A scientist has a container of 2% acid solution and a container of 5% acid solution. How many fluid ounces of each concentration
algol [13]

Let 'a' be the number of ounces of 2%-solution in the 25-ounce mixture

and 'b' be the number of ounces of 5%-solution in the 25-ounce mixture.

Since, fluid ounces of each concentration should be combined to make 25 fl oz.

So, a+b=25 (Equation 1)

And, a container of 2% acid solution and a container of 5% acid solution should be combined to make 25 fl oz of 3.2% acid solution.

So, a of 2% + b of 5% = 3.2% of 25

(a \times \frac{2}{100})+(b \times \frac{5}{100})= 25 \times \frac{3.2}{100}

(0.02a)+(0.05b)= 0.8

Multiplying the above equation by 100, we get

2a+5b=80 (Equation 2)

Substituting the value of a=25-b in equation 2, we get

2(25-b)+5b=80

50-2b+5b=80

50+3b=80

3b=30

b=10

Since, a=25-b

a= 25-10

a=15.

So, 15 fluid ounces of 2% solution combined with 10 ounces of the 5% solution to create a 25-ounce mixture at 3.2% concentration of acid.

Complete the equation, by supplying the missing exponent.<br> m•n2•m3= m 11n2
MaRussiya [10]

Given:

Consider the given equation is:

m^?\cdot n^2\cdot m^3=m^{11}\cdot n^2

To find:

The missing exponent.

Solution:

Let x be the missing exponent. Then the given equation can be written as

m^x\cdot n^2\cdot m^3=m^{11}\cdot n^2

It can be rewritten as:

(m^x\cdot m^3)\cdot n^2=m^{11}\cdot n^2

m^{x+3}\cdot n^2=m^{11}\cdot n^2      [\because a^ma^n=a^{m+n}]

On comparing the coefficient of m, we get

x+3=11

x=11-3

x=8

Therefore, the value of the missing exponent is 8. So, the complete equation is m^8\cdot n^2\cdot m^3=m^{11}\cdot n^2.

If f(x) = 8x2 + 4x - 12. Find f(2)<br> f(2)=
posledela

Answer:

f(2) = 28

Step-by-step explanation:

\rm f(x) = 8 {x}^{2}  + 4x - 12

\rm Evaluate \:  8 x^2 + 4 x - 12 \:  where  \: x = 2: \\  \\  \rm \implies f(2) = 8 \times {2}^{2}  + 4 \times 2 - 12 \\  \\   \rm \implies f(2) = 8 \times 4 + 8 - 12 \\  \\   \rm \implies f(2) = 32 - 4 \\  \\   \rm \implies f(2) = 28

Find the 7th term in the sequence -10,-6,-2,2...
jeyben [28]

1st term = -10

2nd term = -6

3rd term = -2

4th term = 2

5th term = 6

6th term = 10

7th term = 14


The reason how I got 14 for the 7th term is because, i added 4 to each term.


Hope this helps!
