Answer:
1512
Step-by-step explanation:
18 times 21 times 8 = 3024
since it's a triangular prism, u half it
3024 div 2 = 1512
Answer:1,0.5, or 0 it depends
Explanation:
The probability that one event occurred depends on the total of random event, being 1 the most of the probabilities
If the two marbles are blue the probability to select a marble blue is 1
If one of the marbles is blue and the other marble is of any color the probability to select the blue marbles is:
P=1 - 1/2=1/2
Being 1/2 or 0.5 the answer
If any of the marbles are blue then the probabilities are 0
Answer:
$52.03
Step-by-step explanation:
1. Approach
To solve this problem, first one needs to calculate the sales tax, then one must add that to the amount spent on the purchase. To calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
2. Find the tax
As states above; to calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
<u>a. convert percent to decimal</u>
8.4 / 100 = 0.084
<u>b. multiply the decimal by the amount spent</u>
48 * 0.084 = 4.032
The amount spent on sales tax is, $4.032
3. Find the total amount spent
Now all one has to do is add the amount spent in tax by the amount spent on the purchase.
48 + 4.032 = 52.032
Since money is only spent rounded to the second decimal point, one has to round the number;
52.03
