Answer: Common ratio, r = (3/2)/(3/20) = 10.

3/20, 3/2, 15,

4th term = 15*10 = 150

5th term = 150*10 = 1500

5th term = 1500

3/20, 3/2, 15,

4th term = 15*10 = 150

5th term = 150*10 = 1500

5th term = 1500

What is the surface of a cylinder that has a height of 8 and a radius of 10

ANSWER

square units.

EXPLANATION

The given cylinder has a height of 8 and a radius of 10.

The formula for calculating the surface area of a cylinder is

We substitute r=8 and h=10 into the formula to get:

Or using π=3.14

units square.

Answer:

Surface area I'm guessing. 1,130.4

Step-by-step explanation:

The formula for the surface area of a cylinder is: 2*pi*r^2 + 2*pi*r*h.

Plug in the values given.

2*pi*10^2 + 2*pi*10*8

628 + 502.4 = 1,130.4

(If you want the most precise value, use a calculator for pi instead of just 3.14.)

An aquarium holding African cichlids is 4 inches higher than it is wide. Its length is 30 inches, and its volume is 4200 cubic inches. What is the length and width?

H = w + 4 ;

V = h × w × l ;

Then, 4200 = ( w + 4 ) × w × 30 ;

4200 ÷ 30 = ( w + 4 ) × w ;

140 = ( w + 4 ) × w ;

w^2 + 4w - 140 = 0 ;

For ax^2 + bx + c = 0, the value of x is given by: ;

In our case, a = 1 ; b = 4 ; c = - 140

Roots are - 14 and 10 ;

The correct answer is w = 10inches because w > 0 ;

Finally, h = 14 inches .

V = h × w × l ;

Then, 4200 = ( w + 4 ) × w × 30 ;

4200 ÷ 30 = ( w + 4 ) × w ;

140 = ( w + 4 ) × w ;

w^2 + 4w - 140 = 0 ;

For ax^2 + bx + c = 0, the value of x is given by: ;

In our case, a = 1 ; b = 4 ; c = - 140

Roots are - 14 and 10 ;

The correct answer is w = 10inches because w > 0 ;

Finally, h = 14 inches .

What is the correct classification of 23x + 16? A. monomial B. binomial C. trinomial

Answer: B. binomial.

Step-by-step explanation:

1. You can classify polynomials based on the number of terms the polynomial has:

- If it has one term is classified as a monomial.

- If it has two term is classified as a binomial.

- If it has three terms is classified as a trinomial.

2. The polynomial has two terms. Therefore, the correct clasification is: binomial.

3. Then, the correct answer is the option B.

Answer:

B. binomial

Step-by-step explanation:

23x+13 has two terms so it is a binomial

1 term is a monomial

3 terms is a trinomial
