Answer:

$12.45

Step-by-step explanation:

To find the rental cost, plug in 30 as x

c(x) = 0.09x + 9.75

c(30) = 0.09(30) + 9.75

c(30) = 12.45

So, the total rental cost for 30 miles is $12.45

Answer:

15.5 miles per gallon

Step-by-step explanation:

Answer: The equation to find  Number of grand seats, s are either of the following

               x+ s= Total seats

                x+s= 19,000

                5000+s= 19,000

Number of grand seats, s= 14,000

Step-by-step explanation:

Step 1

A stadium had a total of 19,000 seats.

Given that  field seats=5,500

And the rest which are grandstand seats=?

Let field seats be represented  as x and grand seats be represented as s

such that the total  number of seats can be expressed as

x+ s = Total seats

x+ s=  19,000-------- Equation.

5000+s= 19,000

Step 2

Such that given field seats, x= 5000, Number of grand seats will  now be

x + s= 19,000

5000 + s= 19,000

s= 19,000-5000

=14,000 seats

Answer:

y+2x=8.....(1)

y-x=-1.......(2)

in equation (2) make x the subject of the formula x=y+1

substitute y+1 for x in equation (1)

y+2(y+1)=8

y+2y+2=8

3y=8-2

y=2

substitute 2 for y in equation 2

y-x=-1

2-x=-1

x=2+1

x=3

y=2 x=3

Answer: -5/4

Step-by-step explanation:

Answer:

= -5/4

Step-by-step explanation:

To find the slope, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( -9 - -4)/( -4 - -8)

   = ( -9 +4)/( -4 +8)

    = -5/4

Answer: Option B

Step-by-step explanation:

Answer:

1cm³

Step-by-step explanation:

You do not need a calculator for this.

The formula for the volume of a rectangular prism is:

Length × Width × Height = Volume

If we substitute our numbers in:

5/4 × 4/3 × 3/5 = 1cm³

All you need to do is multiply across.

5 × 4 × 3 = 60

4 × 3 × 5 = 60

The numerator and denominator both equal 60. So the fraction would look like this if you were to keep it as a fraction.

60/60

Answer:

$10

Step-by-step explanation:

Let's take this step by step. First, we know that Cindy has -$40 in her bank account. She then adds the $100 she earned, so we add -40 and 100:

-40 + 100 is the same as 100 - 40, which is 60. So, Cindy now has $60 in her bank account. Next, she took out $50. We must subtract that from what she has from her bank account:

60 - 50 = 10

Therefore, Cindy has $10 in her bank account now.

Answer:

V>-8

Step-by-step explanation:

The given inequality is :

4-V>12

Subtracting 4 from both sides.

4-V-4 > 12-4

-V>8

or

V>-8

So, the value of V is more than -8.

Answer:

Increasing

Step-by-step explanation:

Let us take a look, at these fractions in decimal forms.

1/7 = 0.14

2/7 = 0.28

3/7 = 0.42

4/7 = 0.57

5/7 = 0.71

From, these we can see that the value of the numbers keep increasing. So, the sequence above is increasing.

Answer: The rate represents a decrease in speed for each 1% grade increases.

Step-by-step explanation:

You can use the fact that normal slope is measurement of how much the height changes as we walk on the ground for a unit distance forward. And that percent calculates everything compared to 100 parts.

The rate of change or slope, in this situation tells that if we walk 100 units horizontally, then the slope percent gives us the amount of height increased compared to height before walking 100 units.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Suppose that we have to measure the rate of change of y as x changes, then we have:

[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

where we have

[tex]\rm when \: x=x_1, y = y_1\\when\: x = x_2, y= y_2[/tex]

Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.

(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)

(where dependent variable is height and the independent variable is the distance walked horizontally)

Slope percent  = [tex]Slope \times 100[/tex] = [tex]\dfrac{y_2 - y_1}{x_2 - x_1} \times 100[/tex]

This, shows that, if we walk 100 units horizontally, then the slope percent gives us the amount of height increased.

Answer: 48 feet below the surface

Step-by-step explanation:

From the question, we are informed that two divers are underwater. Nick is 33 feet below the surface while Tristan is 15 feet above him.

Tristan's depth will be represented as x.

Therefore, x - 33 = 15

x = 15 + 33

x = 48

Therefore, the answer is 48 feet below the surface.

Answer:

B 18 feet below

Step-by-step explanation:

So subtract 33-15 bechas depth means below and since tristan has less of a depth to go rather than Nick you would subtrac.
