Answer:

tan G = 1.6071

Step-by-step explanation:

tan G = 45/28

tan G = 1.6071

Step-by-step explanation:

Two angles are called suplementary when their measures add to 180 degrees.

D+F= 180

3x+5+2x= 180

5x+5=180

5x= 175

x= 35°

angle D = 3x+5= 3(35)+5= 110°

Answer:

0.6 + 15b + 4 = 25.6

15b +4 = 25

15b = 25 - 4

15b = 21

b = 21/15

b = 7/5

hope it helps

Answer:

Exact Form:

b=7/5

Answer:

.translation(x, y)  →(x+h, y+k)

reflection of (x,y)→(−x,y) on y-axis

reflection of (x,y)→(x,-y) on x-axis

Answer:      x = -4y + 1

                           3     3

Step-by-step explanation:

3x + 4y = 1

3x + 4y + -4y = 1 + -4y

3x      -4y + 1

3  =         3

   x = -4y + 1

Answer:

A = 1863

Step-by-step explanation:

There are a few ways you could do this but I will do the one I know best.

Keep in mind the area is the L(enght x W(idth) = A(rea)

There are two long rectangles if you cut off the square in the middle so find the area of those two first.

31 x 23 = 713

713 x 2 = 1426 (Did this to get the area for both of them.

Now find the area of the square.

23 x 19 = 437

The you would add them all up together to get 1426 + 437 = 1863

Hope this helps :)

Answer:

1,863

Step-by-step explanation:

ok I will try to explain my answer as easy and under standable as posable.

ok what I did is the left and right side of the building I drew two lines down the middle to crate two huge rectangles on each side and one small rectangle in the middle ok. hope you understand! if you don't click the file down below.

ok after you see the file you will under stand a lot better.

ok

what I did is on the left and right triangle I did 31 tall and 23 wide. what you do I multiply the two numbers.

31 x 23 = 713

then the middle triangle is 23 wide and I did 31 - 12 to get the tall of the triangle since it did not give it to you so I got 19.

so I multiplied 23 by 19 and got 437.

so you adding all three triangles and I get 1,863 by

713 + 713 + 437 = 1,863

hope this helps

Answer:

n = -2

Step-by-step explanation:

[tex] - 6n - 2n = 16[/tex]

➡️ [tex]( - 6 - 2)n = - 8n[/tex]

➡️ [tex] - 8n \div ( - 8) = 16 \div ( - 8)[/tex]

➡️ [tex]n = 16 \div ( - 8)[/tex]

➡️ [tex]n = - 16 \div 8[/tex]

➡️ [tex]n = - 2[/tex]

Answer:

I think its B.) Yes, because the ratios simplify to the same number., sorry if it's wrong

Step-by-step explanation:

50/10 = 1/5

60/12 = 1/5

70/14 = 1/5

80/16 = 1/5

They all simplify to the same proportion.

Answer:

7x minus 11

Step-by-step explanation:

7x would be 7 times whatever x is. then you subtract 11 from 7x. the reason you’re subracting 11 from 7x is because 11 has to be less than 7x (i understand negatives, but we’re not using that in this problem.)

Answer: (B) 7x minus 11

Step-by-step explanation: Just to make sure it was correct!

AB is the diameter, therefore ACB is right angle

Correct option is A

Answer:

m = 10

Step-by-step explanation:

The values of w is inversely proportional to m

Mathematically the above statement is expressed as:

w ∝ 1/m

w = k × 1/m

w = k/m

Where k is the Proportionality Constant

First step

Solve for k

If w=8 then m=25

w = k/m

8 = k/25

Cross Multiply

k = 25 × 8

k = 200

Second step

what is m when w=20? Show me the steps please

We solve for m

w = k/m

k = 200

20 = 200/m

Cross Multiply

20m = 200

m = 200/20

m = 10

Answer:

y=-4x+4x-32

Step-by-step explanation:

Answer:

y=x-8

Step-by-step explanation:

4y-4x=-32

4y=4x+(-32)

4y=4x-32

y=4/4x-32/4

y=x-8

Answer:

Non-linear

Step-by-step explanation:

If we were to graph this table, the points will form a curve.

This is most likely a exponential function, not a linear function.

A linear function would form a straight line on a graph.
