The variable y varies directly as x and inversely as z. When x = 4 and z= 14, y=2.
Fudgin [204]

Given:

The variable y varies directly as x and inversely as z. When x = 4 and z= 14, y=2.

To find:

The combined variation equation and find y when x = 6 and z= 3.

Solution:

The variable y varies directly as x and inversely as z.

y\propto \dfrac{x}{z}

y=k\dfrac{x}{z}           ...(i)

Where, k is the constant of proportionality.

Putting x=4, y=2 and z=14, we get

2=k\dfrac{4}{14}

2=k\dfrac{2}{7}

2\times \dfrac{7}{2}=k\dfrac{2}{7}\times \dfrac{7}{2}

7=k

Putting k=7 in (i), we get

y=7\dfrac{x}{z}

Putting x=6 and z=3, we get

y=7\times \dfrac{6}{3}

y=7\times 2

y=14

Therefore, the required equation is y=7\dfrac{x}{z} and the value of y is 14 when x = 6 and z= 3.

Marya wants to factor the polynomial 36x^3 – 22x^2 – 144x. Which term can she add to the polynomial that would not change its gr
Tatiana [17]

Answer:

-50xy

-40x²

Step-by-step explanation:

1. The greatest common of the variable is the variable with the lowest exponent, as you can see, the exponents are: 3,2 and 1. The lowest exponent is 1, then, it is x.

2. The greatest common factor of the coefficients is 2,  because all of them are divisible by 2.

3. Therefore, you can add a term that has the greatest common factor 2x. This means that the term must have the variable "x" and the coefficient must be divisible by 2:

4. The terms -50xy and -40x² has the greatest  common factor 2x.

The sum of the two shorter sides of a triangle must be equal to the longest side to be classified as a triangle
kogti [31]

Answer:

False

Step-by-step explanation:

For example if you follow the pythagoras theorem a triangle has sides of 3,4 and 5

but when you add 3 and 4 they do not give you 5

so that is false

Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?
Roman55 [17]

Answer:

6x - 5 ≥ 8

Step-by-step explanation:

Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?

The inequality sign of

a) At least = greater than or equal to = ≥

Let us represent the number as = x

Hence: "five less than the product of a number and 6 is at least 8" can be written as:

= x × 6 - 5 ≥ 8

= 6x - 5 ≥ 8

Jenna sells apples and pears. If 20 apples and 60 pears re sold every hour, there will be 80 pears when all the apples are sold.
lutik1710 [3]

Answer:

There are 1,360 pears.

Step-by-step explanation:

Suppose that there are P pears and A apples.

We know that:

"If 20 apples and 60 pears are sold every hour, there will be 80 pears when all the apples are sold."

Suppose that all of these are sold after N hours, then:

20*N = A

80*N = P - 80

We also know that:

"if 60 apples and 20 pears are sold every hour, there will be 400 pears when all the apples are sold."

60*N = A

20*N = P - 400

Then we have four equations:

20*N = A

80*N = P - 80

60*N = A

20*N = P - 400

From the first one and the second one, we get:

20*N = A = 20*N = P - 400

A = P - 400

Now we have 3 equations:

80*N = P - 80

60*N = A

A = P - 400

Now we can just replace the third equation into the second one, then we get:

60*N = A = P - 400

Now we have two equations:

80*N = P - 80

60*N = P - 400

Now, remember that we want to find the number of pears, so we want to find the value of P.

To do it, we can take the quotient of the two equations, so we get:

(80*N)/(60*N) = (P - 80)/(P - 400)

8/6 = (P - 80)/(P - 400)

Now we can solve this for P

(8/6)*(P - 400) = P - 80

(8/6)*P - (8/6)*400 = P - 80

(8/6)*P - P = (8/6)*400 - 80

(2/6)*P = (8/6)*400 - 80

P = (6/2)*( (8/6)*400 - 80 )

P = 3*( (8/6)*400 - 80 ) = 1,360

There are 1,360 pears.
