How long will it take 5000 to double in an account that pays 5.6% simple interest
Ganezh [65]
So... doubling 5000 is just 10,000, thus

\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &\$10,000\\
P=\textit{original amount deposited}\to& \$5,000\\
r=rate\to 5.6\%\to \frac{5.6}{100}\to &0.056\\
t=years
\end{cases}
\\\\\\
10000=5000(1+0.056t)\implies \cfrac{10000}{5000}=1+0.056t
\\\\\\
2=1+0.056t\implies 1=0.056t\implies \cfrac{1}{0.056}=t

Reptile [31]

Answer:

1/6

Question: Scott made a casserole for dinner he gave equal portions of 1/2 the casserole to 3 friends what diagram could scott use to find the fraction of the whole casserole that each friend got?

Step-by-step explanation:

Find attached the diagram Scott used to find the portion each friend got.

The shaded part indicate the portion of the casserole.

When Scott prepared the dinner = 1 portion of casserole

He shared 1/2 the portion to 3 of his friends:

Divide the diagram of the full portion into 2 to get ½ of the casserole

1/2 of the casserole = ½ × 1 portion = ½ portion

Each of his 3 friends would have equal portions = ⅓ of the ½ portion

The diagram of the ½ portion would be divided into 3 equal part

In terms of calculation = ½ × ⅓

= 1/6

Each of his friends would have 1/6 portion of the casserole.

If 1.7 plus 1.9 times a number equals the sum of the number and 74.7, what is the number? Express your answer as a simplified fr
xz_007 [3.2K]

Answer:

81.11 in decimal

81 1/9 in fraction

Step-by-step explanation:

Let the number be x

1.9 time a number is equal to 1.9x

1.7 plus 1.9 times a number is equal to 1.7 + 1.9x

Now given that

1.7 plus 1.9 times a number equals the sum of the number and 74.7

mathematically we have relation equation as

1.7 + 1.9x = x + 74.7

subtracting 1.7 from both side

1.7 + 1.9x  - 1.7 = x + 74.7 - 1.7

=> 1.9x = x + 73

subtracting x from both side

1.9x - x = x + 73 - x

0.9x = 73

dividing both side by 0.9

0.9x/0.9 = 73/0.9

x = 81.11 or 81 1/9

Thus, the number is

81.11 in decimal

81 1/9 in fraction
