The measure of Angle B is 68° what is the measure of it supplementary anglea. 22°
b. 90°
c. 112°
d.180°

Answers


"Supplementary angles" means two angles that add up to 180°.

                             (Any angle) + (its supplement)  =  180° .

                                 (Angle B) + (its supplement)  =  180° .

                                        (68°) + (its supplement)  =  180°

Subtract (68°) from each side:        Its supplement = 180° - 68°

                                                                              =  112° .

Hi

A = 180º-B
A = 180º-68º
A = 112º

Answer: c) 112º

Help meh PleAse Which function has the greatest rate of change?

A. 14x – 2y = 8

B. y = 6x – 5

C.
x y
−2 −7
−1 −2
0 3
D.
The Graph is Letter D.

Answers

Rate of Change is the same as Slope.

A.

\sf14x-2y=8

Convert to slope-intercept form.

Subtract 14x to both sides:

\sf-2y=-14x+8

Divide -2 to both sides:

\sf~y=7x-4

So the rate of change here is 7.

B.

\sf~y=6x-5

This is already in slope-intercept form, so the rate of change here is 6.

C.

Take any two points on the graph and plug them into the slope formula.

Let's take (-1, -2) and (0, 3).
               x1  y1        x2 y2

\sf~m=(y_2-y_1)/(x_2-x_1)

Plug in the numbers:

\sf~m=(3-(-2))/(0-(-1))

Subtract:

\sf~m=(5)/(1)

Divide:

\sf~m=5

So the rate of change here is 5.

D.

Take any two points on the line and plug them into the slope formula.

Let's take (0, -2) and (1, 3)
               x1 y1        x2 y2

\sf~m=(y_2-y_1)/(x_2-x_1)

Plug in the numbers:

\sf~m=(3-(-2))/(1-0)

Subtract:

\sf~m=(5)/(1)

Divide:

\sf~m=5

So the rate of change here is 5.

Therefore, A has the greatest rate of change.

Use a common denominator write an equivalent fraction for each fraction2/5 and 1/8 wats the common denominator

Answers

The common denominator of 5 and 8 is forty. 
To go about solving this, do this:
2/5 and 1/8
2*8/5*8 and 1*5/8*5
16/40 and 5/40
Hope this helps!! :)
The common denominator would be 40.
You need to multiply 2 by 8, and 5 by 8 to get 16/40.
Then you need to multiply 1 by 5, and 8 by 5 to get 5/40.
The final answers are 2/5 = 16/40 and 1/8 = 5/40.

ILL MARK YOU AS BRAINLIEST, RATE YOU A 5, AND THANK YOU! 70 POINTS!what is the surface area of this rectangular prism? i-ready

Answers

Answer:

290 in²

Step-by-step explanation:

From the net:

S.A. = 2(25 in²) + 4(60 in²) = 50 in² + 240 in² = 290 in²

From the model:

The formula of a Surface Area of a rectangular prism:

S.A. = 2(lw + lh + wh)

l - length

w - width

h - height

We have l = 5 in, w = 5 in, and h = 12 in. Substitute:

S.A. = 2(5 · 5 + 5 · 12 + 5 · 12) = 2(25 + 60 + 60) = 2(145) = 290 in²

Answer: 290 in.^2
