Answer:
x = 10
, y = 10
Step-by-step explanation:
using the sine and cosine ratios in the right triangle and the exact values
cos60° =
, sin60° =
, then
cos60° =
=
=
( cross- multiply )
2x = 20
( divide both sides by 2 )
x = 10
and
sin60° =
=
=
( cross- multiply )
2y = 20
×
= 20
( divide both sides by 2 )
y = 10

What the two or more numbers or amounts? Something needs to be compared
Answer:
4 stacks of packages
4 * 4 = 16 pieces of pancake
Step-by-step explanation:
Maximum amount to spend ≤ $30
Milk chocolate = $3.25
Pancakes per stack = 5.50 (sold in stacks of 4)
Let number of stacks = s
In equality terms :
3.25 + 5.50s ≤ 30
5.50s ≤ 30 - 3.25
5.50s ≤ 26.75
s ≤ 26.75 / 5.50
s ≤ 4.86
Hence, 4 stacks of pancakes can be purchased
