Answer: 4.5

Answer:

The correct answer would be C = 533,800

Step-by-step explanation:

The formula for circumference is C = 2πr. To find the radius you must divide the diameter by 2.

Radius = 85000

now we have C = 2 * 85000 * 3.14

C = 533,800

Scientific Formula = 5.338 x 10^6

Width=19

Length=17

72-4=68/2=34/2= 17 length

72-4=68+4=38/2=19 width

GIVEN: y = 3x + 5

--> slope of given line = 3

--> This means that your equation must have the same slope, or "m"

FORMULA OF A LINE: y = mx + b

--> Use point-slope form to find "b"

POINT SLOPE FORM: y - y₁ = m ( x - x₁ )

--> Plug in your given point AND the slope of the given line

y - 5 = 3 ( x - 4 )

y - 5 = 3x - 12

y = 3x - 7

The given formula A=LWH, which represents the volume of a box, needs to be solved for L. This can be accomplished by dividing both sides of the equation by WH, which leads to the equation L = A / (WH).

You have given the formula for the volume of a box, which is A=LWH. Here, A is the area, L is the length, W is the width, and H is the height. You are asked to solve this formula for L. This means we want to express L in terms of the other variables, W, H, and A.

To isolate L, you divide both sides of the equation by WH. So, the equation becomes:

L = A / (WH)

This equation shows L (length) in terms of A (area), W (width), and H (height).

15/8 as a percentage is 187.5

Answer:

Weight of parcel to the nearest whole kilogram = 6 kg

Explanation:

 Weight of parcel = 12 lbs 8 oz

 1lb = 16 oz  also we have 1lb = 454 g

 Weight of parcel = 12 lbs 8 oz = 12 + (8/16) lbs = 12.5 lbs

  Weight of parcel in g = 12.5*454 = 5675 g

  Weight of parcel = 5675 g = 5.675 kg

  Weight of parcel to the nearest whole kilogram = 6 kg

To convert the weight of a 12 lbs 8 oz parcel to kilograms, you first convert the weight to ounces, then to grams, and finally to kilograms. The final conversion results in a weight of approximately 5.67 kg, which is rounded to the nearest whole number as 6 kg.

The weight of a parcel can be converted from pounds and ounces to kilograms using a two-step process. First, you need to convert the entire weight into ounces, and then convert that result to grams. Finally, convert grams to kilograms.

To convert 12 lbs 8 oz to ounces, calculate as follows: (12 lbs × 16 oz/lb) + 8 oz. This equals 192 oz + 8 oz = 200 oz.

To convert ounces to grams: 200 oz × 28.35 g/oz gives 5670 g.

To find the weight in kilograms, divide the number of grams by 1000, because 1 kg = 1000 g. So, 5670 g ÷ 1000 g/kg gives 5.67 kg. To the nearest whole kilogram, the package weighs 6 kg.

Mr. Hower will save $96.01 if he pays cash for the computer instead of making monthly payments.

To determine how much money Mr. Hower will save if he pays cash for the computer instead of making monthly payments, we need to compare the total cost of both options.

First, let's calculate the total amount paid with monthly payments:

Down payment: $510

Monthly payments: 8 payments of $35.75

Total paid with monthly payments = Down payment + (Monthly payment amount × Number of payments)

$510 + ($35.75 × 8) = $510 + $286 = $796

Now, let's compare it to the cash price:

Cash price: $699.99

Savings if pays in cash = Total paid with monthly payments - Cash price

$796 - $699.99 = $96.01

So, Mr. Hower would save $96.01 if he pays cash for the computer instead of using the monthly payment option.

Answer:

88:56 = 11:7 pounds.

