kelly bought some stuffed animals for 6.49 each she also got a box fo chocolate for 8.32 she paid a total of 27.79 to write an equation to find how many stuffed animals kelly purchased
Answer:
3
Step-by-step explanation:
She only bought one chocolate so you will subtract 8.32 from her total, 27.79, when you do that you will get 19.47. You do that so you can know the total of the stuffed animals by them self. Then all you have left in the total is her stuffed animals so you divide 19.47 by 6.49, when you do that you get three, so that means that she got three stuffed animals.
Step-by-step explanation:
thats the answer right there

What is the inverse of the function
Answer:
1/2x -1/2
Step-by-step explanation:
f(x) = 2x+1
y = 2x+1
Switch x and y
x = 2y+1
Solve for y
Subtract 1
x-1 = 2y+1-1
x-1 =2y
Divide by 2
(x-1)/2 = 2y/2
1/2x -1/2 = y
The inverse is 1/2x -1/2
Answer:
[tex]\huge\boxed{h(x) = \frac{1}{2} x - \frac{1}{2}}[/tex]
Step-by-step explanation:
[tex]f(x) = 2x+1[/tex]
Put f(x) = y
[tex]y = 2x + 1[/tex]
Interchange x and y
[tex]x = 2y+1[/tex]
Solve for y
[tex]x = 2y+1[/tex]
Subtracting 1 to both sides
[tex]x-1 = 2y[/tex]
Dividing both sides by 2
[tex]\frac{x-1}{2} = y \\\\ OR\\\\ y = \frac{x-1}{2}[/tex]
Put y = h(x)
[tex]\bold{h(x) = \frac{1}{2} x - \frac{1}{2}}[/tex]
What is the area of a rectangle with a dimension of 5 cm and 3/4 cm? PLEASE EXPLAIN AND I WILL MARK YOU BRAINLIEST.
Answer:
3.75 cm^2
Step-by-step explanation:
Area of a rectangle = Length x Width.
If we are given that the length is 5 cm and width is 3/4 cm ( you could convert this to a 0.75 if you want to as well ) we can plug this in:
Area = 5 cm x 3/4 cm
Solving for Area we get:
Area = 3.75 cm^2.
Answer:
[tex] \boxed{ \bold{ \huge{ \bold{ \boxed{ \sf{3.75 \: {cm}^{2} }}}}}}[/tex]
Step-by-step explanation:
Length ( l ) = 5 cm
Width ( w ) = 3/4 cm
To find : Area of a rectangle
Finding the area of a rectangle having length of 5 cm and width of 3/4 cm
[tex] \boxed{ \sf{area \: of \: rectangle = \: l \times w}}[/tex]
plug the values
[tex] \dashrightarrow{ \sf{5 \times \frac{3}{4} }}[/tex]
To multiply one fraction by another, multiply the numerators for the numerator, and multiply the denominator for its denominator.
[tex] \dashrightarrow{ \sf{ \frac{5 \times 3}{4} }}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{15}{4} }}[/tex]
Divide 15 by 4
[tex] \dashrightarrow{ \sf{3.75 \: {cm}^{2} }}[/tex]
Hope I helped!
Best regards! :D
Help please also give an explanation
Answer:
The answer is option AStep-by-step explanation:
[tex] \frac{a + bc}{wd + f} = g[/tex]First of all cross multiply
That's
g( wd + f ) = a + bc
Multiply the terms at the left side of the equation
We have
gwd + fg = a + bc
Send fg to the right side of the equation
That's
gwd = a + bc - fg
Divide both sides by dg to make W stand alone
[tex] \frac{gwd}{dg} = \frac{a + bc - fg}{dg} [/tex]We have the final answer as
[tex]w = \frac{a + bc - fg}{dg} [/tex]Hope this helps you

