Suppose a chemist combines a 25% acid solution and a 50% acid solution to make 40 L of 45% acid solution. How many liters of each solution did she use? Use the blanks below to fill in your numerical answers.

Answer: the first option

Step-by-step explanation:

If y=2x+4 and y also equals 3x+1, then by the transitive property, 2x+4=3x+1

It’s like saying if a=b and b=c, then a=c (that’s the transitive property)

Answer:

n = 6

Step-by-step explanation:

[tex]\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{m}*a^{n}=a^{m+n}\\\\[/tex]

[tex]\frac{(-4)^{10}}{(-4)^{n}}=(-4)^{2}*(-4)^{2} \\\\(-4)^{10-n}=(-4)^{2+2}\\\\(-4)^{10-n}=(-4)^{4}[/tex]

Compare the exponents,

10 - n = 4

10 = 4 +n

10 - 4 = n

6 = n

Answer:

Step-by-step explanation:

The correct system of equations which is the number of nickels and dimes that Lucas has in the jar is:

n + d = 30

0.05n + 0.10d = 2.10

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Lucas has a jar of coins that only contains nickels and dimes. He has 30 pennies in the jar, which is worth $2.10.

Let represents the number of nickels, n,

And the number of dimes, d, that Lucas has in the jar

The system of equations to find the number of nickels and dimes that Lucas has in the jar is:

n + d = 30

0.05n + 0.10d = 2.10

This system can be used to solve for the values of n and d. The first equation represents the total number of coins, and the second equation represents the total value of the coins in the jar.

Answer: 4 roots

Step-by-step explanation: Just look at the highest power and that will tell you the amount of roots, unless there are imaginary roots

Step-by-step explanation:

[tex]log \frac{a}{b} = loga - logb[/tex]

logx - log3 = log(x-2)

[tex] log( \frac{x}{3} ) = log(x - 2)[/tex]

[tex] \frac{x}{3} = x - 2[/tex]

x = 3(x - 2)

x = .......

Answer:

They are equal to one another

Step-by-step explanation:

1/2 is equal to .5, so id you have 6.5 on one side and 6.5 on the other, they are equal.

Answer: =

6 [tex]\frac{1}{2}[/tex] = 50/100

=6.5

so 6.5 = 6 [tex]\frac{1}{2}[/tex]

Answer:

y = ~-0.43x + 1.43

Step-by-step explanation:

You are solving for Y.

3x + 7y = 10

7y = -3x + 10 ^ Subtraction Property of Equality

y = ~-0.43x + 1.43 ^ Division Property of Equality

Answer:

x=15, y=12, z=20

Step-by-step explanation:

y is the geometric mean of the two segments it divides.

9 · 16 = y^2

y=12

Use the pythagorean theorem to find x and z.

16^2 + 12^2 = z^2

z^2 = 400

z=20

9^2 + 12^2 = x^2

x^2 = 225

x=15

Answer:

[tex]\frac{25}{100}[/tex]

Step-by-step explanation:

Hey there !!!!!

to find the correct answer to this question  you just divide :

the options are  25/10 , 2/5 , 10 / 25 and 25/100

so, you divide each one of them :

25/10 = 25 ÷ 10

2/5 = 2 ÷ 5

10/25 = 10÷25

25/100 = 25÷100

if you divide each one of them:

25 ÷ 10 = 2.5

2 ÷ 5 = 0.4

10÷25 = 0.4

25÷100 = 0.25

therefore:

25/100 is the answer

have a wonderful day

Answer:

Exponential functions are patterns that get continuously multiplied by some number. It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.

Step-by-step explanation:

Answer:

exponential growth

Answer:

(5,9) is a reflection of (-5,9). One of the x values are positive while the other is negative.

Answer:

Step-by-step explanation:

I'll assume that you meant

(8/13) ln 3 = ln h/12

Applying rules of logs, we get:

(8/13) ln 3 = ln h - ln 12

                = ln h - ln 3 - ln 4         <=  because ln b*c = ln b + ln c

Then (8/13) ln 3 + ln 3 = ln h - ln 4, or

(21/13) ln 3 + ln 4 = ln h  

3^(21/13) * 4 = h                 <=  because ln b*c = ln b + ln c

Answer:

Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, πu + 5v = 9 and 3 = 2 x – 7y. Note that you can put these equations in the form 1.2s + 3t – 5 = 0, p + 4q – 7 = 0, πu + 5v – 9 = 0 and 2 x – 7y – 3 = 0, respectively.
