Answers

Answer 1

Answer: You could set up a proportion for this question. 1.5 centimeters = 3.5 meters x centimeters = 180 meters 1.5 x 180 / 3.5 Rounded to the nearest whole number, the answer is 77.

51. Q(3, 9), P(-1,5)
find the coordinates of the missing endpoint if P is the midpoint of NQ

Answers

X1= 3, Y1= 9
Midpoint formula= (?,?)= (x1+x2/2 , y1+y2/2)
-2= 3+? Making ?= -5
10= 9+? Making ?= 1
So your answer is (-5,1)= N

Final answer:

The coordinates of the missing endpoint, if P is the midpoint of segment NQ, are found using the formula N = 2P - Q. Substituting the given values into this formula, the coordinates of the missing point N are (-5, 1).

Explanation:

If point P is the midpoint of segment NQ, we can use the formula for finding the coordinates of the endpoint if we know the midpoint and one endpoint. The formula states:

To find the missing endpoint (in this case, point N), we use the formula: N = 2P - Q

Substituting the given values into the formula, we get:

N = 2(-1, 5) - (3, 9)

N = (-2, 10) - (3, 9)

N = (-5, 1)

So, the coordinates of the missing endpoint N are (-5, 1).

Earyn owns French Twist Hair Salon. She charges $35 for a cut an $120 for a cut and color combo. Yesterday she had seven clients and earned $500. Let x represent only the clients that got a cut and y represent the clients that got a cut and color combo.Which of the following equations could be used to represent this situation.

y=7-x

x + y= 500

120x + 35y= 500

(35+120) (x + y)= 500

35x + 120y= 500

Answers

35x + 120x = 500
This is the correct equation because:
x represents the clients that got a cut (at a cost of 35)
So the total profit she earned from just the cuts is 35 times the number of people for a cut
y represents the clients that got a cut and color (120)
So the total profit she earned from the cut/color is 120 times the # of people for cut/color
It is equal to $500 because thats how much Earyn earned!

Two bowls of pasta at a restaurant serve 3 people. How many bowls of pasta should be ordered for 12 people?

Answers

3 people - Two bowls of pasta
12 people - ?

12 divided by 3 = 4.

4 x 2 = 8.

8 bowls of pasta should be ordered for 12 people.

12 people divided by 3 people = 4

so if 2 bowls serve 3 people...2 bowls x 4 = serve 12 people

therefore, 8 bowls serve 12 people
