he Sanchez family drove 132 miles in 3 hours before lunch. Then they drove 240 miles in 5 hours after lunch. What was their average speed for the day? A. 54.5 mi/h B. 46.5 mi/h C. 46 mi/h D. 54 mi/h

Answers

the answer is b. 46.5 

Hope this helped :)
Average speed = total distance/total time.

Total distance = 132 + 240 = 372
Total time = 3 + 5 = 8

372 / 8 = 46.5 mph
Therefore B is the correct answer.

Hello,

Answer C) x=1 for 3^1+3=3+3=6 and 2*3^1=2*3=6

Without the tables:
 2*3^x=3^x+3
==> 2*3^x-3^x=3
==>3^x * (2-1)=3
==>3^x=3^1
==>x=1

Answer:

X will equal 1

In a quadrilateral MNOP the length of side MN is (4x − 7) units and the length of side ON is (7 − 3x) units. What value of x will make it a rhombus?14
2
7
12

Answers

In a rhombus, all sides are equal.

So for the quadrilateral MNOP to be a rhombus, the given sides have to be equal. THat is

MN=ON

Adding 3x to both sides and addinf 7 to both sides

7x = 14

Now we need to get rid of 7 and for that we do division, that is

(7x)/(7) = (14)/(7)

x=2

Correct option is the second option .

Given the function y = 5x – 7, how does the y-value change as x increases by 1 A. The y-value decreases by 7. B. The y-value decreases by 2. C. The y-value increases by 12. D. The y-value increases by 5.

A company manufactures and sells novelty mugs. The manufacturing costs consists of a fixed cost of R8000 AND A VARIABLE COST OF R15.00 per mug. The mugs are sold at R35 each. Assume a linear profit function.1. Determine the profit function.
2. What is the break-even level.
3. Draw a graph depicting a profit function.

Answers

Given:
Manufacturing cost : fixed cost = 8,000 ; variable cost = 15 per mug
Selling Price: 35 per mug

Let x be the number of mugs.

Sales Revenue = 35x
Manufacturing Cost = 8,000 + 15x

Profit = Sales Revenue - Manufacturing Cost
P = 35x - 8,000 - 15x
P = 20x - 8,000

Break even level: Profit is 0
Sales Revenue = Manufacturing cost
35x = 8,000 + 15x
35x - 15x = 8000
20x = 8000
x = 8000/20
x = 400

Company must produce at least 400 mugs to break even or have 0 profit. Quantity greater than 400 will result to a profit while quantity lesser than 400 will result to a loss.
