Mrs. Rogers sold 48 out of 80 crafts at the fair. What percent of her crafts did she sell? ~Plz answer like ASAP!!thank you :)) ~

Answers

Answer:

38.4

38.4 is 48% of 80

Step-by-step explanation:

What is 48% of 80?

Y is 48% of 80

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 48% * 80

Converting percent to decimal:

p = 48%/100 = 0.48

Y = 0.48 * 80

Y = 38.4

Find the value of g(4) for the function below:
g(x) = x² – 2x + 5
O 5
O 13
O 19
O 25

Answers

Answer:

O 13

Step-by-step explanation:

g(4) is asking for the function of g when x = 4

g(4) = (4)^2 - 2(4) + 5

g(4) = 16 - 8 + 5

g(4) = 13

PLEASE HELP DUE VERY SOON!

Answers

Answer:

Yes. (see below)

Step-by-step explanation:

First, find the slope of the line. You can do that by using the slope formula:

y2 - y1

m = ----------

x2 - x1

Now, choose any two points from the line to plug in. I'm using the points (0, 3) and (2, 4).

4 - 3

m = ------

2 - 0

m = --- = 1/2

Now, to simplify your situation, you can use the slope-intercept formula. To use this, you first need to find the slope and y-intercept.

The y-intercept is where the line meets the y-axis, which is (0, 3), so the y-intercept is 3.

Now, plug them in:

y = mx + b

y = 1/2x + 3

To see if a specific point is on this line—which, in this case, is (20, 13), plug them in and simplify to see if it's true:

13 = 1/2 (20) + 3

13 = 10 + 3

13 = 13

This is true, so the point (20, 13) is on this line.
