GIVING BRAINLIEST. David's phone bill each month is $30. He is also charged $0.10 per GB of data he uses. If his phone bill in July was $42, how many GB of data did he use in July? I also need an equation representing the problem.

one set of data has more variation than the other. hope this !

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a

i think its doubled. let me know
