A magazine contains 80 pages of advertisements. This represents 64% of the total pages in the magazine. How many total pages are in the magazine?
Answers
Answer:
125 pages
Step-by-step explanation:
Since 80 is 64% of unknown x we can write the equation 80/x=64/100. Now cross multiply to get 8000=64x. Divide both sides by 64 to get 125=x.

which expression can be used to find the slope of a line containing the points (-3,7) and (7,-1)
Answers
Answer:
y2- y1
x2- x1
which would be,
-1 - 7
7- (-3)
Steps:
(-3, 7) (7, -1)
(x1,y1) (x2,y2)
Answer:
slope is delta y over delta x. In other words change in y over change in x. so if you take -3 (this is x) and 7 (this is also x) and you find the change. in this example it is positive 10. now you set that number aside and work on y now. so you now take 7 (this is y) and -1 (this is also y) and you find the change. It is -8. Finaly, since slope is delta y over delta x your answer is -8/10. -8/10 is your slope.

Step-by-step explanation:
From the question, we are informed that Andrew is descending 57 feet underwater while scuba diving and that he descends at a rate of 3 feet per second.
The number of seconds that it will take Andrew to descend the full distance will be 57 divided by 3. This will be:
= 57/3

Manuel has already sold $20 worth of tickets to the school play. He has 4 tickets left to sell at $2.50 per ticket. Write a function for the total amount collected from ticket sales
Answers
Answer:
The function is C(t)=20 + $2.50X
Total amount is $30
Step-by-step explanation:
Manuel has already sold $20 worth of tickets to the school play, He has 4 tickets left to sell at $2.50 per ticket
It means he sell 1 ticket for $2.50
Then he sold the $20 worth of tickets to the school play at $2.50 per ticket i.e $20/2.50= 8 tickets which means he sold 8 tickets for $20.
If He has 4 tickets left to sell at $2.50 per ticket
Then he will sell at ($2.50×4)=$10
Then total tickets sold= $10+$20= $30
LET US WRITE THE FUNCTION NOW
The function for the total amount collected from ticket sales can be written as
C(t)=20 + $2.50X
Where X is the number of tickets to be sold
C(t) = total amount
$20= initial sold
If He has 4 tickets left to sell then
C(t)=20 + $2.50(4)
C(t)= 20+10= $30

Hannah wants to have $ 7500 to help pay for a new deck in 13 years. If she wants to put her money into an account earning 7% interest compounded continuously, how much should she invest now, so that she will have $ 7500 in 13 years?
Answers
Answer:
$ 3,018.93
Step-by-step explanation:
This question is asking us to find the Principal.
Hence, the formula for compound interest that is compounded continuously is :
A = Pe^rt
P = Principal/Initial amount
A = Amount after investment = $7500
r = Interest rate = 7% = 0.07
t = time in years = 13 years
Hence,
7500 = Pe^0.07 × 13
P = 7500/e^0.07 × 13
P = 7500/e^0.97
P = $3018.9316803
Approximately P (The amount that should be invested ) = $3,018.93

A Robotics Club has 16 members. Each member pay monthly dues of $14.60. On the first day of the month 10 members paid their dues. The remaining members paid their dues on the second day of the month. How much money was collected on the second day of the month?
Answers
Answer:
Total cash collected= $87.6
Step-by-step explanation:
Giving the following information:
A Robotics Club has 16 members. Each member pay monthly dues of $14.60. On the first day of the month 10 members paid their dues.
To calculate the total cash collected on the second day, we need to use the following formula:
Total cash collected= unitary cost*number of members
Total cash collected= 14.6*6
Total cash collected= $87.6
Adam is d years old and Brandon is b
old and Brandon is b years older than Adam.
In how many years will Brandon be twice as old as Adam is now?
Answers
Answer:
-b years from now
Step-by-step explanation:
The age of Adam = d
The age of Brandon = b
The number of years Brandon is older than Adam = b
Therefore;
b = d + b
∴ d = 0
Therefore, Brandon will be twice as old as Adam is now when Brandon is 2 × 0 = 0 years
The number of years before Brandon will be twice as old as Adam is now = 0 - b = -b years from now

Answer:
The measure of angle MNP is
m ∠ MNP = (x - y)/2
Explanation:
The image attached shows the figure corresponding to this question.
The angle MNP, which is also the angle LNP, is formed by the intersection of a secant and a tangent to a circle.
Then, you can use the theorem:
the angle formed by a secant and a tangent to a circle that intersect outside the circle is half the difference of the major arc minus the minor arc.
The major arc formed is identified with the letter x and the minor arc is identified with the letter y. Thus, the measure of the angle MNP is half the difference x - y:
m ∠ MNP = (x - y)/2