A jar contains 2 caramels, 7 mints, and 16 dark chocolates. What is the probability of choosing a dark chocolate, eating it and then choosing a caramel?
Answer: dark chocolate 16/25 carmel 1/12
Step-by-step explanation:
there are 16 dark chocolates
to find the probability you have to add up all of your numbers
2+7+16= 25
so the probablity of drawing a dark chocolate is 16/25
repeat the steps but subtract 1 from the total since you ate one you didn't put it back.
so the probability of drawing a carmel is 2/24 or simplified 1/12

y^2+3y-10=0 please solve
The Answer is: y=2,5
Answer:
y = -5
y = 2
Step-by-step explanation:
Find 2 factors of -10 that add up to 3
This will be 5 and -2
So, we can factor this:
y² + 3y -10 = 0
(y + 5)(y - 2) = 0
Set each factor equal to 0 and solve:
y + 5 = 0
y = -5
y - 2 = 0
y = 2
So, the solutions are y = -5 and y = 2

In the drawing above two rugby players start 41 meters apart at rest. Player 1 accelerates at 2.2 m/s^2 and player 2 accelerates at 1.7 m/s^2. How much time elapses before the players collide?
Answer:
The time that elapses before the players collide is 4.59 secs
Step-by-step explanation:
The distance between the two players is 41 meters. Hence, they would have total distance of 41 meters by the time they collide.
We can write that
S₁ + S₂ = 41 m
Where S₁ is the distance covered by Player 1 before collision
and S₂ is the distance covered by Player 2 before collision
From one of the equations of kinematics for linear motion,
[tex]S = ut[/tex] + [tex]\frac{1}{2} at^{2}[/tex]
Where [tex]S[/tex] is distance
[tex]u[/tex] is the initial velocity
[tex]a[/tex] is acceleration
and [tex]t[/tex] is time
Since the players collide at the same time, then time spent by player 1 before collision equals time spent by player 2 before collision
That is, t₁ = t₂ = t
Where t₁ is the time spent by player 1
and t₂ is the time spent by player 2
For player 1
[tex]S[/tex] = S₁
[tex]u[/tex] = 0 m/s ( The player starts at rest)
[tex]a[/tex] = 2.2 m/s²
Then,
S₁ = [tex]0(t)[/tex] + [tex]\frac{1}{2} (2.2)t^{2}[/tex]
S₁ = [tex]1.1t^{2}[/tex]
[tex]t^{2} = \frac{S_{1} }{1.1}[/tex]
For player 2
[tex]S[/tex] = S₂
[tex]u[/tex] = 0 m/s ( The player starts at rest)
[tex]a[/tex] = 1.7 m/s²
Then,
S₂ = [tex]0(t)[/tex] + [tex]\frac{1}{2} (1.7)t^{2}[/tex]
S₂ = [tex]0.85t^{2}[/tex]
[tex]t^{2} = \frac{S_{2} }{0.85}[/tex]
Since the time spent by both players is equal, We can write that
[tex]t^{2}[/tex] = [tex]t^{2}[/tex]
Then,
[tex]\frac{S_{1} }{1.1} = \frac{S_{2} }{0.85}[/tex]
[tex]0.85S_{1} = 1.1S_{2}[/tex]
From, S₁ + S₂ = 41 m
S₂ = 41 - S₁
Then,
[tex]0.85S_{1} = 1.1 ( 41 -S_{1} )[/tex]
[tex]0.85S_{1} = 45.1 - 1.1S_{1}[/tex]
[tex]0.85S_{1} + 1.1S_{1} = 45.1 \\1.95S_{1} = 45.1\\S_{1} = \frac{45.1}{1.95} \\S_{1} = 23.13 m[/tex]
This is the distance covered by the first player. We can then put this value into [tex]t^{2} = \frac{S_{1} }{1.1}[/tex] to determine how much time elapses before the players collide.
[tex]t^{2} = \frac{S_{1} }{1.1}[/tex]
[tex]t^{2} = \frac{23.13 }{1.1}[/tex]
[tex]t^{2} = 21.03\\t = \sqrt{21.03} \\t = 4.59 secs[/tex]
Hence, the time that elapses before the players collide is 4.59 secs
