Answer:
9350 m²
Step-by-step explanation:
There are several ways you can go at this. Here are 3 of them:
along an extension of the lower right vertical edge, divide the figure into a rectangle and a right triangle.between the upper left corner and the inside corner at lower right draw a diagonal line to divide the figure into a trapezoid and a triangle.subtract the area of the trapezoid at the right from the area of the bounding rectangle__
The relevant formulas for area are ...
rectangle: A = LW . . . . . . . . . . . length times width
trapezoid: A = (1/2)(b1 +b2)h . . . b1, b2 are the bases, h is the height
triangle: A = (1/2)bh . . . . . . . . . . . b is the base, h is the height
__
Here's what those computations look like:
1. rectangle: 60m wide by 80 m high = 4800 m².
right triangle: base 190-60 = 130 m; height = 80-10 = 70 m.
area = (1/2)(130 m)(70 m) = 4550 m²
figure area = 4800 m² +4550 m² = 9350 m² . . . . area of figure
__
2. The trapezoid has bases of 80 m and 10 m, and a height of 60 m. Its area is ...
A = (1/2)(80 m +10 m)(60 m) = 2700 m²
The triangle has a base of 190 m and a height of 80-10 = 70 m. Its area is ...
A = (1/2)(190 m)(70 m) = 6650 m²
Then the total area is 2700 m² +6650 m² = 9350 m² . . . total area
__
3. The bounding rectangle is 190 m by 80 m, so its area is ...
A = LW = (190 m)(80 m) = 15200 m²
The (negative) trapezoid at right has bases of 10 m and 80 m, and a width of 190-60 = 130 m. Its area is ...
A = (1/2)(10 m +80 m)(130 m) = 5850 m²
The area of the figure is the difference between these:
figure area = 15200 m² -5850 m² = 9350 m² . . . figure area

Feng needs to build a rectangular shipping box with a volume of 9 cubic feet. He has two pieces of plywood that measure 2 feet wide and 3 feet long to serve as the bases of the box. How tall must Feng make the box?
Answers
Answer:
54 feet
Step-by-step explanation:
9x3x2=54
Answer:
1.5 feet
Step-by-step explanation:
The box needs to have a volume of 9 cubic feet.
Volume is l*w*h.
We know the width is 2 ft and the length is 3 ft.
2*3*h=9
6*h=9
Divide by 6
h=9/6
h=1.5

Matthew had to make a bridge for his math class. It had to be at least 1 1/2 feet long. Harold made a bridge that was 2/13 times as long as Matthew’s. Write and solve an equation that will help you figure out how long Harold’s bridge was. Explain the steps you took to solve the problem.
Answers
Answer:
Step-by-step explanation:
2 / 13 = 15.38% or 15.38..... If Matthew's bridge is 1 1/2 feet long which is 45.72cm then 45.72 + 15.38 = 61.1cm > convert into feet > 1.55194 ft.

Brayden is working two summer jobs, making $21 per hour tutoring and making $10 per hour landscaping. In a given week, he can work a maximum of 12 total hours and must earn no less than $170. If xx represents the number of hours tutoring and yy represents the number of hours landscaping, write and solve a system of inequalities graphically and determine one possible solution.
Answers
Answer:
2 hours.
Step-by-step explanation:
Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9
= $297 but he wants to work a minimum of hours for a minimum of 270.
Thus we have the inequality:
252 + 9x ≤ 270
9x ≤ 18
x ≤ 2.
So the number of hours he must do clearing tables = 2.
Answer:
The set of two or more inequalities in one or more variables is referred to as a system of inequalities, and the further discussion can be defined as follows:
System of inequalities:Get y alone on one side of a linear inequality with 2 variables (x,y). Consider the equation that results when the inequality sign is changed to an equality sign. This equation has a line as its graph. A dashed line is drawn if the inequality is strict.From the question, we know
[tex]21 x+10y \geq 170[/tex] money
[tex]x+y \leq 12[/tex] hours
so
Inequality [tex]1 : y\geq - \frac{21}{10} x+17\\\\[/tex]
Inequality [tex]2 : y\leq -x+12\\\\[/tex]
and [tex]x=0, y= 0[/tex]
For example
[tex]y = 2 \ \ \ x=10[/tex]

The width of a rectangular room is 80% of its length. If the length of the room is 20 meters, what is the area of the room? A= length x width
Answers
Answer:320ft^2
Step-by-step explanation:
80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area
Length x width = area
