Step-by-step explanation:

a room that needs to be tiled is 12 1/2 feet wide by 14 feet long. tiles that mesure 2x2 are $0.79 per tile. Tiles that measure 3x3 are 1.25 per tile. which size tile should be used for this project to save the most money? How many tiles would be needed? How much would you spend on them? HELP PLEASE!

Answers

Answer:

Step-by-step explanation:

Area of the room is 12.5(14) = 175 ft²

2x2 tiles are 4 ft²

175 /4 = 43.75 tiles so 44 will be needed

44($0.79) = $34.76

3x3 tiles are 9ft²

175/9 = 19.4444... so 20 will be needed

20($1.25) = $25.00

the larger tiles will cost $9.24 less than the smaller tiles.

Obviously some of the tiles will need to be cut to fit as the length and width of the room are not always a uniform number of tiles for either side.

Robin currently has 50 subscribers on her You.Tube channel, and Dimitri currently has 17 subscribers. Robin gains 4 subscribers every week, while Dimitri gains 7 subscribers each week.

Part A: Set up a system of equations to shows each person's subscribers.

Part B: After how many weeks will Robin and Dimitri have the same number of subscribers?

Part C: How many subscribers will Robin and Dimitri have when their subscriber count is equal?

Answers

Answer:

Part A :

Robin : 50 divided by 4 = 12.5, Robin took 12.5 Weeks to get to 50 subscribers.

Dimitri : 17 divded by 7 = 2.4, Dimitri took 2.4 weeks to get to 7 subscribers.

Part B : In 7 weeks, Dimitri will have 66 subscribers, And in 4 weeks, Robin will have 66 subscribers. So after 7 weeks for Robin and 4 for Dimitri

Part C , They will have 66 subscribers. After 7 weeks Dimitri will have 66 subcribers, and after 4 weeks Robin will have 66 subscribers.

Explanation :

I have calculated out Robins and Dimitris subscribers counts with math.

Part A: The attached image is for Robin but I didn't have time for Dimitri.

Dimitri: Currently has 17 subscribers, 7x11=77. 17+77 = 94 and the same goes for Robin.

Robin: Currently he has 50 subscribers, 4x11=44. 50+44 = 94.

Part B: After 11 weeks Robin and Dimitri will have the same number of subscribers.

Part C: Robin and Dimitri will have 94 Subscribers when their subscriber count is equal.

Hi!

Seeing this, we can right away take the [tex]\frac{0}{35}[/tex] away to make it easier, because 0/35 is 0. Now, we are left with:

[tex]-\frac{31}{35} - \frac{2}{35}[/tex]

Since the denominators (the 35s) are the same, we do not have to mess with those. We simply subtract the numerators (-31 - 2) and we get -33. Therefore, your answer is :

You decide to reduce the amount you spend eating out by $150 a month and invest the total saved at
the end of each year in your retirement account. How much will the account be worth at 5% in 15
years? (Use Table 13.1.) (Do not round intermediate calculations. Round your answer to the
nearest cent.)

Answers

The type of savings is the saving of uniform amount with interest applied to the sum of the amount in the account.

The amount the account is worth after 15 years is approximately $38,841.1

Reasons:

The amount saved per month = $150

Amount saved per year, A = 12 × $150 = $1,800

The interest rate on the account, i = 5%

The amount, F, in the account after 15 years is given as follows;

The uniform series compound amount factor formula is presented as follows;

[tex]\displaystyle F = \mathbf{\frac{A \cdot \left[ \left(1 + i \right)^n - 1 \right]}{i}}[/tex]

Therefore;

[tex]\displaystyle F = \frac{1,800 \times \left[ \left(1 + 0.05 \right)^{15} - 1 \right]}{0.05} \approx \mathbf{38,841.4}[/tex]

The amount the account is worth after 15 years to the nearest cent is approximately $38,841.4.

the distance between 2 points can be seen as the Hypotenuse of a right-angled triangle with the legs being the x and y coordinate differences.

and so, we use Pythagoras

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90 degree angle).

distance² = (5 - 0)² + (2 - -2)² = 5² + 4² = 25 + 16 = 41

16) A: decimal form

17) A: 0.44

18) A: 24 ÷ 27

1) 1.7 ÷ 8.5

We need to change them to whole numbers by shifting the decimal points one place to the right to get; (17/85)

2) 50 ÷ 0.1

Shift decimal one place to the right to get;

500/1

Quotient = 500

3) 0.86 ÷ 0.02

The dividend is usually the numerator. Let us shift both numerator and denominator by two decimal places to the right to get; 86 ÷ 2

Thus, new dividend = 86

4) 6.9 ÷ 0.3

Move decimal points one place to the right to get;

69 ÷ 3 = 23

5) 75.64 ÷ 0.61

Move decimal points two places to the right to get;

7564 ÷ 61

Numerator written as a factor of denominator gives;

(124 × 61)/61

Quotient = 124

6) 7.26 ÷ 0.22

Move decimal points two places to the right to get;

726/22

Numerator written as a factor of denominator gives;

(33 × 22)/22 = 33

7) 5.12 ÷ 0.10

Move decimal points two places to the right to get;

512/10 = 51.2

8) A 0.75 m pink ribbon was cut into 0.25 m strips. Thus;

Number of pieces = 0.75/0.25

Move both decimals 2 places to the right to get;

75/25 = 3 pieces

9) A bottle contains 27.5 ounces

You take 1.65 ounces for each dose.

Number of doses per bottle = 27.5/1.65

Move decimal points two places to the right; 2750/165

Number of doses per bottle = 16.67 doses

10) She earned Php256.25 for gardening.

She worked 20.5 hours the month.

Amount earned per hour = 256.25/20.5

move decimal places two points to the right to get;

Amount earned per hour = Php 12.5

11) 5.26 times 10

move decimal place two points to the right to get;

(526 × 1/100) × 10 = 52.6

12) 59 ÷ 7

Nearest multiple of 7 to 59 is 8.

Thus, 59 ÷ 7 = 8³/₇

⇒ 8.43

13) The one that gives a quotient of 6.78 is;

61 ÷ 9

14) How many 7 does 86 have?

This is; 86 ÷ 7

Nearest multiple of 7 to 86 is 84 which is 12 × 7

Thus, there are 12 numbers of 7 in 86.

15) Remainder if you divide 59 by 9

Nearest multiple of 9 to 59 is 54 which is 9 × 6.

Remainder = 59 - 54 = 5

16) When divisor is bigger than the dividend, it means the denominator is bigger than the numerator and so the quotient is an improper fraction which is a decimal.

17) 4 ÷ 9 = 0.444

Approximating to one decimal place = 0.4

18) The correct mathematical sentence with never ending decimal is;

24 ÷ 27
