8m + 2q = 18.00
3m + q =. 7.50
8m + 2q = 18.00
-6m - 2q = -15.00
2m = 3.00
m = $1.50 each muffin
3(1.50) + q = 7.50
4.50 + q = 7.50
q= $3.00 for each quarter of milk
Answer:
first you add then you subtract
Step-by-step explanation:
<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>
