Andru [333]

Answer:

1. B

2. B

Step-by-step explanation:

1. Three points are collinear if they lie on the same line. The diagram shows two triples of points that lie on the same line:

points B, C and D;
points A, C and E.

Thus, option B is true.

2. Another way to name the plane is to select three points which do not lie on the same line and write them consequently. As you can see from the diagram, points B, F and D lie on the plane M, but do not lie on the same line. Thus, another way to name plane M is BFD.

At a car dealership, salespeople earn a 5% commission on the first $10,000 of every sale, plus a 3% commission on any amount ove

o-na [289]

Answer:

The total comission on the sale was $375.

Step-by-step explanation:

Since the salesperson sold the car for $12,300, the total comission on the sale would be equal to the 5% of $10,000 plus the 3% of the remaining amount which would be:

Total comission=(10,000*5%)+(12,500-10000)*(3%)

Total comission=500+(2,500*3%)

Total comission=300+75

Total comission=375

According to this, the answer is that the total comission on the sale was $375.

Maria and Katy each have a piece of string. When they put the two pieces of string together end to end, the total length is 84in

kramer

Maria's piece is 45 inches long

Katy's piece is 39 inches long

Step-by-step explanation:

Maria and Katy each have a piece of string

When they put the two pieces of string together end to end, the total length is 84 inches
Maria’s string is 6 inches longer than Katy’s

We need to find how long is Maria’s piece of string and how long is Katy’s piece of string

Assume that the length of Maria's piece is x inches and the length of Katy's piece is y inches

∵ Maria's piece is x inches

∵ Katy's piece is y inches

∵ The total length of the two pieces is 84 inches

- Add x and y, then equate the sum by 84

∴ x + y = 84 ⇒ (1)

∵ Maria’s string is 6 inches longer than Katy’s

- That means equate x by the sum of y and 6

∴ x = y + 6 ⇒ (2)

Now we have a system of equations to solve it

Substitute x in equation (1) by equation (2)

∴ (y + 6) + y = 84

- Add the like terms in the left hand side

∴ 2y + 6 = 84

- Subtract 6 from both sides

∴ 2y = 78

- Divide both sides by 2

∴ y = 39

- Substitute the value of y in equation (2) to find x

∵ x = 39 + 6

∴ x = 45

Maria's piece is 45 inches long

Katy's piece is 39 inches long
