Answer:

C) 10.92

Step-by-step explanation:

A= 1/2bh

A = 1/2(2.8)(7.8)

A= 1/2(21.84)

A = 10.92

Answer:

C. 10.92^2

Step-by-step explanation:

Area of triangles can be solved using: 1/2*b*h

1/2*2.8*7.8=10.92

Answer:

Step-by-step explanation:

y = ab^x where 0<b<1 for exponential decay

an example would be y = 3(1/7)^x

Answer: 4(2x - 5)

Step-by-step explanation:

factors of 8 : (2, 2), 2

             20 : (2, 2), 5

Therefore the GCF is 2*2 = 4

8x/4 = 2x and -20/4 = -5

4(2x - 5) = 8x - 20

Answer:

slope is  15/5=3

Step-by-step explanation:

Answer:

what is the question write it in thecomments and ill answer

Answer:

1.) (y+1)+y=-5

2y=-6

y=-3

x+(-3)=-5

x=-2

plug in to check if it works

2.) 2(4y+10)+y=2

9y+20=2

9y=-18

y=-2

x-4(-2)=10

x+8=10

x=2

3.) -5(-y+6)+y=0

5y-30=0

5y=30

y=6

x+(6)=6

x=0

4.) 4=6-2x

-2=2x

x=-1

y=6-2(-1)

y=8

5.) 4x-(8)=4

4x=12

x=3

4(3)-y=4

12-y=4

-y=-8

y=8

6.) 3(y-4)+y=12

4y-12=12

4y=24

y=6

x=6-4

x=2

7.) 5x-2x-6=9

3x=15

x=5

5(5)-y=9

25-y=9

-y=-16

y=16

8.)3(x-6)+x=2

4x-18=2

4x=20

x=5

y-5=-6

y=-1

hope this helped :)) also make sure to plug the x and y back into both equations :))

Answer:

C.) 10,240 cubic feet

Step-by-step explanation:

We have to first find the area of the base by multiplying 32 by 32. 32 * 32 is equal to 1024. Next, we multiply by the height divided by 3. 30/3 is equal to 10, so the total volume is equal to 1024 * 10, which is 10240.

Answer:

f(x)^-1=x-2/10

Step-by-step explanation:

Answer:

Slope = 0

Step-by-step explanation:

Given the pair of points: (-3,2) (7,2)

Slope formula: y2-y1/x2-x1

2-2/7-(-3) = 0/10

0/10 = 0

Answer:

Option B

Step-by-step explanation:

When you put option b in y intercept form, the slope is -3/2 which is the negative reciprocal of  2/3, making the lines perpendicular.

3x + 2y = -4

-3x           -3x

2y = -3x -4

/2       /2

y = -3/2 -2

Answer:

190π (not part of the answer choices)

Step-by-step explanation:

The surface area of a cylinder can be found using the formula below:

[tex]SA=2\pi r^2+\pi dh[/tex] where [tex]r[/tex] is the radius of the base, [tex]d[/tex] is the diameter of the base and [tex]h[/tex] is the height of the cylinder.

Plug in the given values

[tex]SA=2\pi (\frac{10}{2}) ^2+\pi (10)(14)\\SA=2\pi (\frac{100}{4})+140\pi\\SA=2\pi (25)+140\pi\\SA=50\pi+140\pi\\SA=190\pi[/tex]

Therefore, although this answer isn't one of the choices, the surface area of the cylinder is 190π.

I hope this helps!

Answer:

11=x

Step-by-step explanation:

since the lines are parallel the distances between each section of line is proportional to each other.

5/6=(x-1)/12

multiply both sides by 12

12(5/6)=(x-1)12/12

10=(x-1)

add 1 to both sides

10+1=x-1+1

11=x

I hope that helps :)

Answer:

c) slope: -7 ; y-intercept: 2

Step-by-step explanation:

Note the slope intercept form:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

Note in this case:

y = (-7)x + 2

y = y

m = -7

x = x

b = 2

c) slope: -7 ; y-intercept: 2 is your answer.

Answer:

=−259x−2y+24

Step-by-step explanation:

Distribute:

=−12x+4y+−6y+10x+−255x+(−2)(x)+(−2)(−12)

=−12x+4y+−6y+10x+−255x+−2x+24

Combine Like Terms:

=−12x+4y+−6y+10x+−255x+−2x+24

=(−12x+10x+−255x+−2x)+(4y+−6y)+(24)

=−259x+−2y+24

Answer:

=−259x−2y+24

Hope this helps emmy! or emma

Answer:

112

Step-by-step explanation:

Divide 1111 By 999 and you get 1.1121121121121

So 112 is repeating over and over in the decimal.

112 is repeated  4 times and starts to repeat again.

Hope that helps!

Answer:

the answer is 66°

Step-by-step explanation:

As it is given that triangle ABC is similar to triangle DEF so

< A = < D ( being corresponding angles of similar triangles)

3x + 18° = 4x + 2°

4x - 3x = 18° - 2°

x = 16°

So now

< A = 3 * 16° + 18° = 66°
