write a function rule for the volume of the cylinder with a hight 3 inches more than 4 times the radius of the cylinders base. w

Licemer1 [7]

$\text { The function rule is volume }=\pi \times \text { radius' }^{2} \times(3+4 \times \text { radius) and Volume }=44 \pi \text { when radius }=2$

<u>SOLUTION: </u>

Given that, we have to write a function rule for the volume of the cylinder with a height 3 inches more than 4 times the radius of the cylinders base. And the volume of the cylinder when it has a radius of 2 inches

Now, let us write the function rule.

We are given that, height 3 inches more than 4 times the radius of the cylinders base

$\begin{array}{l}{\rightarrow \text { Height }=3 \text { inches }+4 \text { times radius of cylinders base. }} \\\\ {\rightarrow \text { Height }=3+4 \times \text { radius. }}\end{array}$

Then, $\text { volume }=\pi \times \text { radius' }^{2}\times \text { height } \rightarrow \text { volume }=\pi \times \text { radius }^{2} \times(3+4 \times\text { radius) }$

So we have written the function rule.

Let us find volume when radius = 2.

$\begin{array}{l}{\text { Then, volume }=\pi \times 2^{2} \times(3+4 \times 2)} \\\\ {\Rightarrow \pi \times 4 \times(3+8)=\pi \times 4 \times 11=44 \pi}\end{array}$

the diameter of a bicycle wheel is 0.7 meters. find the number of complete revolutions made by the wheel if the bicycle travels

larisa [96]

Answer:

$200\ rev$

Step-by-step explanation:

we know that

$1\ rev=2\pi r$ ----> circumference of a circle

step 1

Find the circumference of a circle

The circumference is equal to

$C=2\pi r$

we have

$r=0.7/2=0.35\ m$ ----> the radius is half the diameter

$\pi=22/7$

substitute

$C=2(22/7)(0.35)=2.2\ m$

step 2

Find the number of complete revolutions made by the wheel if the bicycle travels 440 meters

Divide the total distance by the circumference

$\frac{440}{2.2}=200\ rev$

Jason has decided to sell one of his baseball cards. The card is valued at $51.00. The store is only offering Jason $29.00. How

sveta [45]

Well, just take the difference, 51-29, and 22 is how much less his card it being valued at. Or you can do 29-55, which would be -22, showing the amount and that it's valued less.

The equation 15x + 30y = 180 represents the number of children x and adults y who can attend the rodeo for $180. Find the x- and

ICE Princess25 [194]

We want to find the x and y-intercepts for the given linear equation.

The x-intercept is x = 12, and the y-intercept is y = 6.

We know that x represents the number of children and y the number of adults that can attend the rodeo for $180.

The x-intercept is defined as the x-value when y = 0. So we just need to replace y by 0 and solve for x:

15*x + 30*0 = 180

15*x = 180

x = 180/15 = 12

Meaning that if there are no adults, 12 children can attend to the rodeo for $180.

The y-intercept is the y-value when x = 0, similarly to before, this is computed as:

15*0 + 30*y = 180

30*y = 180

y = 180/30 = 6

This means that if only adults go, 6 of them can go for $180.

Mickey and Donald earn $53 weekend after taxes Mickeys share is seven dollars greater than Donald's how much does Donald earn ea

igor_vitrenko [27]

Donald earns $23 each weekend and Mickey earns $30.

Step-by-step explanation:

Given,

Money earned by Mickey and Donald = $53

Let,

Share of Mickey = x

Share of Donald = y

According to given statement;

x+y=53 Eqn 1

x = y+7 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(y+7)+y=53\\y+7+y=53\\2y=53-7\\2y=46$

Dividing both sides by 2

$\frac{2y}{2}=\frac{46}{2}\\y=23$

Putting y=23 in Eqn 2

$x=23+7\\x=30$

Donald earns $23 each weekend and Mickey earns $30.
