Solution:

we have been given that

James can swim 10 laps in 23 minutes.

we have been asked to find the expected time for 15 laps.

Since James can swim 10 laps in 23 minutes.

It mean that James can swim 1 lap in =\frac{23}{10}=2.3 \ minutes

So for 15 laps expected time will be =\frac{23}{10}*15= 34.5 minutes

10/23=15/m
(15x23)/10
343/10
34.3

so....
10 laps in 23 minutes
=
15 laps in 34.3 minutes

How to solve for x and what does x equal in this?​
Tanya [424]

Answer:

10

Step-by-step explanation:

give brainliest please!

hope this helps :)

so these two angles add up to 180 degrees

7x -3 + 12x -7 = 180

7x+12x=180+7+3

19x=190

x=10

to check if this is true we can input 10 for x in each side.

7(10)-3 = 67

12(10)-7 = 113

113+67 = 180

Say that australia has a working population of 11,565,470 people, and that the average salary is $26,450 annually. how much tax
Archy [21]

The tax revenue Australia would generate each year is $96,054,697,991.

<h3>What is the percentage?</h3>

The percentage is the value per hundred.

Working population of Australia =  11,565,470 people

Annual average salary = $26,450

Income tax rate = 31.4%

Tax revenue generated by each resident = 26450*(31.4/100)

Tax revenue generated by each resident =$8305.3

So, Tax revenue generated by 11,565,470 residents =  11,565,470*8305.3

Tax revenue generated by 11,565,470 residents = $96,054,697,991

Therefore, the tax revenue Australia would generate each year is $96,054,697,991.
