answer:
104π or 326.56 inches^2
step-by-step explanation:
know the surface area formula for a cylinderonce you know that plug in the numbers givenformula: 2πrh+2πr^2
r stands for radiush stands for heightπ stands for pi- now that you know that, plug in
2πrh+2πr^2
2π(4)(9) + 2π(4)^2
72π + 32π
104π
the answer would be 104π inches^2you can further solve this by multiplying by 3.14 instead of putting πHow many times larger than 2x10^2 is 2x10^8
1000000 times larger
Step-by-step explanation:
2x10^2 is 200.
2x10^8 is 200000000
2x10^8 is 1000000 times larger that 2x10^2

It costs $16 for 8 specialty chocolates for Valentines Day. Find the unit rate 5 per item (how much for 1 chocolate).
Answer:
Unit Rate: 2$ per chocolate
If you're buying 5, it will cost $10
Step-by-step explanation:
Finding the unit rate:
16 ÷ 8 = 2
2 x 5 = $10
If you're talking about what happens if each chocolate cost $5 per item it would be
$5 x 8 chocolates = $40

Answer:
14. 4 + x - 2
15. 8k - 3k
16. 5 + 2y + 15
Step-by-step explanation:
14. "sum" means adding, "minus" means subtract
sum of four and x: 4 + x
minus two: 4 + x - 2
15. "product" means multiplying, "decreased by" means subtract, "times" means multiply
the product of k and 8: 8k
three times k: 3k
the product of k and 8 decreased by three times k: 8k - 3k
(Depending on what the question is asking, you may or may not need to simplify this to 5k (8k - 3k = 5k))
16. "more" means add, "plus" means add, "twice" means multiply by two
five: 5
plus twice y: 5 + 2y
fifteen more: 5 + 2y + 15

Urgent help on math plz
Answer:
x = 14
Step-by-step explanation:
First, organize your work by showing that lines are similar
Line KV is similar to line RV
Line UV is similar to line LV
etc, etc.
=========================================
Now notice that line KV and line RV have the numbers 9 and 18 accordingly
and notice that it's an x2 difference.
==============================================
Now apply the same thing to line UV and LV and divide 26 by 2
That gets us 13
=======================================
Now plug 13 into the equation (2x - 15)
2x - 15 = 13
==========================================
Now solve for X
2x - 15 = 13
Add 15 to each side
2x − 15 + 15 =13 + 15
2x = 28
Divide both sides by 2
2x / 2 = 28 / 2
x = 14
PLEASE HELP IM BEGGING YOU I WILL GIVE BIRRELANSTAST
Answer:
A.)555 in.^2
Step-by-step explanation:
When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.
You can cut that trapezoid into two triangles and one rectangle.
Since both triangles are the same size, you don't need to divide the base and height by two, so you'll get the area of both triangles combined (which saves some work).
We know the length of the rectangle and bases of the triangle combined is 44 inches, and that the length of just the rectangle is 30 inches, so we can just subtract 30 from 44 and divide it by two for the base of a triangle.
44 - 30 = 14
14/2 = 7
Now that we filled in the information not listed, we can finally solve:
The base of one triangle is 7 inches, and the height is 15 inches.
Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).
But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).
7 x 15 = 105
The area of both triangles combined: 105 in.^2
Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).
15 x 30 = 450
The area of the rectangle: 450 in.^2
Now, the final step. Addition. All you need to do is add up all the sums, and you're done.
450 + 105 = 555
The area of entire figure: 555 in.^2
NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)
Solve for x. Do not type degree symbol or any spaces

Answer:
A.
Step-by-step explanation:
Hi there!
By factoring the trinomial, we end with (x-9)(x-4)
However, we aren’t done yet. To find the zeros, set each expression equal to zero, so it looks something like this.
0 = x - 9
0 = x - 4
Using orders of operations, x = 9 and x = 4
Therefore, A is your answer.
I hope this helps!

Answer:
The number is 7
Step-by-step explanation:
let the said number be x
Nineteeen less than 6 times a number;
6x - 19
equals; 16 more than the number; this is 16 + x
Thus;
6x - 19 = 16 + x
6x-x = 16 + 19
5x = 35
x = 35/5
x = 7
