Answer:
4.761904762 %
Step-by-step explanation:
( 24 ÷ 25.20 ) × 100 = 95.23809524
100-95.23809524 = sales tax percentage
sales tax percentage =
The answer is .277
Why:
Because first of all there are 26 letters in the alphabet then 10 numbers are given. so add those together; 26+10= 36
So 36 is the total and the fraction is 10/36
then divide
10/36= .277 about
Answer:
- determinant: -15
- x = 3; y = 4; z = 1
Step-by-step explanation:
The matrix of coefficients has one row corresponding to each equation. The constants in that row are the coefficients of the variables in the equation. Coefficients are listed in the same order on each row. A missing term is represented by a coefficient of 0.
<h3>coefficient matrix, determinant</h3>
The first attachment shows the coefficient matrix and its determinant.
__
<h3>solution</h3>
The solution to the system of equations can be found by left-multiplying the constant vector by the inverse of the coefficient matrix.
This multiplication is shown in the second attachment. It tells us ...
Answer:
1072.3
Step-by-step explanation:
A hemisphere is half of a sphere, so the volume V of the hemisphere is the volume of the sphere divided by 2.
V = (2/3)*
= (2/3)*
= (2/3)**512
= 1072.3
A^2+b^2=c^2
8^2+b^2=17^2
64+b^2=289
b^2=225
b=15
