Answer:

176521221 divisible by 9 but not by 11

149235678 divisible by 9 but not by 11

Step-by-step explanation:

There are rules that can be used to determine if a number is divisible by other. We will use the following:

- A number is divisible by 9, if the sum of its digits is divisible by 9.

- A number is divisible by 11, if the alternating sum of the digits read from left to right is divisible by 9.

Let's apply this rules to the given numbers...

For 176521221:

  • 1 + 7 + 6 + 5 + 2 + 1 + 2 + 2 + 1 = 27, and  27 divisible by 9 => 176521221 divisible by 9
  • 1 - 7 + 6 - 5 + 2 - 1 + 2 - 2 + 1 = -3, and -3 not divisible by 11 => 176521221 not divisible by  11

For 149235678 :

  • 1 + 4 + 9 + 2 + 3 + 5 + 6 + 7 + 8  = 45, and 45 divisible by 9 => 149235678 divisible by 9
  • 1 - 4 + 9 - 2 + 3 - 5 + 6 - 7 + 8  = 9, and 9 not divisible by 11 => 149235678 not divisible by  11

Find the values of x and y.<br><br> Show steps
algol [13]

Answer: x=90° y=43°

Step-by-step explanation: Right away you may be able to tell that x is a right triangle, which is 90°. Now, look at the two small lines cutting through some of the triangle. That means the sides are congruent, and that the bottom two angles are the same. So if angle C is 47°, then so is D. A triangle has 180° in total. So since we already have 47° and 90°, subtract 47 and 90 from 180 to get angle y.

Find the value of Y .
DerKrebs [107]

Answer:  (C) 4

<u>Step-by-step explanation:</u>

The corresponding sides of a 30°-60°-90° triangle are: b - b√3 - 2b

The side corresponding to 90° is 8 = 2b   --> b = 4

The side corresponding to 30° is  y = b  <em>as stated above, b = 4</em>, so y = 4

Martin is an after school math tutor . He noticed that 6 people still needed help on 2/5 of the tutoring session time was left.S
iVinArrow [24]

Answer:

6/15 ÷ 6

Step-by-step explanation:

Martin is an after school math tutor

He noticed that 6 people still needed help on 2/5 of the time that was left

Martin wrote the expression

2/5 ÷ 6

This expression can be used to determine the number of persons who still need help

Therefore the expression that is equivalent to Martin's expression is

= 6/15 ÷ 6

Using 3 to divide both 6 and 5 will give

2/5 ÷ 6

Hence the expression which is equivalent to Martin's expression is 6/15 ÷ 6

Describe a point. what could you use as a model of a point ?
NNADVOKAT [17]

A point is an exact location.
It has no length, width, or height.
It has no area or volume.
It has no mass, shape, or other physical properties.

As a model ...

-- you could use the period at the end of a sentence printed on paper.
     It looks like this  ==> ·

-- You could use the point of a very sharp pencil.

-- You could use the tiny dot that the point of
a very sharp pencil makes on paper.

-- You could use the point of a pin.

-- You could use the tiny hole that the point of
a pin makes in a sheet of paper.

These are all bigger than a real point.  They all have a little bit of size,
length, width, height, and you can see them.  But they get the idea across.
(They 'make the point'.)
