Answer:

126

Step-by-step explanation:

131 + - 5 can either be;

131 + 5 = 136

131 - 5 = 126

The question is probably asking what is 131 plus negative 5, hence the correct equation is; 131 - 5, and the correct answer is 126.

Answer:

[tex]Height = 15[/tex]

[tex]Base = 45[/tex]

Step-by-step explanation:

Given

Shape: Rectangle

[tex]Perimeter = 120cm[/tex]

[tex]Base = 3 * Height[/tex]

Required

Determine the dimensions

The perimeter of a rectangle is:

[tex]Perimeter = 2 * (Base + Height)[/tex]

Substitute 120 for Perimeter

[tex]120 = 2 * (Base + Height)[/tex]

Divide both sides by 2

[tex]60 = Base + Height[/tex]

Substitute 3 * Height for Base

[tex]60 = 3 * Height + Height[/tex]

[tex]60 = 3Height + Height[/tex]

[tex]60 = 4Height[/tex]

Divide both sides by 4

[tex]15 = Height[/tex]

[tex]Height = 15[/tex]

Substitute 15 for Height in [tex]Base = 3 * Height[/tex]

[tex]Base = 3 * 15[/tex]

[tex]Base = 45[/tex]

The length of radius is 7.81 unit.

The distance between two points P(a, b)a nd Q(c, d) is

D = √(c- a)² + (d- b)²

Given:

Center at (-2,7) if a point on the circle has coordinates (3,-1).

Using Distance Formula

D = √( 3-(-2))² + (1-7)²

D = √ (3 +2)² + (-6)²

D = √5² + 36

D = √25+36

D = √61

D= 7.81 unit

Hence, the length of radius is 7.81 unit.

Answer: Consistent (and independent)

Step-by-step explanation:

The meaning of the options are:

Consistent (and independent): There is only one point of intersection between the two lines.

Inconsistent: The lines never touch each other, this only can happen when the lines are parallel, so they have the same slope but a different y-intercept.

Equivalent (also called consistent and dependent): This happens when both lines are the same line, so they intersect in an infinite number of points.

In the graph, we can see that the lines intersect in only one point, then we can conclude that the system is consistent.

Answer:

y is equal to nine and two thirds, or 9.666...

Step-by-step explanation:

To solve this, we first need to know the value of x.  We can see though that x + (x - 12) is equal to 180 degrees, so:

x + 5x - 12 = 180

6x = 192

x = 32

Now that we have x, we can use the same rule to solve for y:

3y - 8 = x

3y - 8 = 32

3y = 40

y = 40 / 3

So y = 40/3, or 9 and 2/3

Bonus:

I almost wonder if the question was printed incorrectly, as the answer would have been a nice tidy integer if the other corner was 3y + 8 instead of 3y - 8.

If that were the case we'd have:

3y + 8 = 32

3y = 24

y = 8

A nice clean answer

To be clear, this last bit is NOT the correct answer, just an observation. If the book tells you that eight is the answer, then the question is misprinted.

Answer:

1178 inches

Step-by-step explanation:

Using the triangle I drew (assuming n is across from ∠N), we can conclude that ∠O = 180-97-32 = 51 as the angles in a triangle add up to 180.

Using the law of sines, we can conclude that

[tex]\frac{o}{sinO} = \frac{n}{sinN} \\[/tex]

Plugging our values in, we get

[tex]\frac{o}{0.78} = \frac{800}{0.53}[/tex]

Multiply both sides by 0.78 to get

[tex]o = \frac{800*0.78}{0.53} = around 1177.5[/tex]

round up to get 1178 as our answer

The width of the mat with the given area and length is 7/10 in.

The area of a rectangle is expressed as;

A = l × w

Where l is length and w is width.

Given the data in the question;

We plug our given values into the above equation and solve for w.

A = l × w

7/12 = 5/6 × w

w = 7/12 ÷ 5/6

w = 7/12 ÷ 6/5

w = 42/60

w = 7/10 in

Therefore, the width of the mat with the given area and length is 7/10 in.

Step-by-step explanation:

for each k(x) value, plug the x into the given equation

-4: 1/2 (-4) -1 = -2-1=-3

all are solved this way

-2: -2

0: -1

2: 0

4: 1

ordered pair will be (x, (k(x))

for example (-4, -3)

do this for all other points

slope can be found by taking the change in y over change in x

so -2- -4 divided by -2 - - 3 = 2/1 = 2

slope = 2

Answer:

The length of other wall is 3 meters.

Step-by-step explanation:

Given that:

Length of one wall = 4 meters

Length of diagonal from one corner to opposite corner = 5 meters

As the room is rectangular, the diagonal will form a right angled triangle.

The diagonal will be the hypotenuse.

Using pythagorean theorem;

[tex]a^2+b^2=c^2[/tex]

Here,

a = 4 and c = 5

[tex](4)^2+b^2=(5)^2\\16+b^2=25\\b^2=25-16\\b^2=9[/tex]

Taking square root on both sides

[tex]\sqrt{b^2}=\sqrt{9}[/tex]

b = 3 meters

Hence,

The length of other wall is 3 meters.

Answer:

x = 80

y = 100

Step-by-step explanation:

First, we need to figure out how many degrees there are in total in the inside of the polygon. There are 7 sides, so now let's use the formula to find out the total degrees.

(n - 2) * 180

"n" is the amount of sides.

(7 - 2) * 180 =

5 * 180 =

900

The total degrees is 900.

Now, we have to add all the sides in the inside to form an equation to solve for y.

y + 135 + 140 + 150 + 120 + 135 + 120 = 900

y + 800 = 900

y + 800 - 800 = 900 - 800

y = 100

Now, we know that x and y are supplementary angles. So the sum of x and y is 180. We can use that to create an equation to solve for x!

x + y = 180

x + 100 = 180

x + 100 - 100 = 180 - 100

x = 80

Therefore, x = 80 and y = 100