Step-by-step explanation:

Drop the pound sign. I live in Canada and I can't make that symbol. I'll add something at the end. We just want to divide 144 into a ratio of of 11:7

Step One

Add the two ratios together 11 + 7 = 18

Now set up a ratio to solve for 11 parts out of 18

11:18 = x:144         Proportion

11 / 18 = x / 144    Equation: Cross mulitiply

11*144 = 18x         Combine the left side

1584   = 18x         Divide by 18

1584 / 18  = x

88 = x

That is the larger amount (11 is larger than 7)

Find the smaller amount

144 - 88 = 56

The two amounts are in the ratio of 11:7

88:56 = 11:7

The inequality to describe S, the weight of the special sundae in kilograms, at Ping's Ice Cream Palace is S > 2, indicating the sundae weighs more than 2 kilograms.

The question involves creating an inequality to describe the weight of a special sundae, S, at Ping's Ice Cream Palace. Since the sundae contains over 2 kilograms of ice cream, this means the weight of the sundae is greater than 2 kilograms. However, since there can be any number of toppings, there is technically no upper limit to the weight. Therefore, the inequality to describe S, the weight of the special sundae in kilograms, would be:

S > 2

This inequality indicates that the weight of the sundae is strictly more than 2 kilograms, considering the ice cream and any added toppings.

Rounding the world's largest aloha shirt measurement, 4.26 meters, results in 5 to the nearest ones place and 4.2 to the nearest tenths place.

To round the measurement of the world's largest aloha shirt to the nearest ones place, we look at the decimal part of the number 4.26. Since the digit after the decimal is 6 (which is 5 or higher), we round up the number 4 to 5. Therefore, when rounded to the nearest ones place, 4.26 becomes 5.

To round to the nearest tenths place, we only need to consider the first digit after the decimal point. In this case, that digit is 2, which means there is no need to round up or down; the tens digit stays the same. So, when rounded to the nearest tenths place, 4.26 remains 4.2.

Answer: The required expression will be

[tex]\frac{6000-p}{24}[/tex]

Step-by-step explanation:

Since we have given that

Amount that Liam has = $250

Amount that he and his classmates spent on  present for their teacher =$p

Number of students in which $p will split = 24

According to question,

Amount that left to Liam is given by

[tex]250-\frac{p}{24}\\\\=\frac{6000-p}{24}[/tex]

Hence, the required expression will be

[tex]\frac{6000-p}{24}[/tex]

To calculate how much money Liam has left, subtract the cost of the present from his initial amount of money. The expression that represents this is $250 - ($p/24).

To find out how much money Liam has left after buying the present, we need to subtract the cost of the present from the initial amount of money Liam had. The cost of the present can be calculated by dividing the total cost by the number of classmates, which is 24. So, the cost of the present is $p/24. Therefore, the expression that represents how much money Liam has left is:

$250 - ($p/24)

Answer:

On the 18th day.

Step-by-step explanation:

You have to find common multiples for 9 and 2.

The common multiples of 2 are: 2, 4, 6, 8, 10, 12, 14, 16, 18 and more

The common multiples of 9 are: 9, 18, and more

The least same multiple is 18 so the answer is 18.

Based on the lowest common multiple of 2 and 9, both classes will have art on the 18th day.

The lowest common multiple of two numbers are the lowest multiple that each number can divide without a remainder.

For instance, 2 can divide 18 to get 9.  Similarly, 9 can divide 18 to get 2.

On the other hand, the multiples of 2 include 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, etc.

The multiples of 9 include 9, 18, 27, 36, etc.

The common factor or multiple between 2 and 9 is 18.

Final answer:

After comparing the fractions of the chocolate cake (5/12) and the marble cake (1/2 or 6/12) eaten by the family, it's clear that they ate more marble cake as 6/12 is greater than 5/12.

Explanation:

Jared cut a chocolate cake into 12 equal parts and a marble cake into 6 equal parts. After his family ate 5 slices of chocolate cake and 3 slices of marble cake, we want to determine which type of cake they ate more of. To compare the quantities directly, we consider the size of each individual slice. A chocolate cake is cut into 12 pieces, so each slice represents 1/12 of the full cake. The marble cake is cut into 6 pieces, meaning each slice is 1/6 of the entire cake. Therefore, when the family ate 5 slices of chocolate cake, they consumed 5/12 of the chocolate cake, and consuming 3 slices of marble cake equates to 3/6, or 1/2 of the marble cake.

