The answer is 3/4 and it was already simplified
Answer:
21 scoops
Step-by-step explanation:
We will divide the amount the recipe calls for, 3 1/2 cups, by the size of the scoop, 1/6 cup:
3 1/2 ÷ 1/6
Convert the mixed number to an improper fraction. Multiply the whole number by the denominator and add the numerator; 3(2)+1 = 6+1 = 7; this makes it 7/2:
7/2 ÷ 1/6
To divide fractions, flip the second one and multiply:
7/2 × 6/1
42/2 = 21
Answer:
x < 50
Step-by-step explanation:
No more means that it cannot equal 50. Therefore we can remove the 1st two options.
We now have the 3rd option and 4th option to choose from.
The 4th option is incorrect because the inequality is saying that a number is greater than 50.
∴ x < 50 is our answer.
Answer:
intervals (-3,-1) and (0,+infinity)
Step-by-step explanation:
if f'(x)>0 then f is increasing
Answer:
See explanation below
Step-by-step explanation:
The zero matrix is the matrix which has m rows and n columns and all its elements are zero, for example:
This matrix has the property that, when applied to a vector, sends it to zero.
On the other hand, the multiplicative identity matrix is an square matrix that has 1's in its diagonal and zero's everywhere else.
This matrix has the property that when multiplied by another one, doesn't change the first matrix (leaves things the same way as they were, it's like multiplying by one)
For example, a 3 x 3 multiplicative identity matrix would be:
