Answer:

Step-by-step explanation:

distance = time * speed

4.9 =  1 second* speed

speed = 4.9/1 = 4.9 cm/sec

time = 15 1/2 = 31/2

distance = 31/2 *  4.9 = 75.95 cm

Answer:

75.95cm

Step-by-step explanation:

<u>4.9 multiplied by 15 will represent the 15</u> <u>seconds</u>

4.9 • 15 = 73.5

<u>4.9 divided by 2 will equal the 1/2 seconds</u>

4.9 ÷ 2 = 2.45

<u>add them all together</u>

73.5 + 2.45 = 75.95 cm

Line segment BC will be reflected over line m to form line segment BC. Which of the following statements must be true?
Len [333]

Answer:

<u>Option A</u>

Step-by-step explanation:

To reflect line segment BC over line m, BB' will be perpendicular to the line m

and line m bisector of BB'.

<u>So, the correct answer is option A</u>

A) Line m is the perpendicular bisector of line segment BB' and the line segment CC'

<u>Option b is wrong</u> , it is impossible for the line B'C' to be perpendicular to line BC. B'C' is the image of BC.

<u>Both option c and d is wrong</u> because the perpendicular distance from b to the line m not equal to the perpendicular distance from c to the line m.

Jason and his children went into a movie theater where they sell drinks for $4 each and pretzels for $5 each. Jason has $65 to s
klemol [59]

Answer:

Number of drink = 5

Number of pretzel = 9

Step-by-step explanation:

Given:

Cost of each drink = $4

Cost of each pretzel = $5

Total money = 65

Total number of drink and pretzel = 14

Find:

Number of drink and pretzel

Computation:

Number of drink = x

Number of pretzel = 14 - x

So,

x(4) + (14-x)5 = 65

4x + 70 - 5x = 65

x = 5

Number of drink = 5

Number of pretzel = 14 - x

Number of pretzel = 14 - 5 = 9
