For the years 1970 through the projection of 2014, the number of men receiving degrees (in thousands) is given by the equation y= 3.6x + 444 and for women, the equation is y= 14.2x + 315 where x is the number of years after 1970.
The solution to the system of equations is x = 12
Equal number of men and women have received bachelor's degrees up till 1982Women have a higher rate of receiving bachelor's degrees each year than menThe solution to the system of equationsThe system of equations is given as
y = 3.6x + 444
y = 14.2x + 315
Substitute y = 14.2x + 315 in y = 3.6x + 444
14.2x + 315 = 3.6x + 444
Evaluate the like terms
10.6x = 129
Divide both sides by 10.6
x = 12
Interpret the result in (a)In (a), we have
x = 12
Where
x is the number of years after 1970.
This means that
Year = 1970 + 12
Evaluate
Year = 1982
So, it means that the total number of men and women that have received bachelor's degrees up till 1982 are equal

The result of the expression (x / m^2 - 2x / m)(3x^2y / m) is (3x^3y / m^3) - (6x^3y / m^2)
The given expression is
(x / m^2 - 2x / m)(3x^2y / m)
Here we have to apply distributive property
The distributive property states that multiplying the sum of two or more variable by a number gives the same result as when each variable is multiplied individually by the number and the products are added together.
The distributive property of subtraction is
A(B-C) = AB - AC
Apply the distributive property
(x / m^2 - 2x / m)(3x^2y / m)
= (x / m^2)(3x^2y / m) - (2x / m)(3x^2y / m)
Multiply the terms
= (3x^3y / m^3) - (6x^3y / m^2)
Hence, the result of the expression (x / m^2 - 2x / m)(3x^2y / m) is (3x^3y / m^3) - (6x^3y / m^2)

when it was first born. 20 days
later, it weighed 10.8 lbs. what is the rate of change of the baby's weight per day?
0.115 lbs/day is the rate of change of baby's weight.
What is rate of change ?When anything changes over time, it does so at a certain rate, or ROC. Therefore, rather than the size of each change individually, it is the pace of change—or, more specifically, its acceleration or deceleration. Rate of change in the financial world is utilized to comprehend price returns and spot trend momentum.

The percentage of time he exceeds 13,000 steps is 2.28% or 0.0228.
Percentage
Use the percentage formula to express a number or percentage in terms of 100. % simply indicates one out of one hundred. An expression for a number between 0 and 1 can be made using the percentage formula. It is a number that is represented as a fraction of 100. The sign % is used to denote it and it is mostly used to compare and calculate ratios. The formula for percentage increases is the ratio of the increased value to the original value multiplied by 100. It is described in percentage form. If anything is valued more highly, both its value and proportion will rise.

iceberg is 15 meters below sea level.
What is the total height and depth of
the iceberg.
The total height of the iceberg is 38 meters and the total depth of the iceberg is 15 meters.
What is meant by height and depth?Height is a mathematical term that refers to the vertical distance between an object's top and base. Sometimes, it has the designation altitude. The measurement of an item along the y-axis in coordinate geometry is referred to as height in geometry.
The depth of an object is the separation between its closest and farthest ends. Jane, for instance, measures a box. Jane estimates the depth of the box by calculating the distance between the end of the box that is closest to her and the end that is farthest away.
Given, the height of an iceberg above the water is 23 meters.
And also given that the bottom of the iceberg is 15 meters below sea level.
Total height = above the water + below the water
Total height=23+15=38 meters
Depth= total height - iceberg above the water
Depth=38-23=15 meters
The total height of the iceberg is 38 meters.

Agnes pays state income tax equal to 3.75% of her federal taxable income. She pays federal income tax equal to 28.4% of her federal taxable income. This year she paid $15,449.60 in federal income tax. How much did Agnes pay in state income tax?
The amount that Agnes paid in state income tax is; SI = $2,040
How to calculate state income tax?To find the state income tax in this situation, we would use this equation:
t = px
Where;
t = Total paid
p = percentage
x = federal income tax
In this case, we would need to find what x is.
We are given;
Total paid = $15,449.60
Percentage of federal tax = 28.4% = 0.284
The equation is;
15,449.60 = 0.284x
dividing both sides by 0.284 gives;
x = $54,400.
Now, we can calculate Agnes' state income tax from the formula:
SI = x × p
SI = 54400 × 0.0375

How to find the equation of a line?The equation of a line can be represented in different form such as point slope form, slope intercept form, standard form and general form.
The equation of a line in slope intercept form is as follow:
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line passes through (-5,0) and is parallel to the line y = -2/3x - 1.
Parallel line has the same slope.
Therefore, the slope of the line is - 2 / 3.
Hence, let's find the y-intercept using (-5, 0)
0 = - 2 / 3(-5) + b

What is Parallelogram? What is triangle?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a parallelogram in which EFGH the measure of angle E is (2x+3) and the measure of angle F is (3x - 33).
We can write -
2(2x + 3) + 2(3x - 33) = 360°
4x + 6 + 6x - 66 = 360°
10x - 60 = 360
10x = 420
x = 42
∠E = 2 x 42 + 3 = 84 + 3 = 87°
∠F = 3 x 42 - 33 = 126 - 33 = 93°
Therefore, the measure of ∠E = 87° and ∠F = 93°.
