90 x 4 - 14 / 2 + 10^2 / 5 x 2
For this expression, you would use the method PEMDAS.
(Parentheses Exponents Multiplication Division Addition Subtraction)
The first one available in this expression is Exponents (10^2=100)
90 x 4 - 14 / 2 + 100 / 5 x 2
Then Multiplication (90 x 4 = 360 and 5 x 2= 10)
360 - 14 / 2 + 100 / 10
Next is Division (14 / 2 = 7 and 100 / 10 = 10)
360 - 7 + 10
Now Addition or Subtraction (whichever one is first from left to right)
353 + 10
90 x 4 - 14 / 2 + 10^2 / 5 x 2 = 363
Here's a couple of equivalent ratios
3:1, 6:2, 12:4, 15:5, 30:10
Answer:
Length of arc=4π
Step-by-step explanation:
Length of arc=¤/360 x 2xπxr
Where:
¤=72
r=10
Length of arc=72/360 x 2xπx10
Length of arc=0.2 x 20π
Length of arc=4π
The answer is 88. Just divide the largest number into the smallest one. Hope this helps!
U can find the reciprocal of a number by flipping the number.
example : the reciprocal of 1/5 is 5/1....the reciprocal of 2/3 = 3/2.
the reciprocal of x = 2/7.....that means x = 7/2
5 / (7/2) = when dividing fractions, flip what u r dividing by, then multiply
5 * 2/7 =
10/7 or 1 3/7 <==
