Jada has p pennies and n nickels that add up to more than 40 cents. She had fewer than 20 coins altogether. Write a system of inequalities that represent how many pennies and nickels that jada could have.
Answer:
5n+p>40
n+p<20
Step-by-step explanation:
Since pennies are worth 1 cent and nickels 5, using n as the number of nickels and p as the number of pennies, we can say that 5*n+1*p>40. Then, n+p is less than 20, so n+p<20. Our answer is then
5n+p>40
n+p<20
The currency called the dollar can be split into smaller forms called nickels, pennies, dimes, and quarters.
The system of inequalities that represents how many pennies and nickels that Jada could have is given as:
p + n < 200.01p + 0.05n > 0.40Let's represent the number of :
pennies = p
nickels = n
It is important to also note that:
1 penny = $0.01
1 nickel = $0.05
40 cents can also be written as: $0.40
Jada has p pennies and n nickels that add up to more than 40 cents.
The word more than means greater than and this can be represented by the inequality sign ">". Hence, our inequality equation is given as:
$0.01 x p + $0.05 x n > $0.40
0.01p + 0.05n > 0.40
She had fewer than 20 coins altogether.
The word fewer means less than and this can be represented by the inequality sign "<". Hence, our inequality equation is given as:
p + n < 20
Therefore, the system of inequalities that represents how many pennies and nickels that Jada could have is given as:
p + n < 200.01p + 0.05n > 0.40To learn more, visit the link:

whilst this is being answered, I'm going to be doing other homework, so good luck answering this one
It would take 13 buses to get everyone to the zoo
It would take 26 vans to get everyone to the zoo
It would be cheaper to rent buses
Step-by-step explanation:
The given is:
A school is taking 388 students on a field trip to the zooThey can rent buses that hold 30 students for $895 eachThey can rent vans that hold 15 students for $450 eachWe need to find how many buses it would take to get everyone to the zoo, how many vans it would take to get everyone to the zoo, and would it be cheaper to rent
∵ The number of students is 388
∵ Each bus can hold 30 students
- Divide the number of students by 30 to find the number of buses
∴ The number of buses = 388 ÷ 30 = 12.92
- They must to rent 13 bus to hold all the students
∴ The number of buses is 13
It would take 13 buses to get everyone to the zoo
∵ The number of students is 388
∵ Each van can hold 15 students
- Divide the number of students by 15 to find the number of vans
∴ The number of vans = 388 ÷ 15 = 25.87
- They must to rent 26 vans to hold all the students
∴ The number of vans is 26
It would take 26 vans to get everyone to the zoo
Let us find the cost of rent of the buses and vans to find which of them is cheaper
∵ The cost of rent of each bus = $895
∵ The number of buses = 13
∴ The cost of rent the buses = 13 × 895 = $11635
∵ The cost of rent of each van = $450
∵ The number of vans = 26
∴ The cost of rent the buses = 26 × 450 = $11700
∵ $11635 < $11700
∴ The cost of rent the buses < the cost of rent the vans
∴ The buses is cheaper than the vans
It would be cheaper to rent buses

Final answer:
To determine when two bells will next ring together, find the Least Common Multiple (LCM) of their ringing intervals. The LCM of 10 and 25 is 50, therefore the bells will next ring together at 6:50 a.m.
Explanation:
The question is about finding the next time two bells, ringing at different intervals, will ring together. To solve this, we need to find the Least Common Multiple (LCM) of the two bell ringing intervals: 10 minutes and 25 minutes. The LCM of 10 and 25 is 50 since 10 × 5 = 50 and 25 × 2 = 50. Since the bells start ringing together at 6 a.m., they will next ring together 50 minutes later.
Adding 50 minutes to 6 a.m., we get 6:50 a.m. Therefore, the two bells will next ring together at 6:50 a.m.

The distance traveled, in meters, of a coin dropped from a tall building is modeled by the equation d(t) = 4.9t2 where d equals the distance traveled at time t seconds and t equals the time in seconds. What does the average rate of change of d(t) from t = 3 to t = 6 represent?

