3. (A) Ysabel's family has completed 50% of a trip. They have traveled 15 miles. How far is the tripi?
a. 25 miles
b. 15 miles
C. 30 miles
(Please explain!) :)
d. 100 miles

C. 30 miles

Step-by-step explanation:

15 miles = 50%

30 miles = 100%

Why the answer is C is because half of the distance of the road trip is 15 miles, and to find how far the distance of the trip is you add 15 miles and 15 miles because a half and a half is equal to a whole. And 15 miles is half of the road trip distance.

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

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
