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

Gracie went out to eat. She ordered chicken tenders for $11.50 and a soft drink for $1.25. She wants to leave a 20% tip. How much total money will Gracie spend on her meal plus tip?
Answers
Gracie will spend $15.30 on her meal in total.
Step-by-step explanation:
First, you need to start by adding the cost of the chicken tenders and the soft drink together. Once this is done, you get the total cost of the meal without tax which is $12.75.
To find the tax, multiply $12.75 by 0.2, which gets you the price of the tax, $2.55.
You then add the cost of the meal without tax and the tax together, which would look something like this: $12.75+$2.55
Adding these two together would get you the total price of the meal with tax, which is $15.30
Answer:
[tex]\boxed{\textsf{ The net amount to be paid is \textbf{ \$ 15.30 }}}[/tex]
Step-by-step explanation:
Given that Graice went out to eat and she ordered chicken tenders for $ 11.50 and a soft drink for $ 1.25 . She also wants to leave a tip of 20% of the total amount . So ,
=> Total amount that should be paid = Amount of chicken tenders + Amount of soft drink.
= $( 11.50 + 1.25 )
= $ 12.75
Now on this amount she wants to give a tip of 20 % . So the net amount wil be ,
[tex]\sf\implies Net_{(Amount)}= Total \ cost + 20\% \ of \ Total \ cost \\\\\sf\implies Net_{(Amount)}= \$ 12.75 + 20\% of \$ 12.75 \\\\\sf\implies Net_{(Amount)}= \$ (12.75 + 2.55 )\\\\\sf\implies \boxed{\pink{\sf Net_{(Amount)}= \$ 15.30 }}[/tex]

Answers
Answer:
Sales tax = $2.79
Step-by-step explanation:
(18 x 48.6) /100
= 8.748 = $8.75 tip amount total
48.60-8.748 = 39.852 sales total
(39.852 x 7)/100
= 2.78964 = $2.79 sales tax
39.852 - 2.78964 = 37.06236 = $37.06 cost of bill
Sales tax was asked = $2.79

A circular fountain has a radius of 9.4 feet. Find its diameter and circumference to the nearest hundredth. ( Please help)
Answers
Answer:
The diameter is 11.20 feet. The circumference is approximately 35.17 feet.Step-by-step explanation:
Use the formula.
d = 2r The diameter of a circle is the same as 2 times the radius.
d = 2(5.6) The radius is 5.6. Substitute 5.6 for r.
d = 11.20 Multiply.
Use the formula.
C = πd
C = π(11.20) The diameter is 11.20. Substitute 11.20 for d.
C ≈ 3.14(11.20) Substitute 3.14 for π.
C ≈ 35.17 Multiply.
The diameter is 11.20 feet.
The circumference is approximately 35.17 feet.

Find the equation of a line that is perpendicular to the line y=1/9x+4 and contains the point (-9,0).
Answers
Answer:
When you are finding a line that is perpendicular, you need to look at the slope. In the format, y=mx+b, the m represents the slope. In this case, the slope (m) of the line is -1/9. A line with a perpendicular slope is the negative inverse. The negative inverse for -1/9 is 9/1. Once you know the slope, you can begin to plug in the new information in order to find the new b (y intercept).
New Line information:
m=9/1, (2,-5) --> this means that x = 2 and y = -5
y=mx+b
-5 = 9/1(2) + b
-5 = 18 + b
-23 = b
Once you find the b, you plug the b and m into the equation y = mx + b
y = 9/1x -23
