Tim installs 50 square feet of his floor in 45 minutes. At this rate how long does it take him to install 495 square feet.

Nina [5.8K]

50 sqft = 45 min
495 sqft = x min

495/50 is 9.9. So we know we multiplied 50 by 9.9 to change it to 495.
Do the same on the other side. 45 x 9.9 = 445.5.

It will take him 445.5 minutes, or 7.425 hours

Work out the length of ab, give your answer to 3 significant figures

Aleksandr [31]

Answer:

D = 9.85 units

Step-by-step explanation:

A (1,7) and B(10,3)

Using Distance Formula to find the length

=> Distance Formula = $\sqrt{(x2-x1)^2+(y2-y1)^2}$

=> D = $\sqrt{(10-1)^2+(3-7)^2}$

=> D = $\sqrt{(9)^2+(-4)^2}$

=> D = $\sqrt{81+16}$

=> D = $\sqrt{97}$

=> D = 9.85 units (Upto 3 sfs)

If f(x) is an even function and (6, 8) is one the points on the graph of f(x), which reason explains why (–6, 8) must also be a

Vikki [24]

If $f(x)$ is an even function, then $f(x)=f(-x)$ . In this case, $f(6)=8=f(-6)$ .

This is because an even function is symmetric about the $y-axis$ . Hence the outputs of a negative x-value and a positive x-value are the same.

The correct option is the first option.

Since the graph is even, the outputs of a negative x-value and a positive x-value are the same.
