S=2πr^2+πdh solve for h

S = 2πr^2 + πdh

S - 2πr^2 = πdh

(S - 2πr^2) / πd = h

You cannot cancel out the pi on the top and bottom because on the top, it is being subtracted.

Hope this helps!! :)

Jerry was comparing the points the bulls socered for different games he recorded 85,85, 86,77, 93 determine the mean median mode

maks197457 [2]

Answers:
Mean - 85.2
Median - 85
Mode - 85

Explanation:
Mean - 77+85+85+86+93=426/5 (the amount of data points given) = 85.2

Median - Organize the data points from least to greatest and eliminate the outermost numbers two at a time (one from both side) until you’re left with one.

Mode - The number that appears the most often in a given data set

Four times the first number minus three times the second number is 2. Two times the first number increased by three times the se

Eddi Din [679]

Answer:

First number is -2.5

Second number 5

Step-by-step explanation:

Four times the first number minus three times the second number is 2.

To represent this statement, 4x -3y =2

Two times the first number increased by three times the second is 10.

To represent thsi statement, 2x+ 3y = 10

4x - 3y = 2

2x + 3y =10

4x - 2x = 2x

2x = -5

x= -2.5

The first number is -2.5

By using Substitution

2x + 3y = 10

2(-2.5) + 3y = 10

-5 + 3y = 10

3y = 10 +5

3y =15

y = 5

The second number is 5

....To check my answer

-5 + 15 = 10

3. A line goes through the points (3,4) and (-3,6).

Galina-37 [17]

Answer:

Part a) The slope is $m=-\frac{1}{3}$

Part b) The equation in point slope form is $y-4=-\frac{1}{3}(x-3)$

Part c) The equation in slope-intercept form is $y=-\frac{1}{3}x+5$

Step-by-step explanation:

we have the points (3,4) and (-3,6)

Part a) What is the slope of the line?

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given points

$m=\frac{6-4}{-3-3}$

$m=\frac{2}{-6}$

$m=-\frac{1}{3}$

Part b) Write the equation of the line in point-slope form

$y-y1=m(x-x1)$

we have

$m=-\frac{1}{3}$

$point\ (3,4)$

substitute

$y-4=-\frac{1}{3}(x-3)$ ---> equation in point slope form

Part c) Write the equation of the line in slope-intercept form

$y=mx+b$

we have

$y-4=-\frac{1}{3}(x-3)$

Isolate the variable y

distribute right side

$y-4=-\frac{1}{3}x+1$

Adds 4 both sides

$y=-\frac{1}{3}x+1+4$

$y=-\frac{1}{3}x+5$ ---> equation in slope intercept form

What is the slope of the line graph show below?

bonufazy [111]

Answer:

The answer is -2

Step-by-step explanation:

slope formula is m= (y2 -y1)/(x2-x1)

m=(3-1)/(0-1)=

m=2/-1 =

m=-2
