Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If AB is tangent to circle O at point A
then
AB is perpendicular to AO (radius) and Triangle ABO is a right triangle
so
----> by complementary angles in a right triangle
substitute the given value
Answer:
a)
Lowell: 4 counselors
Fairview: 9 counselors
b)
2 new counselors
Step-by-step explanation:
How many counselors should be assigned to each school using Hamilton's method?
Number of students
Lowell: 3584
Fairview: 6816
Total number of students: 10400
Divisor D = (Total number of students)/(number of counselors)= 10400/13 = 800
<u>Temporal assignment</u>
3584/800 = 4 + 0.48 ==> 4 counselors for Lowell
6816/800 = 8 + 0.52 ==> 8 counselors for Fairview
There is one counselor left. According to Hamilton's method she should be assigned to the school with the largest remainder, that is Fairview.
<u>Final assignment</u>
Lowell: 4 counselors
Fairview: 9 counselors
The next year, a new school is opened, with 1824 students. Using the divisor from above, determine how many additional counselors should be hired for the new school
1824/800 = 2 + 0.28
<em>Two new counselors should be hired.</em>
Answer:
8

plz me
It is equivalent to the expression 4x because when you add like terms it becomes 6-6+4x and since 6-6 is 0, only 4x is left.

Answer:
Length of straw = 11 inch (Approx.)
Step-by-step explanation:
Given:
Length of cuboid = 9 inch
Width of cuboid = 5 inch
Height of cuboid = 4 inch
Find;
Length of straw
Computation:
Length of straw = Diagonal of cuboid
Diagonal of cuboid = √l² + b² + h²
Diagonal of cuboid = √9² + 5² + 4²
Diagonal of cuboid = √81 + 25 + 16
Diagonal of cuboid = √122
Diagonal of cuboid = 11.04
Length of straw = 11 inch (Approx.)
