Estimate the answer by rounding each fraction to the nearest whole number and then adding.

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

First, we round the fractions.

If a fraction is half or more it rounds up, and if the fraction is less than half it rounds down.

7/10 is greater than half so it rounds up and we add 1 to 13 to get 14.

1/8 is less than half so we round down and remove the fraction so we are left with 10.

Then we add.

14+10=24

siniylev [52]

Answer:

A) 1/45

B) 1/60

Step-by-step explanation:

Part A

The actual car has a length to width ratio of ...

length/width = (570 cm)/(180 cm) = 57/18 = 3 1/6

The rectangle on the screen has a length to width ratio of ...

length/width = (13 cm)/(4 cm) = 3 1/4

Relative to its width, the screen rectangle is longer than necessary for a model of the car. So, the scale factor will be determined by the width of the car relative to the width of the screen model.

For a model width of 4 cm, the scale factor is ...

model/life-size = (4 cm)/(180 cm) = 1/45

Part B

For a model width of 3 cm, the scale factor is ...

model/life-size = (3 cm)/(180 cm) = 1/60

$\underline{\underline{\large\bf{Solution:-}}}\\$

The standard form of a line is given by -

$\green{ \underline { \boxed{ \sf{Ax+By=C}}}}$

where

A= integer
x = x-intercept
B= integer
y = y-intercept
C = constant

<h3>Given Equation: - </h3>

$\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} -1 \\\end{gathered}$

Arranging equation in standard form -

$\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{1}{1} \quad (1 = \frac{1}{1})\\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{1 \times 4}{1 \times 4} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{4}{4} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf y = \frac{-5x-4}{4} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 4y = -5x-4 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 4y +5x =-4 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 5x +4y=-4 \\\end{gathered}$

Comparing with standard form of line -

A = 5
B = 4

Thus , 5 is our required answer.
