Answer:60 using ac method
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
because 65 and 79 make up for x
Answer:
Option B: (½•16)⅓
Step-by-step explanation:
The associative property states that we can add or multiply numbers in a group regardless of how those numbers are grouped. And that we will get the same answer.
For example;
x(y•z) = (x•y)z = (x•z)y
Now in our question, we want o evaluate; ½(16•⅓)
Using the associative property, the best expression will be: (½•16)⅓
It's the best expression because the terms in the bracket are easy to multiply out without remainder.
Thus, option B is correct
R = 25 cm = 0.25 m
α = 2.00 rad /s²
T(heta) = 4 π
ω = T(heta)/ t
ω = α t
α t = 4 π / t
t ² = 2 π
t = √ ( 2π ) = 2.5 s
ω = α t = 2 · 2.5 = 5 rad/s
v = ω r = 5 · 0.25 = 1.25 m/s
(1) a (rad) = ω² r = 25 · 0.25 = 6.25 m/s²
(2) a (rad) = v² / r = ( 1.25 )² / 0.25 = 0.15625 / 0.25 = 6.25 m/s²
Answer:
about 100 cm²
Step-by-step explanation:
The side length of the rhombus is 1/4 of the perimeter so is 10 cm. The length of half of the other diagonal will be the length of the leg of a right triangle with hypotenuse 10 and leg 7 (half the given diagonal).
d= √(10² -7²) = √51
Then the area of the rhombus is the product of this and the given diagonal:
A = (14 cm)(√51 cm) ≈ 99.98 cm²
The area of the rhombus is about 100 cm².
