Answer:

The highway fence cost $600.

Step-by-step explanation:

Since the highway fence is twice as cost as the one of the other 4 sides, this means that the highway fence = 2 normal fence.

Therefore, we use

$1800 / highway fence(2 normal fence) + 4 normal fence

$1800 / (2 + 4) = $300

This means that every normal fence cost $300.

Which then we get the highway fence is $600 because it costs double of the normal fence.

Answer:

$A_{2} = 720\ ft^{2}$

Step-by-step explanation:

Let w and l be the width and length of the garage.

Let $A_{1}$ and $A_{2}$ be the area of garage at present and new garage.

Given:

The area of the garage at present

$A_{1}=80\ ft^{2}$

And he planed to tripling the dimensions of the garage.

We need to find the area of the new garage.

Solution:

We know the area of the rectangular garage.

$Area=width\times lendth$

$A_{1}=w\times l$

$w\times l=80$ ---------------(1)

The dimension of the new garage is triple, so the area of the new garage is.

$A_{2} = (3\times width)\times (3\times length)$

$A_{2} = (3\times w)\times (3\times l)$

$A_{2} = 9\times (w\times l)$

Substitute $w\times l=80$ from equation 1.

$A_{2} = 9\times (80)$

$A_{2} = 720\ ft^{2}$

Therefore, the area of the new garage $A_{2} = 720\ ft^{2}$

Proportionately, the amount of the drug that the patient should be given is <u>2,993.71 mg</u>.

<h3>What is the proportion?</h3>

The proportion is the ratio of a variable to another.

Proportion defines the numerical relationships among variables.

Proportion shows how much a value is contained in the whole.

<h3>Data and Calculations:</h3>

2.20462 lb = 1 kg

165 lb = 74.8428 kg (165/2.20462)

1 kg = 40 mg of the drug

74.8428 kg = 2,993.71 mg (74.8428 kg x 40 mg)

Thus, the amount of the drug that the patient should be given is <u>2,993.71 mg</u>.

X=32 because both equations are equal to 180 degrees (3x+22°+x+30°=180) just solve that equation and you’ll get your answer
