find the area of 20mm 14mm 32mm
Answer:
42 is an area
Step-by-step explanation:
The area of a trapezium.
= 1/2 x (a + b) x h
Where a and b are the two parallel sides.
The area of a semicircle.
Area of a circle = πr²
Area of the semicircle = 1/2 x πr²
The area of20mm 14mm 32mm is 521 mm²
What is a circle?
A circle is a two-dimensional figure with a radius and circumference of 2 x pi x r.
The area of a circle is given as:
Area = πr²
We have,
Figure:
The figure is a combination of a trapezium and a semicircle.
The area of a trapezium.
= 1/2 x (a + b) x h
Where a and b are the two parallel sides.
a = 32 mm
b = 20 mm
h = 14mm
= 1/2 x (32 + 20) x 14
= 52 x 7
= 364 mm²
The area of a semicircle.
Area of a circle = πr²
Area of the semicircle = 1/2 x πr²
Diameter = 20 mm
Radius = 20 / 2 = 10 mm
= 1/2 x π x 10²
= 1/2 x 3.14 x 10 x 10
= 3.14 x 10 x 5
= 157 mm²
Now,
The area of the figure.
= area of trapezium + area of semicircle
= 364 + 157
= 521 mm²
Thus,
The area of20mm 14mm 32mm is 521 mm²

If the output and input of a linear equation are proportional, where will the graph of the equation cross the x-axis?
If the output and input of a linear equation are proportional, the graph of the equation cross the x-axis at (0, 0).
What are proportional functions?In any function, the amount of one quantity is dependent on the amount of another. All proportional functions use a rate in the same way. We call the rate the constant of variation, or the constant of proportionality. It’s a constant because this number does not change within the function. Because the input and output are linked by a constant, changes in the independent variable cause the dependent variable to change in a proportional, steady way.
y ∝ x
⇒ y = kx
where k is the constant of proportionality.
For the graph of this function to cross x axis, y = 0
When y = 0 and k is some non zero constant value, x = 0
Thus, the coordinate at which the graph of the function crosses x axis is (0, 0).

What transformations were applied to ABCD to obtain AB'C'D?
A. Rotate 180 degrees counterclockwise about the origin, then
translate 2 units left
B. Rotate 90 degrees counterclockwise about the origin, then
translate 3 units left
C. Rotate 90 degrees counterclockwise about the origin, then
translate 2 units right
D. Rotate 90 degrees counterclockwise about the origin, then
translate 2 units left
Answer: The answer is B
Step-by-step explanation:
The transformation applied to A'B'C'D' is rotating the quadrilateral by 90 degrees counterclockwise about the origin, then translating 3 units left
What is Rotation?The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (-y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)
Given data ,
Let the quadrilateral be represented as ABCD
Now , the transformed quadrilateral is A'B'C'D'
And , coordinates are A ( 1 , 5 ) , B ( 1 , 9 ) , C ( 5 , 9 ) and D ( 5 , 5 )
Now , the square is rotated by 90° counterclockwise and translated 3 units to the left
So , 90° counterclockwise rotation: (x,y) becomes (-y,x)
The coordinates are A' ( -5 - 3 , 1 ) , B' ( -9 - 3 , 1 ) , C' ( -9 - 3 , 5 ) and D' ( -5 - 3 , 5 )
The coordinates are A' ( -8 , 1 ) , B' ( -12 , 1 ) , C' ( -12 , 5 ) and D' ( -8 , 5 )
Hence , the quadrilateral is rotated by 90° counterclockwise and translated 3 units to the left

Questions 7-10: Johnny sister, Jamila, sells chocolate candy bars. Her profit is represented by the function
M(x) = 3x – 20, where M(x) represents the money made after x number of candy bars have been sold.
7. How many candy bars would Jamila have to sell to begin making money (meaning that she makes $1)?
Answer:
the answer is 7 candy bars
Step-by-step explanation:
theres two ways of doing this the equation way and the common sense way m(x) basically just means y so y= 3x -20 we can set y to 0 so 0 = 3x -20 next add 20 to the other side 20 = 3x then divide both sides by 3 you get x= 6.666 but you cant sell .666 of a chocolate bar so round to 7 and thats your answer. the other strategy is saying hey i get $3 per candy bar what number would put be at 21 since 21-20= $1 and we say 7*3 = 21 so 7 is the answer.

You purchase a birthday gift for $105.00. You recall the tag above the gifts to read $175.00 as a retail price. You are pleasantly surprised at the discount that you had not seen. What was the percentage of discount offered on your gift? i assume the answer will be 70%?
We then swap this around for the lower number that equals to 100.
100-60= 40
40%
I hope this is helpful.
Answer:
If the retail price was $175.00, and you purchased this item for $105.00, then the discount was 40%
Step-by-step explanation:
[tex]\frac{105}{175} = \frac{21}{35}= \frac{3}{5} = 0,6[/tex] - that means you paid 60% out of the total price
the discount however is not the percentage that you paid, but the X% OFF, so in that case:
[tex]100 - 60 = 40[/tex]
The discount on this item was 40%

Write the equation of the parabola in vertex form.
vertex (1,3), point (2, - 1)
Answer:
[tex]y=-4x^2+8x-1[/tex]
Step-by-step explanation:
I am assuming the parabola has his axis parallel to the y axis. You should remember from theory that the axis (and thus the first coordinate of the vertex) is [tex]-\frac b{2a}[/tex] and then you have two points of passage.
[tex]-b/2a = 1\\a(1)^2 +b(1)+c =3\\a(2)^2+b(2)+c=-1\\[/tex]
Let's solve subtracting the 3rd from the second and keeping the first as is (ok, slightly rewriting it).
[tex]2a=-b\rightarrow 2a+b =0 \\a+b+c=3\\4a+2b+c=-1\\III-II: 4a+2b+c-a-b-c=-1-3 \rightarrow 3a+b=-4 \rightarrow a +(2a+b)=-4\\a= -4; b=8; c =3 +4 -8 =-1[/tex]

u Estimate the amount of the tip by rounding the bill to the nearest ten dollars before calculating. 20% tip on a bill of $123.42 The amount of the tip is approximately $
Answer:
Tip formula
In general, the tip amount is the cost times 0. xx and your total including tip, is the cost times 1. xx where xx = the percent you want to leave. If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.
