Robin and Shaon got 5/6 and 4/5 of the total marks. Robin obtained 30 more marks than Shaon.What is the total marks?
Natasha2012 [34]

Answer:

Robin= 750

Sharon= 720

Step-by-step explanation:

let the total marks obtained be X

from question, Robin = 5X/6

Shaon= 4X/5

then, 5X/6= 4X/5+30

or, 5X/6= 4X+150/5

or 25X=24x+900

or,X= 900

therefore robin=750

Shaon = 720

**100 POINTS**I WILL MARK AS BRAINLIEST IF YOU GET IT CORRECT!
Akimi4 [234]

Answer:

As we know:

Direct variation => y = k*x, k is constant ( y/x = k = constant)

Inverse variation => y = k/x, k is constant (y*x = k = constant)

X - 1 2 5 10

Y - 6 12 30 60

Check the first 2 pair of X, Y:

(the remaining pair of value would show the same tendency)

X1 x Y1 = 1 x 6 = 6

X2 x Y2 = 2 x 12 = 24

=> X x Y is not a constant

=> Not an inverse variation.

=> B and D is incorrect

Otherwise, we have:

Y1/X1 = 6/1 = 6

Y2/X2 = 12/2 = 6

=> Y/X = 6

=> A direct variation with k = 6

=> y = 6x

=> Option C is correct

Hope this helps!

:)

Express the following linear equations in the form ax+by+c= 0 and indicate the values of a, b and c in each case: (1) y = x/5​
EleoNora [17]

Answer:

Did the question get cut off?

a = -(1/5)

b = 1

c = 0

Step-by-step explanation:

y = x/5 may be rewritten as y = (1/5)x

y = (1/5)x

y - (1/5)x = 0

- (1/5)x + y + 0 = 0

   ax  +   by   + c = 0

a = -(1/5)

b = 1

c = 0

Devonte used the change of base formula to approximate log Subscript 8 Baseline 25. Which expression did Devonte use?.
scZoUnD [109]

Answer:

I think I did this. I think the answer choices are:

Log StartFraction 8 Over 25 EndFraction

StartFraction log 8 Over log 25 EndFraction

log StartFraction 25 Over 8 EndFraction

----> StartFraction log 25 Over log 8 EndFraction

So the answer is D
