Answer:
10
Step-by-step explanation:
The IQR is the width of the box of the box plot. The box runs from 20 to 30, so its width is 10.
So firstly let’s set a ‘algebra’
Let’s make the hours working after school as ‘x’
So Chase works totally 18 hours last week
So the hours he works on Saturday is (18-x)
And given the salary of working after school is $8 per hour,and the salary of working on Saturday is $10,and he earned $156
So with these we can write a equation
8x+10(18-x)=156
solve it,
8x+180-10x=156
-2x=-24
X=12
as I said x is the hour working after school
The hour working on Saturday should be 18-x
18-12=6
Answer is 6
To have a remainder 3, we take away 3 from each number first.
<u>Take away 3:</u>
224 - 3 = 221
250 - 3 = 247
302 - 3 = 299
<u>Prime factorisation of each of the numbers:</u>
221 = <span>13 x 17
247 = 13 x 19
299 = 13 x 23
<u>Find HCF:</u>
HCF = 13
Answer: The largest number that can be divided is 13.</span>
