16x²y² - 12xyz -12xyz + 9z²
16x²y² - 24xyz + 9z², a perfect square trinomial.
Using the side length as the hypotenuse of a right triangle and half the given angle as the adjacent angle. Find the length of the base of a right triangle. This would be half the length of BD.
Cos(60) = adjacent leg/ 10
adjacent leg = cos(60) x 10
Adjacent leg = 5
Length of BD = 5x 2 =
10
Answer:
x = 11
Step-by-step explanation:
69° + (2x - 1)° = 90° (complementary angles)
69 + 2x + 1 = 90
Add like terms
69 - 1 + 2x = 90
68 + 2x = 90
Subtract 68 from each side
68 + 2x - 68 = 90 - 68
2x = 22
Divide both sides by 2
2x/2 = 22/2
x = 11
Answer:
300%
Step-by-step explanation:
Let p be the percent, of means multiply and is means equals
p*24 = 72
Divide each side by 24
24p/24 = 72/24
p =3
Multiply by 100 to change from decimal form to percent form
3*100
300%

Answer:
1.345
Step-by-step explanation:
I think the question you are trying to ask is (15/100) + (1/50) + (1.175) =
Convert all the fractions which includes 15/100 and 1/50 to decimals
Thus we have 15/100 = 0.15 and 1/50 = 0.02
The question is: 0.15 + 0.02 + 1.175 = 1.345
