Total Weight of sand =90Kg
Ratio in which sand is divided= 2:3:7
Let x be the fundamental unit in which the sand is divided.
By conservation of mass.
2x +3x + 7x= 90
=> 12x =90
=> x=90/12 =45/6=15/2=7.5
So Amount of sand in small bag=2×7.5=15Kg
Amount of sand in medium bag =3×(7.5)=23.5Kg
Amount of sand in Large bag =7×(7.5)=52.5 Kg
Hope it helps...

Answer:
The camera is sold for $ 59.26.
Step-by-step explanation:
From the statement we understand that the new price of the camera () is calculated by:
(1)
Where:
- Price after increase, measured in US dollars.
- Increase rate, expressed in percentage.
If we know that and , then the new price of the camera is:
The camera is sold for $ 59.26.
A) x^5/6 ≠ 5√6, Because 5 is in numerator & 6 in denominator in exponential expression so it can be in direct expression.
It is False.
b) (16)^1/4 = 2.
It is False
c) a^2/7 + a^4/7 = a^2/7+4/7 = a^6/7
It is False.
d) Here, powers are not equivalent.
Again, It is False
e) (27x^6)^2/3 = 27^2/3 x^12/3
= 9x^4
It is True.
13) Here, expression would be: a^2/3
In short, Your Answer is Option B
14) ∛8x^6
= ∛8 x^6/3
= 2x²
In short, Your Answer would be Option C
Hope this helps!
j = # of jars
b = # of buckets
y = total # of rocks
2j + 3b = y (2 rocks per jar, 3 rocks per bucket)
Because Joy has 3 jars you can plug 3 in for "j", and because she has 4 buckets you can plug in 4 for "b"
2(3) + 3(4) = y
6 + 12 = y
18 = y
Slope-intercept form is y = mx + b
So we can manage to do this:
(y - yo) = m.(x - xo)
Where (x, y) and (xo, yo) are points of this line, this way we can discover the slope.
(7 - 2) = m.(1 - 0)
5 = m
m = 5
So,
y = 5x + b
Now we still have to use (y - yo) = m.(x - xo), but this time we will put only 1 point and the slope.
(y - yo) = m.(x - xo)
(y - 2) = 5.(x - 0)
y - 2 = 5x
y = 5x + 2
So, this is the line in slope-intercept form.
