Answer:
The required ratio is 9 : 61
Step-by-step explanation:
Given,
$72 for 488 photos,
That is, the price of 488 photos = 72 dollars,
So, the ratio of price of photos and number of photos = 
∵ HCF(72, 488) = 8,
Thus, the ratio of price of photos and number of photos = 
= 
Using subtraction of perfect squares, it is found that the factored expression is:
9t² - 4 = (3t - 2)(3t + 2).
<h3>What is the subtraction of perfect squares factoring?</h3>
It is given as follows:
a^2 - b^2 = (a - b)(a + b)
In this problem, the binomial is given as follows:
9t² - 4.
Hence:
Hence the factored expression is:
9t² - 4 = (3t - 2)(3t + 2).

11 since you’d divide 861 by 25, but you’d still not get a whole number so you’d get that as a remainder. then you’d divide .44 by 25 and get 11, cause there was 25 marbles in each bag.
just count how many there and and eliminate one by one
The answers 59 because 90 degrees is the angle so 21 plus 10 equals 31 and 90-31 equals 59
