Is it asking you to tell them what the numbers that the letters substitute are??
If so o might be able to help with that
Answer:
41.67 % ( to 2 dec. places )
Step-by-step explanation:
Since 2 dozen cookies were baked, that is 24 and 14 were left.
Then 10 were eaten.
Calculate the percentage eaten as
percentage =
× 100%
percentage eaten =
× 100% ≈41.67%
Answer:
Only the 3rd table shows a proportional relation between x and y.
Step-by-step explanation:
The first table is
x 2 3 5 6
y 3 4 7 9
Here y is not increasing in uniform rate with x. So, the relation is not proportional.
The second table is
x 4 6 8 10
y 6 8 10 12
Here y is increasing in uniform rate with x, but at x = 0, y ≠ 0, Hence, the relationship is not proportional.
The third table is
x 1 5 8 10
y 15 75 120 150
Here, y is increasing in uniform rate with x, and at x = 0, y = 0, Hence, the relationship is proportional.
The fourth table shows
x 3 9 10 15
y 1 3 4 5
Here also y is not increasing in uniform rate with x. So, the relation is not proportional.
Therefore, only the 3rd table shows a proportional relation between x and y. (Answer)
Answer:
d = 5
Step-by-step explanation:
Pythagorean Theorem
a^2 = b^2 = c^2
3^2 + 4^2 = 9 + 16 = 25
sqrt.25 = 5
Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.
