To reach his goal, Marcus will have to save $(600/m) each month.
What is a mathematical equation and expression?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Marcus has $400 in his savings account. He decides that he will put a fixed amount of money into his account every month. His goal is to save $1,000.
The formula describing the Marcus saving's scheme is -
1000 = 400 + xm.
where -
[x] - amount saved per month
[m] - number of months
Solving the equation further to find the amount saved per month is -
1000 = 400 + xm
1000 - 400 = xm
600 = xm
x = (600/m)
Therefore, Marcus will have to save $(600/m) each month to reach his goal.

330 ft
Answer:
Mr. Conners will use 144 fence posts.
Step-by-step explanation:
Given question is incomplete; please find the question attached herewith.
As we can see from the attachment, Mr Corner's yard is in the rectangular shape.
Total distance around the yard = Perimeter of a rectangle = 2(Length + width)
Length of the yard = 330 ft
And width of the yard = 102 ft
So perimeter of the yard = 2(330 + 102 = 864 f
Mr. Conners wants to put a fence post at every 6 feet.

You are ordering shirts for the math club at your school. Short-sleeved shirts cost $8 each. Long-sleeved shirts cost $16 each. You have a budget of $300 for the shirts. The equation $8x+16y=160$ models the total cost, where $x$ is the number of short-sleeved shirts and $y$ is the number of long-sleeved shirts. a. Graph the equation. Interpret the intercepts
On the graph, the graph equation has been drawn, crossing the y and x-axis points (0, 10) and (20, 0).
What is a graph equation?To calculate the slope m and the y-intercept, write the equation y = MX + b.
The slope and y-intercept can then be used to graph the equation (0, b).
The three primary forms of linear equations are point-slope, standard, and slope-intercept.
So, the equation is as follows:
8x+16y=160
Now,
The short sleeves are symbolized by an x.
y is a symbol for the long sleeves.
The equation must now be plotted as follows:
(Please see the graph below.)
As a result, the y and x-axis points (0, 10) and (20, 0) intersected by the equation.
Therefore, on the graph, the graph equation has been drawn, crossing the y and x-axis points (0, 10) and (20, 0).

The functions of an angle in a triangle are known as trigonometric functions, commonly referred to as circular functions. In other words, these trig functions provide the relationship between a triangle's angles and sides.
There are five fundamental trigonometric functions: sine, cosine, tangent, cotangent, secant, and cosecant.
Function of Sine
The ratio of the opposing side's length to the hypotenuse is known as an angle's sine function. According to the diagram above, sin is worth:

The height of the flagpole in this problem is calculated as follows:
12.9 feet.
How to obtain the height of the flagpole?The height of the flagpole in this problem is obtained using similar triangles, as shown by the image given at the end of the answer.
Similar triangles are used because the equivalent sides have proportional side lengths.
From the image given at the end of the answer, the equivalent sides of each triangle are given as follows:
8 ft and 20 ft.5 and 2/12 ft and x ft. (2/12 is because one feet = 12 inches, x feet is the height of the pole).Then the proportional equation is given as follows:
8/20 = 5.1667/x
Applying cross multiplication, the height of the flagpole is calculated as follows:
8x = 20 x 5.1667
x = 20 x 5.1667/8

Minimize subject to: z = 5x + 3y
8x + 5y = 40
4x+10y = 40
x ≥ 0
y ≥ 0.
There are no local extrema since there isn't any x value that causes the first derivative to be equal to 0.
How to find the calculation?z = 5x + 3 y
Discover the function's first derivative.
By applying the Sum Rule, the derivative of 5 x + 3 y with respect to x is d d x [ 5 x ] + d /d x [ 3 y ].
d/d x [ 5 x] + d /d x [ 3 y]
Analyze d /d x [ 5 x ].
Tap to take other actions...
5 + d /d x [ 3 y]
Because 5 is independent of x, its derivative is 5 d d x [ x ] since 5 is constant with respect to x.
5 d/ d x [ x ] + d /d x [ 3 y]
The Power Rule, which asserts that d d x [ x n ] is n x n 1 where n = 1. 5 1 + d d x [ 3 y ] is a method of differentiation, says that you should differentiate.
Subtract 1 from 5 and multiply the result by 5 + d /d x [ 3 y ]
The Constant Rule can be used to differentiate.
Because 3 y is constant in relation to x, its derivative in relation to x is 0 (5 + 0).
Subtract 5 from 0 to get 5.
Since 5 is constant in relation to x, its derivative in relation to x is 0 (f " (x ) = 0).
By setting the derivative to 0, you can solve the problem and discover the function's local maximum and lowest values.

