Ava spends about 45 minutes studying each day. She also practices the piano for an average of 20 minutes per day, and she practi
Korolek [52]

Answer:

<h2>398.88hours</h2>

Step-by-step explanation:

Note: If Ava decides to reduce the time she does each activity by 16minute I believe it should be

1. Ava spends 45min per day studying

    reduce this amount be 16min we have=45-16=29min

    in a year she will spend 365*29= 10585min

2. She also practices the piano for an average of 20 minutes per day

   reduce this amount be 16min we have=20-16=4min

    in a year she will spend 365*14= 5110min

3. She practices soccer 1.5 hours three times a week.

   in minutes 1.5hours is 90min three times a week

   in a day 90*3/7= 270/7=38.57

    reduce this amount be 16min we have=38.57-16=22.57min

    in a year she will spend 365*22.57= 8238.05min

in total for the year  she spends studying and practicing

=10585+ 5110+8238.05

=23933.05min to hours =23933.05/60

=398.88hours

Can you please help me before it kicks me out of the session

EXPLANATION

Let's see the facts:

------------------------First triangle ----------------------------

First side measure =3

Second side measure = 4

Included angle measure = 62

----------------------Second triangle ------------------------

First side measure = 27

Second side measure= 36

Included angle measure = 62

We have two included and congruent angles because 62=62.

Let's make a representation:

Now, in order to conclude if both triangles are similar we need to prove that the relationship or ratios between the sides is the same, and then, by the S-A-S Postulates, we could infer that both triangles are similar.

First side relationship: 3/27 = 1/9

Second side relationship: 4/36 = 1/9

1/9 = 1/9

As First side relationship = Second side relationship, then the relationship is the same and by SAS Postulate, the triangles are similar.

Are the triangles similar? Yes, by SAS postulate.

In rectangle JKLM, JK is equal to 10 feet and MN is equal to 25 feet, find JL.
Snezhnost [94]

we know that

if JKLM is a rectangle

then

diagonals

MK=JL

so

MK=2*MN------> MK=2*25 ft------> MK=50 ft

JL=MK----> JL=50 ft


therefore


the answer is

JL is 50 ft
