26. If Sarah read 1/3 of 15 books, she read 5. 40% of 15 is 6, so Dana read more books.
27. The answer is A.
28. The first room is rented for $220 for 12 months. 220x12=2640 If the total rent from both rooms is $5820, then we subtract 2640 from 5820, then divide by 12. 5820-2640=3180 3180/12=265. Judith charged $265 for the second room.
29. The base amount for the parts is $150. If he is charged $50 dollars an hour, and he had to pay $375, then we know that he was charged for a half hour. 375-150=225. 225 means that he was charged for 4 1/2 hours
Answer:
32/4= 8 (there is a factor of 8 between x and y at all times)
128/8 = 16 (divide y by 8 to find out what x is.
x= 16 when y= 128
Step-by-step explanation:
Answer:
1/11
Step-by-step explanation:
If there are 11 counters and there's only 1 white one, that makes it to where there's only a 1 in 11 chance of you choosing that one white counter.
Answer: X= i, -i, 2i, -2i
Step-by-step explanation:
The roots are x values when the graph intersects the x axis.
8 and 15 are the lengths of the legs.
The tangent is the ratio of the lengths of legs.
In general, tan x = opp/adj
You have 8/15, so here 8 is the opposite leg and 15 is the adjacent leg.
Angle A is the right angle, so that is not it.
For which acute angle, B or C, is 8 opposite and 15 adjacent?
Answer: for angle B.
Therefore, 8/15 must be tan B.
