Answer:
80 + 4 + 2/10 or 0.2 + 2/100 or 0.02. When I wrote the fractions, it really depends on what your teacher taught you to do.
Step-by-step explanation:
8 x 10 + 4 x 1 + 2 x 1/10 + 2 x 1/00
That is just the explanation for the equation.
By applying the Pythagorean Theorem and the Trigonometry ratio, CAH, the value of cos(M) = 4/5
<em><u>Recall:</u></em>
Trigonometry ratios, <em>SOH CAH TOA</em> can be applied to solve a right triangle.
- Pythagorean Theorem can also be applied which is: c² = b² + a², where c is the longest side (hypotenuse length).
<em><u>Given:</u></em>
ΔMNL is a right triangle
ML = 25
NL = 15
Find MN using the Pythagorean Theorem:
MN = √(ML² - NL²)
MN = √(25² - 15²)
MN = 20
To find the value of cos(M), apply the trigonometry ratio, CAH, which is:
cos ∅ = Adj/Hyp
∅ = M (reference angle)
Hypotenuse = ML = 25
Adjacent = MN = 20
cos(M) = 20/25
cos(M) = 4/5

Answer:
A
Step-by-step explanation:
a = 3n-30 solve for 'n'
a + 30 = 3n
n = (a+30)/3
n(a) = (a+30)/3
Answer: The answer that is false is “Initially, Cassie has $20 dollars in her account.”
Step-by-step explanation: The reason why this is false is because the first statement that the slope of the line is -20 is true. The formula for slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Next the initial value is 275 because in these problems the y-intercept is technically the starting value in these problems. So since the initial value is 275 the last statement is false.
Have a nice day!

Are you acually in middle school because this is algebra 2 and im learning this now in High school
