What is the volume of a cylinder with a diameter of 30 cm and a height of 40 cm? Use 3.14 for pie. Round to the nearest 10th.

Answers

Answer 1

Answer:

28,260.0 cm^3

Step-by-step explanation:

The volume of a cylinder uses the equation π[tex]r^{2}[/tex]h.To find the radius, divide the diameter by two, getting r=1/2(30)=15. Plug in all numbers getting:

3.14(15^2)(40)

=3.14(225)(40)

=28260

Answer 2

Answer:

V ≈ 28,260 cm³

Step-by-step explanation:

V = πr²h where,

V = volume

r = radius

h = height

π = 3.14

To find the value of the radius, we take half of the diameter.

1/2(30) = 15

Now that we have all the values, we plug them into the equation and round.

V = (3.14)(15)²(40) = 28,260

V = 28,260

Answer:

1. 795, 23

2. 50, she will finish her candy on November 21 so she won't be able to share with her cousins

3. $276, 71 cars

Step-by-step explanation:

1. your equation: y = 35x + 235

plug in 16 to find how many pictures she will have on may 16: y = 35(16) + 235

you get y = 795

for the second part, you know are trying to find how long it will take to get to 1024 pictures, so you know your y, but you don't know your x

your equation: 1024 = 35x + 235

solve to get x = 22.54

this rounds up to 23, so your answer is 23

2. multiply 8 times 4 to get 32

subtract 32 from 82 to fin how many she has left

you get 50

for the second part, divide 82 by 4 to find how many day it will take to finish her candy

you get 20.5

so no, she will not have candy to share with her cousins, and she will finish her candy on November 21

3. for this, you have a negative y intercept since you need to make $24 to start profiting

your equation: y = 6x - 24

plug in 50 to x: y = 6(50) - 24

you get y = 276

so you make $276 with 50 cars

for the second part, plug in 400 to y: 400 = 6x - 24

solve to get x = 70.66

this rounds up to 71, so your answer is 71

The number of pounds of grapes that are bought will be  [tex]4\frac{29}{40}[/tex]  pounds.

What is fraction?

Fractions are used to represent smaller pieces (or parts) of a whole.

Given the information that Martin bought 12 3/5 pounds of grapes for a picnic, while his friend bought 3/8 of that amount.

Therefore, the amount that his friend bought will be:

= 3/8 × 12 3/5

= 3/8 × 63/5

= 189/40

= [tex]4\frac{29}{40}[/tex]

Hence,  the number of pounds of grapes that are bought will be  [tex]4\frac{29}{40}[/tex]  pounds.

Answers

Answer:

$119, $7.

Step-by-step explanation:

First, we need to find the unit rate of pay, in dollars.

Divide $35 by 5 to get $7 per hour.

Now, we multiply the unit rate of pay by 17 to find out how much money is made in the 17 hours that were worked.

By doing this, we get the answer: $119.

Freida earns $5.25 per hour and time-and-a-half for overtime for all hours over 40 hours. How much did she earn the week she worked 48 hours?

Answers

Answer:

Total earned= $273

Step-by-step explanation:

Giving the following information:

Regular labor hours= $5.25

Overtime labor hours= $5.25*1.5= $7.875

To calculate the total earned, we need to use the following formula:

Regular labor hours= 40*5.25= 210

Overtime labor hours= 8*7.875= 63

Total earned= 210 + 63

Total earned= $273

The track at Bronwyn’s school is ¼ mile around. If she can do 3 laps in 4 ½ minutes,

how fast is she running in miles per hour?

Answers

You start by figuring out how fast a lap is so you do
4.5 (4 1/2 miles)/3
=1.5 minutes

Which means it takes her 1.5 minutes to do 1/4 mile so you times that by four to get how long it takes her to run a mile
4x1.5
=6

This means it takes her 6 minutes to run a mile
To get this into miles per hour you divide 60 (because there’s 60 minutes in an hour) by 6 (her mile time)
60/6
=10

Therefore she is running 10 miles per hour

38 marbles are shared between John, David and Paul so that John gets twice as many as David. Paul gets 5 only. How many marbles does john get?

Answers

Answer:

11

Step-by-step explanation:

The total number of marbles John gets is 22 and this can be determined by forming the linear equation with help of the given data.

Given :

38 marbles are shared between John, David, and Paul so that John gets twice as many as David. Paul gets 5 only.

The following steps can be used in order to determine the total number of marbles john gets:

Step 1 - Let the total number of marbles John have to be 'x', let the total number of marbles David have to be 'y', and let the total number of marbles Paul have to be 'z'.

Step 2 - So, the linear equation that represents the total number of marbles is:

x + y + z = 38    --- (1)

Step 3 - According to the given data, John gets twice as many as David, that is:

x = 2y  --- (2)

Step 4 - According to the given data, Paul gets only 5 marbles, that is:

z = 5  --- (3)

Step 5 - Substitute the value of x and z in equation (1).

2y + y + 5 = 38

Simplify the above equation.

3y + 5 = 38

3y = 33

y = 11

Step 6 - Substitute the value of y in equation (2).

x = 2(11)

x = 22

So, the total number of marbles John gets is 22.

Synthetic division is very useful for determining roots of polynomials.  Once we have roots, we can easily write the corresponding factors.  

Write out possible factors of 6:  {±1, ±2, ±3, ±6}

Let's determine whether or not -2 is a root.  Set up synthetic division as follows:

-2   /   1   -2   -5   6

              -2     8   -6

     -----------------------

        1     -4      3    0

since the remainder is zero, we know for sure that -2 is a root and (x + 2) is a factor of the given polynomial.  The coefficients of the product of the remaining two factors are {1, -4, 3}.  This trinomial factors easily into {(x -1), (x - 3)}.

Thus, the three factors of the given polynomial are {(x + 2), (x - 1), (x - 3)}

Step-by-step explanation:

There are two ways to solve this question.

Way Number 1

60 is 20% of the total students

20÷100= 0.2

60÷0.2=300

Therefore there are 300 students

Way Number 2

60 is 20% of the total students

60/20 = x/100

x= 60*100÷20

x= 6000÷20

x= 300

Therefore there are 300 students.

2.Use at least 2-3 sentences to explain how to find the measure of an interior angle of a triangle when you are given the other two angle measures.

Answers

Answer:

Step-by-step explanation:

1). By definition of an exterior angle of a triangle,

  Measure of exterior angle of a triangle is equal to the sum of opposite two interior angles.

  From the figure attached,

  m∠4 = m∠1 + m∠2

2). Property of a triangle states that " sum of interior angles of a triangle is 180°"

   Therefore, m∠1 + m∠2 + m∠3 = 180°
