Zhao Xue wants to buy milk and yogurt. She wants to buy a total of at least 6.5 gallons of dairy products (condition A), and she
Marta_Voda [28]

Answer: The answer is (D). Zhao Xue doesn’t have enough money left to buy any yofurt


Step-by-step explanation:  Given that Zhao Xue is buying buy milk and yogurt, a total of at least 6.5 gallons of dairy products and she has a budget of $20. The given graph represents the constraints on the number of gallons of milk 'M' and yogurt 'Y' Zhao Xue buys. Zhao Xue buys 4 gallons of milk. We need to calculate the number of gallons of yogurt she can buy to meet both her constraints.

From the graph, we can write

Condition A :

M+Y\geq 6.5.

Condition B :

8M+5Y\leq40.

Now, if she buys 4 gallons of milk, the the conditions become

4+Y\geq 6.5~~\Rightarrow Y\geq 2.5,\\\\8\times 4+5Y\leq 40~~\Rightarrow Y\leq 1.6.

Here, there will be no solution to these constraints.

Therefore, she does not have enough money left to buy any yogurt.

Thus, the correct option is (D).

In the original set of numbers, the median is six
But, if six was added to the set, then the median would be six
So the median wouldn't decrease at all

Use Cramer's rule to find the solution to the following system of linear equations.
slavikrds [6]

Answer:

x = 53

y = 30

Step-by-step explanation:

Step(I):-

Given equations are

x -2y =-7 ...(I)

5x-9y =-5 ..(ii)

The matrix form  AX = B

                    \left[\begin{array}{ccc}1&-2\\ 5  & -9\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}-7\\-5\\\end{array}\right]

The determinant

= \left|\begin{array}{ccc}1&-2\\5&-9\\\end{array}\right| = -9+10 =1

By using Cramer's Rule

Δ₁ =      \left[\begin{array}{ccc}-7&-2\\\\-5&-9\end{array}\right]



The determinant is     Δ₁ = -9 X -7 - (10 ) = 53

x = Δ₁ / Δ

x = 53

The determinant

Δ₂ =



Δ₂ = -5 +35

     

 

y = Δ₂/Δ =  30

Answer:

The volume of rectangular prism is \frac{24}{105} inches³

Step-by-step explanation:

Given as :

The Length of rectangular prism = L = \frac{2}{3} inches

The Breadth of rectangular prism = B = \frac{3}{5} inches

The Height of rectangular prism = H = \frac{4}{7} inches

Let The volume of rectangular prism = V inches³

A rectangular prism is a 3-D figure with 6 faces

Now, <u>From formula of rectangular prism</u>

Volume = Length × width × height

Or, V = L × B × H

Or, V =  \frac{2}{3} inches ×  \frac{3}{5} inches × \frac{4}{7} inches

or, V = \frac{2\times 3\times 4}{3\times 5\times 7} inches³

or, V = \frac{24}{105} inches³

So,  The volume of rectangular prism = V  =  \frac{24}{105} inches³

Hence The volume of rectangular prism is \frac{24}{105} inches³ Answer
