Solve for x.

Mathematics
1 answer:
Tems11 [23]3 years ago
4 0

Answer:

x= 21/4

Step-by-step explanation:

1- Convert the expressions

5 ( x - 3 3/4 ) = 7 1/2

2- Remove the parentheses

5 ( x - 15/4 ) = 15/2

3- Move the constant to the right

5x - 75/4 = 15/2

4- Calculate the sum

5x = 15/2 + 75/4

5- Divide both sides

5x = 15/2 + 75/4

The cone and cylinder above have the same radius and height. The volume of the cone is 210 cubic centimeters. What is the
Juli2301 [7.4K]

Answer:

706.3 cm³

Step-by-step explanation:

<u>Given</u>

<em>"The cone and cylinder above have the same radius and height..."</em>

<em>the volume of the cone = 210 cubic centimeters</em>

<u>Formula</u>

The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.

<u>How to solve</u>

Given radius and height calculate the volume, lateral surface area, and total surface area.

Calculate V, L, A | Given r, h

use the formulas above

Given radius and volume calculate the height, lateral surface area, and total surface area.

Calculate h, L, A | Given r, V

h = V / πr2

Given radius and lateral surface area calculate the height, volume, and total surface area.

Calculate h, V, A | Given r, L

h = L/2πr

Given the height and lateral surface area calculate the radius, volume, and total surface area.

Calculate r, V, A | Given h, L

r = L/2πh

Given height and volume calculate the radius, lateral surface area, and total surface area.

Calculate r, L, A | Given h, V

$r = √( V / πh )

Given f(x) =x-7 and g(x) =x2 find g(f(4))
8090 [49]

Answer: g(f(4))=9

Step-by-step explanation:

To find g(f(4)), you first find f(4). Then, you plug it into g(x).

f(4)=4-7            [subtract]

f(4)=-3

Now, we know f(4) into g(x).

g(f(4))=(-3)²      [exponent]

g(f(4))=9

Now, we know that g(f(4))=9.

PLEASE HELP!!!!! 3, 8, 13, 18, 23, ....<br><br> The recursive formula for this sequence is:
rodikova [14]

Answer:

a₈ = 37

Step-by-step explanation:

The given arithmetic sequence is: 3, 8, 13, 18, 23, . . .

The recursive formula for the sequence is: $ a_n = a_{n - 1} + 5 $

Here, $ a_n $ represents the $ n^{th} $ of the sequence.

And, $ a_{n - 1} $ represents the $ (n - 1)^{th} $ of the sequence.

'+5' denotes that '5' is added to the $ (n - 1)^{th} $ term to get the $ n^{th} $ term. In other words, the difference between two consecutive numbers in the sequence is 5.

Now, we are asked to find a₈ i.e., n =8.

Substituting in the recursive formula we get: a₈ = a₍₈₋ ₁₎ + 5 = a₇ + 5.

So, to determine a₈ we need to know a₇. From the sequence we see that a₅ = 23.

⇒ a₆ = 23 + 5 = 28.

⇒ a₇ = 28 + 5 = 32.

⇒ a₈ = 32 + 5 = 37.

Therefore, the $ 8^{th} $ term of the sequence is 37.
