So, the scale is on the map is 3/10 inch equals to an actual 7/8 miles, then how many inches are there in 1 mile?

\bf \begin{array}{ccll}
inches&miles\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{3}{10}&\frac{7}{8}\\\\
x&1
\end{array}\implies \cfrac{\quad \frac{3}{10}\quad }{x}=\cfrac{\quad \frac{7}{8}\quad }{1}\implies \cfrac{\quad \frac{3}{10}\quad }{\frac{x}{1}}=\cfrac{\quad \frac{7}{8}\quad }{\frac{1}{1}}

\bf \cfrac{3}{10}\cdot \cfrac{1}{x}=\cfrac{7}{8}\cdot \cfrac{1}{1}\implies \cfrac{3}{10x}=\cfrac{7}{8}\implies 24=70x\implies \cfrac{24}{70}=x\implies \stackrel{inches}{\cfrac{12}{35}=x}

Find the radius and the diameter to the nearest hundredth when C = 7π yd. Use 3.14 for π.
valentinak56 [21]

Answer:

Diameter = 7

Radius = 3.5

Step-by-step explanation:

Hi! Ace here.

So, the formula to find circumference is dπ or 2rπ

So to find the diameter, you do the circumference/π

To find the radius, you'd do the circumference/2π

Plug-in those numbers and there you go!

Hope this helps, let me know if you have any questions.

I know this was a very vague explanation so I encourage you to ask any questions. Thank you!

Write an equation in slope-intercept form for the line that passes through (1,9) and (3,5).
kozerog [31]

Answer:

The answer to your question is    y = -2x + 11

Step-by-step explanation:

A (1, 9)

B (3, 5)

- Find the slope

 m = \frac{y2 - y1}{x2 - x1}

 m = \frac{5 - 9}{3 - 1}

 m = \frac{-4}{2}

        m = - 2

- Find the line equation

        y - y1 = m (x - x1)

        y - 5 = -2(x - 3)

        y - 5 = -2x + 6

        y = -2x + 6 + 5

        y = -2x + 11
