Answer:
Number of students= 820.64 = 821
Step-by-step explanation:
Giving the following information:
Current attendance= 950 students
Number of periods= 3 years
Decrease rate= 5%
<u>To calculate the number of students in attendance in 3 years, we need to use the following formula:</u>
Number of students= current attendance*(1+decrease rate)^(-n)
Number of students= 950*(1.05^-3)
Number of students= 820.64 = 821
Answer:
$124,400
Step-by-step explanation:
The scholarship pays for 30% of her tuition. This leaves her responsible for 100-30 = 70% of it. 70% = 70/100 = 0.7; this makes her part of the yearly tuition
0.7(29500) = 20650
She is still responsible for her $9600 room and board per year. Her books are paid for by the scholarship; however she still has the lab and facility fees at $850 per year.
Altogether this gives her a total of
20650+9600+850 = 31100 per year. Over the course of 4 years, this will cost her
31100(4) = 124400
The lesser number is 30.
It took me about one minute to determine the two numbers by simple logic alone.
30 and 60 are the two numbers.
But, equation-wise, you have ...
30 x 2(30) = 1800
30 x 60 = 1800
Answer:
<NBE = 120°
Step-by-step explanation:
From the above attachment,
<KMB = 30°
<KBT = 90° (perpendicular angles are equal to 90°)
<MBE = x
<KMB + <KBT + <MBE = 180° (angles on a straight line are equal to 180°)
30° + 90° + <MBE = 180°
120° + <MBE = 180°
Solve for <MBE
<MBE = 180° - 120°
<MBE = 60°
<MBE = <TBN (vertical angles are congruent, making them equal to each other).
<TBN = 60°
<TBN + <NBE = 180° (angles on a straight line are equal to 180°)
60° + <NBE = 180°
<NBE = 180° - 60°
<NBE = 120°
Angle <NBE is equal to 120°
