if 6 = 68 degrees, find the measures of angles 4, 5 ,7

Answer:

y=6x+28

Step-by-step explanation:

Using the given variables, find the equation of the line using y=mx+b

In this equation, m=slope, which means m=6

So now we have y=6x+b. We need to find the b value.

Plug in the point (-4,4) into the equation and solve for b like so:

y=6x+b

4=6(-4)+b

28=b

Now, plug in your m value and b value into y=mx+b to get your answer of y=6x+28

Answer:

well, we only no that

2l + 2w is 80

(lengths and widths on all 4 sides

and that w * l is A

so the function should be w times what's left for l, but also expressed by something with w

2l + 2w = 80 | -2w

2l = 80 -2w | devide by 2

l = 80 - w

now we can substitute l in

A = w * l

so that we only need w's

A(w) = w * (80-w)

for any w it will give us the area, makes only sense for 0<w<80

Answer:

-18

Step-by-step explanation:

fog(x) = -9(x-9) -9

=> f o g (10) = -9(10-9)-9 = -9-9 = -18

Answer:

x = 11

Step-by-step explanation:

<4 and <5 are alternate interior angles and alternate interior angles are equal when the lines are parallel

<4 = <5

7x+5 = 5x+27

Subtract 5x from each side

7x+5-5x = 5x+27-5x

2x+5 = 27

Subtract 5 from each side

2x+5-5=27-5

2x =22

Divide by 2

2x/2 =22/2

x =11

Answer:

-x-6=y

Answer:

Determine the equation of the line perpendicular to the line y = –8 through the point (–4, –2).

The line y = –8 is

✔ horizontal

The line perpendicular to the line y = –8 is

✔ vertical

i got it right

I-moom equation is 12x+3

I-toons equation is 10x+9

This is the same as 7.5pi

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

Explanation:

Refer to the previous post I answered a while back. It's a similar problem, just with different numbers.

Instead of following that exact route, I'll use a more direct route this time. I'll use the formula below

S = (x/360)*pi*r^2

where S is the area of the sector (aka pizza slice), x is the angle of the sector, and r is the radius.

Notice the x/360 portion represents taking a fractional part of the full circle area pi*r^2

-----------------------

Plugging in the given values leads us to...

S = (x/360)*pi*r^2

S = (108/360)*pi*5^2

S = (3/10)*pi*25

S = (3/10)*25*pi

S = 75pi/10

S = 15pi/2

This is the same as 7.5pi because 75/10 = 15/2 = 7.5

I'll leave it as a fraction since the previous answer I wrote was in fraction form.

-------------------------

Side note: if the angle x is in radian mode, then you'll use this formula

S = (x/2)*r^2

Answer:

7.5π square meters

Step-by-step explanation:

The formula for the area of a sector (when angle is given in degrees) is: [tex]A=\frac{\theta}{360}\pi r^{2}[/tex]

Where r is the radius, and [tex]\theta[/tex] is the angle of the sector in degrees.

We are given the information that the radius = 5m, and [tex]\theta[/tex] = 108 degrees. So now we can just substitute these values into the equation to solve for A:

[tex]A=\frac{108}{360}\pi 5^{2}\\\\A=0.3\pi * 25\\A = 7.5\pi[/tex]

(OR approx. 23.56 square meters)

Answer:

A

radius is 11

diameter is 22

B

radius is 15

diameter is 30

C

radius is 13

diameter is 26

D

radius is 7

diameter is 14

Answer:

Step-by-step explana

1- R == 11

D=2R = 22

2-D =30

R= 0.6D = 15

3- D = 26

R= 0.5D= 13

4 - R= 7

D= 2R = 14

Answer:

A

Step-by-step explanation:

Area of rectangle  = length x width

length = 5x - 2

width = x

area = (5x - 2) × x

100 = 5x² - 2x

the width would be less than the area of the rectangle, thus the inequality sign to be used is <

5x² - 2x < 100

Answer:

[tex]AB = 21.3[/tex]

Step-by-step explanation:

Given

[tex]\sin(25) = \frac{9}{c}[/tex]

See attachment

Required

Find AB

We have:

[tex]\sin(25) = \frac{9}{c}[/tex]

Make c the subject

[tex]c = \frac{9}{\sin(25)}[/tex]

[tex]c = 21.3[/tex]

From the attached triangle;

[tex]AB = c = 21.3[/tex]

Hence:

[tex]AB = 21.3[/tex]

Explanation:

In Venn diagrams, similarities in both things are in the middle of the diagram, but we also have the others.

Therefore, there are 41 students who like tennis and swimming.

Students who don't like tennis like swimming, so that's 17.

Therefore, there are 17 students who don't like tennis.

Answer: {±2√3}

Step-by-step explanation: Since only one term contains an x in this problem, we can simply get the x by itself by dividing both sides by 5 and then square rooting both sides to get x = ±√12

Remember to use plus or minus when

square rooting both sides of an equation.

Now, √12 breaks down to 2√3 so our

final answer is {±2√3}.

If the variable only appears in one of the terms in the equation,

you can solve it by simply isolating the variable.

Answer:

Slope = 3

Step-by-step explanation:

Calculate using slope formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

[tex](x1, y1) = (4, 9)[/tex] and [tex](x2, y2) = (7, 18)[/tex]

[tex]m = \frac{18 - 9}{7 - 4} = \frac{9}{3} = 3[/tex]

Answer:

v=9

Step-by-step explanation:

Given the right triangle is a 30-60-90 triangle, we can simply make the equation v√3=9√3 since the longest side of a 30-60-90 triangle is √3 times as big as its short side. Therefore, v=9.
