a. The formula for the area of rectangle is:
A = l w
so given that A = 3/5 m^2 and w = 2/5 m,
l = A / w
l = (3/5 m^2) / (2/5 m)
l = 3/2 m or 1.5 m
b. We take the ratio l/w:
l/w = (3/2 m) / (2/5 m)
l/w = 3.75
So the length is 3.75 times greater than width
A worker is paid $0.10 on the first day, $0.30 on the second day, $0.90 on the third day, $2.70 on the fourth day, and so on.
Notice that the pattern of getting wages is 3 times of the previous day.
Like the wages for the first day= 0.10
Second day = 0.10*3 = 0.30
Third day = 0.30 *3 = 0.90 And so on.
Hence the wages represent a geometric sequence where
first term: a = 0.10 and common ratio: r = 3.
And we need to find the total does the worker earn after working 14 days:.
Formula to find the sum of nth term a geometric sequence is:
=
=
=
=
= 239148.4
So, he will earn $239148.40 fter 14 days.
Hope this helps you.
Answer:
(x+8)(x+7)
Step-by-step explanation:
Find two numbers that add to
b
and mulitply to
a*c
so find two numbers that add to
15
and mulitply to
56
Those two numbers are 8 and 7
therefore the answer is
(x+8)(x+7)
