Answer:

1 9/10

Step-by-step explanation:

Rewriting our equation with parts separated

1+1/2+2/5

Solving the fraction parts

1/2+2/5=?

Find the LCD of 1/2 and 2/5 and rewrite to solve with the equivalent fractions.

LCD = 10

5/10+4/10=9/10

Combining the whole and fraction parts

1+9/10= 1 9/10

OR

Solution by Formulas

Convert any mixed numbers to fractions.

Then your initial equation becomes:

3/2+2/5

Applying the fractions formula for addition,

<u>(3×5)+(2×2)</u>

      2×5

= <u>15+4</u>

     10

= 19/10

Simplifying 19/10, the answer is

1 9/10

Hope this helps!

You can change the denominator to 10 which will get you to 55/10 + 4/10. You can add these two together to get 59/10

Which point should be removed for the graph to represent a table of equivalent ratios?
vodomira [7]
<h3>Answer:  D.   (5,15)</h3>

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

Explanation:

As the graph shows, three of the four points are on the same line. That line being y = 5x. This line has slope 5 and y intercept 0.

The point not fitting this pattern is the point (5,15), so that is the final answer.

For the other three points, note that the jump from x to y coordinate is "times 5". For example, y = 5x = 5*2 = 10 for point A. In contrast, point D has a jump of "times 3" when going from x to y.

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

Alternatively, you can divide each y coordinate by its corresponding x coordinate.

  • For choice A, we have y/x = 10/2 = 5
  • Choice B has y/x = 15/3 = 5
  • Choice C has y/x = 20/4 = 5

All results are 5 so far. Choice D doesn't follow the trend and instead has y/x = 15/5 = 3. This is another way to show that choice D is the answer.

Name the postulate or theorem you can use to prove the triangles congruent.
Maru [420]

Answer:

You can use the ASA Postulate to prove the Angle-Angle-Side Congruence Theorem. A flow proof is shown below. If two angles and a nonincluded side of one triangle are congruent to two angles and the corresponding nonincluded side of another triangle, then the triangles are congruent.

Is the number of free dash throw attempts before the first shot is madea discrete random​ variable, a continuous random​ variabl
mafiozo [28]

Answer:

a)Discrete random variable

Step-by-step explanation:

A discrete random variable is a variable which can only take a countable number of values, it means only take values in the natural numbers.

A continuous random variable is a random variable where the data can take infinitely many values; the random variable take values in the real numbers

Then the number of free throw attempts before the first shot is a discrete random variable because these can be counted with the natural numbers.
