On the Cartesian plane, the midpoint between two points $A(a,b)$ and $B(c,d)$ is $M(m,n)$. If $A$ is moved vertically upwards 8 units and horizontally to the right 2 units, and $B$ is moved vertically downwards 2 units and horizontally to the left 10 units, then the new midpoint between $A$ and $B$ is $M'$. What is the distance between $M$ and $M'$?

Answers

Answer:

5

Step-by-step explanation:

The distance between M and M' is 5 units in the cartesian plane.

What is Distance?

The length along a line or line segment between two points on the line or line segment.

The midpoint M of A(a,b) and B(c,d) is given by:

M(a+c/2, b+d/2)

After the two points are moved, the new coordinates are A'(a+2,b+8) and B'(c-10,d-2).

The new midpoint M' of A'(a+2,b+8) and B'(c-10,d-2) is given by:

M'(a+2+c-10/2 , b+8+d-2/2)

M'(a+c-8/2 , b+d+6/2)

To find the distance between M and M', we can use the distance formula:

d(M,M')=√((a+c)/2 - (a+c-8)/2)²+((b+d)/2-(b+d+6)/2)²

=√4²+(-3)²

=√16+9

=5 units

Hence, the distance between M and M' is 5 units.

A hailstorm caused damage at a car lot. A compact car usually sells for
$27,500, but the damaged cars are discounted to $17,875. What was the
percent discount on a damaged compact car?

Answers

Answer:

$655.61 is the new price. it was decreased in price by 65%

Step-by-step explanation:

A percentage is a number or ratio that can be expressed as a fraction of 100.

The percent discount on a damaged compact car is 35%.

What is a percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100.

We have fractions for different percentages.

50% = 1/2

20% = 1/5

25% = 1/4

10% = 1/10

We have,

The selling price of the compact car = $27,500

The discounted price of the damaged compact car = $17,875

The discounted percentage of the car:

= (27,500 - 17,875) / 27,500 x 100

= 9625 / 27500 x 100

= 35%

Thus the percent discount on a damaged compact car is 35%.

P.S. This is a percent increase/decrrease
from: 9559
to: 8500

%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)

m = 180°–28°–57°

m = 95°

9) m∆4 + m∆5 = 180°

Last year, the hiking club had 25 members. This year, there’s 37. What is the percent increase?

Answers

Answer:

The hiking club's member count increased by 48%.

Step-by-step explanation:

We are given two data values: 25 members and 37 members. We need to determine how many members the club gained first. We can set up an equation where we solve for an unknown, or x, in this case.

[tex]25 + x = 37\\\\x = 12[/tex]

The club increased by 12 members, so now we can divide this value by the initial amount of members and multiply the decimal we receive by 100 to express it in percentage form.

[tex]\frac{12}{25} =0.48\\\\0.48 \times 100 = 48\%[/tex]

Therefore, the club's member count increased by 48%.

Answer:

25+12=37

There would be 48%.

Step-by-step explanation:

If you go down 1/2 and right 5, you get to M. If you go another 1/2 down and right 5, you will get to B.

This is because M is the midpoint, or center point, of line AB. That means there is equal distance going from A to M and equal distance going from B to M.

Given:

Predicted value of rain = 28 mm

Actual amount of rain = 35 mm

To find:

The percent error.

Solution:

We know that,

[tex]\text{Percent error}=\dfrac{\text{Predicted value - Actual value}}{\text{Actual value}}\times 100[/tex]

On substituting the values, we get

[tex]\text{Percent error}=\dfrac{28-35}{35}\times 100[/tex]

[tex]\text{Percent error}=\dfrac{-7}{35}\times 100[/tex]

[tex]\text{Percent error}=\dfrac{-1}{5}\times 100[/tex]

[tex]\text{Percent error}=-20\%[/tex]

Therefore, the percent error is -20%.

Answer:

Step-by-step explanation:

The 2 angles are adjacent and supplementary, thus

2x + x + 84 = 180 , that is

3x + 84 = 180 ← required equation

Subtract 84 from both sides

3x = 96 ( divide both sides by 3 )

x = 32

Thus

∠ 1 = 2x = 2(32) = 64°

∠ 2 = x + 84 = 32 + 84 = 116°

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?

Answers

Answer:

It is wrong because she should simplify both sides of the equation,distribute, combine like terms,subtract and divide to get the final answer.

4x−2(3x−4)+4=−x+3(x+1)+1

Step 1: Simplify both sides of the equation.

4x−2(3x−4)+4=−x+3(x+1)+1

4x+(−2)(3x)+(−2)(−4)+4=−x+(3)(x)+(3)(1)+1(Distribute)

4x+−6x+8+4=−x+3x+3+1

(4x+−6x)+(8+4)=(−x+3x)+(3+1)(Combine Like Terms)

−2x+12=2x+4

−2x+12=2x+4

Step 2: Subtract 2x from both sides.

−2x+12−2x=2x+4−2x

−4x+12=4

Step 3: Subtract 12 from both sides.

−4x+12−12=4−12

−4x=−8

Step 4: Divide both sides by -4.
