Answer:

-6m^2 *n^2

Step-by-step explanation:

formula: (m^x)/(m^y)= m^(x-y)

apply formula for (4m^2)/(2m^-3)

=(4m^(2--3)/(2)

=4m^5/2

divide 4/2

=2m^5

next part 3n^5/(-mn)^3

3n^5/(-mn)^3

expand

=3n^5/ (-m^3*n^3)

=3n^(5-3)/ -m^3

=3n^2/ -m^3

both parts:

(2m^5* 3n^2)/ -m^3

= -(2m^5* 3n^2)/ m^3

= -(2m^(5-3)* 3n^2)/ 1

= -(2m^2* 3n^2)

= -(6m^2*n^2)

= -6m^2 *n^2

Step-by-step explanation:

The equation that represents the width of the rectangle will be 2(L + W) = 80. And its width is 28 inches.

Let W be the rectangle's width and L its length.

The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be

Perimeter of the rectangle = 2(L + W) units

The perimeter of a rectangle is 80 inches. The length of the rectangle is 12 inches. Then the equation is given as,

2(L + W) = 80

2(12 + W) = 80

12 + W = 40

W = 40 - 12

W = 28 inches

The equation that represents the width of the rectangle will be 2(L + W) = 80.

Answer:

y = 3x

Step-by-step explanation:

When y = 12, x = 4

When y = 0, x = 0

The y intercept is zero.

The easiest point to see clearly is (4,12)

m = y / x because the y intercept is 0

m = 12/4 = 3

The equation of the line is

y  = 3x which is the last one.

Answer: 1. Angle MHG 2. Angle LHM 3. Angle LHK and KHJ and the measures are 35 each

Step-by-step explanation:

1. The order you put the angle points in isn’t super important, as long as the middle point of the angle stays between the two letters, so angle ABC can be angle CBA as long as the b stays in the middle

2. You can find out the LHM is a right angle by looking at the protractor and counting

3. Congruent = Equal and both angles equal 35 degrees.

Answer:

1. Acute Angle

2. MHL

3. LHK and KHJ

Step-by-step explanation:

1. Since GHM has an angle less than 90˚ it is an acute angle

2. MHL is an Right Angle as 110-20 is 90˚ and an right angle is 90˚

3. LHK and KHJ both has an angle of 35˚

If both cyclists travel for the same time and speed, they will have travelled the same distance.  Since one is headed north and the other east, we can see that the distance between them in one hour is the hypotenuse of a right triangle.  Each leg has distance x.  We can say x^2 + x^2 = (3[tex]\sqrt{2}[/tex])^2

2x^2 =1 8

Step-by-step explanation:

12.5x + 30 = -7.5x + 90.5.

20x =60.5

x = 3 1/5

The sales from a music event comes from x tickets sold, at $12.50 a ticket, plus a rental income fee of $30 for an advertising billboard behind the stage.

The cost of the performance includes a musician's fee of $7.50 per ticket sold, plus a $90.5 rental fee for the stage.

The equation will tell us the number of tickets, x, that must be sold to break even (Inclome on the left and expenses on the right).

We need to sell at least 3 1/5 tickets to break even.  It's going to be close.

The equation 12.5x + 30 = -7.5x + 90.5  used to determine the point in time (number of weeks) at which their combined savings and spending will equal the cost of the trip.

The equation 12.5x + 30 = -7.5x + 90.5 could represent their financial situation.

The variable "x" represents the number of weeks they have been saving money.

The term 12.5x represents the total amount of money Friend A has saved over "x" weeks at a rate of $12.5 per week.

The term -7.5x represents the total amount of money Friend B has spent over "x" weeks at a rate of $7.5 per week (which is subtracted since it's being spent).

The constants 30 and 90.5 represent initial savings and the total funds needed for the trip, respectively.

The null hypothesis is the one in which any statement which is the claim of the experiment is chosen to decide the results for .

The alternate hypothesis is the opposite of the null hypothesis.

Type I Error:  Type I Error occurs when H0 is true but it is rejected and Ha is accepted.

Type II Error:  Type II Error occurs when Ha is true but it is rejected and the false null hypothesis H0 is accepted which is wrong decision.

In this case the null hypothesis is

H0: On pulling the rip cord the parachute will open.

Ha: On pulling the rip cord the parachute will not open.

In this experiment the alternate hypothesis Ha :On pulling the rip cord the parachute will not open is accepted then type I error occurs.

In this experiment the null hypothesis H0 :On pulling the rip cord the parachute will not open is accepted then type II error occurs.

In this experiment Type I Error is a more serious error because the true null hypothesis H0: the parachute will open is rejected.

In this experiment Type II Error is a more serious error.

Type I and Type II Errors are independent of the confidence interval.

When the parachute has a backup in case of ripcord malfunctions then the confidence level of the hypothesis can be 100 percent. That is we are 100 percent sure that the parachute will land safely and there will be no accidents.

This is does not guard the type I and type II errors because these are made on the wrong decision.

Answer:

  (-4, 0)

Step-by-step explanation:

The midpoint M of segment AB is found by averaging the coordinates of the end points:

  M = (A +B)/2

Solving this for point B, we find ...

  2M = A +B

  2M -A = B

Then the other end point is ...

  2(2, -4) -(8, -8) = (4 -8, -8 -(-8)) = (-4, 0)

The other end point is (-4, 0).

x to \frac{4x}{15}

4x \frac{4x}{15}=1.44

4x =1.44

2 Multiply both sides by 1515.

4x=1.44\times 15

4x=1.44×15

3 Simplify 1.44\times 151.44×15 to 21.621.6.

4x=21.6

4x=21.6
