The measure of an angle is 112.8°. What is the measure of its supplementary angle?


Im D u m b

Answers

Answer 1
Supplementary angels means that they both add up to 180°. So 112.8+x=180.
So subtract 112.8 from both sides and you get 67.2°. So the answer is 67.2°
Answer 2
If angles X and Y are supplementary
X+Y=90
x=16+3y
16+3y+y=90
4y=90-16
4y=74
y=74/4=18.50
x=90-18.50=71.50

It will take Bridget 8 nights to knit 40 centimeters. You can get this answer because if Bridget knits 15 centimeters in 3 nights then she knits 5 centimeters every night. From then on all you have to do is divide 40/5 to get the answer.

Answer:

y = 0.005x + 20.

Step-by-step explanation:

First, we need to make the equation. We can use y = mx + b.

b is the y-intercept, and in this case, it is 20. Plug it in: y = mx + 20. Our first point on the graph is (0,20).

The slope is 0.005 (y = 0.005x + 20), which is too small to graph, if you look at the x-axis labels. But that's okay! Plug in a number for x that you know is on the x-axis, such as 2,000.

y = 0.005(2000) + 20 = 30

Remembering (x,y), we have our second point on the graph (2000, 30).

Let's look for one more.

y = 0.005(14000) + 20 = 90

Our third point on the graph is (14000, 90).

Now, lets look for those points on the graph and make our line.

what number do you multiply by itself to get 6.25???

Answers

Answer:

2.5

Step-by-step explanation:

The square root of 6.25 is 2.5.

Becuase 2.5 x 2.5 = 6.25

Hope this helps!

Answer:

2.5

Step-by-step explanation:

6.25 = 625/100

625/100 = (5×5×5×5)/(2×2×5×5)

{prime factorisation}

Pairing of common numbers =

{(5×5) × (5×5)}/{(2×2) × (5×5)}

{taking a single no. from the pairs}

= {5 × 5}/{2 × 5}

= 25/10

= 2.5
