Perimeter = 10.28
Area = 7.14
Since it decreases by 36 each year, the change would be 36+36+36+36=36*4=144
For a, we can plug in values for t, so 2000-(200*1)=1800 for the first year,
2000-(200*2)=1600 - do you see the pattern here? It subtracts by 200 every year, so 1600-200=1400 for the third year and 1400-200=1200 for the fourth year.
First: let’s get Ben’s current age:
16+4=20
Next let’s get Dunn’s current age:
4/7=20/x
Cross multiply and divide:
x=35
Let’s now add 10 to both ages:
Ben 20+10=30
Dunn 35+10=45
Lastly, let’s find the lowest common multiple of 30 and 45 to determine the ratio:
30:45
Both 30 and 45 can be divided by 15.
30/15=2
45/15=3
Answer:
2:3
Answer:
LN = 17
Step-by-step explanation:
an estimate of what the line looks like:
L ———————M—————————— N
LN = LM + MN
= 7 + 10
= 17
Answer:
9:13.
Step-by-step explanation:
$1.30 = 130 cents
So the ratio is 90:130
= 9:13.
