Answer:
20
Step-by-step explanation:
7 times 4 equals 28 and 5 times 4 equals 20 so the answer is 20
<em>Answer</em>
D) 1
<em>Explanation</em>
A perpendicular line makes a angle of 90° with a line or a plane.
If a line is to be drawn from a point to a line or a plain it can only be one. In this case a line is to be drawn through a point A to a plane P. If the line is to be perpendicular, then is is only one.
From the choices, the appropriate answer is D) 1
Dividing the number of tires that should be installed per day which is 400 by the number of working hours which is 8 will give us 50 tires per hour. Assuming that the same mistake will take toll on the workers such that they will have 1 tire mistakenly installed in an hour, they will have 8 erroneous tires in a day. Multiplying this by 5 to make the answer per week will give 40. Out of the 400 x 5 = 2000 tires. The answer would be 2000 - 40 which is equal to 1940. The assumption must be valid.

Answer:
Step-by-step explanation:
<u>Ratio of turns</u>
<u>If A = 60 then the ratio is</u>
- 60/B = 2/3 ⇒ B = 60*3/2 = 90
