The required simplified value of b + g is 21.
Given that,
At a classroom costume party, the average age of the b-boys is g, and the average age of the g girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42- year-old teacher) is b+g,
<h3>What is average?</h3>
The average of the values is the ratio of the total sum of values to the number of values.
Here,
The average age of the b-boys is g.
The average age of the g-girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42-year-old teacher) is b+g,
Now,
average of n = 3 (b , g , b+g)
Average = g + b + 42 / 3
b + g = (b + g + 42 ) / 3
3b + 3g = b + g + 42
3b - b + 3g - g = 42
2b + 2g = 42
2 (b + g) = 42
b + g = 21
Thus, the required simplified value of b + g is 21.

Answer:
vertical translation of 5 units in the negative y direction, followed by a vertical translation of 7 units in the negative y direction.
Step-by-step explanation:
given f(x)=6x
f(x)=6x ---> f(x)=6x - 5 (Vertical translation by 5 units in the negative y (i.e downward) direction)
f(x)=6x - 5 ---> f(x)=6x - 5 - 7 (Vertical translation by 7 units in the negative y (i.e downward) direction)
hence it is a vertical translation of 5 units in the negative y direction, followed by a vertical translation of 7 units in the negative y direction.
Answer:
at right angles. ...................electromagnetic waves is propagated when the electric and magnetic field component oscillate at right angles to each other. A changing electric field will produce a changing magnetic field and a changing magnetic field produces a changing electric field.
Step-by-step explanation:
You need to add all of these values together. This is 2 + 9 + 4 which gives 15
There are 180° in a triangle. Divide this by 15.
180/15 = 12
Then multiply this by the largest in the ratio; which is 9.
This is 12 x 9 which = 108°.
The largest angle is therefore 108°.
For reference, the ratio in degrees would look like this:
24:108:48, which adds up to 180°.
