Ella wants to estimate the product (3.6)(7.8). Which expression shows each factor rounded to the nearest whole number? (3)(7) (4)(8) (3)(8) (4)(7)

answer: check all that apply, where the options?

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
