Reflect across the y axis and moved through the translation x = 2
The parents could have 3 boys and 3 girls in 400 ways
<h3>How to determine the number of ways?</h3>
The given parameters are
Children, n = 6
Boys, r = 3
Girls, r =3
The number of combination is:
So, we have:
Apply the combination formula
This gives
Ways = 400
Hence, the parents could have 3 boys and 3 girls in 400 ways

If area of a circle can be expressed by the formula A=πr², where r is the radius of a circle. then √A/π is the radius in terms of the area of the circle.
<h3>What is Circle?</h3>
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given,
The area of a circle can be expressed by the formula A=πr²
r is the radius of a circle
We need to find the radius in terms of the area of the circle
A=πr²
Divide both sides by π.
A/π=r²
Now take square root on both the sides
√A/π=r
Hence, √A/π is the radius in terms of the area of the circle.

Answer: 67.5 mph
Step-by-step explanation:
The formula for speed is:
= Distance / Time
Distance = 658.125 miles
Time will need to be converted to a decimal. You may convert only the minutes into hours as the hours are already hours.
= 45/60 minutes
= 0.75 hrs
= 9 + 0.75
= 9.75 hours
Speed = 658.125 / 9.75
= 67.5 mph
The answer is 2
Because 2-3=-1
