Answer:

i think its 4/9

Step-by-step explanation:

use the method KCF

-keep the first fraction same

-reverse the sign e.g mutiplyings opposite is dividing

- change over the fraction so if 1/2 is original then flip it over and make it 2/1 so basically top heavy fraction

working out should look like this:

4 2

_ × _

9 9

now multiply as normal

Answer:

2/9 divided by 1/2 is equal to 2/9 times the reciprocal of 1/2, which is equal to 2.

So, 2/9 divided by 1/2 is equal to 2/9 times 2.

2/9 (2) = 4/9

Let me know if this helps!

Answer:

$1000 ; 500 ; 1000 ; y = 500x + 1000

Step-by-step explanation:

From the graph, the initial deposit which started the savings account is $1000 ; this is the value on the y - intercept, the value in the account at time or period = 0.

The slope :

x1 = 0 ; y1 = 1000

x2 = 6 ; y2 = 4000

Slope = Rise / Run

Rise = y2 - y1 = 4000 - 1000 = 3000

Run = x2 - x1 = 6 - 0 = 6

Hence,

Slope = 3000 / 6

Slope = 500

y - intercept = 1000 (from. Graph)

Equation in slope intercept form:

General form : y = mx + c

m = slope ; c = intercept

Equation is written as ;

y = 500x + 1000

A principal of $950 is invested in an account at 7 percent simple interest per year. What is the amount of the principal after 5
Nataly_w [17]
\bf ~~~~~~ \textit{Simple Interest Earned Amount}
\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$950\\
r=rate\to 7\%\to \frac{7}{100}\to &0.07\\
t=years\to &5
\end{cases}
\\\\\\
A=950(1+0.07\cdot 5)\implies A=950(1.35)\implies A=1282.5
