How many quarts of a 50% solution of acid must be added to 20 quarts of a 20% solution of acid to obtain a mixture containing a 45% solution of acid?

Answers

Answer 1

Answer Using the method of alligation. 40.0= 20/(10/20) qts of 50% solution to add to your 20 qts of 20% solution. 60.0= (20+40.0) qts of the final 40% solution.

what does the a in y=a(1+r)x represent?

Answers

Answer:

The function is of the form y = a(1 − r)t, where 1 − r < 1, so it represents exponential decay. Use the decay factor 1 − r to find the rate of decay. Write an equation. Solve for r.

The "a" in the expression y = a (1+r)ˣ represents the initial amount.

What is the expression?

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given, a exponential expression  y = a (1+r)ˣ

The exponential growth can alternatively be calculated using the formula f(x) = a(1 + r)ˣ, where the function is denoted by the f(x) term. The initial value of your data is represented by the variable. The growth rate is represented by the r variable.

Therefore, the initial amount is been represented by "a" in the given expression.

The triangles are congruent. Find the measure of x.

Answers

Match up the sides for each triangle using the little marks through the sides

1 to 1, 2 to 2 and 3 to 3

When you do this you see that x corresponds to c on the first triangle.

The 3 angles in a triangle = 180.

Find c by subtracting A and B from 180

C = 180- 29-63 = 88

Now x = c so x = 88

The answer is C. 88
