Answer: y = 21x
Step-by-step explanation:
y in this expression represents the total amount of money, in dollars, the students raise from selling x flowerpots.
21 is the price of each flower pot.
x is the number of flower pots sold.
If for instance, they sold 30 flower pots, y(total amount in dollars) would be;
= 21x
= 21 * 30
= $630
The correct answer is D:
35 < 7 * 5 + 6
35 < 35 + 6
35 < 41
Correct!
Answer:
6
Step-by-step explanation:
Given information:
Interior angle of a polygon cannot be more that 180°.
One interior angle = 
Other interior angles are = 
Let n be the number of sides of the polygon.
Sum of interior angles is
Combine like terms.
.... (1)
If a polygon have n sides then the sum of interior angles is
.... (2)
Equating (1) and (2) we get
Isolate variable terms.
Divide both sides by 52.
Therefore the number of sides of the polygon is 6.
Answer:
m=45 degrees
n=15 degrees
Step-by-step explanation:
m=45 degrees because other 2 angles in it's triangle =90+45=135 degrees
180 degrees in any triangle so m=180-135=45 degrees.
m+n=60 degrees so n=60-45=15 degrees
Since sin²x+cos²x=1, we can plug (-12/13) for cos(x) to get (-12/13)²+sin²x=1
= 144/169+sin²x=1. Subtracting 144/169 from both sides, we get 25/169=sin²x. Square rooting both sides, we get 5/13 as sinx (since √25=5 and √169=13,as well as that it's in quadrant 2 - if it was in quadrant 3 or 4, it would be -5/13). Since cscx=1/sinx, we can plug (5/13) in for sinx to get 13/5 as our answer
