Find the area of the polygon shown. Enter the number into the box.
ft? 1 ft 4 ft 4 ft
Answers
Answer:
The area of the trapezium is 18 ft²
Step-by-step explanation:
Given;
Two parallel sides of the polygon as follows;
The first parallel side = 1 ft + 4 ft = 5 ft
The second parallel side = 4 ft
If this polygon is rotated 90 degrees, it forms a trapezium with a height of 4 ft.
The area of a trapezium is calculated as;
[tex]A rea= \frac{1}{2} (sum \ of \ parallel \ sides) \times height\\\\Area = \frac{1}{2} (5 \ + \ 4) \times 4\\\\Area = 18 \ ft^2[/tex]
Therefore, the area of the trapezium is 18 ft²

16 In a flower fertilisation experiment, the
number of pink flowers grown is twice that
of red flowers. The number of white flowers
grown is 3 more than that of red flowers.
The number of white flowers grown is
37 fewer than that of pink flowers. Find the
total number of flowers grown.
Answers
Answer:
The total number of flowers grown is 163.
Step-by-step explanation:
Since in a flower fertilization experiment, the number of pink flowers grown is twice that of red flowers, and the number of white flowers grown is 3 more than that of red flowers, the number of white flowers grown is 37 fewer than that of pink flowers, to find the total number of flowers grown the following calculation must be performed:
P = 2R
W = R + 3
W = P - 37
W = W
R + 3 = 2R - 37
R + 3 + 37 = 2R
40 = 2R - R
40 = R
P = 2 x 40 = 80
R = 40
W = 40 + 3 = 43
80 + 40 + 43 = X
163 = X
Therefore, the total number of flowers grown is 163.

a trader bought some eggs at 64 per dozen and sold 2/3 of them at 240/= per tray and the other 1/3 at 225/= per tray.In so doing she made a profit of 450/=.given 1 tray holds 30 eggs and 1 dozen 12 eggs determine the number of eggs she bought.
Answers
Note that the number of eggs the above-described trader bought is 180 eggs. This is solved using simple arithmetic.
What is the justification for the above response?
Let no. of the eggs be x, then
Money the trader paid for eggs = 64/12x = 16/3x
The money the trader got from
Seling two third eggs =2/3x*240/30
=16/3x
Money get from one third= x/3*225/30
=5/2
Profit= [16/3x+5/2x] - 16/3x
5/2x = 450
x =450*2/5
=180
Therefore, the number of eggs that the trader bought is 180.

D) y=-5/2x; y=-20
Step-by-step explanation:
If y varies directly with x, then y=kx where k is our proportionality constant
Therefore, since y=-5 when x=2, we have -5=k(2) where k=-5/2
This means that when x=8, y=(-5/2)(8)=-20, making choice D correct
How much more would the value of y be on the graph than its value
in the table when x = 12? (1 point)
Answers
Answer:
180
Step-by-step explanation:
From the table :
Slope :
m = (y2 - y1) / (x2 - x1)
m = (100 - 80) / (5 - 4)
m = 20 / 1
m = 20
y = 20x
Hence, when, x = 12
y = 20 * 12
y = 240
From the graph:
Slope :
m = (y2 - y1) / (x2 - x1)
m = (280 - 70) / (8 - 2)
m = 210 / 6
m = 35
y = 35x
When x = 12
Graph :
y = 35 * 12
y = 420
Difference :
420 - 240
= 180

Another estimate you could do is to round everything to 20, since we're close to this value. Having four copies of 20 added leads to 20+20+20+20 = 80
So they rode a total estimated amount of 80 miles

O The margin of error is multiplied by 0.5.
O The margin of error is multiplied by 2.
Answers
Answer:
The margin of error is multiplied by 4.
Step-by-step explanation:
Margin of error is:
[tex]M = \frac{zs}{\sqrt{n}}[/tex]
In which z is related to the confidence level, s is elated to the standard deviation and n is the sample size.
From this, we have that the standard deviation is inversely proportional to the square root of the sample size.
If you cut the sample size in half:
The margin of error is inversely proportional to the square root of the sample size, so if you cut the sample size by [tex]\frac{1}{2}[/tex], the margin of error will be multiplied by [tex]2^2 = 4[/tex]
So
The margin of error is multiplied by 4.

The length of a rectangular lot is 6 feet less than 3 times its
width. Its area is 222 square feet.
Its width is
feet and its length is
feet.
Answers
Answer:
Its width is 9.66 feet and length is 22.98 feet.
Step-by-step explanation:
Let l is length and b is width of a rectangular lot.
Length, l = (3b-6) feet
The area of the lot is 222 sq feet.
The area of a rectangle is given by :
[tex]A=lb\\\\222=(3b-6)b\\\\222=3b^2-6b[/tex]
It is a quadratic equation. The solution of the above equation is given by :
b = 9.66 feet and -7.66 feet
Neglecting negative answer, the width of the lot is 9.66 feet.
Length, l = (3(9.66)-6) = 22.98 feet
Hence, its width is 9.66 feet and length is 22.98 feet.
