The kinetic energy K (in joules) of a falling apple is represented by K=v squared divided by 2 where v is the speed of the apple (in meters per second). How fast is the apple traveling when the kinetic energy is 32 joules?
Answers
energy (k)=32
so
32=(1/2)v^2
(I'm pretty sure it is K=(1/2)mv^2, but ok)
times 2 both sides
64=v^2
sqrt both sides
8=v
8m/s is velocity
Answer:
8 meters per second
Step-by-step explanation:
Hi, to answer this question we simply have to substitute k=32 in the formula given and solve for v.
K= (v ^ 2) /2
Substituting K=32
32 = (v ^ 2) /2
Solving for v:
32x2= v ^ 2
64 =v ^ 2
√64 =v
8 =v
v= 8 meters per second
When the kinetic energy is 32 joules, the apple is traveling at a speed of 8 m/s.

David and Ryan go to the movie theater and purchase refreshments for their friends. David spends a total of $24.75 on 3 bags of popcorn and 5 drinks. Ryan spends a total of $33.00 on 9 bags of popcorn and 4 drinks. Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Using these equations, determine and state the price of a drink, to the nearest cent.
Answers
Final answer:
To find the price of one drink, we create a system of equations based on the purchases at the movie theater and solve it using the elimination method. The calculated price of one drink is $3.75, to the nearest cent.
Explanation:
David and Ryan's purchases at the movie theater can be represented by the following system of equations to find the price of one bag of popcorn (p) and one drink (d):
3p + 5d = 24.75
9p + 4d = 33.00
We'll solve this system using the substitution or elimination method. For this example, we will use the elimination method.
Multiply the first equation by 9 and the second by 3 to equalize the coefficients for p:
(3p + 5d) × 9 → 27p + 45d = 222.75
(9p + 4d) × 3 → 27p + 12d = 99.00
Subtract the second equation from the first:
27p + 45d - (27p + 12d) = 222.75 - 99.00
33d = 123.75
Divide by 33 to find the price of one drink:
d = 123.75 / 33
d = 3.75
So, the price of one drink is $3.75, to the nearest cent.
It took Jen, who biked at a speed of 12 mph, 20 minutes to get home. What is Jim’s speed, if it took him only 15 minutes to bike that distance?
Answers
v = 12 mph
t = 20 minutes = 20/60 = 1/3 of an hour
d = r * t
d = 12 * 1/3 = 4 miles.
And put that distance into Jim's time
d = 4 miles
r = ???
t = 15 minutes = 15/60 = 1/4 hour
r = d/t
r = 4/0.25 = 16 mph. I wish I could bike that quickly.
There is another way to do it more directly. The distance is the same for both of them.
r*t = R*T
R Jim's speed and r is jen's speed.
12 * 1/3 = R * 1/4 Multiply both sides by 4
12 * 1/3 * 4 = R Cancel 12 and 1/3
R = 16.
Answer:
16 mph

Socks cost $5 per pair. The expression 5p represents the cost in dollars of p pairs of socks. Why must p be a whole number?
Answers
Since 5 is a whole number and p is a whole number, therefore, 5p must be a whole number.
Answer:
Step-by-step explanation:
p must be a whole number because $5 which is the cost of socks per pair is a perfect divisor of the expression 5p.
i.e 5p/5 = p
And in the expression p represent number of pairs

The base of a parallelogram is 10 inches the height is 2 inches more than half the base find the area
Answers
Given is a parallelogram whose base is b = 10 inches and it says height is 2 more than half-value of base i.e. h = 2 + (b ÷ 2).
So height is h = 2 + (10 ÷ 2) = 2 + 5
⇒ h = 7 inches.
We know the formula for area of parallelogram is given as follows :-
Area of parallelogram = base x height
Area of parallelogram = 10 inches x 7 inches
Area of parallelogram = 70 squared inches.
Hence, the final answer is 70 squared inches.
Final answer:
To get the area of the parallelogram, first determine the height, which is 5 inches plus 2 inches, totaling 7 inches. Using the formula (base × height), the area is calculated as 10 inches times 7 inches, resulting in 70 square inches.
Explanation:
To find the area of the parallelogram, we need to identify its base and height. The base is already given as 10 inches. Next, we calculate the height, which the problem states as '2 inches more than half the base.' First, we find half of the base: 10 inches / 2 = 5 inches. Then, add 2 inches to get the height: 5 inches + 2 inches = 7 inches. Now we have the height of the parallelogram.
Using the formula for the area of a parallelogram (base × height), we can now calculate the area.
Area = 10 inches × 7 inches = 70 square inches.
Thus, the area of the parallelogram is 70 square inches.
in the right triangle what is the value of pq
Answers
In this Pythagorean theorem question, The value of pq in the right triangle is 8 cm. Therefore, the correct answer is option C.
The given triangle is a right triangle, with two sides measuring 17 cm and 15 cm. The side opposite the right angle (perpendicular) is represented by the variable pq.
To find the value of pq, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. So, applying the Pythagorean theorem:
a2 + b2 = c2
(15 cm)2 + pq2 = (17 cm)2
225 cm2 + pq2 = 289 cm2
pq2 = 289 cm2 - 225 cm2
pq2 = 64
pq = √64
pq = 8 cm

