Answer:

14.2

Step-by-step explanation: 99/9=11

11^2 + 9^2 =c^2

121 + 81 = c^2

The square root of 202 = c^2

14.2126704=14.2

14.2 =c

Complete the point-slope equation of the line through ( 1, 10) and (5.2).
forsale [732]

Answer:

y = -2x + 12

Step-by-step explanation:

The point-slope equation for a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept(value of y when x = 0).

(1,10)

This means that when x = 1, y = 10. So

10 = m + b

(5,2)

This means that when x = 5, y = 2. So

2 = 5m + b

From the first equation, b = 10 - m. So

2 = 5m + 10 - m

2 = 4m + 10

4m = -8

m = -2

And

b = 10 - m = 10 - (-2) = 10 + 2 = 12

So

y = -2x + 12

Mia paints interior walls at a rate of 12\dfrac{\text{m}^2}{\text{h}}12 h m 2 ​ 12, start fraction, m, start superscript, 2, end
Travka [436]

Answer:

2,000\ \frac{cm^{2}}{min}

Step-by-step explanation:

<u><em>The correct question is</em></u>

Mia paints interior walls at a rate of 12 m^2/h. At what rate does she paint in cm^2/min?

Remember that

1\ m=100\ cm

1\ h=60\ min

Convert m^2/h to cm^2/min

substitute the values

12\ \frac{m^{2}}{h}=12\frac{(100)^{2}}{60}=2,000\ \frac{cm^{2}}{min}
