How can -6.75 + (10.25) be expressed as the sum of its integer and decimal parts
ArbitrLikvidat [17]

Answer:

 -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Here, the integer part  =     ( (-6)  + (10))

Decimal part =   ( (-0.75) + (0.25))

Step-by-step explanation:

Here, the given expression is:    -6.75 + (10.25)

Now, -6.75  = (-6)  +  (-0.75)

Also, (10.25)  = (10)  + (0.25)

So, the expression can be written as

 -6.75 + (10.25)  =  (-6)  +  (-0.75) +  (10)  + (0.25)

                           = ( (-6)  + (10))  + ( (-0.75) + (0.25))

or,   -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Where the integer part is    ( (-6)  + (10))

and the decimal part is  ( (-0.75) + (0.25))

Find the sum of the first 48 terms of the following series, to the nearest integer.
Andru [333]

Answer:

3,672

Step-by-step explanation:

Given the sequence 6, 9, 12...

The sequence is an arithmetic sequence

first term a = 6

common difference d = 9 - 6 = 12 - 9 = 3

number of terms n = 48

Sn = n/2[2a+(n-1)d]

Substitute the given values

S48 = 48/2[2(6)+(48-1)(3)]

S48 = 24(12+(3*47))

S48 = 24(12+141)

S48 = 24(153)

S48 = 3,672

Hence the sum of the first 48terms is 3,672

A cone has a diamete of 3 inches the cone hold 12 cubic inches of water to the nearet inch what is the height of the cone
Andre45 [30]

Volume for a cone is 1/3 pi * r^2*h, where r is radius and h is height. We have diameter = 1/2 radius. Thus, radius = 1.5in. We also have volume is 12 in. Using formula for volume of a cone and plugging in what we know, we have 12 = 1/3*pi*(1.5)^2*h, were solving for h. To get, h= (12*3)/(pi*(1.5)^2), which is approximately 5.0931in, 5 inches

The Kuroshio Sea tank is 27m long, 35m wide and 10m deep. What is the volume of the tank? Show your
umka21 [38]

The volume of Kuroshio Sea rank is 9450 cubic meters, if the sea tank is  27m long, 35m wide and 10m deep.

Step-by-step explanation:

The given is,

                 Kuroshio Sea tank is 27m long, 35m wide and 10m deep.

Step:1

                Sea tank looks like a rectangular prism,

                 Formula to calculate the volume of rectangular prism,

                                   Volume, V =whl.............................(1)

                Where, w - Width of the rectangular prism

                              h - Height or depth of the rectangular prism

                               l - Length of the rectangular prism

              From given,

                       w = 35 meters

                         l = 27 meters

                        h = 10 meters

             Equation (1) becomes,

                                              V = (35)(10)(27)

                                                  = (945)(10)

                                                 =9450

      Volume of the sea tank, V = 9450 Cubic meters

Result:

         The volume of Kuroshio Sea rank is 9450 cubic meters, if the sea tank is  27m long, 35m wide and 10m deep.
