Answer: Number of gallons of sulfuric acid is 45 gallons.

Step-by-step explanation:

Since we have given that

Total number of gallons of solution in a tank = 90 gallons

Percentage of sulfuric acid = 50%

We need to find the number of gallons of sulfuric acid;

Number of gallons of sulfuric acid is give by

\frac{50}{100}\times 90\\\\=0.5\times 90\\\\=45\ gallons

Hence, number of gallons of sulfuric acid is 45 gallons.

Explain why functions with the property f(–x) = –f(x) are called odd functions and functions with the property f(–x) = f(x) are
anastassius [24]

Answer:

The functions with the property f(–x) =f(x) are called even functions because they symmetric about the y-axis and The functions with the property f(–x) = -f(x) are called odd because these function are symmetric about the origin .

Step-by-step explanation:

The functions with the property f(–x) =f(x) are called even functions because they symmetric about the y-axis . In other words these functions usually take a form x^2 ,x^4 ,x^6 ,x^8 etc . However ,there are other functions that behave like that too, such as cos(x).An even exponent does not always make an even function, for example (x+1)^2 is not an even function .

The functions with the property f(–x) = -f(x) are called odd because these function are symmetric about the origin . In other words they are called odd because of the functions like x, x^3 ,x^5 ,x^7, etc .but there are other functions that behave like that, too, such sin(x) .but an odd exponent does not always make an odd function, for example x3+1 is not an odd function.

postnew [5]

Answer:

Yes

I hope this answers your question!

Step-by-step explanation:

How do you estimate a division problem?

You can use multiplication to check your division answer this way.

1) Do the division problem.

2) Multiply the quotient times the divisor.

3) If there is a remainder, add it to the multiplication product.

4) Compare this answer to the dividend. They should be the same number (630 = 630).

kogti [31]

Answer:

question 1)   3/5  

question 2)  15  x square root of 2 (around  21.2 cm)

Step-by-step explanation

 The word "Restaurant" contains a total of 10 letters( 4  are vowels and 6 are consonants)

Probability formula is the ratio of number of favorable outcomes to the total number of possible outcomes.

number of favorable outcomes =6

total  number of possible outcome.=10

P=6/10  =  3/5

15  x square root of 2 (around  21.2 cm)

folding diagonally  the square sheet  form a right triangle

In a  right   triangle, the length of the hypotenuse is    the square root of 2   multiplied  by the length of a leg.
