By taking the average of her balance of each day of August, we will see that the average daily balance is $373.08

We know that:

So, first, her balance is $579.53 for 7 days. Then her balance is $79.53 for 8 days, then her balance was $279.53 for another 8 days, and finally, her balance was $579.53 for the last 8 days of august.

Then over the 31 days of August, the average daily balance will be:

[tex]A = \frac{7*579.53 + 8*79.53 + 8*279.53 + 8*579.53}{31} = 373.08[/tex]

So in August, her average daily balance was $373.08

The volume of the films is the amount  of film in the case

The cost of the films is $810.41

The given paramerers are:

The mass of the films is calculated as:

Mass = Density * Volume

This gives

Mass = 7.6 * 965 g

Evaluate

Mass = 7334 g

Express as kg

Mass = 7.334 kg

The unit cost is:

Unit cost =  $0.34 per kilogram

The number of films is

n = 325

So, the total cost

Total = 325 * 0.34 * 7.334

Evaluate

Total = 810.41

Hence, the cost of the films is $810.41

Answer:

arc AD = 126°

Step-by-step explanation:

the inscribed angles ABD and ACD are half the measure of their intercepted arc AD

then ∠ ABD and ∠ ACD are congruent , so

11x - 3 = 8x + 15 ( subtract 8x from both sides )

3x - 3 = 15 ( add 3 to both sides )

3x = 18 ( divide both sides by 3 )

x = 6

then

∠ ABD = 11x - 3 = 11(6) - 3 = 66 - 3 = 63° , thus

arc AD = 2 × 63° = 126°

6

Step-by-step explanation:

If you draw out a number line, and a little tick for each number, X will be on the 11 mark (I'll try to do a little thing here)

1  2  3  4  5  6  7  8  9  10  11  12  13  14  15  16

The 11 is where X is

The question says that point Y is 5 LESS than point X, so we want to go down 5 numbers.

1  2  3  4  5  6  7  8  9  10  11  12  13  14  15  16f

(6 is 5 less than 11)

So the point Y will be on the 6

Step-by-step explanation:

x - 16 < 43

there are many values that can make it true

pretty much any number that can have 16 subtracted from it and be less than 43 will work.

or any number less than or equal to 43.

for example:

34-16<43

18 < 43

Answer:

  A: geometric; 4 times

  B: arithmetic: 4 more

Step-by-step explanation:

An arithmetic model is a linear model, where the rate of change is constant.  Growth or decay is by a constant amount from one interval to the next.

A geometric model is an exponential model, in which the rate of change is proportional to the amount. Growth or decay is by a constant factor from one interval to the next.

__

The equation for the sequence is given in "explicit" form:

  [tex]A_n=2^{2n}[/tex]

The exponent can be split so this can be rewritten as ...

  [tex]A_n=(2^2)^n=4^n[/tex]

If this were written in recursive form, it would look like ...

  [tex]A_0=1,\ A_n=4\times A_{n-1}[/tex]

The fact that terms are related by a constant factor tells you the model is geometric. The factor tells you each hour the population is 4 times what it was in the previous hour.

__

The given equation is in "recursive" form. It tells you each term is 4 more than the previous one. This constant difference between terms means the model is arithmetic.

The total purchase price of the car including tax, license, and title $27,722.01.

The purchase price of a car is $25,625 the credit union requires a 10% down payment and an annual interest 9% loan for 36 months. The sales tax is given 7.5%, and the license and title charges are $175.13.

The total sale is the product of the selling price and one plus the sales tax rates.

Total sale = selling price × (1 + sales tax rate)

The price of the car including tax

= $25,625 × (1 +7.5%)

= $27,546.88

By adding license and title charges to the amount, we get

= $27,546.88 +175.13

= $27,722.01

Hence, The total purchase price of the car including tax, license, and title $27,722.01.

1 1/2 hours = 90 mins

add all these:

110

90

85

55

35

when you add all these you get 375

every hour has 60 minutes

375 ÷ 60 = 6.15

if he starts at 9 am and he cleans for 6.15 hours he will be finished by 3:15pm.

Based on the number of minutes Theo will take to clean the various rooms, and the time he will take to rest, he will finish cleaning at 3:15 pm.

The best thing to do here is to convert all the minutes to decimals. This would make adding them up easier.

Kitchen = 1 hour 50 minutes = 1 + 50/60 = 1.833 hours

Lounge = 55 minutes = 55/60 = 0.916 hours

Bedroom = 1.5 hours

Bathroom = 35 minutes = 35/60 = 0.583

Breaks = 85 / 60 = 1.417

Add them up:
= 1.833 + 0.916 + 1.5 + 0.583 + 1.417

= 6.249 hours

= 6 + (0.249 x 60 minutes)

= 6 hours 15 minutes

The time he will finish is:

= 6 hours 15 + 9

= 1515 hours

The number of dolls Jacky is 50 and the number of dolls Peter is 20. Then the total number of dolls is 70.

A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.

The ratio of the number of dolls Jacky had to the number of dolls Peter had was 5: 2.

[tex]\rm \dfrac{x}{y}=\dfrac{5}{2}[/tex]

Let the number of dolls Jacky be x and the number of dolls Peter be y.

But, after Jacky gave 15 dolls to Peter, they have an equal number of dolls. Then we have

x - 15 = y + 15

     x = y + 30

Then we have

[tex]\begin{aligned} \rm \dfrac{y+30}{y} &=\dfrac{5}{2}\\\\2y + 60 &= 5y \\\\3y &= 60 \\\\y &= 20 \end{aligned}[/tex]

Then x will be

x = y + 30

x = 20 + 30

x = 50

Then the total number of dolls they have altogether will be 70.
