Answer:
distance divided by time
Step-by-step explanation:
distance is the speed of the moving object multiplied by the time taken to complete a certain distance therefore the speed is the distance covered divided by the time taken.

Escriba larazon entre la distancia (d)recorrida por un automóvil y el tiempo (t)empleando velocidad (v) es una razón entre distancia y el tiempo y de valor de su velocidad v=d/t
Answer:
V = d / t
Step-by-step explanation:
La velocidad se define como la relación entre la diatancia cubierta por un cuerpo y el tiempo necesario para cubrir esa distancia.
Si el tiempo empleado se da como (t)
La distancia recorrida se da como (d)
Podemos escribir la velocidad (V) en términos de disance y tiempo como;
V = d / t

(-2,1)
Step-by-step explanation:
Solve the inequality and represent your solution on the number line below.
-3x + 14< 5
Answer: X > 3
Step-by-step explanation:
You want to subtract 14 on both sides and you will get -3x < -9. Then you divide -3 on both sides -3x/3 > -9/-3 and you should end up with x < 3. Since you divided by the negative number you switch the sign from ">" to "<"

Tabi likes elimination the best so she decides that she will solve them all with elimination. Her teacher said one of the systems is set up for elimination. Which system do you think the teacher is referring to? Explain your reasoning
Answer:
System 1
Step-by-step explanation:
Tbe elemination method of solving system of equation works on such a way that :
Given two set of equation (1) and (11) having two unknowns, the Coefficient are of one of the unknowns, either x or y is the same such that applying the addition or subtraction operation of the two equations eliminates one of the unknown variables leaving us with only one unknown variable to solve, and then using this solution to solve for the other variable.
In the question given. The variable setup for elimination is the x variable such that by using the addition operation, variable x is eliminated.

Step-by-step explanation:
Find the perimeter of the triangle with vertices D(−2, −1), E(3, 2), and F(0, 4). Do not round before calculating the perimeter. After calculating the perimeter, round your answer to the nearest tenth.
Answer: [tex]15.3\ \text{units}[/tex]
Step-by-step explanation:
Given
Coordinates of the corners are D(-2,-1), E(3,2), and F(0,4)
Length DE is
[tex]\Rightarrow DE=\sqrt{(2+1)^2+(3+2)^2}\\\Rightarrow DE=\sqrt{(3)^2+(5)^2}\\\Rightarrow DE=\sqrt{34}\ \text{units}[/tex]
Length EF is
[tex]\Rightarrow EF=\sqrt{(4-2)^2+(0-3)^2}\\\Rightarrow EF=\sqrt{(2)^2+(-3)^2}\\\Rightarrow EF=\sqrt{13}\ \text{units}[/tex]
Length FD is
[tex]\Rightarrow FD=\sqrt{(4+1)^2+(0+2)^2}\\\Rightarrow FD=\sqrt{(5)^2+(2)^2}\\\Rightarrow FD=\sqrt{29}\ \text{units}[/tex]
Perimeter of the triangle is
[tex]\Rightarrow DE+EF+FD=\sqrt{34}+\sqrt{17}+\sqrt{29}\\\Rightarrow DE+EF+FD=15.3\ \text{units}[/tex]
On a windy day, a 90 foot rope tightly secures a hot air balloon to a stake in the ground. From the balloon, the angle of depression of the stake is 62º. Find the height of the balloon to the nearest foot.
List your knowns and unknowns.
Solve the problem. Make sure your answer contains units and is labeled clearly.
Check your answer.
Write 2-4 sentences explaining your solution/checking process.
Answer:
79 ftStep-by-step explanation:
Balloon - B, stake - S, point at ground - G
Given:
BS = 90 ftm∠BSG = 62°BG = xUse sine and solve for x:
BG/BS = sin ∠BSGsin 62° = x / 90x = 90 sin 62 degx = 79 ft (rounded)The function f(x) is multiplied by a factor of 2 and then 3 is added to the function.
f(x) = sin(x)
What effect does this have on the graph of the function?
A.) The graph is vertically compressed by a factor of 3 and shifted up 2 units.
B.) The graph is vertically stretched by a factor of 3 and shifted up 2 units.
C.) The graph is vertically compressed by a factor of 2 and shifted up 3 units.
D.) The graph is vertically stretched by a factor of 2 and shifted up 3 units.
Given:
The function is:
[tex]f(x)=\sin x[/tex]
The function f(x) is multiplied by a factor of 2 and then 3 is added to the function.
To find:
The effect on the graph of the function.
Solution:
The transformation is defined as
[tex]g(x)=kf(x)+b[/tex] .... (i)
Where, k is stretch factor and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
It is given that the function f(x) is multiplied by a factor of 2 and then 3 is added to the function. So, the new function is:
[tex]g(x)=2f(x)+3[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]k=2[/tex], it means the graph is vertically stretched by a factor of 2.
[tex]b=3[/tex], it means the graph is shifted up 3 units.
Therefore, the correct option is D.
Answer:
D.) The graph is vertically stretched by a factor of 2 and shifted up 3 units

