What is the probability of choosing a number from 1 to 10 that is greater than 5 or even?
Answer:
3/10 or 30%
Step-by-step explanation:
The longest, yet easiest way to do this is to find all possible numbers that fit this scenario
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Even Numbers: 2, 4, 6, 8, 10
Greater Than 5: 5, 6, 7, 8, 9, 10
Now find common numbers in both categories
6,8, and 10
meaning the probability is 3/10 or 30%

Given f(x) = 2x + 5, find x when f(x) = 45
Step-by-step explanation:
f(x) = 2x + 5 = 45
2x + 5 = 45
2x = 45 - 5
2x = 40
x = 20
Answer:
f(x) = 2x + 5 = 45
2x + 5 = 45
5-25=2x
40=2x
x = 20

A family buys b boxes of frozen waffles each containing w waffles. Each week the family eats x waffles. Write an equation in terms b,w,x that represents the number of remaining waffles r, after 2 weeks
Answer:
r=b(w)-2x
Step-by-step explanation:
were solving for r so that is our end variable
sense we dont know how many boxes there are we just put b in the equation by itself, multiplying it with w since that represent the total number of waffles
b(w)
Ex: they buy 2 boxes and each box contains 24 waffles
b=2 and w=waffles
it then says each week they eat x amount of waffles, meaning its the same number for every week allowing us to multiply it with the number of weeks.
2x
Ex: say the family eats 10 waffles per week week, meaning x=10, well the we just multiply the 10 by the number of weeks
Answer: r = b(w) - 2x
The number of remaining waffles r, after 2 weeks is r=bw-2x.
Given that, a family buys b boxes of frozen waffles each containing w waffles.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The number of remaining waffles r, after 2 weeks.
Number waffles = Number of boxes × Number of waffles in each box
= b × w
= bw
Now, number of waffles left after 2 weeks = 2x
So, equation is r=bw-2x
Therefore, the number of remaining waffles r, after 2 weeks is r=bw-2x.

A railroad track follows a straight path from station A to station B. What is the distance traveled by the railroad track from station A to station B before completing its journey until station C? Distance travelled from station A to station C is 3x+4 and from station B to C is 6x-4.
Answer:
-3x + 8
Step-by-step explanation:
The railroad track moves in a straight path from station A to station B and then from station B to station C.
Let the distance from station A to station C be AC and the distance from station B to station C as BC while the distance from station A to station B be AB the following equation holds:
AC = AB + BC
Given the distance from station A to station C is 3x + 4 and from station B to C is 6x-4, Hence:
AC = 3x + 4 and BC = 6x - 4.
Using the line segment addition postulate:
AC = AB + BC
3x + 4 = AB + (6x - 4)
AB = 3x + 4 - (6x - 4)
AB = 3x + 4 - 6x + 4
AB = 3x - 6x + 4 + 4
AB = -3x + 8

A pool charges a membership fee of $40 for the summer and $1 for each visit. A different pool charges no membership fee but it costs $5 for each visit. How many visits would the two pools cost the same amount? A)40 visits B)10 visits C)5 visits D)they'll never cost the same amount
Answer:
B) 10 visits
Step-by-step explanation:
Let the number of visits be x.
Pool A cost: 1x + 40 = x + 40
Pool B cost: 5x
Set the two costs equal and solve for x.
x + 40 = 5x
Subtract 5x from both sides. Subtract 40 from both sides.
-4x = -40
Divide both sides by -4.
x = 10
Answer: B) 10 visits

At the beginning of the day the stock market goes down 50 1/2 points and stays at this level for most of the day. At the end of the day the stock market goes up 80 1/4 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
The change for the day is 29 3/4Step-by-step explanation:
In this problem, we are expected to calculate the change in the price of a particular stock
Given that the days high is 80 1/4
and also that the days low is 50 1/2
we can calculate the change by subtracting the days low from the days high
i.e 80 1/4- 50 1/2= 321/4-101/2= (321-202)/4= 119/4 = 29 3/4
hence the change for the day is 29 3/4
Also we can calculate the percentage change as
%change = (high-low)/low*100
%change= 80 1/4- 50 1/2/50 1/2= 29 3/4/50 1/2 *100
%change= 119/4*2/101 *100= 119/202*100= 0.589*100= 58.9%
%change= 58.9%

If m∠ABD = 70° and m∠CBD = 30°, then m∠ABC = ?
Answer:
40° or 100°.
Step-by-step explanation:
If Angle ABD = 70° and Angle CBD = 30° Angle ABC can be 70° + 30° or 70° - 30°.
angle ABC measures 100 degrees.
To find the measure of angle ABC, we can use the fact that the sum of the angles in a triangle is 180 degrees.
In triangle ABC , we have angle ABD measuring 70 degrees and angle CBD measuring 30 degrees.
Since angle ABD and angle CBD are adjacent angles, they add up to form angle ABC.
Therefore, we can calculate angle ABC as follows:
m ∠ ABC = m ∠ ABD + m ∠ CBD
m ∠ ABC = 70° + 30°
m ∠ ABC = 100 degrees
Thus, angle ABC measures 100 degrees.

Explanation:
The rule [tex](x,y) \to (-x,y)[/tex] has us flip the sign of the x coordinate from positive to negative (or vice versa). This applies a reflection over the y axis. For example, the point (5,6) moves to (-5,6).
Currently this shape is in quadrant 1. The quadrants start in the top right corner, and you move counterclockwise going to quadrants 2,3, and 4. Quadrant 2 is to the left of quadrant 1, and this is where all of the points end up after applying a reflection over the y axis.
