Answer:
x = 14
Step-by-step explanation:
For complementary angles, the sum of two angles is equal to 90 degrees.
We have,
ATQ,
Taking like terms together,
4x+x =90-30+10
5x = 70
x = 14
So, the value of x is 14.
The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a x 2c x
3d. Note that 5, 2 and 3 are coefficients and a, c and d, are variables. Multiply first
the coefficients 5, 2 and 3 and you get 30. Always remember that in multiplying
numbers, especially variables, the base of the exponent must be equal. However,
you have variables of a, c and, d. You cannot multiply or add them because they
are different. So the answer is 30acd.
The monthly salary is 2730.00.
Since there are 12 months in a year, to find the annual salary, we multiply the monthly salary by 12 as follows:
Annual Salary = Monthly Salary x 12 = 2730.00 x 12 = 32760.00
Answer:
A.
Step-by-step explanation:
Volume of a cone = ⅓πr²h
Where,
r = x
h = 2x
Plug in the values into the formula for volume
Volume = ⅓*π*x²*2x
Volume = ⅓*π*2x³
Volume = (1*π*2x³)/3
Volume =
