The greatest number of students to whom 24 pens and 32 pencils can be equally  divided is 8.

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

We have to find the greatest number of students to whom 24 pens and 32 pencils can be equally divided. Let's calculate ratio of pens to pencils and then we will simplify , or we can find find HCF( Highest common factor) of pen & pencils and HCF will be the maximum number of students whom equally pens & pencils will be distributed. Ratio:

⇒ \frac{pens}{pencils} = \frac{24}{32}

⇒ \frac{pens}{pencils} = \frac{3(8)}{4(8)}

⇒ \frac{pens}{pencils} = \frac{3}{4}

So , 3pens + 4 pencils = Pens+ Pencils

⇒  3pens + 4 pencils = Pens+ Pencils

⇒   3x + 4x = 24+ 32

⇒  7x = 56

⇒ x = 8

Therefore, the greatest number of students to whom 24 pens and 32 pencils can be equally  divided is 8.

Answer:

1) x = 8

2) ∠RPS = 36°

Step-by-step explanation:

<u>GIVEN :-</u>

  • ∠QPS = 180°
  • ∠QPR = 7x + 88
  • ∠RPS = 3x + 12

<u>TO FIND :-</u>

  1. Value of x
  2. Measure of ∠RPS

<u>FACTS TO KNOW BEFORE SOLVING :-</u>

In a straight line , if there are two angles such that their sum is equal to straight angle (or 180° in other words) , then those angles are known as linear pair.

<u>PROCEDURE :-</u>

1)

Measure of ∠QPS = 180° and it comprises of ∠QPR & ∠RPS.

⇒ ∠QPR & ∠RPS are linear pair.

⇒ ∠QPR + ∠RPS = 180°

⇒ 7x + 88 + 3x + 12 = 180°

⇒ 10x + 100 = 180

⇒ 10x = 180 - 100 = 80

⇒ x = 80/10 = 8

2)

x = 8. So,

∠RPS = 3×8 + 12 = 24 + 12 = 36°

Please help and explain very easy good luck
Mars2501 [29]

Answer:

-76

Step-by-step explanation:

A positive digit multiplied by a negative digit will result as a negative digit.

So,

6 · -8 = -48

Now if there is a problem where a number is added by a negative digit number, you turn the "plus" sign into a "negative" sign.

So,

- 48 + (- 28)

-48 - 28

If you subtract a negative by a negative, the answer will be negative BUT you have to ADD those two negative digits together and put the negative sign after.

- 48 - 28 = -76

Delicious77 [7]

Answer: There are 667 owls for every 1000 squirrels.

Step-by-step explanation:

Since we have given that

Number of owls = 30

Number of squirrels = 45

If the number of owls and squirrels will continue to increase.

If there are 1000 squirrels, then the number of owls would be

\dfrac{30}{45}=\dfrac{x}{1000}\\\\x=\dfrac{30\times 1000}{45}\\\\x=666.67\\\\x\approx 667

Hence, there are 667 owls for every 1000 squirrels.

What is the length of XY
arsen [322]

Answer:

6

Step-by-step explanation:

We know that MY is the same length as XM according to definition of segment bisector. We can create an equation:

5x + 8 = 9x + 12

Minus 8 on both sides

5x = 9x + 4

-4 = 4x

x = -1

Now substitute both sides of the equation with -1 instead of x

-5 + 8 = -9x + 12

3 = 3

XY = MY + XM

XY = 3 + 3 = 6

Hope this helps :)

Have an awesome day!
