How many times smaller is 3 × 10^-8 than 6 × 10^-3?A.20,000,000

B.2,000,000

C.200,000

D.20,000

Answers

Answer 1
Answer: (6 * 10^(-3))/(3 * 10^(-8))=(6)/(3) * (10^(-3))/(10^(-8))=2 * 10^(-3-(-8))=2 * 10^(-3+8)=2 * 10^5= \n\n =2 00 ,000

The answer is C.

51. Q(3, 9), P(-1,5)
find the coordinates of the missing endpoint if P is the midpoint of NQ

Answers

X1= 3, Y1= 9
Midpoint formula= (?,?)= (x1+x2/2 , y1+y2/2)
-2= 3+? Making ?= -5
10= 9+? Making ?= 1
So your answer is (-5,1)= N

Final answer:

The coordinates of the missing endpoint, if P is the midpoint of segment NQ, are found using the formula N = 2P - Q. Substituting the given values into this formula, the coordinates of the missing point N are (-5, 1).

Explanation:

If point P is the midpoint of segment NQ, we can use the formula for finding the coordinates of the endpoint if we know the midpoint and one endpoint. The formula states:

To find the missing endpoint (in this case, point N), we use the formula: N = 2P - Q

Substituting the given values into the formula, we get:

N = 2(-1, 5) - (3, 9)

N = (-2, 10) - (3, 9)

N = (-5, 1)

So, the coordinates of the missing endpoint N are (-5, 1).

To become a member of an ice skating rink, you have to pay a $30 membership fee.The cost of admission to the rink is $5 for members, and $7 dollars for nonmembers. After how many visits to the rink is the total cost for members, including for membership fee, the same total cost for nonmembers?

Answers

30 = 5(m) + 7(n)

5(a) + 30 = 7(a)

(a) is the number of visits!

15 = (a) 

5(15) = 75 + 30 = 7(15) = $105

Decrease £1280 by 60%

Answers

Hi rainy here !!! so lets see lets set up your problem like this                              

X/1280 = 60%/100 so lets cross multiply

100 times X =100X

60 times 1280 = 76800

100X=76800 now lets divide each side by 100

100 divided by 100 = 0

76800 divided by 100 = 768

X=768 

So now we have to subtract to get the total amount so 1280 minus 768 = 512

512 is your answer :)

Hope I helped if u have any questions on how I did your problem feel free to message me or comment on my page bye !!!

Earyn owns French Twist Hair Salon. She charges $35 for a cut an $120 for a cut and color combo. Yesterday she had seven clients and earned $500. Let x represent only the clients that got a cut and y represent the clients that got a cut and color combo.Which of the following equations could be used to represent this situation.

y=7-x

x + y= 500

120x + 35y= 500

(35+120) (x + y)= 500

35x + 120y= 500

Answers

35x + 120x = 500
This is the correct equation because:
 x represents the clients that got a cut (at a cost of 35)
So the total profit she earned from just the cuts is 35 times the number of people for a cut
y represents the clients that got a cut and color (120)
So the total profit she earned from the cut/color is 120 times the # of people for cut/color
It is equal to $500 because thats how much Earyn earned!
I hope this helped

The ground temperature at Brigham Airport is 12 degrees Celsius. The temperature decreases by 6.8 degrees Celsius for every increase of 1 kilometer above the ground. What is the temperature outside a plane flying at an altitude of 5 kilometers?

Answers

Answer:

-22 degrees Celsius.

Step-by-step explanation:

Let x represent number of kilometers.

We have been given that the temperature decreases by 6.8 degrees Celsius for every increase of 1 kilometer above the ground. So temperature decreased in x hours would be -6.8x.

The ground temperature at Brigham Airport is 12 degrees Celsius. The temperature at an altitude of x kilometers would be 12-6.8x.

To find temperature outside a plane flying at an altitude of 5 kilometers, we will substitute x=5 in our expression as:

12-6.8(5)

12-34

-22

Therefore, the temperature outside a plane flying at an altitude of 5 kilometers would be -22 degrees Celsius.

-22 degrees Celsius should be the answer
6.8 times 5 is 34
since 34 is bigger than 12, you take 12 from 34 and add a negative sign, and that would be -22.
You can use a calculator if u want and is allowed too. :)
