Let x represent the number of weeks, then w<span>ithdrawing $10 every week from a perfect balance of $400</span> can be represented as an expression as follows:
400 - 10x
Answer:
The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
Not positively sure but I believe it goes like this
Answer: 9x+26+5x=180
14x+26=180
180-26=14x
14x=154
X=15
We know that
Right triangles PBM and MTF are similar
because
angle PMB=angle TMF
and
angle BPM=angle FTM
and
angle B =angle F=90 degrees
so
corresponding sides are
BM and MF
PB and TF
PM and MT
(PB/TF)=BM/MF
solve for PB
PB=(TF*BM)/MF
where
TF=6ft
BM=20 ft
MF=3 ft
so
PB=(6*20)/3------> 40 ft
the answer is
<span>the height of the peak is 40 ft</span>
