Answer:
19.10
Step-by-step explanation:
If im correct,
You subtract 10 and 5. Wich is 5. Then multiply that by 3.82.
Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h
23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified
24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values
.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.
What is 75-50, then you subtract that answer from 180, because if it’s a triangle, all 3 sides should equal to 180
Answer:
The correct matrices are:
Matrix:
7 1 5
1 5 7
5 7 1
all diagonal elements of A^2 are: 7^2 + 1^2 + 5^2
Matrix:
9 18 27
27 -9 18
18 27 9
all diagonal elements of A^2 are: 9^2 + 27*18 + 18*27 or (-9)^2
Matrix:
8 1 6
6 8 1
1 6 8
all diagonal elements of A^2 are: 8^2 + 6*1 + 1*6
Answer:
2and19/90
Step-by-step explanation:
-2/3*3/5= _2/5
-2/5+5/2-(2/3×1/6)
-2/5+5/2-1/9
21/10-1/9
=199/90
=2/19/90
