Answer:
[tex]15u^{2}[/tex]
Step-by-step explanation:
let's say each square is = [tex]1u^{2}[/tex]
triangle A area: 2*5
[tex]\frac{2*5}{2}=5u^{2}[/tex]
----------------------------------
triangle B area: 2*2
[tex]\frac{2*2}{2}=2u^{2} \\Triangle A - B = 5 - 2= 3u^{2}[/tex]
----------------------------------
next figure
triangle C area 3*3
[tex]\frac{3/3}{2}=4.5u^{2}\\ -------------\\\\3u^{2}+4.5u^{2}=7.5u^{2}\\ -------------\\[/tex]
And since the other figure is a reflection *2
[tex]7.5u^{2}*2=15u^{2}[/tex]
Answer:
A = 15 units²
Step-by-step explanation:
the area (A) of the shaded triangle is calculated as
A = area of rectangle enclosing the triangle - area of white triangles on either side of shaded triangle and the one on top
area of rectangle = 10 × 5 = 50 units²
area of 2 congruent triangles = 2 × [tex]\frac{1}{2}[/tex] × 5 × 5 = 5 × 5 = 25 units²
area of top triangle = [tex]\frac{1}{2}[/tex] × 10 × 2 = 5× 2 = 10 units²
A = 50 - 25 - 10= 15 units²

Jamie is planning on dropping a ball down from a tall building to measure its velocity. In the process, she also wants to know how tall the building is. She uses a weird measuring tool that finds that the ball traveled -700 feet. She doesn’t know how to translate this into an answer she and her teacher will understand. What can she do?
Answers
She can translate the measurement into metric unit system of "meters" for her and her teacher to understand better.
As per the question statement, Jamie dropped a ball down from a tall building to measure its velocity and the height of the building, and she used a weird measuring tool that gave a measurement the ball traveled "-700" feet.
We are required to provide a solution on how Jamie can translate this measurement so that, she and her teacher can understand it better.
To solve this question, we will simply ignore the "negative" sign that came along with the measurement, and convert the magnitude of the measured value into the metric unit system of meters, using the standard conversion rate of [1 foot = 0.305 meters], i.e.,
700 feet = (700 * 0.305) meters,
or, 700 feet = 213.5 meters.
Hence, the ball travelled 213.5 meters when dropped from the top of building, or, the height of the building is 213.5 m.
Metric Unit System: It is the decimal measuring system, based on the meter, liter, and grams as units of length, capacity, and weight or mass, which was first proposed by the French astronomer and mathematician Gabriel Mouton (1618–94) in 1670 and standardized in Republican France in the 1790s.To learn more about the Metric Unit System, click on the link below.

If the right triangle BAR were rotated 90° clockwise about Point B to what location would point A be relocated
Answers
Using rotation rules, considering the 90º clockwise rotation, the coordinates of point A are given as follows:
(-2,0).
What is the rule for a 90º clockwise rotation at a point other than the origin?The origin has coordinates (0,0), hence the rule for a 90º clockwise rotation about the origin is:
(x,y) -> (y, -x).
Considering a point (xP, yP) as reference, the rule for the coordinates of the vertices after the rotation is given as follows:
(x,y) -> (y - yP, -x + xP).
For this problem, point B is the reference point, hence the reference coordinates are as follows:
xP = 2, yP = 1.
Then the rule is:
(x, y) -> (y - 1, -x + 2).
Point A is located at:
x = -2, y = -1.
After the rotation, the coordinates will be given as follows:
(x, y) -> (-1 - 1, -2 + 2) = (-2,0).

A baker uses 1 1\2cups of flour to make 12 cupcakes. How much flour does the baker use to make 288 cupcakes?
Answers
We can find the answer using cross multiplication
First change 1 1/2 cups to 1.5 for easy math
1.5c flour / 12 cupcakes = x flour/ 288 cupcakes
1.5 x 288 = 12 x
432 = 12x
36 = x
36 cups flour for 288 cupcakes
You can also find the ratio of flour to cupcakes. 1.5 ➗ 12 cupcakes = .125
Multiply ratio of .125 x 288 cupcakes you get 36 cups flour.

One gram of protein contains 4 calories. One gram of fiber contains 2 calories. A protein bar has 80 calories from p grams of protein and f grams of fiber.
The equation 4p+2f=80 represents the relationship between these quantities.
Which pair of values could be the number of grams of protein and fiber in the protein bar?
Answers
Pairs of values that could be the number of grams of protein and fiber in the protein bar are:
10 grams of protein and 20 grams of fiber. That is, (10, 20)
and
15 grams of protein and 10 grams of fiber. That is, (15, 10)
Calculating value pairsFrom the question, we are to determine the pair of values that could be the number of grams of protein and fiber in the protein bar
From the given information,
The protein has 80 calories from p grams of protein and f grams of fiber
and
The equation that represents the relationship is
4p + 2f = 80
To determine the pair of values, we can determine the values of f for certain values of p
When p = 10
4p + 2f = 80
4(10) + 2f = 80
40 + 2f = 80
2f = 80 - 40
2f = 40
f = 40/2
f = 20
A pair of values is 10 grams of protein and 20 grams of fiber.
When p = 15
4p + 2f = 80
4(15) + 2f = 80
60 + 2f = 80
2f = 80 - 60
2f = 20
f = 20/2
f = 10
Thus,
Another pair of values is 15 grams of protein and 10 grams of fiber.

A statement which best describes the meaning of function f(150) is that: A. This is the average number of days the house stayed on the market before being sold for $150,000.
What is the average rate of change?The average rate of change can be defined as a type of function that is used for describing the average rate at which a quantity either decreases or increases with respect to another quantity.
What is a function?A function simply refers to a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable (x-value) to an output variable (y-value or f(x)).
In this scenario, the function f(150) can be evaluated as follows:
Function f(150) = 150 × p
Function f(150) = 150 × $1,000.
Function f(150) = $150,000
Therefore, the function f(150) simply means the average number of days this house stayed on the market before it was then sold for $150,000.

In coordinate geometry, a two-dimensional or three-dimensional space can be used to calculate the distance between two points using the distance formula. The Pythagoras theorem is sometimes used to calculate the distance between two places.
The distance between two locations on a plane is the length of the line segment connecting them. The following equation is frequently used to determine the separation between two points:

Given, the two points are A≡(7,10) and (9,-3)
On comparing A and B with (x₁, y₁) and (x₂, y₂) respectively, we get
x₁ = 7, y₁ = 10, x₂ = 9, y₂ = -3
