If it's 5cm x 5 cm x 5cm
Volume is a3
so 125cm
8 hours. 125 - 5 = 120. 120 / 15 = 8. Kelly will need to tutor for 8 hours minimum to buy the dress.
Answer:
C:
Step-by-step explanation:
Volume of rectangular pyramid = (1/3)(l×w×h)
Where l is length , w is width and height is h
V = (1/3)(12×10×8)
V = (1/3)960
V = 320 cubic inches
15x - 10 where x is equal to the number of weeks would respresent the situation above. This is because he gains 15 cards every week and gave ten cards to James once.
If it has only been one week, the expression will be 15 - 10 because 15 × 1 = 15.
I hope this helps!
Answer:
The solution set is {4, -1}
Step-by-step explanation:
6x²- 18x -18 = 6
6x²- 18x -18 - 6 = 0
6x²- 18x -24 = 0
6(x² - 3x - 4) = 0
6(x - 4)(x + 1) = 0
6 = 0 not true
x - 4 = 0 ; x + 1 = 0
x = 4 x = - 1
The solution set is {4, -1}
