Using the given function, it is found that:
6 students need to be enrolled for the instructor to make a profit.20 students must be enrolled for the instructor to make a profit of $1,000 a month.What is the profit function?The profit when n students are enrolled in the class is given by:
f(n) = 70n - 400.
A profit is made when f(n) > 0, hence:
70n - 400 > 0
70n > 400
n > 5.71.
6 students need to be enrolled for the instructor to make a profit.
A profit of $1,000 is made when f(n) = 1000, hence:
70n - 400 = 1000
70n = 1400.
n = 20.
20 students must be enrolled for the instructor to make a profit of $1,000 a month.

a^4 + a^2 + 1
a^4 + a^2 + x + 1
a^2 ( a^2 + 1) + 1 ( x + 1)
so, here clearly we can see that If wee add a^2 in place of x it would be a perfect square..

A baker needs a total of 13 and one-third cups of flour to make four batches of cookies. how much flour, in cups, does she need for each batch of cookies? write and solve an equation to find the answer. startfraction 5 over 6 endfraction 3 and one-third 9 and one-third 12
Answer:
(b) 3 1/3 cups
Step-by-step explanation:
The amount of flour per batch is found by dividing the given amount of flour by the given number of batches.
__
(13 1/3 cups)/(4 batches) = (40/3 cups)/(4 batches) = (40/3)(1/4) cups/batch
= 10/3 cups/batch = 3 1/3 cups per batch
For triangle xyz , the measures of angles x,y, and Z are known. Which method should be used to start solving triangle xyz?
law of sines
law of cosines
neither law can be used
both laws can be used
The triangle xyz has three sides and three angles
Neither law can be used to solve the triangle
How to determine the appropriate method?As a general rule, the law of sines states that:
x/sin(X) = y/sin(Y) = z/sin(Z)
As a general rule, the law of cosines states that:
x^2 = y^2 + z^2 - 2yz cos(X)
From the question, we understand that only the angle measures are given.
The sine and the cosine laws above require at least one side length of the triangle in order to solve the triangle
Since the side lengths are not known, then neither of the laws can be used

Answer:

rhombus
Step-by-step explanation:
In geometry, arrows on lines mean that those lines are parallel.
Therefore, as one pair of opposite sides have 1 arrow, and the other pair of opposite sides have 2 arrows, this indicates that each pair of opposite sides are parallel.
Quadrilaterals that have 2 pairs of parallel sides are the rhombus and the parallelogram. A rhombus is a parallelogram that has 4 sides of equal length. As the side lengths of the given shape are equal in length, this quadrilateral is a special type of parallelogram called a rhombus.

Solve for x.
7.5x11=4.85
Answer:
x = .005
Step-by-step explanation:
7.5x (11) = 4.85
7.5x = 4.85/11
7.5x = 0.441
x = 0.441/7.5
x = .005 ans
The perimeter of the shaded face of this cube is 12 centimeters. What is the volume of the cube in cubic centimeters?
Answer:
1728
Step-by-step explanation: L(length) H(height) W(width)
volume = l x w x h
perimeter= L + W + L + W
perimeter = 12 + 12 + 12 + 12
volume = 12 x 12 x 12 because it' s a cube, and all sides are equal
= 1728

Answer:
can you make the pirure a little better
Step-by-step explanation:
At the end of a baseball game, the players were given the choice of having a bottle of water or a box of juice. Of all of the players, 12 chose a bottle of water, which was 3 4 of the total number of players. Write and solve an equation to determine p. the total number of players at the baseball game. Show your work
Answer:
p=48
Explenation:
Total number of players = p
According to given scenario:
p - 12 = 3/4p
By simplifying
Taking terms with p on left and constants on right
p - 3/4p = 12
By taking LCM for left side to make denominators same
4/4*p -3/4p = 12
(4p -3p)/4 = 12
1p/4 = 12
Multiplying both sides by 4 we get
p = 12 * 4
p = 48
So total number of players is 48

what is the inequality shown
Answer:
-4 ≤ x ≤ 3
Step-by-step explanation:
Well, we can see that the endpoints land on -4 and 3 and the numbers between -4 and 3 are included. And since the endpoints -4 and 3 have colored dots, they are included as well. Therefore the inequality is -4 ≤ x ≤ 3.
Answer:
-4 ≤ x ≤ 3
Step-by-step explanation:
Because the circles are closed, we know that the inequaily sign will be either "≤" or "≥", meaning that the dotted points are included. Looking at the number line, we can see that the dots lie on points -4 and 3. Because -4 is less than 3, the sign will be a lesser than sign. The line inbetween includes all numbers between -4 and 3.
So, in conclusion, -4 ≤ x ≤ 3 is the inequality shown.

Answer:
$64,082.25
Step-by-step explanation:
$205,375-16,050=189,325
189,325×33% (or .30)=62,477.25
16,050×10% (or .10)=1,605
1,605+62,477.25=$64,082.25

Suppose m and n vary inversely and n=17 when m=-4. A) write an equation that models the variation . B) find n when m =-136
The equation that models the variation is -4 = k/17.
The value of n when m is -136 is 2.
What is inverse proportion?When two variables vary inversely, as one variable increases, the other variable decreases.
The formula used to represent inverse proportion is:
m = k/n
m = dependent variable n = independent variable k = constant of proportionality-4 = k/17
k = 17 x -4 = -68
-136 = -68/ n
n = -136 /68
n = 2
