Perimeter is the beat word to describe equal shares of shapes
Answer:
Right angle triangle goes to 15m, 8m, 17m
Step-by-step explanation:
Square root of 15^2 + 8^2 is 17
(The use of a^2 + b^2 = c^2 - Pythagoras's Theorem)
So, 10m ,11m ,15m isn't a right angle triangle
Hope this helps!
Answer: 1/5 or 8 houses. Company X provides electricity to 8 houses, Company Y provides to 24 houses, so that would mean Company Z provides 8
Answer:
width equals 16
length = 20
Step-by-step explanation:
Hello there!
we know that the perimeter is 72 m
and the width is 4 m less then the length
perimeter is 2w+2l
w=width and l = length
72 + (2x-4) = 72+8 = 80
80 / 4 (because there are 4 values, w, w, l, l ) = 20
so now...
20 - 4 = w
16 = w
and 20 = l
16+16 = 32
20+20 = 40
32+40 = 72
Answer:
1. f(0) = 501170
2. decreasing
3. 2% decrease
4. 302438
Step-by-step explanation:
In 1995 x=0
f(x) = 501170(0.98)^0
f(0) = 501170
The population is decreasing since we are multiplying by .98 ^x
.98 is less than 1 so it is getting smaller each time.
1 -.98 = .02
It is decreasing by 2 % each year
2020-1995 =25 years
f(25) = 501170(0.98)^25
=302438.41862
Rounding to the nearest whole number
302438
