Answer: The basketball will sell for $21
.
Step-by-step explanation:
Hi, to answer this question, first, we have to multiply the cost of the basketball (10) by the percent markup in decimal form (divided by 100).
Mathematically speaking:
10 x (110/100) = $11
Now, we have to add the markup amount (11) to the cost (10) to obtain the selling price:
10 +11 = $21
The basketball will sell for $21

Answer:
1/2(x²) square units
Step-by-step explanation
From the question,
Area of a Square(A) = L²
A = L²................. Equation 1
Where L = Lenght of the square
If the diagonal of the square is x,
Using pythagoras theorem,
a² = b²+c².................. Equation 2
Wherer a = x, b = c= L
Therefore,
x² = L²+L²
x² = 2L²
L² = x²/2
L = √(x²/2)
Substitute the value of L into equation 1
A = [√(x²/2)]²
A = x²/2 square unit.
A = 1/2(x²) square unit.
The right option is 1/2(x²) square units
A standard line equation takes the form of y=mx+b
m= the slope so we see that 2 is next to x in your example
A) Slope = 2
Perpendicular lines will have the negative reciprocal of the original equation's slope
2 -> -
B) 
<span>3 girls and 2 boys took part in a quiz
total all students took the quiz = 3 + 2 = 5 students
</span><span>the girls scored a total of 21 marks and the boys scored a total of 19
