Answer 2

Answer:

Area of two rooms is 357 square feet

Length of the baseboards = 89.5 ft

Step-by-step explanation:

Area and perimeter of rectangular room:

Area of the room = length * width

Area of the two rooms = area of bigger room + area of smaller room

                                       = 19 * 15 + 8 * 9

                                        = 285 + 72

                                        = 357 square feet

To find the length of the baseboard, we need to subtract the width of the opening (5 feet) and width of the entry (2 1/2 feet) from the perimeter of the bigger room and subtract the width of the opening (5 feet) from the perimeter of the smaller room.

Bigger room:

length = 19 ft

Width = 15 ft

Width of the entry =  2 1/2 ft = 2.5 ft

Width of the opening between two rooms = 5 ft

Perimeter of bigger room = 2l + 2w - 5 - 2.5

                                          = 2*19 + 2*15 - 7.5

                                          = 38 + 30 - 7.5

                                           = 60.5 ft

Smaller room:

length =  8ft

Width = 9 ft

Width of the opening = 5 ft

Perimeter of the smaller room = 2*8 + 2*9 - 5

                                                   = 16 + 18 - 5

                                                   = 29 ft

Length of the base board = 60.5 + 29

                                           = 89.5 ft

A musician kept track of the concert arenas on this year's tour and found that 60% of the arenas were sold out. Of those that were not sold out, 25% had been on the previous tour schedule from last year, while 90% of those that were sold out were on the previous tour schedule. Which of the following represents the joint relative frequency of arenas that were sold out and not on the previous tour schedule?

75%
54%
30%
6%

Answers

Answer:

6%

Step-by-step explanation:

First, let's break this down:

60% of arenas sold out

90% had been on previous tour

Out of those arenas that did NOT sell out

25% had been on previous tour

We want to know the joint relative frequency of area that were sold out AND NOT on the previous tour schedule, therefore all the information about areas that did NOT sell out is irrelevant.

Because 90% of the areas that were sold out had been on the previous tour, 10% had NOT been on the previous tour.

Therefore, considering all the arenas, 10% of 60% of the arenas were sold out and not on the previous tour.

Let x equal the total number of arenas:

[tex](.10)(.60)x=0.06x[/tex]

Convert to percent

6%

Therefore, the joint relative frequency of sold out arenas that were not on the previous tour is 6%.

In a discount clothing​ store, all sweaters are sold at one fixed price and all shirts are sold at another fixed price. If one sweater and four shirts cost ​$47​, while four sweaters and three shirts cost ​$84​, find the price of one sweater and the price of one shirt.

Answers

Answer:

Step-by-step explanation:

Let x be the sweater

Let y be the shirt

Equation1:    x+4y=47

Equation2:    4x+3y=84

Now solve for x in the first equation:

x+4y=47

x=47-4y

Now that we've solved for x, substitute the value for x which is 47-4y into Equation2 as follows:

4x+3y=84

4(47-4y)+3y= 84

188-16y+3y= 84

188-13y= 84

-13y= 84-188

-13y= -104

y= -104/-13

y= 8

Now plug in the value for y which is 8 into Equation 1 and solve for x:

x+4y=47

x+4(8)=47

x+32=47

x=47-32

x=15

You can perform a check by plugging in the x and y values into equations 1 and 2 which should yield true statements.

The answer is: 1 sweater costs $15 and 1 shirt costs $8

Colin is borrowing money from his parents to purchase a $700
computer. He will pay them $35 per month for two years. Determine the
simple interest rate on Colin's loan.

Answers

Colin paid the loan at a ten percent annual interest rate.

Simple interest is the form of interest calculation in which the principal amount remains the same for the entire duration for which the loan is taken.

It is also assumed that Colin will repay $35 per month for the next two years.

We must calculate a simple interest rate on Colin's borrowings.

As a result, Colin's total payment to his parents for two years is $35.

We are required to find simple interest rate on Colin's borrowings

Therefore, total amount paid by Colin to his parents= 35$ for 2 years

        =35*24=840

The amount paid by Colin is principal + interest

Thus, the simple interest amount= 840-700=140$

We know that the simple interest formula is principal*rate*time/100.

We know that the simple interest is 140, the principal is 700, the time is two years, and we need to find the rate of interest.

