Mr. Hudson is a car salesman. He makes a fixed amount of $1,000 a month and receives $250 for every car that he sells. Which inequality shows the number of cars, n, Mr. Hudson must sell in a month to earn a minimum of $6,000?

Answers

Answer:

250n + 1,000 ≥ 6,000

Step-by-step explanation:

You know that he makes 250 dollars per car her sells and he automatically makes 1000 per month. n is representing the number of cars he sold and that is multiplied by the worth of each car. If he needs a MINIMUM of 6000 dollars. he must make 6000 dollars or more which can also be shown as ≥. Hope this helped!

Carolina goes to a paintball field that charges an entrance fee of \$18$18dollar sign, 18 and \$0.08$0.08dollar sign, 0, point, 08 per ball. The field has a promotion that says, "Get \$10$10dollar sign, 10 off if you spend \$75$75dollar sign, 75 or more!" Carolina wonders how many paintballs she needs to buy along with the entrance fee to get the promotion.

Answers

Answer:

713 paint balls

Step-by-step explanation:

The inequality equation for the above question is given as:

$18 + $0.08 × b ≥ 75

Where b = number of paint balls

$18 + 0.08b ≥ 75

0.08b ≥ 75 - 18

0.08b≥ 57

b ≥ 58/0.08

b ≥ 712.5

b≥ 713 paint balls

Hence, Carolina would need to buy 713 paintballs along with the entrance fee to get the promotion.

Answer:

undefined slope

Step-by-step explanation:

This is a vertical line parallel to the y- axis.

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, - 3) and (x₂, y₂ ) = (- 5, - 6) ← 2 points on the line

m = [tex]\frac{-6+3}{-5+5}[/tex] = [tex]\frac{3}{0}[/tex]

Since division by zero is undefined then the slope is undefined.

Note that all vertical lines have an undefined slope

A pile of pebbles has a weight of 95 kg.
Some of the pebbles put into a small bag.
The rest of the pebbles is put into a large bag.
The pebbles in the large bag weighs 45 kg more than the pebbles in the small
What is the weight of the pebbles in the large bag?​

Answers

Answer:

70kg

Step-by-step explanation:

s = small bag

b = big bag

Equations

s + b = 95

s + 45 = b

plug in

s + s + 45 = 95

2s + 45 = 95

2s = 50

s = 25

plug in to find big bag

25 + 45 = b

70 = b

Answer:

The weight of the pebbles in the large bag is 70kg.

Step-by-step explanation:

This looks like a substitution algebra problem. To do this, I’m going to mark the large bag with (L) and the small bag with the variable, (s). I will make first 2 equations to show the value. The first equation would be L=45+s. The second equation would be 95=L+s. Since L is literally 45+s, add this into the 2nd equation. This would be 95=45+s+s. You should have 95= 45+2s and you would subtract 45 from both sides then. Finally, divide 2s by 2 to get what the small bag weighs, (which is 25kg). To find the large bag’s weight, use the first equation to find the answer. L= 45+s or 25. The answer would bring us to 70 kg.

Answers

Answer:

Blue is linear

Step-by-step explanation:

For lines to be linear on a graph, they have to follow these 2 rules:

-be a straight line

-be written in the form of y=mx+b

Therefore, blue is linear and orange is nonlinear

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. y=-16x^2+242x+73

Answers

Answer:

t = 15.42 s

Step-by-step explanation:

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation.

[tex]y=-16x^2+242x+73[/tex]

We ned to find the time when the rocket will the ground. For this, y = 0

[tex]-16x^2+242x+73=0[/tex]

It is a quadratic equation whose solution is given by :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

Here, a = -16, b = 242 and c = 73

[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, x=\dfrac{-b-\sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-242+ \sqrt{(242)^2-4(-16)(73)} }{2(-16)}, x=\dfrac{-242- \sqrt{(242)^2-4(-16)(73)} }{2(-16)}\\\\=-0.295\ s, 15.42\ s[/tex]

Neglecting negative value.

So, it will hit the ground in 15.42 s.

t = 15.42 s
