Mel has a net annual income of $53 246 after 21% of her income is C withdrawn for tax purposes. What was her gross income?
Answer:
$67400
Step-by-step explanation:
Given that :
Net income = 53246
Deduction (tax purposes) % = 21%
Gross income = net income + deduction
Let gross income = x
x = 53246 + 21% of x
x = 53246 + 0.21x
x - 0.21x = 53246
0.79x = 53246
x = 53246 / 0.79
x = 67400

Area of a square is 196 cm²
. Find the perimeter of the square. (ii) If the square is altered into a rectangle by increasing the length by x
centimeters, and decreasing the breadth by y centimeters, find the area of
the rectangle in terms of x and y.
Step-by-step explanation:
Area of Square=side²
Side=√(Area of the square)
Given area of the square=196cm²
Side of the square=√196=14cm
Perimeter of square=4*side=4*14=56cm
Length of the rectangle=(14+x)cm
Breadth of the rectangle=(14-y)cm
Area of rectangle=Length*Breadth=
(14+x)(14-y)=14(14)+14(-y)+x(14)+x(-y)=(196-14y+14x-xy)cm²

keith buys 6 pencils for 90p
how much does one pencil cost?
how much would five pencils cost
how much would eleven cost ?
Answer:
1 Pencil = 15p
5 Pencils = 75p
11 Pencils = 165p --> £1.65
Step-by-step explanation:
To find one pencil... 90 / 6 = 15
To find 5 pencils... 15 (worth 1 pencil) * 5 = 75
To find 11 pencils... 15 (worth 1 pencil) * 11 = 165 which is £1.65

determine an equation and the radius for the circle that has its centre at the origin (0,0) passes through the point A 4-3
Given:
The center of the circle is at (0,0).
The circle passes through the point A(4,-3).
To find:
The radius and the equation of the circle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The radius of the circle is the distance between the points (0,0) and (4,-3).
[tex]r=\sqrt{(4-0)^2+(-3-0)^2}[/tex]
[tex]r=\sqrt{(4)^2+(-3)^2}[/tex]
[tex]r=\sqrt{16+9}[/tex]
[tex]r=\sqrt{25}[/tex]
[tex]r=5[/tex]
So, the radius of the circle is 5 units.
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is center of circle and r is the radius.
Putting h=0, k=0, r=5, we get
[tex](x-0)^2+(y-0)^2=5^2[/tex]
[tex]x^2+y^2=25[/tex]
Therefore, the radius of the circle is 5 units and the equation of the circle is [tex]x^2+y^2=25[/tex].