Which best describes the number of bags of balloons she can buy?
A.She can buy from 0 to 12 bags, but no more.
B.She can buy from 0 to 20 bags, but no more.
C.She must buy 12 or more bags.
D.She must buy 20 or more bags.
Answers
A
Answer:
Option A is the correct choice.
Step-by-step explanation:
We have been given that Ling must spend no more than $40.00 on decorations for a party. She has spent $10.00 on streamers and wants to buy bags of balloons as well. Each bag of balloons costs $2.50.
The inequality [tex]10+2.5x\leq 40[/tex] represents x, the number of bags she can buy given the spending limit and how much she has already spent on streamers.
Let us solve for x by subtracting 10 from both sides of our inequality.
[tex]10-10+2.5x\leq 40-10[/tex]
[tex]2.5x\leq 30[/tex]
Now we will divide both sides of our inequality by 2.5.
[tex]\frac{2.5x}{2.5}\leq \frac{30}{2.5}[/tex]
[tex]x\leq 12[/tex]
Therefore, Ling can buy from 0 to 12 bags, but no more and option A is the correct choice.

A car maintains a speed of 23 mi/h for 5 seconds. It then accelerates to a speed of 46 mi/h in 5 seconds. It maintains that speed for the next 5 seconds. Which graph shows the car’s speed over time?
Solution:
The graph is Time versus Speed.
In figure (a), the graph has a speed or y-axis=23mi/h for time or x-axis=5seconds.
The car maintains a speed of 23mi/h for 5 seconds.
For next 5 seconds, in figure a the graph increases linearly or we have a acceleration and reaches to 46mi/h.
It accelerates to a speed of 46 mi/h in 5 seconds.
It maintains that speed for the next 5 seconds. In figure (a), after we reach speed=46mi/h, there is a straight line for 5 seconds at speed=46mi/h.

Jeremy has saved $440 from his summer job. He plans to set aside $55 each week for his expenses. Several weeks later he has $110 left.How many weeks have passed?
Answers
To find out how many weeks have passed, we subtract the remaining amount from the initial amount, and then divide by the amount saved each week. In this case, 6 weeks have passed.
Explanation:To find out how many weeks have passed, we need to subtract the remaining amount from the initial amount, and then divide by the amount saved each week.
Initial amount saved = $440
Amount saved each week = $55
Remaining amount = $110
Weeks passed = (Initial amount saved - Remaining amount) / Amount saved each week
= ($440 - $110) / $55
= $330 / $55
= 6 weeks
Therefore, 6 weeks have passed.

What is the effect if two parallel lines are rotated 90° clockwise? A)change'direction but remain parallel
B) change direction but are now perpendicular
C) no longer parallel because one line changed direction
D)no longer parallel because two lines changed direction (NEED HELP)
Answers
This is because they both rotate 90°, and they still are parallel because they were like they were before but turned sideways.
Option: A is the correct answer.
A) change direction but remain parallel.
Step-by-step explanation:We know that when same rigid transformation is applied to two lines which are parallel to each other ,then after rigid transformation they will behave the same i.e. same relationship hold between the two the only difference will be in their location.
Hence, when the both the parallel lines are rotated 90° clockwise then the direction of the line will change but they will remain parallel.The expression 3/4×1/2 represents a fraction of a circle that is shaded. Which diagram shows the correct shading?

Jim has a quarter and Jane has a number cube. In two or more complete sentences, explain why Jim is just as likely to get a head as Jane is to get an even number.
Answers
Jim is just as likely to get a head as Jane is to get an even number since the chance or probability of getting a head for Jim and getting a even number for Jane are equal i.e. 1/2=0.5
Step-by-step explanation:In a quarter there are just two outcomes-- Head and Tail
The probability of getting a head is: 1/2
Similarly in a number cube that has six possible outcomes i.e. {1,2,3,4,5,6}
The number of outcomes that represents a even number are: 3
(Since outcomes are: 2,4 and 6)
Hence, the probability of getting a even number is: 3/6=1/2
Hence, we see that the probability of getting a head and a even number is same.
