Answer:
(a)
(b)
Total number of weeks is 8
Step-by-step explanation:
(a)
we are given
Chung has $10.00 in his coin jar
so, initial amount =$10.00
He plans to put $6.0 more into the jar every week
Let's assume number of weeks =x
so,
total money in jar after x week = (initial money) +(number of weeks)*(money put in every week)
so, we get
Total money in jar after x week is
(b)
we are given
Chung has $58
so, we can set M=58
and then we can solve for x
Subtract both sides by 10
Divide both sides by 6
and we get
So,
Total number of weeks is 8
58 +62 + 66 + 70 =256
256 seconds = 4 mins 16 seconds
3x67=201 and that is the answer for this question
Answer:
581
Step-by-step explanation:
<u>Population of Grizzlys</u>
1970 >>> 270
2005 >>> 115% INCREASE
We need to find 115% of 270 and increase 270 by that amount. Firstly, converting percentage to decimal (division by 100):
115/100 = 1.15
So, that would be now:
1.15 * 270 = 310.5
Increasing, we get:
270 + 310.5 = 580.5
We round to 581
In 2005, the population was about 581
4*4= 16 + 16= 32 :) You could do 4 * 4 that equals 16 then add 16 to that to get over 28.
