What comes next in the sequence: 1, 3, 11, 43,

1 answer:

6 0

There may be more than one solution, but if we take the difference between the numbers of the sequence, we get
3-1, 11-3, 43-11
=2,8,32
which are powers of 2
=2^1, 2^3,2^5
If we believe the next difference is 2^7=128, then the next in the sequence will be 43+128=171

A system of two equations has no solution. One equation is -15x+y=18.

DerKrebs [107]

If you multiply the original equation by 3 you get -45x+3y=54, which is the exact same as A, therefore they have infinite solutions.

How do you change a decimal by a fraction

Stella [2.4K]

Write down the decimal divided by 1, like this: decimal 1. Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.) Step 3: Simplify (or reduce) the fraction.

Find the volume of soup can if the diameter is 6.5 in and the height is 9 in

Nitella [24]

Answer:

V =298.49625 in^3

Step-by-step explanation:

Volume of a cylinder is given by

V = pi * r^2 *h

We know the diameter so we can find the radius

r = d/2 =6.5/2 = 3.25

and we know the height =9

V = pi * (3.25)^2 *9

V = pi*95.0625

If we approximate by 3.14

V = 3.14*95.0625

V =298.49625 in^3

3) David goes into a candy store with $5.00. He buys 9 peppermints for $0.15

yuradex [85]

<h3>Write an equation that will match the story problem</h3>

$x=(5 - (9 \times 0.15) ) \div 0.25$

Solution:

Given that,

David goes into a candy store with $5.00

Total amount with David = $ 5

He buys 9 peppermints for $0.15 each

And some sour candies. each sour candy costs $0.25

The equation is:

Let the number of sour candies bought be "x"

Then,

Remaining amount after buying pepper mint = $5 - 9 \times 0.15 = 3.65$

Each sour candy cost $0.25

Now the number of sour candies bought is:

$3.65 = 0.25 \times x$

x = 14.6

Thus david can buy 14 sour candies

Thus the equation that will match the story problem is:

$x=(5 - (9 \times 0.15) ) \div 0.25$

Where, "x" means number of sour candies bought
