Answer:
The net change is a decrease of 1,280 feet
Step-by-step explanation:
From the question, we understand that the hiking team has a work rate of 320 feet / hour
Now that are descending between the hours 1pm and 5pm, this means that they descended for a total of 4 hours.
Now the total number of feet they have descended will be the number of hours * work rate = 4 hours * 320 feet/hour = 1,280 feet
Thus, the net change is decrease of 1,280 feet
It took Beth 16 minutes to read 8 pages of a book. If she reads at a constant rate, how long did it take Beth to read 5 pages?
Answer:
Step-by-step explanation:
10 minutes
if it took her 16 minutes to read 8 pages then that means it takes her 2 minutes to read one page. 2 times 5 is 10
Answer:
Step-by-step explanation:
It would be ten. Because it took her 16 minutes to read 8 pages and 8 pages times 2 minutes each page = 16 minutes, so 5 pages times 2 minutes each page = 10

You are jumping off the 12-foot diving board at the municipal pool. You bounce up at 6 feet per second and drop to the water. Your height (h) in feet above the water in terms of (t) seconds is given by h = -16t^2 + 6t + 12. What is the first step in determining the maximum height that you reach during your dive?
Answer:
h_max = 12.56 units
(the exercise does no specify the units)
Step-by-step explanation:
You have the following function:
[tex]h(t)=-16t^2+6t+12[/tex] (1)
To calculate the maximum height reach by you, you first derivative the function h(t) respect to t:
[tex]\frac{dh(t)}{dt}=-32t+6[/tex]
Next, you equal the result of the derivative to zero and you obtain t:
[tex]-32t+6=0\\\\t=\frac{6}{32}=\frac{3}{16}[/tex]
Then, you replace this value of t in the equation (1) and you obtain the maximum height:
[tex]h(t)=-16(\frac{3}{16})^2+6(\frac{3}{16})+12[/tex]
[tex]h(t)=12.56[/tex]
hence, the maximum height is 12.56 units

On the first day of school, each student is given $0.50 to attend. On day two, each student earns $1.00, day 3, $2.00, etc. How much do
students earn on the ninth day of school?
Answer:
$128
Step-by-step explanation:
We can model this as an exponencial function, as the value earned each day doubles:
P = Po * r^t
Where P is the value after t days, Po is the inicial value and r is the rate.
In this case, we have r = 2 and Po = 0.25 (so for t=1 we will have P = 0.5).
The equation will be:
P = 0.25 * 2^t
Then, for t = 9, we have:
P = 0.25 * 2^9 = $128
how many ways can you arrange SONG
Song= sngo, sogn, gnso, gosn, gnos, snog, 6 ways ?
===========================================================
Explanation:
We have four blank slots to fill. Call them slot A,B,C,D. There are 4 letters to pick from when filling slot A. After that selection is made, there are 3 letters left for slot B. This process keeps going til you count down to 1.
Multiplying those values out gives 4*3*2*1 = 24
-----------
Extra info:
This concept is given factorial notation of an exclamation mark, so you'd write 4! = 4*3*2*1 = 24 or simply 4! = 24.
Another example of factorial notation is 7! = 7*6*5*4*3*2*1. We start with 7 and count our way down til we get to 1, multiplying all along the way.
You could also use the nPr permutation formula [tex]_nP_r = \frac{n!}{(n-r)!}[/tex] though that isn't necessary in my opinion since it involves factorials which we already used above. If you use the permutation formula, then you would have n = 4 and r = 4. The n refers to the number of items you are arranging and r = 4 is the number of slots you are filling.
It turns out that [tex]_nP_r = \frac{n!}{(n-r)!} = n![/tex] when r = n.
You can think of it in a smaller chunk. If we fix S to be the first letter, then we have O,N,G to rearrange. There are 6 ways to do this as shown
ONGOGNNOGNGOGONGNOBasically showing that 3! = 6. We have 4 different ways to have the first letter be selected, so we have 4*6 = 24 permutations of SONG.

At science camp the kitchen served half of there blueberries with breakfast after dinner they put the remaining 5270 g of berries on top of their ice cream desert how many kilogram of blueberries did the science camp start with?
Answer:
10.54 kg
Step-by-step explanation:
Here, we are interested in calculating the amount in kilograms of blueberries the science camp started with.
Now let’s take a look at the question once again;
after serving half of the blueberries with breakfast, the amount of berries remaining is 5270 g
What this means is that 1/2 of the berries correspond to 5270 g and the other half too will be 5270 g
Thus, the total will be 5270g + 5270g = 10,540 g
Now the question asks us to calculate our answer in kilograms.
Mathematically, 1000g = 1kg
Thus 10,540 g = xkg
Thus x = (10 540 * 1)/1000 = 10.54 kg

A standard deck of playing cards has 13 cards in each of four suits: hearts, clubs, diamonds, and spades. Two cards are chosen from the deck at random. What is the probability of choosing one club and one spade, without replacement?
A. 25/102
B.13/102
C.13/204
D.1/2
There are 52 cards in the deck.
Picking a spade would be 13/52 which reduces to 1/4
After the first card is picked there are 51 cards left, picking a club would be 13/51
Picking both would be 1/4 x 13/51 = 13/204

Find the circumferences of the two circles. Circle A has a radius of 21 meters and Circle B has a radius of 28 meters. Use pencil and paper. Is the relationship between the radius of a circle and the distance around the circle the same for all circles? Explain.
Answer:
1.) Circumference of circle A = 131.95 metre
2.) Circumference of circle B = 175.93 metre
3.) Yes. Radius is proportional to the circumference.
Step-by-step explanation: Given that Circle A has a radius of 21 meters and Circle B has a radius of 28 meters
Circumference of a circle = 2πr
For circle A
Radius r = 21
Circumference = 2 × 3.143 × 21
Circumference = 131.95 metre
For circle B
Circumference = 2 × 3.143 × 28
Circumference = 175.93 metre
Is the relationship between the radius of a circle and the distance around the circle the same for all circles? YES
Because the radius of the circle is proportional to the distance around them ( circumference ) for all the circle. That is, the larger the radius, the larger the circumference

Answer:
192[tex]feet^3[/tex]
Step-by-step explanation:
The formula for the area of a rectangle is : [tex]length*width[/tex]
In order to work out the volume you would first need to work out the area. You can do this by multiplying the length of 6 by the height of 4, this gives you 24.
To workout the volume you would need to multiply the area of 24 by the width of 8, this gives you 192.
1) Multiply 6 by 4.

An amusement park has two types of season passes. Plan 1 charges a one-time fee of $170.00 for admission plus $8.00 every trip for parking. Plan 2 charges a one-time fee of $93.00 for parking plus $15.00 every trip for admission. For what number of trips is the cost of these plans the same?
Answer:
Plan1:
y = 170 + 8x
Plan2:
y = 93 + 15x
170 + 8x = 93 + 15x
7x = 77
x = 11 Trips
Step-by-step explanation:
The number of trips when the cost of plan 1 and plan 2 would cost the same amount of money is 11 trips.
When the plans cost the same amount of money?The equation that reprepsents the total cost of both plans is:
Total cost = one time fee + (cost of parking x number of trips)
Plan 1 : 170 + 8t
Plan 2: 93 + 15t
When both plans cost the same, the two above equations would be equal.
170 + 8t = 93 + 15t
In order to determine the value of t, take the following steps:
Combine similar terms
170 - 93 = 15t - 8t
Add similar terms
77 = 7t
Divide both sides by 7
t = 77/7
t = 11 trips
