You are working in a lab and you need a solution of 22% acid. In the cupboard, you find a 10% and a 30% solution, but not a 22%
disa [49]

The volume of 10% solution will be 6 l and 9 litre of the 30 % solution will be taken.

<h3>What is Volume ?</h3>

Volume is the space occupied by a three dimensional object .

The concentration of solution required is 22% acid

The concentration of solution available is 10% and 30%

The total volume required is 15 liters

The formula for making a mixture is

Concentration = ( m₁x₁ +m₂x₂) / (x₁+x₂)

22 = (10 * x + 30 *(15 -x))/( 15)

10 x + 450 - 30x =330

-20x = -120

x = 6

The volume of 10% solution will be 6 l

and 9 litre of the 30 % solution will be taken.

Two supplementary angles have measurements of (3x)° and (10x – 15)°. What are the measures of the
Oxana [17]

Sorry for the way it came out but the Answer:

2

x

+

5

=

43

∘

3

x

−

10

=

47

∘

Explanation:

A complementary angles means angles that add up to

90

degrees. The two angles given in the question are complementary angles.

So

Our first angle

(

2

x

+

5

)

plus the second angle

(

3

x

−

10

)

is equal to

90

degrees

(

2

x

+

5

)

+

(

3

x

−

10

)

=

90

Now we solve for

x

, first we add up the like terms

2

x

+

3

x

+

5

−

10

=

90

5

x

−

5

=

90

Add

5

to both sides

5

x

=

95

Divide both sides by

5

we get

x

=

19

Now and after we find

x

we substitute it to get our two angles

2

x

+

5

=

2

(

19

)

+

5

=

43

∘

3

x

−

10

=

3

(

19

)

−

10

=

47

∘

Hope it helps :)

Tom and David get their haircut at the barber shop on Saturdays.Tom gets his hair cut every 3 weeks. David gets his hair cut eve
MrMuchimi

Answer:

On Saturday, when 12 weeks passed

Step-by-step explanation:

Tom gets his hair cut every 3 weeks.

David gets his hair cut every 4 weeks.

Find the least common multiple of numbers 3 and 4:

3=3\\ \\4=2\cdot 2\\ \\LCM(3,4)=3\cdot 2\cdot 2=12

This means that Tom and David will get their hair cut on the same day at 12th week (if the first week when they started has number 0).

You can think in another way:

Tom gets his hair cut every 3 weeks. He got his hair cut after 3 weeks, after 6 weeks, after 9 weeks, after 12 weeks passed.

David gets his hair cut every 4 weeks. He got his hair cut after 4 weeks, after 8 weeks, after 12 weeks passed.
