The total hours for the week is 32 hrs 55 mins.

Mon total hours = ( 12:00 - 8:30) + ( 17:35 - 12: 35)hrs

= 3 hrs 30 mins + 5 hrs

= 8hrs 30mins

Tue total hours = ( 12:15 - 8:25) + ( 17:30 - 13: 00)hrs

= 3hrs 50mins + 4hrs 30mins

= 8hrs 20mins

Wed total hours = ( 12:45- 8:28) + ( 16:25 - 13: 15)hrs

= 4 hrs 17 mins + 3hrs 10 mins

= 7hrs 27mins

Thu total hours = ( 01:08- 8:15) + ( 17:42 - 13: 45)hrs

= 4hrs 53mins + 3hrs 57 mins

=8hrs 50mins

Fri total hours = ( 12:30- 8:50) + ( 17:08 - 13: 00)hrs

=3hrs 40mins + 4hrs 8 mins

Answer:

With a 90 percent confidence interval, you have a 10 percent chance of being wrong.--

Step-by-step explanation:

have a nice night

The rule of the compounded interest is

A is the new value

P is the initial value

r is the rate in decimal

n is the period

t is the time

He invested $2000

P = 2000

The account earns an 8% annual interest

r = 8% = 8/100 = 0.08

The balance is for 4 years

t = 4

For no 1 it is annual, then

n = 1

Substitute these values in the rule above

Round it to the nearest cent means 2 d.p

The balance is $2720.98

2. Semi-annual means

n = 2

So we will substitute n by 2

Round it to the nearest cent

The balance is $2737.14 in semi-annual

3. Quarterly means

n = 4

So we will substitute n by 4

Round it to the nearest cents

The balance is $2745.57 quarterly

4. Monthly means

n = 12

Substitute n by 12

Round it to the nearest cent

The balance is $2751.33 monthly

So first of all we have to solve this equation:

We can perform the operation 94+91=185 so we get:

And we can substract 185 from both sides of the equation:

Then the answer to part a is 215.

Now that we have the number of seats on the stage level we can find the max amount of money the theater can bring in. This will be given by the total number of seats in the stage level multiplied by the cost per ticket for these seats plus the total number of seats in balconies (185) multiplied by the cost per ticket for these seats. Then we get:

Then the max amount of money the theater can bring in for a show and answer to part b is $11075.

If Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, considering the rate of interest to be (R%) per annum, the domain and range for a function modeling the total amount of the investment, including interest are as follows:

Domain [X = {0 ≤ years ≤ 10}]

Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]

As per the question statement, Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, and since there is no information about the rate of interest of that investment, we are considering the rate of interest to be (R%) per annum.

We are required to determine the domain and range for a function modeling the total amount of the investment, including interest using the question statement mentioned data and our assumptions.

Since the starting principal amount, say P is $25,000, given,

Time of investment, say T is 10 years, also given,

And considering the interest rate per year to be R (%),

Then after 10 years, the total amount Vladimir has is [25000( 1 + xR)].

Where, the Domain (No. of years ) is [X = {0 ≤ years ≤ 10}]

And Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]

It's answer is option(C) i.e, 4/15

The average rate of function f  over the interval a≤x≤b is given by ,

(f(b) - f(a)) / (b - a)

It is the average amount by which the function changed per unit throughout that time period.

In this question the equation is given,

g(x) = log2 (x+6)-3

Solve this eq. by putting the values [-5, 10],

let, interval [-5, 10] = [a, b]

Then solve for g(a) and g(b), we know g(a) = g(-5),

g(-5) = log₂(-5+6) - 3

       = log₂1 - 3

       = 0 - 3

g(-5) = -3

Now, for g(b) = g(10)

g(10) = log₂(10+ 6) - 3

        = log₂16 - 3

        = 4 - 3

g(10) = 1

Now put these values in average rate formula,

Average rate = (g(b) - g(a)) / (b - a)

                      = (1 - (-3)) / (10 - (-5))

                      = (1 + 3) / (10 + 5)

                      = 4 / 15

Therefore, the average rate is 4/15 i.e, option(C)

Step-by-step explanation:

The inverse and domain of the inverse of the function are attached below.

In mathematics, an inverse is a function that serves to “undo” another function. That is, if y produces y, then putting y into the inverse of produces the output x.  A function y that has an inverse is called invertible and the inverse is denoted by inverse of y.

Samuel's average speed was 0.26 kilometers per minute during his morning training.

Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.

Given that Samuel was preparing for a triathlon. Every morning, he accomplished three things: I ran for 30 minutes and covered 4.5 miles. I swam for 20 minutes, covering around 2/3 miles. I biked for 45 minutes and 9 kilometers.

Here, we have the total distance traveled by Samuel = 4.5 + 2/3 + 9 = 14.17 kilometers  

And  the total time is taken by Samuel  = 30 + 20 + 45 = 55 minutes

So, the average speed = distance / time

The average speed = 14.17/55

The cost of Brandon's taxi ride is $ 4.8.

A taxi ride in a large city costs $3.50 plus $6 for each mile traveled .The 3 mile cab ride includes a basic charge as well as the cost for the distance covered.If Brandon traveled 7.5 miles by taxi, how much was the cost, C, of his taxi.

For a 6 mile trip, the cost is $4.80 which means that :

The cost of 3 miles is $4.80−$3.00=$1.80

Therefore the cost for 1 mile is $1.80÷3=$0.60

The basic fee for hiring the cab is $3.00−$1.80=$1.20

So the total cost, c for a trip of d miles will be shown below:

Explanation:

5624 is close to 5600

72 is close to 70

Therefore, 5624 ÷ 72 is close to 5600 ÷ 70 = 80

Think of it like saying 56 ÷ 7 = 8 but then we add the zeros onto each to get what is shown above.

--------

Use your calculator to find that

5624 ÷ 72 = 78.111 approximately

which isn't too far from the estimate value of 80. Our estimate is an over-estimate.

Answer: 80

Step-by-step explanation:

First change the equation to the nearest tenth,
5620 divided by 70

Now, break up the 70 into ( 10 * 7 )

So first do 5620 divided by 10

5620 divided by 10 = 562

Now if we round to the nearest tenth again we get 560

Now we can divide 560 by 7

Which comes out to 80

o=day 1. t=day 2. th=day 3

o+t+th=36

o+4=th

64o+62t+58th=2196

(o+t+th=36)*58

58o+58t+58th=2088

64o+62t+58th=2196

-(58o+58t+58th)=2088

6o+4t=108

o+t+th=36

o+t+o+4=36 ==> th=o+4

2o+t+4=36

2o+t=32

(2o+t=32)*3

6o+4t=108

-(6o+3t=96)

t=108-96

Non shadow part (white one) seems to be 1/4 of a circumference

So we need to find area of square minus area of 1/4 of the circumference

Square area = L^2 = 6^2 = 36

Circumference Area = (πr^2)/4 = (π*6^2)/4 = 28.27

Area of the shaded portion = 36 - 28.27 = 7.72

2 - x = - 7

Adding x at both sides of the equal signe, we get:

2 - x + x = - 7 + x

2 = -7 + x

Adding 7 at both sides:

2 + 7 = -7 + x + 7
