True or False. Use the information below to answer questions 10, 11, and 12.
The local sporting goods store sells footballs at the following rate.

Number of Footballs n Total Price t
2 $17.00
4 $34.00

10. The price of 6 baseballs is less than the price of 4 footballs. True or False
11. The difference in the price of 1 football when compared to the price of 1 baseball is less than $3
12. The price of 3 footballs is equal to the price of 6 baseballs. True or False

Answer:

True, False, True

Step-by-step explanation:

Calculate the unit price of a football and a baseball

2 footballs cost $17.00 , then

1 football costs $17 ÷ 2 = $8.50

A baseball is 50% of a football, thus

cost of base ball = 50% of $8.50 = 0.5 × $8.50 = $4.25

(10)

4 footballs cost $34.00 ( given in table )

6 baseballs cost 6 × $4.25 = $25.50 < $34

Thus 6 baseballs < 4 footballs is True

(11)

The difference in price = $8.50 - $4.25 = $4.25

Thus the difference in price is greater than $3, not less False

(12)

3 footballs cost 3 × $8.50 = $25.50

6 baseballs cost 6 × $4.25 = $25.50

Thus the costs are equal is True

(a)

If 2 chords of a circle intersect then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord.

(b)

If 2 secants are drawn from an external point to a circle then the product of the measures of one secant's external part and the entire secant is equal to the product of the measures of the other secant's external part and that entire secant.

(c)

If a tangent and a secant are drawn from an external point to a circle , then the square of the measure of the tangent is equal to the product of the measures of the secant's external part and the entire secant.

A radian is defined as the angle subtended at the centre of a circle by an arc equal to the radius of the circle.

1 revolution = 360° = 2π radians

1 radian = \frac{360}{2\pi }

2π

360

≈ 57°

(a)

An inscribed circle of a triangle is a circle drawn inside a circle so the circle barely touches the sides of the triangle.
