On a math test, Ana writes 9 as the solution to 327.
a. Find the correct solution.
b. What error did Ana likely make on the test?
Answers
Considering the cube root of 27, we have that:
a) The correct solution is of 3.
b) The error that Ana likely made is that she considered the cube root as the number that is multiplied by 3 to get a result of 27, not the number that is elevated to three.
What is the problem?
The question is that Ana wrote 9 as a solution to the cube root of 27.
The cube root of a number is the number that is elevated by 3 to reach the number, for example:
1³ = 1, hence the cube root of 1 is of 1.2³ = 8, hence the cube root of 8 is of 2.3³ = 27, hence the cube root of 27 is of 3.From the last bullet point, we get the correct answer for item a.
For item b, we have that 9 x 3 = 27, hence the error that Ana likely made is that she considered the cube root as the number that is multiplied by 3 to get a result of 27, not the number that is elevated to three.

Select all of the following graphs which represent y as a function of x?
Answers
Using the concept for a relation to represent a function, it is found that graphs 2, 3, 4 and 5 are functions.
When does a relation represents a function?A relation represents a function when it value of the input is associated to only one value of the output.
On a graph, it means that each value of x has only one equivalent value of y, that is, there are no vertically aligned points.
In this problem, we have that:
The first graph, which maps the circle is not a function, as there are multiple values of x associated with two values of y, hence generating vertically aligned points.The last graph, below the constant line, also has values of x such as x = 0 mapped to two values of y(y = 1 and y = -2 for x = 0), hence it also is not a function.All the other graphs are functions.

Answer is x=11
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x−8)+11=17
(2)(x)+(2)(−8)+11=17(Distribute)
2x+−16+11=17
(2x)+(−16+11)=17(Combine Like Terms)
2x+−5=17
2x−5=17
Step 2: Add 5 to both sides.
2x−5+5=17+5
2x=22
Step 3: Divide both sides by 2.
2x/2=22/2

the difference between any two consecutive numbers in the list a,b,c,d,e is the same . If b = 5.5 and e = 10, what is the value of a
Answers
Answer:
a = 4
Step-by-step explanation:
You are given an arithmetic sequence with second term 5.5 and fifth term 10. You want to know the first term.
Common differenceThe 2nd term will have 3 times the common difference added to it to make the 5th term. Then that difference can be found from ...
5.5 +3d = 10 . . . . using 'd' for the common difference
3d = 4.5
d = 1.5
First termThe second term (a2) is obtained by adding the common difference (d) to the first term (a1):
a2 = a1 +d
5.5 = a1 + 1.5
4.0 = a1
The value of 'a' is 4.
__
Additional comment
The 'd' we're using here to represent the common difference is not to be confused with the 'd' in the problem statement that represents the fourth term of the list.
The fact that adjacent list members have the same difference is what tells you this is an arithmetic sequence. In terms of the problem statement, you have ...
{a, b, c, d, e} = {4, 5.5, 7, 8.5, 10}
Here, we have used the more common notation for elements of an arithmetic sequence.

The average amount of money spent by students in the cafeteria last week was $2.75. The actual amount spent varied by no more than $0.50. Write and solve an absolute value inequality to represent the range of possible amounts.
Answers
Answer:
Step-by-step explanation:
Last week, the typical amount of money spent by kids in the cafeteria ranged from $2.25 to $3.25.
What is Equation?Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right are shown to be equal in reference to one another. LHS = RHS (left hand side = right hand side) appears in all mathematical equations.
A mathematical equation can have many different components, such as coefficients, variables, operators, constants, terms, expressions, and an equal sign. An "=" symbol, as well as terms on both sides, are required when writing an equation.
Given:
Average amount spend = $2.75
Let x be the average dollar amount that students spend.
Then, the equation can be
|x - 2.75| = 0.5
Now, we have two values one is positive and another is negative
x - 2.75 = 0.5 or -(x - 2.75) = 0.5
x = 3.25 or x = 2.25
Hence, Last week, the typical amount of money spent by kids in the cafeteria ranged from $2.25 to $3.25.

