Answer:

A) Amanda will pay $47.5

B) 0.5

C) $120

Step-by-step explanation:

A) From the graph given, at 45 miles, the total cost of rentage = $142.50

She now splits this cost with 2 of her friends. Thus each of them will pay;

Amount = 142.5/3 = $47.5

So,Amanda will pay $47.5

B) To find the slope, we will pick two points on the graph and use their respective coordinates to find the slope.

Coordinates we pick are;

(0, 120) and (50, 145)

Thus, slope; m = (y2 - y1)/(x2 - x1)

m = (145 - 120)/(50 - 0)

m = 25/50

m = 0.5

C) The equation for the graph will now be; y = mx + c

Where m is slope and c is y - intercept.

Thus;

y = 0.5x + 120

Coincidentally, c = 120 will be the fixed price of the truck while 0.5x will be the variable cost depending on how many miles are driven.

Thus renting for a day is simply the fixed cost of $120

Answer:

14, 18, 20

Step-by-step explanation:

You have to replace the number in the "s" column with the "s" in the problem. For example the first number in the table is 2 so you have to put 2 into the problem then add it with 12 and you get 14.

Answer:

  9⁸

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

Answer:

12:7

Step-by-step explanation:

The question asks for the ratio of red to blue. So first you identify how many red markers there are. In this case there are 12. Then the problem asks for blue markers. In this problem there are 7. The problem also asks for red to blue. So you put the red value first which is 12 and the blue value second which is 7. That's how you get 12:7

y = k/x

Answer:

x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)

Step-by-step explanation:

x=5±−(5)2−4(4)(9)√2(4)

x=5±−(5)2−4(4)(−9)√2(4)

x=−5±(−5)2−4(4)√−92(4)

x = -b ± √b² - 4ac / 2a

Given equation:

4x²- 5x = 9

4x² - 5x - 9 = 0

a = 4

b = -5

c = -9

x = -b ± √b² - 4ac / 2a

x = -(-5) ± √(-5)² - (4)(4)(-9) / 2(4)

x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)

The correct formula is

x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)

Step-by-step explanation:

Answer:

Whichever one equals 3y - 3

Step-by-step explanation:

I went through your answer choices and they don't really make sense. But if one of these equals 3y-3 then that's your answer.

Let the first angle be x°.

Then the second angle shall be (x - 22)°.

The two angles are complementary. Hence their sum shall be 90°.

First angle + second angle = 90°

=> x° + x° - 22° = 90°

=> 2x° = 112°

=> x° = 56°

Hence first angle = x° = 56°.

Second angle = (x - 22)° = 34°.

x+2x+7=22

x+2x=22-7

3x=15

x=15/3=5

In this equation we take the unknowns to the first member and the integers to the second member, then when subtracting and adding we divide the number of the second member by the number of the second member.

Answer:

x=15

Step-by-step explanation:

Hey There!

So what we want to do is inverse operations from the formula of area of a triangle

The area is equivalent to

[tex]A=\frac{hb}{2}[/tex]

h=height

b=base

now we setup an equation with what we are given

we are given A (area) and h(height)

so the equation looks like...

[tex]75=\frac{10b}{2}[/tex]

now we solve for b (x)

step 1 multiply each side by 2

75x2=150

/2x2 cancels out

now we have

150=10b

step 2 divide each side by 10

150/10=15

10/10 cancels out

b=15

We can conclude that the base (aka x) is equal to 15

Answer:

c

Step-by-step explanation:

b^2-4*a*c

81-20*4*1 =1

so you can factorise it to

(p+5) ( p+4 )

Answer:

First off, we can find the number that has to be increased by multiplying the original amount by 40%:

45×40%

=45×0.4

=18

We can then add the above amount to the original amount to find the toys they must sell:

45+18

=63

They must sell 63 toys to get the bonus.

Alternatively:

The total percenrage of toys need to be sold to get a bonus with the 40% increase:

=100%+40%

=140%

The amount of toys:

=45×1.4

=63

Therefore the answer is 63.

Hope it helps!
