Answer:
Y= 3.2b + 100
Step-by-step explanation:
That is the equation needed to find the value of b. since Omar bought the cup at the fixed price of 100 we know that no matter what the answer has to be over 100. So that becomes our Y intercept. 3.2 percent is how much the price inflates every year.
Answer:
George can feed 6 people.
Step-by-step explanation:
Given:
Number of sandwiches = 4
Each person eats two-third of a sandwich.
Therefore, number of persons eating 4 sandwich is given as:

Therefore,

The difference in tallying of expenses from a day to day and month to month is the consistency. in a day to day basis it is consistent the time for a day is 24 hrs it will not change, so you will really know why the expenses goes up or down/ unlike for a month to month it is inconsistent,, some months have 30, 31 or 28 days in a month.
The product that is undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.
<h3>What is the matrix about?</h3>
Looking at the product of matrix, note that to multiply the two matrix, the column of the first matrix needs to have the same or equal to the row of the 2nd matrix.
And in this case (propensity), it is not satisfied by the first option because:
C = 3 x 1 and
O= 2 x 1 matrix
In this case CD is therefore undefined.
So we can say that The product that is undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

x = quarts of 30% acid solution
y = quarts of 65% solution
x + y = 175
Each quart of the 30% solution contributes 0.30x quarts of acid; similarly, each quart of the 65% solution contributes 0.65y quarts of acid. So
0.3x + 0.65y = 0.55*175 = 96.25
That is, the chemist wants 175 quarts of a new mixture with a 55% concentration of acid, which comes out to 95.25 total quarts of acid. The total amounts of acid from either sides of this equation must balance out.
Now solve for x and y:
x + y = 175 ==> y = 175 - x
0.3x + 0.65y = 96.25 ==> 0.3x + 0.65(175 - x) = 96.25
==> 0.3x + 113.75 - 0.65x = 96.25
==> 17.5 = 0.35x
==> x = 50 ==> y = 125
