Answer:

16 times out of 64

Step-by-step explanation:

So, I could be wrong, but basically:

9, 10, and 11 are only 3 of the 12 possible outcomes that could happen.

3 out of 12 is 1/4.

What this means is that for every 4 times he spins the pointer, he can expect to get 9, 10, or 10 once.

Or 25% of the time

1/4 of 64 is 16.

To determine a monthly budget for gasoline, Rachael determines that she can not spend more
IrinaK [193]

The solution of the given inequality is:

x ≤ 15.24

<h3>How to solve the inequality?</h3>

We know that the maximum that she can spend on gasoline is the 12% of $400.

That is:

(12%/100%)*$400 = 0.12*$400 = $48

Now, we know that each gallon of gas costs $3.15, then if x is the number of gallons of gas that she buys, we have the inequality:

x*$3.15 ≤ $48

To solve the inequality, we need to divide both sides by $3.15

x ≤ $48/$3.15

x ≤ 15.24

So the maximum number of gallons of gasoline that she can buy is 15 gallons (actually a little more).

Peter spent half the money on his gift card and coffee and he loaded another $10 on the gift card how much was on the gift card
cestrela7 [59]

Answer:

$80 was on the gift card to begin with

Step-by-step explanation:

Let the initial money be x

Peter spent (1/2)*x

Peter added 10

<em>Before adding more money on the gift card Peter had x -(1/2)x left on the gift card which is (1/2)x</em>

<em>After loading more money Peter had (1/2)x + 10</em>

(1/2)x = 40 <em>(money spent by Peter)</em>

x/2 = 40

x = 80
