what is the least whole number that has the remainders 10,12, and 15 when divided by 16, 18. and 21, respectively

Answers

Answer:

[tex]1002[/tex]

Step-by-step explanation:

First find difference between the divisors and remainders.

[tex]16-10=6\\18-12=6\\21-15=6[/tex]

Here, the difference between the divisors and remainders is equal.

So, the required number is equal to LCM of [tex](16,18,21)-6[/tex]

[tex]16=2^4\\18=2(3^2)\\21=3(7)[/tex]

LCM of [tex](16,18,21)=2^4(3^2)(7)=1008[/tex]

Required Number [tex]=1008-6=1002[/tex]

The Jones have some friends drop in. They wish to serve sherry but do not have enough to serve all the same kind. So they mix some which is 20% alcohol with some which is 14% alcohol and have 5 quarts, which is 16% alcohol. How much of each king of sherry they have to mix

Answers

Answer:

they have to mix 1.67 quarts 20% and 3.33 quarts 14%

Step-by-step explanation:

Given the data in the question;

let x quarts of the 20 percent alcohol and y quarts of 14 percent alcohol be mixed to form 5 quarts

i.e

x + y = 5  -------------let this be equation 1

20%x + 14%y = 16%5

0.2x + 0.14y = 0.8

multiply through by 50

10x + 7y = 40 -------------let this be equ 2

so let multiply equation by -7

-7x - 7y = -35       ------------- let this be equ 3

add equ 2 and 3

3x + 0 = 5

x = 5/3 ≈ 1.67

substitute value of x in equation 1

5/3 + y = 5

y = 5 - 5/3

y = 10/3 ≈ 3.33

Therefore; they have to mix 1.67 quarts 20% and 3.33 quarts 14%

What is 2y+4x =10 in y=mx+b

Answers

Answer:

The answer should be y = -2x + 5

Step-by-step explanation:

Subtract 4x to move it to the other side.

(2y = -4x + 10)

Then you divide both sides by 2 to get y by itself.

rate of 7.2% per year.
What will the population be in 6 years?

Answers

Answer:

The population in 6 years will be 42,960.

Step-by-step explanation:

First, multiply 7.2% or 0.072 and 30,000 which will give you 2,160.

Then, 2,160 by the number of years (6) which is 12,960.

Lastly add 12,960 and 30,000 to get 42,960.

Find the point slope equation of the line through (10, -4) with a slope of -6.

Answers

Answer:

y=-6x+56

Step-by-step explanation:

The point-slope equation of a line is given as

y=mx+c   where m is slope and c is y-intercept of a line.

We are given m=-6 and a point (10,-4) which can be put into y=mx+c to find the only unknown c. Thus,

c=-4+6x10=56.

Now we can easily form the point-slope equation of the line

y=-6x+56.
