what is the answer to 2/5+5/10=

Answers

Answer:

[tex]\frac{2}{5\\}[/tex] + [tex]\frac{5}{10}[/tex]= [tex]\frac{9}{10}[/tex]

Step-by-step explanation:

Because this is not multiplication or diving you must find the same denominator, which is 10. Now, because 5/10 is already 10 I don't need to change that, but if you see that 2/5 does not have the denominator of 10. Then, I need to multiply 2 on the numerator and the denominator because 5(2) equals 10 and whatever is multiplied to the denominator has to be multiplied to the numerator. So. now the numerator is 4. Lastly, what you need to do is add them together. So, (2+5)=7 and the denominator is stays as 10 because it is addition. So, our final answer is 9/10

Answer:

  domain: (-4, -2) ∪ [-1, 4]

  range: (-5, 3)

Step-by-step explanation:

Domain

The domain is the horizontal extent of the graph. Here, it is comprised of two intervals. The left interval is open, as the function is not defined for x-values of -4 or -2. That interval is (-4, -2). The right interval is closed, as the function is defined for both x=-1 and x=4. That interval is [-1, 4]. The domain is the union of these two intervals.

  D: (-4, -2) ∪ [-1, 4]

__

Range

The range is the vertical extent of the graph. The left portion of the graph has a range from -5 to 3, but neither of those values is included in it. That is, the range is an open interval: (-5, 3).

The right portion of the graph has a range from 1 to 2, including both of those values. This interval is already included in the interval (-5, 3), so only one interval is needed to describe the range:

  R: (-5, 3)

goes up by 1 each time

The pattern of Jordan is that, she goes up by 1 , each time.

It is given that Jordan counts 53 ducks on a pond and then she counts 3 more by following a same pattern each time.

What is the pattern that she follows ?

What will be the value if we add 1 for 4 times.

The value will be 4.

The numbers Jordan counts are

50, 51 , 52 , 53 , 54 ,  55 , 56 , 57 , 58 , 59, 60

If we check

51 - 50 = 1

52-51= 1

.

.

.

60-59 = 1

and so on.

Every time we get a difference of 1 count.

Thus , the pattern followed by Jordan is that, she goes up by 1 , each time.

I believe you would have to subtract the given angle by the supplementary and complementary angle. For example:

1) S= 90-59=31 C= 180-59=121
2) S= 90-20=79 C= 180-20=160
3) S= 90-53=37 C= 180-53=127
4) S= 90-22.6=64.7 C= 180-22.6=157.4
5) S= 90-28=62 C= 180-28=152
6) S= 90-74=16 C= 180-74=106

Find the exact value of sin

Answers

Plug into the Sine subtraction formula which is sin(x - y) = sinxcosy - cosxsiny
So
First find the Cos of the values using a triangle and the Pythagorean theorem
Triangle X missing side =Sqrt(5^2 - 4^2) = 3
Triangle y missing side = sqrt(13^2 - 12^2) = 5
So we now plug it into the equation
(4/5)(5/13) - (3/5)(12/13)
Multiply
4/13 - 36/65 = -16/65

Answer:

2323

Step-by-step explanation:

Mental math means to find a way to do this problem in your head without using paper, pencil or a calculator.

The question says there are 23 classes and each class is to collect 101 items.

The equation would be 23 x 101.

To do this in your head real quick, make the numbers easier to multiply.

Make the 101 items 100.  That means you are telling each class to collect 1 less item or 23 less items total.

You can do this in your head real quick.  23 classes collecting 100 items is 2300 items.

You had each class collect 100 items instead of 101.  That mean you didn't collect 23 items.   So if you add those back in, you will get

2323 items.

Data for length of the tail (in millimeters) and age (in days) of tadpoles is entered into a statistics software package and results in a regression equation of ŷ = 15 - 1.5x.

What is the correct interpretation of the slope if the length of the tail is the response variable and the age is the explanatory variable?

Answers

Using the slope concept, it is found that the correct interpretation is that each day, the length decreases by 1.5 millimetres.

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which

m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.b is the y-intercept, which is the value of x when y = 0.

In this problem, the length of the tail, in millimetres, after x days, is given by:

[tex]y = 15 - 1.5x[/tex]

The slope is of [tex]m = -1.5[/tex], which means that each day, the length of the tail decreases by 1.5 millimetres.
