monthly salary of a teacher was Rs 12000 last month.lf the salary increase by 20% find his salary this month
Answer:
new salary = ₹ 14400
Step-by-step explanation:
here's your solution
==> monthly salary = ₹ 12000
==> percentage increase in salary = 20%
=> we need to find 20% of 12000
==> increased amount = ₹ 2400
==> salary of this month = 12000 + 2400
==> new salary = ₹ 14400

HELP PLEASE. find the volume of the figure. (3.14 as pi)
Answer:
The volume of the figure is 720 cm^3
Step-by-step explanation:
Here, we want to find the volume of the figure
mathematically, we can have this as the product of the base of the figure and it’s height
the base is a rectangle and the area is the product of the side lengths
Mathematically, we have this as;
9 * 20 = 180 cm^2
So the volume here can be obtained by simply multiplying by the height of the shape
we have this as;
180 cm^2 * 4 cm = 720 cm^3
PLEASE HELP ASAP

Find the volume of the sphere. Round your answer to the nearest tenth.
Answer:
See below.
Step-by-step explanation:
The formula for the volume of a sphere
= 4/3 π r^3 where r = the radius.
So for number 1:
V = 4/3 π (5)^3
= 523 .60 mm^3 to nearest hundredth.
The others are solved in exactly the same way except where the diameter is given as in number 4 and 5 you get the radius r by dividing the diameter by 2. So in number 4, r = 30/2 = 15.
A sphere has a volume of V = 1764 in. Find its surface area.
Answer:
The surface area is 706.02
Step-by-step explanation:
SA = 224.4pi (704.62)
Alternatively (706.02 without rounding)
First, we need to find the radius of the sphere with the following equation
[tex]r = (3\frac{V}{4\pi } )^\frac{1}{3} \\r = (3\frac{1764}{12.56} )^\frac{1}{3} \\r = (3*140.45)^\frac{1}{3} \\r = (421.35)^\frac{1}{3} \\r = 7.49[/tex](pi as 3.14)
Now we can find the surface area using the following equation
[tex]SA = 4r^2\pi \\SA = 4(56.1)\pi \\SA = 224.4\pi \\[/tex]

The ages in years of eight boys are 14,
14.5, 12, 11.5, 15, 13, 10.5, 13.5. What is
their average age?
A. 14 B. 13
C. 12 D. 11
Answer:
B) 13
Step-by-step explanation:
Average age means to calculate mean:
Mean = (Sum of all numbers)/(Number of numbers)
Mean = (14 + 14.5 + 12 + 11.5 + 15 + 13 + 10.5 + 13.5)/8
Mean = (104)/8
Mean = 13

4x – 4 = – 12
X = ?
What is X ?
Answer:
X=-2
Step-by-step explanation:
4x-4=-12
Add 4 on both sides
+4 +4
4x=-8
Divide by 4 on both sides
÷4 ÷4
X=-2
Answer:
-2
Step-by-step explanation:
4x-4=-12
4x=-12+4
4x=-8
x=-8/4
x=-2
solve 6x + 6 = 3x - 6
Answer:
x = -4
I hope it's helps you t
Answer:
x = -4
Step-by-step explanation:
Simplifying
6x + 6 = 3x + -6
Reorder the terms:
6 + 6x = 3x + -6
Reorder the terms:
6 + 6x = -6 + 3x
Solving
6 + 6x = -6 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
6 + 6x + -3x = -6 + 3x + -3x
Combine like terms: 6x + -3x = 3x
6 + 3x = -6 + 3x + -3x
Combine like terms: 3x + -3x = 0
6 + 3x = -6 + 0
6 + 3x = -6
Add '-6' to each side of the equation.
6 + -6 + 3x = -6 + -6
Combine like terms: 6 + -6 = 0
0 + 3x = -6 + -6
3x = -6 + -6
Combine like terms: -6 + -6 = -12
3x = -12
Divide each side by '3'.
x = -4

Find the area of this parallelogram. Be sure to include the correct unit in your answer.
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
Answer:
A = 126 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 14 and h = 9 , then
A = 14 × 9 = 126 cm²
