Write the ratio as a unit rate. Simplify. 216 diving student and 12 instructor

Answers

Answer:

Ratio students to classroom in school A equals 216:12 which simplifies to 18:1. Ratio students to classroom in school B equals 104:4 which simplifies to 26:1.Total students combining school A and B equals 216+104=320 and Total classroom 12+4=16, if both school combined are assumed to be a single school C, than ratio of of students to the classroom in school C equals 320:16 which simplifies to 20:1 which means 20 students in every classroom, now total students in 4 classroom of School C equals 20x4=80, these 4 classroom are separated as School B and other 12 classroom School A, now ratio still 20:1 (same in both schools). initially students in School B were 104 and now are 80, then total students transferred equals 104-80= 24.

If a+b>a−b, which of the following must be true?
(A) a>b
(B) a=b
(C) a 0
(E) b > 0

Answers

Hi

a+b > a-b

<=> a+b-a = b > a-b-a=-b ** subtract a **

<=> b+b > 0 ** add b **

<=> 2b > 0 ** divide by 2 **

<=> b > 0

so (E) is the right answer

Answers

Answer:

-6

Step-by-step explanation:

Answer:

-6/1 or just -6

Step-by-step explanation:

15/4 ÷ (-5/8) is -6/1 .

Find the reciprocal of the divisor

Reciprocal of (-5/8) : (-8/5)

Now, multiply it with the dividend

So, 15/4 ÷ (-5/8) = 15/4 × (-8/5)

= 15 × (-8)  = -120

   4 × (-5)   =  -20

After reducing the fraction, the answer is -6/1 or just -6.

The point is on the x acis and 12 units to the left of y axis

Answers

Answer:

(-12, 0)

Step-by-step explanation:

They are asking for the coordinates of the given point on the plane.

Therefore, since the point is on the x axis, we know that its y-coordinate must be zero. y = 0

Now, since it is 12 units to the left of the y axis, then its x coordinate is -12

x = -12

Therefore, the point in plane coordinates is written as: (-12, 0)

Write the expanded form of the expression.

The French scholar C. J. de Guignes observed that groups of hieroglyphs in Egyptian texts were often enclosed by an oval outline, which he called a cartouche. "Cartouche" is a French word that originally meant a cartridge, and the line around the hieroglyphs had a similar shape. De Guignes guessed rightly that the cartouches in hieroglyphic inscriptions were intended to draw attention to important names, probably the names of Egyptian rulers.Based on this excerpt, what is the authors view of the progress made in the 1700s?A. A French scholar first used the term cartouche to describe hieroglyphs.
