A small companies net income for the first six months of the year was $76,500 and for the last six months it was $100,000 what is the ratio of the first six months of the year to the last six months of the year and simplest form
Answers
Answer:
The ratio of net income in the first 6 months, to the last six months is $76,500 / $100,000. This simplifies intuitively as follows:
76500/100000
Dividing by 100: 765/1000
Dividing by 5: 153/200
The denominator 200 is only divisible by the prime numbers 2 and 5, and since the numerator 153 is not divisible by either 2 or 5, this means that this is in simplest form, and the final answer is 153/200.

The equation y=15x+20 represents the cost y (in dollars) of a gym membership after x months
Answers
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The cost of a gym after 2 months is 50
The cost of a gym after 3 months is 65
The cost of a gym after 4 months is 80
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 5 is an equation.
3x + 4x = 5 is an equation.
We have,
y = 15x + 20
x denotes months
y denotes the cost for x months.
20 = one-time membership
15 = cost per month.
Now,
Substitute x = 1, 2, 3, 4, 5, 6, . . .
y = 15 x 1 + 20
y = 15 + 20
y = 35
y = 15 x 2 + 20
y = 30 + 20
y = 50
y = 15 x 3 + 20
y = 45 + 20
y = 65
y = 15 x 4 + 20
y = 60 + 20
y = 80
Thus,
The cost of a gym after 2 months is 50
The cost of a gym after 3 months is 65
The cost of a gym after 4 months is 80

Three sailors were marooned on a deserted island that was also inhabited by a band of monkeys. The sailors worked all day to collect coconuts but were too tired that night to count them, They agreed to divide them equally the next morning. During the night, one sailor woke up and decided to take his share. He found that he could make three equal piles, with one coconut left over, which he threw to the monkeys. Thereupon, he put his own share in a pile down the beach, and left the remainder in a single pile near where they all slept. Later that night, the second sailor awoke and, likewise, decided to take his share of coconuts. He also was able to make three equal piles, with one coconut left over, which he threw to the monkeys. Somewhat later, the third sailor awoke and did exactly the same thing with the remaining coconuts. In the morning, all three sailors noticed that the pile was considerably smaller, but each thought that he knew why and said nothing. When they then divided what was left of the original pile of coconuts equally, each sailor received seven and one was left over, which they threw to the monkeys. How many coconuts were in the original pile
Answers
Step-by-step explanation:
x-the initial number of coconuts
x=3y+1
2y=3z+1
2z=3×7+1=>z=11=>y=17=>x=52
The number of coconuts in originally was 25.
What is division?Division is breaking a number up into an equal number of parts.
Given that, there are three sailors and a band of monkeys on an island, and they are distributing the coconuts,
Let x be the number of coconuts to start with. We are given that it is a whole number.
After Sailor 1 gives one to the monkey and takes a third. Then the number of coconuts remaining is (x-1) - (x-1) (1/3) = 2(x-1)/3.
Sailor 2 gives 1 coconut to the monkey, so there are 2(x-1)/3 - 1 = (2x-5)/3. He takes a third and leaves [(2x-5)/3](2/3) = (4x-10)/9.
Sailor 3 gives 1 to the monkey, so now
(4x-10)/9 -1 = (4x-19)/9 are left.
He takes a third, leaving behind [(4x-19)/9](2/3) = (8x-38)/27
This is the number of coconuts in the pile that the sailors found next morning.
Let (8x-38)/27 = y, say, which gives 8x = 27y + 38.
We are given that it is less than 10, and it is a whole number divisible by 3 (because each sailor took a third and nothing was left).
Therefore, possible values for this number are 0, 3, 6 and 9. But we are also given that the initial pile had a whole number of coconuts. Hence, the problem reduces to finding that y from which 8x = 27y + 38, gives an x as a whole number.
You will see that the only y that gives x as a whole number is y = 6
Then 8x = 200, so x = 25
Hence, the number of coconuts were 25.

Erik rode down an escalator, while Raj rode up.

Erik's elevation is represented by the equation h = 12 – 0.75t, and Raj's elevation is represented by h = 0.75t. What does the point of intersection on the graph represent?
Erik and Raj were at the same elevation after both of them had been riding the escalator for 6 seconds.
Erik and Raj were at the same elevation after both of them had been riding the escalator for 8 seconds.
Erik and Raj were at the same elevation after Erik had been riding the escalator for 6 seconds and Raj had been on the escalator for 8 seconds.
Erik and Raj were at the same elevation after Erik had been riding the escalator for 8 seconds and Raj had been on the escalator for 6 seconds.
Answers
Answer:
B. They were at the same elevation after riding the escalator for 8 seconds
Step-by-step explanation:
Point of Intersection
If we solve the elevation equations of both we find that Erik and Raj were at the same elevation after both of them had been riding the escalator for 8 seconds.
What is a graph?A graph is a collection of various points on a sheet.
What does the intersection point says?If we take elevation equations of both and solve we could easily find the value of t
h=12-0.75t
h=0.75t
equating both
0.75t=12-0.75t
1.5t=12
t=8
Hence it means that they were at the same elevation after both of them had been riding the escalator for 8 seconds.
