Explanation:
We are trying to determine the value of
h
in the compound growth formula
XXX
20
×
(
1
+
0.85
)
h
=
2000
or, simplified:
XXX
1.85
h
=
100
Taking the
log
1.85
of both sides:
XXX
log
1.85
100
With the aid of my trusty spreadsheet:
XXX
h
≈
7.48582192
The sunflower is 2.387 meters tall.
The question is asking: which rounding will result in the greatest value?
To see, we need to round 2.387 to meter, tenth meter, and hundredth meter.
Meter - 2 meters
Tenth meter - 2.4 meters
Hundredth meter - 2.39 meters
As you see, rounding to the tenth meter gives the greatest value of 2.4. Therefore, Bahir should use a decimal rounded to the tenth meter.
Let's call the width: w
the lenght is then 3w+4 ("4 more than 3 times the width")
and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.
this is also equal to 18.4:
8w+8=18.4
8w=10.4
w=1.3
this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9
and the area is their product:
1.3*7.9=10.27
Answer:
13
Step-by-step explanation:
1710/125 = 13.68
You need
125 x 13 = 1710
A student could take 13 credits.
