9. A movie theater sells small and large pretzels. A small pretzel costs $2. A large pretzel costs $4.50. A total of 50

seraphim [82]

Answer:

30 small pretzels were sold that night.

Step-by-step explanation:

x = small pretzels

y = large pretzels

x + y = 50

2x + 4.5y = 150

x + y - y = 50 - y

x = 50 - y

2(50 - y) + 4.5y = 150

100 - 2y + 4.5y = 150

2.5y = 50

------- -----

2.5 2.5

y = 20

x + 20 = 50

x + 20 - 20 = 50 - 20

x = 30

kompoz [17]

Step-by-step explanation:

The pendulum swings over an angle of 2×(2°30') or 5° so we need to convert this to radian measure first:

$5° × \left(\dfrac{\pi}{180°}\right) = 0.0873\:\text{rad}$

so the arc length is given by

$s = r\theta = (50\:\text{cm})(0.0873\:\text{rad}) = 4.36\:\text{cm}$

Answer:

3 : 4 = 12 : 6

2 : 5 = 30 : 75

7 : 9 = 14 : 18

8 : 3 = 64 : 24

Step-by-step explanation:

3 : 4 = 12 : ?

3/4 = 12/?

3 x ? = 12 x 4

3 x ? = 48

? = 48 ÷ 3 = 16

2 : 5 = 30 : ?

2/5 = 30/?

2 x ? = 30 x 5

2 x ? = 150

? = 150 ÷ 2

? = 75

7 : 9 = ? : 18

7/9 = ?/18

7 x 18 = ? x 9

126 = ? x 9

? = 126 ÷ 9

? = 14

8 : 3 = 64 : ?

8/3 = 64/?

8 x ? = 64 x 3

8 x ? = 192

? = 192 ÷ 8

? = 24
