A hot air ballon went from an elevation of 6,669 feet to an elevation of 3,402 in 54 minutes. What was its rate of descent?
Answer:
elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!

9. Fred bought 24 new baseball cards for $50. There were two types of cards. One type cost $1 per card, and the other cost $3per card. Define the variables, and write a system of equations to find the number of each type of card he bought. Then solve the system using the best method for the situation.
Answer:1$ cards = 11 cards 3$ cards= 13
Step-by-step explanation:the first equation is -x-y=-24 and the second is x+3y=50. Solving them as a system will get 2y=26 to y=13 then plug in 13 to the y for -x-y=-24 to get 11. Mr jacobs is hard I know lol. Use elimination by subtraction and keep the first equation as x+y=24 and then flip to negative

Answer:
a = w/p
Step-by-step explanation:
To take a out of the fraction, we can multiply both sides by a to get ap = w. Now, we divide both sides by p to get a = w/p.
Answer:
a = w/p
Explanation:
Step 1: Multiply both sides by a.
ap = w
Step 2: Divide both sides by p.
ap/p = w/p
a = w/p

Dawn has been using two bank accounts to save money for a car. The difference between account 1 and account 2 is $100. If she uses 3/8 of account 1 and 7/8 of account 2, Dawn will have a down payment of $2,000. Solve the system of equations to find the total amount of money Dawn has in each account.
A – B = 100
Three-eighthsA + Seven-eighthsB = 2,000
Dawn has $
in account 1 and $
in account 2.
Answer:
dawn has $ 1,670 in account 1 and $ 1,570 in account 2
Step-by-step explanation:
Answer:
1,670 in account 1 ; 1,570 account 2
Step-by-step explanation:
1x - 1y = 100 X=7 7x-7y= 700
3/8x + 7/8y= 2000 X=8 3x+7y= 16000
10x = 16700
The black graph is the graph of y=f(x). Choose the equation for the red graph.
Answer:
y-1 = f(x)
Step-by-step explanation:
Here, we want to choose the equation for the ref graph
The red graph as we can see is above the black
This means it is more positive
The difference between the two is just 1 unit
By the addition of 1 to the y-value of the black graph, we get the red
Thus, we have that;
y- 1 = f(x)

Use the Law of Logarithm to expand the expression. ln(y √x/z (I know the answer is 2ln(y)+ln(x)-ln(z) all over 2, but I need the steps to get there)
Answer:
[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]
Step-by-step explanation:
From the question we are told that the expression [tex]ln(y √x/z[/tex]
[tex]in (y\sqrt{\frac{x}{y}})[/tex]
[tex]in(y)+in(y\sqrt{\frac{x}{y}})[/tex]
[tex]in(xy)=in(x)+in(y)[/tex]
[tex]in(xy)=in\frac{x}{z} ^1^/^2 +in(y)[/tex]
[tex]in(xy)=\frac{1}{2} in(\frac{x}{z}) +in(y)[/tex]
[tex]in(xy)=\frac{1}{2} in(x)-in(z) +in(y)[/tex]

So, I need to find out, how long one of the side lengths of the orange square is. the square is in the semicircle. you do not have any numbers given, and should use just letters.
thanks in Advance
Answer:
Assuming the square and the semicircle aren't merged somehow, and we need to calculate their full area, we should take into account:
Area of a square:
(Side length)² = 22² = 484 square inches
Area of a circle with a diameter of 22inch:
3'14 · (radius)² = 3'14 · 11² = 379'94 square inches
Since we have half a circle, the total areas to add will be:
1/2 · 379'94 + 484 = 673'97

b. When does the diver hit the water
c. At what time on the diver's descent toward the water is the diver again at the same height as the springboard?
d. When does the diver reach the peak of the dive?
Answer:
brainliest please i work really hard for this
Step-by-step explanation:
Hit Water:
He hits the water when his height, h(t), is 0 meters above water.
0 =
This is no factorable so we use the quadratic formula.
(-b±√(b²-4ac))/2a
(-10±√(10²-4*-5*3))/2*-5
(-10±√(100+60))/-10
(-10±√160)/-10
(-10±√16*10)/-10
(-10±4√10)/-10
(-10±4√10)/-10 Seperate to two equations
(-10+ 4√10)/-10 and (-10- 4√10)/-10
(-10+12.65)/-10 (-10-12.65)/-10
-.265 Not Solution 2.265 Seconds
Becasue there is no negative time
The diver hits the water at 2.265 seconds
For when he is at the same height as the spring board, we need to find the height of the spring board, and we do that by substituting 0 for t because we need the height 0 seconds after he jumps.
h(0) = -5*0^2 +10*0 +3
h(0) = 3 The height of the spring board is 3 so we need to know when he is at 3 meters again.
3= -5t^2 + 10t + 3 Subtract 3 from both sides
0= -5t^2 +10t
0= -5(t^2-2t) Factor out -5 and divide both sides by -5
0= t^2-2t
0= t(t-2) Factor out t.
Solve.
t= 0 t-2=0
t= 2
He will be at the same height as the spring board at t= 2 seconds
There is a spinner with 10 equal areas, numbered 1 through 10. If the spinner
is spun one time, what is the probability that the result is a multiple of 2 and a
multiple of 5?
Answer:
10%
Step-by-step explanation:
The multiples of 2 are 2,4,6,8,10, and so on
The multiples of 5 are 5, 10, 15, 20 , 25, and so on
It is evident that the only one that matches up between 1-10 is 10.
There are 10 options, and our chances are random. There is only 1 option for it to be a multiple of both 2 and 5. Therefore, the probability is 1/10, or 10%
