A speed skater completes a 500 meter race in 40 seconds. A cheetah runs 260 meters in 10 seconds.How do their speeds compare

Answers

Answer:

25:26

Step-by-step explanation:

You mean the ratio?

Let's simplify the speed skater first. 500 meter in 40 second to x meter in 1 second. 500/40=12.5 meters per seconds

Cheetah:260/10=26 meters per seconds

Let's make this into a integer

12.5*2=25

(-6,-3) and (-1,x)=13 find the value of A

Answers

Distance between two point can be calculated by the equation:

D=sqrt((x2-x1)^2+(y2-y1)^2)
Then,
13=sqrt((-1-(-6))^2+(x-(-3))^2)
We can square both sides to get rid of the square root,
169=(-5)^2+(x-(-3))^2
169-25=(x-(-3))^2
144 =(x-(-3))^2
By taking the square root in both sides, then
12=x+3
In this case,
X=12-3=9
(-6-3) = -9, (-1,x)=13 : x=-13

A spinner with 12 equally sized slices has 5 yellow slices, 3 blue slices, and 4 red slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a yellow or blue slice?

Answers

the answer is 8/12 or 66.666% for the spinner landing on blue or yellow

The probability that the dial stops on a yellow or blue slice will be 0.6667.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

A spinner with 12 similarly measured cuts has 5 yellow cuts, 3 blue cuts, and 4 red cuts. The dial is turned and stops on a cut indiscriminately.

The total number of the event is given as,

Total events = 5 + 3 + 4

Total events = 12

The probability that the dial stops on a yellow or blue slice will be given as,

P = 3 / 12 + 5 / 12

P = 0.25 + 0.4167

P = 0.6667

The probability that the dial stops on a yellow or blue slice will be 0.6667.

FOIL method

x^2+6x-27=0

Find the common numbers that multiply to 27 that will also equal 6.

(27x6) or (9x3)

the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.

then FOIL them

FIRST:  x*x=x^2

OUTSIDE: x*-3=-3x

INNER: 9*x=9x

Step-by-step explanation:

55x + 10 = 230

=> 55x = 220

=> x = 4

Therefore, x = 4.

Hoped this helped.

Answer:

x= 4

Step-by-step explanation:

solving equation step-by-step.

55x + 10 = 230

Subtract 10 from both sides.

55x + 10 − 10 = 230 − 10

55x = 220

Divide both sides by 55.

55x/55 = 220/55

x= 4

Answer: See the diagram below

==========================================================

Explanation:

She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.

---------------------

For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)

|48-58| = 10|54-58| = 4|57-58| = 1|62-58| = 4|69-58| = 11

This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.

---------------------

The last thing to do is find the mean of the set {10,4,1,4,11}

add: 10+4+1+4+11 = 30

divide by five: 30/5 = 6

The mean absolute deviation (MAD) is 6

This represents the average distance each data value is from the mean.  The MAD tells us how spread out the data is. It's similar to the standard deviation.

Solve the equation: 6(x-2) -2x = 4x *
1 point
x= -12
x = 0
-12=0 no solution

Answers

Distribute 6
6x-12 - 2x =4x
Combine like terms
4x - 12 = 4x
Subtract 4x from both sides
-12=0 no solution
-12/0 that means it’s no solution (it’s pretty much means that there isn’t a correct answer for it) hope that helps!

Answers

Answer:

The number line is divided by 6ths.

Step-by-step explanation:

There are 6 equally sized spaces between 0 and 1 on a number line. By definition of a fraction, a quantity is divided upon a number of equal parts in which can be expressed as the number of parts divided by the total number of parts. Therefore, the numerator in this case will be how many of the 6 parts are there at a certain point; the denominator will be 6, since there are 6 total, equal parts. In this case, think of the fraction as a distance traveled from 0 to 1 in 6 parts; the numerator is how far is traveled, and the denominator is the total travel distance. Point A is located at 1/6, since it is 1 out of the 6 pieces traveled. Point D would be at 5/6 because it has traveled 5 out of the 6 distances.

Point A is at

29 inches - This is the only one that does not work.

30 inches - We can use 5 of the 6 inch trains, so this is possible.

31 inches - We can use 4 of the 6 inch trains and 1 of the 7 inch trains, so this is possible.

32 inches - We can use 3 of the 6 inch trains and 2 of the 7 inch trains, so this is possible.

33 inches - We can use 2 of the 6 inch trains and 3 of the 7 inch trains, so this is possible.

The first term is, 2d2 its coefficient is 2 .
The middle term is, -3d its coefficient is -3 .
The last term, "the constant", is -2

Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4

Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .

-4 + 1 = -3 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
