The difference between the new, colder temperature and the original temperature is 30 ° C.
What is temperature ?"Temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; e.g., a burning match is at a much higher temperature than an iceberg, but the total heat energy contained in an iceberg is much greater than the energy contained in a match. Temperature, similar to pressure or density, is called an intensive property—one that is independent of the quantity of matter being considered—as distinguished from extensive properties, such as mass or volume."
Given,
The old temperature is = 18°C
The new temperature is = -12°C
The difference in temperature is [tex](-12\°C - 18\°C) = 30\°C[/tex]
Hence, A is the correct option.

Answer:
D. 0.5
Step-by-step explanation:
There are 4 groups
1. Alto
2. Bass
3. Tenor
4. Soprano
The question says "what is the probability that this member comes from the alto section"
Since there are 4 groups, I did 4/8 (since there are 8 people in Alto) and I got 0.5.
Hope I got it right and it helped you
*Note* I most likely got it right I just doubt myself too much lol
But just in case, I hope I got it right.
Answer:
there are 4 parts in that choir and the alto members are 8 in number so we say those in alto divided by the number of parts, we get→ 4÷8 =0.5, that's the ans.
Luke went to a blackjack table at the casino. At the table, the dealer has just shuffled a standard deck of 52 cards.
Luke has had good luck at blackjack in the past, and he actually got three blackjacks with Queens in a row the last time he played. Because of this lucky run, Luke thinks that Queens are the luckiest card.
The dealer deals the first card to him. In a split second, he can see that it is a face card, but he is unsure if it is a Queen.
What is the probability of the card being a Queen, given that it is a face card? Answer choices are in a percentage format, rounded to the nearest whole number.
a) 8%
b) 4%
c) 33%
d) 77%
Answer:
c) 33%
Step-by-step explanation:
In a standard deck of cards, there are 52 cards total and of those 52, there are 12 face cards. One-third of those face cards are queens, (because there are 4 queens in a deck of cards, and [tex]\frac{4}{12}=\frac{1}{3}[/tex]). Therefore, there is a 33% chance that the card Luke holds is a queen.
Answer:
33%

Answer:
x=10
Step-by-step explanation:
2x-10=10
2x=20
x=10
Answer:
x=10
Step-by-step explanation:
2(x - 5) = 10
You would first multiply 2 by x and 5
2x-10 = 10
then you would add ten to both sides
2= 20
then you would divide 2 by 20

Answer:
(0,6)
(1,5)
(2,4)
(3,3)
(4,2)
Step-by-step explanation:
To solve this table first convert the equation to slope-intercept form (y=mx+b), to do this solve for y in the equation. The slope-intercept form is y=-x+6, where -1 is the slope and 6 is the y-intercept. Then from that, you can get your first point, because you know the y-intercept is 6, therefore when x equals 0 y must be 6. Next, because the slope is -1 that means the y-value decreases by 1 every time the x-value increases by 1. So to find the rest of the y-values simply subtract 1 from the previous y-value.

At the neighborhood grocery, 55 pounds of steak cost \$20.60$20.60. How much would it cost to buy 44 pounds of steak?
Answer:
$16.48
Step-by-step explanation:
Create a proportion where x is the cost of 44 pounds of steak:
[tex]\frac{55}{20.60}[/tex] = [tex]\frac{44}{x}[/tex]
Cross multiply and solve for x:
55x = 906.4
x = 16.48
So, the cost of 44 pounds of steak is $16.48

What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
Explanation:
We want to find the correct second step for the given proof.
Recall that from division property of equality, when we have;
a=b and c=d, dividing the equations by each other, the equation will still be equal;
a/c = b/ d
For the given Prove;
statement 1 states that the circumference circle 1 and 2 can be expressed as;
C = 2πr and, C' = 2πr'
So, for step 2;
Applying the division property of equality, we have;
C/C' = 2πr/2πr'
which then equals,
C/C' = r/r'
Therefore, the correct second step for the given proof is;
C/C' = 2πr/2πr' and, C/C' = r/r'
by the division property of equality.

Answer:
He would drive 536 miles in 5 hours
Step-by-step explanation:
First set up your equation:
804 = 12x
Divide 804 by 12 and get 67 = x
Since per one hour you drive 67 miles, multiply 67 by 8 and get 536.
So, he drives 536 miles in 5 hours
Answer: I think 402
Step-by-step explanation: I divided 804 to 4 and I got 201 then I added 201+201= 402 and each 4 hours he went 201 miles so if you add 201 and 201 you get 402 miles. Hope it helped!! :)

What is the fifth term of the geometric sequence whose first three terms are 486, 162, and 54?
a. 2
b. 3
c. 4.5
d. 6
e. 9
Answer:
6
Step-by-step explanation:
an = ar^(n-1)
a = first term
n = nth term
r = common ratio
r = r2 / r1 = r3 / r2
The first 3 terms are :
486, 162, and 54
Hence,
a = 486
r = 162 / 486 = 1/3
Hence ;
a5 = 486(1/3)^5 - 1
a5 = 486(1/3)^4
a5 = 486(1 / 81)
a5 = 486 * 1 / 81
a5 = 486 / 81
a5 = 6
The 5th term of the geometric progression will be ; 6
