Sin 23° = Opposite/Hypotenuse = b / c
0.39 = b / 30
b = 0.39 · 30
b = 11.722 cm
Area of a triangle:
A = 1/2 b h
A = 1/2 · 11.722 · 27.6
A  ≈ 161.7 cm²

The table shows the relationship "Mason rode 15 miles per hour on his bicycle."
Tems11 [23]

The statements which are correct are-

  • The number of miles increases as time increases.
  • The number of hours causes a change in the number of miles ridden.
  • The variable h is the independent variable.

Step-by-step explanation

The above table displays the relationship between the time taken in hours ("h") by Mayon to cover the distance (miles "m").

It means that the distance is dependent on time in hours. Hence, the variable "m" is a dependent variable since it depends on time "h" for which bicycle is being ridden.

Similarly, the variable "h" is an independent variable.

As seen from the table, the value of "m" continuously increases for the value of "h" and thus the number of hours causes a change in the distance ridden.

Slav-nsk [51]
Hey hey!


56 would be the answer.

WAIT, don’t leave just yet! You have to show at least some work! You CANT learn if you don’t know what you’re doing.

Here’s how I got the answer:

7:4 walls = 10:8 people =M:40 minutes
M = (7/4) / (10/8) x 40
M = 56 minutes.

If that helped let me know by hitting the thanks button or reply with any help you need.

Have a FABULOUS DAYYY!
