x=8 so 60 for both aswers

Step-by-step explanation:10x-7x = 4+20 -> 3x=24 -> x=8

Answer:

x = -4

Step-by-step explanation:

Since P is a straight vertical line, We know that the answer has to be about the x axis

Therefore, since the line is placed on -4 the equation will be

x = -4
