"A freely falling object experiences gravity. The value of gravity is 9.8 m/s2 or 980 cm/s2. The equation that describes the distance an object falls from rest under the influence of gravity is?"
Answer:
S =4.9t²
Step-by-step explanation:
Using the equation of motion
S =ut+1/2gt²
u is the initial speed = 0m/s
t is the time
g I the acceleration due to gravity = 9.8m/s²
S is the distance of the object
Substitute
S = 0(t)+1/2 (9.8)t²
S = 0+4.9t²
S = 4.9t²
Hence thee equation that describes the distance an object falls from rest under the influence of gravity is S = 4.9t²

The right rectangular prism shown below is made of equal-sized cubes. The side length of each cube is 2 1/2 inches. What is the volume in cubic inches, of the right rectangular prism?
The image of the right rectangular prism is missing, so i have attached it.
Answer:
volume of the right rectangular prism = 625 in³
Step-by-step explanation:
The rectangular prism is made of equal-sized cubes. Thus, let's first find the volume of 1 cube.
Formula for volume of one cube is;
V = a³
where
a is the length of one side of the cube
We are told that this length is 2½ inches
Thus;
a = 2½ = 5/2 inches
>> V = (5/2)³
>> V = 125/8 in³
Now, in the rectangular prism attached, if we count the number of cubes we have, it is equal to 40 cubes
Therefore, the volume of the prism is;
Volume of one cube × 40
>> volume of the prism = (125/8) × 40
volume of the prism = 625 in³

The Science Club went on a two-day field trip. The first day the members paid $40 for transportation plus $19 per ticket to the planetarium. The second day they paid $90 for transportation plus $16 per ticket to the geology museum. Write an expression to represent the total cost for two days for the n members of the club.
Answer:
total cost = $130 + $35n
Step-by-step explanation:
Cost incurred on the first day.
Fixed cost = $40. this amount is fixed because it does not depend on the number of students that take the trip
variable cost = $19n. It is variable because it depends on the number of students that take the trip. the more the club members that take the trip, the higher the cost
Total cost on the first day = $40 + $19n
Cost incurred on the second day
Fixed cost = $90. this amount is fixed because it does not depend on the number of students that take the trip
variable cost = $16n. It is variable because it depends on the number of students that take the trip. the more the club members that take the trip, the higher the cost
Total cost on the second day = $90 + $16n
Total cost incurred would be the sum of the two costs incurred on the two days
total cost = $40 + $19n + $90 + $16n
= $130 + $35n
30 POINTS PLEASE HELP ASAP !!!
Answer:
1: x = 29
2: Angle C is 93 degrees
Step-by-step explanation:
For 1 angle C has to equal 93 degrees since 52 + 35 = 87 and 180 - 87 = 93, and a triangles interior angles add up to 180 degrees.
From there create an equation: 3(x + 2) = 93 then solve
3x + 6 = 93
-6 from both sides
3x = 87
/3 from both sides
x = 29
For 2 just plug in x (29)
3(29 + 2)
87 + 6
93

The question says “the system below has been solved by graphing. How many solutions does it have?”
Answer:
Infinitely many solutions
Step-by-step explanation:
3x+y=1
15x+5y=5
Step: Solve3x+y=1 for y:
3x + y +−3 x = 1 + −3x (Add -3x to both sides)
y=−3x+1
Step: Substitute−3x+1 for y in 15x+5y=5:
15x+5y=5
15x+5(−3x+1)=5
5=5(Simplify both sides of the equation)
5+−5=5+−5(Add -5 to both sides)
0=0
so there are infinite solutions

What is the value of b and the value of c? Picture of triangle down below.
b=
c=
Answer:
b = 73
c = 34
Step-by-step explanation:
<T and <R are equal because they are opposite equal sides.
So b = 73°
Every triangle has 180 degrees
b + c + 73 = 180
73 + c + 73 = 180
146 + c = 180
c = 180 - 146
c = 34
Simplify: 7(-2x - 3) *

in isosceles trapezoid EFGH, FG parallel EH, FG=10, GH=12, and ∠E=60. Find the area of EFGH.
Answer:
22√3 units squared
Step-by-step explanation:
1) Draw the trapezoid
2) Notice you have to find the height to find the area of the trapezoid
3) Notice it is a 30 60 90 triangle when you draw the line to find the height
4) Solve for the 30 60 90 triangle and you get the height to be 2√3
5) Solve for the area of the trapezoid using this formula A= 1/2 h ( b1 + b2)
6) Fill in the numbers for the equation A= 1/2∙ 2√3 ( 10 + 12)
7) Keep aside the 1/2 for now
8) Simplify equation 2√3 + 22 or 2√3 + (10 + 12)
9) Simplify further 44√3
10) Now bring back the 1/2 and put it in the equation 1/2∙ 44√3
11) Simplify to get 22√3
12) 22√3 is the area of the trapezoid
13) 22√3 units squared is the final answer
I will put a my drawing of the trapezoid for reference and this is what I used to solve the question.
If you want to know how I solved the 30 60 90 triangle please let me know.
