Answers

G = √m-5 /2

g² = m-5 /2

2 × g² = m - 5

2g² = m - 5

2g² + 5 = m

So, m = 2g² + 5

Answer:

m = 2G²+5

Step-by-step explanation:

G²= m-5/2

2g² = m-5

2g² +5 = m

m = 2G²+5

12x-5-7x-11            Combine -5 and -11

12x-7x-15        Now subtract 12x-7x

A dog weighs 60 N on planet Earth. On the moon, he would weigh about
176 (one-sixth) of what he does on Earth. How much does the dog weigh on
the moon?

Answers

Answer:

16.09N

Step-by-step explanation:

Answer:

[tex]\boxed{\purple{\textsf{The weight of the dog on moon is \textbf{10 Newtons. }}}}[/tex]

Step-by-step explanation:

Given that the weight of the dog on the earth is 60N . We need to find the weight of dog on the moon. So we know that the weight of an object is one sixth the weight of an object on the moon. In other words the acceleration due to gravity is one sixth on the moon that of earth. We can use a formula as ,

[tex]\qquad\boxed{\boxed{\sf Weight_{(On \ moon )}= \dfrac{1}{6}\times Weight_{(On \ earth )}}}[/tex]

On substituting the respective values :-

[tex]\sf\implies Weight_{(On \ moon )} = \dfrac{1}{6}\times Weight_{(On \ earth )} \\\\\sf\implies Weight_{(On \ moon )} =\dfrac{1}{6}\times 60 N \\\\\sf\implies\boxed{\pink{\frak{ Weight_{(On \ moon )}= 10 \ Newtons }}}[/tex]

Which ordered pair is a solution of the equation y = 10x?

A. (−6, −60)
B. (8, 90)
C. (8, 70)
D. (−10, −80)

Answers

A is a solution.
Basically, you have to plug in your coordinate to the equation. Plug in -60 for y and -6 for x. Now it should look like:
-60 = 10(-6)
Multiply 10 by -6 to get:
-60 = -60
That is a true statement because -60 equals -60. So, A is a solution to the equation. Hope this helped!
