Answer:
4/5 + 3/4 = 
or 1.55
Step-by-step explanation:
This can be solved by first finding the highest common factors of denominators of the two fractions, i.e. 4 and 5.
The highest common factor of 4 and 5 can be found by multiplying the two numbers as follows:
The highest common factor of 4 and 5 = 4 * 5 = 20
This can now be used to solve 4/5 + 3/4 as follows:
4/5 + 3/4 = ((4 * 4) + (5 * 3)) / 20 = (16 + 15) / 20 = 31 / 20 = or 1.55
Therefore, we have:
4/5 + 3/4 = or 1.55
Answer:
The perimeter of the new square is three times the perimeter of the first one.
Step-by-step explanation:
You just need to put in an example number to figure this out.
Lets say one square has a side of two, and another a side of 6.
Perimeter of square 1: 8
Perimeter of square 2: 24
24 is three times more than 8.

95% confidence interval is given by
x - 2D , and x+ 2D
For 99% confidence interval is
x - 3D , and x + 3D
x = 100000
D = 2000
Then calculate
100000 - 3•2000= 94000
and
100000 + 3•2000= 106000
Now find √D = 44.72
Then interval is
100000 - 44.72 ,. And. 100000 + 44.72
99,956 lower limit and. 100472 upper limit
Then we see that theres only one interval ,
that is between thes 2 limits
ANSWER Is OPTION C) ) ($99.996.46, $100,003.55)
Answer:
the last one
Step-by-step explanation:
there is a total of 80 items
34+24+10+11=80
= approx. 12.5% so a is wrong
= approx. 13.75% so b is wrong
there were 24 brownies sold and 
so c is incorrect
there were 10 cookies sold which does equal 
so the last one is right
