Step-by-step explanation:
ANSWER:
5.65 ft²
STEP-BY-STEP EXPLANATION:
We have the following measures:
Length (l) = 13 inches
Width (w) = 11 inches
Height (h) = 11 inches
We can determine the surface area as follows:
![\begin{gathered} A=2\cdot l\cdot w+2\cdot l\cdot h+2\cdot w\cdot h \\ \\ \text{ We replacing:} \\ \\ A=2(13)(11)+2(13)(11)+2(11)(11) \\ \\ A=286+286+242 \\ \\ A=814\text{ in}^2 \\ \\ \text{ Convert inches to feet, knowing that 1 foot is equal to 12 inches} \\ \\ A=814\text{ in}^2\cdot\frac{(1\text{ ft\rparen}^2}{(12\text{ in\rparen}^2} \\ \\ A=5.65\text{ ft}^2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D2%5Ccdot%20l%5Ccdot%20w%2B2%5Ccdot%20l%5Ccdot%20h%2B2%5Ccdot%20w%5Ccdot%20h%20%5C%5C%20%20%5C%5C%20%5Ctext%7B%20We%20replacing%3A%7D%20%5C%5C%20%20%5C%5C%20A%3D2%2813%29%2811%29%2B2%2813%29%2811%29%2B2%2811%29%2811%29%20%5C%5C%20%20%5C%5C%20A%3D286%2B286%2B242%20%5C%5C%20%20%5C%5C%20A%3D814%5Ctext%7B%20in%7D%5E2%20%5C%5C%20%20%5C%5C%20%5Ctext%7B%20Convert%20inches%20to%20feet%2C%20knowing%20that%201%20foot%20is%20equal%20to%2012%20inches%7D%20%5C%5C%20%20%5C%5C%20A%3D814%5Ctext%7B%20in%7D%5E2%5Ccdot%5Cfrac%7B%281%5Ctext%7B%20ft%5Crparen%7D%5E2%7D%7B%2812%5Ctext%7B%20in%5Crparen%7D%5E2%7D%20%5C%5C%20%20%5C%5C%20A%3D5.65%5Ctext%7B%20ft%7D%5E2%20%5Cend%7Bgathered%7D)
Therefore, the correct answer is 5.65 ft²
To simplify 2x+3-x+5, we can first group x together,then calculate:
![2x + 3 - x + 5 \\ = 2x - x + 3 - 5 \\ = x - 2](https://tex.z-dn.net/?f=2x%20%2B%203%20-%20x%20%2B%205%20%5C%5C%20%20%3D%202x%20-%20x%20%2B%203%20-%205%20%5C%5C%20%20%3D%20x%20-%202)
Therefore the answer is x-2.
Hope it helps!
The answer is multiplication
Answer:
selecting one item? If you mean each color:
40% chance for a red marble / 2/5 chance
60% chance for a blue marble / 3/5 chance
Step-by-step explanation:
Because there are 12 blue marbles and 8 red marbles, we would total them to see how many marbles there are in total. There are 20 in total, but to find the probability, if we put all 20 marbles in a bag (blue and red), and we picked a marble at random, there are 8 red marbles and 12 blue marble in that bag. The probability that I will choose red marbles is 8/20 (or 8 red marbles out of 20 total marbles), and for blue marbles, it would be 12/20 (or 12 blue marbles out of 20 total marbles). Simplify both expression to 2/5, and 3/5 respectively. Finally, if you need percentage, just multiply the denominator by 5 to get it to a hundred, and do the same to the numerator. This way you don't change the value of the expression.
