Mr. Staley buy 20 binders for his mathematics class.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Mr. Staley has $62 to buy binders for his mathematics class.
And, The cost of each binders = $3
Now,
Since, The cost of each binders = $3
Hence, Number of binders = $62 / $3
= 20.67
Since, We get the remainder 2 and the quotient is 20.
So, we get;
Mr. Staley buy 20 binders for his mathematics class.
Thus, Mr. Staley buy 20 binders for his mathematics class.

A bike wheel is 26 inches in diameter. What is the bike wheel's diameter in millimeters (1 inch = 25.4 millimeters)?
Given that, a bike wheel is 26 inches in diameter.
We need to convert bike wheel's diameter in millimeters .
Since, 1 inch = 25.4 millimeters.
So, to convert 26 into mm we need to multiply 26 each sides of this identity to convert this into mm. Hence,
1*26 inch = 25.4 * 26 mm.
So, 26 inches = 660.4 mm.
So, the bike wheel's diameter is 660.4 millimeters.
Hope this helps you!
The bike wheel's diameter of 26 inches is equivalent to 660.4 millimeters.
To convert a bike wheel's diameter from inches to millimeters,
we have to use the conversion factor, which is,
1 inch = 25.4 millimeters.
Now multiplying the diameter of the bike wheel,
which is given as 26 inches,
by the conversion factor of 25.4 millimeters per inch.
⇒ 26 inches x 25.4 millimeters per inch = 660.4 millimeters
Therefore, the diameter of the bike wheel in millimeters is 660.4 millimeters.
Therefore, we can convert inches to millimeters by multiplying by 25.4, which is the number of millimeters in one inch.
In this case, the bike wheel's diameter of 26 inches is equivalent to 660.4 millimeters.

QUICK HELP! How many terms are in the simplified expression? How many of the terms in the simplified expression are negative?
Expression: 2x^2 - y^2 +5xy - 2y
Final answer:
The simplified expression '2x² - y² + 5xy - 2y' contains four terms, of which two are negative.
Explanation:
The expression given is 2x² - y² + 5xy - 2y To determine how many terms are in this simplified expression, we simply count the distinct variables and constant groupings. In this case, there are four terms: 2x², -y², 5xy, and -2y. Among these, two terms have a negative sign in front of them, indicating that they are negative. Thus, there are two negative terms in the simplified expression.
What value is added to both sides of the equation x2 − 8x = −10 in order to solve by completing the square?−816−44?
Answer:
The correct option is 2. 16 is added to both sides of the equation.
Step-by-step explanation:
The given equation is
[tex]x^2-8x=-10[/tex]
If an expression is defined as [tex]x^2+bx[/tex], then we need to add [tex](\frac{b}{2})^2[/tex] in the expression to make it perfect square.
In the given equation b=-8.
[tex](\frac{b}{2})^2=(\frac{-8}{2})^2=(-4)^2=16[/tex]
We need to add 16 on both the sides to solve by completing the square.
Therefore the correct option is 2. 16 is added to both sides of the equation.

Write the expressions as a difference and simplify it: 17x−13y+8 and 20x+6y.
The two expressions 17x−13y+8 and 20x+6y can be rewritten as a difference to be -3x - 19y + 8.
Explanation:To rewrite the two expressions 17x−13y+8 and 20x+6y as a difference, you can first list them separately and then combine by subtraction.
17x - 13y + 8
and
20x + 6y
. The difference between these two expressions is obtained by performing the subtraction as follows: (17x - 13y + 8) - (20x + 6y). Now, you can simplify this by removing the parentheses and switching the sign of the terms being subtracted, which results in:
17x - 13y + 8 - 20x - 6y
. Finally, you combine like terms, x-terms with x-terms and y-terms with y-terms, ending up with:
-3x - 19y + 8
which is the simplified difference of the two expressions.

Alex and Freddy collect stamps. The number of stamps in Alex’s collection is in ratio 3:5 to the number of stamps in Freddy’s collection. If Freddy gives Alex 10 stamps, the ratio will change to 7:9. How many stamps are in both collections together?
Answer:
160 stamps
Step-by-step explanation:
Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
The new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have
Satellites KA-1212 and SAL-11 have spotted a UFO. Scientists want to determine its distance from KA-1212 so they can later determine its size. The distance between the satellites is 900 km. If KA-1212's camera is focused on SAL-11 , it must rotate 60° to see the UFO. If SAL-11's camera is focused on KA-1212, it must rotate 75° to see the UFO. How far is the UFO from KA-1212? Round your answer to the nearest kilometer.
Answer:
The distance of UFO from KA-1212 is 1229.7 km.
Step-by-step explanation:
We are given that,
Distance between the satellites = 900 km
Angle made by the satellite KA-1212 = 60°
Angle made by the satellite SAL-11 = 75°
So, from the figure below,
The third angle is given by = 180° - (60°+75°) = 180° - 135° = 45°
Then, using the law of sines, we have,
[tex]\dfrac{x}{\sin 75}=\dfrac{900}{\sin 45}\\\\x=\dfrac{900\times \sin 75}{\sin 45}\\\\x=\dfrac{900\times 0.966}{0.707}\\\\x=\dfrac{869.4}{0.707}\\\\x=1229.7[/tex]
Thus, the distance of UFO from KA-1212 is 1229.7 km.Satellites KA-1212 and SAL-11 have spotted a UFO. Scientists want to determine its distance from KA-1212 So, it is 1229.7 km.
What is a law of sine?Law of sines is a formula relating the length of the sides of a triangle to the angles of the triangle.
It is given that
Distance between the satellites KA-1212 and SAL-11 = 900 km
Angle made by the satellite KA-1212 = 60°
Angle made by the satellite SAL-11 = 75°
So, the third angle is given by
= 180° - (60°+75°)
= 180° - 135°
= 45°
Using the law of sines, we get
x/sin75° = 900/sin 45°
x = 900 × sin75°/ sin 45°
x = 900 × 0.966/ 0.707
x = 1229.7
Thus, the distance of a UFO from KA-1212 is 1229.7 km.
