Answers
Answer:
4x(x-10)(x+10)
Step-by-step explanation:
4x^3-400x
Factor out 4x
4x(x^2-100)
We know that x^2-100 is the difference of squares
a^2 - b^2 = (a-b)(a+b)
4x(x^2-100)= 4x(x^2 -10^2)
4x(x-10)(x+10)
A car wash company charges a $4 initial fee, plus $1 for each car wash. Which equation
represents this situation?
Answers
Answer:
x+4
Step-by-step explanation:
Equation for the situation will be y = x + 4.
Given in the question,
"A car wash company charges $4 initial fee plus $1 for each car wash"
Let the number of car washes = x
Cost of 'x' car washes = $x
Total fee (with initial fee) for 'x' car washes = $(x + 4)
Therefore, equation for the total amount 'y' will be,
y = x + 4

A. $7,000
B. 18,750
C. 25,750
D. 128,750
I NEED HELP PLEASE
Answers
Answer:
La respuesta es la C
Step-by-step explanation:
Primero tienes que hacer el 25% de ambas cantidades y luego sumarlo
The required, tax would be $25,750 if the Tanners file jointly.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Assuming that the tax rate of 25% applies to their combined taxable income, here's how to calculate their taxes if they filed jointly:
Calculate their combined taxable income:
$75,000 + $28,000 = $103,000
Calculate their tax liability based on their combined taxable income: $103,000 x 0.25 = $25,750
Therefore, the answer is C. $25,750, if the Tanners file jointly.

Due to the vertical angles theorem, which states that d and 39.2 are symmetrical, that means that d is the exact same measure, therefore d is 39.2° as well!
Answer:
39.2
Step-by-step explanation:
this is a vertical angle
a vertical angle is when each of the pairs of opposite angles made by two intersecting lines.
The line segments that connect 2nd base to 1st base' & 2nd base to 3rd base form a right angle. Marcus on 3rd base and he is 90ft from Jean who is on 2nd base. Jean is 90ft from Joel who is on 1st base. How far, in feet, is Marcus from Joel?
A. 45
B. 90
C. 90√2
D. 90√3
Answers
Answer: The correct answer is option C; 90√2
Step-by-step explanation: The line segments are labelled as base 1, base 2 and base 3 respectively. This we shall call point 1, point 2 and point 3. These three points form a right angle. Also we have been told that Marcus is on point 3 and Jean is on point 2. They are both 90 feet apart. Also Joel is on point 1 and he is 90 feet away from Jean. The unmeasured distance therefore is from point 1 to point 3, which is the distance from Joel to Marcus (or Marcus to Joel).
The distance from point 1 to point 3 is the hypotenuse of the right angled triangle derived. Using the Pythagoras' theorem, the distance from Joel to Marcus (or JM) is calculated as follows;
JM² = JC² + JL²
Where JM is the distance between Joel and Marcus (hypotenuse), JC is the distance from Jean to Marcus and JL is the distance from Jean to Joel.
JM² = 90² + 90²
JM² = 8100 + 8100
JM² = 16200
Add the square root sign to both sides of the equation
√JM = √16200
JM = √100*√81*√2
The right hand side of the equation can be further solved as
JM = 10*9*√2
JM = 90√2
Therefore the distance between Marcus and Joel is calculated as 90√2 feet
For the inequality, -4x + 5 >-5
Decide whether the solution is represented
by x < 2.5 or x > 2.5
I NEED THE ANSWER ASAP PLEASE
Answers
Answer:
x<2.5
Step-by-step explanation:
-4x +5>-5
-4x>-5-5
-4x>-10
x<10/4(on multiplying (-)ve sign both the sides inequality changes)
x < 2.5
The inequality -4x + 5 > -5 simplifies to x < 2.5 after isolating the variable and dividing by -4, which also reverses the inequality sign.
Explanation:To solve the inequality -4x + 5 > -5, we first isolate the variable on one side:
Add or subtract constants from both sides of the inequality as needed.Divide or multiply both sides by the coefficient of the variable, taking care to reverse the inequality sign if you multiply or divide by a negative number.Let's solve the inequality step-by-step:
Add 5 to both sides to get -4x > -10.Divide both sides by -4, remembering to reverse the inequality sign, so x < 2.5.Therefore, the solution to the inequality is x < 2.5.

Using complete sentences, explain the importance of NAFTA. Be sure to discuss the close economic relationship between Canada and the United States.
Answers
NAFTA as an organization is very important for the three North American economies, the USA, Canada, and Mexico. It is basically a regional trade organization which has lifted the borders when it comes to trade, thus enabling free movement of goods between these three nations. This has resulted in rise of the economies of all three nations, as there were no trade barriers between them anymore. The companies where able to move their facilities and to operate in each of these countries, which brought them larger profits. The Canadian and the US economies became almost like one, as the companies managed to operate in both places, and to become major players in the market, this especially goes for the US companies that made Canada their home terrain.
Answer:
NAFTA eliminates almost all barriers to trade and investment between the three North American countries and includes provisions for the protection of intellectual property rights.

A steel plate has a length of 1.5 feet, a width of 1 foot, and a thickness of 3/4 inch. A drill makes a hole in the plate with a 1-inch diameter. What is the volume of the steel plate? Round your answer to the nearest cubic inch.
Answers
Answer: 1 ft3
Step-by-step explanation:
Hi, to answer this question, first we have to calculate the volume of the rectangular plate:
Volume of a rectangular prism: width x length x height (thickness)
Replacing with the values given:
V = 1 x 1.5 x 3/4= 1.125 ft3
Now, we have to calculate the volume of the hole:
Volume of a cylinder = π (diameter/2)^2 x height( thickness of the plate)
V = π (1/2)^2 (3/4) = 0.59 ft3
Finally, we have to subtract the volume of the hole to the volume of the plate:
1.125-0.1875 =0.53 ft3 = 1 ft3 (rounded)

Total surface area is 2,185.44 square inches.
lateral surface area is 640.56 square inches
Step-by-step explanation:
Given
radius of cylinder = 12 inches
height of cylinder = 17 inches
we will us value of pi as 3.14
surface area for cylinder consist of two part
1. lateral surface area which is gven by [tex]2\pi rl[/tex]
where r is radius of cylinder and l is height of cylinder
Thus, lateral surface area for given cylinder is
[tex]2\pi rl\\ =>2* 3.14*12*17\\=> 1281.12[/tex]
Thus, lateral surface area for given cylinder is 1281.12 square inches.
_________________________________
second part of surface area is area of two base (upper and lower) of cylinder.
area of base is given by area of circle [tex]\pi r^2[/tex]
[tex]area \ of \base = \pi r^2 = 3.14*12^2\\=>area \ of \base = 3.14*144 = 452.16[/tex]
This, area of base is for one base of cylinder
since there are 2 base
area of both base will be = 2* area of one base
= 2*452.16 = 904.32.
Thus, area of base is 904.32 sq. in.
_______________________________________
Total surface area of cylinder = area of two base+ lateral surface area of cylinder = 1281.12 square inches + 904.32 square inches
= 2,185.44 square inches.
Thus, total surface area is 2,185.44 square inches.
lateral surface area is 640.56 square inches
but option which is closest to calculated value is 2187.
Thus, correct option is 2187
___________________________________________
Note: this problem can be directly solved using formula
total surface area for cylinder = [tex]2\pi r^2 + 2\pi rl[/tex]