Kesha borrowed $1,800 at 5% SIMPLE INTEREST. How much did Kesha owe after 6 months?
Interest: $
Total she owed: $
Answer:
Use Simple Interest Formula=PrT/100
SI=$1800×5×6/12÷100
=4500/100
=$45
Step-by-step explanation:
$45 is the interest that's gonna be owed after 6months so therefore the total $ she owed after 6 months would be: $45 + $1,800=$1,845.

List the first three terms of this sequence: an = 3 • 5n – 1
Answer:
1st term = 14
2nd term = 29
3rd term = 44
Step-by-step explanation:
1st term = 3 x (5 x 1) - 1
= 3 x 5 - 1
= 15 - 1 = 14
2nd term = 3 x (5 x 2) - 1
= 3 x 10 - 1
=30 - 1 = 29
3rd term = 3 x (5 x 3) -1
= 3 x 15 - 1
= 45 - 1 = 44

‘I-Moons’ charges $12 per album downloaded and an initial joining fee of $3. ‘I-Toons’ Charges $10 per album downloaded and a joining fee of $9. Write a system of linear equations that models this situation. Determine how many albums (x) it will take for the cost (y) to be the same. What does that cost?
Answer:
y = 3 + 12x - - - (1)
y = 9 + 10x - - - (2)
3 albums
$39
Step-by-step explanation:
Let number of download = x
Given :
I-moon :
Initial joining fee = $3
Cost per download = $12
Hence,
y = 3 + 12x - - - (1)
I - Toons :
Initial joining fee = $9
Cost per download = $10
y = 9 + 10x - - - (2)
For cost to be the same ;
Equate (1) and (2)
3 + 12x = 9 + 10x
Collect like terms
3 - 9 = 10x - 12x
-6 = - 2x
x = 3
It will take 3 albums
Cost :
3 + 12(3)
3 + 36 = 39
SOMEONE HELP, I HAVENT BEEN PAYING ATTENTION TO CLASS
Answer:
A=4cm
ok to do this we do the formula
A=PiR^2
A=3.14*4^2
A=3.14*16
A=50.24
and the area of circle B is 4 times the area of a so
50.24*4=200.96
200.96=3.14*X^2
Since r is on the right side of the equation, switch the sides so it is on the left side of the equation. 3.14 ⋅ r 2 = 200.96 Divide each term by 3.14 and simplify.
r 2 = 64
r=8
CIRLCE A=50.24
CIRLCE B=8
Which could be the dimensions of a rectangular prism whose surface area is greater than 140 square feet? Select three options.
Answer:
6 feet by 5 feet by 4 feet
7 feet by 6 feet by 4 feet
Step-by-step explanation:
The surface are of rectangular prism = 140 ft²
Surface area of rectangular prism is given by :
A = 2(lw + lh + wh)
Using trial by error method :
6 feet by 2 feet by 3 feet
A = 2(6*2 + 6*3 + 2*3) = 72ft²
6 feet by 5 feet by 4 feet
A = 2(6*5 + 6*4 + 5*4) = 148 ft²
7 feet by 6 feet by 4 feet
A = 2(7*6 + 7*4 + 6*4) = 188ft²
8 feet by 4 feet by 3 feet
A = 2(8*4 + 8*3 + 4*3) = 136ft²
Which statement is true?
(1) B and C have the same zeros.
(2) A and B have the same y-intercept.
(3) B has a minimum and C has a maximum.
(4) C has a maximum and A has a minimum.
You buy a car for 20,000 dollars and pay 5% in tax. How much is the tax?
Answer: $1,000
Step-by-step explanation:
We are trying to find 5% of 20,000. Always remember that the "of" can be changed to a multiplication, and that "percent" means per hundred. So you will write (5/100) x 20,000 = 0.05 x 20,000 = $1,000.00
Please could someone explain me why the answer is not 10x5?
Answer:
20x^5
