Ignore the paragraph part just part a and part b, please & thank you!

======================================================

Work Shown:

c = number of correct answers

w = number of wrong answers

n = number of questions not attempted

2c = points you get from all the correct answers

-1w = points you get from all the wrong answers

0n = points you get from all the questions attempted

2c-1w+0n = 2c-w = total number of points

In this case, she got 8 correct answers and 2 wrong answers. So c = 8 and w = 2 which leads to

2c-w = 2*8-2 = 16-2 = 14

Her total score is 14.

Answer:

500$ is the answer....

Answer:

$60 and $560

Step-by-step explanation:

Prt= Interest

(500)(0.04)(3)= $60

A = P(1 + rt)

A = 500 (1 + 0.04(3))

A= $560

Answer:

Jack is wrong because 3,000 milliliters is equal to 3 liters.  If the tub already has 5 liters in it, adding 3 liters makes the tub have 8,000 liters. Angelina is correct when she says Jack is wrong.

Answer:

$1850

Step-by-step explanation:

The annual cost of Martinez's family membership for medical insurance is $3,900.

The company pays 50% of the cost.

So, the cost paid by the company= 50% of $3,900.

[tex]=\frac {50}{100}\times 3900=\$1850[/tex]

The remaining cost for the family medical insurance must be paid by Gail Martinez.

So, the annual payment by her =$3900-$1850=$1850

Hence, she pays $1850  annually for medical insurance.

Answer:

The land that is covered with an irrigation arm of 370 ft is  [tex]430,084\ ft^2[/tex]

Step-by-step explanation:

Area of the circle

Being r the radius of a circle, its area can be calculated as follows:

[tex]A=\pi\cdot r^2[/tex]

The irrigation arm acts as the radius of the irrigation circle, thus r=370 ft. The land covered is the area under the irrigation arm, thus:

[tex]A=\pi\cdot 370^2[/tex]

[tex]A=430,084\ ft^2[/tex]

The land that is covered with an irrigation arm of 370 ft is  [tex]430,084\ ft^2[/tex]

Answer: (2, 2 )

Step-by-step explanation:

Plug the x and y-values into the given equation.  If it makes a true statement, then it is a solution.

y = x +  

(0,0) → 0 = 0 +     FALSE

(1, ) →   = 1 +     FALSE

(2, 2 )  →  2  = 2 +     TRUE

Answer:

800 blue marbles

Step-by-step explanation:

Since the ratio of red to blue is 3 to 4, we know that there is 600 red marbles.

Using this information we know that 3 and 600 are both red marbles, now we multiply 3 by 200 to get a total of 600 red marbles. You can also find the value needed to multiply the 3 by dividing 600 by 3.

Since we know that 1 ratio is 200, we multiply 4 by 200 to get 800 blue marbles.

Answer:

Flip the triangle around at the point Z

Step-by-step explanation:

The reason you need to flip the triangle at point Z is because, when reflecting, you need to reflect it over the line given. since the reflective line is x = 1, you reflect it off the line x of 1 or point (1,0). Also, when reflecting, the line of reflection will actually be perpendicular with the point given because, when reflecting, x = 1 means that all of the x coordinates on the line will equal 1. For example, your line would have to pass through the points (1,-4), (1,-2), (1,0), (1,2), so on so forth so in this statement, all of your points will be reflected over that line and since z is on that line, the triangle is just fliped at point z.

Answer:

Maggie is 13

Step-by-step explanation:

Honestly, I just kept trying ages starting from 10 because I knew it wasn't going to be less than that. Then I did whatever age, in this case 13, and multiply it by  4. Then minus 11 from that number. Then take that end number and add it to the beginning number(maggies age) and you should get 54.

Math Equation Explanation:

13*4 = 52                           (Maggies Age) x 4

52-11= 41                            The question stated that Maggie's brother was 11                                             -------------------------------------years younger than her age times 4.

41 + 13 =54                          The sum of both their ages.

Step-by-step explanation:

Answer: y=(-5x/2)+5

Step-by-step explanation:

There is no clear cut explanation for this. y cannot directly equal a number. Let me show you.

Subtract 5x from both sides.

5x-5x+2y=10-5x

2y=-5x+10

Then to get to y to being by itself, divide by 2 on both sides

(2y/2)=(-5x+10)/2

y=(-5x+10)/2----> or -5x/2 + 10/2

y=(-5x/2)+5

Answer:

The answer is below

Step-by-step explanation:

Meghan covered 5 miles with 9,780 steps. The number of steps per mile = 9780 / 5 = 1956 steps per mile

David covered 6 miles with 9,780 steps. The number of steps per mile = 11928 / 6 = 1988 steps per mile

This means that David covered more steps per mile compare to Meghan. The number of more steps = 1988 - 1956 = 32

Therefore David had 32 more steps per mile
