Freddy is buying wings and nachos for a party. a box of ten wings cost $7.00 Nachos cost $4.00 per tray. He must spend less than
soldi70 [24.7K]
Hey there! The answer is 7x + 4y < 40

Let's first rearrange our data in a more structured way.

x represents a box of wings which has a cost of $7.00. Therefore the total cost of the boxes is 7x.

y represents a tray of nachos which has a cost of $4.00. Therefore the total cost of the trays is 4y.

The sum of the costs of trays and boxes, which is (7x + 4y) must be smaller than $40.

Now we can set up the inequality.
7x + 4y < 40

~ Hope this helps you!

Note that \displaystyle{ \sin30^{\circ}= \frac{1}{2} and \displaystyle{ \cos30^{\circ}= \frac{ \sqrt{3}}{2}.

From the unit circle, we can check that \sin30^{\circ} and \sin(-30)^{\circ} have the same value, but opposite signs, that is:

\sin(-30)^{\circ}=-\sin(30)^{\circ}=-\frac{1}{2}. 


Thus, 
\displaystyle{ \cos(x-y)= \cos(-30^{\circ}-60^{\circ})=cos(-90^{\circ}).


Note that cos(-90^{\circ}) is the x-coordinate of the lowest point on the unit circle, that is (0, -1). Thus cos(-90^{\circ})=0

Order -1.75 , 3/11 , 0.3 , -1 7/9 from least to greatest
arsen [322]

Answer:

-1 \frac{7}{9}, -1.75, 3/11, 0.3

Step-by-step explanation:

Negatives are always less then positive, so they would go first since its least to greatest.

7/9 = 0.77 which means -1 7/9 = -1.77, therefore it is less then -1.75

-1.75 would be next

3/11 = 0.2 which is less then 0.3 so it would go next.

and at last, goes 0.3 as the greatest number.
