the sides of a triangle have lengths s,s+4,and 3s write an expression that represents the perimeter of the triangle

1 answer:

3 0

Perimeter of a poligon= sum of all sides.
Perimeter of this triangle=s+(s+4)+3s=5s+4

An expression that represents the perimeter of this triangle is: 5s+4

Well well we find the area of the triangle first:
area = 1/2 * base * height
area = 1/2 * 8 1/4 * 5 3/4
area = 1/2 * 33/4 * 23/4
area = 1/2 * 759/16
area = 759 / 32
area = 23 23/32

now if we multiply the length of the triangles we get volume because the volume of the prism is really just the sum of the areas of all the triangles that make up it's length. So:
volume = 23 23/32 * 12
volume = 276 276/32
276/ 32 = 8 5/8
volume = 284 5/8

Jenny purchased a prepaid phone card for $30 . long distance calls cost 6 cents a minute using this card. jenny used her card on

yuradex [85]

So if she still has $27.12, then during her call, she used a total of $2.88.

$2.88 = 288 cents.

Therefore 288 divided by 6 = 48

Therefore the answer is 48 minutes.

Plz help me this question plz plz help plz help me all four of them plzzzz

garik1379 [7]

Answer:

10) The equation of a line parallel to $y=-3$ passing through the coordinate (2,6) is $y=6$

11) The equation of a line perpendicular to $y=-3$ passing through the coordinate (2,6) is $x=6$

12) The equation of a line parallel to $x=4$ passing through the coordinate (-2,3) is $x=-2$

13) The equation of a line perpendicular to $x=4$ passing through the coordinate (-2,3) is $y=3$

Step-by-step explanation:

For any line parallel to X-axis the equation we have

$y=a$

where a is the y coordinate.

∴ The equation of a line parallel to $y=-3$ passing through the coordinate (2,6) is $y=6$

For any line parallel to Y-axis the equation we have

$x=b$

Where b is the x coordinate.

∴ The equation of a line parallel to $x=4$ passing through the coordinate (-2,3) is $x=-2$

For any line perpendicular to X-axis is parallel to Y axis therefore the equation we have

$x=b$

∴ The equation of a line perpendicular to $y=-3$ passing through the coordinate (2,6) is $x=6$

For any line perpendicular to Y-axis is parallel to X axis therefore the equation we have

$y=a$

∴ The equation of a line perpendicular to $x=4$ passing through the coordinate (-2,3) is $y=3$