The combined area of the shaded triangles in figure one is 2ab. We have four congruent right triangles given, with legs a and b. The formula to calculate the area of a right triangle is (leg * leg) / 2. So the area of one of the triangles is ab/2. We have four of these triangles, so ab/2 * 4 = 2ab.
The area of the unshaded square in figure one can be represented as c^2. Since the side of the square is given as c, its area must be c^2 (calculate the area of a square by multiplying its side length by itself).
The combined area of the unshaded squares in figure 2 can be represented by a^2 + b^2. Again, we find the areas of each square by multiplying the side lengths togther: (a * a) + (b * b) = a^2 + b^2.
Finally the areas of the squares in figure one and figure two show that a^2 + b^2 = c^2. This is because the shaded triangles in figure one take up the same area as that of figure two. And since the total figure areas are the same, the unshaded parts of each figure must be equal to each other. Therefore, we have a^2 + b^2 = c^2. This is also known as the Pythagorean Theorem.
A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 45 pounds and each large box of paper weighs 75 pounds. There were 3 more small boxes shipped than large boxes and the total weight of all boxes was 1455 pounds. Write a system of equations that could be used to determine the number of small boxes shipped and the number of large boxes shipped. Define the variables that you use to write the system.
The system of equation is 45x+75y=1455.
The number of small boxes is 14 and large boxes is 11.
In the given question,
The paper will be shipped in small boxes and large boxes.
Each small box of paper weights 45 pounds.
Each large box of paper weights 75 pounds.
There were 3 more small boxes shipped than large boxes and the total weight of all boxes was 1455 pounds.
We have to write a system of equations that could be used to determine the number of small boxes shipped and the number of large boxes shipped.
We also have to define the variables that we use to write the system.
Let x be the number of small boxes.
Let y be the number of large boxes.
There were 3 more small boxes shipped than large boxes.
So x = y+3
Weight of x number of small boxes = 45x
Weight of y number of small boxes = 75y
Total weight of boxes = 1455
So; 45x+75y=1455
Now putting the value of x to this system of equation
45(y+3)+75y=1455
45y+135+75y=1455
120y+135=1455
Subtract 135 on both side, we get
120y=1320
Divide by 120 on both side, we get;
y=11
Now putting the value of y in x=y+3
x = 14
Hence, the number of small boxes is 14 and large boxes is 11.

Find m ∠ K.

Angle K has a value of 63 degrees.
Given,
The triangle KLM
Angle L = 4x + 7
Angle K = 6x - 9
Angle M = 118° (Exterior)
We have to find the value of angle K.
Here,
Angle M (Interior) = 180 - 118 = 62° (linear pair of angles)
Now,
Angle L + Angle K + Angle M = 180° (Sum of interior angles of a triangle)
Then,
4x + 7 + 6x - 9 + 62 = 180
10x - 2 + 62 = 180
10x + 60 = 180
10x = 180 - 60
x = 120/10
x = 12
Now,
Angle K = 6x - 9 = 6 × 12 - 9 = 72 - 9 = 63

Doug has $100,000 in a savings account that earns 13% interest per year. The interest is
not compounded. How much interest will he earn in 4 years?
PLEASE HELP AGAIN!!!!
Answer:
If Doug has $100,000 in a savings account that earns 13% interest per year and the interest is not compounded, then after four years he will earn $52,000 in interest. This is because 13% of $100,000 is $13,000, and since the interest is not compounded, this amount will remain constant for each year. Therefore, after four years Doug will earn a total of $13,000 + $13,000 + $13,000 + $13,000 = $52,000 in interest.
In general, if a savings account earns x% interest per year and the initial amount in the account is y dollars, then after n years the account will earn n * (x/100) * y dollars in interest. For example, if the interest rate is 13% and the initial amount is $100,000, then after four years the account will earn 4 * (13/100) * $100,000 = $52,000 in interest.
