Step-by-step explanation:

$800 × 5% = $40

for 1 year, I earn $40

100 ÷ 40 = 2 remainder 2

Therefore I would have to leave the money in for at least 3 years to earn $100

Answer: 2.5 years

Step-by-step explanation:

The formula to calculate the simple interest is given by :-

I=Prt, where P is the principal amount , r is the rate of interest ( in decimal) and t is time ( in years).                                              

Given : P= $800   ; r= 5% =0.05   and  I=$100

Then , we have

100=800\times0.05t\\\\\Rightarrow\ t=\dfrac{100}{800\times0.05}=2.5

Hence, you must leave the money in the account for 2.5 years to earn $100 in interest.

Use the scale drawing and the scale factor to enlarge a square that has a side length of 12 in. Scale factor= 3 in:2m.
podryga [215]

Given:

The side of square = 12 in.

Scale factor of enlargement = 3 in : 2 m

To find:

The proportion that is use to solve the side length, x, of the enlarged square.

Solution:

Let, the side of length of enlarged square = x m

In case of enlargement the corresponding sides are proportional.

\dfrac{3}{12}=\dfrac{2}{x}

3x=2\times 12

3x=24

Divide both sides by 3.

x=\dfrac{24}{3}

x=8

Therefore, the required proportion is \dfrac{3}{12}=\dfrac{2}{x} and the side length of the square after enlargement is 8 m.

Why is it impossible to list the set of rational numbers using the roster method?
dsp73
It is impossible to list the set of rational numbers using the roster method because the set of rational numbers is uncountable/inumerable.

There is no way to list all the members of the set of rational numbers.

Last year, Nicholas started babysitting to earn extra spending money. Over the summer, he tracked how much money he earned at ea
Ierofanga [76]

Answer:

25%

Step-by-step explanation:

The 5 values of the given box plot are;

The minimum value = 20

The first quartile, the 25th percentile point, Q₁ = 25

The median or second quartile, the 50th percentile point, Q₂ = 30

The third quartile, the 75th percentile point, Q₃ = 40

The maximum value = 55

The range = The maximum value - The minimum value

∴ The range = 55 - 20 = 35

We note that Nicholas earned $25 or less from the minimum value up to first quartile, Q₁, which is the 25th percentile point, where we have 25 percent of the data points

Therefore, the percent of the time Nicholas earned $25 or less is 25 percent of the time.

There are 27 pupils. There are twice as many boys than girls. how many boys and girls are there
Anna71 [15]
Let x  =  the numbers of girls

the numbers of boys  = 2x 
x + 2x = 27
3x = 27
x = 9
2x = 2 . 9 =18
girls  =  9  &  boys  = 18
