Answer:
P=20%
Step-by-step explanation:
Let's suppose that each question in the test has one and only one correct answer. This means we have 1 desired outcome out of the total 5 desired outcomes. Therefore:
Probability=#of desired outcomes / #of possible outcomes
or
P=0.20
P=20%
The answer is 161.70 N.
EXPLANATION
To change from mass to weight multiply by gravity (9.8 m/s^2)
Fw = m * 9.8 m/s^2
Fw = 16.5 kg * 9.8 m/s^2 = 161.70 N.
Triangle area formula: base*height/2
so, 14*10/2 = 7*10 = 70 sq. in.
Answer:
D) 2x² + 4x - 30
Step-by-step explanation:
Follow the FOIL method:
FOIL =
First
Outside
Inside
Last
...and is the order you multiply to solve:
(x + 5)(2x - 6) =
(x)(2x) = 2x²
(x)(-6) = -6x
(5)(2x) = 10x
(5)(-6) = -30
Combine like terms. Simplify:
2x² -6x + 10x - 30 = 2x² (-6x + 10x) - 30 = 2x² + 4x - 30
2x² + 4x - 30 is your answer.
