Problem 1. Three students and one adult went to the baseball game on a Saturday, how much was their total bill?
problem 2. Five students and five adults went to the baseball game on a Monday, how much was their total bill?
problem 3: One student and two adults went to the baseball game on a Friday, how much was their total bill?
answer: their total bill was $55
explanation: two adults ($20 + $20 = $40) + one student ($40 + $15 = $55) the discount does not apply because they did not attend the baseball game on a Saturday
Answer:
+120/169 or -120/169
Step-by-step explanation:
- let
where, alpha is some angle that satisfies the assumed condition.
- so,
[ taking cos to the other side or applying cos on both sides]
- now, substitute this in the given expression
as sin =
[by general trigonometry formula: ]
so if , we can get sin from the above formula as + or - 12/13
(because, after taking square root on both sides we keep + or -]
- as, sin
[by general trigonometry formula]
- here, now
so, the final value can be 120/169 or -120/169.
Answer:
y-3=7/6(x-4)
Step-by-step explanation:
the equation for point-slope form is y-y1=m(x-x1)
first let's find the slope (m)
the formula for slope is (y2-y1)/(x2-x1)
the given points: (4,3) and (-2,-4)
label the points:
x1=4
y1=3
x2=-2
y2=-4
now substitute into the equation
m=(-4-3)/(-2-4)
m=-7/-6
m=7/6
the slope is 7/6
now substitute the numbers into the equation for point-slope form
y-3=7/6(x-4)
Hope this helps :)!