SI= P*R*T/100

140= 700*R*2/100

140/7*2=R

R=140/14=10

Therefore, The Rate of interest on which Colin paid the loan is 10 per cent per annum

A customer paid a total of $6.00 for 68 copies at a print shop. Some of the copies were black-and-white copies, and the rest were color copies.



• Each black-and-white copy cost $0.08.
• Each color copy cost $0.15.



How many copies of b, the number of black-and-white, and c, the number of color did the customer pay for?

Answers

The number of black-and-white is 60 and the number of color copies is 8.

How to calculate the value?

Let b = the number of black-and-white.

Let c = the number of color copies.

The equation will be:

b + c = 68

0.08b + 0.15c = 6

Multiply equation I by 0.08

Multiply equation ii by 1.

0.08c + 0.08c = 5.44

0.08b + 0.15c = 6

Subtract

0.07c = 0.56

c = 0.56/0.07

c = 8

Since b + c =68

b= 68 - 8 = 60

Therefore, the number of black-and-white is 60 and the number of color copies is 8.

11 ft
7 ft 8 ft
20 ft What is the area of the shape?

Answers

Answer:

Area = 192.5 ft.²

Step-by-step explanation:

By splitting the shape in 2, we can find the area much simpler.

Starting with the parallelogram (on the left), the area formula is A = b × h.

b (base) = 11 ft.

h (height) = 7 ft.

A (area) = (11 ft.)(7 ft.)

A = 77 ft.² (save this for later)

Then, the trapezoid's (on the right) area formula is A = [(a + b) ÷ 2] × h.

a (first base) = 8 ft.

b (second base) = (20 - 7) = 13 ft.

h (height) = 11 ft.

A = [(8 ft. + 13 ft.) ÷ 2] × 11 ft.

A = [(21 ft.) ÷ 2] × 11 ft.

A = (10.5 ft.) × 11 ft.

A = 115.5 ft.²

Now, bringing back the first area, we can add them together to find the total:

A = 77 ft.² + 115.5 ft.²

A = 192.5 ft.²

How many gallons of a 50% antifreeze solution must be mixed with 70 gallons of Strength
25% antifreeze to get a mixture that is 40% antifreeze? Use the six-step method.

Answers

The number of gallons that must be needed to antifreeze 50% solution is 105.

Given that 50% antifreeze solution must be mixed with 70 gallons of Strength 25% antifreeze to get a mixture that is 40% antifreeze.

The six-step method involves a few steps that need to perform. These are defining the problem, determining the root cause, finding the alternative solution to solve the problem, selecting the solution, implementing the solution, and finally evaluating the outcome.

Let's consider x be the number of gallons of a 50% antifreeze solution.

As we know we need to make an antifreeze solution by adding the given quantities.

Hence,

x×50%+70×25%=40%×(x+70)

x×0.5+70×0.25=0.4×(x+70)

Now, we will multiply the numbers, we get

0.5x+17.5=0.4(x+70)

Now, we will multiply both sides by 10, we get

0.5x×10+17.5×10=0.4(x+70)×10

5x+175=4(x+70)

5x+175=4x+280

Further, we will subtract 175 from both sides, we get

5x+175-175=4x+280-175

5x=4x+105

Furthermore we will subtract 4x from both sides, we get

5x-4x=4x+105-4x

x=105

Hence, 105 gallons of 50% antifreeze solution must be needed.

The solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7

How to solve the system of equations?

The system of equations is given as

2x - y + 2z = -6

-3y + z = -2

2x - 3z = -4

Subtract 2x - 3z = -4 from 2x - y + 2z = -6

This is represented as

(2x - y + 2z = -6) - (2x - 3z = -4)

This gives

- y + 5z = -2

Multiply - y + 5z = -2 by 3

-3y + 15z = -6

Subtract -3y + 15z = -6 from -3y + z = -2

This is represented as

(-3y + z = -2) - (-3y + 15z = -6)

This gives

-14z = 4

Divide by -14

z = -2/7

Substitute z = -2/7 in - y + 5z = -2

- y - 5 * 2/7 = -2

This gives

- y - 10/7 = -2

Rewrite as:

y = 2 - 10/7

Evaluate

y = 4/7

Substitute z = -2/7 in 2x - 3z = -4

2x - 3 * 4/7 = -4

This gives

2x - 12/7 = -4

So, we have:

2x = 12/7 - 4

Evaluate

2x = -16/7

Divide by 2

x = -8/7

Hence, the solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7
