Answer:
11 inches
Step-by-step explanation:
square root of 121 = 11
Answer:
(5-2a+6b)/2
Step-by-step explanation:
According to PEMDAS, we would multiply 2 by (a+3b) first. This would equal 2a+6b. Since this is being subtracted from 5, the numerator would equal 5-2a+6b. This would bring the simplified answer to (5-2a+6b)/2
24+60=84>66
60+66=126>24
66+24=90>60
Therefore, the lengths are the sides of a triangle because the sum of lengths of two sides must be greater than the third side. All the sum of length of 2 sides are greater than the third side.
1. Area of triangle
1/2(10)(12)=60
There are two triangles, so multiply by 2
=120
2. Find area of the rectangles
This is an isosceles triangle, so the two rectangles are congruent
(2)(13)(3)=78
3. Find area of bottom rectangle
10(3)= 30
4. Add everything up
120+ 78 + 30= 228
Therefore the surface area of this prism is 228
I hope i helped :)
Answer:
Option B is correct.
Step-by-step explanation:
We need to find the value of S in cos S = 0.9092
cos S = 0.9092
To find value of S we will find cos^-1(0.9092) i.e
S = cos^-1 (0.9092)
S = 24.6 °
So, the measure of the angle to the nearest tenth of a degree of cos S = 0.9092 is 24.6°
So, Option B is correct.
