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.
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)

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
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

Step-by-step explanation:
The ceiling of Katie’s living room is a square that is 20 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Katie can buy rolls that each contain 8 ft of crepe paper. What is the minimum number of rolls she should buy? Show your work.
The room is a square, meaning all four sides are 20ft long.
Because we know all the side lengths, we can find the perimeter of the square by adding the side lengths together.
(20 + 20 + 20 + 20) = 80
Now that we know the perimeter, we have to match this number to the feet of crepe paper.
We can find this by dividing the total length needed by the length a single roll provides.
80 / 8 = 10
Therefore, we know that Katie will have to buy a minimum of 10 rolls if she wants to cover the entire perimeter of the room.
Hope this helps! :)
Katie will need to buy 18 rolls of crepe paper to cover the perimeter and diagonal of her living room ceiling. She calculates the perimeter as 80 ft and the total diagonal length as 56.6 ft, summing up to 136.6 ft which is then divided by 8 ft per roll.
Katie needs to calculate the amount of crepe paper to cover both the perimeter and the diagonal of her living room's square ceiling. The perimeter of a square is calculated by multiplying the length of one side by four. Since each side is 20 ft, the perimeter is 80 ft (20 ft x 4).
Next, we'll find the length of the diagonal using the Pythagorean theorem, which states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
For a square, the diagonal forms a right-angled triangle with two sides of the square, so the diagonal {d} can be calculated as {d} = {a}² + {a}²)^{0.5}, where extit{a} is the length of one side.
Thus, the diagonal is (20² + 20²)^{0.5} ft = (400 + 400)^{0.5} ft = \\(800)^{0.5} ft = 28.28 ft, which we approximate to 28.3 ft for ease of calculation.
Since Katie needs to hang crepe paper from each corner to the opposite corner, she will need twice the length of one diagonal, which is 2 x 28.3 ft = 56.6 ft. Adding this to the perimeter, we get 80 ft + 56.6 ft = 136.6 ft of crepe paper in total.
Dividing the total length by the length of one roll (136.6 ft / 8 ft per roll), Katie finds that she needs 17.075 rolls. Since she can't buy a fraction of a roll, Katie will round up to the nearest whole number, requiring her to buy 18 rolls of crepe paper.

Answer:
correct option is 2187
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]

Using complete sentences, explain the importance of NAFTA. Be sure to discuss the close economic relationship between Canada and the United States.
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.

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
