Let's divide the percentage by the number of footballs.
40÷4
10
So every ball is 10 percent of all the balls.
100÷10
10
So there were 10 footballs available.
Answer:
y=3x-1
Step-by-step explanation:
First, we must find the slope of the equation. To do that we take two ordered pairs from the graph.
(2,5) (10,29)
The equation for slope is m=y2-y1/x2-x1
m=29-5/10-2
m=24/8
m=3
Now, we will find the variable B.
5=3(2)+b
5=6+b
-1=b
That's how we get the equation!
y=3x-1
Answer:
2:5
Step-by-step explanation:
The ratio of pair of flip flop to pair of sneakers is 4:10 we simplify it to 2:5 by dividing both sides by 2
Answer:
cos 78⁰.
Step-by-step explanation:
Use cos 2A = cos^2 A - sin^2 A
so cos^2 39 - sin^2 39 = cos (2*39) = cos 78.
