Hello!

You add the amount of sections have red or purple

2 + 2 = 4

Put this over the amount of sections

4 / 10 = 0.4

Multiply this by the amount of times he spins the spinner

180 * 0.4 = 72

The answer is about 72 times

Hope this helps!

160 bananas; 20% decrease
Kay [80]
First you turn 20% into a decimal by dividing by 100 and you get .20
then you multiply .20 by 160 and get 32
then subtract:
160-32=128
So if you have 120 bananas and you have a 20% decrease then you would have 128 left over

Hope this helped!! :D

Please help me with this please and thank you
Alina [70]

Step-by-step explanation:

y = ax^n + bx^(n-1) ... + z

(0, 1) tells us that the constant term z = 1.

because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.

for the other pairs I strongly suspect

(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3

(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9

so, the fitting equation is

y = 2x² + 1

If y varies inversely as x and y=3 when x=14, find x when y=6​
alukav5142 [94]
X=7 What you can do is look at the first two values given, and make them x1 and y1. Then your next value here is y2.

So x1 is 14, and y1 is 3. y2 becomes 6. X2 is unknown.

Then make the formula: x1/y2 is equal to x2/y1
(You are setting two fractions equal to each other)

That makes 14/6=X/3. When we cross multiply, we find that x=7.

What is the average rate of change of f(x), represented by the table of values, over the interval [-3, 2]?
maksim [4K]
You would select the points with the x-values -3 and 2 and use the slope formula:
(-3, -36) and (2,4)
m= \frac{y_2-y_1}{x_2-x_1} ← slope formula
x1 = -3 y1 = -36 and x2 = 2 y2 = 4

m= \frac{4--36}{2--3} = \frac{40}{5} =8
