Answer:
Lets take all factors into consideration first
The door is a rectangle and the area of a rectangle is length times width
Let the width be w
Let the length be l
Equation length × breadth = area
(w+48)w = 3024
w^2 + 48w = 3024
w^2 + 48w - 3024 = 0
w^2 + 84w - 36w - 3024 = 0
w(w + 84) -36 ( w + 84) = 0
(w + 84) (w - 36) = 0
w + 84 = 0 AND w - 36 =0
w = -84 and w = 36
Since width cannot be negative, the right answer is 36
How did I get 84 and 36? Well, I had to factorize 3024 and since 84 times 36 is 3024 and 84 minus 36 is 48, I chose them.

Mark works 24 hours a week and earns £11.63.
Calculate Mark's weekly basic pay and then find his annual salary
Weekly pay = amount per hour x number of hours:
24 x 11.63 = 279.12
Annual salary = weekly pay x 52 weeks:
279.12 x 52 = 14,514.24

Step-by-step explanation:
Answer:
The area of the shape is 21.87 square feet.
Step-by-step explanation:
Assuming the indent on the right is a perfect semicircle, then you need only subtract the area of the semicircle from the area of the rectangle.
The rectangle is six feet on both directions, giving it an area of 36 square feet.
The circle then has a radius of 3 feet. The area of a circle is equal to πr², so in this case, π × 9. Using a pi value of 3.14, nine times that is 28.26. We only want half the circle's area though, giving us 14.13.
Now we can subtract that semicircle from the square giving us:
36 - 14.13 = 21.87
So the total area is 21.87 square feet.
What is the value of y in the parallelogram below?
5y"
654
O A. 110
O B. 60
O c. 13
D. 23
Answer:
D. 23
Step-by-step explanation:
5y = [360 - (65 x 2)] / 2
5y = [360 - 130] / 2
5y = 230 / 2
5y = 115
y = 23

An apartment manager would like to survey a sample of residents to determine whether there may be interest in building a pool what is the best way that the apartment manager could select he sanple
Answer: b. randomly select people from all residents of the apartment building.
Step-by-step explanation:
This issue at hand concerns all residents of the building so the apartment manager should randomly select people to participate in the survey from the entire population of all the residents of the apartment building.
Selecting only those who have children would not be representative of the whole population as there will be people with less or more children than 5 and some would not have children. Option C and D are wrong because only current residents should be included.

Find all points on the curve y = cos x, 0 ≤ x ≤ 2π, where the tangent line is parallel to the line y = -x.
Answer:
90⁰
Step-by-step explanation:
y=cosx
y'= -sinx
eqñ of tangent is y=-x
slope of tangent =-1
we know...
slope of tangent = y' or derivative of y
-sin x = -1
sin x= 1
x = 90⁰

A car travels 384 kilometers in 4 hours. (with a constant speed) how much time will it take traveling at 144 kilometers?
Answer:
1.5 hours or 90 minutes
Step-by-step explanation:
384 km: 4 hours
divide both sides by 4
96 km: 1 hour
multiply both sides by 1.5
144 km: 1.5 hours
Answer:
it will take 1.5 hrs as u multiply 144 with 4 and divide by 384

7. In a bay the time between high tide and low tide is approximately 6 hours. The first low tide is at 7 a.m. followed by a hide tide at 1 p.m. The depth of the water in the bay at low tide is 5 fathoms which rises to 9 fathoms at high tide. a) Sketch a graph of the depth of the water in the bay over time. Start your graph at 7 a.m. and graph at least on complete cycle. b) Write a function equation for your curve. Let t represent the number of hours after 7 a.m. c) How deep will the water be at 11 a.m?

Explain why this common mistake is wrong. Many people might say that (2, 4) is an intercept of the equation 5x + 2y = 18.
Answer:
Step-by-step explanation:
(2,4) is point lying on the line represented by 5x + 2y = 18.
They are not intercepts.
x-intercept is point where the line crosses the x-axis and so, y-co ordinate at x-intercept is 0.
y-intercept is point where the line crosses they-axis and so,x-co ordinate at y-intercept is 0.
5x + 2y = 18
To find x-intercept, put y = 0 in the equation
5x = 18
x = 18/5
x = 3.6
To find y-intercept, put x = 0 in the equation
2y = 18
y = 18/2
y = 9
x-intercept : (3.6 , 0)
y-intercept :(0, 9)

Find the surface area of the triangular pyramid.
a triangular pyramid - the base has side length 2.5 inches and height 2.2 inches and each face has height 5 inches
Answer:
31.25 in²
Step-by-step explanation:
Surface area of triangular pyramid
Perimeter, P = 4s = 4 * 2.5 = 10 inches
Lateral surface area = 0.5 * P * height = 0.5 * 10 * 5 = 25 inch²
The base area = s² = 2.5² = 6.25 inch²
Hence, surface are ao triangular pyramid ;
Lateral surface area + base area
= 25 inches + 6.25 inch²
= 31.25 in²

find the surface area and volume of a cube with the following dimensions: length 4cm, width 4cm, height 4cm
Answer:
Surface area is 96cm^2, volume is 64 cm^3.
Step-by-step explanation:
Surface area = area of top and bottom + area of left and right + area of front and back.
area of top or bottom = 4×4=16cm^2
area of left or right = 4×4= 16cm^2
area of front or back = 4×4=16cm^2
total surface area = 2(16) + 2(16) + 2(16) = 96cm^2
volume of a cube = length × width × height = 4×4×4 r 64 cm^3.
I want the answer fast plz
Answer:
y=-x/3+2
Step-by-step explanation:
If you graph out 3x-y-7=0, you will get a line that goes through the points (0, -7), and about (2.3, 0). If you graph out y=x/3+2, you have to make sure that this line forms a 90 degree angle on the previous line, thus making this line perpendicular to the previous line.
