Answer:
False
Step-by-step explanation:
In order to perform matrix multiplication, the number of columns in the first matrix must be the same as the number of rows in the second matrix.
In this case, the number of columns in the first matrix is 5 and the number of rows in the second column is 3 therefore they aren't the same value, hence, cannot be multiplied
14a. C = 0.09(m - 25) + 50
C = 0.09(80 - 25) + 50
C = 0.09(55) + 50
C = 4.95 + 50
C = 54.95
14b. C = 0.09(m - 25) + 50
85 = 0.09(m - 25) + 50
- 50 - 50
35 = 0.09(m - 25)
0.09 0.09
388⁸/₉ = m - 25
+ 25 + 25
413⁸/₉ = m
14c. The input values that are below 25 does make any sense because it shows that the input values can make the output values decrease itself.
Answer:
Step-by-step explanation:
It may be easier for you to see what's happening here if you'd write the given 1/4 = 3/5s as:
1 3
---- = -----
4 5s
Cross multiplying results in 5s = 12, so that s = 12/5.
If, however, you actually meant 1/4 = (3/5)s, then the solution is quite different:
1/4 = 3/5s => 1/4 = 3s/5, or
1 3s
---- = -----
4 5
Cross multiplication results in 12s = 5, or s = 5/12.
Which did you mean, 1/4 = 3 / (5s) or 1/4 = 3s / 5?
This goes to show how important it is to use parentheses to remove any ambiguity.
Answer: 1.82
Step-by-step explanation:
Density = *Divide the mass by volume.
= 1.82
In a group of 100 people, 2/5 prefer chicken soup, 4/10 prefer to eat hornado, and the rest prefer frying. What part of the group prefers frying ? How many people prefer each type of food ? (thank u google translate)...I guess
2/5 of 100 prefer chicken soup.....so thats 2/5 * 100 = 200/5 = 40 prefer chicken soup.
4/10 out of 100 prefer hornado (I dont even know what that is)...
4/10 * 100 = 400/10 = 40 prefer hornado.
and the rest prefer frying....100 - (40 + 40) = 100 - 80 = 20 (or 1/5) prefer frying
