Answer:

66.32

Step-by-step explanation:

Hello!

[tex]\large\boxed{66.32 m}[/tex]

We are given the area, so we can solve for the width given the length:

A = l × w

Thus:

272.4 = 15 × w

w = 18.16 m

The perimeter of a rectangle can be calculated using this equation:

P = 2l + 2w

Therefore:

P = 2(15) + 2(18.16)

P = 30 + 36.32 = 66.32m

Answer:

A is the Far Left

B is the Base

C is the Hypotenuse

Step-by-step explanation:

Interpretation

Answer:

Angle BAC corresponds with side length BC

Side length AC will correspond with angle ABC

Step-by-step explanation:

In a triangle, the side length will correspond to the angle opposite it and vice versa.

That is, the side length opposite angle A corresponds to the side of Angle A

Hence, in the triangle given above ;

Angle BAC corresponds with side length BC, because BC is opposite BAC

Side length AC will correspond with angle ABC, because AC is directly opposite angle ABC.

Answer:

a) 1/2

b) 9/40

Step-by-step explanation:

Given

Total number of families living in Willbrook Farms Development = 20

Number of families preparing their own federal income taxes for last year = 10

Number of families for which taxes were prepared by a local professional = 7

Number of families for which taxes were prepared by H&R Block = 3

a) Probability of selecting a family that prepared their own taxes = 10/20 = 1/2

b) The probability of selecting two families, both of which prepared their own taxes

10/20 * 9/20 = 9/40

Answer:

[tex]2[/tex]

Step-by-step explanation:

Given:

[tex]-2(1-4x)=3x+8[/tex]

Let's distribute the parenthesis

[tex]-2+8x=3x+8[/tex]

Let's subtract [tex]-3x[/tex] from both sides

[tex]-2+5x=8[/tex]

Let's add [tex]2[/tex] to both sides

[tex]5x=10[/tex]

Now, let's divide both sides by [tex]5[/tex] to get [tex]x[/tex] alone

[tex]x=2[/tex]

Hope this is helpful

Step-by-step explanation:

How to solve your problem

−2(1−4)=3+8

-2(1-4x)=3x+8−2(1−4x)=3x+8

Solve

1)

Rearrange terms

−2(1−4)=3+8

-2({\color{#c92786}{1-4x}})=3x+8−2(1−4x)=3x+8

−2(−4+1)=3+8

-2({\color{#c92786}{-4x+1}})=3x+8−2(−4x+1)=3x+8

2)

Distribute

−2(−4+1)=3+8

{\color{#c92786}{-2(-4x+1)}}=3x+8−2(−4x+1)=3x+8

8−2=3+8

{\color{#c92786}{8x-2}}=3x+88x−2=3x+8

3)

Add 

2

22

 to both sides of the equation

8−2=3+8

8x-2=3x+88x−2=3x+8

8−2+2=3+8+2

8x-2+{\color{#c92786}{2}}=3x+8+{\color{#c92786}{2}}8x−2+2=3x+8+2

4)

Simplify

Add the numbers

Add the numbers

8=3+10

8x=3x+108x=3x+10

5)

Subtract 

3

3x3x

 from both sides of the equation

8=3+10

8x=3x+108x=3x+10

8−3=3+10−3

8x{\color{#c92786}{-3x}}=3x+10{\color{#c92786}{-3x}}8x−3x=3x+10−3x

6)

Simplify

Combine like terms

Combine like terms

5=10

5x=105x=10

7)

Divide both sides of the equation by the same term

5=10

5x=105x=10

55=105

\frac{5x}{{\color{#c92786}{5}}}=\frac{10}{{\color{#c92786}{5}}}55x=510

8)

Simplify

Cancel terms that are in both the numerator and denominator

Answer:

2 feet

Step-by-step explanation:

Use the cube volume formula, V = s³, where s is the side length.

Plug in 8 as V, and solve for s:

V = s³

8 = s³

Take the cubed root of each side:

2 = s

So, the length of each side is 2 feet.

Answer:

[tex]2 feet[/tex]

The Solution is:

Use the cube volume formula, V = s³, where s is the side length.

Plug in 8 as V, and solve for s:

V = s³

8 = s³

Take the cubed root of each side:

2 = s

So, the length of each side is 2 feet.

Answer:

(60.382 ; 83.998)

Step-by-step explanation:

The confidence interval is given as :

Mean ± Margin of error

Mean = 72.19

The margin of error is : Tcritical * s/√n

n = 13 ; s = 15.88

Tcritical at 98%, df = 13-1 = 12 = 2.681

Margin of Error = 2.681 * 15.88/√13 = 11.808

Confidence interval = 72.19 ± 11.808

(60.382 ; 83.998)

Answer:

2 hours and 30 minutes

Step-by-step explanation:

25/5 = 5 Divide to find out how many fives are there in 25.

5 x 30 = 150 minutes (multiply 5 by 30 to find out how many minutes)

150/60 = 2.5 hours or in other words, 2 hours and 30 minutes ( Convert the minutes into hours by dividing by 60)

Answer:

112 cm²

Step-by-step explanation:

The area of a triangle is given by :

Area = 1/2 * base * height

Base = 14 cm ; height = 16 cm

Area = 1/2 * 14 * 16

Area = 7 * 16

Area = 112 cm²

Answer:

Proportional

Step-by-step explanation:

Proportional functions can be written as [tex]y=kx[/tex], where [tex]k[/tex] is some constant of proportionality. Plugging in (x,y) pair into this function will yield a constant of proportionally of [tex]k=\frac{3}{2}[/tex] and since this constant is maintained through all the coordinate pairs in the table, the table is proportional.

Answer:

There are 154,440 ways.

Step-by-step explanation:

The word arrange means that the order in which the books are placed is important, which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this question:

5 books from a set of 13. So

[tex]P_{(13,5)} = \frac{13!}{(13-5)!} = 154440[/tex]

There are 154,440 ways.

Answer:

C) It is often difficult to solve complicated problems with tables alone.

Step-by-step explanation:

Tables can be regarded mathematical tools used in representation of data in very organised form. The arrangements is in form of rows and columns which often gives description of an array of data in table format. Tables are best use in solving simple problems. Tables helps to show results for calculation that has varying arguments. It should be noted that the disadvantage to using tables is that It is often difficult to solve complicated problems with tables alone.

Answer:

Gary spends a total of $166.05

Step-by-step explanation:

15% tip: would be 15% of 135, so 0.15 times 135, which would be $20.25 for the tip before tax

8% tax: would be 8% of 135, so 0.08 times 135, which would be $10.8

Then we add $20.25+$10.8+$135= $166.05
