Answer:
His equation is correct but his calculations are incorrect.
Step-by-step explanation:
180-40=140 so y=140
Hope this helps!
Since x = y + 2
so
y + 2 + 4y = 7
5y + 2 = 7
5y = 7-2
5y = 5
y = 1
x= y + 2
x = (1) + 2
x = 3
(x,y) = (3,1)
20/8=2’5”
So the larger triangle is bigger by 2.5
So you times 5’6” by 2.5 to get your answer which is 14 ft
Hope this helps
Answer:
1600
growth
4%
Step-by-step explanation:
To solve this question, you must know what the equation really means.
P = population
t = time
1600 = initial population size
1.04 = is the percentage growth, (growth because it is greater than 1.)
So, the initial population size is 1600.
It is growth because the percentage is greater than 1.
(1.04 = 104%, 104%-100%=4%)
The population changes by 4%
