Answer: A. 3 x 3 x 3 x 4
Step-by-step explanation: 3 x 3 = 9 x 3 = 27 x 4 = 108
Let S=larger square side and s=smaller square side. The area between the larger and smaller is simple the larger area minus the smaller area. The area of any square being s^2. So our remaining area is:
A=S^2-s^2
A=144-49=95 cm^2
We first find value of tax in dollars.
The difference between the two prices is: 23. 54 - 22 = 1.54
Therefore the sales tax in dollars is 1.54
The tax % will be (amount of tax / original cost price ) × 100
(1.54 / 22) × 100 → (0.07) × 100 = 7
So the tax rate is 7%
We can double check the answer.
7 % of 22 → (7/100) × 22 → 0.07 × 22 = 1.54
22 + 1.54 = 23.54
Answer:
(A)
(B)
(C)
Step-by-step explanation:
The manager ordered 10 lb of tomatoes, 20 lb of zucchini, and 40 lb of onions from a local farmer one week.
(A)
Matrix <em>A</em> represents the amount of each item ordered. It is 1 × 3 matrix.
Then matrix <em>A</em> is:
(B)
Next week the manager increases the order of all the products by 10%.
Then the amount of new orders are:
Tomatoes
Zucchini
Onions
Th matrix <em>B</em> represents the amount of each order for the next week. Then matrix <em>B</em> is:
(C)
Add the two matrix <em>A</em> and <em>B</em> as follows:
The entries of the matrix (<em>A</em> + <em>B</em>) represent the amount of tomatoes, zucchini and onions ordered for two weeks.
