$1,210.00

$1,315.00

Answers

Answer:

$1,210

Step-by-step explanation:

$28,000 - $2,100 = $25,900

$25,900 - $5,000 = $20,900

1.5% × $1,000 = $15

3% × $2,000 = $60

4.5% × $2,000 = $90

5% × $20,900 = $1,045

$15 + $60 + $90 + $1,045 = $1,210

What is the value of x?

Answers

Step-by-step explanation:

2 things to remember :

1. the sum of all angles in a triangle is always 180°.

2. the sum of all angles around a single point on one side of a line is also 180° (because the line can be seen as the diameter of a circle, the point as its center, and so every side of the line is a half-circle = 180°).

so, the third, unnamed angle in the triangle is the supplementary angle to 142° (that means they complete each other to full 180°).

it is therefore

180 - 142 = 38°

and then, inside the triangle

180 = 66 + x + 38 = 104 + x

x = 76°

Tell whether the figure is a polygon. If it is a polygon,
classify it and tell whether it is convex or concave.

Answers

Answers:

Polygon? YesClassify: PentagonThe polygon is concave

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

Explanation:

The figure is a polygon because it's composed of straight lines only, and we have a closed loop (or enclosed area).

This is a pentagon since it has 5 sides

The pentagon is concave because of the angle kicked in up top that caves in, so to speak. This interior angle exceeds 180 degrees and is known as a reflex angle.

Here's another way to determine the figure is concave: It's possible to pick two points inside the polygon such that the segment formed between them crosses outside the boundaries. See the diagram below.

from here i gave them random ages starting at 12(age doesn’t matter because they would be the same age either way just because of the years apart). lamoie is the oldest, so going down from his group is 12,11,10.
conor is 2 years younger than him, so that makes him 10. and we know caleb is the youngest of his group, so going down my two is 10,8,6. conor is 10 and colin is 10.

if 60% of a number is 120 and 25% of the same number is 50 find 85% of that number
PLEASE HELP!
CORRECT= BRAINLIEST

Answers

Answer:

85% of 200 = 170

Step-by-step explanation:

Method

Let the number = x

60/100 * x = 120

0.6 x = 120                  Divide by 0.6

0.6x/0.6 = 120/0.6    

x = 200

25% x = 50                  Convert 25% to a fraction

25/100 x = 50

0.25x = 50                  Divide by 0.25

0.25x/0.25 = 50/0.25

x = 200

85% 200 = x               Change 85% to a fraction

85/100 * 200 = x        Multiply 85 and 200 together

17000 /100 = x          Divide by 100

170 = x

Answer

85% of 200 = 170

Answers

Step-by-step explanation:

the slope-intercept form is

y = ax + b

"a" is the slope (the slope is in all forms the factor of x). and "b" is the y-intercept (the y value when x = 0).

so the first equation is

y = -5x + b

b we get by using the point coordinates :

-22 = -5×5 + b = -25 + b

b = 3

so, the full equation is

y = -5x + 3

for the second equation we need to calculate the slope first. remember, it is the ratio "y coordinate change / x coordinate change" :

x changes by +1 (from -4 to -3).

y changes by +7 (from -2 to 5).

the slope is +7/+1 = 7/1 = 7.

the equation looks like

y = 7x + b

again, we use the coordinates of a point to get b. I picked (-4, -2) :

-2 = 7×-4 + b = -28 + b

b = 26

and the full equation is

y = 7x + 26

On a standardized exam, the scores are normally distributed with a mean of 21 and a

Answers

The Z score is -2 if the standardized exam, the scores are normally distributed with a mean of 21 and a standard deviation of 4.

What is a normal distribution?

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have:

u = 21

SD = 4

X = 13

[tex]\rm Z = \dfrac{13-21}{4}[/tex]

Z = -2

Thus, the Z score is -2 if the standardized exam, the scores are normally distributed with a mean of 21 and a standard deviation of 4.

Answers

The slope of line PO and MN is 0.5. And the slope of the line ON and MP is negative 2. Then each length of the quadrilateral is 4.47 units.

What is a quadrilateral?

It is a quadrilateral with four sides. The total interior angle is 360 degrees.

The points M(−7,2), N(−3,4), O(−5,8), and P(−9,6) form a quadrilateral.

Then the slope of each line of the quadrilateral will be

The slope of the line PO will be

PO = (8-6)/(-5+9)

PO = 2/4

PO = 0.5

The slope of the line ON will be

ON = (8-4)/(-5+3)

ON = 4/(-2)

ON = -2

The slope of the line MN will be

MN = (4-2)/(-3+7)

MN = 2/4

MN = 0.5

The slope of the line MP will be

MP = (6-2)/(-9+7)

MP = 4/(-2)

MP  = -2

Then each length of the quadrilateral will be

The length of PO will be

PO = √[(-9+5)² + (6-8)²]

PO = 4.47

The length of ON will be

ON = √[(-5+3)² + (8-4)²]

ON = 4.47

The length of MN will be

MN = √[(-3+7)² + (4-2)²]

MN = 4.47

The length of MP will be

MP = √[(-9+7)² + (6-2)²]

MP = 4.47
