We may log in directly in our scientific calculator the given value ln 7 and get an answer of 1.9459. On the other hand, we can rewrite the expression as,
log to the base e or 7 = x
which can be written as,
e^x = 7
The value of x from this is still equal to 1.9459.
Answer:
The following expressions become negative:
- 3) x times y = xy = (1)(-2) = -2
- 4) x divided by y = x/y = 1/-2 = -2
Step-by-step explanation:
Given
Computing by substituting x = 1, and y = -2
1) x+y = 1+(-2) = -1
2) x - y = 1 - (-2) = 1+2 = 3
3) x times y = xy = (1)(-2) = -2
4) x divided by y = x/y = 1/-2 = -2
It is clear from the above calculations that when we put x = 1, and y=-2 then the expressions (x+y), (x times y), and (x divided by y) become negative.
Therefore, the following expressions become negative:
- 3) x times y = xy = (1)(-2) = -2
- 4) x divided by y = x/y = 1/-2 = -2
Answer: 15 feet
Step-by-step explanation:
First you start with 2ft and 6in and convert it all into into inches.
If you know that 1 ft=12in then you know that 2 feet is the same as saying
12+12=24. If you don't understand use this chart-
1 ft=12in
2ft= 24in
3ft= 36in
4ft =48in
5ft= 60in
6ft= 72in
see I am counting by 12's.
Now take 2ft and convert it into inches. That would be 24 in (look in the chart).
now take the 24in(2ft) and add it to the 6in. So 24+6 =30
So now you know that one piece of pipe is 30in long.
But in the text it states that Don has 6 pieces, so...
because it says that he has 6 pieces of pipe then you are going to take that and multiply that number(6) by how long each piece is. look up and it shows how long each pieces is. They are all each 30in long. Take 30 and multiply that by 6 because there are 6 pipes and you will get 120in.
But it says that they need an answer of feet and inches or just feet if it exactly a some sort of foot like 43feet or 2 feet.
So then we are going to convert 180 into feet by dividing 180 by 12 and you get 15. So the answer is 15.
I hope this helps. Have fun learning!!
Answer: 8
Step-by-step explanation:
we know the area of a circle is
A=π r²
50.24= 3.14* r²
50.24/3.14=r^2
16=r^2
r=sqrt 16=4
diameter is 2r=2*4=8
