Answer:
50 muffins
Step-by-step explanation:
20 : 40%
y : 100%

y · 40 = 20 · 100
40y = 2000
40y ÷ 40 = 2000 ÷ 40
y = 50
Perimeter = add all the sides
Pool has 4 sides
So
22.3 + 22.3 = 44.6
75+75 = 150
150 + 44.6 = 194.6ft
Step-by-step explanation:
½ [cos(a − b) − cos(a + b)]
Using sum and difference formulas:
½ [cos a cos b + sin a sin b − (cos a cos b − sin a sin b)]
Distribute the negative:
½ (cos a cos b + sin a sin b − cos a cos b + sin a sin b)
Combine like terms:
½ (2 sin a sin b)
Simplify:
sin a sin b
Answer:
If two powers have the same base then we can multiply the powers. When we multiply two powers we add their exponents.
