What does y equal?

0.6

Answers

Answer: 1.4

Step-by-step explanation: First, swap the sides of the equation so that the one with the variable can be in front.

So, its 2y=2.8

To solve this, you simply divide both sides of the equation by 2.

2 divided by 2 is 0. That leaves you with the y by itself. Then, 2.8 divided by 2 is 1.4

So, y=1.4

\text {The First Step is to Flip the Equation:}

\text {Before: 2.8=2y}\n\text {After: 2y=2.8}

\text {Your Final Step is to Divide by 2:}

\text {2y/2=2.8/2}

\fbox {y=1.4}

What is 800 divided by 8?

Answers

The division of 800 divided by 8 using long division gives the quotient  100.

When dividing 800 by 8, perform long division as follows:

                              100

                             -------

                         8 | 800

                              800

                             -------

                                0

The division is evenly divisible, and the quotient is 100.

Therefore, 800 divided by 8 is equal to 100.

800/8 = 100/1 x 8/8
So 100/1 or 100 is the answer :)

Colby and Jaquan are growing bacteria in an experiment in a laboratory. Colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. Jaquan has a different type of bacteria that doubles every 3 hours. How many bacteria should Jaquan start with so that they have the same amount at the end of the day?

Answers

Here's the general formula for bacteria growth/decay problems

Af = Ai (e^kt)

where: 
Af = Final amount
Ai = Initial amount
k = growth rate constant
t = time

But there's another formula for a doubling problem.
kt = ln(2)

So, Colby (1)
k1A = ln(2) / t
k1A = ln(2) / 2 = 0.34657 per hour.

So, Jaquan (2)
k2A = ln(2) / t
k2A = ln(2) /3 = 0.23105 per hour.

We need to use the rate of Colby and Jaquan in order to get the final amount in 1 day or 24 hours.

Af1 = 50(e^0.34657(24))
Af1 = 204,800

Af2 = 204,800 = Ai2(e^0.23105(24))
Af2 = 800

Bicycle rental on the seawall at the beach cost a mandatory minimum of $5 for the first hour and then $4 for each additional hour. When three or more bikes are rented together, the owner gives a 20% discount on the additional hours. If Marty and his family rent four bicycles, identify the expression which represents the cost.A) 12.8x + 20x
B) 12.8x + 20
C) 12.8x + 16x
D) 32.80x

Answers

Answer:  The correct option is (B) 12.8x+20.

Step-by-step explanation:  Let, 'x' be the number of hours for which the bicycle is rented except the first hour.

Then, according to the given information, the cost of renting 1 bicycle is given by

c=4x+5.

There is a discount of 20% on additional hours 'x' when three or more bikes are rented together.

Since Marty and his family rent four bicycles, so the discount on additional hours for 1 bicycle is given by

D=20\%* 4x=(20)/(100)* 4x=(4)/(5)x.

Therefore, the total cost of renting 4 bicycles is given by

C=4\left(5+(4x-(4)/(5)x)\right)=4\left(4+3.2x\right)=12.8x+20.

Thus, the required expression for the cost is 12.8x+20.

Option (B) is correct.

Cost = fix cost + hourly cost - discount

Cost = 4* [5 + 4x - 4x(20/100)] = 4*[5 + 4x - 0.8x] = 4*[5 + 3.2x] = 20 + 12.8x

Answer: option B) 12.8x + 20
