a. 20 because y is the amount of $$ in account now
b. 12 a $$
c. 260, bc 12*20= 240 240+20=260
General equation of Ellipse centered at (h,k) is given as
where a is the radius along x-axis
and b is radius along y-axis.
Given : The equation of elliptical path of Earth as
Comparing the equation with the general equation, we get
(h,k) as (-2.5,0)
a = 
b = 
We have the Sun located at the coordinate (0,0).
Hence, the distance between Sun and Earth in July = 149.5 + 2.5 =152
∴ Earth's distance from the Sun in July is 152 million kilometers.
Answer: C
Step-by-step explanation: The numerator is the angle measure, and the denominator is the side length. For angle B, the angle is 47 degrees. The opposite side is b, which is 85. We are finding the angle A, which is the numerator. The side 94 is opposite of angle A.
Answer:
9/10
30%
Step-by-step explanation:
Only in trial number 4, there is just one correct answer. In all other 9 trials at least 2 answers were correct. So the probability is 9 out of 10 trials give a winning outcome, in short, 9/10.
Giving birth to three males first, is true in 3 out of 10 trials. You can count the total numbers of Y's in the last column.
So 3/10 which is 0.3 which is the same as 30%.
