Answer: 82°
Step-by-step explanation:
<CDE = far arc - near arc / 2
i.e
<CDE = arcCBE - arcCE / 2
arcCE = 98°
arcCBE = 360° - 98° = 262°
<CDE = 262° - 98° / 2
<CDE = 164 / 2
<CDE = 82°
Therefore the measure of < CDE is 82°
Without taking out the cost that would be given to the author and publisher it would be $25,893, you just multiply 9.45 by 2,740
An ordered pair (x,y) is a solution to a system of equations if it makes all the equations true.
Let's check whether (–1, 5) makes the equations true.
Plugging –1 in the first equation for x and 5 in for y, we get
–1 + 5 = 4: TRUE
Plugging –1 in the second equation for x and 5 in for y, we get
–1 – 5 = –6: TRUE
Since it makes both the equations true, it's a solution to the system of equations. So the answer choice is D, the 4th one.
Answer:
76.
Step-by-step explanation:
It is given that N is a 2-digit number.
Last two digits of N^2 is the same as N.
We know that, a number is even if it ends with 0,2,4,6,8.
If 0 is in end then we get two zeros in the square of that number.
It is clear that, number should ends with 6 to get the same number at the end.
It is clear that last two digits of (76)^2 is the same as 76.
Therefore, the required number is 76.
