Mathematics

Viktor [21]3 years ago
7 0

Answer:

For example, 6(1001) + 3(110) = 6006 + 330 = 6336 is a palindrome. Since 11 is a factor of both 1001 and 110, we conclude that all four digit palindromes are divisible by 11.

Solve the following: If 7a – 4b = 3, then b =
WITCHER [35]

Answer:

D (7a-3)/4

Step-by-step explanation:

7a – 4b = 3

Subtract 7a from each side

7a-7a – 4b = 3-7a

-4b = 3 -7a

Divide by -4

-4b/-4 = (3-7a)/-4

b = (7a-3)/4

A student wants to find point C on the directed line segment from A to B on a number line such that the segment is partitioned i
olganol [36]

Answer:

<u>Point C at (-18/7)</u>

Step-by-step explanation:

Point A is at -6 and point B is at 2.

So, the distance between A and B = 2 - (-6) = 8

point C on the directed line segment from A to B on a number line such that the segment is partitioned in a ratio of 3:4.

Let the distance AC = x

∴ BC = 8 - x

AC : CB = 3 : 4

∴\frac{AC}{CB} =\frac{3}{4} = \frac{x}{8-x}

Using cross multiplication

3 (8-x) = 4x

24 - 3x = 4x

24 = 7x

x = 24/7

So, Point C = -6 + 24/7 = -18/7

Point C at (-18/7)

The number N = 100+100^2+100^3 + ... +100^n . Find the least possible value of n such that the number N is divisible by 11.
soldier1979 [14.2K]

It's a big alphabet, why confuse us with N and n?

Anyway, this one is a bit easier than it looks.  We're going to look at it mod 11, meaning we're only interested in the remainders when we divide by 11.  The nice thing about multiplication and addition is if we're going to take the remainder at the end, we can also take the remainders at the beginning and along the way and get the same answer, with smaller numbers.

That all sounds very complicated.  It's easier explained.

100 =9*11 +1 so has remainder 1 when divided by 11.  So if we multiply by 100 that's not going to change the remainder when we divided by 11; it's like multiplying by 1.

So 100, 100^2, 100^3, etc all have remainder 1 when divided by 11.  So we need to add up 11 of them to get a number that's divisible by 11.

Answer: 11

Tyler's height is 57 inches. What could be his height in centimeters? Explain your resoning. Nost: 1 inch=2.54 centimeters
AfilCa [17]

Answer:

Tyler's height in centimeters is, 144.78 centimeters.

Step-by-step explanation:

Given the statement: Tyler's height is 57 inches.

To find his height in centimeters.

Using the conversion:

1 {\tex}inch = 2.54 {\tex}centimeters

Proportion states that the two ratios or fraction are equal.

Using proportion method:

\frac{1}{57} = \frac{2.54}{x}

By cross multiply, we get

x = 57 \times 2.54 = 144.78 centimeters.

therefore, his height in centimeter is, 144.78 inches.
