Answer:

1. 8/$12=21/$x then cross multiply.

2. 1/$1.5, we're looking for cost so $1 is more reasonable

3. $31.5

Step-by-step explanation:

12x 21/ 8 = 31.5

Answer:

<h2>$31.50 </h2>

Step-by-step explanation:

To solve this problem, we need to use the rule of three, which is based on ratios and proportional relationships.

The ratio that shows the cost of pasta is:

\frac{\$12}{8 lb}

Which means that they charge $12 per 8 pounds of pasta.

Now, it would be help if we use the given ratio to apply the rule of three. Looking for a ratio per pound of pasta would be waste of time, and could confuse a lot. So, we just use the given ratio.

If 8 pounds of pasta costs $12, how much would be 21 pounds of pasta?

x=21 \ lb\frac{\$12}{8 \ lb}=\$ 31.50

Therefore, according to the given ration, it would cost $31.50 to get 21 pounds of pasta.

You are standing at point C, 45 feet from the Point State Park fountain in Pittsburgh, PA. The distance from you to a point of t
bearhunter [10]

The tangent line DC is perpendicular to the radius of the park

The length of AC is 245 feet

<h3>How to determine the distance AC?</h3>

To calculate the distance AC, we start by calculating the length of AB using:

DC^2 = (BC + AB) * BC

So, we have:

105^2 = (45 + AB) * 45

Evaluate the exponent

11025 = (45 + AB) * 45

Divide both sides by 45

245 = 45 + AB

Rewrite as:

AB + 45 = 245

From the figure, we have:

AC = AB + 45

Substitute AB + 45 = 245

AC = 245

Hence, the length of AC is 245 feet

Pat shows that 16 1/2= the square root of 16. What is one possible way pat could have shown this correctly?
kifflom [539]
<h3>Answer: Choice C</h3>

The base 16 is the same as 4*4.

From there, the rule (a*b)^c = a^c*b^c is used to get (4*4)^{1/2} = 4^{1/2}*4^{1/2}

Afterward, the exponents are added getting 1/2+1/2 = 2/2 = 1. The rule is a^b*a^c = a^{b+c} which only works if the bases are both the same.
