The answer is B.
Negative numbers are to the far left if you were using a number line, so -1 to the 3rd power is -1. Everything else is positive. 1/4 is the same as 0.25 which is less than positive 1, positive 8.8 is next and the last would be -5 to the 2nd power which is 25.
The answer is, 402m.
Explanation)
A = pi(r)^2
A = pi(8.5)^2
A = 113
//
A = x^2
A = 17^2
A = 289
Now add these two values (289 & 113) together and you'd get 402.
Hopefully, I helped you out!
Answer:
A. 121
Step-by-step explanation:
The sum of the exterior angles is 360°, so you have ...
z + (z +10) + (z -13) = 360
3z -3 = 360 . . . . . collect terms
z -1 = 120 . . . . . . . divide by 3
z = 121 . . . . . . . . . add 1
Answer:
B {6, 6, 7}
Step-by-step explanation:
Which set of numbers may represent the lengths of the sides of a triangle? (A) {2,5,9} (B) {6,6,7} (C) {6,4,2} (D) {7,8,1}
For a given triangle with 3 sides, the sun of the length of any two sides must be greater Than the third side. This can be expressed mathematically as;
Let the side be ;
x, y and z
Then:
x > (y + z) or
y > (x + z) or
z > (x + y)
For A{2,5,9}
(2 + 5) < 9 (does not meet criteria)
For B {6,6,7}
(6 +6) > 7
(7 +6) > 6
Meets all criteria
For C {6,4,2}
(4 +2) is not greater Than 6 (does not meet criteria)
For D {7,8,1}
(7 +1) is not greater Than 8 ( does not meet criteria)
Hi,
Answer: - 15
<u>My work:</u> To easily achieve this problem take your number -11 and add it with negative 4. When you do this you get your answer - 15. This problem can be easily solved in 2 steps.
<u><em>My Numerical work:</em></u>
1. - 11 + -4
2. -15
