Answer:
The difference in the medians of both weeks is 5 minutes.
Answer:
a = 4,
b = 12
c = 10
d = 15
Step-by-step explanation:
Since the product of each column is equal, therefore,
b*5 = 60
b = 60 ÷ 5 = 12
c*6 = 60
c = 60 ÷ 6 = 10
Since the sum of each column are equal, therefore,
12 + 10 + a = 5 + 6 + d
22 + a = 11 + d
Think of a number you can add to 22, and another number you can add to 11, which will make both sides equal. Add both numbers, whenmultiplied together should give you 60.
Factors of 60 are:
(a, d)
(1, 60) => 22 + a = 11 + d => 22+1 = 11+60 (incorrect)
(2, 30) => 22 + a = 11 + d => 22+2 = 11+30 (incorrect)
(3, 20) => 22 + a = 11 + d => 22+3 = 21+20 (incorrect)
(4, 15) => 22 + a = 11 + d => 22+4 = 11+15 => 26 = 26 [CORRECT]
(5, 12) => 22 + a = 11 + d => 22+5 = 11+12 (incorrect)
(6, 10) => 22 + a = 11 + d => 22+6 = 11+10 (incorrect)
Therefore,
a = 4,
d = 15
Answer:
a. 4/7
e. 3/4
Step-by-step explanation:
For each part of the question, count the dots that meet the first requirement, and count the dots that meet the "fraction of ..." requirement. The desired fraction is the ratio of these numbers. In the answers above, we have reduced the fractions to lowest terms, but the question does not seem to require that.
__
a. The desired fraction is ...
(dots in the triangle)/(all dots) = 16/28 = 4/7
__
e. (dots in the rectangle not in the circle)/(dots in the rectangle) = 9/12 = 3/4
Answer: 2 times
Step-by-step explanation:
Hi, since 1000 milliliters = 1 liter
We have to convert the 2 liters into milliliters:
2 x 1000 = 2000 milliliters, so she is using a 2,000 milliliters pincher.
Now we have to multiply the number of friends (10) by the amount of lemonade she serves to each one (400 ml)
400 x 10 = 4,000 milliliters
Finally, we have to divide the amount of lemonade she needs to serve (4,000 ml) by the capacity of the pitcher (2,000), to obtain the number of times that she will need to fill the pitcher.
4,000/2,000=2 times
