Julia has read her favorite book 6 times,This is 3 times more than her Kami.How many times has Kami read the book?

motikmotik

Answer: The answer is: " 2 " .

_______________________________________________

→ Kami has read the book " 2 (two) " times.

_______________________________________________

Step-by-step explanation:

_______________________________________________

Let "J" represent the number of times julia has read the book.

Let "K" represent the number of times Kami has read the book.

J = 6 ;

J = 3K ;

Solve for "K" ;

J = 6 = 3K ;

→ 6 = 3K ;

↔ 3K = 6 ;

Divide each side of the equation by "3" ;

to isolate "K" on one side of the equation; & to solve for "K" :

→ 3K / 3 = 6 / 3 ;

to get:

K = 2 .

_______________________________________________

The answer is: " 2 " .

→ Kami has read the book " 2 (two) " times.

Simplify ( 1/2A + 1/2B )^2

zysi [14]

Notice that both A and B are multiplied by (1/2).

Thus, the given expression can be re-written as [(1/2)(A+B)]^2.

Square the (1/2) and the (A+B) separately, and then multiply together the resulting squares:

(1/4)(A^2 + 2AB + B^2)

Find the surface area of this triangular prism.

vesna_86 [32]

Answer:

Step-by-step explanation:

A=Area

Using the formulas

$A= 2A_{b} +(a+b+c)h\\A_{b} = \sqrt{s(s-8)(s-10)(s-6)} \\s= \frac{8+10+6}{2}$

Solving for A

$A=ah+bh+ch+\frac{1}{2}*\sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4}$

$A=8(2)+10(2)+6(2)+\frac{1}{2}*\sqrt{-8^{4} +2*(8*10)^{2} +2*(8*6)^{2}-10^{4} +2*(10*6)^{2}-6^{4} }$ $A=96$

Find the distance between each set of points. Round to the nearest tenth, when necessary. (-3, 2) and (1, -6)

vovangra [49]

Answer:

<h2>The answer is 8.9 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3, 2) and (1, -6)

The distance between them is

$d = \sqrt{ ({ - 3 - 1})^{2} + ({2 + 6})^{2} } \\ = \sqrt{ ({ - 4})^{2} + {8}^{2} } \\ = \sqrt{16 + 64} \\ = \sqrt{80} \: \: \: \: \: \: \: \: \: \: \\ = 4 \sqrt{5} \: \: \: \: \: \: \: \: \: \: \\ = 8.9442719...$

We have the final answer as

8.9 units to the nearest tenth

Hope this helps you
