Answer:
1. D- All of the above
2. B- The material the acid is poured on
3. C- Mass of the ball
4. A- Temperature
Step-by-step explanation:
2. The control variable is what stays the same so the material the acid is poured on must be the same as different materials have different reactions to acids.
3. The independent variable is what's being changed and in this experiment the mass of the ball is changed each time
4. The independent variable is what's being changed and in this experiment the temperature is different in each cup.
Hope this helped! :)
To solve this problem you must apply the proccedure shown below:
1. You have to r<span>ewrite x=12 in polar form. Then, you have:
12=rCos</span><span>θ
2. Then, you must solve for r, as following:
r=12/Cos</span><span>θ
</span> 3. You have that 1/Cosθ=Sec<span>θ, therefore:
</span> r=12(1/Cos<span>θ)
</span> r=12Sec<span>θ
</span> Therefore, as you can see, the answer is: r=12Secθ<span>

Answer:
A certain television is advertised as a 50-inch TV (the diagonal length). If the width of the TV is 14 inches, how many inches tall is the TV?
Step-by-step explanation:
Answer:
60%
Step-by-step explanation:
51/85 = 0.6
0.6 * 100 = 60%
You would divide both sides by 6 so that the co efficient of the unknown number is equal to 1. Which makes 6m into 1m and 24 into 4. Which means m has to equal to 4
