Answer:

A

Step-by-step explanation:

To find the best equation, we simply substitute the values of a, b, and c into the given equations.

a = 21

b = 5

c = 36

a=\dfrac{7}{10}b\sqrt{c}

21=\dfrac{7}{10}5\sqrt{36}

21=\dfrac{7}{10}5(6)

21=\dfrac{7}{10}30

21=(0.7)30

21=21

julsineya [31]
What is 48.75 as a fraction?
To write 48.75 as a fraction you have to write 48.75 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
48.75 = 48.75/1 = 487.5/10 = 4875/100

And finally we have: 
48.75 as a fraction equals 4875/100

HELP PLEASE If L is the line through the point (-3,5) having a slope of 2/3 . Complete the equation of L
nalin [4]

point slope form  (y-y1) = m(x-x1)

y-5=(2/3)(x-(-3))

y-5=(2/3)(x+3)                    add 5 to each side and distribute

y= 2/3x +2/3 *3 +5

y = (2/3)x +2 +5  

y = (2/3) + 7
