Answer:
-4 C (Negative 4 C)
Step-by-step explanation:
If its 20 C less in Moscow, then it must be 16-20 = - 4 C in Moscow.
Look up rules on subtracting large numbers from small numbers to understand how I got - 4.
Moscow: 20 degrees colder
16-20= -4

A tank is 1/2 filled with water. some of the water is then poured into 8 small containers each with a capacity of 27 cubic centimeters. the tank is now 1.4 full. what is the capacity of the tank.
Answers
The capacity of the tank is 240 cm³.
What is capacity?Capacity means the volume of a solid shape.
To calculate the capacity of the tank, we use the formula below.
Note: When the water from the 8 small containers is poured into the tank that was initially half full, becomes 1.4 full that means the water from the 8 small containers fills the tank 0.9
Formula:
V = (8×27)/0.9............... Equation 1Where:
V = Volume or capacity of the tankSolve for V
V = 240 cm³.Hence, the capacity of the tank is 240 cm³.

Answer:
It's 30.72
Step-by-step explanation:
Take your total and times it by the percentage (20 in this case) and then divide by 100.
total: 25.60$
tip: 20% of total
25.60 * 20 = 512
512/100 = 5.12
25.60 + 5.12 = 30.72
Can someone explain scientific notation to me? And also another question. Is 9.725 x 10^6 a scientific notation? What about 9.7250 x 10^6
Answers
Both of those values are in scientific notation
Scientific notation is when we have numbers of the form [tex]a \times 10^b[/tex] where [tex]0 \le a < 10[/tex] and b is an integer.
Both 9.725 and 9.7250 are inside the inequality mentioned above.
Scientific notation is used to help describe very large numbers, or very small numbers, depending on context.
---------------
If you wanted to convert from scientific notation to standard notation, then you'll move the decimal point based on what the exponent is. The positive 6 means we move the decimal point 6 places to the right.
We go from 9.725 to 9,725,000 which is about 9.7 million
In other words, [tex]9.725 \times 10^6 = 9,725,000[/tex]
As another example, [tex]1.23 \times 10^{11} = 123,000,000,000 = \text{123 billion}[/tex] since we start at 1.23 and move the decimal point 11 spots to the right to arrive at 123,000,000 aka 123 billion.

Two cards are drawn from a deck of 52 playing cards. The first card is NOT replaced into the deck before the 2nd card is drawn. What is the probability of first drawing an Ace, then a Two?
Answers
Answer:
4/663.
Step-by-step explanation:
There are 4 aces and 4 2's in a pack of cards.
Prob(First drawing an Ace) = 4/52 = 1/13.
After drawing this card there are now 51 cards left, so:
Prob(Next drawing a 2) = 4/51.
Required probability
= 1/13 * 4/51
= 4/663
Answer:
First, we need to keep in mind that there are 52 cards in a deck.
Second, we need the probability of getting an ace.
[tex]\frac{4}{52\\}[/tex] = [tex]\frac{1}{13}[/tex]
Now that that card is taken out of the deck, we need to subtract that card from the total amount of cards. Now there will be 51 cards.
Next, we need to find the probability of getting a 2. Like the Ace, there 4 of them.
So,
[tex]\frac{4}{51}[/tex]
Now, we multiply both of the probabilities.
[tex]\frac{1}{13} * \frac{4}{51} = \frac{4}{663}[/tex]
Since we cannot Reduce, There is your answer!
[tex]\frac{4}{663}[/tex]

Answer:
She has enough to make 4 batches of peanut butter and 6 batches of chocolate chip.
Step-by-step explanation:
26/2 = 13. There's enough flour to make the recipe 13 times over, however,
she only has the amount of butter to make a dozen of the first recipe. 9 divided by (3/4) = 12.
26/3 = 8.6, or 8 and 3/4ths of a batch with the flour. She has enough butter to make 9, but not enough flour, so she could make 8 batches of chocolate chip cookies.
She can make 12 batches of peanut butter cookies alone. Or she could make 8 batches of chocolate chip cookies alone. This means: It can't be C because she doesn't even have enough ingredients to make 22 batches of chocolate chip. It also can't be D because there's not enough ingredients for 28 batches of peanut butter or 12 chocolate chip.
to make 4 batches of PB:
[tex](4)\frac{3}{4}=3[/tex] cups of butter needed, and 4(2) = 8 cups flour needed.
so now she'd have 6 cups butter and 18 cups flour leftover.
This means, to make 6 batches CC:
3(6) = 18 cups flour, and 1(6) = 6 cups butter needed. She has enough to make 4 batches of peanut butter and 6 batches of chocolate chip.

On the map at the right, the public swimming pool can be represented by the point (-6, 5) and Tim’s house can be represented by the point (1, 5). If each unit on the graph represents 0.5 miles, how many miles is Tim’s house from the pool
Answers
The distance between the swimming pool and Tim's house is 3.5 miles.
How to find the distance?
First, we need to find the distance between the two points, and then we multiply that by 0.5 miles.
The distance between the points (-6, 5) and (1, 5) is:
[tex]d = \sqrt{(-6 - 1)^2 + (5 - 5)^2} = 7[/tex]
Now, changing to miles, we get:
d = 7*0.5mi = 3.5mi
So the distance is 3.5 miles

Answer is 41 ft
Step-by-step explanation:
From the right angled triangle above, two sides are known. That is the adjacent and opposite. The hypotenuse is not known so we represent it with a variable say h
Using Pythagora's theorem we have,
[tex] {h}^{2} = {12}^{2} + {12}^{2} \\ {h}^{2} = 144 + 144 \\ {h}^{2} = 288 \\ h = \sqrt{288} \\ h = 12 \sqrt{2} [/tex]
Having found the value of the third side, the perimeter of the triangle can now be determined by summing up the length of all the sides.
[tex]perimeter = adjacent + opposite + hypotenuse \\ p = 12 + 12 + 12 \sqrt{2} \\ p = 24 + 12 \sqrt{2} \\ p = 40.97 \\ to \: the \: nearest \: whole \: number \\ p = 41 \: ft[/tex]
Therefore the perimeter of the triangle is 41 ft.

f(x) = -(x + 1)^2
From the question, we have:
Vertex = (-1, 0)
Because the function has a negative leading term i.e. the negative sign at the beginning of -(x + 1)^2.
It means that the function is always negative.
Also, the domain of the function is all sets of real number, because it is an exponential function.
The y value of the vertex is 0 and the function is always negative. So, the range is all set of all real numbers less than or equal to 0
The x value of the vertex is -1 and the function is always negative. So, the function is decreasing from x = -1 to infinity
