a = 8.5

b = 4.5

Step-by-step explanation:

let 2 number be a ,b

a + b = 13  (1)

a - b = 4    (2)

squared.
Find the missing side.

Answers

Answer:

x = 10 units

Step-by-step explanation:

The formula for the area of a triangle of base x and height h is A = (1/2)(x)(h).

Here A = (1/2)(x)(8) = 40, so 8x = 80 and x = 10 units

If we look at this triangle we can see the straight line (the height). We want to use the height to figure out the side? Well divide 40 with the height (8). And now you get 5(cause 5*8 is 40. duh)

A jar contains 50 marbles, 21 are blue, 15 are yellow, and the rest are red. What is the probability that you pick out a blue marble?

Answers

Answer:

The probability of drawing a red marble = 2/5. The probability of drawing a blue marble is now = 1/4. The probability of drawing a red marble = 2/5.

Step-by-step explanation:

Answer:

42%

Step-by-step explanation:

There are 21 blue marbles out of the 50. Divide 21 with 50:

21/50 = 0.42

Next, change the decimal to a percentage. To do so, move the decimal point to the right two place values and slap a percentage sign onto it:

0.42 = 42%

42% is your probability of picking a blue marble.

Answers

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 3

Step-by-step explanation:

A recursive formula allows a term in the sequence to be found from the previous term by adding the common difference to it.

Here d = 5 - 8 = - 3, thus

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 3 with a₁ = 8 ← recursive formula

What is the volume of the right rectangular prism, in cubic centimeters? A prism has a length of 4 centimeters, height of 9 centimeters, and width of 3 centimeters. cubic centimeters

Answers

The formula for volume is V = lwh

This means that the volume is equal to the length times the width times the height.

Multiply the three numbers for your answer.

Length = 4, width = 3, height = 9

lwh = 4cm X 3cm X 9cm = 12cm^2 X 9cm = 108cm^3

And there you have it! Your final answer is 108 cm^3 OR 108 cubic centimeters!

I do not mean to scare you, but this is the most basic volume formula! As you encounter different 3D shapes, the formulas will change!

The volume of the given rectangular prism is 108 cubic centimeters.

What is a rectangular prism?

A rectangular prism is a three-dimensional solid shape with six faces that including rectangular bases. A cuboid is also a rectangular prism. The cross-section of a cuboid and a rectangular prism is the same. Volume of a rectangular prism = Area of a base × Height.

Given that, a prism has a length of 4 centimeters, height of 9 centimeters, and width of 3 centimeters.

We know that, the volume of a rectangular prism = Length×Breadth×Height

= 4×3×9

= 108 cubic centimeters

Therefore, the volume of the given rectangular prism is 108 cubic centimeters.

Solve the following inequality in two ways and make a claim as to which
method is more efficient.
1/4 (8n - 12) < n + 2

Answers

Answer:

The solution of the given inequality  n < 5

Step-by-step explanation:

Explanation:-

Given inequality

                     [tex]\frac{1}{4} (8 n -12 ) < n +2[/tex]

Step(i):-

 Cross multiplication '4' we get

                    8 n - 12 < 4 ( n +2)

                    8 n - 12 < 4 n + 4×2

                    8 n - 12 < 4 n +8

      Subtracting  '4 n ' on both sides, we get

                 8 n - 4 n - 12 < 4 n - 4 n +8

                 4 n - 12  <  8

Step(ii):-

Adding ' 12 ' on both sides , we get

                4 n -12 + 12 < 8 + 12

                               4 n < 20

Dividing "4' on both sides , we get

                                 n < 5

The solution is n < 5

Conclusion:-

The solution of the given inequality  n < 5

What is most likely reason why the author shows sunshine behind the boy in this graphic Modify your "Star Search" program to read 100 scores from a text file, then execute the "Star Search" algorithm (drop the lowest and highest scores, then average the rest) and display the result, with three digits after the decimal point. As per the Star Search specifications, only scores from 0 - 10 will be accepted. Any score that is outside that range is to be rejected, and is not included in the average. That means that invalid scores can't be the high or low scores either.
