Answer:

-2

Step-by-step explanation:

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]

☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.

Given that the two points (-12, 10) and (-10, 6) lie on the line,

slope of the line

[tex] = \frac{10 - 6}{ - 12 - ( - 10)} [/tex]

[tex] = \frac{4}{ - 12 + 10} [/tex]

[tex] = \frac{4}{ - 2} [/tex]

[tex] = - 2[/tex]

Extra:

The line has a negative slope as looking from the left to right, the line is sloping downwards.

8/4= 2

Answer:

Step-by-step explanation:

So we know they had got $22,553 which is 90% more than last year. With this information we know:

190% = $22,553

1% = $22,553/190

1% = $118.70

100% = $11870

So overall it would be $11870 which they had got last year

Answer:

The angle is 50 degrees.

Step-by-step explanation:

In order to measure the angle, you take the three points: F, H, and G, and it forms the angle which is pointing at 50.

Answer:

m=-6/7

Step-by-step explanation:

the formula of a slope is m=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

where [tex]x_{1}=-2,x_{2}=3/2, y_{1}=5, y_{2}=2\\[/tex]

m=(2-5)/(3/2+2)

m=-6/7

V = h··r²

10 × 3.14 = 31.4

31.4 × 5.5² = 949.85

949.85, rounded equals 950

Answer:

probability is 0.67

Step-by-step explanation:

We know that Angle in a circle = 360°

Area of total shaded parts = 60 + 60 = 120°

Area of total unshaded parts = 360-120 = 240°

Probability that a random selected point within the circle falls in the unshaded area

= 240/360

= 2/3= 0.67

Probability that a randomly selected point within the circle falls in the white area will be [tex]0.67[/tex] .

Probability is the ratio of the number of outcomes to the total number of possible outcomes.

Probability [tex]=\frac{Number\ of\ possible\ outcomes}{Total\ number\ outcomes}[/tex]

We have,

Radius [tex]=4[/tex] cm

Now,

Area  of Circle [tex]=\pi r^{2}[/tex]

Area  of Circle[tex]=\frac{22}{7} *4^2=50.28\ cm^2[/tex]

Now,

Area of minor segment [tex]=\frac{\theta}{360^0} *\pi r^{2}[/tex]                                    

Area of minor segment [tex]=\frac{60}{360} *\frac{22}{7}* 4^{2}=8.38\ cm^2[/tex]

Now,

We have two  minor segment,

Area of two minor segment [tex]=8.38*2=16.76\ cm^2[/tex]

Now,

Area of white Portion [tex]=50.28-16.76=33.52\ cm^2[/tex]

Now,

Probability [tex]=\frac{Number\ of\ possible\ outcomes}{Total\ number\ outcomes}[/tex]

Probability [tex]=\frac{33.52}{50.28}=0.67[/tex]

So, the Probability of white area is [tex]0.67[/tex] .

Hence, we can say that Probability that a randomly selected point within the circle falls in the white area will be [tex]0.67[/tex] .

perimeter of square= 4×side

32= 4×side

32/4= side

8= side

hope it helps you friend!!

Answer:

I think what you are asking for is an example.

Step-by-step explanation:

Standard form equation

8x-4y = 20

1. move 8x to the other side

-4y=20-8x

2. divide both sides by -4

[tex]\frac{-4y}{-4} = \frac{20-8x}{-4}[/tex]

3. Solve for this...

y=2x-5

The shape of Joy’s room is a rectangle 540 cm long by 250 cm wide.

a. Work out the area of his room in Square meters.

b. How much does he pay to buy flooring for his room where flooring costs $ 40 per square meter

Work out the area of his room in Square meters.

We know that:-

Area of a rectangle = (length × breadth)sq.units

Therefore,

Area of the rectangular room = (5.4 × 2.5) square meters

=> Area of the rectangular room = 13.5 square meters.

Area of his room is 13.5 square meters.

How much does he pay to buy flooring for his room where flooring costs $ 40 per square meter

Flooring cost in 1 squre meter = $40

Flooring cost in 13.5 square meters = $(40 × 13.5) = $540

He pays $540 to buy flooring for his room.

Hope this helps you!! (^_^)

Answer:

B

Step-by-step explanation:

Since the triangle is isosceles, then the segment from the vertex is a perpendicular bisector and the triangle is divided into 2 right angles with legs 12 and [tex]\frac{1}{2}[/tex] x with hypotenuse 15

Using Pythagoras' identity in the right triangle

( [tex]\frac{1}{2}[/tex] x )² + 12² = 15²

[tex]\frac{1}{4}[/tex] x² + 144 = 225 ( subtract 144 from both sides )

[tex]\frac{1}{4}[/tex] x² = 81 ( multiply both sides by 4 to clear the fraction )

x² = 324 ( take the square root of both sides )

x = [tex]\sqrt{324}[/tex] = 18 → B
