Answer:
She has 18 nickels and 36-18= 18 dimesSolving steps:
Question: jasmine has all nickels x and dimes y in her coin jar. if she has 36 coins in all, and four more dimes than. nickels find how much money she has in her coin jar
Find: how much money she has in her coin jar
Solution: let's make an equation for this problem
She has 4 more dimes than nikels:y= x+4 Let's use this value for y in the next equation:
x+x+4= 362x= 36x= 18
she has 18 nickels and 36-18= 18 dimes
The required Jasmine has 16 nickles and 20 dimes which constitute $2.80 in her coin jar.
Let's use the given information to set up a system of equations to solve for the number of nickels (x) and dimes (y) in Jasmine's coin jar.
We are given that Jasmine has a total of 36 coins in her jar, so we have the equation:
x + y = 36 -- Equation 1
We are also given that Jasmine has four more dimes than nickels, which can be expressed as:
y = x + 4 -- Equation 2
Now, let's solve this system of equations. We can substitute Equation 2 into Equation 1 to eliminate y:
x + (x + 4) = 36
2x = 36 - 4
x = 16
Now that we have the value of x, we can substitute it back into Equation 2 to find y:
y = x + 4
y = 16 + 4
y = 20
Therefore, Jasmine has 16 nickels (x) and 20 dimes (y) in her coin jar.
To find the total amount of money she has, we need to calculate the value of the nickels and dimes separately:
Value of nickels = 0.05 * 16 = $0.80
Value of dimes = 0.10 * 20 = $2.00
The total amount of money in her coin jar is:
$0.80 + $2.00 = $2.80
Jasmine has $2.80 in her coin jar.

then switches x and y. What is the next step?
O A. Solve the equation for y.
O B. Solve the equation for x.
C. Subtract 1 from both sides of the equation.
D. Replace y with f1(x).
Answer:A
Step-by-step explanation:
The inverse of the function is y = (x +1) /2, the next step is to solve the equation for y, the correct option is A.
What is a Function?A function is a law that relates two variables namely, a dependent and an independent variable.
A function always has a defined range and domain, domain is all the value a function can have as an input and range is all the value that a function can have.
The function is f(x) = 2x -1
The inverse of a function is determined by interchanging the variables x and y and then solving for y in terms of x.
Patel replaced f(x) by y, y = 2x -1
He then switched x and y, x = 2y -1
The next step is to solve the equation for y.
2y = x +1
y = (x +1) /2

Jennifer needs to be at work at 10:10 A.M. It takes her 40 minutes to get ready in the morning and 45 minutes to drive to work. What is the latest time Jennifer can get up in the morning without being late for work?
Answer:
Jennifer will take 1h&25min to get ready, drive and reach her office. She has to start movin' at 8:45amStep-by-step explanation:
1. Calculate how many minutes it will take in total to reach work.
40 minutes to get ready
45 minutes to drive
40+45=85
85 minutes into hours =???
60 minutes = 1 hour
85-60=25
So, Jennifer will take 1 hour & 25 Minutes to go to work.
2. Calculate WHEN she will have to wake up to go to work.
10:10 is the time she HAS to be there.
so...
We know that it will take longer than 1 hour
so let's first remove 1 hour
that makes it, 9:10
now, let's remove 25 minutes
9:10, so 10 minutes gone
then 15 minutes remaining
60-15=45
so, Jennifer has to get movin' at 8:45am to reach her office at the right time.
Jennifer will take 1h&25min to get ready, drive and reach her office. She has to start movin' at 8:45am----------------------------------------------------------------------------------------------------------

Which rectangular cake gives you more to eat a vanilla cake measuring 8 in x 11 in x 13 in or a chocolate cake measuring 9 1in x 12in x 2 in?
The volume of vanilla cake is greater than the volume of chocolate cake, hence the vanilla cake gives you more to eat.
How to calculate the volume of rectangular box?The formula for calculating the volume of the cake is expressed as:
Volume of vanilla cake = 8in * 11in * 13in
Volume of vanilla cake = 1144in³
For the chocolate cake
Volume of the chocolate cake = 9.1in x 12in x 2 in
Volume of the chocolate cake = 218.4in³
Since the volume of vanilla cake is greater than the volume of chocolate cake, hence the vanilla cake gives you more to eat.

