Answer:
-9 + 21 = t t = 12°C.
Step-by-step explanation:
For this problem lets have t be equal to the original temperature in the beginning of the day. The equation -9 + 21 = t represents this situation because it states that if we add the degrees that dropped to the current degrees it will give us our original degrees. Solve. -9 + 21 = t (Simply add -9 + 21) -9 + 21 = (+12) 12 = t So, the original degrees in the beginning of the day was 12°C.
That's a very interesting question.
Here's the way I thought about it, and the answer I came up with
while avoiding the need to define and count every possible outcome:
-- There are (2 x 2 x 2 x 2) = 16 possible outcomes of 4 flips.
-- There are several different ways to get 1 heads and 3 tails.
-- There are several different ways to get 2 heads and 2 tails.
-- There are several different ways to get 3 heads and 1 tails.
-- But there's only one way to get heads all 4 times,
and there's only one way to get tails all 4 times.
-- So there are 2 ways for all 4 flips to produce the same face.
The probability of that is 2/16 = 1/8 = 12.5% , and I'm saying
that this is the least probable result of 4 flips.
Step-by-step explanation:
answer of number 5
length=7cm
breadth=9 cm
height=6 cm
volume=?
we know
v =l×b×h
=7×9×6
=378
so, the volume is 378 cm
Write an equation.
You have 20 dollars as a budget, add to the equation.
20
Add the cost of the book
20 = 12
Then, add the luggage tag cost.
20 = 12 + 2x
Solve for x by subtracting 12 from both sides
8 = 2x
Divide by 2
4 = x
4 is your answer
