Answer:
It will take 1 day.
Each women will make 17 blankets
Step-by-step explanation:
We can model the number of blankets of Susan and Ella as linear equations:
Susan: B = 8 + 9*t
Where B is the number of blankets and t is the time in days.
For Ella, we have:
B = 10 + 7*t
To find when they will have made the same number of blankets, we just need to equate the value of B from one equation to the value of B from the other, and then we find the value of t:
8 + 9*t = 10 + 7*t
2*t = 2
t = 1 day
After 1 day they will have made the same number of blankets.
This number of blankets is:
B = 8 + 9*1 = 8 + 9 = 17 blankets
In f(x) = 3x + 2, the x is being represented in the function. So, if we replace the x with the g(x) functions, we get:
f(g(x)) = 3(2x - 4) + 2
f(g(x)) = 6x - 12 + 2
f(g(x)) = 6x - 10
Answer:
E. 800%
Step-by-step explanation:
Since,
u = 8d/h² __________ eqn (1)
Now, density (d) is doubled and usage (h) is halved.
Hence the new life (u'), becomes:
u' = 8(2d)/(0.5h)²
u' = 8(8d/h²)
using eqn (1), we get:
u' = 8u
In percentage,
u' = 800% of u
In words, the percentage increase in useful life of the equipment is <u>800%</u>.
We will use d for drama and y for yearbook.
d + y = 64
d = y + 10
Now that we have the system if equations we can use substitution where you plug y+10 in for d in the first equation.
(y + 10) + y = 64
2y + 10 = 64
2y = 54
y = 27
If 27 of the 64 are in the yearbook club, 37 are in drama.
