Mark is buying supplies for his students. He is buying a notebook (n) and a pack of pencils for each of his 25 students. Each pack of pencils costs $1.25.
If Mark's total cost is $156.25, which of the following equations can be used to find how much each notebook cost? Select TWO that apply.
A - 25(n) +31.25 =165.25
B - 1.25(n)+25=156.25
C- 25(n)=156.25+31.25
D - 25(n)=156.25−31.25
Answers
$5
Step-by-step explanation:
Note. There are no options to select.
Let the notebook cost x, then Mark spent:
25x + 25*1.25 = 156.25
25x + 31.25 = 156.25
25x = 156.25 - 31.25
25x = 125
x= 125/25
x= 5

A plane goes from a standstill to 350 mi/hr in about 45 sec. What is the plane's acceleration?
Answers
Answer:
The acceleration is 466.7m/s^2
Step-by-step explanation:
Given
[tex]u = 0m/s[/tex] -- Initial Velocity
It is 0 because the plane starts from a standstill
[tex]v = 350mi/h[/tex] -- final velocity
[tex]t = 45s[/tex] -- time
Required
Determine the acceleration
This is calculated using Newton's first equation of motion
[tex]v = u + at[/tex]
Convert time to hour
[tex]t = 45s[/tex]
[tex]t = \frac{45}{60}hr[/tex]
[tex]t = 0.75hr[/tex]
Substitute values for v, u and t
[tex]350 = 0 + a*0.75[/tex]
[tex]350 = 0.75a[/tex]
Divide both sides by 0.75
[tex]\frac{350}{0.75} = a[/tex]
[tex]466.67 = a[/tex]
[tex]a=466.67m/s^2[/tex]
Hence, the acceleration is 466.7m/s^2

Answer:
The value of the third side c = 12.52
Step-by-step explanation:
Step(i):-
Given thatΔABC is a right angle triangle
AB = a = 6
BC = a =11
Find AC = ?
Step(ii):-
By using Pythagorean theorem
AC² = AB²+BC²
⇒ c² = 6² +11²
⇒ c² = 36 +121
⇒ c² = √157
c = 12.52
The value of the third side c = 12.52

Answers
Answer:
(d) and (e) are true
Step-by-step explanation:
Given
[tex]Food = 23\ oz[/tex]
See attachment for proper presentation of question
Required
Select all true statements
For any option to be true, it must satisfy the following condition.
[tex]Days * Food = 23[/tex]
Option (a):
[tex]Days = 6[/tex]
[tex]Food = 4\frac{1}{6}[/tex] per day
So, we have:
[tex]Days * Food = 6 * 4\frac{1}{6}[/tex]
[tex]Days * Food = 6 * \frac{25}{6}[/tex]
[tex]Days * Food = 25[/tex]
This is not true because: [tex]25 \ne 23[/tex]
Option (b):
[tex]Days = 10[/tex]
[tex]Food = 2\frac{2}{23}[/tex] per day
So, we have:
[tex]Days * Food = 10 * 2\frac{2}{23}[/tex]
[tex]Days * Food = 10 * \frac{48}{23}[/tex]
[tex]Days * Food = \frac{480}{23}[/tex]
[tex]Days * Food = 21[/tex] --- approximated
This is not true because: [tex]21 \ne 23[/tex]
Option (c):
[tex]Days = 8[/tex]
[tex]Food = 3\frac{1}{8}[/tex] per day
So, we have:
[tex]Days * Food = 8 * 3\frac{1}{8}[/tex]
[tex]Days * Food = 8 * \frac{25}{8}[/tex]
[tex]Days * Food = 25[/tex] --- approximated
This is not true because: [tex]25 \ne 23[/tex]
Option (d):
[tex]Days = 11[/tex]
[tex]Food = 2\frac{1}{11}[/tex] per day
So, we have:
[tex]Days * Food = 11 * 2\frac{1}{11}[/tex]
[tex]Days * Food = 11 * \frac{23}{11}[/tex]
[tex]Days * Food = 23[/tex] --- approximated
This is true because: [tex]23 = 23[/tex]
Option (e):
[tex]Days = 7[/tex]
[tex]Food = 3\frac{2}{7}[/tex] per day
So, we have:
[tex]Days * Food = 7 * 3\frac{2}{7}[/tex]
[tex]Days * Food = 7 * \frac{23}{7}[/tex]
[tex]Days * Food = 23[/tex] --- approximated
This is true because: [tex]23 = 23[/tex]
