Which expression will give the correct volume of the cylinder?

Answer:

x=69

Step-by-step explanation:

when you add the side lengths you have, you will get 21. since this is a right triangle, yoy subtract by 90. so 90-21 = 69

Answer:

Answer:

( 5, -10)

Step-by-step explanation:

Answer: 12.5

Step-by-step explanation:

He made 50 dollars in 4 weeks so divide that equally amongst each week you get 12.5

The rate of change of money in his savings account per week is 12.5

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

We have, After 4 weeks, he had $350 dollars and after 9 weeks, he had

$412.50.

So, We can consider it as (4, 350) and (9, 412.5)

So, the rate of change is

=(412.5-350)/ (9-4)

= 62.5

= 12.5

Hence, the rate of change is 12.5.

Answer:

slope: 4/3

Midpoint: (2,-2)

distance : 20

Step-by-step explanation:

you can find the slop by m=y2-y1/x2-x1

m= 6-(-10)/8-(-4)   m=4/3

use the midpoint formula: (x₁ + x₂)/2, (y₁ + y₂)/2 and we get (2,-2)

distance formula- [tex]\sqrt{(x2-x1)+(y2-y1)[/tex]

the distance is the square root of 400 which is 20

Answer:

[tex]y=-0.4x+8[/tex]

Step-by-step explanation:

Let the Linear Function to represent the drip of water out of the water tank be:

[tex]y=mx+c[/tex]

Where [tex]x[/tex] is the time

[tex]y[/tex] is the number of gallons at that time

[tex]m[/tex] is the rate at which water drips

[tex]c[/tex] is the initial number of gallons of water in the tank

Putting the given values in the above equation:

[tex]6.8 = m\times 3+c ..... (1)[/tex]

[tex]4.4 =m\times 9+c..... (2)[/tex]

Subtracting (1) from (2):

[tex]6m=-2.4\\\Rightarrow m =-0.4[/tex]

Putting in equation (1):

[tex]6.8=-0.4\times 3+c\\\Rightarrow c = 8[/tex]

Therefore, the linear function equation to represent in the situation is:

[tex]y=-0.4x+8[/tex]

Answer: QT

Step-by-step explanation: This is because line QT is a straight line, in which it leads from point Q to line RS. QT is true because any other lines have angles, which add more (inaccurate) distance.

The required representation of distance from point Q to RS is QT.

A line is a straight distance connecting two points or more showing the shortest distance between the initial and final points.

here,
A figure is shown with a line segment RS and a point is located some distance from line RS, denoted as Q. It is to be determined which represents the distance from point Q to RS.

The shortest distance between a point and a line is the perpendicular line drawn from the point to the line, so QT is the representation of the measure of the distance from point Q to RS.

Thus, the required representation of distance from point Q to RS is QT.

Answer:

2,907 pieces of bowtie noodles was used by the student

Step-by-step explanation:

Here, we want to calculate the number of pieces of bowtie noodles use

Let the number of elbow noodles used be x

The number of bow tie noodles used is 9 times this and that will be 9 * x = 9x

Adding both together, we have 9x + x = 10x

Thus;

10x = 3230

x = 3230/10

x = 323 pieces

The number of pieces of bowtie noodles used will be 323 * 9 = 2,907 pieces

Answer:

46 seconds

Step-by-step explanation:

Brylee has hiked 125 feet and hikes 1 foot per second.

125 + s

Jeremiah has hiked 10 feet and hikes 3.5 feet per second.

10 + 3.5s

Where

s = number of seconds

Equate both Brylee and Jeremiah expression

125 + s = 10 + 3.5s

Collect like terms

125 - 10 = 3.5s - s

115 = 2.5s

Divide both sides by 2.5

s = 115 / 2.5

= 46

s = 46 seconds

Answer:

bruh really its 5

Step-by-step explanation:

Answer: 20 years

Step-by-step explanation:

Principal = $2000

Rate = 5%

Interest = $2000

Time = Unknown

Since we want to know the time it will take his money to double, that means he'll have an interest of $2000.

Interest= PRT/100

2000 = (2000 × 5 × T)/100

2000 = 10000T/100

Cross multiply

2000 × 100 = 10000T

200,000 = 10000T

T = 200,000/10,000

Time = 20 years

The answer is x=26

Step-by-step explanation:

8x-71=5x+7 (because they are congruent you make them equal each other)

Add 71 to both sides

8x=5x+78

subtract 5x

3x=78

divide 3 from both sides

x=26
