Answer: C. Definition of an Altitude
Step-by-step explanation:
Given: In triangle MNO shown below, segment NP is an altitude from the right angle.
Let ∠MNP=x
Then ∠PNO=90°-x
Therefore in triangle MNO,
∠MPN=∠NPO =90° [by definition of Altitude]
[Definition of altitude : A line which passes through a vertex of a triangle, and joins the opposite side forming right angles. ]
Now using angle sum property in ΔMNP
∠MNP+∠MPN+∠PMN=180°
⇒x+90°+∠PMN=180°
⇒∠PMN=180°-90°-x
⇒∠PMN=90°-x
Now, in ΔMNO and ΔPNO
∠PMN=∠PNO=90°-x
and ∠MPN=∠NPO =90° [by definition of altitude]
Therefore by AA similarity postulate, we have
ΔMNO ≈ ΔPNO

Answer:
The answer to your question is the last option
Step-by-step explanation:
Quadratic equation
2 = - x + x² - 4
Order the equation from the highest power to the lowest power. Do not consider 2 because it is not consider in the options given.
x² - x - 4 = 0
Identify a, b and c
(1) x² -(1) x - 4 = 0
a = 1 b = -1 c = - 6
Substitution

Answer:
182 seconds
Step-by-step explanation:
Given:
Time taken for first lap is 50 seconds and each subsequent lap takes 20% longer than previous
Solution:
Time taken for first lap = 50 sec
For second lap
Each subsequent lap takes 20% longer than previous
Previous lap time = 50 sec
second lap = 50 + 20% of 50
second lap 
second lap 
second lap 
For third lap
Each subsequent lap takes 20% longer than previous
Previous lap time = 60 sec
Third lap = 60 + 20% of 60




Time taken for 3 laps is equal to sum of all three laps time.


Therefore, it takes 182 seconds (3 min, 2 seconds) to run three laps
Answer : C. Caplet form is the most expensive.
Tablet form comes in 50 mg tablets and cost $75.00 for a bottle of 100 tablets.
50 mg of 100 tablets so 50 * 100 = 5000mg
5000mg cost = $75.00
So 1mg of tablet form cost =
= 0.015
Capsule form comes in 75 mg capsules and cost $63.75 for a bottle of 85 capsules
75 mg of 85 capsules, so 75 * 85 = 6375mg
6375mg cost = $63.75
So 1mg of Capsule form cost =
= $0.01
Caplet form comes in 100 mg caplets and cost $70.00 for 40 caplets
100 mg of 40 caplets , so 100 * 40 = 4000 mg
4000mg cost = $70.00
So 1mg of Caplet form cost =
= $0.0175
Caplet form is the most expensive.
