Answer:
10
Step-by-step explanation:
If there is a constant rate of change, its value will be ...
k = y/x
k = 250/25 = 10
The constant rate of change is 10.
y = 10x
Answer:
<h3>D. The amount of rotation of one side.</h3>
Step-by-step explanation:
We need to explain the statement " What affects the size of an angle? ".
Given options are
A. The length of its sides
B. The direction of one side
C. Its orientation in space
D. The amount of rotation of one side.
The correct option would be :
<h3>D. The amount of rotation of one side.</h3>
<em>Because as the one side rotated, it makes a greater or smaller arc between the two lines. That would affects the size of an angle. </em>
The angle TQS is 74° and the angle SQR is 106°
Answer:
1) a right triangle
Step-by-step explanation:
One of the caractheristics of a right triangle, the one in which the sum of the two sides squared is the hypotenuse squared(Pytagorean Theorem), is also the the altitudes of a triangle meet at one of the triangle’s vertices. So 1) is the answer to this question.
Step-by-step answer:
Answer to problems of this kind is the reciprocal of the harmonic mean of the time required.
We need to find the average of the speeds, not the average of the time.
The respective speeds are 1/3 and 1/4.
The average of the speeds is therefore (1/3+1/4)/2 = 7/24 (harmonic mean of the time taken).
The time required is therefore the reciprocal of the unit speed,
T = 1/(7/24) = 24/7 = 3 3/7 minutes, or approximately 3.43 minutes.
