Since the second angle + first angle is 90 degrees, the third angle must be 90 degrees to complete the 180 degrees in a circle.
Hope this helps!
Answer:
16/45; 4/45; 1125
Step-by-step explanation:
Since you know that 4/9 and 1/5 are used, make them common denominators. So 4/9 would turn into 20/45 and 1/5 would be 9/45. It results in 29/45, but that is the amount spent, so you would subtract 45-29/45, resulting in 16/45. For B, you know that she spent 3/4 of the savings, so you know that 1/4 is not being spent. So use 1/4 multiplied by 16/45 from part A to get 4/45. For C, you know that 4/45 is $100, so I multiplied 45x100 to get 4500 and then divided by 4 to get 4500/4.
Given:
The matrix equation is:

To find:
The value of matrix C.
Solution:
Let
. Then the given equation can be rewritten as




On substituting the values of the matrices, we get




Therefore, the correct option is C.
Answer:
divide the 32 by 4:
then the equation becomes:
8 x 9 x 5 = 360
this is the same as 32 x 9 x 5/4 = 360
First of all, it's not pie. It's pi.
Now, the problem.
Radius is always 1/2 x d (d meaning diameter)
That gives us 5.
The formula is 3.14 x 5^2(h/3)
If you solve it from left to right, you get 130.83
