To find how many cm are in a ft, you have to use the method of unit rate:
so we know that 12 in. equals a ft. so,
1 ft
------
12 in.
and 2.25 cm equals an in. so,
1 in.
-------
2.54cm
then we put the rates together and get:
1ft 1 in.
---- X -------................we cancel out the in. units and get:
12 in. 2.54 cm
Solve and get 1 ft = 30.48 cm
IF sides AC and BC are the 'legs' of the triangle, then the length of the 3rd side is
√ (5² + 6²) = √(25 + 36) = √61 = 7.81 (rounded)
IF side BC is the longest side (hypotenuse) of the triangle, then the length of
the 3rd side is
√(6² - 5²) = √(36 - 25) = √11 = 3.32 (rounded)
Answer:
82
Step-by-step explanation:
So first you would do PEMDAS ( plz excuse my dear aunt sally)
Parentheses are first so you would do 4+3 which is = to 7
then its multiplication 6*7*2
And your answer is 82
Answer:
10 m/s
Step-by-step explanation:
KE = 0.5mv^2
400 = 0.5(8)(v^2)
100 = v^2
v = 10 m/s
<u>slope intercept form</u>: y = mx + b [ where m is slope and b is y-intercept ]
Here, the "slope is -3" and "y-intercept is 9"
