-Postcards = P
-large envelope = E
14p + 5e = 12 or 5e = 12 -14 p
10p + 15e = 24.8
5e = 12 - 14 p multiply by 3
15e = 36- 42 p
Combine 10p + 15e = 24.8 and 15e = 36- 42 p
That equals 10p + 36 - 42p = 24.8
10p + 36 - 42p = 24.8
11.2 = 32 p
P = 0.35
Bring down the equation 5e = 12 - 14p and substitute
5e = 12 - 14p
5e = 12 - (14 x 0.35)
5e = 12 - 4.90
5e = 7.10
e = 1.42

What is rectangle?"A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees, opposite sides are parallel and adjacent sides are perpendicular.
For the given situation,
Consider the rectangle ABCD,
The slope of [tex]AB=\frac{1}{2}[/tex]
The slope of parallel sides are equal. Here AB and CD are parallel sides.
So, slope of [tex]AB=CD[/tex].
Hence we can conclude that the slope of CD = 1/2. So, option (3) is correct.

A rope is dropped from the helicopter and it is perpendicular to the ground. What is the distance between Jeremiah and the rope?
Answers
Answer:
About 3000 feet
Step-by-step explanation:
This is a 30,60 90 triangle, all the angles in a triangle adds up to 180.
Use sin ratio
sin 60 = [tex]\frac{o}{4000}[/tex] o for opposite side of triangle from the 60 degree angle
o = 4000 (sin 60) = 3464.11
Use cosine
cos 30 = [tex]\frac{a}{3464.11}[/tex] a for adjacent side of triangle from the 30 degree angle
3464.11 (cos 30) = 3000.01
What is the lateral area of the regular pyramid if the area of the square base is 36 square cm and the slant height is 12 cm? options: 168 144 72 298
Answers
Step-by-step explanation:
Given that,
The area of the square base, A = 36 cm²
Slant height, s = 12 cm
We need to find the lateral area of the regular pyramid. The formula is :
[tex]S=A+\dfrac{1}{2}p\times s[/tex]
Where
A is the area of base
p is perimeter of base
s is slant height
Area of square, A = side²
So,
[tex]side=6\ cm[/tex]
Put values in the above formula.
[tex]S=36+\dfrac{1}{2}\times 4\times 6\times 12\\\\=36+144\\\\=180[/tex]
So, the lateral area of the regular pyramid is equal to 180 cm².
