Answer:

Answer: 544

Step-by-step explanation:

The Surface Area of a Cuboid

Given a cuboid (rectangular prism) of dimensions x,y, and z, the surface area is calculated as follows:

[tex]S=2(xy+yz+xz)[/tex]

The dimensions of a given cuboid are x=28 cm, y=4 cm, z=5 cm, thus:

[tex]S=2(28*4 + 4*5+ 28*5)[/tex]

[tex]S= 2*272 = 544[/tex]

The surface area is [tex]544 cm^2[/tex]

The drama club is selling gift baskets to raise money for new costumes. During the fall play, they sold a combined 28 regular gift baskets and 24 deluxe gift baskets, earning a total of $1,188. During the spring musical, they sold 28 regular gift baskets and 13 deluxe gift baskets, earning a total of $836. How much are they charging for the different sized gift baskets?

The drama club is charging $____ for a regular gift basket and $____ for a deluxe gift basket.

Answers

Answer:

28

Step-by-step explanation:

Hi! So what we're gonna want to do here is set up a system of equations. Lets say x = regular baskets and y = deluxe baskets. You would set up the system like this:

28x + 24y = 1,188

28x + 13y = 836

So since the number before the x is the same in both equations, we are going to want to cancel that out.

28x + 24y = 1,188

-1(28x + 13y = 836)

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

28x + 24y = 1,188

-28x - 13y = -836

Add the two equations together! There will be no x value :)

11y = 352

y = 32... The deluxe basket is going to cost $32

Put the y value into one of the equations to solve for x.

28x + 13(32) = 836

28x + 416 = 836

28x = 420

x = 15... The regular basket will cost $15

Hope this helps!

Answer:

4 12/18, simplified is 4 6/9

Step-by-step explanation:

You change the fractions to improper fractions so 10 1/2 to 21/2 and 2 1/4 to 9/4. Since we can't divide, we change 9/4 to 4/9 and multiply. 21 times 4 is 84 and 2 times 9  is 18.  Since that is an improper fraction, we have to change it to a mixed number. 18 can go into 84 4 times, and 18 x 4 is 72. 84 minus 72 is 12 so the final answer is 4 12/18 (simplified 4 6/9)

Step 1: Simplify both sides of the equation.

−4x+5−13x+39=180

(−4x+−13x)+(5+39)=180(Combine Like Terms)

Step 2: Subtract 44 from both sides.
