Mrs. Lynch has noted that 7 out of every 10 pieces of mail she gets are junk mail. What percent of her mail is junk?

Answer:

A. Proportional by $30

B. 3 represents the hours he works

    90 represents the money he earned

C. $300

D. I don know, sorry

Step-by-step explanation:

The relationship is linear, the point (3, 90) represents in 3 hours he earns 90 dollars, in 10 hours, he earns 300 dollars, and the linear equation is y = 30x.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

This graph shows the relationship between x, the number of hours Mr. David works, and y, the number of dollars he earns.

A. Based on the graph, the relationship between x and y proportional is a linear relationship.

B. The point (3,90) represents in 3 hours he earns 90 dollars.

D. The linear equation will be

[tex]\begin{aligned} \rm y - 30 &= \rm \dfrac{90-30}{3-1} (x - 1)\\\\\rm y - 30 &= \rm 30x - 30\\\\\rm y &= \rm 30x \end{aligned}[/tex]

C. Based on the graph, the amount of money in dollars will Mr. David earn if he works 10 hours will be

y = 30x

y = 30 × 10

y = $300

Step-by-step explanation:

I think some of the question is missing.

Answer:

x = 3

x = 4.5

Step-by-step explanation:

A) 2(5x - 3) = 24

5x - 3 = 12 (divide both sides by 2)

5x = 15 (add 3 to both sides)

x = 3 (divide both sides by 5)

B) 5(2x + 1) = 50

2x + 1 = 10 (divide both sides by 5)

2x = 9 (take 1 away from both sides)

x = 4.5 (divide each side by 2)

Answer:

Answer:

18.6%

Step-by-step explanation:

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000

Percentage increase is calculated as:

Final value - Initial value/ Initial value × 100

Final value = 510000

Initial value = 430000

Percentage Increase =

510000 - 430000/430000 × 100

= 80000 / 430000 × 100

= 0.1860465116 × 100

= 18.604651163 %

Approximately = 18.6 %

Answer:

The answer would be $48.60.

Step-by-step explanation:

Some people could probably answer it better but here's my way: When you have a percentage of something you bring it to the decimal. 8% would be 0.08. We take this and multiply it by the cost: 0.08 times 15, giving us $1.2 per $15 dollars spent. 1.2 times the 3 days would be 3.6 and 15 times 3 is 45 together this would give you the grand total of $48.60.

Answer:

4. x = 5

Step-by-step explanation:

For two lines to be parallel they must have the same slope, but not be the same line. Both x=3 and x=5 both have slopes of 0, so they are parallel. Another way to tell is that x=3 is a vertical line; therefore, it will be parallel to any other vertical line, such as x=5.

Answer: $539

Step-by-step explanation:

From the question, we are informed that Mr Tyler bought 4 round-trip tickets from Florida to Canada and that the total cost is $2,156.

The cost of each ticket will then be:

= Total cost of the tickets / Number of tickets

= $2156 / 4

= $539

Therefore, each ticket cost $539

Answer:

39 degrees

Step-by-step explanation:

The sum of angle in the triangle ABC is a80 degrees

m<ACB + <BAC + <ABC =1 80

90 + <BAC + 51 = 180

141 + m<BAC = 180

m<BAC = 180-141

m<BAC = 39 degrees

Hence the measure of m<BAC is 39 degrees
