Answer:

1) Yes, 1/2 and 2

2) b=1/2 × t

t=2 × b

Step-by-step explanation:

1) Yes, because <em>every</em> package of a toy equals 2 batteries. The constant of proportionality is 1/2 and 2 because 1 ÷ 2 = 1/2 and 2 ÷ 1 = 2 (amount of toys divided by amount of batteries and vice versa)

2) b = 1/2t, because for every battery, there is 1/2 a toy.

t = 2b, because for every toy, there are 2 batteries

<em>note: you can't actually have 1/2 a toy, </em><em>but</em><em> </em><em>we</em><em> </em><em>write</em><em> </em><em>it</em><em> </em><em>like</em><em> </em><em>that</em><em> </em><em>for</em><em> </em><em>the</em><em> </em><em>sake</em><em> </em><em>of</em><em> </em><em>showing</em><em> </em><em>the</em><em> </em><em>relationship</em><em> </em><em>of</em><em> </em><em>toy</em><em> </em><em>to</em><em> </em><em>battery</em><em>. </em>

60 G of Henry's favorite breakfast cereal is 1/4 sugar how much sugar is in a 60g serving converted
katrin2010 [14]

Answer:

Step-by-step explanation:

Fraction of sugar in 60 gram cereal = 1/4

1/4 parts means that if 60 gram sugar is divided into four parts then out of that one part is sugar.

Amount of sugar in cereal in grams = 1/4 of 60 gram

Amount of sugar in cereal in grams = 1/4 * 60 gram = 15 grams.

Therefore, 15 grams sugar is in a 60 gram serving converted.

Which of the following is the reciprocal of x2 – 2x – 8?
Ann [662]
Hi again

x² - 2x - 8
Factor
= (x + 2)(x -4)
Answer : A is the correct option.


If you wanna check if A is the right answer, I will solve it for you and it will you give you the exact answer which will be x² - 2x - 8
(x+2)(x-4)
Distribute
(x)(x) + (x)(-4)+(2)(x)+(2)(-4)
= x² - 4x + 2x - 8
= x² - 2x - 8
Here it is, we find the exam answer.

Thus, (x+2)(x-4) is the reciprocal of x² -2x - 8
