Answer:

(-6,-5)

Step-by-step explanation:

X+y=-11

solve for x

x=-11-y

substiute x value into 2nd equation

2x-3y=3

2(-11-y)-3y=3

-22-2y-3y=3

-5y=25

y=-5

substitute -5 for y in either equation to find x

x+y=-11

x+-5=-11

x=-6

Answer: 103832

Step-by-step explanation:

Answer:

The correct answer is C

Step-by-step explanation:

Helpful fact- All triangles are 180 degrees

Angle 1 = 31 degrees

Angle 2= 71 degrees

X= Angle 3

Y = Angle 1&2 Sum

So by adding Angles 1 & 2 we get a sum  to subtract from 180 and get a difference. That difference will be Angle 3.

Angle 1 + Angle 2 = Y

180 - Y= X

31 + 71 = 102 degrees   Y= 102 degrees

180 - 102 = 78 degrees  X= 78 degrees

Answer:

22

13

4

-5

Step-by-step explanation:

This should be it

Answer:

1. When x=-6, y=22.

2. When x=-3, y=13.

3. When x=0, y=4.

4. When x=3, y=-5

Step-by-step explanation:

To solve the table, you have to plug in the x values on the left individually into the function of y=-3x+4.

Plugging in the first x value in the table (-6) will result in the equation y=-3(-6)+4. To solve, you first multiply the -3 with the (-6), which will will equal 18. So, the equation will now look like this: y=18+4. Then, solving the equation (18+4) you get 22. Which means, when x=-6, y=22.

Do this same process with the other three x values plugged into the function as x, and this is what you should get:

2. y=-3(-3)+4    

   y=9+4

   y=13

When x=-3, y=13.

3. y=-3(0)+4

   y=0+4

   y=4

When x=0, y=4.

4. y=-3(3)+4

   y=-9+4

   y=-5

When x=3, y=-5

Answer:

Break-even point in units= 40

Step-by-step explanation:

Giving the following information:

Unitary variable cost= $20

Selling price per unit= $30

Fxed costs= $400

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 400 / (30 - 20)

Break-even point in units= 40

Answer:

The median is 55.833

The range is 90

The mode is 4

Step-by-step explanation:

To find median you

1. Arrange your numbers in numerical order.

2. Count how many numbers you have.

3. If you have an odd number, divide by 2 and round up to get the position of the median number.

4.If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

To find mode you put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode.  To find range you first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.

Answer: 180 pushups

Step-by-step explanation: First set up a proportion. The proportion would be 30 pushups over 60 seconds  equal x over 360 seconds. Then you would cross multiply which is 60 times x which is 60x .After that do 30 times 360 which is 10,800.Now you have 60x = 10,800.NOw divide both sides by 60 which gives you 180 as x.

Answer:

(a) 2 degree celsius per hour

(b) 3 degree celsius per hour.

Step-by-step explanation:

From the question,

(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).

T' = T/t.................... Euqation 1

Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.

Substitute into equation 1

T' = 4/2

T' = 2 degree celsius per hour.

(b) Also,

Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)

T' = T/t

Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours

T' = 6/2

T' = 3 degree celsius per hour

16,507.38

Step-by-step explanation:

The equation for this would be 8600(1 + 0725/52)^52*9

9 is the years, 52 is the compounded weekly, and 8600 is the initial amount.

Solving the equation, we get:

Answer:  127.795 in^2

Step-by-step explanation:

The area of any triangle is [tex]\frac{1}{2} \cdot \text{base} \cdot \text{height}[/tex][tex]\frac{1}{2} \cdot \text{base} \cdot \text{height}[/tex]

The surface of this pyramid is composed of three slanted triangles and the base.

Area of slanted sides (3 of them):

The base of each is 6.1 -- the sides of the bottom triangle all have the same length.  The height of a slanted side is 12.2 .

Area of one slanted side is .5(6.1)(12.2) = 37.21

There are 3 identical sides, so the area of all 3 is 3 x 37.21 = 111.63 .

Area of the pyramid's base:

The base of that triangle is 6.1, and its height is 5.3, so its area is

.5(6.1)(5.3) = 16.165

The total area of all four faces is 111.63 + 16.165 = 127.795

answer is B

Answer:

4(120)(.225) + x (120)(.225) = $351

9 units sold on Tuesday

Step-by-step explanation:

1. You can easily figure how much money was made on Monday by multiply the total units sold by the price per unit by the commission in decimal form.  Here you get $108.

2.  Subtract that $108 from the $351 made on both days and you get $243 made on Tuesday.

3. The equation is now the unknown number of units sold (x) times the price ($120) times the commission is decimal form (.225) equals $243.

4. Since 120 times .225 is equal to 27, the equation now becomes 9x is equal to 243.

5. Divide 243 by 27 for your answer.

Step-by-step explanation:

Answer:

The common ratio is -2.5

The next three terms are;

-125, 312.5 and -781.25

Step-by-step explanation:

Here, firstly we want to determine the common ratio

To

do this, we have to divide the succeeding term by the preceding term

We have this as;

50/-20 = -20/8 = -2.5

Now, to get the next terms,

we multiply the given last term by the common ratio

That will be;

50 * -2.5 = -125

next is to multiply this by the common ratio

That will be;

-125 * -2.5 = 312.5

And lastly, we have

312.5 * -2.5 = -781.25

Answer:

The Answer Is A.

Step-by-step explanation:

Answer: 11,700 times

Step-by-step explanation:

First find the number of seconds in 3 minutes 15 seconds.

Each minute is 60 seconds so 3 minutes would be:

= 3 * 60

= 180

Add the 15:

= 195 seconds

Lightning strikes more than 60 times per second so we shall use 60 times

= 60 * 195

= 11,700 times
