Cupid bought some valentines for $2.50. How much did he pay in sales tax if the tax rate is 6.5%?

Answers

       item cost = $2.50

sales tax rate = 6.5% --------------> 0.065
                                           
                      = $2.50 × 0.065 
                      ≈ 0.16
                      = $2.50 + 0.16
                      = $2.66
                    

So Cupid paid $2.66.

A sphere has a diameter of 12 ft. what is the volume of the sphere? give the exact value in terms of .

Answers

Formula of volume of a Sphere is : V = 4/3 πr³

Here, Diameter (2r) = 12, so radius (r) = 12/2 = 6 feet
Substitute it into the formula,
V = 4/3 π(6)³
V = 4/3 *216π
V = 288π Ft² [ Answer in the term of π ]

You can also solve it for numeral value by substituting the value of π = 22/7
V = 288 * 22/7 = 905.15 Ft² [ Answer in numbers ]

Hope this helps!


The volume of the sphere is 905.15 square feet.

Given

A sphere has a diameter of 12 feet.

What is the volume of the sphere?

The volume here depends on the diameter of the radius of the sphere since if we take the cross-section of the sphere, it is a sphere.

The surfacearea of the sphere is the area or region of its outer surface.

The volume of the sphere is calculated by the following formula;

\rm Volume \ of \ sphere = (4)/(3)\pi r^3

Where r is the radius of the sphere.

The radius of the sphere is given by;

\rm Radius = (Diameter)/(2)\n\nRadius = (12)/(2)\n\nRadius = 6 \ feet

Therefore,

The volume of the sphere is;

\rm Volume \ of \ sphere = (4)/(3)\pi r^3\n\n\rm Volume \ of \ sphere = (4)/(3) * 3.14 * (6)^3\n\n\rm Volume \ of \ sphere = (4)/(3) * 3.14 * 216\n\n\rm Volume \ of \ sphere = 905.15 \ feet^2

Hence, the volume of the sphere is 905.15 square feet.

Evaluate the following expression: (7+5b)+1 , if b = 3

Answers

The value of the expression will be 23.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the expression is (7+5b)+1. Then the value of the expression at b = 3 will be:-

E = 7+5b)+1

E = 7 + ( 5 x 3 ) + 1

E = 7 + 15 + 1

E = 23

Therefore, the value of the expression will be 23.

Bob is 15 and susan is 21, find the ratio of his age to hers____________

Answers

Ratios can be expressed with a colon, fraction bar, or the word 'to' inbetween.

Bob's age:Susan's age
Bob's age/Susan's age
Bob's age to Susan's age

Of course we can substitute their ages here to get our ratio.

15:21, 15/21, or 15 to 21.

Just like a fraction, it can be simplified.
If you multiply/divide the top and bottom by the same number the ratio stays the same, just like how 1/2 = 2/4 = 3/6.

15 and 21 are both divisible by 3, so our ratio 15:21 can simplify to 5:7.
so ratio of bob to susan=bob:susan
bob=15
susan=21
bob:susan=15:21
these are like fractions or equal signs so
15:21=5:7

ratio is 5:7
