$3
its like a pack of 12 magazines costing $36 and you asked the cost of one magazine
by proportion; let average be=?
12~$36
1~?
1/12=?/36
?=(1/12)*36
?=3=average
Answer:
See below
Step-by-step explanation:
15)
In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is
.



The angle
of the other triangle plus the angle
of the right-angle triangle is equal to 90º, therefore they are complementary angles.
So,



To find ?, we have



16)
The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have




Step-by-step explanation:
A vector is defined as an object which has got some value or magnitude and has a direction as well.
The vector =(0,0) is called the zero vector because it has zero length and no direction at all. The zero vector has an undefined direction.
The zero vector behaves same as the number zero and when added to any vector say "a", we get the answer as vector "a" which remains unchanged.
Answer:
4.31
Step-by-step explanation:
Find the cube root of both sides of the equation.
= 
The cube root will cancel out the cubed in the variable.
v = 
Find the cube root of 80. I rounded to the nearest hundredth.
v = 4.31
