Answer: 81
Step-by-step explanation:
Mean of four nos = 85
Score = 85 x 4 = 340
Deduct 97 from 340 = 243
Mean of three nos. 243/3 = 81
Answer:
The correct answer is option D. 5.7 units
Step-by-step explanation:
It is given a square, Its diagonals meet to form four right angles
<u>To find the value of x</u>
From the figure we can see that the triangle with sides x, x, 8 have angles 45°,45° and 90°
If the angles are 45°,45° and 90° then sides are in the ratio 1 : 1 : √2
Here x : x : 8 = 1 : 1 : √2
Therefore x = 8√2 = 8/1.414 = 5.6577 ≈ 5.7 units
Therefore the correct answer is option D 5.7 units
I’m pretty sure the answer is 10
Answer:
C) Similar but not congruent
Step-by-step explanation:
These figures are similar not congruent because:
In order for a triangle to be congruent it has to be the same size and shape.
There is no such thing as congruent but not similar as if it's congruent it is similar.
However, in order for a triangle to be similar it must have the same shape( angles).
So we can see that both triangles are isoceles and the sides of each are in a ratio of 2:1. Meaning that the bigger triangle has sides that are exactly twice as large as the smaller trinage. This also means that the angles are equal. Hence they are similar but not congruent.
Answer:
5
Step-by-step explanation:
I played a video game for 15 minutes and I lose 75 points.
So, at time = 0, point loss =0, and at time = 15 minutes, point loss = 75.
Therefore, the mean change in points per minute is = ( total loss of points / total minutes of playing the game )
= 
= 5 points per minute.
Hence, the integer 5 represents the mean change in points per minute. (Answer)
