Multiply the price by the percentage:

3.25 x 142% = 3.25 x 1.42 = 4.62

You pay $4.62

Two equations are given below:

Evgesh-ka [11]

The solution to the set of equations is (0,2).

Reasoning:

m + 4n = 8 -> 0 + 4(2) = 8

m = n - 2 -> 0 = 2 - 2

The isotope known as carbon-14 is radioactive and will decay into the stable form nitrogen-14. As long as an organism is alive,

yan [13]

Answer:

The number of half lives in 14000 years is 2.4258.

Step-by-step explanation:

Initial amount of carbon-14 = $N_o$

Final amount of carbon-14= N

Half life of carbon-14 = $t_{1/2}=5770 year$

Decay constant = k = $\frac{0.693}{t_{1/2}}=\frac{0.693}{5770 year}$

Age of the sample = t = 14,000 years

$N=N_o\times e^{-kt}$

$N=N_o\times e^{-\frac{0.693}{5770 year}\times 14,000 yeras}$

$N=N_o\times 0.1861$

Formula used for number of half lives

$N=\frac{N_o}{2^n}$

where,

N= amount of reactant left after n-half lives

$N_o$ = Initial amount of the reactant

n = number of half lives

$N_o\times 0.1861=\frac{N_o}{2^n}$

$2^n=\frac{1}{0.1861}$

$2^n=5.3734$

Taking log both sides

$n\log 2=\log (5.3734)$

n = 2.4258

The number of half lives in 14000 years is 2.4258.

49w^2-4=0. Simplied fraction?

HACTEHA [7]

Answer:

{-2/7, 2/7}

Step-by-step explanation:

Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.

49w^2-4=0 is the product of the sum and difference of two squares:

(7w - 2)(7w + 2) = 0

Setting each factor equal to zero and solving for w, we get:

{-2/7, 2/7} as the solutions.

Type the missing number in this sequence: 1, , 36, 216, 1,296

Simora [160]

It’s 6, because each number is multiplied by 6 in the sequence. For instance, 1 times 6 is 6. 6 times 6 is 36. 36 times 6 is 216, and so on and so forth.
