\tt Step-by-step~explanation:

We have to find out what the shaded regions represent. We can count up ten rectangles in total, and three of them are shaded. We take the amount of shaded rectangles over the total amount to get \tt \frac{3}{10} as a fraction, and 0.3 as a decimal.

\tt First~option:

The first choice is 0.300. The zeroes at the end of the number do not mean anything, so we can simplify it to 0.3. 0.3 is equal to 0.3, so this is not the answer.

\tt Second~ option:

The second choice is 0.30. Again, we can simplify it to 0.3. We can see that it is equivalent to 0.3, so this is not the answer, either.

\tt Third~option:

Our third choice is 0.3. 0.3 = 0.3, so this is not our answer either.

\tt Fourth ~option:

Our final choice is 0.030. Take out the last zero to get 0.03. 0.03 is equal to \tt \frac{3}{100}, so this is our answer, since it is not 0.3.

\large\boxed{\tt Our ~final~answer:~Last~option:~0.030}

A country's population in 1995 was 184 million. in 2002 it was 188 million. estimate the population in 2006 using exponential gr
GrogVix [38]
P = A.e^(r.t) is the population growth formula, where A is the initial population in a given year, exponent "r" =growth rate and exponent t = time

A₍₁₉₉₅₎ = 184 Mil. after t = 7 years, P₍₂₀₀₂₎ = 188 Mil

Let's calculate te growth rate:

P₍₂₀₀₂₎ = A₍₁₉₉₅₎.e^rt

188 = 184.e(^7r)

188/184 = e^(7r)

ln(188/184) = 7.r.lne
 0.0215 = 7.r   and r = 0.0030 = 0.3%

Population in 2006

P₍₂₀₀₆₎ = P₍₂₀₀₂₎.e⁽⁰.⁰⁰³ˣ⁴

P₍₂₀₀₆₎ = 188.e⁰.⁰¹² = 190.2 Mil

Mr. Smith donated $378 to 2 charities. Charity A received 5 times as much as Charity B. How much did Charity B received from Mr
MariettaO [177]

Answer:

$63

Step-by-step explanation:

let x represent Charity B then Charity A = 5x

Sum the two and equate to 378, that is

x + 5x = 378

6x = 378 ( divide both sides by 6 )

x = 63

Thus Charity B received $63

Show 46/200 on the hundredths grid. then write the fractions as a demical
SSSSS [86.1K]
If we want to has 100 in the denominator we have to divide numerator and denominator by 2. Then total value of fraction doesnt change.
\frac{46}{200}= \frac{46:2}{200:2}= \frac{23}{100}
Now read the fraction, its 23 hundreds, now just write as decimal, so, 0.23
