In order to find the are you have to multiply length x width.
In order to find the perimeter you have to add up all the sides together.
Answer: The expression which must fill in each blank space to complete step 3 is; Choice B; Cos(A)Cos(B).
Which expression must fill in each blank space?
From the task content; It follows that the mathematical evaluation is in a bid to derive the Trigonometric identity for Tan (A-B).
From observation, it follows that the required expression is; cos(A)sin(B). This is because upon division of each term by the expression, the result is as in Step 4.
Answer:
8.12
Step-by-step explanation:
Hey There!
When you round to the nearest hundredth you are rounding the number 2 digits away from the decimal point which is 1
remember we base the rounding off of the number after 1 which is 6
5 or more raise the score
so 8.1165 rounded to the nearest hundredth would be
8.12
Answer:
Sam sokey 0.5 hours biking and 3.5 hours walking
Step-by-step explanation:
Here, we want to know the number of hours spent walking and biking
Mathematically; distance = speed * time
Let the number of hours spent walking be x and the number of hours spent biking be y
Mathematically;
x + y = 3 •••(i)
distance spent walking = 4 * x = 4x miles
distance spent biking = 12 * y = 12y miles
4x + 12y = 20
divide through by 2
2x + 6y = 10 ••••••(ii)
From i , x = 4-y
Substitute this into ii
2(4-y) + 6y = 10
8 - 2y + 6y = 10
8 + 4y = 10
4y = 10-8
4y = 2
y = 2/4 = 0.5 hours
The number of hours spent walking = 4-0.5 = 3.5 hours
