If a=7 and b=2 what is 2a+3b ?

Given:

Length of the building  = 120 feet

Width of the building = 40 feet

Length of the model = 6 feet

To find:

Width of the model.

Solution:

The scale model similar to the original figure and the corresponding sides of the similar figures are proportional.

Let x be the width of the building.

[tex]\dfrac{\text{Length of the building}}{\text{Length of the model}}=\dfrac{\text{Width of the building}}{\text{Width of the model}}[/tex]

[tex]\dfrac{120}{6}=\dfrac{40}{x}[/tex]

[tex]20=\dfrac{40}{x}[/tex]

[tex]x=\dfrac{40}{20}[/tex]

[tex]x=2[/tex]

Therefore, the width of the model is 2 feet.

Answer:

27 and 597

Step-by-step explanation:

To evaluate A5 and A100, substitute n = 5, n = 100 into An , that is

A5 = 6(5) - 3 = 30 - 3 = 27

A100 = 6(100) - 3 = 600 - 3 = 597

Answer:

5n=6n-3

C.L.T

6n-5n=3

n=3

ii.100n=6n-3

C.L.T

100n-6n= -3

94n/94=-3/94

n=-0.032

Step-by-step explanation:

Answer:

Events A and B are dependent

Step-by-step explanation:

If A and B are two events such as A and B are dependent then

P(A∩B)  P(A) P(B)

An event A will occur with probability 0.4 that is  

An event B will occur with probability 0.6 that is  

The probability that both A and B will occur is 0.20 that is P(A∩B) = 0.20

Therefore,

P(A∩B)  P(A) P(B)

So,

events A and B are dependent

Answer:

  $35 per hour

Step-by-step explanation:

The total charge is the sum of costs of parts and labor. If h is the cost of a labor hour, then we have ...

  188.75 = 75 + 3.25h

  113.75 = 3.25h . . . . . . . . subtract 75

  113.75/3.25 = h = 35 . . . divide by the coefficient of h

The cost of labor, per hour, is $35.

Answer:

no

Step-by-step explanation: yes

Answer:

Median: 17

Q1: 10

Q3: 23

Step-by-step explanation:

2, 4, 9, 11, 12, 16,   18, 20, 22, 24, 28, 32

Median is middle number/average of the 2 middle numbers. 16 + 18 = 34/2 = 17

First/lower quartile/Q1 = middle of lower half of ordered data set

= 9 + 11 = 20/2 = 10

Third/upper quartile/Q3 = middle of upper half of ordered data set

= 22 + 24 = 46/2 = 23

Answer:

there are multiple solutions to this but one is...

3+3+3+3+2+2+2+3+2+2+3

Step-by-step explanation:

you can create other solutions by taking both 2 and 3 consecitvly and adding them until you get 28.

Answer:

She made eight 2 pointers

She made four  3 pointers

Step-by-step explanation:

2x + 3y = 28

x + y    = 12                 Multiply this equation by 2

2x + 2y =24

Write the first and third equations underneath each other,

2x + 3y = 28

2x + 2y = 24              Subtract.

        y = 4

x + y = 12

x + 4 = 12                     Subtract  4 from each side

   - 4    -4

x = 8

Answer: 140cm²

Step-by-step explanation:

Perimeter of a rectangle is calculated as: = 2(length + width)

where,

Length = x+4

Width = x

Therefore, perimeter = 2(length + width)

2(x + x+4) = 48

2(2x + 4) = 48

4x + 8 = 48

4x = 48 - 8.

4x = 40

x = 40/4

x = 10cm

The other side = x+4 = 10+4 = 14cm

Area = length × width

Area = 10cm × 14cm

Area = 140cm²

Given:

Consider the population of California = [tex]3.9\times 10^7[/tex]

Consider the population of Maine = [tex]1.3\times 10^6[/tex]

To find:

The difference between the population of California and Maine.

Solution:

We have,

Population of California = [tex]3.9\times 10^7[/tex]

Population of Maine = [tex]1.3\times 10^6[/tex]

Difference between the population of California and Maine is

[tex]\text{Difference}=3.9\times 10^7-1.3\times 10^6[/tex]

[tex]\text{Difference}=3.9\times 10^7-(0.13\times 10)\times 10^6[/tex]

[tex]\text{Difference}=3.9\times 10^7-0.13\times 10^7[/tex]

[tex]\text{Difference}=(3.9-0.13)\times 10^7[/tex]

[tex]\text{Difference}=3.77\times 10^7[/tex]

Therefore, the correct option is D.

Answer:  the third one

Step-by-step explanation:

Answer:

x + y = 35  equation 1

x + 2y = 62  equation 2

He made 8 1 point free throw

He made 27 2 point field goal

Step-by-step explanation:

let x = 1 point free throw

y = 2 point field goal

two equations can be derived from the question

x + y = 35  equation 1

x + 2y = 62  equation 2

Subtract equation 1 from 2

y = 27

Substitute for x in equation 1

x = 35 - 27 = 8

He made 8 1 point free throw

He made 27 2 point field goal
