Answer:

By calculating water displacement

Step-by-step explanation:

Because Julio knows the volume of water in the graduated cylinder, by dropping the pebble in, he can record the new volume of both the water and pebble. Subtracting the volume of the water from the volume of both will leave him with the volume of the pebble. This technique is water displacement.

Please Help. Lateena solved the equation below. Is her solution correct? Explain why or why not?
bonufazy [111]

Answer:

Not correct

Step-by-step explanation:

Given:

x² - 6x - 7 = 0

The following equation can be solved correctly by factoring Thus,

x² - x + 7x - 7 = 0

x(x - 1) +7(x - 1) = 0

(x - 1)(x + 7) = 0

(x - 1) = 0

x - 1 = 0

x - 1 + 1 = 0 + 1

x = 1

Or

(x + 7) = 0

x + 7 = 0

x + 7 - 7 = 0 - 7

x = -7

Therefore, the solution would be x = 1 or x = -7

Lateena solution is therefore NOT CORRECT because she used a wrong method.

UNO [17]

Answer:

Gross pay = 500.00 + 281.25 = 781.25
