A rental car company charges a basic fee plus a price per mile. One customer drove 250 and paid 56.50, while another customer drove 400 and paid 79. Write an equation in slope - intercept form for the cost of renting a car. Use your equation to find how much it would cost to drive 325 miles?

answer:

0.4lbs per stick of butter

step-by-step explanation:

objective: find the weight of each stick of butter

total pounds: 3.8 - 1.4 (bag of sugar) = 2.4lbs

2.4lbs is the amount of pounds of butter but we need to find the weight of each stick - to do this we must divide our weight of the butter by the six sticks of butter

2.4 ÷ 6 = 0.4lbs per stick of butter

The answer to question 34:

Let 'x' = pounds of gravel. The ratio of mulch to gravel is given 2 1/4 | 1 1/3. Which equals 9/4 | 4/3 = 27/16.

So the total gravel and much is equal to x + 27/16x = 172  

Solving for 'x'

43/16 x = 172    

x = 172 (16/43) = 64 pounds of gravel           Mulch = 27/16x = 64 (27/16)= 108 pounds

The answer to question 35:

A.) 1,080 beats per minute at rest and 1,500 beats per minute while running.

B.) 4,500 (while running) - 3,240 (at rest) = 1,260 more beats while running than at rest.

Hi Nicole,

Question 34:

2 1/4 pounds of mulch for every 1 1/3 pounds of gravel.

Gravel - 172 / 1 1/3 = 129

Mulch - 172 / 2 1/4 = 76.44444...

Question 35:

a. 18 beats in 15 seconds.

b. 25 beats in 10 seconds.

Part A:

Find beats per minute:

1 minute = 60 seconds

60 / 15 = 4

18 x 4 = 72

Answer - 72 beats per minute (Resting)

150 beats per minute (Running)

Part B:

72 times per minute resting

Find 25 times in 10 seconds in minutes,

1 minute = 60 seconds

60 / 10 = 6

25 x 6 = 150

So while running the friend has 150 beats per minute.

Find the number of beats in 3 minutes for both:

Resting:

72 x 3 = 216

216 beats in 3 minutes

Running:

150 x 3 = 450

450 beats in 3 minutes

Subtract:

450 - 216 = 234

Answer - Your friend's heart beat is 234 beats more in 3 minutes than at rest.

The first one,

[tex]a=1\times a[/tex]  is the multiplicative identity property.

The identity element of multiplication of real numbers is 1.

This means that if you multiply any real number [tex]a[/tex] by [tex]1[/tex] you get the same real number.

The second one,

[tex]3-3x=3(1-x)[/tex] is the distributive of property of multiplication over subtraction.

Answer:

a = 1a ---> multiplicative identity property of 1

3 - 3x = 3 (1 - x) ---> distributive property of multiplication (over subtraction)

Step-by-step explanation:

a = 1a holds the the multiplicative identity property of 1.

This property of identity states that whenever you multiply any number with 1, the result is same as the original number. It means that 1 has no effect when multiplied with any number.

3 - 3x = 3 (1 - x) holds the distributive property of multiplication (over subtraction)

This distributive property is used to multiply a single term with two or more terms inside the brackets or you can say the equations which are in the form a (b + c).

Its main purpose is to expand the terms by first multiplying each term inside the bracket with the term outside the term and then adding/subtracting the like terms together.

The 0 is needed as a placeholder between the decimal point and the hundredths' digit. For numbers between 0.1 and 0.2, there is a 1 in the tenths' place: 0.11, 0.12, 0.13, and so on. For numbers between 0.2 and 0.3, there is a 2 in the tenths' place: 0.21, 0.22, 0.23, and so forth.

The midpoint of 0.1 and 0.2 is 0.15.

The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.

To find the midpoint we just have to add both the numbers and then divide by 2.

So, midpoint be,

= (0.1+0.2)/2

=0.3/2

=0.15

Thus the midpoint of 0.1 and 0.2 is 0.15.

1 blue square on drawing is length 1/4 in but that means 4ft in reality.

so one blue square area correspongs to 4x4 = 16 square feet.

(a) there 6 tiles for the batrhroom = 6x16 sq.ft = 96 sq.ft and the cost will be $480

(b) bedroom + living area = 7x8-8 tiles = 48 tiles = 48 x 16 sq.ft. = 768 sq.ft = 85.33 sq. yards. So the cost will be 85.33*18=$1535.94

(c) unit cost for tile: $5/sq.ft

unit cost for carpet: $1535.94/768sq.ft = $2/sq.ft

The tile has a greater unit cost ($5 per sq.ft) than carpet ($2 per sq.ft)

The exact costs for tiling and carpeting cannot be determined without the dimensions of the rooms. However, converting square inches to square feet or yards allows for cost calculation. Generally, tile has a greater unit cost than carpet when both are compared per square foot.

Unfortunately, we cannot provide exact costs for tiling the bathroom or carpeting the bedroom and living room as the dimensions of these rooms are not provided. However, once you have total area in square inches, you can convert it into square feet or square yard by knowing that 1 square foot is 144 square inches and 1 square yard is 1296 square inches. After converting, you can then multiply the areas by the respective unit costs of the ceramic tile and the carpet to get the total costs.

For the unit cost comparison, generally, carpet is sold by square yard and tile is sold by square foot. To make an accurate comparison, we need to convert the price of carpet from per yard to per foot by dividing it by 9 (since 1 square yard = 9 square feet). If, for example, the carpet cost is $18 per square yard, this would equate to $2 per square foot. Comparing this to the tile cost of $5 per square foot, you can see that the tile has a greater unit cost.

x, y=25x+500

range = {500, 525, 550, 575, 600, 625}

For a given function we can define the domain as the set of the possible inputs of that function, and the range as the set of the possible outputs of that function.

We will find that the range is: {500, 525, 550, 575, 600, 625}

So, if for a given function f(x) we know that the domain is {x₁, x₂, ..., xₙ} then the range will be {f(x₁), ..., f(xₙ)}

Here we have the function:

y = f(x) = 25*x + 500

And we have the domain: {0, 1, 2, 3, 4, 5}

Then the values in the range are:

Thus the range is: {500, 525, 550, 575, 600, 625}

Answer:

10 * 10 = 100

20 * 10 = 200

30 * 40 = 1200

Step-by-step explanation:

Step 1: In both the factors, we have zeros. for example, multiplying 20 and 10, we get 200.

Step 2: Since there are two zeros (adding zeros in multiple), therefore, in the result we get 2 zeros

More examples:

10 * 200 = 2000, there are 3 zeros (1 +2 = 3 zeros)

200 * 200 = 40000, there 4 zeros ( 2+2 = 4)

Hope this will help you understand the concept.

When multiplying two multiples of 10, the number of zeros in the product equals the sum of the zeros in the factors. This is due to each zero representing a power of ten. The product in a multiplication of multiples of 10 will have a number of zeros that matches the combined number of zeros in the factors.

When both factors in a multiplication problem are multiples of 10, the result is a number with a zero for each zero in each factor.

This is because each zero represents a power of ten, and when we multiply by 10, we are increasing the power of ten.

For example, if we have two factors, 30 and 40 (which are multiples of 10), the product would be 1200. In this case, 30 has one zero and 40 has one zero, so the product, 1200, has two zeros.

The rule can also be applied to larger multiples of 10.

For instance, if we multiply 200 by 4000, the product would: 200 (two zeros) x 4000 (three zeros) equals 800,000 (five zeros).

The total number of zeros in the product equals the sum of the zeros in the factors.
