A food production company is choosing between two suppliers of grain. Supplier A sells grain for $5.25 per bushel plus a
delivery fee of $3 per bushel. Supplier B sells B the grain for $6.50 per bushel plus a flat delivery fee of $1,500 each week.
Which supplier would cost more if the production company bought 500 bushels of grain each week?
O Supplier B would cost $625 more than supplier A.
© Supplier B would cost $600 more than supplier A
O Supplier A would cost $875 more than supplier B.
© Supplier A would cost $800 more than supplier B.
Subtraction is a mathematical operation that reflects the removal of things from a collection. Supplier B would cost $625 more than supplier A. Thus, the correct option is A.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
The cost of 500 bushels from supplier A will be,
Cost = ($5.25 × 500) + ($3 × 500)
= $4,125
The cost 500 bushes from supplier B will be,
Cost = $1,500 + ($6.250×500)
= $4,750
Now, the difference between the two suppliers' costs for 500 bushels will be,
Difference = $4,625 - $4,125 = $500
Hence, Supplier B would cost $625 more than supplier A. Thus, the correct option is A.

Answer:
$17131.50
Step-by-step explanation:
23500 decrease 10% =
23500 × (1 - 10%) = 23500 × (1 - 0.1) = 21150
21150 decrease 10% =

what is the measure of easy interior angle of a regular octagon?
The sum of the interior angle is 1080 and each angle measure is 135 degrees.
What is a regular polygon?A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
We have an octagon
In an octagon the number of sides = 8
The sum of the angles in the octagon is given by:
= (n - 2)×180
n = 8
= (8 - 2)180
= 6×180
The sum of the interior angle = 1080
Each angle = 1080/8 = 135 degree
Thus, the sum of the interior angle is 1080 and each angle measure is 135 degrees.

Josh is 31.2 metres away from the Red Pine tree. The angle of elevation from Josh to the top of tree is 48º. His friend Jake also has a Red Pine tree in his backyard. It is half as tall as Josh's tree. Calculate the height of Jake's tree, rounded to two decimal places
The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The height of Jake's tree is 17.325 trees.
What is a Tangent (Tanθ)?The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
Given Josh is 31.2 meters away from the Red Pine tree. The angle of elevation from Josh to the top of the tree is 48º. Therefore, the height of the Josh tree will be,
Tan(48°) = Height of the tree/ Distance between Josh and tree
Height of the tree = Tan(48°) × 31.2 meter = 34.65 meters
Now, Jake's tree is half as tall as Josh's tree. Therefore, the height of Jake's tree is,
Height of Jake's tree = 34.65 meters = 17.325 meters

Answer:
66 m
Step-by-step explanation:
ok so if you think about it, when she runs diagonal she's creating a triangle where she is running along the hypotenuse. we can now use the Pythagorean Theorem a^2 + b^2 = c^2 to solve for the other side with two of them being known.
plug values in
100^2 + w^2 = 120^2
square known values
10,000 = w^2 = 14,400
subtract 10,000 from both sides
w^2 = 4400
take the square root

A pair of parallel lines is cut by a transversal, as shown:
A pair of parallel lines is shown cut by a transversal. Angle x is located in the upper right exterior next to the transversal, and angle y is located in the bottom left exterior corner of the transversal.
Which of the following best represents the relationship between angles x and y?
x = 180 degrees − y
y = 180 degrees − x
x = y
x = 2y
The correct answer is option C which is x = y.
What is the alternate interior angle?The angle formed by the line intersecting two parallel lines is called the alternate interior angle. This two angles are equal in magnitude.
In the given figure we can see that the angle x will be equal to the angle y because of the right opposite angles.
Since two parallel lines are cutting the upper part at x so the same lower part will be also x due to corresponding angles.
Now just right opposite to x there is an angle y so the angles x and y will be equal to each other.
Therefore the correct answer is option C which is x = y.
