Ashleigh can choose from one of 6 different routes to get to work. The routes are listed below.
• Main St.
• Route 6
• Hilltop Drive
• Medical Avenue
• Highway 220
• Friendship Boulevard
If she chooses one route at random, what is the probability that she will choose either Hilltop Drive or Medical Avenue to get to work?
Answer:
1 /3
Step-by-step explanation:
Total Number of routes = 6
Probability = required outcome / Total possible outcomes
Probability of any one of the routes :
Required outcome / Total possible outcomes
Probability of choosing any one of the routes = 1/6
Hence,
Probability of choosing either Hilltop. Drive or medical avenue =
1/6 + 1/6 = (1 + 1) / 6 = 2 /6 = 1/3
In the following diagram, parallelogram ABCD contains triangle CED. Line CE and line ED intersect at point E. The measures of ∠CEA and ∠CDE are shown. What is the measure of x?______ degrees *
Answer:
∠x = 59°
Step-by-step explanation:
∠ECD = 52° because they are alternate angles and will be equal
∠x = 180° - 52° - 69° = 59° because the sum of the interior angles of a triangle = 180°

Two fifths of a number is 24.
what is the number?
Answer:
60
Step-by-step explanation:
half of 2/5 is 1/5 so half of 24 is 12.
since 12 is 1/5 of the number multiply 12 by 5 and you get 60.
The whole number will be 60 whose two fifths will be 24.
Given, Two fifths of a number is 24.
Writing in form of equation,
Let the whole number be x.
So, two fifth of x is 24.
[tex]\frac{2}{5} of x = 24[/tex]
[tex]\frac{2}{5} \times x = 24[/tex]
Apply cross multiplication,
[tex]x = \frac{24 \times 5}{2}[/tex]
x = 60.
Therefore the whole number is 60.

the lenght of an arc in a circle with diameter 10 inches is 1.25π inches. determine the measure of the arc.
Answer:
[tex]the \: angle \: is \: 0.25\pi[/tex]
Step-by-step explanation:
the arc length is equal to the radius x angle (in radians)
[tex]s=ra[/tex]
s= arc length, r= radius and a= the angle
solve for a ; a= s/r; a=
[tex]1.25\pi/5[/tex]
The measure of the arc is 0.25π.
Important information:
Diameter of a circle = 10 inches.Length of arc = 1.25πMeasure of arc:The formula for arc length is:
[tex]s=r\theta[/tex]
where s is the arc length, r is the radius and [tex]\theta [/tex] is the measure of arc in radian.
The diameter of a circle is 10 inches. So, the radius is 5 inches.
[tex]1.25\pi=5\theta[/tex]
[tex]\dfrac{1.25\pi}{5}=\theta[/tex]
[tex]0.25\pi=\theta[/tex]
Therefore, the measure of the arc is 0.25π.

Solve the following exponential equations
Answer:
x = 2, y = - 25
Step-by-step explanation:
(1)
note that 36 = 6² , then
[tex]6^{x}[/tex] = 6²
Since bases on both sides are equal then equate the exponents
x = 2
------------------------------------------
(2)
Using the rule of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
note that 25 = 5² , then
[tex]25^{11+3y}[/tex] = [tex](5^2)^{11+3y}[/tex] = [tex]5^{22+6y}[/tex]
Then
[tex]5^{5y-3}[/tex] = [tex]5^{22+6y}[/tex]
Since bases on both sides are equal then equate the exponents
22 + 6y = 5y - 3 ( subtract 5y from both sides )
22 + y = - 3 ( subtract 22 from both sides )
y = - 25

Five students participated in an Easter egg hunt. Ally snatched up one
quarter of all of the eggs. Brett only managed to get half of what Ally
found. Lee snagged six more than Brett. Jen ended up with half of Lee's
take, while Lisa snagged three times that. How many eggs were there in
total?
Answer:
There were a total of 72 Easter eggs.
Step-by-step explanation:
Since five students participated in an Easter egg hunt, where Ally snatched up one quarter of all of the eggs, Brett only managed to get half of what Ally found, Lee snagged six more than Brett, Jen ended up with half of Lee's take, While Lisa snagged three times that, to determine how many eggs were there in total, the following calculation must be performed:
Ally: 0.25X
Brett: 0.125X
Read: 0.125X + 6
Jen: 0.0625X + 3
Smooth: 0.1875X + 9
X - 0.25X - 0.125X - 0.125X - 0.0625X - 0.1875X = 0.25
0.25X = 6 + 3 + 9
0.25X = 18
Ally: 18
Brett: 9
Read: 15
Jen: 7.5
Smooth: 22.5
18 + 9 + 15 + 7.5 + 22.5 = X
72 = X
Thus, there were a total of 72 Easter eggs.

Label each statement as true or false regarding the zeros/roots of a quadratic function. The roots zeros of a quadratic function are the same as the factors of the quadratic function. The roots zeros are the spots where the quadratic function intersects with the y-axis. The roots zeros are the spots where the quadratic function intersects with the x-axis. There are not always two roots/zeros of a quadratic function,
Answer:
True, false, true, true.
Step-by-step explanation:
The roots zeros of a quadratic function are the same as the factors of the quadratic function. This is true because your roots are your factors—>(x-3) is a factor, x=3 is the root.
The roots zeros are the spots where the quadratic function intersects with the y-axis. No! Those are called y-intercepts!
The roots zeros are the spots where the quadratic function intersects with the x-axis. True. X-intercepts are your solutions. (x-3) graphed would the (3,0). That’s a solution.
There are not always two roots/zeros of a quadratic function, True. No solution would be when your quadratic doesn’t intersect the x-axis. One solution would be when your vertex would be on the x-axis. Two solutions is when your quadratic intersects the x-axis twice. Can there be infinite solutions? No. It’s either 0, 1, or 2 solutions.

Jazmin takes a ride share service home from the airport. The ride share service charges $5 as an initial cost to pick her up, and $2.25 for every mile to her final destination. Jazmin's ride home cost a total of $38.75. Write an equation to represent the situation. Let m represent the number of miles to her home.
Answer:
38.75 = 2.25 m + 5
Step-by-step explanation:
It is given that :
Jazmin took a ride share service from airport to home.
The total cost of the ride service from airport to home is = $ 38.75
The ride service charged an initial cost for picker Jazmin = $ 5
Cost of the ride service for every mile = $ 2.25 per mile
Let the number of miles = m
Therefore, the equation that represents the situation is :
38.75 = 2.25 m + 5
where, m represents the number of miles.

If y varies inversely with x, and y= 12 when x = 16, what is the constant of variation k?
Answer:
k = 192
Step-by-step explanation:
Given that,
y varies inversely with x. It can be written as :
[tex]y=\dfrac{k}{x}[/tex]
Where
k is the constant of variation
Put x = 16 and y = 12 in the above formula.
[tex]k=yx\\\\k=16\times 12\\\\k=192[/tex]
So, the value of the constant of variation is equal to 192.