BAC rounded to 3 SF.
Step-by-step explanation:
I am not sure if I understand you right about what is needed.
I would understand we need the angle BAC (at A).
first of all, this is a right-angled triangle.
Pythagoras applies :
c² = a² + b²
with c being the Hypotenuse (side opposite of the 90° angle).
in our case that means
AC² = x² + y² = 4² + 6² = 16 + 36 = 52
AC = sqrt(52)
now we can use the law of sine to get the other angles.
a/sin(A) = b/sin(B) = c/sin(C)
with the sides and the corresponding angles being opposite.
in our case
y/sin(A) = AC/sin(B) = AC/sin(90) = AC
sin(A) = y/AC = 6/sqrt(52) = 0.832050294...
the angle A = 56.30993247...° ≈ 56.3°
Given that ABC ~ DEC, find the value of x.
Answer:
x = 4
Step-by-step explanation:
Corresponding sides of similar triangles are proportional. This fact lets us write an equation that can be solved for x.
AB/AC = DE/DC

Hope This Helps :)
The equation of the line in slope-intercept form is y = (3/5)x - 2.
To find the equation of the line in slope-intercept form (y = mx + b), where 'm' is the slope and 'b' is the y-intercept, we are given the slope (3/5) and a point on the line (0, -2).
Step 1: Use the point-slope form of the equation:
y - y₁ = m(x - x₁)
where (x₁, y₁) is the given point (0, -2) and 'm' is the slope (3/5).
Step 2: Substitute the values:
y - (-2) = (3/5)(x - 0)
Step 3: Simplify:
y + 2 = (3/5)x
Step 4: Isolate 'y' by subtracting 2 from both sides:
y = (3/5)x - 2
Now, we have the equation of the line in slope-intercept form:
y = (3/5)x - 2

There are 4,315 pistachios in the bulk bin at the grocery store. Maria wants to split the pistachios into 40 packages so that each package has the same number of pistachios with none left over. Which explains whether or not it is possible? It is possible to split the pistachios into 40 packages because each package will contain 107 pistachios. It is possible to split the pistachios into 40 packages because each package will contain 108 pistachios. It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,280 pistachios. It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,380 pistachios.
Answer:
C. It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,280 pistachios
Step-by-step explanation:
Given
[tex]Pistachios = 4315[/tex]
[tex]Packages = 40[/tex]
Required
Determine if it's possible to divide into 40 packages
First, we need to divide the Pistachios by the number of packages.
[tex]Batches = 4315/40[/tex]
[tex]Batches = 107.875[/tex]
Because, we have a decimal; then it's impossible
However,
it'd be possible if
[tex]Pistachios = 4280[/tex]
because:
[tex]4280/40 = 107[/tex]
C. It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,280 pistachios
-9 x - 17 = -26 need the answer asap !
Answer:
x = 1
Step-by-step explanation:
the important thing to know here is that if you do something to both sides of an equation (eg, add 2) the equation will still be equal.
- 9x - 17 = - 26
add 17 to both sides of the equation
-9x - 17 + 17 = -26 + 17
-9x = -9
divide both sides of the equation by -9
-9x/-9 = -9/-9
x = 1
Which change would cause a sound wave to slow down? O A. The sound passes from air into a liquid. O B. The air the sound travels through warms up. o C. The air the sound travels through cools down. O D. The sound passes from air into a solid.
Answer:
The air the sound travels through cools down.
Step-by-step explanation:
I guessed a different answer on a test but the test said this was the right answer.
C. The air the sound travels through cools down will cause a sound wave to slow down
Define sound wave ?
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air is called a sound wave
Liquid and solid will be more denser than air . So, the sound wave travel faster in them as compared to air
hence , option A. The sound passes from air into a liquid and D. The sound passes from air into a solid. are wrong options for slowing down the speed of sound wave
Heat is a from of kinetic energy , molecules at higher temperature have more energy and can vibrate faster and allow sound wave to travel more quickly , hence B. The air the sound travels through warms up. is wrong answer
correct answer is C. The air the sound travels through cools down will cause a sound wave to slow down as speed of sound as for each 1 degree Celsius that temperature decreases, the speed of sound decreases by 0.6 m/s .
