Answer:
I'm not to sure but I think it's 39 11/20
Step-by-step explanation:
1/5 + 1/4 you have to get a common denominator which would be 20 and then you add the numerators to get 9. Then you would subtract 40 from 9/20 and have to get the common denominator again which would be 800/20 - 9/20 which is 751/20 simplified to 39 55/100 simplified even more to 39 11/20. I haven't done fractions for a while so it might be wrong. I hope I helped!
Answer:
The determinant is 15.
Step-by-step explanation:
You need to calculate the determinant of the given matrix.
1. Subtract column 3 multiplied by 3 from column 1 (C1=C1−(3)C3):
![\left[\begin{array}{ccc}-25&-23&9\\0&3&1\\-5&5&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-25%26-23%269%5C%5C0%263%261%5C%5C-5%265%263%5Cend%7Barray%7D%5Cright%5D)
2. Subtract column 3 multiplied by 3 from column 2 (C2=C2−(3)C3):
![\left[\begin{array}{ccc}-25&-23&9\\0&0&1\\-5&-4&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-25%26-23%269%5C%5C0%260%261%5C%5C-5%26-4%263%5Cend%7Barray%7D%5Cright%5D)
3. Expand along the row 2: (See attached picture).
We get that the answer is 15. The determinant is 15.
Answer:
100
Step-by-step explanation:
Answer:
120
Step-by-step explanation:
Solution for What is 8 percent of 1500:
8 percent *1500 =
(8:100)*1500 =
(8*1500):100 =
12000:100 = 120
Now we have: 8 percent of 1500 = 120
Question: What is 8 percent of 1500?
Percentage solution with steps:
Step 1: Our output value is 1500.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 1500 = 100%
Step 4: Similarly, x = 8%
Step 5: This results in a pair of simple equations:
1500 = 100% (1).
x = 8% (2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
<u>1500</u> = <u>100%</u>
x 8%
Step 7: Again, the reciprocal of both sides gives
<u> x </u> = <u> 8 </u>
1500 100
x = 120
Therefore, 8% of 1500 is 120