The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.
The coin travels an average distance of 14.7 meters from 3 seconds to 6 seconds.
PLEASE HELP!!
The average rate of change of d(t) from t = 3 to t = 6 represent: A. The coin travels an average distance of 44.1 meters from 3 seconds to 6 seconds.
In Mathematics and Geometry, the average rate of change (ARoC) of a function f(x) on a closed interval [a, b] can be calculated by using this mathematical equation (formula):
Average rate of change (ARoC) = [tex]\frac{f(b) - f(a)}{(b - a)}[/tex]
Based on the given quadratic function, we can reasonably infer and logically deduce the following:
[tex]d(t)=4.9t^2\\\\d(3)=4.9(3)^2[/tex]
f(a) = d(3) = 44.1
[tex]d(t)=4.9t^2\\\\d(6)=4.9(6)^2[/tex]
f(a) = d(3) = 176.4
Next, we would determine the average rate of change (ARoC) of the function over the interval [3, 6]:
Average rate of change (ARoC) = [tex]\frac{176.4 - 44.1}{(6 - 3)}[/tex]
Average rate of change (ARoC) = 44.1 meters.
In this context, we can logically deduce that the coin travels an average distance of 44.1 meters from 3 seconds to 6 seconds.

What is 28 is 35% of what number
Answer:
80
Step-by-step explanation:
35/100X = 28
35X = 2800
2800/35=80
Answer: 80
Step-by-step explanation: To answer the question 28 is 35% off what number, we translate the question into an equation.
So we have "28 is" which means 28 = 35% which we need to write as a decimal. To write a percent as a decimal, we move the decimal point 2 places to the left so 35% can be written as the decimal .35. Next we have "of what number" which means times X.
Now we have the following equation.
28 = (.35) (x)
Now to solve for x since x is being multiplied by .35, we need to divide by .35 on both sides of the equation.
On the right side of the equation, the .35's cancel and we have x. On the left side of the equation, we have 28 ÷ .35 which is 80.
So 80 = x.
Therefore, 28 is 35% of 80.

3(x^2+4x)+4(y^2-2y)=32
Answer:
3x^2 + 12x + 4y^2 - 8y = 32
Step-by-step explanation:
3(x^2+4x)+4(y^2-2y)=32
At first we have to break the parenthesis to get the variables in normal position. To break those, we have to multiply each with the help of algebraic expression:
or, (3*x^2) + (3 × 4x) + (4 × y^2) - (4 × 2y) = 32
or, 3x^2 + 12x + 4y^2 - 8y = 32
Since the equation does not have anything to add or deduct, therefore, it is the answer.
A survey showed that 35% of the students prefer plain white milk over chocolate milk. If the school has 1200 students. How many students prefer chocolate milk?
780 students prefer chocolate milk.
Step-by-step explanation:

A 6000-seat theater has tickets for sale at $28 and $40. How many tickets should be sold at each price for a sellout performance to generate a total revenue of $189600?
Answer:
4200 tickets of [tex]\$28[/tex] and 1800 tickets of [tex]\$40[/tex] were sold
Step-by-step explanation:
Given:
Tickets are sold at price [tex]\$28[/tex] and [tex]\$40[/tex].
Let Number of tickets sold at price [tex]\$28[/tex] be [tex]x[/tex].
Let Number of tickets sold at price [tex]\$40[/tex] be [tex]y[/tex].
Theater has maximum capacity of 6000 seat.
Hence,
[tex]x+y=6000 \ \ \ \ equation \ 1[/tex]
Total revenue to be generated is [tex]\$189600[/tex]
[tex]\therefore 28x + 40y= 189600 \ \ \ \ equation \ 2[/tex]
Now Multiplying equation 1 by 40 we get,
[tex]x+y=6000\\40x+40y=240000\ \ \ \ equation \ 3[/tex]
Now Subtracting equation 2 by equation 3 we get,
[tex](40x+40y=240000)- (28x + 40y= 189600)\\12x=50400\\\\x=\frac{50400}{12}=4200[/tex]
Now substituting value of x in equation 1 we get,
[tex]x+y=6000\\4200+y=6000\\y=6000-4200= 1200[/tex]
Hence a total of 4200 tickets of [tex]\$28[/tex] and 1800 tickets of [tex]\$40[/tex] were sold
To generate a total revenue of $189,600, 4200 tickets should be sold at $28 and 1800 tickets should be sold at $40.
Explanation:To find the number of tickets to be sold at each price, we can set up a system of equations. Let's assign variables:
Let x be the number of tickets sold at $28.
Let y be the number of tickets sold at $40.
The total revenue from selling x tickets at $28 is 28x, and the total revenue from selling y tickets at $40 is 40y. Since the total revenue is $189,600, we can write the equation:
28x + 40y = 189,600
We also know that the total number of tickets sold is x + y = 6000.
We can solve this system of equations to find the values of x and y. One way is to multiply the second equation by 28 and subtract it from the first equation:
28x + 40y - 28x - 28y = 189,600 - 28(6000)
12y = 189,600 - 168,000
12y = 21,600
y = 21,600 / 12 = 1800
Substituting the value of y in the equation x + y = 6000, we get:
x + 1800 = 6000
x = 6000 - 1800 = 4200
Therefore, 4200 tickets should be sold at $28 and 1800 tickets should be sold at $40 to generate a total revenue of $189,600.

