The mass of brick is 2478 gram.

<h3>What is a rectangular prism?</h3>

A rectangular prism has a total of 6 faces, 12 sides, and eight vertices. Like a cuboid, it has three dimensions- the base width, the height, and the length. The top and base of the rectangular prism are rectangular in shape. The pairs of opposite faces of a rectangular prism are identical or congruent.

A brick is in the shape of a rectangular prism with a length of 8 inches, a width of 3.5 inches, and a height of 2 inches.

The volume of rectangular prism = length×width×height

                                                        = 8×3.5×2

                                                        = 56

Thus volume of brick is 56 cubic inches.

Convert inches to centimeter

1 inch = 2.54 centimeter

Therefore,

56 cubic inches = 56 x 2.54 x 2.54 x 2.54 cubic centimeter

56 cubic inches = 917.676 cubic centimeter

Thus, we get,

volume of a rectangular prism = 917.676 cubic centimeter

The brick has a density of 2.7 grams per cubic centimeter

Density = 2.7 grams

The mass of brick is given by formula = density × volume

\Rightarrow                                                            = 2.7 × 917.676

\Rightarrow                                                            = 2477.72

\Rightarrow                                                            ≅ 2478  

Thus mass of brick is 2478 gram.

Is the perimeter and area of the square always the same?
avanturin [10]
I think it would be because say you have a square and all the sides are 4. If you add all the sides you would get 16 for the perimeter. If you do 4 x 4 you would get 16 as the area. So i think they are the same but i am sometimes stupid so dont just take my word on it.
Hope this helps! :)

a crew of highway workers paved 2/15 mile in 20 minutes.if they continued working at the same rate,what portion of a mile wil th
icang [17]

Answer:

2/5 of a mile

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than  

20 minutes. The longer the time, the more they will pave.


2/5  of a mile, in 20 minutes, how much in 60 minutes?(#)

They will pave 3 times more.

2/15 x 3/1 = 6/15 of a mile

6/15 = 2/5 of a mile

For what value(s) of k will the relation not be a function
skelet666 [1.2K]

We are given two relations

(a)

Relation (R)

R=[((k-8.3+2.4k),-5),(-\frac{3}{4}k,4)]

We know that

any relation can not be function when their inputs are same

so, we can set both x-values equal

and then we can solve for k

k-8.3+2.4k=-\frac{3}{4} k

3.4k-8.3=-\frac{3}{4}k

3.4k\cdot \:10-8.3\cdot \:10=-\frac{3}{4}k\cdot \:10

4k-83=-\frac{15}{2}k

34k=-\frac{15}{2}k+83

\frac{83}{2}k=83

83k=166

k=2............Answer

(b)

S = {(2−|k+1| , 4), (−6, 7)}

We know that

any relation can not be function when their inputs are same

so, we can set both x-values equal

and then we can solve for k

2-|k+1|=-6

2-\left|k+1\right|-2=-6-2

-\left|k+1\right|=-8

\left|k+1\right|=8

Since, this is absolute function

so, we can break it into two parts

|f\left(k\right)|=a\quad \Rightarrow \:f\left(k\right)=-a\quad \mathrm{or}\quad \:f\left(k\right)=a

k+1=-8\quad \quad \mathrm{or}\quad \:\quad \:k+1=8

we get

k+1=-8\quad

k=-9

k+1=8\quad

k=7

so,

k=-9\quad \mathrm{or}\quad \:k=7...............Answer

Naddika [18.5K]

Answer:

Exact form : x = +_2 squareroot 11+5

Decimal form : x=11.63324958...,-1.63324958...

Step-by-step explanation: Use the formula (b/2)^2 in order to create a new term. Solve for x by using the term to complete the square.

I hope this helps you out! :)
