Aldo went to the store and purchased 8 notebooks for
school. He gave the cashier a $20.00 bill and received
$4.08. Each notebook cost the same amount. Describe the
process you would use to find the cost of each notebook.
Step-by-step explanation:
Start with $20.00.
Subtract the change, $4.08, from $20.00 to find out the amount he spent on 8 notebooks.
Then divide the amount he spent by 8 to find the cost of one notebook.
Answer:
$1.99
Step-by-step explanation:
20 - 4.08 = $15.92
15.92 divided by 8 = $1.99
4. John is packing books into boxes. Each box can hold either 15 small books or 8
large books. He needs to pack at least 35 boxes and at least 350 books, Write a
system of linear inequalities to represent the situation
Answer:
Your system of inequalities is:
x + y ≥ 35
15x + 8y ≥ 350
Step-by-step explanation:
Let x = number of boxes of small books and let y = number of boxes of large books.
Since John needs to pack at least 35 boxes:
(number of boxes of small books) + (number of boxes of large books) (is at least) 35
x + y ≥ 35
Since John needs to pack at least 350 books:
(number of small books packed) + (number of large books packed) (is at least) 350
(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350
15x + 8y ≥ 350

The angle bisectors of AXYZ are XG, YG, and ZG. They meet at a single point G.
(In other words, G is the incenter of AXYZ.)
Suppose DG= 10, ZG= 19, mŁ DYE =96°, and m2 FXG=18°.
Find the following measures.
Note that the figure is not drawn to scale.
Answer:
m∠FXD = 36°
EG = 10
m∠FZG = 24°
Step-by-step explanation:
In triangle XYZ, G is the incenter of the triangle.
Since, m∠FXG = 18°
And m∠FXD = 2(m∠FXG)
= 2 × 18°
= 36°
Since, point G is equidistant from all sides (Property of incenter of a triangle)
Therefore, DG = EG = GF = 10
Since, m∠X + m∠Y + m∠Z = 180°
2(m∠FXG) + m∠DYE + 2(m∠FZG) = 180°
2(18)° + 96° + 2(m∠FZG) = 180°
2(m∠FZG) = 180° - 132°
m∠FZG = 24°

The point at which a company's costs equal its revenues is the break-even point. C represents the cost, in dollars, of x units of a product and R represents the revenue, in dollars, from the sale of x units. Find the number of units that must be produced and sold in order to break even. That is, find the value of x for which C = R. C = 14x + 36,000 and R = 16x.
Answer:
14x+36,000=16x
subtract 14x on both sides
14x+36,000=16x-14x
36,000=2x
divide both sides by 2
36,000÷2=2x÷2
x=18,000

The value of y is directly proportional to the value of x. Given y = 25 when x = 150.
What is the value of y when x = 60?
Enter your answer in the box.
y=
helppp!!
Answer:
Step-by-step explanation:
Y = kx
25 = k150
25/150 = k
0.166 = k
When the value of x = 60
y = (0.166)(60)
y = 9.96
The value of y for x = 60 will be;
⇒ y = 10
What is Proportional?
Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
The value of y is directly proportional to the value of x.
And, Given y = 25 when x = 150.
Now,
Since, The value of y is directly proportional to the value of x.
Hence, We get;
⇒ y = kx
⇒ 25 = k × 150
⇒ 25/150 = k
⇒ k = 1/6
So, The value of y when x = 60 is,
⇒ y = kx
⇒ y = 1/6 × 60
⇒ y = 10
Thus, The value of y for x = 60 will be;
⇒ y = 10
