Vicki earns $30 for washing 6 cars. If Vicky charges the same rate, how many cars. must she wash to earn $35? (Label your answer for full credit)

Answers

Answer:

7

Step-by-step explanation:

if she got 30 from 6 cars then 30/6 is 5. $5 per car times 7 is $35

6*5=30 so she charges 5 dollars a car. so to earn 35 dollars she would have to wash an extra car here is the equation 30/6=5 anyway she needs to wash 7 cars because 7*5=35

Mary had 4 friends over to study for a test. Before her friends arrived, she baked 4 pies to share equally among herself and her friends. How much pie is each person going to get. (Please also explain it )

Answers

Answer:

Each person gets 1 pie

Step-by-step explanation:

Becasue if there are 4 pies and 4 people than since the amount of pies and people are equal it cancels out, meaning there are no pies left to be eaten and no people left that dont  have a pie to eat    

If the pie has 6 slices for each pie, they would all get 6 slices or 1 pie.

4x6=24

In this diagram, each square represents 1 km. What is the displacement of the car?​

Answers

Answer: C) 2 km west

Explanation:

With displacement, all we care about is the beginning and end. We don't care about the middle part(s) of the journey. So we'll take the straight line route from beginning to end when it comes to computing displacement.

We start at A(0,0) and end at B(-2,0). Going from A directly to B has us go 2 km west. Keep in mind that displacement is a vector, so you must include the direction along with the distance.

Find the value of W please help due tomorrow

Answers

Answer:

59 degrees

Step-by-step explanation:

All the angles of a triangle (when combined) result in 180 degrees. This means that:

Angle 1 + angle 2 + angle 3 = 180 degrees.

We can see here that the shape here is a right triangle (noted by the square in the corner). This means that the angle set with the square is equal to 90. With this, we already have two of our angles! All we need is to set the equation using w, the angle you'll want to find:

31 + 90 + w = 180

w = 59

And there you are! Make sure to practice a few more problems like these to really get the hang of it. Good luck!
