Answer:

4 $\frac{5}{16}$

Step-by-step explanation:

To solve, you can convert the mixed number into a fraction, so 8 $\frac{5}{8}$ = $\frac{69}{8}$ , then you will divide by 2, which would be the same as multiplying by $\frac{1}{2}$ because you would keep the first fraction, switch the sign and flip the second fraction.

So if you multiply $\frac{69}{8}$ by $\frac{1}{2}$ , you would get $\frac{69}{16}$ , which you could then simplify to

4 $\frac{5}{16}$ , which is your answer.

Marianne is completing a 4-mile route for

Bogdan [553]

Answer:

For 1 miles distance: 7/10 of a mile she runs and 3/10 she walks.

For 4 miles distance (4 times the previous distance) she will run:

4*(7/10) = 18/20 = 2.8 miles

and walk:

4*(3/10) = 12/10 = 1.2 miles.

The equation of three lines are given below

kotykmax [81]

Answer:

The line 2 and Line 3 are perpendicular to each others

But There is no relation between Line 1 and Line 2 , Line 1 and Line 3

Step-by-step explanation:

Given as :

The three line equation is

Line 1 : 2 y = 5 x + 6

Line 2 : y = $\frac{2}{5}$ x - 1

Line 3 : 10 x + 4 y = - 6

Now, The standard equation of line is

y = m x + c

where m is the slope of line

And c is the y intercept

So, From Line 1

2 y = 5 x + 6

or , y = $\frac{5}{2}$ x + $\frac{6}{2}$

I.e y = $\frac{5}{2}$ x + 3

So, slope of this line = $m_1$ = $\frac{5}{2}$

Again , From Line 2

y = $\frac{2}{5}$ x - 1

So, slope of this line = $m_2$ = $\frac{2}{5}$

Similarly , From Line 3

10 x + 4 y = - 6

I.e 4 y = - 6 - 10 x

or, y = - $\frac{6}{4}$ - $\frac{10}{4}$ x

I.e y = - $\frac{5}{2}$ x - $\frac{6}{4}$

So, Slope of this line = $m_3$ = - $\frac{5}{2}$

Now, If the lines are parallel , then the slope of the lines are equal

And If the lines are perpendicular , then the product of the slopes of the lines = - 1

Now, From given lines

$m_2$ × $m_3$ = $\frac{2}{5}$ × ( - $\frac{5}{2}$ )

I.e $m_2$ × $m_3$ = - 1

So, The line 2 and Line 3 are perpendicular to each others

But There is no relation between Line 1 and Line 2 , Line 1 and Line 3

Hence The line 2 and Line 3 are perpendicular to each others

But There is no relation between Line 1 and Line 2 , Line 1 and Line 3 Answer

June has a savings account with an annual simple interest rate of 2.6%. She hopes to gain $6,500 in interest over a period of el

leonid [27]

$\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\to &\$6500\\
P=\textit{original amount deposited}\\
r=rate\to 2.6\%\to \frac{2.6}{100}\to &0.026\\
t=years\to &3
\end{cases}$

she should have invested P, in order to get I = 6500

but she instead invested 17,801, how much more did she need? well, P - 17801

solve for P
