5\dfrac{42}{170}-3\dfrac{80}{170}=(5-3)+\left(\dfrac{42}{170}-\dfrac{80}{170}\right)\\\\=2+\left(-\dfrac{38}{170}\right)=2-\dfrac{32}{170}=1\dfrac{170}{170}-\dfrac{38}{170}\\\\=1\dfrac{170-38}{170}=1\dfrac{132}{170}=1\dfrac{132:2}{170:2}=1\dfrac{66}{85}


5\dfrac{42}{170}-3\dfrac{80}{170}=4\dfrac{170+42}{170}-3\dfrac{80}{170}\\\\=(4-3)+\left(\dfrac{212}{170}-\dfrac{80}{170}\right)=1+\dfrac{212-80}{170}\\\\=1+\dfrac{132}{170}=1\dfrac{132:2}{170:2}=1\dfrac{66}{85}

Newton's Law of Gravitation:

Statement: According to this law, when two mass bodies are separated at finite distance then there must be an attractive force experience by them which is directly proportional to the product of their masses and inversely proportional to the square of their separation.

Consider two mass bodies m1 & m2 be kept at distance d. Then the force of attraction F is given as

                            Fam_{1}.m_{2}

                                 Fa1/d^2

Now, from above equations, we have

                          Fa\frac{m_{1}m_{2}}{d^2}

or,                           F=G\frac{m_{1}m_{2}}{d^2}

Here         G=6.67*10^{-11}Mm^2kg^{-2}   is the universal gravitational constant.

If k is the midpoint of hj and hk =x+6 and hj =4x-6 then What does kj equal
leva [86]
Given: k= midpoint
hk=x+6
hj=4x-6

Remember midpoint cuts the segment hj in equal parts that means hk=kj and hk+kj=hj
hk+hk=hj
2hk=hj

2hk=hj
2 (x+6)=(4x-6)
2x+12=4x-6
2x-2x+12=4x-2x-6
12=2x-6
12+6=2x-6+6
18=2x
18/2=2x/2
9=x

hk=kj=x+6=(9)+6=15
kj=15

Antonio ate 1/4 of a box of cereal, Jamie ate 1/8 of the box, Marianna ate 8/16 of it. What are the quantities in this situation
Molodets [167]

Answer:

so im not sure what youre asking but hopefully i can help you with this a little. if you change the fractions to all have the same denominator, it will be easier for you to solve. since they can all have eight as a denominator, antonio wouldve eaten 2/8 of a box of cereal, jamie 1/8, and marianna 4/8. hope that helps a little :)
