Answer:

a) total cost of downloading B is £11.90

b) total cost of downloading B is £12.04

see if that looks right lol

Step-by-step explanation:

a) £9.35 = 935p

935÷11=85p (cost per track)

85 x 14 = 1190p

1190p = £11.90

b) 85 x 6 = 510p

7 x 6 = 42p

510 - 42 = 468p

85 x 8 = 680p

7 x 8 = 56

680 + 56 = 736p

468 + 736 = 1204p

1204p = £12.04

WILL REWARD BRAINIEST! What is the volume of the composite figure if both the height and the diameter of the cylinder are 10.5 f

Mashutka [201]

Answer:

908.74

Step-by-step explanation:

The formula for the volume of a cylinder is V = h * pi * r^2

h is height, r is radius, and pi is 3.14. The radius is half of the diameter, so that would make the radius 5.25.

So now plug it into the formula:

V = 10.5 * pi * (5.25)^2

= 908.74

Hope this helped! :)

Need help quick simplify the expression (-4) power of 3

dezoksy [38]

Answer:

-64

Step-by-step explanation:

The question is asking to solve $(-4)^3$

Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.

$(-4)^3$ is the same as -4 · -4 · -4

First let's figure out if this will be negative or positive

Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive

Now find out what 4 x 4 x 4 equals (64)

In conclusion the answer is -64
