Answer:

√x³=√(x²·x)=x√x

√xy³z=√(x·y²·y·z)=y√xyz

√18x²y=√(3²·2·x²·y)=3x√2y

√32x⁴y²=√(2⁴·2·x⁴·y²)=2²x²y√2=4x²y√2

2√16x⁷y³z⁴=2√(2⁴·x⁶·x·y²·y·z⁴)=2³x³yz²√xy=8x³yz²√xy

-3√180x⁵y=-3√(3²·2²·5·x⁴·x·y)=-3(3)(2)x²√5xy=-18x²√5xy

5√108xyz²=5√(2²·3²·3·x·y·z²)=5(2)(3)z√3xy=30z√3xy

3x√xy¹⁰z⁷=3x√x·y¹⁰·z⁶·z)=3xy⁵z³√xz

x²√x³y²=x²√(x²·x·y²)=x²·x·y√x=x³y√x

90 students take a test.
Anika [276]

Answer:

Step-by-step explanation:

If there are 90 students and the ratio of boys to girls is 3:2, that means 3x+2x=90

Combine like terms: 5x=90

x=18

2x (girls)=36

3x (boys)=54

1/3 of the boys scored full marks, so 54/3=18 boys scored full marks

The number of girls who scored full marks is half of the number who did not score full marks means that 1/3 of the girls scored full marks. 36/3=12, so 12 girls scored full marks.

(I don't know what the question is sorry if it's incorrect but there's not enough information)

Hope this helps!

Maslowich

Answer:

The total change that will likely occur in 2 years is =-3\frac{2}{3} mg/L        

Step-by-step explanation:

Given : The first year, they found the chloride concentration changed by -1\frac{3}{5} mg/L .

It is estimated that the chloride concentration will change -2\frac{1}{15} mg/L the next year.

To find : What is the total change that will likely occur in 2 years?

Solution :

The chloride concentration changed by -1\frac{3}{5}=-\farc{8}{5} mg/L in first year.

The chloride concentration will change -2\frac{1}{15}=-\frac{31}{15} mg/L the next year.

The total change that will likely occur in 2 years is

=-\frac{8}{5}+(-\frac{31}{15})

=\frac{-24-31}{15}

=\frac{-55}{15}

=\frac{-11}{3}

In a mixed fraction - =-3\frac{2}{3} mg/L
