Answer:

Step-by-step explanation:

The laptop qualifies for the 15% discount as its original price is over $1000

The discount will be 1100(0.15) = $165.00

The cost of the laptop will be 1100 - 165 = $935.00

The desktop qualifies for the 25% discount as its original price is over $1200

The discount will be 1365(0.25) = $341.25

The cost of the desktop will be 1365.00 - 341.25 = $1,023.75

This is 2.375% larger than his budget of $1000.00

Only the laptop is within the budget.

Solve the inequality.
marysya [2.9K]

Answer:

\huge x >  \frac{7}{3}  \\

Step-by-step explanation:

8( \frac{1}{2} x -  \frac{1}{4} ) > 12 - 2x \\

<u>Expand the terms in the bracket</u>

That's

8( \frac{1}{2} x) - 8( \frac{1}{4} ) > 12 - 2x \\ 4x - 2 > 12 - 2x

Move -2x to the other side of the inequality

4x + 2x - 2 > 12 \\ 6x - 2  > 12

<u>Move - 2 to the other side of the inequality</u>

6x > 12 + 2 \\ 6x > 14

Divide both sides by 6

\frac{6x}{6}  >  \frac{14}{6}  \\

We have the final answer as

x >  \frac{7}{3}  \\

Hope this helps you

Find the volume of the wedge cut from the first octant by the cylinder z=12-3y^2 and the plane x+y=2.
LuckyWell [14K]

Answer:

The wedge cut from the first octant ⟹ z ≥ 0 and y ≥ 0 ⟹ 12−3y^2 ≥ 0 ⟹ 0 ≤ y ≤ 2  

0 ≤ y ≤ 2 and x = 2-y ⟹ 0 ≤ x ≤ 2  

V = ∫∫∫ dzdydx  

dz has changed from zero to 12−3y^2  

dy has changed from zero to 2-x  

dx has changed from zero to 2  

V = ∫∫∫ dzdydx = ∫∫ (12−3y^2) dydx = ∫ 12(2-x)-(2-x)^3 dx =  

24(2)-6(2)^2+(2-2)^4/4 -(2-0)^4/4 = 20
