Answer: No, the triangular numbers are not a direct variation. There is not a constant of variation between a number and its position in the sequence. The ratios of the numbers to their positions are not equal. Also, the points (1, 1), (2, 3), (3, 6), and so on, do not lie on a line.
The total pages in the book are 46.
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Rosa read 10 pages of a book on Monday. She read 1/3 of the remainder on Tuesday, and she still had 24 pages to read,
Let the total number of pages be x,
Establishing the equation, we get,
10+(x-10) / 3+24 = x
30 + x - 10 + 72 = 3x
92 = 2x
x = 46
Hence, The total pages in the book are 46.

Answer:
There are 46 pages in the book.
Step-by-step explanation:
if she already read 10 pages of the book and the remainder is split into 3rds and she already read 1/3 of the book then the 24 pages get divided by the 2/3 left which equals 12 so each third is 12 pages so 12 x 3 = 36 + 10= 46
There are 46 pages in the book.
y=1/2x^2-4
if the equation is h= -2x^2 + 12x -10 how do I find the max height?

Answer C I think
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
m<1+m<2+m<3 = 180 this forms a straight line
m<2 = 90 degrees
m<1 + 90 + m<3 = 180
Subtract 90 from each side
m<1 + 90-90 + m<3 = 180-90
m<1 + m<3 = 90
70 +m<1+m<2 = 180 this forms a straight line
70 + m<1 + 90 = 180
Combine like terms
160 + m<1 = 180
Subtract 160 from each side
160-160 + m<1 = 180-160
m<1 = 20
m<1 + m<3 = 90
20 + m<3 = 90
Subtract 20 from each side
20-20 +m<3=90=20
m<3 = 70
We want to find m<3 - m<1
m<3 - m<1
70 -20
