Answer:
17/9 or 1 8/9 if you are looking for a mixed fraction
Step-by-step explanation:
1 7/9 + 4/36
16/9 + 4/36
Multiply 16/9 by 4/4 to get the same denominator as 4/36
64/36 + 4/36
68/36 = 17/9 = 1 8/9
Answer:
t=(37+root89)/32,(37-root89)/32
Step-by-step explanation:
Solve the equation:
23=3+37t-16t^2
3 equivalent ratios or 5/2
10 /4
20/8
30/12
(2y² + 7y + 11) - (8y² - 5y + 7) you can distribute the negative sign to the second expression and then combine the like terms
new expression: (2y² + 7y + 11) (-8y² + 5y - 7)
2y² and -8y² equals -6y²
7y and 5y equals 12y
11 and -7 equals 4
The answer is -6y² + 12y + 4
Answer:
A = 23.6 units^2
Step-by-step explanation:
Let the base be 8 (as shown).
Find the height of the triangle: Find the supplement of the 100 degree angle; it is (180 - 100), or 80 degrees. The side "opposite" this 80-degree angle is the height of the triangle:
height
sin 80 degrees = ---------------
6
and so the height of the triangle is h = 6 sin 80 degrees, or 5.91 units.
The area of the triangle is found using A = (1/2)(base)(height), which here amounts to:
A = (1/2)(8 units)(5.91 units), or
A = 23.64 units^2, or A = 23.6 units^2
