Answer:
Your movie marathon will last 6 hours.
Step-by-step explanation:
This question can be solved using a rule of three.
Each movie lasts 
hours. How much do 4 movies last?
So
1 movie - 1.5 hours
4 movies - x hours
x = 4*1.5 = 6
Your movie marathon will last 6 hours.
Answer:
2/8 or 1/4
Step-by-step explanation:
2/8 or 1/4 because the spots on the spinner are blue out of 8 is 2/8 or 1/4
(x,y) -> (-y, x) This is a symmetry with respect to y=x, followed by a reflection across the y axis. Congruent.
(x,y) -> (x-2, y-1/2) This is a translation, but it follows different rules for each coordinate. Not congruent.
(x,y) -> (2x, 2y) This is a dilation. The resulting triangle will be similar, but not congruent. Not congruent.
(x,y) -> (-x, y) This is a reflection across the y axis. Congruent.
(x,y) -> (1/2x, 1/2y) This is a dilation. The resulting triangle will be similar, but not congruent. Not congruent.
Answer:
yards of wire left on the roll = 500 - r(3)
Step-by-step explanation:
9 feet = 3 yards we need to find how much wire is left on the roll after she builds a certain amount of robots. she uses 9 feet or 3 yards per robot so we have to multiply the amount of robots (r) by 3 yards and subtract that from 500 yards or the total amount of wire she has and that gives us the total amount of wire she has left. Hope this helps.
