a straight path of points that continues without end in both directions with no endpoints is a line.
This can be expressed as five m squared plus two.
Answer:
7 sqrt(2)
Step-by-step explanation:
We can use trig functions
sin theta = opposite side/ hypotenuse
sin 45 = 7/x
Multiply each side by x
x sin 45 = 7
Divide each side by sin 45
x = 7 / sin 45
x = 7 (sqrt(2) /2)
x = 14 / sqrt(2)
We do not leave square roots in the denominator
x = 14 / sqrt(2) * sqrt(2)/ sqrt(2)
12 sqrt(2)/ 2
= 7 sqrt(2)
Answer: What percentage of time did she spend practicing ballet?
Since all the answer have the letter r in it, r would be the unknown number.
In math the "/" line represents division.
So 50 divided by an unknown number would become 50/r/
The answer is D.
