Step 1) Find common denominator. In this case it was 28.
Step 2) Multiply 1/4 by seven to get 7/28 and then 2/7 by 4 to get 14/28.
Step 3) Add numerators: 7+14 to get 21
Step 4) Simpify your new added Fraction 21/28= 3/4
Your answer is 3/4

Answer:
The height of the taller building is: 51.345m
Step-by-step explanation:
Given
The question has missing details (See attachment for the illustration of the complete question)
Required
The height of the tall building
The height, a, is calculated as:
To solve for b, we consider the upper half of the attached image
The upper half is a right triangle.
Using tan formula, we have:
Solve for b
To solve for c, we consider the lower half of the attached image
Using tan formula, we have:
Solve for c
Recall that:
So:
Answer:
He can have 8 cards in each pile amounting at a total of 15 piles of cards.
<span>Amount of
emails which are sent = 12,000
Amount of emails which are opened = 300
the question asked the open rate as a percentage. </span>
<span>Hence, we can write
open rate as,
Open rate = (number of opened emails / number
of sent emails) x 100%
= (300 / 12,000) x
100%
= 2.5 %</span>

I'm guessing, but did you mean to ask about a regular POLYGON?
Each exterior angle of a regular POLYGON =360 degrees / (number of sides)
So for a triangle 360 / 3 = 120
a square 360 / 4 = 90
a pentagon 360 / 5 = 72
a hexagon 360 / 6 = 60
and so on.
