Smiths bakery is baking several large cakes for a community festival. The cakes consist of two geometrically similar shapes as s
Studentka2010 [4]

Answer:

Approximately 313 cakes of similar size as those 50 cut from the smaller cake, can be cut from the bigger cake.

Step-by-step explanation:

The complete question is with the missing image of the cakes is attached to this solution.

From the image provided, the dimensions of the smaller cake = 2 ft × 1.6 ft

The dimensions of the larger cake = 5 ft × 4 ft

50 cakes are obtained from the smaller cake, how many cakes can be obtained from the bigger cake?

Area of the smaller cake = 2 × 1.6 = 3.2 ft²

Area of the bigger cake = 5 × 4 = 20 ft²

3.2 ft² cake provides 50 cakes.

20 ft² cake will provide (20×50/3.2) cakes = 312.5 cakes

Rounded to the nearest piece of cake = 313 cakes

Hope this Helps!!!

In a circuit, two resistors of 100 Ω and 80 Ω are connected in parallel. The parallel group is then connected in series with a 1
nordsb [41]

Answer:

Total Resistance = \frac{1300}{9} Ω  (or 144.44 Ω)

Step-by-step explanation:

If two resistors, with resistance x and y, are connected in parallel, their total resistance is given by the formula:

\frac{1}{Total}=\frac{1}{x}+\frac{1}{y}

If 2 resistors with resistance x and y and connected in series, their total resistance would be:

Total = x + y

<em>Now, the first part, 100 and 80 are in parallel, so according to formula it would be:</em>

<em>\frac{1}{Total}=\frac{1}{x}+\frac{1}{y}\\\frac{1}{Total}=\frac{1}{100}+\frac{1}{80}\\\frac{1}{Total}=\frac{9}{400}\\Total = \frac{400}{9}</em>

<em />

<em>Now, this is connected in series with 100, so the grand total would be:</em>

<em>Total Resistance of Circuit = \frac{400}{9}+100=\frac{1300}{9}</em>

<em />

This is the total resistance of the circuit.