For ΔDEF, Where e=52, f=41 and ∠F=48°. Find all the possible ∠E to the nearest degree.
The possible ∠E to the nearest degree is ∠E=70°
Given that,
ΔDEF with e=52 and f=41 sides of the triangle.
Angle ∠F=48°.
We have to find ∠E=?
By using the Law of sine
The relationship between the sides and angles of non-right (oblique) triangles is known as the Law of Sines. It simply states that for all sides and angles of a given triangle, the ratio of the length of a side to the sine of the angle opposite that side is the same.
If triangle ABC are there with sides a, b, and c then Law of sine is
[tex]\frac{a}{SinA} =\frac{b}{SinB} =\frac{c}{SinC}[/tex]
Now, in the given triangle we have e and f sides so we take
[tex]\frac{SinE}{e}=\frac{SinF}{f}\\[/tex]
Substituting the values of e, f and F
We get,
[tex]\frac{SinE}{52}=\frac{Sin48^\circ}{41}\\ SinE=\frac{Sin48^\circ}{41}\times52\\SinE=\frac{52}{41} \times Sin48^\circ\\SinE=1.268\times 0.743\\SinE=0.942\\E=Sin^{-1}(0.942)\\[/tex]
∠E=70°

Solve the inequality 3/4q - 2/3q < 5/12q - 1/12 and write the solution in interval notation?
Answers
Solution of the inequality is q> 1/4 and in interval notation is (1/4 , ∞ ).
According to the question we have been given the inequality that is
3/4q - 2/3q < 5/12q - 1/12
Solving the equation step by step we get
First simplifying 3/4q - 2/3q which will get q/12
Therefore, q/12 < 5/12q - 1/12
moving all the terms with q on the left hand side we get
q/12 - 5/12q < -1/12
(q-5q)/12 < -1/12
-4q/12 < -1/12
multiplying both sides by 12 we get
-4q/12 * 12 < -1/12*12
-4q < -1
multiplying -1 both sides we get

A car is traveling at 55 miles per hour. Use dimensional analysis to convert
the car's speed to feet per minute.
5,280 feet in 1 mile?
Answers
The car's speed to feet per minute is 80.67ft per second.
What is speed?
Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.Speed is a way to gauge how rapidly something is happening, moving, or moving swiftly. The speed of a car being driven at 45 mph serves as an illustration. A person cleaning a room in 10 minutes is an illustration of speed. Speed can be compared to how swiftly a jaguar moves.1 mile = 5280 feet
so 55 miles = 55*5280 = 290,400ft
there are 60 seconds in 1 minute and 60 minutes in 1 hour
so 1 hour = 60*60 = 3600 seconds
55mile/1hour = 290400ft/3600 seconds = 80.67ft per second

What is the equation of the parabola with focus (0,7) and directrix y = 1?
Answers
The equation of the parabola with the given focus and directrix is x² = 12( y - 4 ).
What is the equation of the parabola with the given focus and directrix?Since the directrix y = 1, it shows it is vertical, so we use the equation of the parabola that opens up or down.
( x - h )² = 4p( y - k )
Given the data in the question;
Focus: (0,7)directrix y = 1First, we determine the vertex.
The vertex ( h,k ) is half way between the directrix and the focus.
Find the y-coordinate of the vertex using;
y = ( y-coordinate of focus + directrix )/2
y = (7+1)/2 = 8/2 = 4
The x-coordinate of the vertex is the same as that of the focus 0
Hence, the vertex is ( 0,4 )
Next, we determine the distance p from the focus to the vertex.
p = y-coordinate of focus - y-coordinate of vertex
p = 7 - 4
p = 3
Now, plug the known values into the equation and simplify
( x - h )² = 4p( y - k )
( x - 0 )² = 4(3)( y - 4 )
x² = 12( y - 4 )
Therefore, the equation of the parabola with the given focus and directrix is x² = 12( y - 4 ).
