Answer:
The answer is 20
Step-by-step explanation:
Given that f(2)=1/5
And f(n+1)=f(n)*10
Let's start from n=2
f(2+1)=f(2)*10
f(3)=(1/5)*10
f(3)=2
Now let's take n=3
f(3+1)=f(3)*10
f(4)=2*10
f(4)=20
Answer:
157.5 square feet
Step-by-step explanation:
If an inch is 3 feet, then
3.5 inches = 10.5 feet (3.5*3)
5 inches = 15 feet (5*3)
The area of a rectangle is length times width so...
10.5*15 = 157.5
Answer:
the answer is 5.8
Step-by-step explanation:
divide numerator (8) by the denominator (10):
8 / 10 = 0.8
add this value to the integer part: 5 + 0.8 =
5.8 So,
5 8/10 = 5.8
Answer:
12.5cm
Step-by-step explanation:
Each side of the pentagonal garden has a length of 2.5 cm.
A pentagon has 5 sides.
Since the garden has congruent sides, all its lengths are equal.
Therefore:
Distance Walked by Tanya
= 5 X 2.5
=12.5cm
Tanya has walked 12.5cm in total.
