Let:
y = 3.9x
where y is = the amount of calcium in mg.
x = weight of chicken in ounces.
Check:
For 1 ounce of chicken there are 3.9 mg of Calcium.

Is 16.45 equal to 16.454
Answers
no if it it was 16.450 then it would be equal to 16.45
No, because the values are different by 0.004. However, 16.454 does round to 16.45 if that is what you mean.
Students were surveyed about their favorite colors one fourth of the students preferred red 1/8 of the students preferred blue, and3/5 of the remaining students preferred green. If 15 students prefer green how many students were surveyed
Answers
Let us assume the total number of students surveyed = x Then Number of students preferring red = x/4 Number of students preferring blue = x/8 Then Number of students remaining = x - [(x/4) + (x/8)] =x - [(2x + x)/8) = x - (3x/8) = (8x - 3x)/8 = 5x/8 Number of students preferring the color green = (3/5) * (5x/8) = 3x/8 We also know that the total number of students preferring the color green is 15 So 3x/8 = 15 3x = 15 * 8 x = (15 * 8)/3 = 5 * 8 = 40 So in total 40 students were surveyed. I hope the procedure is clear to you.
Factorise y^2 - 169?????????????
Answers
= y^2 - 169 = (y)^2 - (13)^2 = (y + 2)(y - 2)
Step 1. Rewrite it in the form: , where a = y and b = 13
Step 2. Use Difference of Squares:
Done!
What are some equivalent fractions to 3/4
Answers
There are infinitly many fractons equivalent to 3/4:
All fractions of the form will be equivilant for any 'n'.
6/8 because you have multiplied both the numerator and the denominator by 2.
9/12 ....multiplied both the numerator and denominator by 3.
12/16 ....multiplied both the numerator and the denominator by 4.
So basically just multiply the numerator and debominator by the same number and the fraction you get as your answer is equivalent to 3/4
Hope my answer helped, im not that great at explaining things :D
