Answer:

£1.31

Step-by-step explanation:

5:7:12

  • 5x+7x+12x= 216
  • 24x= 216
  • x= 9

small : medim : large = 45 : 63 : 108

  • 45y+63*2y+108*3y= 648.45
  • y(45+126+324)= 648.45
  • 495y= 648.45
  • y= 648.45/495
  • y= £1.31 profit for small cake

Answer:

£1.31

Step-by-step explanation:

The cakes are sold in the ratio 5 : 7 : 12 = 5x : 7x : 12x ( x is a multiplier )

sum the parts of the ratio, 5x + 7x + 12x = 24x

Equate 24x to the number of cakes sold, that is

24x = 216 ( divide both sides by 24 )

x = 9

Thus cakes sold are

5x = 5 × 9 = 45 small cakes

7x = 7 × 9 = 63 medium cakes

12x = 12 × 9 = 108 large cakes

let p represent the profit on a small cake, then

45p + 63(2p) + 108(3p) = 648.45 , that is

45p + 126p + 324p = 648.45

495p = 648.45 ( divide both sides by 495 )

p = 1.31

That is the profit on one small cake is £1.31

Simplify the expression. Write your answer using only positive exponents:7^6 x 7 x 7^-4
svetoff [14.1K]
The problem is asking you to simplify the exponents.  When you multiply two or more powers with the same base, the exponents can be added and subtracted.  In this case, the base is 7.

7^6*7*7^{-4}

7 can also be written as 7^1.

7^6*7^1*7^{-4} = 7 ^{(6+1-4)} = 7^3

The answer would be 7³ if you kept the exponent, or 343 if you simplified further.

In Lesson 3.05 we discussed comparing the key features of two functions given in different forms. Given the functions below:
Nutka1998 [239]

Answer:

A) f(x) has y-intercept at and g(x) has y-intercept at (0,0)

B) f(x) has asymptote as x= 0 and g(x) has asymptote as x= 4.

Step-by-step explanation:

The functions given are f(x)=\frac{1}{x-3} and the graph of g(x).

A): Since, <em>'y-intercepts are the points where the graph of the function cuts y-axis' </em>

<em>So, 'at x=0, we obtain y-intercepts'.</em>

Thus,

f(0)=\frac{1}{0-3} implies f(0)=\frac{-1}{3}

Hence, (0,\frac{-1}{3}) is the y-intercept of f(x).

Now, we see that,  

The graph of the function g(x) crosses y-axis at the point (0,0).

Hence, the (0,0) is the y-intercept of the function g(x).

B): As we know, <em>'asymptotes are the lines that approaches the curves but does not meet them'. </em>

As, the numerator of f(x) is of lower degree than the denominator.

We have, the function f(x) has x= 0 as the horizontal asymptote.

Further, graph of g(x) gives us, 'the line x= 4 is the asymptote'.

Hence, the function g(x) has vertical line x= 4 as the asymptote.
