Barb’s Grandma is always creating math problems for her to solve. In one problem she gave Barb a store receipt that listed 72 identical items, each the same price, for a total cost of $*67.9* Barb’s grandma covered the first and last digits of the total price on the receipt with stars. Determine the value of the digits that Barb’s Grandma covered.

Answers

Answer 1

9514 1404 393

Answer:

  367.92

Step-by-step explanation:

72 = 9·8

In order for the total cost to be divisible by both 8 and 9, it must meet a couple of requirements:

The sum of the digits must be divisible by 9. The last three digits must be divisible by 8.

In order for the sum of digits to be divisible by 9, the first and last digits must total 5 or 14. (The total of existing digits is 22. The sum needs to be 27 or 36.)

In order for the last three digits to be divisible by 8, the last digit must be 2*. So, the first digit must be 5-2=3.

The first digit is 3; the last digit is 2.

The total cost is 367.92. Each item price is 367.92/72 = $5.11.

_____

* 790/8 = 98.75, so (790 + 2)/8 will be 99. 792 is the only number starting with 79 that is divisible by 8.

1. How many numbers less than 10,000 are there which are divisible
by 21, 35 and 63?​

Answers

Answer:

31

Step-by-step explanation:

To solve this problem, we must find the lowest common multiple of 21, 35 and 63

   Find the prime factors of the number;

 Prime factors of 21  = 3 x 7

                            35 = 3 x 5

                            63 = 3 x 3 x 7

  The lcm = 3 x 3 x 5 x 7 = 315

The numbers between  1 and 10, 000 divided by these three numbers;

   First number  = 315

    Last number  = 9765

Now the total number:

      = [tex]\frac{first number - last number }{315} + 1[/tex]

      = [tex]\frac{9765 - 315}{315}[/tex] + 1

     = 30 + 1

     = 31

Use technology to solve the following problem: The lifetime of a certain type of automobile tire (in thousands of miles) is normally distributed with mean μ = 38 and standard deviation σ = 7. What proportion of tires have lifetimes between 36 and 46 thousand miles?

Answers

Answer:

0.4859

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score,

μ is the population mean, and

σ is the population standard deviation.

From the question:

mean μ = 38,000

standard deviation σ = 7,000

For.

36 ( thousand miles) = 36,000

z = (x-μ)/σ

z = 36,000 - 38,000/7000

z = -0.28571

Probability value from Z-Table:

P(x = 36000) = 0.38755

For 46 thousand miles = 46,000

z = (x-μ)/σ

z = 46,000 - 38,000/7000

z =1.14286

Probability value from Z-Table:

P(x = 46000) = 0.87345

The proportion of tires that have lifetimes between 36 and 46 thousand miles is calculated as:

P(x = 46000) - P(x = 36000)

0.87345 - 0.38755

= 0.4859

You can afford a $1350 per month mortgage payment. You’ve found a 30 year loan at 7% interest.

A) How big of a loan can you afford?

B) How much total money will you pay the loan company?

C) How much of that money is interest?

Answers

A) 45 because 1350 divide by 30 equals 45. So 45 dollars u can afford

B) 1350 because 45 x 30 = 1350


C) 7% because it’s 7% to begin with

A) The loan amount you can afford is, $177,690.52

B) There will be paid a total of $486,000 to the loan company over the course of 30 years.

C) $308,309.48 of the total money you will pay the loan company is interest.

Given that,

You can afford a $1350 per month mortgage payment.

And, found a 30-year loan at 7% interest.

A) Using the formula for calculating the monthly mortgage payment, we can rearrange it to solve for the loan amount:

Loan Amount = [tex]\frac{Monthly Payment }{(Monthly Payment * (1 + (\frac{1}{1+Monthly Payment )^{Number of payments} } }[/tex]

Plugging in the given values:

Monthly Payment = $1350

Monthly Interest = 7% / 12

= 0.00583

Number of Payments = 30 years × 12 months

= 360

Hence,

Loan Amount = [tex]\frac{1350}{(0.00583 (1 + \frac{1}{1+ 0.00583)^{360} } )}[/tex]

By evaluating this expression,

the loan amount you can afford is,

$177,690.52

B) The total money you will pay the loan company,

Total Money Paid = Monthly Payment × Number of Payments

Total Money Paid = $1350 × 360

= $486,000

Therefore, you will pay a total of $486,000 to the loan company over the course of 30 years.

C) the amount of money which is interest,

Interest Paid = Total Money Paid - Loan Amount

Interest Paid = $486,000 - $177,690.52

= $308,309.48

Hence, $308,309.48 of the total money you will pay the loan company is interest.

How much money will it cost to buy the paint? Show all work

Answers

Answer:

Step-by-step explanation:

Circle:

diameter = 30 ft

r = 30/2 = 15 ft

Area = πr²

         = 3.14 * 15*15

         = 706.50 square feet

Triangle:

base (b) = 30 ft

height (h) = 20 ft

Area = [tex]\frac{1}{2}bh[/tex]

        [tex]=\frac{1}{2}*30*20\\\\=30*10[/tex]

       = 300 square feet

Area of four triangles  = 4 * 300

                                    = 1200  square feet

Area to be painted blue = area of circle + area of 4 triangles

                                        = 706.50 + 1200

                                        = 1906.50 square feet

Area painted by one bucket blue paint  = 350 sq. feet

Number of paint buckets needed = 1906.50 ÷ 350

                                                       = 5.44

                                                       = 6

6 buckets of blue paint is needed.

Cost of 6 buckets of blue paint = 85.50 * 6

                                                    = $ 513

Each part of the design needs two coats.

So Cost for  two coats = 2 * 513

                                     = $ 1026

Square:

Side  =  40 ft

Area of square = side *side

                         = 40*40

                         = 1600 sq. ft

Area of square to be painted yellow = area of square - area of circle

                                                           = 1600 - 706.50

                                                          = 893.50 sq.ft

Area painted with  one bucket of yellow paint = 250 sq. ft

Number of yellow paint buckets needed = 893.50 ÷ 250

                                                                    = 3.574

                                                                    = 4

4 buckets of yellow bucket is needed

Cost of 4 buckets of yellow bucket = 64.50 * 4

                                                          = $ 258

Each part of the design needs two coats.

So Cost for  two coats = 2 * 258

                                     = $ 516
