paint the fence in 4 hours. How long would it take if all three students worked together to paint the

Answers

Answer 1

Answer:

4 1/2 hours

Step-by-step explanation:

Pragnesh = 30 minutes

Qazi = 1 1/2 hours

Ronghui = 2 1/2 hours

add them and that gets you 4 1/2 hours. You can also check this yourself by putting this in the number problem. :)

Why is 210 divided by 30 the same as 21 tens divided by 3 tens

Answers

21 tens is equal to 210, and 3 tens is equal to 30.

Reason behind both the situations are the same are the place values of the digits.

What are the place values?

According to their position in a number, each digit has a different value in mathematics, which is called place value. From the unit's starting location, these positions begin.

Ones/units, tens, hundreds, thousands, ten thousands, and so on are all ways to describe the place value of a number's digits in sequence from right to left.

Each digit in a number has a place value, which is its worth. Each digit in a number has a unique value depending on where it sits in the number. The value of a digit depends on where it falls in the number; two comparable digits in the same number may have different values.

When 210 is written in the form of place value, this will be written as 21 tens and 30 will be written as 3 tens.

Therefore, the given statement has the same values and is correct.

The surface area of the net shown is: 88 [tex]in^2[/tex]

Step-by-step explanation:

Break up the different shapes in the net:

Let's take the big square first:

It has a side of 5in and a base of 4in.

We multiply both these values to get 20[tex]in^2[/tex]

Lets look at the small rectangular box now:

It has a side of 3in and a base of 4in.

We multiply both these values to get 12[tex]in^2[/tex]

There are two big squares so we add up their surface areas:

20[tex]in^2[/tex] + 20[tex]in^2[/tex] = 40[tex]in^2[/tex]

There are 4 small rectangular squares so we add up their surface areas:

12[tex]in^2[/tex] + 12[tex]in^2[/tex] + 12[tex]in^2[/tex] + 12[tex]in^2[/tex] = 48[tex]in^2[/tex]

Now we add up the big square and small rectangular squares values:

40[tex]in^2[/tex] + 48[tex]in^2[/tex] = 88[tex]in^2[/tex]

Therefore the answer is 88[tex]in^2[/tex]

Alex bought a new aquarium. He is in the process of setting it up. The aquarium is in the shape of a right rectangular
prism and the dimensions, in inches, are 367 x 19 x 24. During the set-up, Alex fills the aquarium with 6,039
ins of water.
What percent of the volume of the aquarium is filled with water? Round your answer to the nearest whole percent.
Enter your answer in the space provided.

Answers

Answer:

4%

Step-by-step explanation:

Formula for volume of a right rectangular prism is;

V = lwh

Where;

l is length

w is width

h is height

We are given l = 367; w = 24; h = 19

Thus;

Volume is;

V_full = 367 × 24 × 19

V_full = 167352 in³

We are told that Alex filled the aquarium with 6039 in³ of water.

Thus, percentage of the aquarium filled with water is;

(6039/167352) × 100% = 3.61%

Approximating to nearest percent gives; 4%

What is the answer for 4(2p-8)-6p=20+4(p+6)

Answers

Hello! :)

[tex]\large\boxed{p = -38}[/tex]

4(2p - 8) - 6p = 20 + 4(p + 6)

Distribute the coefficients outside of the parenthesis:

4(2p) + 4(-8) - 6p = 20 + 4(p) + 4(6)

8p - 32 - 6p = 20 + 4p + 24

Combine like terms:

2p - 32 = 44 + 4p

Subtract 2p from both sides:

-32 = 44 + 2p

Subtract 44 from both sides:

-76 = 2p

Divide both sides by 2:

p = -38.

Answer p = -4

6p + 2(4 + -2p) = 3(p + 4)

6p + (4 * 2 + -2p * 2) = 3(p + 4)

6p + (8 + -4p) = 3(p + 4)

8 + 6p + -4p = 3(p + 4)

8 + 2p = 3(p + 4)

8 + 2p = 3(4 + p)

8 + 2p = (4 * 3 + p * 3)

8 + 2p = (12 + 3p)

8 + 2p = 12 + 3p

 

8 + 2p + -3p = 12 + 3p + -3p

 

8 + -1p = 12 + 3p + -3p

8 + -1p = 12 + 0

8 + -1p = 12

 

8 + -8 + -1p = 12  

0 + -1p = 12 + -8

-1p = 12 + -8

 

-1p = 4

p = -4

Which equation has a center at (2, 1) and a point on the circle of (2, -3)?
O (x + 2)2 + (y + 1)2 = 16
O x - 2)2 + (y - 1)2 = 4
O(x - 2)2 + (y - 1)2 = 16
O (x + 2)2 + (y + 1)2 = 4

Answers

Answer:

Option 3: [tex](x-2)^2+(y-1)^2 = 16[/tex] is the correct answer

Step-by-step explanation:

We will find the equation of the circle with given information and then compare with the choices given.

Given

Center = (h,k) = (2,1)

And point on circle = (2,-3)

The equation of circle is given as:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

The distance between center and point on circle is the radius. So using the distance formula:

[tex]r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\r = \sqrt{(2-2)^2+(-3-1)^2}\\r = \sqrt{(0)^2+(-4)^2}\\r = \sqrt{0+16}\\r = \sqrt{16}\\or\\r = 4[/tex]

Putting the values in equation of circle

[tex](x-2)^2+(y-1)^2 = 4^2\\(x-2)^2+(y-1)^2 = 16[/tex]

Hence,

Option 3: [tex](x-2)^2+(y-1)^2 = 16[/tex] is the correct answer

The table shows the outputs y, for different inputs ,x

Input x: 3,7,11,15
Output y: 4,6,8,10

Part A: Do the data in this table represent a function? Justify your answer.

Part B: Compare the data in the table with the relation f(x) = 5x-21. Which relation has a greater value when x=11

Part C: Using the relation in part b, what is the value of x if f(x) =99

Answers

Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.

(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.

Part B: All we have to do is plug in 11 for x in the function given to find the answer:

In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.

Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:

There are currently 73 million cars in a certain country, decreasing by 1.7% annually.
How many years will it take for this country to have 54 million cars? Round to the
nearest year.

Answers

Answer:

17.6 years

Step-by-step explanation:

There are currently 73 million cars in a certain country, decreasing by 1.7% annually.

How many years will it take for this country to have 54 million cars? Round to the

nearest year.

We use the formula

y = a(1 - r)^t

a = Initial amount = 73 million cars

y = Future amount = 54 million cars

r = decreasing rate = 1.7 % = 0.017

t = time is unknown

54,000,000 = 73,000,000(1 - 0.017)^t

Divide both sides by 73,000,000

54,000,000/73,000,000 = (0.983)^t

0.7397260274 = (0.983)^t

Take the logarithm of both sides

log 0.7397260274 = Log (0.983)^t

log 0.7397260274 =t log (0.983)

t = log 0.7397260274/log 0.983

t = -0.13092910029/-0.00744648216

t = 17.5826783005 years

Approximately = t = 17.6 years
