Answer:
About 2,800 hours of sleep per year
Step-by-step explanation:
Sleep per day= 7 hours 45 minutes
7 hours 45 minutes=465 minutes
Sleep per day =465 minutes
Sleep per year=365 days × 465 minutes
=169,725 minutes
There are 60 minutes in one hour
Divide 169,725 by 60 minutes
We have,
169,725/60
=2828.7500000 hours
Total sleep in a year is about 2,800 hours
Answer: 61.16 ft
Step-by-step explanation:
We can think in this situation as a triangle rectangle.
where:
The height of the tree is one cathetus
The shadow of the tree is the other cathetus.
We know that the angle of elevation of the sun is 78°, an angle of elevation is measured from the ground, then the adjacent cathetus to this angle is the shadow of the tree. And the opposite cathetus will be the height of the tree.
Now we can remember the relationship:
Tg(A) = (opposite cathetus)/(adjacent cathetus)
Where:
A = 78°
Adjacent cathetus = 13ft
opposite cathetus = height of the tree = H
Then we have the equation:
Tg(78°) = H/13ft
Tg(78°)*13ft = H = 61.16 ft
Answer The washer costs $539. The dryer cost $450
Step-by-step explanation:
Answer:
2x+7y>=10
Replace x and y with 2 and 1
2*2+7*1>=10
2*2=4
7*1=7
4+7>=10
7+4=11
2x+7y>=10 is a true statement
Because 11 is greater than 10 and it doesnt have to be equal to 10 as long as its greater.
