Answer:
She spent 4 $10 bills and 3 $1 bills
Step-by-step explanation:
She used 7 bills and you have 3 $1 that makes the 3 of 43 then 4 $10 bills adds up to 40 so add 40 and 3 together you get the price of the shoes and if you add the 4 $10 bills and the 3 $1 bills you get 7
<u>Answer:</u>
Bobby could make into 5 holes out of 50 holes in miniature golf .
<u>Step-by-step explanation:</u>
Bobby has experimental probability that he will make a hole-in-one on any hole of a miniature golf course is 10%, i.e. If there is a miniature golf of 100 holes bobby could make into 10 goals. Probability is<em> 10%</em> i.e.<em> 1/10</em>
According to question, Bobby plays 50 holes of miniature golf :
No. of goals he could make = ( No. of holes ) × probability<em>⇒ 50× (1/10) </em>
∴ No. of goals he could make <em>⇒</em><em> 5</em>
Answer:
1,000,000,000 identification numbers are possible.
Step-by-step explanation:
We are assigned a 9 digit identification number.
Each digit is a number from 0 to 9. So, each digit has 10 different choices.
Using the Fundamental Counting Principle (is better than the tree diagram) because it's simpler. To illustrate this, we can attempt to draw a tree diagram.
The first column will be the digits 0 to 9.
Then for each of those digits, we need another 0 to 9.
As you can imagine, the amount of numbers grow exponentially, so using the Fundamental Counting Principle is simpler.
And since we have a 9 digit identification number, with each digit having 10 choices, the total number of identification numbers possible are:
So, 1,000,000,000 identification numbers are possible.

Answer:
310 calories (120 from fat)
Step-by-step explanation:
A 12-inch pizza has double the diameter of the 6-inch pizza, so will have 2² = 4 times the area. 1/8 of that pizza will have 4/8 = 1/2 the area of the personal pizza. If calories are proportional to the area, then the slice will have ...
(1/2)(620 calories) = 310 calories . . . in 1 slice of 12-in pizza
