If an object is shot upward with an initial velocity, v0, in feet per second (ft/s), the velocity, v, in ft/s is given by the formula v=v0−32t, where t is time in seconds. Find the initial velocity of an object if the velocity after 2 seconds is 39ft/s.
Answer:
96m/s
Step-by-step explanation:
Given the velocity, v, in ft/s of an object given by the formula v=v0−32t,
Given
V = 39ft/s
t = 2secs
Required.
Initial velocity v0
Substitute the given parameters into the formula
v=v0−32t,
32 = v0-32(2)
v0 = 32+64
v0 = 96m/s
Hence the initial velocity of the object is 96m/s

x pounds of Repperts chocolate valued at $3.50 per pound is mixed with y pounds of Godiva
chocolate valued at $4.30 per pound to produce 10 pounds of a mixture selling for $39. Find x
and y, the number of pounds of each type of chocolate. write two equations and solve using elimination
!!!!PLEASE HELP!!!!
Answer:
5 pounds eachStep-by-step explanation:
Required equations:
x + y = 103.50x + 4.30y = 39Substitute x in the second equation:
x = 10 - ySolve for y:
3.5(10 - y) + 4.3y = 3935 - 3.5y + 4.3y = 390.8y = 4y = 4/0.8y = 5Then
x = 10 - 5 = 55 pounds each

An employee took 5 vacation days bringing his new vacation day balance to 8 days.Which equation can be used to find, x, the number of vacation days the employee had before using 5 vacation days?
Answer:
[tex]x + 5 = 8[/tex]
Step-by-step explanation:
Given
[tex]Total = 8[/tex]
[tex]Additional\ Vacation = 5[/tex]
Required
Determine the equation to find initial days of vacation
This is represented with x.
To get a total of 8 days vacation, we must have the following expression.
[tex]Initial\ Days + Additional\ Days = Total[/tex]
Substitute values for initial days, additional days and total. So, we have
[tex]x + 5 = 8[/tex]
Hence, the required expression is: [tex]x + 5 = 8[/tex]
A taxi driver charges a $2 fee plus an additional $4 per mile as shown by the graph.
What is the cost of a 3-mile ride?
$1
$10
$12
$14
Answer:
The answer is 14
Step-by-step explanation:
The taxi driver charges $4 per mile so you multiply that by 3 miles because that is what your trying to find. So you get 12 and from their you have to add the $2 fee thus leading to an answer of 14.

Answer:
31.01, 180.8, 0.2, 15501
Step-by-step explanation:
Puzzle 1:
The first rule takes out 301
The second rule has to have a 1 in the units place so that takes out 3.1, 3.101, and 30.1
The 3rd rule takes out 1.01, and 1.03
Rule 4, is self explanatory, so it takes out 31.3
and the last rule takes out 31.1 bc there is no hundredths column
That leaves you with 31.01
Puzzle 2:
Rule 1 takes out 18180
Rule 2, self explanatory, takes out 180
Rule 3 takes out numbers less than 18 so 1.81 and 0.18
Rule 4 takes out 18.01, 1800, 188, and 18.8
That leaves you with 180.8
Puzzle 3:
Rule 1 takes out 0.24, 0.5, and 2.02
Rule 2 takes out 0.15
Rule 3 takes out 0.02, 0.01 and 0.1 (bc it just says greater than and not equal to so it takes this one out)
Rule 4 takes out 0.12
That leaves you with 0.2
Puzzle 4:
Rule 1 takes out 45000
Rule 2 takes out 5401, 5444, and 4544
Rule 3 takes out 5454
Rule 4 does not take out any because all the remaining numbers ( 14500, 15501, 14534, and 10500) have 5 hundreds
Rule 5 takes out 14500, 14534, and 10500
That leaves you with 15501
Hope this helped :)

Express -4/-7 as a rational numbers with denominator.
1. -28
2. 7
3. 35
Step-by-step explanation:
1. -28
-4/-7 × -1/4
4/7 × -1/4 = -4/28
2. 7
-4/-7 × 1/1
4/7 × 1/1 = 4/7
3. 35
-4/-7 × 1/5
4/7 × 1/5 = 4/35

First Row: Given
Second Row: Definition of Regular Polygon
Third Row: Definition of Congruence In Terms of Rigid Motion
Fourth Row: Definition of Regular Polygon
Fifth Row: SAS Triangle Congruence Theorem
Sixth Row: CPCTC
Step-by-step explanation:
This is a basic proof in order to prove that verticals of a polygon are congruent. This should be the right answer since it's the only thing that makes sense to me. I really hope this helps you and thanks for being patient! I've been doing geometry and we have to prove everything we claim in a proof just like this one. However, there was one I kind of guessed on (the third row), but I think it should be correct! I saw from the photo that you have a check answer on the bottom of your screen. Just check the answers that I have for you now and if something is wrong, then we can continue talking about it! Hope this helps!! :)

5x+18=7x-6 what’s the answer?
Answer:
x = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
5x + 18 = 7x - 6
Step 2: Solve for x
Subtract 5x on both sides: 18 = 2x - 6Add 6 to both sides: 24 = 2xDivide both sides by 2: 12 = xRewrite: x = 12Step 3: Check
Plug in x to verify it's a solution.
Substitute: 5(12) + 18 = 7(12) - 6Multiply: 60 + 18 = 84 - 6Add/Subtract: 78 = 78And we have our final answer!
