List the next four multiples of the fraction 7/12

choli [55]

<h2>Hello!</h2>

The answer is:

$\frac{14}{12},\frac{21}{12},\frac{28}{12},\frac{35}{12}$

Let's explain with an example the definition of a multiple.

Multiple of the number 1 are: 1, 2, 3, 4, 5 and so...

Multiple of the number 3 are: 3, 6, 9, 12, 15 and so...

A multiple of a number is the repeated sum of itself, from the example:

Multiple of the number 1 are: Itself, (1+1), (1+1+1), (1+1+1+1), (1+1+1+1+1) and so...

Therefore,

Multiple of $\frac{7}{12}$ are:

$\frac{7}{12} =\frac{7}{12}(itself)=\frac{7}{12}*1 \\\\\frac{14}{12}= \frac{7}{12}+\frac{7}{12}=\frac{7}{12}*2\\\\\frac{21}{12}=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}=\frac{7}{12}*3\\\\\\\frac{28}{12}=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}=\frac{7}{12}*4\\\\\frac{35}{12}=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}=\frac{7}{12}*5$

Have a nice day!

qwelly [4]

Answer:

The solutions are t = 0 and t = 1. Since starting time is 0, the arrow is in the air for 1 second.

Step-by-step explanation:

Set the equation equal to zero.

−2t(8t − 8) = 0

Apply the Zero Product Property.

−2t = 0 or 8t − 8 = 0

Solve each equation for t.

t = 0 or 8t = 8

t = 1

1. A student invests $500 in a savings account that earns 4% interest per

bixtya [17]

Answer:

The equation can be used to determine the amount of money S(t) that her savings account has after t years is $S(t)=500(1.04)^t$

Step-by-step explanation:

A student invests $500 in a savings account

Principal = $500

Rate of interest = 4% = 0.04

We are supposed to find equation can be used to determine the amount of money S(t) that her savings account has after t years

Formula : $A=P(1+r)^t$

Where A is the amount after t years =S(t)

t = time

r = rate of interest in decimals =0.04

P = Principal=500

Substitute the value in the formula :

So, $S(t)=500(1+0.04)^t$

$S(t)=500(1.04)^t$

Hence The equation can be used to determine the amount of money S(t) that her savings account has after t years is $S(t)=500(1.04)^t$
