Trey is buying peach and blueberry yogurt cups. He will buy at most 8 cups of yogurt. Let x be the number of peach yogurt cups a
Paraphin [41]

Answer:

8 ≤ x + y

Step-by-step explanation:

First you need to consider what is in the problem.

max number of cups = 8

x = number of peach cups

y = number of blueberry cups

Using this information, create an inequality that represents the situation

8 ≤ total number of cups

total number of cups = x + y

8 ≤ x + y

This is therefore the most representative equation for the situation.

The quantity y varies directly with the square of x and inversely with z. When x is 9 and z is 27, y is 6. What is the constant

\begin{array}{llll}
\textit{\underline{y} varies directly with \underline{x}}\\
\textit{and inversely with \underline{z}}

-------------------------------

\bf \stackrel{\textit{\underline{y} varies directly with the square of \underline{x} and inversely with \underline{z}}}{y=\cfrac{kx^2}{z}}
\\\\\\
\textit{we also know that }
\begin{cases}
x=9\\
z=27\\
y=6
\end{cases}\implies 6=\cfrac{k9^2}{27}
\\\\\\
\cfrac{27\cdot 6}{9^2}=k\implies 2=k

Answer to question first
andrey2020 [161]

Answer:

C. But be careful. It depends if you have been told what I was having trouble with.

Step-by-step explanation:

The question is a little unclear. If the actual interest is constant for all situations, the answer is C. The more times you compound, the more interest you will accumulate. Banks don't do it that way. It they compound every three months, then they cut the interest rate by a quarter.

So the interest would look like (1 + 0.022/4)*principle. Whoever made the question has to make clear what is going on. My guess is the intended answer is C.

Quadrilateral ABCD is inscribed in the circle. If m∠A = 95°, what also must be true?
makvit [3.9K]
Opposite angles in a cyclic quadrilateral add up to 180 degrees .
So the angle opposite angle A ( that is angle C) must be 180-95 = 85 degrees
