How many cones of radius 1 m and height 1 m have total volume equal to the volume of a sphere with a radius 1m?

DiKsa [7]

Vcone=1/3(hpir^2)
Vsphere=(4/3)pir^3

evaluate
vcone=1/3(1pi1^2)=pi/3
vsphere=4/3pi1^3=4pi/3

pi/3 times what=4pi/3
times both sides by 3
pi times what=4pi
divide both sides by pi
1 times what=4
what=4

4 cones

401 km 101 m – 34 km 153 m

Nikolay [14]

Given :

An expression D = 401 km 101 m – 34 km 153 m.

To Find :

Value of D.

Solution :

We know, 1 km = 1000 m.

So, 401 km 101 m =( 401000 + 101 ) m = 401101 m.

Also, 34 km 153 m = ( 34000 + 153 ) m = 34153 m.

Now, D is given by :

D = 401101 - 34153 m

D = 366948 m

Now, D = 366948 m = 366 km 948 m.

Therefore, the difference is 366 km 948 m.

Hence, this is the required solution.

Write a linear equation that represents the cost of buying t-shirts from Paula's printing. identify the meaning of each variable

g100num [7]

Answer:

Part 1) $y=x+21.5$

Part 2) $y=x+18$

Step-by-step explanation:

Part 1) Write a linear equation that represents the cost of buying t-shirts from Paula's printing.

Let

x ----> the number of t-shirts

y ----> the cost in dollars

step 1

Find the slope

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

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

take two points from the table

(2,23.5) and (4,25.5)

substitute in the formula

$m=\frac{25.5-23.5}{4-2}$

$m=\frac{2}{2}=1$

step 2

Find the equation of the line in point slope form

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

we have

$m=1$

$(x1,y1)=(2,23.5)$

substitute

$y-23.5=(1)(x-2)$

Convert to slope intercept form

$y=mx+b$

$y=x-2+23.5$

$y=x+21.5$

Part 2) Write a linear equation that represents the cost of buying t-shirts from Shantay's shirts.

Let

x ----> the number of t-shirts

y ----> the cost in dollars

step 1

Find the slope

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

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

take two points from the table

(2,20) and (4,22)

substitute in the formula

$m=\frac{22-20}{4-2}$

$m=\frac{2}{2}=1$

step 2

Find the equation of the line in point slope form

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

we have

$m=1$

$(x1,y1)=(2,20)$

substitute

$y-20=(1)(x-2)$

Convert to slope intercept form

$y=mx+b$

$y=x-2+20$

$y=x+18$
