The shorter side of a triangle ABC is half of the second side and a third of the longest side how does the perimeter of the triangle compared to the longest side

Answers

Answer 1
Answer: In such questions we mustuse examples.....
Let's imagine that the shortest size is 1
So as it is half of the second the second must be2
As it is the third of the longest size it must be 3

To find the perimeter we must add the three sides.
1+2+3=6
Therefore the perimeter is the double of the longest size
or
The longest size is half of the perimeter

We must take one or two more examples to be sure...
I will take another one

Let's imagine that the shortest size is 5
So as it is half of the second the second must be10
As it is the third of the longest size it must be 15

To find the perimeter we must add the three sides.
5+10+15=30
Therefore the perimeter is the double of the longest size
or
The longest size is half of the perimeter



I wish I helped you ;)

Answers

switch the -3 on the other side of = and reduce and simply.

so it would be 8x=7
                       x=7/8
10x-3-2x=4
(Collect like terms)
8x-3=4
(Get x by itself, subtracf 3 from each side)
8x=1
(Divide 1 by 8)
X = 0.125

Elmer has a collection of 300 fossils. Of those, 21% are fossilized snail shells. How many fossilized snail shells does Elmer have?

Answers

use the percent proportion

 21          x
——  = —— 
100        300

to solve :
21 x 300 = 6300
6300 ÷ 100 = 63

Answer = 63 of Elmer’s shells are fossilized snail shells :)

The midpoint of AB is M (2,0). If the coordinates of A are (7, -2), whatare the coordinates of B?

Answers

Answer:

The coordinates of point B are (-3,2)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

M((x_1+x_2)/(2),(y_1+y_2)/(2))

we have

M(2,0)\n(x_1,y_1)=(7,-2)

substitute

(2,0)=((7+x_2)/(2),(-2+y_2)/(2))

Find the value of x_2

we have that

2=(7+x2)/(2)

4=7+x_2\nx_2=-3

Find the value of y_2

we have that

0=(-2+y_2)/(2)

0=-2+y_2\ny_2=2

therefore

The coordinates of point B are (-3,2)
