Given:
Morning Temperature = 15 degrees, Afternoon Temperature = 30 degrees
Morning Temperature = 20 degrees, Afternoon Temperature = 40 degrees
Morning Temperature = 26 degrees, Afternoon Temperature = 52 degrees
To find:
The ratio of the afternoon to morning.
Solution:
Taking any one pair of morning and afternoon temperature, we can find the ratio.
Morning Temperature = 15 degrees
Afternoon Temperature = 30 degrees
[tex]\text{Ratio}=\dfrac{\text{Afternoon Temperature}}{\text{Morning Temperature}}[/tex]
[tex]\text{Ratio}=\dfrac{30}{15}[/tex]
[tex]\text{Ratio}=\dfrac{2}{1}[/tex]
[tex]\text{Ratio}=2:1[/tex]
Therefore, the correct option is C.
Answer:
C
Step-by-step explanation:
Can someone please help and solve
Answer:
C: x+y=27 and y=6+2x
Step-by-step explanation:
First part: If the sum of the two is 27, then it means that it is x + y = 27, because sum means addition.
Second part: The larger number (y) is 6 more than twice the smaller number (x). Twice a number means that it is that number multiplied by x, so it is 2x. 6 more means we add 6 to it so the second equation is y=6+2x.

The speed of sounds in water is 1.46 x 10^3 meters per second. The speed of sound in air is 3.31 x 10^2 meters per second. How much faster does sound travel in water than it air?
Answer:
Hey there!
1.46x10^3-3.31x10^2
14.6x10^2-3.31x10^2
11.29x10^2
1.129x10^3
J is the correct answer.
Hope this helps :)
The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.
Speed :The speed is the distance travelled per unit of time by a sound wave
Given informationSpeed of sound in water is [tex]1.46 \cdot 10^3[/tex]
Speed of sound in air is [tex]3.31 \cdot 10^2[/tex]
To find how much faster does travel , we need to subtract the speed
To subtract we need to make the exponents same
[tex]1.46 \cdot 10^3\\14.6 \cdot 10^2[/tex]
Now we subtract ,
[tex]14.6- 3.31= 11.29\\\\11.29 \cdot 10^2\\1.129 \cdot 10^3[/tex]
The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.

express sin110 as ratio of acute angle
Answer:
sin70°
Step-by-step explanation:
Given sin110° where 110° is an obtuse angle in the second quadrant.
The related acute angle in the first quadrant is 180° - 110° = 70°
Thus
sin110° = sin70°

what's the probability of pulling two red cards in a row from a deck of cards?
Hey there! I'm happy to help!
Let's say that we don't have jokers. In that case, there are 52 cards, and half of them are red (so 26 are red). The probability of pulling a red card once is 1/2 since half the cards are red.
If we pick one out, there are only 51 total cards left and 25 red cards. So, the probability of picking one again would be 25/51.
We multiply the probabilities of these two events to find the probability of them both happening.
1/2×25/51=25/102
The probability of picking two red cards in a row is 25/102 or around 24.5%.

4. [tex]2=-\frac{1}{3}x[/tex] Addition property of equality
5. -6 = x Multiplication property of equality
6. x = -6 Symmetric property
Answer:
To get from step 1 to step 2, apply the distributive property to eliminate the parentheses.
To get from step 2 to step 3, combine like terms on the right side of the equation.
To get from step 3 to step 4, apply the addition property of equality to isolate the variable term.
To get from step 4 to step 5, apply the multiplication property of equality to isolate the variable, x.
To get from step 5 to step 6, apply the symmetric property to rewrite the equation with the variable on the left side.

A bakery sells loaves of handmade French bread for $6 each and loaves of multigrain
bread for $8 each. The bakery eams, on average, $240 in revenue per day from the
sale of the French and multigrain breads.

Alex and leanardo went to the movies a drink cost $4.00 each and a bag of popcorn cost $ 5.00 each how many would they spend of they bouth 2 drinks and 2 Bags of popcorn
If Alex and Leonardo are both buying two bags of popcorn and drinks then the overall price would be $18.00.
$4.00 + $4.00 = $8.00 + $5.00 + $5.00 = $18.00
Therefore, they would spend 18 dollars.

Find the area of the given region using any method.
The best method would certainly be integration :)
The area is given by the integral,
[tex]\displaystyle\int_0^2\frac{\mathrm dx}{9-x^2}[/tex]
We can split up the integrand into partial fractions:
[tex]\dfrac1{9-x^2}=\dfrac16\left(\dfrac1{3-x}+\dfrac1{3+x}\right)[/tex]
Then the area is
[tex]\displaystyle\frac16\int_0^2\left(\frac1{3-x}+\frac1{3+x}\right)\,\mathrm dx[/tex]
[tex]=\dfrac16(-\ln|3-x|+\ln|3+x|)\bigg|_0^2[/tex]
[tex]=\dfrac16\left((\ln5-\ln1)-(\ln3-\ln3)\right)=\boxed{\dfrac{\ln5}6}[/tex]

After 8 hours of snow, the temperature had changed by a total of -16 degrees. What was the average change in temperature each hour while it was snowing?
Answer:
-2 degrees
Step-by-step explanation:
Divide -16 by 8:
-16/8
= -2
So, the average change in temperature each hour was -2 degrees.
The average change of weather dropped 2 degrees for every hour is snowed.
Here,
After 8 hours of snow, the temperature had changed by a total of -16 degrees.
We have to find the average change in temperature in each hour.
What is Average?
Average is the middle value of the given sets of values.
Now,
After 8 hours of snow, the temperature had changed by a total of -16 degrees.
Hence, The average change in temperature in each hour = -16 ÷ 8 = -2
Therefore, The weather dropped 2 degrees for every hour is snowed.
