a travel guide has dimensions 8 in. by 10 in.
what scale factor should be used to make an enlarged version that has dimensions 12 in. by 15 in. ?

A. 0.67
B. 1.5
C. 3
D. 4

Answer:

2/5.

Step-by-step explanation:

1 3/5 / 4

= 8/5 / 4

= 8/5 * 1/4

= 8/20

= 2/5.

Step-by-step explanation:

[tex] \sf \longmapsto \boxed{ \sf \: y = - 8}[/tex]

Answer:

Point-slope equation: y - 10 = 2(x - 3)

Step-by-step explanation:

Given the slope of the line, m = 2, and the point, (3, 10):

Let the slope (m) = 2

                 (x₁, y₁) = (3, 10)

Substitute these values into the point-slope form, y - y₁ = m(x - x₁):

y - y₁ = m(x - x₁)

y - 10 = 2(x - 3)  ⇒ This is the point-slope form.

Answer:

x = 1

Step-by-step explanation:

Here is what you need to know:

f(x) represents the y-value.

The x in the parenthesis represents the x-value.

Another way to write f(x) = 1 is y = 1.

So now you are just finding the x-value for when y = 1. Looking at the graph, when y is 1 ( 1 on the y-axis), x has to be 1! This is because when you go up one, the only value that matches that point is 1!

Hope this helps :)

Answer:

20 hours

Step-by-step explanation:

20 hours, since you have to find the remaining 80% of her dance time.

I thought of this as follows:

1/5 = 4

2/5 = 8

3/5 = 12

4/5 = 16

5/5 (100% of her dance time!) = 20 hours!

I hope this helped a bunch! Tell me if you need any further assistance...

Answer:

Given points= (0,2) (1,0)

I think its 0.83 or 8% hope this helps!

Step-by-step explanation:

Answer:

83

Step-by-step explanation:

Step-by-step explanation:

-25 = -5/3u

-25.3u = -5

-75u = -5

u = -5/-75

u = 1/15

So we know that the number x is multiplied by 4, and then is bigger then itself by 45, so so lets set up this equation.

4x = x + 45

The 4x is our x multiplied by 4 and the x + 45 is when it exceeds itself by 45.

Now lets solve:

4x = x + 45

Bring x to one side to isolate the variable:

4x - x = 45

3x = 45

Now we divide the 3 from the 3x in order to fully isolate the variable:

x = 45 / 3

x = 15

Lets plug 15 in to double check the answer:

4(15) = 15 + 45

60 = 60

Yes!

This means that 15 is the number multiplied by 4 and exceeded by 45.

I hope this helps! :)

Answer:

It costs $51

Expression:

16x = 68

12x = ?

Step-by-step explanation:

Lets first find out how much one sq. ft. of flooring costs:

16x = $68

x = $68/16 = $4.25

Next, lets multiply the unit rate by 12 to find the answer:

12x = Answer

12 * (4.25) = $51

Answer:

51

Step-by-step explanation:

68÷16 = 4.25

12 × 4.25 = 51

Answer:

a) y=200x+450

b) y=200(8)+450 = $2050

c) 21 months

Step-by-step explanation:

a) y=200x+450

200 per month plus her initial deposit of 450

b) y=200(8)+450 = 2050

To see how much she'll have after 8 months, plug in 8 for x

c) 4500<200x+450

4050<200x

20.25<x

x>20.25, so after 21 months since 20.25 is more than 20 months you have to round up to 21

Answer:

36%

Step-by-step explanation:

47/132=36%

The = is means the equal sign with the ~ position

The percent of the students prefer superhero movies rounded to the nearest percent is; 36%

The table of this random survey of students when seen online tells us that;

Total number of students that prefer super hero movies = 47

Total Number of Students that prefer Comedy = 50

Total Number of Students that prefer drama = 35

Thus;

Total number of students surveyed = 47 + 50 + 35

Total number surveyed = 132

Thus;

Percent of the students that prefer superhero movies = 47/132 * 100%

Percent of the students that prefer superhero movies = 36%

Answer:

Part a: Bill’s car travels 30 miles per gallon of gas. If y represents the number of miles the car travels on x gallons of gas, the equation that represents this situation is y = 30x.

Part b:       gallons of gas (x) miles (y)

                                     1          30

                                     2  60

                                     3  90

Part c: There is no x-value that would lead to multiple y-values.

Part d: Yes, y = 30x is a function, because for every input, or x-value, there is only one output, or y-value.

h^2 = 7.5^2 - 6.2^2

h^2 = 17.81

Height h= 4.22.
