Step-by-step explanation:
Answer: 62 words per minute.
Step-by-step explanation: 496/8=62.
#1: 15%
#2: 1/10 = 10%
There are 6 girls who have blonde hair out of 40 students; 6/40 = 15%.
There are 4 boys that have black hair out of 40 students; 4/40 = 1/10 = 10%.

After inserting the given values, u + xy becomes (2) + (9)(6), or 2 + 54, or 56.
Answer: The area is 268 cm squared (approximately)
Step-by-step explanation: The area of a parallelogram is given as ;
Area = b x h
Where b is the base and h is the vertical height. However the vertical height is not given, so we shall apply the trigonometric ratio to determine the vertical height. If we draw a straight line from the the top right vertex down to the base, we would have constructed a right angled triangle with hypotenuse 13cm, and reference angle 79 degrees. We can now calculate the vertical height as follows;
Sin 79 = opposite/hypotenuse
Sin 79 = h/13
By cross multiplication we now have
Sin 79 x 13 = h
0.9816 x 13 = h
12.76 = h
With the vertical height now known, we can calculate the area as follows
Area = b x h
Area = 21 x 12.76
Area = 267.96 cm squared
