A car travelling north at 48 km/hr is approaching an intersection. A truck travelling East at 60 km/hr is moving away from the same intersection. How is the distance between the car and the truck changing when the car is 9 m from the intersection and the truck is 40 m from the intersection?
The rate at which the distance between the car and the truck is changing when the car is 9 m from the intersection and the truck is 40 m from the intersection is about 19.187 m/s
What is the rate of change of a function?The rate of change of a function is an indication of how fast the function's output changes per unit change in the input of the function.
Let y represent the distance of the car from the intersection, and let x represent the distance of the truck from the intersection, we get;
The distance between the car and the truck, d, can be obtained from Pythagorean Theorem as follows;
d² = y² + x²
2·d·d/dt = 2·y·dy/dt + 2·x·dx/dt
dy/dt = The speed of the car = 48 km/h = 40/3 m/s
dx/dt = The speed of the truck = 60 km/h = 50/3 m/s
y = The distance of the car from the intersection = 9 m
x = The distance of the truck from the intersection = 40 m
d² = 9² + 40² = 1681
d = √(1681) = 41
d = 41 m
Therefore;
2×41×d/dt = 2×9 × 40/3 + 2 × 40 × 50/3 = 4720/3
d/dt = 4720/3/(2 × 41) = 2360/123 ≈ 19.187
d/dt ≈ 19.187 m/s
The rate of change distance between the car and the truck d/dt is about 19.187 m/s

Anna, Betty and Candy shared a box of sweets. Anna took 8 more than 1/3 of the number of sweets in the box. Betty took 18 more than half of the remaining number of sweets . If Candy took the last 6 sweets, how many sweets were there in the box at first?
Answer: 108
Step-by-step explanation: Let the total number of sweets be x
Therefore, Anna - (x/3)+8
After Anna, remaining amount is x - ((x/3)+8) = 2x/3 + 8
Betty took (2x/3 + 8)/2 + 18 = x/3 + 22
Remaining = x - ((x/3)+8) - (x/3 + 22) = x/3 -30
Candy took the rest which is 6 i.e.
x/3 - 30 = 6
x/3 = 36
x = 108
What happens at equilibrium price and quanity? 1.The quantity supplied equals the quantity demanded.
2.The price demanded equals the price supplied.
3.The priced demanded equals the quantity supplied.
4.The quantity supplied equals the price demanded.
Answer:
Step-by-step explanation:
At equilibrium price and quantity, the answer is 1. The quantity supplied equals the quantity demanded.
This means that the market is in a state of balance, where the quantity of a good or service that producers are willing to supply is exactly the same as the quantity that consumers are willing to buy. As a result, there is no excess supply or excess demand, and the price of the good or service is stable.

A college student realized that he was spending too much money on music. For the remaining 5 months of the year his goal is to spend a
mean of $60 a month towards music. How much can he spend in December, taking into consideration that in the other 4 months he
spent $65, $55, $70, and $75, respectively? Round your answer to two decimal places, if necessary.
The college student can spend $35 in December to achieve his goal of a mean spending of $60 per month for the remaining five months.
To find out how much the college student can spend in December, we need to consider the total amount he has already spent in the first four months and his goal of having a mean spending of $60 per month for the remaining five months.
Let's calculate the total amount spent in the first four months:
Total spent = $65 + $55 + $70 + $75 = $265
The student's goal is to spend a mean of $60 per month for the remaining five months. Since there are five months remaining, the total amount he plans to spend is:
Total planned spending = $60 * 5 = $300
To find out how much he can spend in December, we subtract the total spent in the first four months from the total planned spending:
Amount he can spend in December = Total planned spending - Total spent
= $300 - $265
= $35

The students of. a school fill 5 1/4 buses for a field trip each class fils 3/4 bus how many classes are riding on the buses pls show me step by step
Let us use the equality postulate.
Since each class fills 3/4 bus, we will say:
1 class = 3/4 buses
For us to get the number of classes riding on the 5 1/4 buses for the field trip, we will express this as:
x classes = 5 1/4 buses
Solving both expression
1 class = 3/4 buses
x classes = 5 1/4 buses
you will need to cross multiply from here:
3/4 * x = 1 * 5 1/4
3/4 x = 21/4
multiply both sides by 4
3x/4 * 4 = 21/4 * 4
3x = 21
Divide both sides by 3:
3x/3 = 21/3
x = 7
Therefore 7 classes are riding on the bus.

