Answer:
The improve in speed is 3.9334 words/min
Step-by-step explanation:
we will find speed at both occasions and then we can subtract them
First test:
total number of word =694
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
Second test:
total number of word =753
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
So, improve in speed is


word/min
Answer:
A. 20t² + 9t - 20
Step-by-step explanation:
(5t × 4t) + (5t × 5) - (4 × 4t) - (4 × 5)
= 20t² + (25t - 16t) - 20
= <u>20t² + 9t - 20</u> (A)

Simplify the following:
(y^6 y^8)/((2 x^2)/(x^4))
Combine powers. (y^6 y^8)/((x^2×2)/x^4) = (y^(8 + 6) x^(4 - 2))/2:
(y^(8 + 6) x^(4 - 2))/2
8 + 6 = 14:
(y^14 x^(4 - 2))/2
4 - 2 = 2:
Answer: (y^14 x^2)/2
Answer:
largest angle = 92°
Step-by-step explanation:
Since the measurement of the angles are;
x°, ( x + 6)°, (2x + 10)°
And we know that sum of angles in a triangle is 180. Thus;
x + (x + 6) + (2x + 10) = 180
x + x + 6 + 2x + 10 = 180
4x + 16 = 180
4x = 180 - 16
4x = 164
x = 164/4
x = 41°
The other two angles will be;
(41 + 6)° and (2(41) + 10)°
Which gives;
47° and 92°
So,largest angle = 92°
