1. The blades of a ceiling fan rotate about a circle of 113 inches. What is the most likely length of a ceiling fan blade?
a. 24 inches
b. 18 inches
c. 36 inches
d. 12 inches

Answers

So, this question is like finding the radius given the circumference.
Circumference is 113, and the formula to find the radius is $r = C/2 \pi$
$r = 113/2 \pi$

R ≈ 17.98
So, the most likely length of of the blade would be B) 18 inches.

It should be about 18 inches

Whats 7630918 to the nearest 1000

Answers

7630918 rounded to the nearest 1000 is 7,631,000

The nearest 100 is the third digit in a number to the left of 0. In this case, that number is 9. If the number after 9 was greater than 4, the 9 would be rounded up. However, because 1 is less than 5, the 9 remains the same.

The answer is 9630900.

Joyce baked a cake using 2 3/4 cups of brown sugar and 1 3/4 cups of powdered sugar. How many cups of sugar did she use in her cake? (Answers above in photo)

Answers

So she has used two kinds of sugar, brown and powdered.

She used $2 (3)/(4)$ cups of brown sugar and $1 (3)/(4)$ cups of powdered sugar: we need to add the two numbers:

$2 (3)/(4)$ + $1 (3)/(4)$ = 2+1+ $(3)/(4)+ (3)/(4)$ =3 $(6)/(4)=3+1+ (2)/(4) =4 (2)/(4)=4 (1)/(2)=4.5$

so the correct answer is 4.5

Create a equation using this graph?

Answers

The formula for a straight line is y=mx+b, where m is the slope and b is the y-intercept.

To find out the slope, we use a formula known as rise/run.

Rise means how high a point goes between any two points and run is how far the space is between any two points.

We can see that there are two points give to us. Now we ask our self how high do we have to go to reach the second points’ height. If we count it we go five UP. Meaning that the rise is positive 5.
Now we see how far the two points are. If we count it, we go 1 space the LEFT meaning -1 since going left on a graph means x is getting smaller.

Now that we have he two values, we put them into rise/run

5/-1=-5

So our value of m is -5
Meaning y=-5x+b

We still have our value of b to find and we can do this by choosing any one point on the graph and substituting it into the equation. We know that one of our points is (3,0)

We put these into the equation

y=-5x+b
0=-15+b
b=15

Therefore, y=-5x+15
