Find the sum 6/7+7/8

Answer:

1 41/56 or 97/56

Step-by-step explanation:

To add fractions, you must first find a common denominator. The easiest way to do this is to multiply the two denominators, 7 and 8.  The product of these two numbers is 56, your new denominator.  Then, you cross-multiply the numerators.

6/7 + 7/8

7*8 = 56 (denominator)

You multiplied 7 by 8, therefore you must also multiply the 6 by 8 to keep the fractions proportional.  Use the same method to multiply 7 by 7.

48/56 + 49/56

Now that the denominators are the same, you can add the numerators.

97/56

If necessary, you can turn this improper fraction into a mixed number by dividing 97 by 56.  The result is written before the fraction, and the remainder is written over 56.  

1 41/56

C(5,4)(.40)^4(1-.40)^1=5(.4)^4(.6)^1=0.0768

That's 7.68% = 7.7% (rounded)

Note: C(5, 4) is the number of combinations of 5 things taken 4 at a time. You may have seen this written as _5C_4

In general, C(n,r)=\frac{n!}{r!(n-r)!}

Find a close estimate for square root of 45. (without a calculator) Round your answer two decimal places
dusya [7]
You know that 7*7 is 49, and 6*6 is 36. Now you know it will be 6._. 6*7 is 42, so think of that as 6.5^2. You know that it will most likely be less than 6.8 since it is so close to being 7*7, which is 4 above your desired number. This leaves 6.6 to 6.8 as your estimate. Personally, I would go straight in the middle and choose 6.7. 

I hope this helps!

A 160-lb man carries a 5-lb can of paint up a helical staircase that encircles a silo with radius 20 ft. If the silo is 90 ft hi
zheka24 [161]

Weight of man and paint = 160 + 5 = 165 total pounds.

Gravitational force is independent of the path taken so we can ignore the radius of the silo.

Work done = total weight x height

The problem says he climbs to the top so overall height is 90 feet

Work = 165 lbs x 90 ft = 14,850 ft-lbs
