There is an increase in total participants.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
number of boys = 28
Number of girls = 16
Total participants = 28 + 16 = 44
Now, there is decrease in number of boys by 8%
= 28- 8% x 28
=28- 8/100 x 28
=28 - 0.08*28
=28 -2.24
= 25.76
and, there is 19% increase in number of girls
=16 + 0.19 x 16
=16 + 3.04
=19.04
So, total participants = 25.76 + 19.04
= 44.8
Hence, there is an increase in total participants.

solve for y: ax+by=c
Answer:
y=c-ax/b
Step-by-step explanation:
Subtract ax from both sides.
by=c−ax
Divide both sides by b
by/b=c-ax/b
Dividing by b undoes the multiplication by b.
y=c-ax/b
Answer: y=c-ax/b
Step-by-step explanation:
Subtract ax from both sides.
by=c−ax
Divide both sides by b
by/b=c-ax/b
Dividing by b undoes the multiplication by b.
y=c-ax/b

What is the length of the third side of the window frame below?
A. 10 inches
B. 12 units
C. 16 units
D. 20 units
Answer:
20 units
Step-by-step explanation:
a^(2)+b^(2)=c^(2)
48^(2)+b^(2)=52^(2)
2304+b^(2)=2704
2304-2304+b^(2)=2704-2304
b^(2)=400
\sqrt(b^(2))=\sqrt(400)
b=20
therefore,20 is the length of the unknown side

Answer:
45 words per minute
Step-by-step explanation:
60 / 1 [tex]\frac{1}{3}[/tex]
45
The average typing speed of Joseph in words per minute is 45 words per minute.
What is an average speed?The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.
Now it is given that,
Number of words = typed 60 words
Time taken = 1 and 1/3 minutes
⇒ Time taken = 4/3 minutes
Thus, Average typing speed = Number of words / Time taken
⇒ Average typing speed = 60 / (4/3) words per minute
⇒ Average typing speed = 45 words per minute
Thus, the average typing speed of Joseph in words per minute is 45 words per minute.
