Below for question 10.

Mathematics
1 answer:
Monica [59]3 years ago
3 0

Answer:

3/56

Step-by-step explanation:

There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to \frac{1}{8} times \frac{3}{7}, which is equal to \frac{3}{56}.

Hope this helps! :D

Ghella [55]

to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:

\frac{20}{3/5}  = \frac{x }{1 }

you can use cross multiplication to solve for x:

\frac{3}{5} x = 20

3x = 100\\x = 100/3

so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.

Dafna1 [17]

Answer:

Step-by-step explanation:

Just multiply the sides. For example, the roses take 8x4=32 feet. if we want to know the area of Zinnias, we multiply the sides 8x12 and remove the roses, which would be 8x12-32=96-32=60 for the Zinnias.

For a)

The roses take 8x4

Zinnias take 8x12 - roses

Snapdragons take 16x12 - roses - zinnias

Petunias take 16x20 - snapdragons - zinnias- roses

b) The entire area of the garden is 20x16=320 square feet

The area of the Zinnias(including roses) is 8x12 = 96 square feet

To get the percent, we divide the smaller number by the bigger number and multiply by 100 or in practice 96/320x100=30%

c) Let's see the progression here. The width progresses in the first rectangle by four 8 to 12, then again by four 12, 16 and again by four 16 to 20, which means that the next rectangle would have a width of 20+4=24. Doing the sale analysis for the height, we get that the increase is with 4 feet at a time or the new rectangle would have a width of 24 and height of 20, which means a total area of 480 feet. We have to subtract all other rectangles or the new area would be 480 - (20x16) = 160 square feet
