Answer: 6 dollars
Step-by-step explanation:
Freida would have earned at the end of the year an interest of $6 for the $200 investment at 3% interest for 1 year.
The principle amount is $200
The saving account earns a interest of 3%
We need to calculate that Frieda have earned at the end of the year.
Interest = PRT/100
where p is principle
r is rate of interest
and t is the time period
= 200 x 3 x 1 / 100
= 6
Therefore, Freida would have earned an interest of $6 for the $200 investment at 3% interest for 1 year.

The siding of a house is 2250 square feet. The siding needs two coats of paint.
1 quart costs 18 dollars and covers 80 square feet;
1 gallon, costs 29 dollars, covers 320 square feet.
A. What is the minimum cost of the paint needed to complete the job?
B. How much paint is left over when you spend the minimum amount?
Answer: Minimum cost = $264
Paint left over = 7/8 qt
Step-by-step explanation:
6 gal covers 1920 sf (6 gal x 320 sf/gal)
6 gal x $29/gal = $174
2250 sf - 1920 sf = 330 sf
Need 4.125 qt to cover 330 sf, but you can't buy a partial quart
5 qt x $18/qt = $90
Total cost = $174 + $90 = $264
You have 7/8 qt left over
0.721x10 to the second power
Answer:
72.1
Step-by-step explanation:
It is 10 to the power of 2 because the exponent is 2. The result is a number bigger than the origin or base number because the exponent is positive. We move the decimal two times to the right to arrive at our conclusion:
0.721--> 72.1
therefore, your answer will be 72.1

Danny’s home cost $350,000. If the federal government program for flood damage insurance covers only $150,000, what percent of the total value does this represent?
Amount of $150,000 represents 42.86% of $350,000.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Danny’s home cost $350,000. The federal government program for flood damage insurance covers only $150,000.
Assume that it represents [x%] percent of the total value. Then, we can write -
x = (150000/350000) x 100
x = 42.86%
Therefore, $150,000 represents 42.86% of $350,000.

Suppose you sell 8,000 of the 3 pack of lenses described in question 3 above in one year. You cost on each 3 pack is $29.95 and you sell them for $59.95. If your operating expenses for the year total $144,080, what are your Net Income and Net Profit Margin Percentage?
Your net income and Net profit margin percentage, given the cost of the pack of lenses, and your operating expenses are:
Net income - $95, 920Net profit margin percentage - 19.3%How to find the net income?To find the net income, first find the revenue:
= Number of packs x selling price
= 8, 000 x 59.95
= $479,600
The cost of goods sold is:
= Cost of lenses x number of lenses
= 29.95 x 8,000
= $239, 600
The net income is:
= Revenue - cost of goods sold - operating expenses
= 479, 600 - 239,600 - 144,080
= $95, 920
The net profit margin percentage is:
= Net income / total revenue
= 95, 920 / 497, 600

Turn into vertex form x^2= 9x-20
The vertex form of the given equation is (x - 9/2)² - 1/4
Vertex form
The general vertex form is written as
y = a (x - h)² + k
Where, a, h, and k are real numbers, where a ≠ 0.
And x and y are variables where (x, y) represents a points.
Given,
Here we have the equation x² = 9x - 20
Now, we have to convert this equation into vertex form.
In order to convert this into vertex form, first we have to rewrite the given equation as follows:
=> x² - 9x + 20 = 0
Here the coefficient of the x is 9, so now we divide this by 2 :
=> 9 ÷ 2 = 9/2
And then we have to square it (9/2) ² then we get the value 81/4.
So we add and subtract 81/4, then we get,
=> x² - 9x + 81/4 - 81/4 + 20 = 0
Now, we have to rewrite it as,
=> [x² - 9x + 81/4] + [-81/4 - 20]
When we simplify it then we get,
=> (x - 9/2)² - 1/4
Therefore, the vertex form of the equation is (x - 9/2)² - 1/4.

The vertices of a triangle are p(-1,4) Q (8,-3) and R(2,-6) Name the vertices of R y-x (PQR)
The reflection of the points P(-1, 4), Q(8, -3) and R(2, -6) across the line y = x are P'(1, -4), Q'(-8, 3) and R'(-2, 6).
First, let us understand the reflection of a point:
The reflection of a point or set of points across the line y = x results in a point or set of points whose coordinates are the interchange of the x-value and the y-value of the original point or set of points.
We are given:
The vertices of a triangle are P(-1, 4), Q(8, -3) and R(2, -6).
We need to find the reflection of the points across the line y = x.
So,
P(-1, 4) = P'(1, -4)
Q(8, -3) = Q'(-8, 3)
R(2, -6) = R'(-2, 6)
Thus, the reflection of the points P(-1, 4), Q(8, -3) and R(2, -6) across the line y = x are P'(1, -4), Q'(-8, 3) and R'(-2, 6).

What are Zeroes of the polynomial?The locations where a polynomial becomes zero overall are known as the zeros of the polynomial. The term "zero polynomial" refers to a polynomial with a value of zero . The highest power of the variable x is referred to as a polynomial's degree. A linear polynomial is a polynomial with degree 1.
Given:
f(x)=5x³+7x²−81x+45.
let us take x= 3
5(27)+7(9)-81(3)+45
=135+63-243+45

Now, divide 5x³+7x²−81x+45 by x-3 we get 5x²+22x-15
Now, factorise 5x²+22x-15.
= 5x²+25x-3x-15

When corresponding angles are congruent, the lines are parallel
Congruent AnglesCongruent angles are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other. The type of angles does not make any difference in the congruence of angles, which means they can be acute, obtuse, exterior, or interior angles. The angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
Examples of the corresponding angle are any angles which are formed on the opposite side of the transversal. Now, it should be noted that the transversal can intersect either two parallel line or two non-parallel lines. Thus, corresponding angles can be of two types:
Corresponding angles formed by parallel lines and transversals
Corresponding angles formed by non-parallel lines and transversals
Looking at the image, angle I is congruent to each other. Angle II is congruent with each other as well as angle III.

Step-by-step explanation:

Line a has to be perpendicular to Line b.
Perpendicular transversal theorem:
In a plane, if a line is perpendicular to one of two parallel lines , then it is perpendicular to the other line also.
In this case, a||c, and line b is perpendicular to line c.
We can therefore use perpendicular transversal theorem to state that line a is perpendicular to line b.
