Answer:

a) $49.48

b) $220921.91

Step-by-step explanation:

(a) 4 yd @ $12.37 per yd = 4 x $12.37 = $49.48

(b) 271 yd @ 815.21 per yd = 271 x $815.21 = $220921.91

(c) 20% yd @ $4.95 per yd : Here the nunber of yards are missing. Hence could not be answer . However if number of yards is x . The answer would be

20% of 4.95x

(20%=0.20)

0.20 × 4.95x

Find the constant of proportionality for the table of values and write in the form y = kx

sveta [45]

Answer:

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Number of lemons used is denoted by 'y'.

Number of glasses of lemonade is denoted by 'x'.

As we can observe that ,

$\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\$

so we can write i as

$\frac{x}{y} = \frac{1}{4}$

By cross multiplication

y=4x

So, if write it in the form y=kx,

It will be y=4x.

P(x) = 3x + 4 q(x) = 2x2 Find q(P(x))

max2010maxim [7]

Answer:

Step-by-step explanation:

If we are to find q(p(x)), we are to start at the innermost part of the problem which is p(x). Take the function p(x) and fill it into q(x) every place you see an x:

$2(3x+4)^2$ is the composition of p into q. Now all we have left to do is simplify.

$(3x+4)^2=9x^2+24x+16$

Then we have to finally multiply in the 2 to get:

$18x^2+48x+32$

108x25^2divided by 2^6 x 5^2

My name is Ann [436]

Answer:

108 x 25² divided by 2⁶ x 5² is equal to $42\frac{3}{16}$

Step-by-step explanation:

Given;

108 x 25² divided by 2⁶ x 5²

The expression is simplified as follows;

$\frac{108\times 25^2}{2^6 \times 5^2} = \frac{108\times 625}{64\times25} =\frac{675}{16} = 42\frac{3}{16}$

Therefore, 108 x 25² divided by 2⁶ x 5² is equal to $42\frac{3}{16}$
