Answer:
A) 250 / 8 = 31.25
31.25 x 8 = 250 Know you know that one pancake requires 31.25ml of Milk
31.25 x 4 = 125
So 4 pancakes requires 125ml of Milk
B) 5 / 8 = 0.625
0.625 x 8 = 5 So just like last time, you know that 0.625g of butter is required to make 8 pancakes
0.625 x 12 = 7.5g of Butter
So 12 pancakes requires 7.5g of butter.
Hope this makes sense !
Answer:
exactly one, 0's, triangular matrix, product and 1.
Step-by-step explanation:
So, let us first fill in the gap in the question below. Note that the capitalized words are the words to be filled in the gap and the ones in brackets too.
"An elementary ntimesn scaling matrix with k on the diagonal is the same as the ntimesn identity matrix with EXACTLY ONE of the (0's) replaced with some number k. This means it is TRIANGULAR MATRIX, and so its determinant is the PRODUCT of its diagonal entries. Thus, the determinant of an elementary scaling matrix with k on the diagonal is (1).
Here, one of the zeros in the identity matrix will surely be replaced by one. That is to say, the determinants = 1 × 1 × 1 => 1. Thus, it is a a triangular matrix.
5 buckets at $2.89 = 5($2.89) = $14.45
10 brushes at $7.91 = 10($7.91) = $79.10
48 towels at $0.36 = 48($0.36) = $17..28
These three added together makes $110.83. This leaves us $144.08-$110.83=$33.25 for the cost of the case of air fresheners.
Of means multiply.
30%=0.3
30*0.3=9
