First just make the whole number a fraction.
3 in fraction form is 3/1.
Now make it have a common denominator with the fraction 1/2.
Just multiply both the numerator and denominator by 2.
This gives you 6/2
Now add!
6/2 + 1/2 = 7/2
So 3(1/2) = 7/2.

<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.
cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41
Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.
(A) 0.10 feet
(B) 0.05 feet</span>
Answer:
I'd say about 50/50 cuz say there is 6 red cards and 7 black cards then it depends on the luck of the draw
