Answer:

The answers would be

1. C

2. B

3. A

Step-by-step explanation:

The term product refers to multiplication. So in question 1, when we see the term quotient, we are looking to multiply.

The term quotient refers to division. So in questions 2 and 3, when we see this term, we look to divide.

Answer:

C. $6n$

B. $\frac{6}{(x+y)}$

A. $\frac{Z}{3}$

Step-by-step explanation:

1. This expression refers to the product operation between real numbers, therefore the correct algebraic form is $6n$

2. This expression refers to the operation division between real numbers, therefore the correct algebraic form is $\frac{6}{(x+y)}$

3. This expression refers to the operation division between real numbers, therefore the correct algebraic form is $\frac{Z}{3}$

Please help me, I don't know how to do this...

Lunna [17]

Answer:

A. 5

Step-by-step explanation:

The triangle will be a right triangle when the side lengths satisfy the Pythagorean theorem: the sum of the squares of the legs is equal to the square of the hypotenuse.

(x +1)^2 +x^2 = (√61)^2

x^2 +2x +1 +x^2 = 61 . . . eliminate parentheses

2x^2 +2x = 60 . . . . . . .subtract 1, collect terms

x^2 +x -30 = 0 . . . . . divide by 2, subtract 30

(x +6)(x -5) = 0 . . . . factor the quadratic

x = -6 or +5

The solution is x = 5.

_____

Side lengths cannot be negative. Solution values are values of x that make the factors zero. x+6=0 when x=-6, for example.

A round wading pool has a diameter of 115cm deep. A hose is filling the pool at a rate of 34000cm^3, cubed per minute. How long

inn [45]

Answer:

It will take 6.118 minutes to fill up the pool to a depth of 20 cm

Step-by-step explanation:

The first step is to calculate the volume of the wading pool.

we will assume it is a cylinder, hence the volume will be = $\pi r^{2}h$

Where r= radius of the pool = 115/2 = 57.5cm

h = depth of the pool =20 cm

The volume of the pool will be $\pi \times57.5^{2} \times 20 =2.08 \times 10^{5} cm ^{3}$

We are filling a pool of 208,000cm ^{3} at the rate of 34000cm^3, cubed per minute.

To get the time it will take to fill up the pool, we will have to divide as follows:

208,000cm ^{3} / 34000cm^3 =6.118 minutes

Therefore it will take 6.118 minutes to fill up the pool to a depth of 20 cm
