Answer:
B. 11 1/4
Step-by-step explanation:
8 3/4 + 2 2/4 = 11 1/4
We want to sum two mixed numbers.
The correct option is D: 11 1/4
A mixed number is a number that is separated into a whole part and a rational part.
Here we want to sum:
(8 3/4) + (2 1/2)
This can be written as:
8 + 3/4 + 2 + 1/2
Now we group the whole numbers and we group the rational numbers:
8 + 3/4 + 2 + 1/2 = (8 + 2) + (3/4 + 1/2) = 10 + (3/4 + 1/2).
To perform the sum of the rational numbers, we can write:
1/2 = 2/4
Then we have:
10 + (3/4 + 1/2) = 10 + (3/4 + 2/4) = 10 + 5/4 = 10 + 4/4 + 1/4 = 11 + 1/4
Then we can see that the correct option is D.

Solve for the value of z.
Answer:
13°
Step-by-step explanation:
2z + 5° + 5z - 6° = 90° { being complementary angles }
7z = 90° + 1°
7z = 91°
z = 91° / 7
z = 13°

A jar contains 38 red marbles numbered 1 to 38 and 38 blue marbles numbered 1 to 38 a marble is drawn at random from the jar
Answer:
[tex]P(Red) = 0.50[/tex]'
[tex]P(Odd) = 0.50\\[/tex]
Step-by-step explanation:
Given
[tex]Red = 38[/tex]
[tex]Blue = 38[/tex]
Required (Missing part of the question)
(a) The marble is red. (b) The marble is odd-numbered
Solving (a): Probability of Red.
This is calculated as:
[tex]P(Red) = \frac{Red}{Total}[/tex]
[tex]P(Red) = \frac{38}{38+38}[/tex]
[tex]P(Red) = \frac{38}{76}[/tex]
[tex]P(Red) = 0.50[/tex]
Solving (b): Probability of Odd
Since each marble type is numbered 1 to 38, then half of it are odd.
i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.
So, the probability of odd is:
[tex]P(Odd) = \frac{Odd}{Total}[/tex]
[tex]P(Odd) = \frac{19+19}{38+38}[/tex]
[tex]P(Odd) = \frac{38}{76}[/tex]
[tex]P(Odd) = 0.50\\[/tex]

Step-by-step explanation:
For each of the following situations, explain why the combinations rule or the permutations rule should be used. (a) Determine the number of different groups of 5 items that can be selected from 12 distinct items. Use the permutations rule, since the number of arrangements within each group is of interest. Use the combinations rule, since the number of arrangements within each group is of interest. Use the permutations rule, since only the items in the group is of concern.
Answer:
Use the combinations rule, since the number of arrangements within each group is of interest.
Step-by-step explanation:
Arrangments rule:
Number of items to be arranged is the same as the number of places.
Permutations formula:
Number of items to be arranged is different of the number of places, and the order in which the items are placed is important(AB and BA are different outcomes).
Combinations formula:
Number of items to be arranged is different of the number of places, and the order in which the items are placed is not important(AB and BA are the same outcomes).
In this question:
5 items from a set of 12. The order in which the items are chosen is not important(for example, a book and a pencil would be the same as a pencil and a book). So the combinations formula is used, and the correct option is given by:
Use the combinations rule, since the number of arrangements within each group is of interest.

(9x-4)°
(3x+ 14)°
solve for x=
don’t understand how to find the answer
Answer:
x=3
Step-by-step explanation:
Simplifying
9x + -4 = 3x + 14
Reorder the terms:
-4 + 9x = 3x + 14
Reorder the terms:
-4 + 9x = 14 + 3x
Solving
-4 + 9x = 14 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-4 + 9x + -3x = 14 + 3x + -3x
Combine like terms: 9x + -3x = 6x
-4 + 6x = 14 + 3x + -3x
Combine like terms: 3x + -3x = 0
-4 + 6x = 14 + 0
-4 + 6x = 14
Add '4' to each side of the equation.
-4 + 4 + 6x = 14 + 4
Combine like terms: -4 + 4 = 0
0 + 6x = 14 + 4
6x = 14 + 4
Combine like terms: 14 + 4 = 18
6x = 18
Divide each side by '6'.
x = 3
Simplifying
x = 3
Answer:
x = 3Explanation:
Write your equation
(3x + 14) = (9x - 4)Subtract 9x from both sides
3x + 14 − 9x = 9x − 4 − 9x
−6x + 14 = −4
Subtract 14 from both sides
−6x + 14 − 14 = −4 − 14
−6x = −18
Divide both sides by -6
−6x / -6 = −18 / -6
x = 3[ zyxx ]
