6 Books
$77.49 is the Total.
$3.99 is the Shipping.
$12.25 is the cost of each individual book.
First find the difference between the total and the shipping.
$77.49 - $3.99 = $73.50
Then divide the product with the cost of each book.
$73.50 ÷ $12.25 = 6 Books
9 out of 12 = 9/12 which can be simplified to 3/4. So the team wins 3/4 of its games. 3/4 of 64 = 64 divided by 4 = 16. 16 x 3 = 48.
Answers:
- Choice C) the number of hours the barn is rented
- Choice B) 10
- Choice A) the hourly rate
- Choice C) 550
- Choice B) the base fee to rent
- Choice A) The variable y
- Choice D) total amount charged
========================================================
Explanation:
The equation is y = 10x+550
If x = 0, then it leads to y = 550. This is the smallest amount paid, and it's the base fee. Think of it like the fee to get in the door. This is the y intercept of the equation.
On top of this base fee is the $10 per hour fee for utilities. Each time an hour goes by, add on another extra $10. So we attached x to this to reflect what's going on. This is the slope of the equation, aka rate of change.
It might be helpful to compare y = mx+b to y = 10x+550
m = 10 = slope = how things change
b = 550 = y intercept = starting point
----------
Example:
Let's say you rented the barn for 2 hours.
That means x = 2 and 10x = 10*2 = 20 extra dollars is added on top of the base fee of $550
total = 20+550 = 570
This is what the steps could look like when plugging in x = 2
y = 10x+550
y = 10*2 + 550
y = 20 + 550
y = 570
Therefore, renting the barn for x = 2 hours leads to a total cost of y = 570 dollars.
Answer:
1/10 and C
Step-by-step explanation:
You wouldn't have a 9/10 because that is too high. It can't even possibly be 3/10. You have a 2/5 chance of getting one grape treat. Then, it would become 1/4 chance. That would make the chances of getting both very small. 1/10th is the only reasonable one.
There is only 2 choices that it can land on. That means it would be half chance of getting either. Only 0.5 or C is 1/2 or 0.5 of half.
Answer:
1/50
Step-by-step explanation:
Probability that both engines fail = Failure rate of both engines
= 1/100 + 1/100
= 2/100
= 1/50
