Answer:

The expression of the area as a monomial is 18c^7d^9

Step-by-step explanation:

In algebra, when we talk about the term monomial, we are simply referring to an algebraic expression that contains only a single term.

Now in this question, we have the value of the length and the width but we are interested in turning them to a monomial which is a single term.

Mathematically, the area of rectangle can be calculated using the formula L * W , where l is the length and w is the width.

Thus, we have ;

2c^3d^2 * 9d^7

= 18c^7d^(2+7)

= 18c^7d^9

Cammie can mow 1/2 acre in 25 minutes. If her rate is constant, Cammie says she can mow 1 1/4 acres in one hour. Is Cammie corre

Sergeu [11.5K]

Answer: No, Cammie is not correct. She can mow $1\frac{1}{5}\ acres$ in one hour (See explanation).

Step-by-step explanation:

Convert the mixed number to an impoper fraction:

1. Multiply the whole number part by the denominator of the fraction and add the product to the numerator.

2. The denominator does not change.

Then:

$1\frac{1}{4}=\frac{(1*4)+1}{4}=\frac{5}{4}$

Let be "x" the acres Cammie can mow in one hour.

You know that she can mow $\frac{1}{2}\ acre$ in 25 minutes, then you can set up the following proportion (Remember that 1 hour has 60 minutes):

$\frac{\frac{1}{2}}{25}=\frac{x}{60}$

Solving for "x", you get:

$\frac{\frac{1}{2}}{25}=\frac{x}{60}\\\\(60)(\frac{1}{50})=x\\\\x=\frac{6}{5}$

Convert from improper fraction to mixed number:

1. When you divide 6 by 5, the quotient is 1. This will be the whole number part.

2. The remainder is 1. This will be the numerator.

3. The denominator does not change.

Then:

$x=1\frac{1}{5}$

Therefore, she can mow $1\frac{1}{5}\ acres$ in one hour.

The value of y varies directly as x and y is 9 when x is -3 what constant of variation k?

Lady bird [3.3K]

Y/x=k

when y=9, then x= -3
9/-3=-3
⇒ k= -3
