7/6 divided by 8 write in simplest form
Answer: the answer is 7/48
Step-by-step explanation:
The simplest form of the division is 7/48.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b = a[/tex] divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
We have to write in simplest form
7/6 divided by 8
[tex]7/6 \div 8 \\\\= \dfrac{7}{6} \times \dfrac{1}{8}\\\\= \dfrac{7}{48}[/tex]

2.3×10⁹=(1×10³)(2.3×10^n)
Answer:
n = 6
Step-by-step explanation:
2.3 × [tex]10^{9}[/tex] = (1 × 10³)(2.3 × [tex]10^{n}[/tex] )
(1 × 10³)(2.3 × [tex]10^{n}[/tex] ) = (1)(2.3) × (10³)( [tex]10^{n}[/tex] ) = 2.3 × [tex]10^{3+n}[/tex]
2.3 × [tex]10^{3+n}[/tex] = 2.3 × [tex]10^{9}[/tex] ⇒ 3 + n = 9 ⇒ n = 6

At time t=0 hours, a tank contains 3000 litres of water. Water leaks from the tank. At the end of every hour there is x% less water in the tank than at the start of the hour. The volume of water, in litres, in the tank at time t hours is Vt. Given that Vt=KtV0 V2=2881.2 work out the value of k and the value of x.
Answer:
x = 2; K = 0.98
Step-by-step explanation:
At time, t = 0, Volume of Water = 3,000 litres
After t hours , the Volume of water in the tank = Vt
At the end of every hour there is a x% less water in the tank then at the start of the hour
After 1 hour, volume of water left Vt = V1
V1 = 3,000 - 3000 × (x/100)
V1 = 3,000 - 30x
After 2 hours, Volume of water left is V2
V2 = (3,000 - 30 x) - (3,000 - 30 x) × (x/100)
V2 = (3,000 - 30 x) - (3000x - 30x²)/100
V2 = {100(3000 - 30x) - x(3000 - 30x)} /100
V2 = {(3000 - 30x)(100 - x)}/100
Recall, V2 = 2881.2
Therefore
{(3000 - 30x)(100 - x)}/100 = 2881.2
(3000 - 30x)(100 - x) = 288120
300000 - 3000 x - 3000 x + 30 x² = 288120
30 x ² - 6000 x + 11880 = 0
Dividing both sides by 30
x² - 200 x + 396=0
Factorizing:
(x -198)(x-2) = 0
x = 198 or x = 2
Since the percentage by which the water reduces cannot be greater than 100, x = 2 is chosen.
Step 2: Solving for k
Given that Vt=KtV0
K = Vt/V0
At t = 1
V1 = 3000 - 30x
V1 = 3000 - 30 × 2
V1 = 3000 - 60
V1 = 2940
K = 2940/3000
K = 0.98

The density of a material 4 kg/cup on converting it into pounds per liter will be 37.2 lbs/lt.
What are derived units?
Defining a derived unit is the process of deriving a measurement unit from one or more of the seven base units of the International System of Units (SI). There are two types of derived units: dimensionless and the product of base units.
Here it is given that, the density d of a certain material is 4 kilograms per cup of volume and it is find the density of material in pounds per liter.
Now it is known that,
1 kg equals 2.2 pounds
and, 1 cup of volume equals 0.237 lt.
converting the density d of material in pounds per liter and Rounding it to the nearest tenth :
[tex]\begin{aligned}d&= 4\:\frac{\text{kg}}{\text{cup}}\\&=\:\frac{4\cdot2.2\text{ pounds}}{0.237\:\text{lt.}}\\&\approx 37.2\:\frac{\text{ pounds}}{\:\text{lt.}}\end{aligned}[/tex]
Therefore, the density of a material 4 kg/cup on converting it into pounds per liter will be 37.2 lbs/lt.

Billy started a lawn mowing business and had to take out a $650 loan to buy all the supplies. The first month he made a profit of $600 and then the next two months he records a profit of $-75, and the last two months he made a profit each month of $150. What is the total profit of Billy’s business so far?
Answer:
25
Step-by-step explanation:
He's already out of 50 bucks, because he didn't profit enough for his loan. So now we have -50, then in the next 2 months he records a profit of -75. We add that onto -50, to make -125. Then he makes 150 in profit so that's good good job Billy, -125+150=25. I hope this is right LOL

1. During which parts of the graph does Arthur’s distance from home decrease?
2. When is Arthur waiting for bagels? Explain how you know.
3. If Arthur’s pace had not been constant after leaving the bagel shop, which part of the graph would change? Explain how that part of the graph would change.
Answer:
1. During part 2. The y-axis (line going up) represents his distance. At part 1, his distance stays the same because he is sitting in the park. At part 2 we see the line go down, which means his distance from home is decreasing.
2.At part 3. His distance stays the same, which represents him waiting in line. We know this because the line stays at the same distance and the time increases(this is the x-axis)
3. There would be another part of the graph. If he had stopped again, there would have been another straight line with the distance the same and the time increasing.
