Twice a number added to six results in thirsty

Mathematics
1 answer:
horsena [70]3 years ago

Answer: 6+2n=30

Step-by-step explanation:

Since you did not say what you need to do, I will assume that you need to write an equation.

In order to solve this exercise it is important to remember the following:

1. The word "Twice" indicates you must multiply by 2.

2. The word "result" indicates an equal sign = .

Then, based on the explained above, you know that "Twice a number" can be represented with the following expression:

2n

Where "n" is the number mentioned.

Then, you know that "Twice a number added to six" can be expressed as following:

6+2n

 Therefore, you can conclude that "Twice a number added to six results in thirsty" can be represented with the following equation:

6+2n=30

The spread of a flu virus on a college campus is modeled by y= 5000/(1+4999e^-0.8t), where y is the number of students infected
Darina [25.2K]

Answer:

537 students

11 days

Step-by-step explanation:

       5000

y=  -----------------

    (1+4999e^-0.8t)

a)  after 8 days  means t =8


       5000

y=  -----------------

    (1+4999e^-0.8*8)

       5000

y=  -----------------

    (1+4999e^-6.4)

       5000

y=  -----------------

    (1+8.306)

       5000

y=  -----------------

    (9.306)

y =537.28

Rounding to the nearest student

y = 537 students


b)  1/2 the student population  means y =2500  (The 5000 is the student population)

             5000

2500=  -----------------

        (1+4999e^-0.8t)

Multiply each side by  (1+4999e^-0.8t)

2500 (1+4999e^-0.8t) = 5000

Divide each side by 2500

(1+4999e^-0.8t) = 5000/2500

(1+4999e^-0.8t) = 2

Subtract 1

(4999e^-0.8t) = 2-1

(4999e^-0.8t)=1

Divide by 4999

(4999/4999e^-0.8t)=1/4999

e^-0.8t=1/4999

Take the natural log of each side

ln(e^-0.8t)=ln(1/4999)

-.8t = ln(1/4999)

Divide by -.8

-.8/-8t = -1/.8 *ln(1/4999)

t = -1/.8 *ln(1/4999)

t≈10.6462

Rounding, it will take 11 days

Find the value of x.
meriva
I forgot the name, but there is a theorem that states that those two angles are equal. So if you do 94=5x+4 , you can solve that.

94=5x+4.
Subtract 4 from both sides
90=5x
Divide both sides by 5
18=x

Hope this helps :)

A book sold 41,900 copies in its first month of release. Suppose this represents 8.1 percent of copies sold to date. How many co
Diano4ka-milaya [45]

The total number of copies that have been sold till date are: 517284

Step-by-step explanation:

Let x be the total number of copies sold

Then

41900 is 801 percent of x

This can be mathematically written as

41900 = 8.1\%\ of\ x\\41900 = 0.081 * x\\x = \frac{41900}{0.081}\\x = 51728.9

Rounding off to nearest whole number

517284

Hence,

The total number of copies that have been sold till date are: 517284
