Based on the table, Phoenix has the highest temperature in January. Therefore, the correct option is option C among all the given options.
What is temperature?The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature. Thermometers are calibrated using a variety of temperature scales, which historically defined distinct reference points including thermometric substances.
The most popular scales are the Kelvin scale (K), which is mostly used for scientific purposes, the Celsius scale (°F), as well as the Celsius scale, which has the unit symbol °C. Based on the table, Phoenix has the highest temperature in January.

Review the proof. Which step contains an error
Step 2
Step 4
Step 6
Step 8
Answer: step 4
Step-by-step explanation:
Error in the proof starts with the first mistake done. The erroneous step in the proof is given by: Option B: Step 6.
How does sign changing works?Sign changing in equation does by multiplying -1 on both the sides.
So, if we had [tex]a + b = c[/tex]
Then, its signs are changed as:
[tex]-1(a + b) = -1 \times c\\-a -b = -c[/tex]
For the given case, the mistake occurred during transition from step 5 to step 6. Step 6 is wrong as when sign was changed, sin of cos(θ) remain same, which makes step 5 and step 6 not equal to each other.
The correct proof would be like:
[tex]\rm \cos(2x) = 1- 2\sin^2(x)\\Let\: 2x = \theta\\\\Then: x = \dfrac{\theta}{2}\\\\\cos(\theta) = 1 - 2\sin^2(\dfrac{\theta}{2})\\-1 + \cos(\theta) = -2\sin^2(\dfrac{\theta}{2})\\\\1 - \cos(\theta) = 2\sin^2(\dfrac{\theta}{2})\\\\\dfrac{1-\cos(\theta)}{2} = \sin^2(\dfrac{\theta}{2})\\\\\sin(\theta) = \pm \sqrt{\dfrac{1-\cos(\theta)}{2} }[/tex]
Thus, the erroneous step in the proof is given by: Option B: Step 6.

Chad and Eric left a 20% tip after having lunch at a restaurant. Chad's lunch cost $10.
Which equation can you use to find x, the cost of Eric's lunch?
Group of answer choices
A) 0.2(x + 10) = 5
B) 0.2x = 10 + 5
C) 0.2x + 5 = 10
D) 0.2x + 10 = 5
Answer:
The equation used to find x, the cost of Eric's lunch is [tex]\mathbf{0.2(x+10)=5}[/tex]
Option A is correct option.
Step-by-step explanation:
Chad and Eric left a 20% tip after having lunch at a restaurant.
Cost of Chad Lunch = $10
Let Cost of Eric's lunch = x
So, Total cost of Chad and Eric's Lunch = x+10
Now, they left a 20% tip
it means 20% of total cost of lunch
20% can be written as 0.2
So, 0.2 of total cost of lunch is tip of the meal
We can write: 0.2 of (x+10)
or 0.2(x+10)
Looking at options, considering $5 was the amount of tip, the final equation will be:
[tex]0.2(x+10)=5[/tex]
So, the equation used to find x, the cost of Eric's lunch is [tex]\mathbf{0.2(x+10)=5}[/tex]
Option A is correct option.
The numbers from 1 to 150, inclusive, are placed in a bag and a number is randomly selected from the bag. What is the probability it is not a perfect power (integers that can be expressed as $x^{y}$ where $x$ is an integer and $y$ is an integer greater than 1. For example, $2^{4}
Answer:
139/150
Step-by-step explanation:
Let's make a list of the perfect squares.
1 4 9 16 25 36 49 64 81 100 121 144
The probability that one of these is drawn is 12/150 = 4/50 = 2/25
Take out 1. So that means there are 11 perfect squares.
11/150 are your chances of getting a perfect square.
1 - 11/150 = 139/150 that you will not get a perfect square.
I would have included 1 in the perfect squares, but the question says not to so you can't.
If the question did not mean that 1 should be excluded, then the answer is 23/25

9(1017.36 in
9.254.34 in
Answer:
my answer is a bit different but kinda similar ig.
254.34in^2
Step-by-step explanation:
Radius = Diameter/2 18/2 = 9
Area of circle= pi(3.14) x r^2
A= (3.14) x 9^2
A= (3.14) x 81
A= 254.34in^2

Step-by-step explanation:
the radius of a bubble increases by 4%. Calculate the percentage increase in its (a) surface area (b) volume (to three significant figures )
Answer:
Step-by-step explanation:
Given that the radius of a bubble increases by 4%.
Let r be the radius of the spherical bubble, so the new radius of the sphere
[tex]R= r+0.04r = 1.04r\cdots(i)[/tex]
(a) Surface area of the bobble,
[tex]s=4\pi r^2[/tex]
So, the rate of increase of surface area = [tex]4\pi R^2 -4\pi r^2= 4\pi(R^2-r^2)[/tex]
The percentage change in the surface area [tex]= \frac {4\pi(R^2-r^2)}{4\pi r^2}\times 100[/tex]
By using equation (i)
The percentage change in the surface area = [tex]\frac {(1.04r)^2-r^2}{ r^2}\times 100[/tex]
[tex]=(1.04^2-1)\times 100[/tex]
=8.160%
Therefore, the percentage change in the surface area is 8.160%
(b) The volume of the sphere = [tex]4/3 \pi r^3[/tex]
So, the change in the volume = [tex]4/3 \pi R^3-4/3 \pi r^3[/tex]
Percentage change in the volume =
[tex]\frac {4/3 \pi R^3-4/3 \pi r^3}{4/3 \pi r^3}\times 100[/tex]
[tex]=(1.04^3-1)100[/tex] [by using equation (i)]
=12.486%
Therefore, the percentage change in the volume is 12.486%.
