Answer:
- 22
Step-by-step explanation:
A fall of degree = 0.5 degrees is represented as
- 0. 5 degrees
The temperature at 2 : 00 is therefore
- 21.5 - 0.5 = - 22 degrees
Answer:
x=24
Step-by-step explanation:
6×(5/6)x +6(10)=6(30)
5x +60=180
5x +60-60=180 - 60
5x=180 -60
5x=120
5x/5 =120/5
x=24
If we represents a book's cost as x, that would mean that 5*x would represent the cost of 5 books (as x+x+x+x+x=5x) and 4x would be 4, resulting in 5x+4x=9x. After that, we get that 19 books is 19x as the cost, but since Agnus gets a 10 dollar discount, it's 19x-10. After that, to combine the two, we notice that Agnus still spends 5$ more than what they spent combined (9x) so we get that 9x+5=19x-10. Subtracting 9x from both sides, we get 10x-10=5. Adding 10 to both sides there, we get 10x=15 and we can divide 10 by both sides to get x=1.5
Answer:
The day would be 3.125 seconds longer in 25 centuries.
Step-by-step explanation:
Let's break it down.
Each year, 1250 microseconds are added to the planet's day.
We need to find how long a day would be in 25 centuries.
A century is 100 years.
A second is 1,000,000 microseconds.
The day would be 3.125 seconds longer in 25 centuries.
(1 & 2/3) ft = (1 ft) + (2/3 ft)
(1 & 2/3) ft = 12 inches + 12*(2/3) inches
(1 & 2/3) ft = 12 inches + 8 inches
(1 & 2/3) ft = 20 inches
If the tree grows 5 inches per year, then it will take 4 years to get to 20 inches since 5*4 = 20. You can also divide to get 20/5 = 4.
So it takes 4 years for the tree to grow 1&2/3 feet tall.