3. A model rocket is launched from the ground with an initial velocity of 352 ft/sec.
e. How long will it take the rocket to reach its maximum height? Show all work in the space provided.
f. Assume the model rocket’s parachute failed to deploy and the rocket fell back to the ground. How long would it take the rocket to return to Earth from the time it was launched? Show all work in the space provided.
Answer:
e. It will take 11 seconds to reach the maximum height of 1,936 feet.
f. It will take 22 seconds to return to the earth.
Step-by-step explanation:
Given:
Initial velocity [tex]v_0[/tex] = 352 ft/sec
Solving for question e.
To find the time required to reach the maximum height we will use the formula,
[tex]h(t) = -16t^2+v_0t+h_0[/tex],
where [tex]v_0[/tex] is the starting velocity
[tex]h_0[/tex] is the initial height.
Using the velocity and starting height from our problem we have,
[tex]h(t) = -16t^2+352t+0[/tex],
The path of this rocket will be a downward facing parabola, so there will be a maximum.
This maximum will be at the vertex of the graph.
To find the vertex we start out with [tex]x= \frac{-b}{2a}[/tex] which in our case is,
[tex]x=\frac{-352}{2(-16)}=\frac{-352}{-32}= 11[/tex]
So, It will take 11 seconds for the rocket to reach its maximum height.
We will find maximum height using the formula by substituting value of t we get,
[tex]h(11)=-16(11^2)+352(11)+0\\h(11) = -16 \times121+ 352 \times 11 = -1936+3872= 1936 \ ft[/tex]
Hence the maximum height will be [tex] 1936 \ ft[/tex]
Now Solving for question f.
To find the time required for rocket to reach earth.
We will set our formula to 0 to find the time.
[tex]0= -16t^2+352t+0\\-16t(t-22)=0[/tex]
Using the zero product property, we know that either -16t = 0 or t - 22 = 0. When -16t = 0 is at t = 0, when the rocket is launched. t - 22 = 0 gives us an answer of t = 22.
So the rocket reaches the Earth again at 22 seconds.

The lengths of the triangle's sides are 5, 12, and 13. What is the measure of the angle opposite to side 13?
Answer:
90°
Step-by-step explanation:
5, 12 and 13 are the sides of a right triangle ( Pythagorean triple )
13 is the measure of the hypotenuse whose opposite angle is 90°
Answer:
90°
Step-by-step explanation:
5^2+ 12^2 = 13^2
25 + 144 = 169
The Converse Pythagorean Theorem (Egyptian triangle) states that if the length of the sides of a triangle, say a, b, and c, satisfy a^2 + b^2 = c^2, then this is a right triangle with a right angle opposite to side c.
And since 5^2 + 12^2 = 13^2 satisfies the statement a^2 + b^2 = c^2, c (which is 13) is opposite to a 90° angle.

[tex]a_{1} = 0[/tex]
If we require second term put n = 2
[tex]a_{2} = a_{1} + (2-1)[/tex]
[tex]a_{2} = 0 + 1[/tex]
[tex]a_{2} = 1[/tex]
If we require third term put n = 3
[tex]a_{3} = a_{1} + (3-1)[/tex]
[tex]a_{3} = 0 + 2[/tex]
[tex]a_{3} = 2[/tex]
and so on.......
The class average on test 1 was 84. The class average on test 2 was 8 points lower. What was the class average on test 2?
The class average on test 2 is 76 points
Solution:Given that, the class average on test 1 was 84.
And the class average on test 2 was 8 points lower.
We have to find what was the class average on test 2?
Now, according to the given information.
Class average on test 2 is 8 points lower than class average on test 1.
So, class average on test 2 = class average on test 1 – 8 points
Class average = 84 – 8
Class average = 76 points.
Hence, the class average on test 2 is 76 points
