A rectangular room is 1.2 1.2 times as long as it is wide, and its perimeter is 35 35 meters. Find the dimension of the room.

Westkost [7]

Answer:

I. Length, L = 9.552 meters

II. Width, W = 7.96 meters

Step-by-step explanation:

Let the length = L

Let the width = W

Given the following data;

Perimeter = 35 m

Translating the word problem into an algebraic equation, we have;

Length = 1.2W

To find the dimension of the room;

The perimeter of a rectangle is given by the formula;

P = 2(L + W)

Substituting into the formula, we have;

35 = 2(1.2W + W)

35 = 2(2.2W)

35 = 4.4W

Width, W = 7.96 meters

Next, we would find the length of the rectangle;

L = 1.2*W

L = 1.2 * 7.96

Length, L = 9.552 meters

Please help!! ASAP

Kryger [21]

Answer:

The answer is 117.3 $in^{3}$ .

Step-by-step explanation:

To solve for the volume of the cone, use the cone volume formula, which is V = $\frac{1}{3} \pi r^{2} h$ .

Next, plug in the information given from the problem, and the formula will look like V = $\frac{1}{3} (\pi) (4 in^{2}) (7 in)$ .

Then, solve the equation, and the answer will be 117.3 $in^{3}$ .

What are the zeros in the function

Schach [20]

$f(x)=x^3+x^2-6x\\\\text{The zeros:}\\\\f(x)=0\to x^3+x^2-6x=0\\\\x(x^2+x-6)=0\\\\x(x^2+3x-2x-6)=0\\\\x[x(x+3)-2(x+3)]=0\\\\x(x+3)(x-2)=0\iff x=0\ \vee\ x+3=0\ \vee\ x-2=0\\\\x=0\ \vee\ x=-3\ \vee\ x=2$

Sara sells homemade blueberry jelly (b) and strawberry jam (s) at the farmer's market. It is the end of berry picking season, so

Diano4ka-milaya [45]

System of inequalities representing given scenario is as follows

x + y ≤40

5x + 4y ≥ 120

<h3>Solution:</h3>

Given that Sara sells homemade blueberry jelly (b) and strawberry jam (s) at the farmer's market. She has enough berries for no more than 40 jars.

The blueberry jelly sells for $5 per jar,

And the strawberry jam sells for $4 per jar.

Sara's goal is to make at least $120

Need to write system of inequalities for above scenario.

Let’s assume number of jars of blueberry jelly be represented by variable “x”

And assume number of jars of strawberry jam be represented by variable “y”

Let’s create first inequality

As it is given that Sara has enough berries for no more than 40 jars, so total number of jars cannot be more than 40.

=> Number jars of blueberry jelly + number of jars of strawberry jam ≤40

=> x + y ≤ 40 ------(1)

Now let’s create second inequality

Selling Price of 1 blueberry jelly = $5

So Selling Price of "x" blueberry jelly $=x \times 5=5 x$

Selling Price of 1 strawberry jam = $4

So Selling Price of "y" strawberry jam = $\$ 4 \times \mathrm{y}=4 y$

So amount generated by selling x blueberry jelly and y strawberry jam = 5x + 4y

And as Sara’s goal is to generate at least $120, so amount generated by selling “x” blueberry jelly and “y” strawberry jam must be greater than $120

=> 5x + 4y ≥ 120 ------ (2)

Hence system of inequalities representing given scenario is as follows :

x + y ≤40

5x + 4y ≥ 120
