If it is 12:17 what time was it 45 minutes ago (plz say how you got awnser)
Answers
Answer 1
Answer:
you have to subtract 17 from 12:17 and 45 so now the problem is 12:00 and 28 minutes. Now, just subtract 28 from 60 and you get 32. The answer is 11:32
A spinner has 7 identical sections. Two sections are blue, 1 is red, and 4 of the sections are green. Suppose the probability of an event happening is 2/7 . What does each number in the ratio represent? What outcome matches this probability?
Answers
The numerator represents the chance of landing on the colour, and the denominator represents the number of spots you could land on. You have a 2 out of 7 chance to land on blue because there are 2 blue spots. This means that for every 2 times out of 7 spins you would land on blue.
HELP I tried it but I don't see where this is going, and I don't even know what equation I would put to finish.. please help
Answers
find the equations that tell their height starting+growth=current height starting=1 growth=2 times number of months grown so 1+2m=h
another one is 11 and grows at 1 per month 11+1m=h
when will heights be equal? set them equal and solve for the numberof months 1+2m=11+1m minus 1m both sides 1+m=11 minus 1 m=10
answer is 10 months
A box is filled with pennies, nickels, and dimes in a ratio of 2:3:4. If the total number of coins in the box is 1620, how many pennies are in the box
Answers
We could say that the number of pennies is 2x, nickels are 3x, and dimes are 4x. Adding all of them together, we get 2x+3x+4x=9x. We also know that 9x=1620 because the total amount of coins is 1620. Dividing by 9 on both sides we get x=180. Pennies equal 2x= 2*180=360
NEED HELP ASAP !!Points V, W, X, Y, and Z are graphed on a number line. The coordinate of point V is 3.
What points are at a distance of 7 units from point V?
Choose all answers that are correct.
A. W = –7 B. X = –4 C. Y = 4 D. Z = 10
Answers
So,
We need to find all points that are 7 units from point V. We can just test which ones are 7 units away by taking the absolute value of the different between their coordinates.
A. W = -7 |-7 - 3| = |-10| ≠ 7
B. X = -4 |-4 - 3| = |-7| = 7
C. Y = 4 |4 - 3| = |1| ≠ 7
D. Z = 10 |10 - 3| = |7| = 7
Points X and Z are 7 units from point V; in fact, points X and Z are the only points at a distance of 7 units from point V.
-- You've told me that there are 5 houses on a map, and
-- you've told me the address of one house.
-- You won't show me the map, but
-- you're asking me which houses are 7 miles from that one.
Can you see what's missing here ?
You haven't told me a thing about any of the other points/houses. I don't even know if any of the others are in the same city as ' V ' is, or even on the same planet !
