Answers

8.75

you need to divide 26.25 by 3 which is equal to 8.75

I need to find the area, what is it?

Answers

Answer:

.75

Step-by-step explanation:

You have to do B * H / 2   which 1.5 x 1 = 1.5, and then 1.5/2 = .75

In order to find the area of a triangle, you must do 1/2 base x height.

So to plug in the numbers, you will have 1/2 x 1 x 1.5.

1/2 x 1 = 0.5 and 0.5 x 1.5 = 0.75

A salesperson’s commission rate is 4%. What is the commission from the sale of $39,000 worth of furnaces? Suppose sales would double. What would be true about the commission?

Answers

Answer:

The earnings will double

Step-by-step explanation:

Step one:

given data

we are told that the sales person's earnings is 4% of the sales made.

given that the sales made is $37,000 worth of furnaces.

Step two:

we want to find 4% of $37,000

=4/100*37000

=0.04*37000

=1480

hence for $37,000 the earning will be $1480.

Now suppose sales is doubled that is 37000*2= 74000

we want to find 4% of $74,000

=4/100*74000

=0.04*74000

=2960.

the earnings is $2960.

So if sales doubles the earnings will double

A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results:

80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
4) Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium. Show your work.

Answer:

210 student's

Step-by-step explanation:

80 students chose the aquarium.

60 students chose the science center.

30 students chose the planetarium.

40 students chose the farm.

The students can't vote for more than one place, so you just add all the numbers together.

80 + 60 + 30 + 40 = 210 students

80 choose the aquarium

20 points each!!! Heather has 2 less than 5 times the amount of shoes that Donna has, Gina has 1 more than 2 times
amount of shoes that Donna has. Let x represents how many shoe Donna has.

a. Write an expression that represents how many more pairs of shoes Heather has than Gina.

b. Simplify the expression:

c. How many more pairs of shoes does Heather have is Donna has 14 pairs of shoes?

Answers

Answer:

A. (5x - 2) - (2x +1)

B.  x -1

C. 68

Step-by-step explanation:

Heather = 5 times Donna -2   H = 5D - 2

Gina = 2 times  Donna + 1    G = 2D + 1

Plug in D for X and you get

H = 5x -2

G = 2x + 1

If Heather's expression is 5x -2 and Gina's expression is 2x + 1 then to show how many more Heather has than Gina. You have to subtract Gina from Heather.

(5x - 2) - (2x +1)

Now to simplify it, you just combine all the like terms.

5x - 2 - 2x -1 = 3x - 3   and then you can simply this further by dividing all terms by 3.    x - 1

To solve how many Heather has if Donna has 14. You substitute 14 for x in Heather's equation.    5 (14) -2  =  70 - 2 = 68
