Alex has 8 quarters six dimes and four nickels in his pocket what is the probability he will not select a quarter. How to give my the answer like 2/10
Explanation:
There are 8+6+4 = 18 coins, 18-8 = 10 of which aren't quarters.
10/18 = 5/9 is the probability of not selecting a quarter.
Trina ran 2 1/2 miles of Friday, 2 3/4 miles on Saturday and 3 mies on SUnday. The next week she ran the same amount. How far in miles did she run in two weeks?
Answer:
16 [tex]\frac{1}{2}[/tex] miles
Step-by-step explanation:
2 [tex]\frac{2}{4}[/tex] + 2 [tex]\frac{3}{4}[/tex] = 4 [tex]\frac{5}{4}[/tex] which equals 4 + 1 [tex]\frac{1}{4}[/tex] or 5 [tex]\frac{1}{4}[/tex]
5 [tex]\frac{1}{4}[/tex] + 3 = 8 [tex]\frac{1}{4}[/tex]
she ran 8 and one-quarter miles in the first week and if she ran the same amount the second week then we can add to get the answer:
8 [tex]\frac{1}{4}[/tex] + 8 [tex]\frac{1}{4}[/tex] = 16 [tex]\frac{2}{4}[/tex] or 16 [tex]\frac{1}{2}[/tex]

I need help on this pre-calculus function about domain and range.
Answer:
7
Step-by-step explanation:
X=?
Missing angle=?
Answer: 132
X = 180 - 47 +1
x=132
Answer:
x = 67, 133 degrees
Step-by-step explanation:
2x - 1 + 47= 180
2x + 46 = 180
2x (+ 46 - 46) = 180 - 46
2x = 134
2x/2 = 134/2
x = 67
2x - 1
2(67) - 1
134 - 1
133 degrees
Which term would be combined with the constant +2 in the expression -8x^2 + 3x +2?
Answer:
102(5x+2y)+3x+6y−10
Step-by-step explanation:
Terms is each part of an algebraic expression separated by a plus or minus sign.
As 2(5x +2y ) , 3x , 6y2(5x+2y),3x,6y and 1010 .
Factor is a product of two or more numbers, algebraic variables or algebraic expressions . 2(5x +2y )2(5x+2y) has two factors 22 and (5x +2y )(5x+2y) .
3x3x has two factors 33 and xx .
6y6y has two factors 66 and yy .
-10−10 has one factors
Coefficient is the numerical factor of a term that contains a variable.
2(5x +2y ) the factor is 22 .
3x3x the factor is 33 .
6x6x the factor is 66 .
-10−10 the factor is -10−10 .
Variable is a symbol, usually a letter, used to represent a number.
As xx and yy
Constant is a term without a variable.
As -10−10 .

HELP
To make an international telephone call you need the code for the country you are calling. The codes for country A, country B, and C are three consecutive integers
whose sum is 84. Find the code for each country.
Answer:
27, 28, 29
Step-by-step explanation:
If you divide 84 by 3, the quotient will be in the middle of the three integers. We get 28 from dividing 84 by 3, therefore our string of numbers are 27, 28, and 29.
From the graph of the function, determine the domain and the range.
Domain: (-2, 0) (0,5] Range: (-2,0] [2, 4]
Domain: [-2, 4] Range: (-2, 0] [2, 4]
Domain:(-2, 0) (0, 4) Range: (-2,5]
Domain: (-2, 4] Range: (-2, 0] [2, 4)
Hey there again! :)
This function is a piecewise function and it's different from previous question.
As you may notice, the graphs are separated and some of coordinate points are not a part of domain and range. That's why we have separate domain and range.
First, let's consider that line graph. The one that contains (-2,0) and (0,-2).
Our domain is the set of all x-values. Only (-2,0) is a closed dot. We use [ ] for closed dot and ( ) for opened dot.
Hence, the first domain is [-2,0)
Next, we find the range of line graph or line segment.
Range is the set of all y-values. Hence, the first range is (-2,0]
We are not done yet! We have to find the second domain and range, which is a curve graph.
From the curve graph, our first point starts from (0,4) and ends at (5,4)
Since (0,4) is an opened dot and (5,4) is a closed dot.
Therefore, the second domain is (0,5]
For the range, the minimum point is (3,2) and maximum point is (0,4) and (5,4). Use the y-coordinate to find range.
Hence, the second range is [2,4}
Gathering Both Domain and Range
First Domain is [-2,0)First Range is (-2,0]Second Domain is (0,5]Second Range is [2,4]Combine both domains and ranges.
Hence, the domain is [-2,0] U (0,5] and the range is (-2,0] U [2,4] or The First Choice
Let me know if you have any questions!

Each ride at the carnival requires 4 tickets to ride. Kate purchased 20 tickets and has
already ridden some rides.
Kate writes the expression 20 – 4r and Brian writes the expression 4(5 – 1) to
determine how many tickets Kate has left after riding some rides. Both expressions
are correct
Drag each description to explain each part of both expressions.
Step-by-step explanation:
In Kate's equation, 20 is the total number of tickets, 4 is number of tickets per ride, r is number of rides already ridden, and 4r is the number of tickets used
in Brian's equation, 5 is total number of rides Katie can ride and 5 - r is the number of rides left to ride

Answer:
See below.
Step-by-step explanation:
a. Choose any 3 non-collinear points on the plane. For example, plane R can be described as plane OSQ.
b. "Collinear" means points that lie on the same line. Example: M, N, P (note that the line these points are on does not lie in plane R)
c. [tex]\overrightarrow{NM}[/tex] and [tex]\overrightarrow{NP}[/tex]
d. There are many. Examples: O, N, Q, S. Not M. Not P.
solve for x…..…………………
Answer:
x = 11
Step-by-step explanation:
From the diagram, we find,
(2x - 16) + (x - 8) = 9
=> 2x - 16 + x - 8 = 9
=> 2x + x - 16 - 8 = 9
=> 3x - 24 = 9
=> 3x = 9 + 24
=> 3x = 33
=> x = 33/3
=> x = 11

The width of a rectangle is 2w and the length is (w + 5). The perimeter is 40 inches. What are the measurements of the rectangle
Answer:
Width = 2w , Length = w+5 , perimeter = 40
Perimeter of rectangle = 2 (Length + Width)
P= 2 (L + w)
40 = 2 [ (w+5) + (2w) ]
40 = 2 ( 3w+5)
40= 6w +10
6w= 40 – 10
6w= 30
w = 30/6
w = 5
Width = 2w = 2(5) = 10
Length = w + 5 = 5+5 = 10
