Answer:
88
Step-by-step explanation:
this question is a question that involves the use of the statistical principles of finding average
let the summation of the six scores of the biology test be represented as ∑x
∴ ∑x÷ 6=74
∑x=74 × 6
=444
444 is the summation of all the scores of all the six biology scores reuben had
the next test would be his 7th
let y represent the score for the 7th test
therefore, 
= 76
444 + y = (76 × 7)
444 + y = 532
y=88
Reuben needs to score 88 to raise his average to 76
¹¹/48 of the full cup
Step-by-step explanation:
We add the two fraction first to determine the total ratio
¹/4 + ²/3 = ¹¹/12
She uses ¼ cup grape juice for ¹¹/12 cup full of diluted grape juice
Therefore;
¼ : ¹¹/12
How How much grape juice does Sarah use for each full cup of water, i.e ¹²/12
? (x) : ¹²/12
We cross multiply the ratios;
¹²/12 * ¼ = ¹¹/12 * x
³/12 = ¹¹/12 x
³/12 * ¹²/11 = x
¹¹/48 = x
Answer: 26 years old
Step-by-step explanation:
Since Scott is four more than double the age of Todd, start by taking away four from Scott's age.
56-4=52
Then take half of that because that would be double of Todd's age
52/2=26
Todd is 26 years old.
