16a.) π
16b.) 
= 7 ÷ 15
Put (7 ÷ 15) in your calculater to get 0.4666667
That multiplied by 100 and rounded to the nearest whole percent is
47%
17a.) 24 + 16 + 14 = 54
17b.) 8 ÷ 27 = 0.296
0.296 × 100 = 29.6
Rounded to the nearest whole number is 27%
Factor: Trying to factor by splitting the middle term
The first term is 15a^2, its' coefficient is 15
The middle term is - 58a, its' coefficient is - 58a
The last term is "The Constant" is +48
Multiply the coefficient of the first term by the constant 15(48) = 720
Find two factors of 720, whose sum equals the coefficient of the middle term, which is -58

Factoring: 15a^2 - 58a + 48 = 0
Factor left side of equation:
(5a - 6)(3a - 8)
Set fractions equal to Zero
5a - 6 = 0 or 3a - 8 = 0
Answer : a = 6/5 = 1.200
or a = 8/3 = 2.667
Hope that helps!!!!
Answer:
B: 5/13
Step-by-step explanation:
pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5
sin = opp/hyp
sin 5/13
