ANSWER

Yes, the two expressions are equivalent.

The identity property of multiplication.

EXPLANATION

The identity element for multiplication of real numbers is 1.

This means that, if you multiply any real number by 1, you get the same real number

The given expression is,

$18 \times 1 = 18$

In trigonometry, the right triangle is considered a special triangle because there are derived equations solely for this type. It is really convenient when dealing right triangle problems because it is more simplified courtesy of the Pythagorean theorems. It is derived that the square of the hypotenuse (longest side of the triangle) is equal to the sum of the squares of the other two legs. In equation, that would be c² = a² + b². For this activity, all you have to do is find the sum of the squares in columns a and b. Then, see if this is equal to the square of the values in column c. Let's calculate each row:

Row 1:
3² + 4² ? 5²
25 ? 25
25 = 25

Row 2:
5² + 12² ? 13²
169 ? 169
169 = 169

Row 3:
9² + 12² ? 15²
225 ? 225
225 = 225

Therefore, all of the given values conform to a² + b² = c².

Suppose 6 pints of a 28% alcohol solution is mixed with 4 pints of a 90% alcohol solution. What is the concentration of alcohol

Lisa [10]

Answer:

52.8%

Step-by-step explanation:

The amount of alcohol is:

0.28 (6 pints) + 0.90 (4 pints) = 5.28 pints

So the concentration is:

5.28 pints / 10 pints × 100% = 52.8%.

A local hamburger shop sold a combined total of 380 hamburgers and cheeseburgers on Friday. There were 70 fewer cheeseburgers so

NISA [10]

c= cheesebuger

h= hamburger

h=c+70

c+h=380

c+c+70=380

2c+70=380

2c=310

c=150

h =c+70

h=230
