Answer:
13 levels
Step-by-step explanation:
Direct variation can be expressed using the formula:
y = kx, where 'k' is the constant of variation
Since Michael can move up 5 levels in 55 minutes:
n = km, where 'n' is the number of levels and 'm' is the number of minutes:
5 = 55k
k = 1/11
To find the number of levels after 143 minutes:
n = (1/11)(143)
n = 13 levels
Answer:
1.08%
Step-by-step explanation:
When you solve problems like these you convert the percentages into fractions and multiply them together.
18%= 18/100 reduced------> 9/50
6% = 6/100 reduced------> 3/50
3/50 * 9/50 = 108/10000 reduced -------> 54/5000 reduced---->
27/2500. The probability is 27/2500, or 1.08%
Answer: the fraction for number 2 is 5/16, the decimal is 0.3125 this number as a percent is 31.25%
Step-by-step explanation: you're supposed to add all the numbers and the number you're being asked to find the probability of /the 5 nickels they were talking about, you divide 5/16 get 0.3125, then move the decimal over 2 spaces leaving you with 31.25% so number 2 is (fraction: 5/16, Decimal: 0.3125, percent: 31.25
now if you add one dime 1 quarter and 2 pennies then you have 19 total
so 5/19=0.263 then turn 0.263 into a percent it's 26.3 (slide the decimals over twice) so now you have ( fraction: 5/19, decimal: 0.263, fraction: 26.3)
... my head hurt
23/3 because 7 times which is 21 than add the 2 which was originally their and you get your answer 23/3