Heather is making chocolate biscuits
she has:
2kg of flour
1kg of butter
340g of icing sugar
200g of chocolate
here is the list of ingredients for making 20 biscuits.
100g of flour
120g of butter
80g of icing sugar
25g of chocolate
work out how mnany bisuits she can make
Therefore, Heather can make a maximum of 4 biscuits with the given ingredient quantities.
To determine how many biscuits Heather can make, we need to compare the amount of each ingredient required for a single biscuit to the total amount of ingredients she has.
Let's calculate the number of biscuits she can make based on the ingredient quantities provided:
First, we need to find the ratio of each ingredient required per biscuit:
Flour: 100g per biscuit
Butter: 120g per biscuit
Icing sugar: 80g per biscuit
Chocolate: 25g per biscuit
Next, we divide the total amount of each ingredient by the respective ratio to find the maximum number of biscuits she can make:
Flour: 2kg / 100g = 20 biscuits
Butter: 1kg / 120g = 8.33 biscuits (approximately)
Icing sugar: 340g / 80g = 4.25 biscuits (approximately)
Chocolate: 200g / 25g = 8 biscuits
Since we can only make a whole number of biscuits, the limiting factor is the icing sugar. Heather can only make 4 biscuits since she has 4.25 times the required amount of icing sugar.

which equation matches the graph answers A(y = 12x) B(y = 1/4x) C(y = 4x). D( y = x)please help
There's two ways of answering this. You can either check if the points marked on the graph matches each option, or you can also get the equation of the line from the graph.
I'll do the second way. To do this we can see that points (3,12) and (1,4) are marked on the line. And we know that the general equation of a line is:
\(y=mx+b\)'m' is the slope and b is the point where the line crosses the 'y' axis. We can see from the graph that b = 0, since the line goes through the origin. So our equation will be something like this:
\(y=mx\)Finally, to find the slope we use the points. If we have two pair of points (x1,y1) and (x2,y2), the slope is:
\(m=\frac{y_2-y_1}{x_2-x_1}\)In this case, this is:
\(m=\frac{12-4}{3-1}=\frac{8}{2}=4\)So, the equation for this graph is:

A: x+90=180
B: 2x+90=180
C: x-90=180
D: Not enough info
Answer:
(B) 2x + 90 = 180 is an equation that could be used to find x.
Step-by-step explanation:
Observing at the triangle, we can see that..
- We are aware of two angel measurements, both of which are 45 degrees.
One triangle is exactly 180 degrees and if you add both 2 angel measurements from the triangles...
45 + 45 = 90 degrees
180 - 90 = 90 degrees
As a result, we know that x = 90. Now we find the equation. Lets look at equation B. ( 2x + 90 = 180 )
Step 1 : 90 should be subtracted from both sides.
2x + 90 − 90 = 180 − 90
2x = 90
Step 2 : Divide both sides by 2.
(When I use the symbol /, it signifies I'm dividing.)
2x/2 = 90/2
x = 45
Step 3: Examine your solution to see whether it is right.
2x + 90 = 180
2(45) + 90 = 180
90 + 90 = 180 ✓
This shows that 2x + 90 = 180 is an equation that could be used to find x.

The graph shows the relationship between the distance a truck can travel and the amount of gasoline used. What is the unit rate for the distance traveled to the amount of gasoline used?Enter your answer in the box.
We need to find the unit rate for this situation.
The graph represents a linear equation. Therefore, the unit rate will be found by getting the slope of the line.
The slope is given by the next formula:
\(m=\frac{y_2-y_1}{x_2-x_1}\)Where m= slope
P1(x1,y1) and P2(x2,y2) are points for the graph
Let's use the given points P1(1,7) and P=(5,35)
Replacing the values:
\(m=\frac{35-7}{5-1}\)Then
\(m=\frac{28}{4}\)\(m=7\)Hence, we found that the unit rate for the situation is given by 7 miles per gallon.
Which has a greater average rate of change over the interval where -1≤x≤3; the function
g(x)=x²+6x or the function f(x) = 2*. Provide justification for your answer.
Answer: Step-by-step explanation:
To find the average rate of change of a function over an interval, we can use the following formula:
average rate of change = (y2 - y1)/(x2 - x1)
Where x1 and x2 are the values of x at the beginning and end of the interval, and y1 and y2 are the corresponding values of the function at those points.
In this case, we are asked to compare the average rate of change of the functions g(x) and f(x) over the interval where -1≤x≤3.
For the function g(x) = x²+6x, we can plug in the given values for x1, x2, y1, and y2 to find the average rate of change:
average rate of change = (g(3) - g(-1))/(3 - (-1))
= (9 + 18 - (1 - 6))/(4)
= 27/4
= 6.75
For the function f(x) = 2, we can plug in the given values for x1, x2, y1, and y2 to find the average rate of change:
average rate of change = (f(3) - f(-1))/(3 - (-1))
= (2 - 2)/(4)
= 0
Since the average rate of change of the function g(x) is greater than the average rate of change of the function f(x), the function g(x) has a greater average rate of change over the interval where -1≤x≤3.
I hope this helps clarify the comparison of the average rate of change for these two functions. Do you have any other questions?
