Answer:
[tex]Halfway = 37.5[/tex] --- above the sea level
Step-by-step explanation:
Given
[tex]Top = 127ft[/tex] --- above sea level
[tex]Valley\ Floor = 52ft[/tex] --- below sea level
Required
Determine the elevation at half way
To do this, we simply add the elevations of the top of the hill and the valley floor.
Then calculate the average by dividing the sum by 2
[tex]Total = Top + Valley\ Floor[/tex]
[tex]Total = 127 + (-52)[/tex]
Note that the negative sign represents below sea level
[tex]Total = 127 -52[/tex]
[tex]Total = 75[/tex]
At half way, the elevation is:
[tex]Halfway = \frac{1}{2} * Total[/tex]
[tex]Halfway = \frac{1}{2} * 75[/tex]
[tex]Halfway = 37.5[/tex] --- above the sea level

Noel works as a driver for a transportation company. On average, he drives 152 hours to make 19 successful deliveries. Assume this rate is his
constant rate for delivering goods. If you graph this relationship with time along the x-axis and number of deliveries along the y-axis, the slope of
the line you get gives Noel's unit rate for a successful delivery. Which unit rate can be interpreted as the slope?
So I have this test too and I'm pretty sure it's 8. I will check back when I know for sure and have my answer submitted.
Edit:
Yes the answer I originally gave is correct.
Noel's unit rate for successful delivery is 1/8 of a delivery per hour option (D) is correct.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
The missing options are:
A. 8 deliveries per hour
B. 2/17 of an hour per delivery
C. 1/8 of a delivery per hour
D. 1/8 of an hour per delivery
We have:
On average, he drives 152 hours to make 19 successful deliveries.
The rate is constant.
The total time for which Noel drives = 152 hours
The total number of successful deliveries = 19
Noel's unit rate for a successful delivery
= total successful deliveries/total hours
= 19/152
Divide by 8 on the numerator and denominator:
= 1/8
y = (1/8)x
Here x represents time
y represents the number of deliveries
Thus, Noel's unit rate for a successful delivery is 1/8 of a delivery per hour option (D) is correct.

Alexis had 98 trading cards last Saturday.
(o
She gave a dozen to her little brother but her big brother gave her a pair.
Alexis traded 9 more cards for 4 new ones that were more valuable.
She then traded another half dozen for 1 that she had been hoping to find.
Alexis wants to get a card album for her birthday so she can organize all her cards.
Yesterday she was running home with all of her cards in her bag. She dropped two of her
cards along the way because the bag was not zipped.
How many cards did she have when she got home?
What is the first thing that you would do to solve this problem?

5. 24 points scored in 4 games; a points scored in 10 games
Complete Question:
24 points scored in 4 games; a points scored in 10 games. Are they equivalent?
Answer:
Both games are not equivalent
Step-by-step explanation:
Given
[tex]24\ points = 4\ games[/tex]
[tex]1\ point = 10\ games[/tex]
Required
Determine if they are equivalent
We have that:
[tex]24\ points = 4\ games[/tex] ----- (1)
[tex]1\ point = 10\ games[/tex] ----- (2)
To solve this, we simply make the number of games equal.
Multiply (1) by 2.5
[tex]2.5 * 24\ points = 4\ games * 2.5[/tex]
[tex]60\ points = 10\ games[/tex]
This implies that there are 60 points in 10 games
While for (2):
[tex]1\ point = 10\ games[/tex] means that
There are 1 point in 10 games
Hence, both games are not equivalent
Because, the number of points differ in the same number of games
Help !! (x + 2y = 6.)
Answer:
what do you exactly want me to do? rewrite the equation or solve it?
Step-by-step explanation:
Answer:
x=−2y+6
y=−12x+3
Step-by-step explanation:
Let's solve for x.
x+2y=6
Step 1: Add -2y to both sides.
x+2y+−2y=6+−2y
x=−2y+6
Let's solve for y.
x+2y=6
Step 1: Add -x to both sides.
x+2y+−x=6+−x
2y=−x+6
Step 2: Divide both sides by 2.
2y/2=−x+6/2
y=−12x+3

College roommates John and David were driving home to the same town for the holidays. John drove 55mph, and David, who left an hour later, drove 60mph. How long will it take for David to catch up to John?
Answer:
sorry
Step-by-step explanation:
It will take for David 11 hours to catch up with John
Speed is the ratio of distance traveled to the total time taken. Speed is given by:
Speed = distance / time
Let d represent the distance at which both John and David meet up at time t hour.
Since drove at 55 mph and is an hour faster, hence:
55 = d / (t + 1)
d = 55t + 55 (1)
John is driving at 60 mph, hence:
60 = d / t
d = 60t (2)
equating equation 1 and 2:
55t + 55 = 60t
5t = 55
t = 11 hours
Hence, it will take for David 11 hours to catch up with John

A doctor prescribe 125 miligrams of a therapeutic drug that decays by about 10% each hour. Write an exponentia lmodel representing the amount A in milligrams of the drug remainng in the patient's system after t hours.
Answer:
[tex]C(t)=125\cdot 0.9^t[/tex]
Step-by-step explanation:
Exponential Decay Function
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The doctor prescribed 125 milligrams of a therapeutic drug. It decays by 10% each hour. The initial value is Co=125 and the decay rate is r=0.1 per hour. Substituting into the function:
[tex]C(t)=125\cdot(1-0.1)^t[/tex]
Operating:
[tex]\mathbf{C(t)=125\cdot 0.9^t}[/tex]
Where t is expressed in hours.

b. A rhombus is a parallelogram.
c. A parallelogram is a square.
d. A rectangle is a square.
Answer:
A and B
Step-by-step explanation:
Here, we want to select the statements that are sometimes true
The correct answers are that;
1. A parallelogram has congruent diagonals
This is in the case of a rectangle
Whenever we have the diagonals of a parallelogram equal, then what we have is a rhombus
b. A rhombus is a parallelogram
In this case, we have that a rhombus is a kind of parallelogram with all four sides equal and the diagonal meet at 90 degrees
An experiment consists of dealing 6 cards from a standard 52-card deck. What is the probability of being dealt 6 hearts?
Answer: 0.0000842890
Step-by-step explanation:
Given that :
Number of cards in a deck = 52
Number of hearts in a deck = 13
Probability of being dealt 6 hearts :
Probability = (required outcome / Total possible outcomes)
Required outcome = choosing 6 hearts from a possible 13
13C6:
Recall : nCr = (n! / (n-r)!r!)
13C6 = 13! / (13-6)!6!
13C6 = 13! / 7!6!
13C6 = (13*12*11*10*9*8)/(6*5*4*3*2*1)
13C6 = 1235520 / 730
13C6 = 1716
Total possible outcomes :
52C6 = 52! / (52-6)!6!
52C6 = 52! / 46!6!
52C6 = (52*51*50*49*48*47)/(6*5*4*3*2*1)
52C6 = 14658134400 / 720
52C6 = 20358520
Hence,
P(6 hearts) = 1716 / 20358520
P(6 hearts) = 0.0000842890
