Bill's Apparel and Bud's Apparel are two sporting goods retailers. Bill's want to buy 360 small jerseys, 540 medium jerseys, and 300 large jerseys, while Bud's want to buy 240 small jerseys, 600 medium jerseys, and 360 large jerseys. The two dealers from which they are looking to buy their jerseys are Zest Athletics and Zeal Sporting Wear. Zest charges $14 for small jerseys, $18 for medium jerseys, and $21 for large jerseys. Zeal charges $16 for small jerseys, $18 for medium jerseys, and $19 for large jerseys. Use matrix multiplication to find the dealer each retailer should choose for its purchase.
Answer:
D
Step-by-step explanation:
Doing the math, For Bill's to buy it's clothes from Zest, it would take $21060,
while it would take $21180 from Zeal. So Bill's wants Zest.
Bud's price for Zest is $21720, and for Zeal is $21480. Bud's Wants Zeal.
Bill should purchase from Zest and Bred should purchase from Zeel.
What is matrix multiplication?
Matrix multiplication is a binary operation that creates a matrix from two matrices in mathematics, especially in linear algebra. The first matrix's columns must have the same number of rows as the second matrix's rows in order for matrices to be multiplied.
Bud's Apparel and Bill's Apparel are two stores that sell athletic items. In contrast to Bud, who wants to purchase 240 small jerseys, 600 medium jerseys, and 360 large jerseys, Bill wants to purchase 360 small jerseys, 540 medium jerseys, and 300 large jerseys. They are looking to purchase their jerseys from Zest Athletics and Zeal Sporting Wear, respectively. Small, medium and large jerseys cost $14, $18, and $21, respectively, from Zest. Small, medium and large jerseys cost $16, $18, and $19, respectively, from Zeal. From matrix multiplication.
For bill,
if bill buys from zest: 14* 360 + 18* 540 +21*300 = 21060
if bill buys from zeel: 16*360 + 18* 540 + 19*300 = 21180
Since 21060<21180
thus bill should buy from the zest
For bud
if bud buys from zest: 14* 240 + 18* 600 +21*360 = 21720
if bud buys from zeel: 16*240 + 18* 600 + 19*360 = 21480
Since 21720 > 21480
thus bud should buy from the zeal
Therefore, Bred should buy from Zeel, and Bill should buy from Zest.

Type the expression that results from the following steps:
start with x, divide by 3, then subtract 6
ASAP needs to be answered
Answer:
The expression is [tex]f (x) = \frac{x}{3} - 6[/tex]
Step-by-step explanation:
Step(i):-
Given variable start with 'x'
The variable 'x' is divided by '3' so [tex]\frac{x}{3}[/tex]
Step(ii):-
The variable 'x' is divided by '3' so [tex]\frac{x}{3}[/tex] and after that subtract '6'

Step-by-step explanation:
A square is a quadrilateral with all four angles right angles and all four sides of the same length. So a square is a special kind of rectangle, it is one where all the sides have the same length. Which means, every square is a rectangle because it is a quadrilateral with all four angles right angles.
Answer:
i think a rectangle is a type of square

becuase you can put a square into a rectangle but rectangle cant go into a square, a rectangle is bassicly just an elongated square
find the scale factor between each pair of similar shapes
Answer:
Step-by-step explanation:
For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor. A scale factor of 2 means that each side of the larger figure is twice as long as its corresponding side is in the smaller figure.

A company makes 140 bags.
21 of the bags have buttons but no zips.
25 of the bags have zips but no buttons.
45 of the bags have neither zips nor buttons.
How many bags have zips on them?
A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object. The total number of bags that have both zips and buttons is 49.
What is a set?A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.
Given that A company makes 140 bags. 21 of the bags have buttons but no zips. 25 of the bags have zips but no buttons. 45 of the bags have neither zips nor buttons.
Now, we can write the following things about the given condition,
Total number of bags, s = 140
Bags with Only zips, only Z = 25
Bags with only buttons, only B = 21
Bags with neither or them, Z'∩B' = 45
Now, the total number of bags that have both of them is,
Z∩B = s - only Z - only B - Z'∩B'
= 140 - 25 - 21 - 45
= 49
Hence, the total number of bags that have both zips and buttons is 49.

Answer:
Slope of the line is -1.2
Option B is correct option.
Step-by-step explanation:
We need to find slope of the line with given points (4, 10.5) and (8,5.7)
The formula used to calculate slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points given are: (4, 10.5) and (8,5.7)
We have [tex]x_1=4,y_1= 10.5x_2=8,y_2=5.7[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5.7-10.5}{8-4}\\Slope=\frac{-4.8}{4}\\Slope=-1.2[/tex]
So, Slope of the line is -1.2
Option B is correct option.

In circle G with m \angle FGH= 82m∠FGH=82 and FG=7FG=7 units, find the length of arc FH. Round to the nearest hundredth.
The arc length of FH from the given circle is 10.1108 square units.
In the given circle, m∠FGH=82° and FG=7 units.
The formula to find the arc length of a circle is θ/360° ×2πr.
Here, θ=82° and r=7 units
Now, arc length = 82°/360° ×2×3.14×7
= 0.23×2×3.14×7
= 10.1108 square units
