Emily buys a toaster for 10%off if she pays 36 then what was the original price

PtichkaEL [24]

x-0.1x=36

where x is the original price
0.1x is the discount (10% of the original price)
36 is the price paid

x-0.1x=36
0.9x=36
----- ----
0.9 0.9
x=40

Consider a nuclear power plant that produces 1200 MW of power and has a conversion efficiency of 34 percent (that is, for each u

cestrela7 [59]

Answer:

The amount of nuclear fuel required is 1.24 kg.

Step-by-step explanation:

From the principle of mass energy equivalence we know that energy generated by mass 'm' in an nuclear plant is

$E=m\cdot c^2$

where

'c' is the speed of light in free space

Since the power plant operates at 1200 MW thus the total energy produced in 1 year equals

$E=1200\times 10^6\times 3600\times 24\times 365=3.8\times 10^{16}Joules$

Thus using the energy produced in the energy equivalence we get

$3.8\times 10^{16}=mass\times (3\times 10^{8})^2\\\\\therefore mass=\frac{3.8\times 10^{16}}{9\times 10^{16}}=0.422kg$

Now since the efficiency of conversion is 34% thus the fuel required equals

$mass_{required}=\frac{0.422}{0.34}=1.24kg$

What would be the probability that randomly

saveliy_v [14]

The chances would be (if you cant get duplicates)

1/6

1/5

1/4

If you want the states in order

You multiply them together

6 x 5 x 4 = 1/120 chance to get them in that order
