Figures 1 and 2 below show two polygonal regions used to approximate the area of the given shape. Find the average area, in square units, of the given shape using figures 1 and 2.
Answers
Answer:
figure 1 is 8.5 units^2 and figure 2 is 3 units^2 and the average are is 5.25 units^2
The overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Since the area is covered with either a square or a triangle. Therefore, we can write the area of this two as,
Area of a square = 1 unit × 1 unit = 1 unit²
Area of triangle = 0.5 × 1 unit × 1 unit = 0.5 units²
The overestimated area, the number of square and triangles are,
Number of square = 6
Number of triangle = 5
Total overestimated area = (6×1unit²) + (5×0.5unit²) = 8.5 unit²
The under estimated area, the number of square and triangles are,
Number of square = 2
Number of triangle = 2
Total Underestimated area = (2×1unit²) + (2×0.5unit²) = 3 unit²
Furthermore, the average area is,
Average area = (Total overestimated area - Total Underestimated area)/2
= (8.5 units² - 3 units²) / 2
= 5.5 units² / 2
= 2.75 units²
Hence, the overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.

A bakery used 37% more chocolate chips this month than last month. If the bakery used 320 pounds of chocolate chips last month, how much did it use this month?
Answers
Explanation: 320 x 37% = 320 x 0.37 = 118.4 so 320 + 118.4 = 438.4
Answer:
438.4
Step-by-step explanation:
100% + 37% = 137% = 1.37
320 x 1.37 = 438.4

Mr. Ford Invested $12,450 in a bank at 7.25% per annum simple interest for 6 years. calculate the interest he was paid
Answers
Answer:
If my calculations are correct, $5415.75 of interest was paid throughout 6 years.
Step-by-step explanation:
7.25% of 12,450 is 902.625.
If the interest being paid was the 7.25% of 12,450 throughout the 6 years then the answer is 902.625 x 6 ( the amount of years ) = $5415.75.
In other cases such as 7.25% of the new number of invested money after the loss of 902.625 then this answer is wrong, but I solved as I understood.
Hope this helps.

WXYZ has vertices W(6,2), X(3,7), Y(-1,4), and Z(4,-2)
a)Find perimeter
b)Find the perimeter of the image of WXYZ after dilation of 1/2 centered at origin and compare it to perimeter of WXYZ

Answer:
23,11333753
Step-by-step explanation:
1. Use The Coordinates To Find The Distances Of The Four Sides
2. The Formula For Perimeter Or A Quad =
AB + BC + CD + AD
Basically Add The Distances Of The Four Sides
So: WX + XY + YZ + WZ
[tex] \sqrt{34} + 5 + \sqrt{61} + 2 \sqrt{5} [/tex]
= 23,11333753
.°. 23,1

We can write the parameter as -
P = 23.13P = 11.55What is a quadrilateral?In geometry a quadrilateral is a four-sided polygon, having four edges and four corners.
Given is that WXYZ has vertices W(6, 2), X(3, 7), Y(-1, 4), and Z(4, -2).
The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 - dimensional plane, the distance between points (x₁, y₁) and (x₂, y₂) is given by the Pythagorean theorem -{d} = √{(x₂ - x₁)² + (y₂ - y₁)²}
{ a } -
WX = 5.83
XY = 5
YZ = 7.8
ZW = 4.5
So the perimeter would be -
P = WX + XY + YZ + ZW
P = 5.83 + 5 + 7.8 + 4.5
P = 23.13
{b} - After the dilation, the sides will become -
WX' = 5.83/2 = 2.9
XY' = 5/2 = 2.5
YZ' = 7.8/2 = 3.9
ZW' = 4.5/2 = 2.25
The perimeter will be -
P = WX' + XY' + YZ' + ZW'
P = 2.9 + 2.5 + 3.9 + 2.25
P = 11.55
Therefore, we can write the parameter as -
P = 23.13P = 11.55To solve more questions on dilations, visit the link below -

Write the equation of a circle with center (0,−6) and radius 4 in general form.
Answers
Answer:
x^2 + (y + 6)^2 = 4^2
Step-by-step explanation:
The general form we need here is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.
If the center is at (0, -6) and the radius is 4, then the desired equation is
(x - 0)^2 + (y + 6)^2 = 4^2, or just
x^2 + (y + 6)^2 = 4^2

Which expression models the phrase "Wally mowed two more lawns than he mowed last week"? n + 2 n minus 2 2 minus n 2 n
Answers
Given:
The phrase is "Wally mowed two more lawns than he mowed last week".
To find:
The expression that models the given phrase.
Solution:
Let the number of lawns mowed by Wally last week be n.
We know that, we use plus sign "+" for "more".
If Wally mowed two more lawns than he mowed last week, then the lawns mowed by the Wally this week is the sum of n and 2.
Lawns mowed this week = [tex]n+2[/tex]
The required expression for the phrase "Wally mowed two more lawns than he mowed last week" is n+2.
Therefore, the correct option is A.

Write an equation of a parabola opens upwards and has vertex (7, - 6).
Any help?
Answers
Answer:
f(x) = x² - 14x + 43
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (7, - 6 ) , then
f(x) = a(x - 7)² - 6
Since the parabola opens upwards then a > 0
let a = 1
f(x) = (x - 7)² - 6 ←in vertex form
f(x) = x² - 14x + 49 - 6
f(x) = x² - 14x + 43 ← in standard form

Answers
Answer:
[tex]Area = 455.11\ in^2[/tex]
Step-by-step explanation:
Given
[tex]Patches = 8\ by\ 8[/tex]
[tex]Length = 2\frac{2}{3}\ in[/tex] each
Required
The area of the quilt
First, calculate the length of the quilt.
[tex]Length = 8 * 2\frac{2}{3}[/tex]
[tex]Length = 8 * \frac{8}{3}[/tex]
[tex]Length = \frac{64}{3}[/tex]
Next, the width
[tex]Width= 8 * 2\frac{2}{3}[/tex]
[tex]Width= 8 * \frac{8}{3}[/tex]
[tex]Width = \frac{64}{3}[/tex]
The area is then calculated using:
[tex]Area = \frac{64}{3} * \frac{64}{3}[/tex] i.e. Length * Width
[tex]Area = \frac{4096}{9}in^2[/tex]
[tex]Area = 455.11\ in^2[/tex] --- approximated

The linear equation that represents the total amount paid is 1000 + 250x.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given,
Amount of down payment = $1000
Per month payment = $250
For x number of months = $250x

Answers
Answer:

∠ZA = (2x + 10)° and m
∠ZB = (3x + 15)
Find:
Measure of ∠ZB
Computation:
complementary angles
a + b = 90°
∠ZA + ∠ZB = 90°
(2x + 10) + (3x + 15) = 90
5x + 25 = 90
x = 13
So,
∠ZB = (3x + 15)
∠ZB = 13(3) + 15
∠ZB = 54°
