Answer:
sin(-)=perpendicular/hypotenuse
Sin(-)=AB/BC
Because AB is the perpendicular with reference to angle (-) and BC the hypotenuse since the right angle is facing towards it.Then,
Sin(-)=4/5
Answer:
a) cluster sampling
Step-by-step explanation:
In cluster sampling method, each member of a population is assigned to one and only one group.This means clusters are formed through probability method usually a simple random sampling.The participants in the clusters are the only one to be surveyed.
In this example, simple random sampling is used to identify 12 home rooms(cluster) where a group of 20 students (participants) in each room is given the survey.
Answer:
Matt will need 10176 square quilts to cover the wall
Step-by-step explanation:
To answer this perfectly, we will have to first convert everything to the same unit.
dimensions of the quilt squares = 3 inches
Length of the wall = 1 yard = 36 inches
Breadth of the wall = 212 feet = 2544 inches.
The next step, is to find the area of the wall that Matt is covering.
Area of wall = length X breadth = 36 X 2544 = 
We will also find the area of the square quilts. This is given as length X length = 
=
to get the number of square quilts that will cover that area, we will have to divide the area of the wall by the area of the quilts
= 91584 /9 = 10176 quilts
Matt will need 10176 quilts to cover the wall
Area= (length)(width)
divide by (length) on both sides.
(width)= (area)/(length).
Your best bet is treating area, length, and width as numbers. You can plug in numbers and take them out in the end. Hope this helps!
Based on the number of pages read and the time it was read in, the number of pages read per day was <u>44 pages. </u>
Marion read 616 pages and did this in 14 days.
She read the same number of pages each day so the number of pages read per day was:
<em>= Number of pages read in total / Number of days </em>
= 616 / 14
= 44 pages
In conclusion, she read 44 pages per day.
