Answer:
-29.988 or if you round up -30
Step-by-step explanation:
1) Convert fractions to decimals
3.6 x (-8.33) = -29.988
Answer: the formula is (A=bh1/2)
Step-by-step explanation: #4 (The triangle)
First let’s find the base length of the triangle.
28 - 16 = 12
Ok now let’s do the real math now
Area = bh1/2
Area = (12)(16)(1/2)
Area = 96
Don’t worry about the slant height it’s just there to trick you
Answer:
C.
Step-by-step explanation:
First finding height using Pythagoras theorem
(H)²=(B)²+(P)²
8.2²=5.4²+P²
P² = 67.24 - 29.16
P² = 38.08
P = 6.2
Now
Volume of cone = (1/3)πr²h
= (1/3)(3.14)(5.4)²(6.2)
= (1/3)(567.9)
= 189.2 cm³
Answer:
B. 30x
D. x(45-15)
Step-by-step explanation:
The distributive property lets you factor out the common factor of x. The sum of coefficients can be simplified to a single coefficient.
45x -15x = x(45 -15) = 30x
The answer is the first choice.
