The explicit formula for this geometric sequence is 27.3(n-1)
Answer:
What's your question?
Step-by-step explanation:
Multiply 9 books by 55% by doing
9 x .55 = 4.95
We can't have 4.95 books, though so it rounds down to 4 because you can't just add another .05.
First, we need to find the total fraction of her raisins she used:
1/4 + 3/8 = 2/8 + 3/8
She used 5/8 of her supply.
Knowing this:
5/8x = 5
We multiply by 8 (the LCD)
5x = 40
x = 8
Her supply was 8 pounds, and after making the food, she now has 3 pounds
The answer is <span>She went over by one over six of a cup
</span>
<span>1 cup of that particular chocolate powder has a mass of 128 grams: 1c = 128g
</span><span>64 grams of chocolate powder is x cups.
1c = 128g
x = 64g
1c : 128 g = x : 64g
x = </span>1c : 128 g * 64 g
x = 0.5 c
64 grams of chocolate powder is 0.5 cups = 1/2 cups
<span>She added two over three of a cup of chocolate powder: 2/3 cups
She need to add 1/2 cups: 1/2 = 3/6 cups
She added 2/3 cups: 2/3 = 4/6 cups
So she added 4/6 - 3/6 = 1/6 cups more.
