The polleys want to put in a swimming pool next summer. they need to save $6,000 over 12 months in order to achieve this goal. they set aside the same amount each month and after 7 months discovered they have saved $3,100. the polleys know that they must adjust their plan in order to meet their goal, so they come up with the following options: option a: save the original amount each month but put the pool in one month later than originally planned. option b: increase savings each month by $100 from their original plan. which of the following statements is true?

Therefore Neither option A nor option B will allow them to meet their goal

Step-by-step explanation:

The Polleys need to save $6,000 over 12 months.

After 7 months they discovered that they have saved $ 3,100 but in actual they have to save $3,500. It means $400 are short. Therefore for the remaining months they must save $6000-$3100 = $2900. They have to save 2900/5 = $580 each month.

According to the Option A The original amount was $500, in 5 months they will save 500*5 =$2500. They need total of $2900, which means $400 are short.

According to the Option B  Increase savings each month by $100 from their original plan makes a total amount of $3000. This amount exceeds their goal.

Therefore Neither option A nor option B will allow them to meet their goal

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
