Answer:
(B) a square matrix
Step-by-step explanation:
The given Equations are:
,
and
Which can be written as:
![\left[\begin{array}{ccc}3&-2&2\\7&3&-26\\-1&-11&46\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-2%262%5C%5C7%263%26-26%5C%5C-1%26-11%2646%5Cend%7Barray%7D%5Cright%5D)
Thus, it is a matrix with 3 number of rows and 3 number of columns, therefore the matrix which has same number of rows and columns is a square matrix, thus, a square matrix can be form using the given system of linear equations.
The weight (y) will always be positive, the number of balls (x) too. So without the bucket, the function would be:
y = 1.6x
Now we have to add the weight of the bucket which is 2lb, or the same 32oz.
So the function results:
y = 1.6x + 32 (oz.)
If there is 1 ball, the weight is 1.6+32 = 33.6 oz. If there are no balls, the weight is 0 + 32 = 32 oz.
It is very important that all terms in the equation are in the same units, oz. in this case. Otherwise, if you do not translate lb. to oz. the resulting equation will be wrong.
If you need the equation expressed in lb., you only need to multiply the equation by 1lb/16oz:
y = = 0.1x + 2 (lb.)
<span>4. Unit rate implies how much in one hour. If 306 miles is in 10 hours, in one hour, it will be just one-tenth of 306 miles. So divide 306 by 10. To divide by 10, just place a point before one digit from the right. So the answer will be 30.6 milers/hour.
5. Unit rate here implies how much in one month. If 33.6 gallons is in 6 months, in one month, it will be just one-sixth of 33.6 gallons. So divide 33.6 by 6. The answer will be 5.6 gallons/month.</span>
The Prism has a larger surface area than the pyramid.
<h3>What is
area?</h3>
Area is the amount of space occupied by a two dimensional shape or object.
Surface area of Prism = 2 * base area + 4(base length)(height)
Surface area of Prism = 2(6 * 6) + 4(6)(4) = 168 in²
Surface area of pyramid = (base area) + 2(base length)(slant height)
Surface area of pyramid = (6 * 6) + 2(6)(5) = 96 in²
The Prism has a larger surface area than the pyramid.

complement angle meabs 90° so,
90° - 48°
= 42°
hence the complement angle of 48° is 42°
