Answer:
Approximately 54.54% of race happened in the first week.
Step-by-step explanation:
We are given the following in the question:
Length of bike race in three weeks = 2,200 miles
Race covered in first week = 1,200 miles
Percentage of race covered in first week =
Thus, approximately 54.54% of race happened in the first week.
Let Surface Area A, a the base edge and h the height:
A = a²+2a√(a²/4+h²)
h=?
pythagorean theorem:
h²=c²-a²
h=√(c²-a²)
h=√(8²-(.7/2)²)= 8
plug it in the above equation A= 11.7ft²
So A is correct
Answer:
C = 12 + 15(x - 4)
C = 15x - 48
Step-by-step explanation:
Let the number of hours = t
The total amount Miguel earns =
C
To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.
C = 12 + 15(x - 4)
Expand the t
C = 12 + 15x - 60
C = 15x - 48
Therefore, an expression for the amount, in dollars, Miguel charges if it takes him t hours to edit a manuscript, where t>4 is given as:
C = 15x - 48
A is correct. Just move the negative sign from in front of the 9 and place it in front of the 4.
The question is asking what will we get if we add 1+1.
Let us use an example to understand this.
Example:
Suppose Amy has 1 ice cream and her brother Ruth has also got one ice cream.
Now if they both finished their ice creams, how many total ice creams were finished.
So we see that 1 and 1 add up to give two ice creams and so two ice creams are finished by them both.
Applying this to our question adding 1 and 1 gives us 2.
Answer : 1+1 =2
