Carolyn is using the table to find 360% of 15. What values do X and Y represent in her table?

Ganezh [65]

★ 100% of 15 = X

$\implies \mathsf{100\%\;of\;15 = \left(\dfrac{100}{100} \times 15\right) = 15}$

$\implies \mathsf{X = 15}$

★ 20% of 15 = Y

$\implies \mathsf{20\%\;of\;15 = \left(\dfrac{20}{100} \times 15\right)}$

$\implies \mathsf{20\%\;of\;15 = 3}$

$\implies \mathsf{Y = 3}$

<u>Answers</u> : X = 15 and Y = 3

You need 3 sticks of butter for every 24 giant cookies you bake.

marta [7]

Answer:

Sticks of butter : 2

Number of cookies : 40

Step-by-step explanation:

<em>Given that :You need 3 sticks of butter for every 24 giant cookies you bake.</em>

<em>----------------------------------------------------------------------------------------------------------</em>

<em>Sticks of butter Number of cookies</em>

<em> 3 24</em>

<em> x 16</em>

<em>5 y</em>

<em>----------------------------------------------------------------------------------------------------------</em>

<em>Let the unknown be x and y..</em>

<em>Since you need 3 sticks of butter for every 24 giant cookies you back</em>

<em>Then 24/3 = 8</em>

<em>Since the number of cookies is 16 then 16/8 = 2</em>

<em>Thus x = 2</em>

<em>Next for y.</em>

<em>Since you need 3 sticks of butter for every 24 giant cookies you back</em>

<em>Then 5 * 8 = 40</em>

<em>Thus, y = 40</em>

<em>----------------------------------------------------------------------------------------------------------</em>

<em>Completed table below:</em>

<em>Sticks of butter Number of cookies</em>

<em> 3 24</em>

2 <em> 16</em>

<em>5 </em><em>40</em>

<em>----------------------------------------------------------------------------------------------------------</em>

What is the answer to this somebody!!!

Fed [463]

Use the geometric mean for right triangles as the sides are related to the hypotenuse. 30 - 6 = 24. We need that for our proportion. $\frac{24}{x}=\frac{x}{30}$ . We cross-multiply to get $x^2=720$ . Taking the square root of both sides gives us that $x=12\sqrt{5}$ , the second choice above.
