Answer:
19.99 + 0.99x ; 21.97
Step-by-step explanation:
19.99 + 0.99x
19.99 + 0.99(2)
19.99 + 1.98
21.97
So,
There are 7 cherry gumballs and 6 grape gumballs.
The total gumballs is 13.
Therefore, the ratio of grape gumballs to total gumballs is 6:13.
Answer:
30
Step-by-step explanation:
15 - 20
13 - 10
20+10=30
We are given that x is the arclength from P(1,0) to T(3/4,4/5). In the case of a unit circle, the arclength from P(1,0) to a point T on a unit circle is equal to the radian angle that we rotate from the positive x axis up to T(3/4,4/5). So x is some radian angle. We don't actually have to solve for x, but you can find it using arctan (.8/.75) = 0.8176 radians or about 46°
Then we are told to add π to this x. If you add a rotation of π to a point on a circle, you are rotating that point by 180°. A 180° rotation about the origin is the same as a reflection about the origin. Recall that the transformation for a 180° rotation is (x,y) -> (-x, -y).
Therefore it should be T ' (-3/5, -4/5).
