Answer:

The correct number of basic operations that exist in mathematics is four (addition, subtraction, multiplication and division) because the definition of an operation is the carrying out of a task by the application of principles and these four operation are arithmetic operations that have precedence rules or order of operations, such that we must first multiply or divide before adding or subtracting

Division is different from simply multiplying by a fraction because in Euclidean division, the result is a quotient and a remainder, which shows that division can yield more than one result while multiplication yields a single result

For subtraction and addition, one of the differences is that subtraction cannot be simply commuted

a - b = -(b - a)

Subtraction is non-associative;

a - b - c when arranged as (a - b) - c and a - (b - c), can yield different results depending on operation order which is unlike addition

Therefore, the four basic operations in mathematics are addition, subtraction, multiplication and division

Which of the following choices

Lapatulllka [165]

Answer:

Denote AH as height of triangle ABC, with H lies on BC.

Applying sine theorem:

AH/AC = sin 60

=> AH = AC x sin 60 = 47 x sqrt(3)/2 = 40.7

=> Area of triangle ABC is calculated by:

A = AH x BC x (1/2) = 40.7 x 30 x (1/2) = 610.5 = ~611

=> Option C is correct.

Hope this helps!

Answer:

B) $747.7 \ yd^2$

Step-by-step explanation:

Given:

Height of cylinder (h) = 10 yd

Diameter of cylinder (d) = 14 yd

We need to find the surface area of the cylinder.

Solution:

First we will find the radius of the cylinder.

Radius is half of the diameter.

radius (r) = $\frac{14}{2} = 7\ yd$

Now we know that;

Surface area of cylinder is equal to 2 times π times radius(r) times sum of radius (r) and height (h).

Framing in equation form we get;

Surface area of cylinder = $2\pi r(h+r)$

Substituting the given values we get;

Surface area of cylinder = $2\pi \times 7(7+10)= 2\pi \times7\times 17 = 747.699 \yd^2$

Rounding to nearest tenth we get;

Surface area of cylinder = $747.7 \ yd^2$

Hence the surface Area of cylinder is $747.7 \ yd^2$ .