To compare these fractions, we can notice that 1/2 is equivalent to 6/12 when converted to have a common denominator. Comparing 5/12 and 6/12, it is clear that 6/12 is greater. Thus, the family ate more marble cake than chocolate cake.

An equation in standard form for the situation where you have $0.8 in dimes and quarters is 10x + 25y = 80, where x represents the number of dimes and y represents the number of quarters.

To create an equation in standard form that represents the situation where you have $0.8 in your backpack in dimes and quarters, let x represent the number of dimes and y represent the number of quarters. Recall that the value of a dime is $0.10 and the value of a quarter is $0.25.

Each dime is worth $0.10, so the total value of the dimes will be 0.10x dollars. Each quarter is worth $0.25, so the total value of the quarters will be 0.25y dollars. The total amount of money is $0.8, so the equation representing this situation in standard form is:

0.10x + 0.25y = 0.8

However, to get the equation in standard form, we usually want integers as coefficients. To eliminate the decimals, we can multiply every term by 100:

10x + 25y = 80

This equation is now in standard form and represents the combination of dimes and quarters adding up to $0.8.

Answer:

1)For example we need to find 54 -41.2

Step 1: Write down the both numbers, one under the other, with the once digit in same line.

54

-41.2

Step2: Now,add zeros so the numbers to make the same length .

54.0

-41.2

Step3: Then subtract normally, remembering to put the decimal point in the answer

54.0

-41.2

12.8

2)Here we need to subtract same place values of second number from the first number starting from right side, We can see to subtract 2 from 0 we need to take carry from 4 (4 will become 3)so that it will become 10 to subtract 2 from it ,thus we get our answer 12.8.

The decimal subtraction problem 0.72 - 0.58 requires regrouping from the tenth place. This is because you cannot subtract 8 from 2 without regrouping. The final answer, after regrouping and subtracting is 0.14.

A decimal subtraction equation that requires regrouping from the tenths could be as follows: 0.72 - 0.58. In this problem, you cannot subtract 8 (in the hundredth place) from 2 (also in the hundredth place) without regrouping because 2 is less than 8. Therefore, you need to regroup from the tenth place.

To do this, you take one-tenth (0.10) from the tenth place, leaving you with 0.62 instead of 0.72. This action adds ten hundredths (0.10) to the hundredths place, turning our 0.02 into 0.12. Now, you can subtract 8 from 12 in the hundredth place, and you can subtract 5 from 6 in the tenth place, leaving you with the answer: 0.14.

Answer:

Step-by-step explanation:

There are 42 people who had breakfast.  Each person had either egg or pancake or both.

Of these only eggs were 2/3 and both were 2/3

Hence the remaining ate only pancakes

i.e. portion of persons who ate pancakes = 1-(1/7+2/3)

= 4/21

Total no of people in the restaurant = 42

Of those people who ate eggs only= 1/7 (42) = 6

No of persons who ate both pancakes and eggs = 2/3(42) = 28

Hence no of persons who ate only pancakes =42-(6+28) = 8

95.20-50=  45.20

45.20/.40= 113

they went 113 minutes over their plan

The family exceeded their plan by 113 minutes.

To find out how much time the family exceeded their plan, we need to subtract the included minutes from the total minutes used and then divide by the overage rate. The included minutes in the plan are 900, and the cost per minute over the limit is $0.40. The total amount paid by the family is $95.20. Let's calculate:

Total minutes used = Total amount paid - Cost of the plan = $95.20 - $50 = $45.20
Exceeded minutes = Total minutes used - Included minutes = $45.20 / $0.40 = 113 minutes

The family exceeded their plan by 113 minutes.
