Answer:
The area is 83.905 cm^3
Step-by-step explanation:
The total ratio is 9 + 7 + 6 = 22
So the length of the sides are as follows;
9/22 * 44 = 18 cm
7/22 * 44 = 14 cm
6/22 * 44 = 12cm
we can use Heron’s formula to find the area of the triangle
we find a first
s = (a + b + c)/2 = (18+14+12)/2 = 44/2 = 22
Mathematically, the Heron’s formula is as follows;
A = √s(s-a)(s-b)(s-c)
where a, b and c are 18,14 and 12 respectively
Plugging the values, we have;
A = √22(22-18)(22-14)(22-12)
A = √(22 * 4 * 8 * 10)
A = √(7,040)
A = 83.905 cm^3
Answer:
Step-by-step explanation:
(x+4)² + y² = 1.5²
Answer:
Step-by-step explanation:
To find the value of y, you can create an equation where two parts of the line are equal to the whole line:
Substitute given values:
Solve for y. Simplify parentheses:
Combine like terms to simplify the equation:
Get the variable on one side of the equation and the constants on the other. Add 9 to both sides:
Subtract 9y from both sides:
Isolate the variable. Divide both sides by 10:
The value of y is 2. Insert this value into each line segment value and solve:
:Done
You can check by using:
This statement is true, so the values are correct.
5x+17 = 8x-31
48 = 3x
x = 48/3
x = 16
RS = 5x + 17 = 5*16 +17 = 80 +17 = 97
RS = 97

Answer:
7 years
Step-by-step explanation:
Use the formula I=Prt
Convert 4% to a decimal. 4% = 0.04
1428 = 5100(.04)t
1428 = 204t
1428/204 = 204t/204
t = 7 years
