Answer:
I got -8m+24-32n
Step-by-step explanation:
8 and m equals 8m and since its negative 8 you add a negative sign: -8m
A negative and a negative equals a positive so its a positive sign and it equals +24:+24
A negative and a positive equals a negative so its minus 32n since the 4 includes an n:-32m
The student who said 302 is a greater number is correct because since it has a 0 it brings the number into the hundreds while 32 is a lesser value . another example would be to make 32 you would need 3 ten blocks and 2 ones blocks and to make 302 would need 3 hundreds blocks and 2 ones blocks
if 7/2 = x/81
then you cross multiply and get
2x = 567 then divide by 2 and you get
283.5 and that's your answer
Answer:
or ≈6.59
Step-by-step explanation:
We can first begin by simplifying each of the numbers with exponents. Recall that in a fraction exponent, the numerator is the power, while the denominator is the root.
Take 
for example. The '2' in the fraction means we must take the square of 25. √25 = 5.
The '3' in the fraction means we take the power, which means we must cube '5'.
5³ = 125. Therefore, = 125. Use this process for the other numbers:
The new fraction would look like:
Which simplifies to:
or ≈6.59
Answer:
0.573 m
Step-by-step explanation:
a. To find the depth, x, we first solve the differential equation to find the expression for I
dI/dx = (-1.21)I
dI = (-1.21)Idx
dI/I = -1.21dx
Integrating both sides, we have
∫dI/I = ∫-1.21dx
㏑I = -1.21x + C
I = exp(-1.21x + C)
I = exp(-1.21x)exp(C) Let exp(C) = A
I =Aexp(-1.21x)
when x = 0, I = L. Substituting these into the equation, we have
L = Aexp(-1.21 × 0)
L = Aexp(0)
L = A
So, I = Lexp(-1.21x)
we want to find x when I = L/2.
So, L/2 = Lexp(-1.21x)
1/2 = exp(-1.21x)
-1.21x= ㏑(1/2)
-1.21x= -㏑2
x = -㏑2/-1.21
x = 0.693/1.21
x = 0.573 m
