Answer:
miles [or, 9.2 miles]
Step-by-step explanation:
<u>Complete Question:</u>
Christine runs 10 miles in 75 minutes. At the same rate, how many miles would she ru
n in 69 minutes?
<u>Solution:</u>
We need to find the unit rate first and then find our answer. To get unit rate, we need to know the number of miles she runs in "1 minute". So, we will divide number of miles by number of minutes, that is given. Hence:
That means in 1 minute, Christine runs 2/15th of a mile.
Now, we want to know how many miles she will run in 69 minutes. We simply multiply unit rate (2/15) by the number of minutes (which is 69). Thus we have:
In decimal, doing division, that is 9.2 miles
Answer: 100
Step-by-step explanation:
Because 25x4= 100 sorry if it’s wrong
Answer: m = 3.3 mol·58.326 mol = 192 g
Step-by-step explanation: molar mass of substance is
M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.
Amount of substance n = m/M and mass m = n·M
To do this, we calculated all possible solutions to this problem:
what x what = 52
Note that "what" and "what" in the above problem could be the same number or different numbers.
Below is a list of all the different ways that what times what equals 52.
<span>1 times 52 equals 52
2 times 26 equals 52
4 times 13 equals 52
13 times 4 equals 52
26 times 2 equals 52
52 times 1 equals 52
