In order to solve this we will have to apply PEMDAS rule which is as follows:
P
Parentheses first
E
Exponents (ie Powers and Square Roots, etc.)
MD
Multiplication and Division (left-to-right)
AS
Addition and Subtraction (left-to-right)
7+8(3.2.2)
Step 1:
Here we will solve the parenthesis first :
multiplying 3.2.2 =12
so we have 7+8(12)
Step 2:
now we multiply 12*8 here
12*8=96
7+96
Step 3:
addition of 7 and 96 gives us 103
Answer : 7+8(3.2.2) = 103
You would do
tan 50°= x/6
6 tan 50 = x
x= 7.15, but rounded would be 7.2
so the answer is C
Answer:
T maximum=T average -7.8 seconds
T minimum=T average +7.8 seconds
Step-by-step explanation:
Calculation for the equation that can be
use to find the maximum and minimum times for the track team
Using this equation to find the maximum times for the track team
T maximum=T average -7.8 seconds
T maximum=64.6 seconds-7.8 seconds
Using this equation to find the minimum times for the the track team
T minimum=T average +7.8 seconds
T minimum=64.6 seconds +7.8 seconds
Therefore the equation for the maximum and minimum times for the track team are :
T maximum=T average -7.8 seconds
T minimum=T average +7.8 seconds
