Answer:
4.35
Step-by-step explanation:
(1 * 0.35) + (2 * 0.2) + (5 * 0.1) + (8 * 0.2) + (10 * 0.15) = 4.35
Kite:
10.2 x 8 = 81.6/2 = 40.8 ft^2
pentagon:
area = 1/2 x apothem x perimeter
perimeter = length of side x number of sides
pentagon has 5 sides, perimeter = 5 *20 = 100
area = 1/2 x 14 x 100 = 700 in^2
Answer: (x+ 13, y+13)
Step-by-step explanation:
3x+4y=5
2x+3y=
-2(3x+4y)=5(-2)
3(2x+3y)=4(3)
-6x-8y=(-10)
6x+9y=12
Add the equations
-6x-8y=(-10)
+ 6x+9y=12
-----------------
0x+y=2
y=2
Substitue y into an equation
6x+9(2)=12
6x+18=12
6x=-6
x = -1
y = 2
The solution of the inequality is x < -9
<h3>How to solve the inequality for x?</h3>
The inequality expression is given as:
-11 < -18- 7/9x
Add 18 to both sides of the inequality
18 - 11 <- 7/9x
Evaluate the difference
7 <- 7/9x
Multiply both sides by -9/7
-9 < x
Rewrite as:
x < -9
Hence, the solution of the inequality is x < -9
