Answer:
1/16
Step-by-step explanation:
We know that a^b / a^c = a^(b-c)
4^6/4^8
4^(6-8)
4^-2
We know that a^-b = 1/a^b
1/4^2
1/16
It gives you a few values. The values of f(t) and g(t) when time t=3, and
the values of the rates of change (first derivative) for both at the same time t=3.
f(3) = 8 unit
f ' (3) = 2 unit/s
g(3) = 3 unit
g ' (3) = 8 unit/s
--and also a value of the ratio of the two functions at t=3
Answer:
She will have 12 sections per fabric and 36 sections in all
Step-by-step explanation:
Betty buy 3 fabrics of 30 ft²
If she cut each to 2/5 of 1 ft²
The she will have
30 × 2/5
= 6 × 2
= 12
She will have 12 for each fabric and for the 3 fabrics, she will have
12 × 3 = 36
4 : 3 : 2
x - area unit
area of the kitchen = 4x
area of the playroom = 3x
area of the dinning room = 2x
The combined area of these three rooms is 189 ft².
Therefore we have the equation
4x + 3x + 2x = 189
9x = 189 |:9
x = 21 ft²
area of the kitchen = 4x = 4(21) = 84 ft²
area of the playroom = 3x = 3(21) = 63 ft²
area of the dinning room = 2x = 2(21) = 42 ft²
Answer:
35
Step-by-step explanation:
You can find it by multiplying the decimal of the fraction (In this case it's 0.7) by however many times it's happening (50).
0.7 x 50 = 35
