THIS QUESTION DOESNT MAKE ANY SENSE TO ME SO IF YOU KNOW OR COULD HELP PLEASE DOA cone-shaped kitchen funnel has a diameter of 6 inches and a height of 7 inches. About how many times would you need to fill the funnel to fill a cylindrical can that has a radius of 4 inches and a height of 13 inches?

A. 3

B. 4

C. 9

D. 10

Answer 1

Answer:

Answer:

The funnel will fill the container in about 10 times

Step-by-step explanation:

To solve this question, the principal thing to do is to calculate the volumes of the cone-shaped funnel and the cylinder to actually know the number of times we will need to fill the funnel so as to fill the cylinder,

These number of times can simply be calculated by dividing the volume of the cylinder by the volume of the cone-shaped funnel.

Mathematically, we proceed as follows;

Volume of the cone funnel = 1/3 ×π× $r^(2)$ × h, where r and h represents the radius and height of the cone respectively.

From the question D = 6 inches, and mathematically r = D/2 = 6/2 = 3 inches and h = 7 inches

Plugging the values we have in the question, the volume = 1/3 ×π× $3^(2)$ ×7 = 21π $inches^(3)$

For the cylindrical receptacle, we have the volume calculated as π× $r^(2)$ × h

Where r = 4 inches and h = 13 inches.

Plugging these values we have ; π × $4^(2)$ × 13 = 208π $inches^(3)$

Now the number of times is simply = volume of cylindrical container/volume of cone-shaped funnel

= 208π/21π = 208/21 = 9.9 which is approximately 10 times

Multiply and simplify the product.(8 – 5i)2
Select the product.

a. 39

b. 89

c. 39-80i

d. 89-80i

Answers

Simplifying the square of a complex binomial is done similarly to a purely real binomial, except that one was to remember the relation i² = -1.

Solving the equation (8 – 5i)² is done below:

Rewriting (8 – 5i)²:

(8 - 5i)(8 - 5i) = 64 - 40i - 40i + 25i²

Simplifying and applying i² = -1:
64 - 80i + 25(-1)
64 - 80i - 25
39 - 80i

From the choices, the answer is C.

Answer:

39 – 80i

a gasoline pump delivers 4 2/5 gallons of gas per minute. how many minutes will it take to fill a gas tank that holds 16 1/2 gallons?

Answers

The number of minutes will it take to fill a gas tank that holds $16(1)/(2)$ gallons is $3 (3)/(4)$ .

Given that, a gasoline pump delivers $4 (2)/(5)$ gallons of gas per minute.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

A gas tank that holds $16(1)/(2)$ gallons

Time taken to fill the gas tank

= $16(1)/(2) / 4(2)/(5)$

= 33/2 ÷ 22/5

= 33/2 × 5/22

= 3/2 × 5/2

= 15/4

= $3 (3)/(4)$

Therefore, the number of minutes will it take to fill a gas tank that holds $16(1)/(2)$ gallons is $3 (3)/(4)$ .

B is the midpoint of AC and D is the midpoint of CE solve for x given BD = 3x+4 and AE = 5x+19

Answers

It might be helpful to draw a diagram of a line in this case, but you could do this algebraically as well. The midpoint of any segment is basically the average of the two endpoints of the segment. Thus, for example, the midpoint of AC would be the value of A added to the value of C, which is then divided by 2 to get B. You just have to find all of the values for each of the letters, and then find the distance between B and D, for instance, which (the distance) may be represented as a system of equations with the statement of the distance for AE.
