Someone please help! i don’t get what it’s asking or how to do it :( worth 12 points

Answer:

2 cubic yards

Step-by-step explanation:

In this problem we are simply finding the volume of a 3D shape. We can calculate this by L × W × H.

9.5 × 12 × 1/3 = 48 ft³

(Note: 4 inches is 1/3 foot)

This means Rosilaine needs 48 cubic feet of wood chips. However, the wood chips are sold in yards, so we need to convert cubic feet to cubic yards.

48 ÷ 27 = 1.777 (repeating decimal)

This means Rosilaine should buy 2 cubic yards of wood chips.

A metal rod 9.4 meters long is cut into two pieces. One piece is three times as long as the other. Find the length of the longer
tresset_1 [31]
2a + b = 9.4

There are 3 parts, 2 go to Rod A, 1 go to Rod B.

9.4 / 3 = 3.13333 recurring

Rod A = 2(3.13)
= 6.26

Rod B =
3.13

Rounding, Rod A = 6.3 , Rod B = 3.1

8w-6(w-4)=2(w+9) <br> please help asap
uranmaximum [27]

Answer:

w = -7.04 and 1.705

Step-by-step explanation:

First lets distribute.

We have 8w-6w(w-4), so let's distribute the -6w to w and -4

8w-6w^2+24w = 2(w+9)

Now for the other side we distribute 2 to w and 9

8w-6w^2+24w = 2w +18

Now we combine like terms

6w^2+32w = 2w +18

Carry both 2w and 18 to the other side

6w^2 +30w -18 = 0

Now we can factor the equation, i used the quadratic method which is x= -b+- the square root of b^2-4ac /2a (in this case x would be w)

Plugging that in:

x= -32 +- square root of 32^2 -4(6 * -18) / 2(6)

-32 +- square root of 1024 +1728 / 12

-32 +- square root of 2752 /12

-32 +- 52.46 /12

x = -32 - 52.46/12   and  -32 + 52.46/12

x=  -84.46/12      and      20.46/12

x= -7.04  and  1.705

so w = -7.04 and 1.705

Sorry this was so complicated, but I hope this helps

If you can get an answer to any question, what would you ask? You toss a fair coin 4 times. What is the probability that (round
Andrew [12]

Answers:

a) 0.0625

b) 0.9375

==================================================

Work Shown:

The probability of landing on heads is 1/2 = 0.5 since both sides are equally likely to land on. Getting 4 heads in a row is (1/2)^4 = (0.5)^4 = 0.0625

The event of getting at least one tail is the complement of getting all four heads. This is because you either get all four heads or you get at least one tail. One or the other must happen. We subtract the result we got from 1 to get 1-0.0625 = 0.9375

You can think of it like this

P(getting all four heads) + P(getting at least one tail) = 1

The phrasing "at least one tail" means "one tail or more".
