Answer:

Step-by-step explanation:

lets say 6 times 6 =36

3 is a half of six so if you

      6x6=36

     3x6=18

Answer:

Step-by-step explanation:

Work out the Mean,

Then for every number, subtract the Mean and square the result.

Then work out the mean of those squared differences

and then take the square root of that.

can you say me from which cource is this

Answer:

Step-by-step explanation:

A-B = 4–2 = 2 (age difference between A and B). IF A = 44,. B = A - 2 = 44 - 2 = 42 years old.

Answer:

39 years old

It could be;

10 ÷ 1/2 = 5

Age difference= 10 - 5= 5 years

So, 44 - 5 = 39 years old

Answer:

.052

Step-by-step explanation:

Answer:

Triangle A) acute

Triangle B) right

Triangle C) obtuse

Triangle D) obtuse

Step-by-step explanation:

Any triangle less than 90° is acute.

Triangles at exactly 90° are right triangles.

Any triangle more than 90° are called obtuse.

Answer:

20

Step-by-step explanation:

we can set up the equation like this:

n/4 + 2 = 7

subtract 2 from both sides

n/4 = 5

multiply 4 to both sides and you get...

n = 20

Answer:

Percent:

There are many formulas for percentage problems. You can think of the most basic as X/Y = P x 100. The formulas below are all mathematical variations of this formula.

X and Y are numbers and P is the percentage:

Find P percent of X

Find what percent of X is Y

Find X if P percent of it is Y

Mixture:

Solving a percent mixture problem can be done using the equation Ar = Q, where A is the amount of a solution, r is the percent concentration of a substance in the solution, and Q is the quantity of the substance in the solution.

Proportion:

Many "proportion" word problems can be solved using other methods, so they may be familiar to you. For instance, if you've learned about straight-line equations, then you've learned about the slope of a straight line, and how this slope is sometimes referred to as being "rise over run". But that word "over" gives a hint that, yes, we're talking about a fraction. And this means that "rise over run" can be discussed within the context of proportions.

6/4=1.5=14*1.5=21

21 minutes

Answer:

6

Step-by-step explanation:

Because J is the midpoint of KL, it means that KJ ans JL are equal.

Think about it like this:

Hope this helps!

Step-by-step explanation:

the midpoint of a line splits the line into 2 equally long parts.

therefore, JI must be equally long to KJ.

x = 6

and with KJ = 6 and JI = 6, then KI = KJ + JI = 6+6 = 12

Answer:

A: -41/9

Step-by-step explanation:

Substitute the point (4, -5) and slope -1/9 into the equation y = mx + b.

-5 = -1/9(4) + b

-5 = -4/9 + b

Solve for b:

b = -41/9

Our equation: y = -1/9(x) - 41/9

Answer:

  56 mph, 26 mph

Step-by-step explanation:

The trains are separating at the rate of (205 mi)/(2.5 h) = 82 mi/h. If we let s represent the speed of the slower train, then that sum of their speeds is ...

  s + (s+30) = 82

  2s = 52 . . . . . . . . . . subtract 30

  s = 26 . . . . . . . . . divide by 2

  s +30 = 56 . . . the speed of the other train

The speeds of the two trains are 56 mph and 26 mph.

Answer:

61

Step-by-step explanation:

So basically you separate the numbers like 1 1 1 1 0 1, and time 2 while having the number of numbers as the exponent decreasing. Like this, 1x2^5+1x2^4+1x2^3+1x2^2+0x2^1+1x2^0. Then figure it out and it would be 32+16+8+4+0+1=61. If don't understand, look at the picture below

Step-by-step explanation:

Answer: A, A, C

Step-by-step explanation:

Educated Guess because none of them are going to be zero so it's either A or C but the point has a negative y so to plug it all in all of them have to be negative ex. -1 + -1 + -1 =-3

the x is -1 so both have to be negative in order to get -3
