Tara's Bedroom: A = lw
A = (9)(8)
A = 72 ft²
Jody's Bedroom: A = lw
A = (7)(10)
A = 70 ft²
Tara's bedroom has the greater area than Jody's bedroom.
Answer:
x = 8*root3
y = 16
Step-by-step explanation:
You can use tangent and cosine of 60° to find x and y, BUT THERE'S A SHORTCUT. You pointed out that its a 30°-60°-90° triangle. That is a special right triangle. Here's the shortcut:
the longest side (hypotenuse) is double the shortest side. We have an 8 on the shortest side, so the hypotenuse (longest side) is 16. This ALWAYS works for 30°-60°-90° triangles!
Another shortcut:
The longer leg is the shorter leg × root3.
This ALWAYS works on 30°-60°-90° triangles.
So on your triangle, the short side is 8, that means the longer leg is 8×root3.
ta-daaaa!

Step-by-step explanation:
Answer: The treatments in the study are strength training, flexibility training, aerobics, and jogging.
Step-by-step explanation:
A correct description of a feature of the study is that the treatments in the study are strength training, flexibility training, aerobics, and jogging.
It should be noted that the study has no replication. Also, the experimental units are the 40 members that participated.
Therefore, the correct option is D.
