1 13 over 15 divided by 1 2 over 5

Part (A)

The blue car travel 38.5 miles on 1.25 gallons of gasoline

∴ The unit rate of the blue car = 38.5 ÷ 1.25 = 30.8  miles per gallon

==========================================

Part (B):

The red car travel [tex]23 \frac{1}{5}[/tex] miles on [tex]\frac{4}{5}[/tex] gallons of gasoline.

[tex]23 \frac{1}{5}[/tex] = 23.2   and   [tex]\frac{4}{5}[/tex] = 0.8

∴ The unit rate of the red car = 23.2 ÷ 0.8 = 29  miles per gallon

==========================================

Part (C):

Which car could travel the greater distance on 1 gallon of gasoline?

The answer: by reviewing part (A) and part (B)

So, the blue car can travel the greater distance on 1 gallon of gasoline.

Given problem is:

[tex](7.14\times10^{10})+(3.21\times10^{10})[/tex]

step by step solution:

we will add similar elements.

[tex]10^{10}(7.14+3.21)[/tex]

=[tex]10^{10} (10.35)[/tex]

Now converting [tex]10^{10}[/tex] in decimal form we get 10000000000 (10 zeroes)

Now multiplying 10.35 with 10000000000 we get 103500000000 (8 zeroes)

or we can change it to exponential form like [tex]1.035\times10^{11}[/tex]

11 because when you count from the extreme right end '0' and come counting to the left side, you skip 11 numbers till you reach the first number '1'. And when you put a decimal after 1st number, so the last '0' is at the 11th place, that is why it is [tex]10^{11}[/tex] .

The total surface area of both lake superior and lake Michigan is 53,978² mi.

I used addition to add up the surface area of both lakes.

Final answer:

The total surface area of Lake Superior and Lake Michigan is 53,978 square miles, calculated by adding the surface areas of both lakes using basic arithmetic.

Explanation:

To calculate the total surface area of both Lake Superior and Lake Michigan, you simply add the surface areas of the two lakes together. The surface area of Lake Superior is 31,700 square miles and the surface area of Lake Michigan is 22,278 square miles.

Using addition, the total surface area is calculated as follows:

Lake Superior: 31,700 square miles

Lake Michigan: 22,278 square miles

Total surface area: 31,700 + 22,278 = 53,978 square miles

The strategy or tool used to solve this problem is basic arithmetic, specifically addition. By adding the two areas together, we find that the combined surface area of Lake Superior and Lake Michigan is 53,978 square miles.

The first thing we need to do is define our unknowns.

Jiri's age can be represented by x

Pamela's age can be represented by 2x

So,

2x+x = 69

3x = 69

x = 23

So, Jiri is 23, and Pamela is 46.

Answer:

Speed of Charles = 12 Km per hour

To convert it into meters per minute, we follow the following procedure

1 Km =1000 meter

1 hour = 60 minute

Now 12 Km per hour = [tex]\frac{12\times 1000}{60}[/tex]

    = 12,000 ÷ 60

   = 200 meter per minute

Charles, who runs at a rate of 12 kilometers per hour, runs at a speed of 200 meters per minute when converted using the facts that there are 1,000 meters in a kilometer and 60 minutes in an hour.

The speed of Charles, who runs at a rate of 12 kilometers per hour, can be converted to meters per minute using the fact that there are 1,000 meters in one kilometer and 60 minutes in one hour.

First, convert the distance from kilometers to meters. 12 kilometers is equal to 12,000 meters because one kilometer is equal to 1,000 meters.

Next, since the speed is given per hour and the question asks for the speed in terms of minutes, we need to convert the time component. There are 60 minutes in an hour, so we divide 12,000 meters by 60 minutes to get the speed in meters per minute.

So, following these steps: (12 kilometers * 1,000 meters) / 60 minutes = 200 meters per minute. So, Charles’s speed is 200 meters per minute.

Multiply all the numbers together to get your answer.

The three numbers are 93,94,95

The three consecutive even numbers whose sum evaluates to 282 are 92, 94, and 96

As the term consecutive implies, the numbers who come one after the other are  called consecutive.

In case of consecutive even numbers, those even numbers who are adjacent to each other.

Example: 2,4,6 are consecutive events but 2,6,12 are not as there are events between 2 and 6 and between 6 and 12, so they are not closest to each other.

Let the first even of those three consecutive numbers whose sum is 282 be denoted by [tex]2n[/tex]

Then, we get the rest of the two evens as [tex]2n + 2, 2n+4[/tex]

Since their sum is 282, therefore,

[tex]2n + (2n+2) + (2n+4) = 282\\2n +2n + 2n + 2 + 4 = 282\\6n + 6 = 282\\\\\text{Subtracting 6 from both the sides}\\\\6n = 282 - 6 = 276\\\\\text{Dividing both the sides by 6, we get}\\\\n = \dfrac{276}{6} = 46[/tex]

Thus, the three consecutive evens whose sum is 282 are:

[tex]2n = 2(46) = 92\\2n + 2 = 94\\2n + 4 = 96[/tex]

Therefore, the three consecutive even numbers whose sum evaluates to 282 are 92, 94, and 96

Answer:

$1050.00

Step-by-step explanation:

The leasing company has a base rate for the first 15,000 miles, but has an additional charge of $500+0.25/mile for each mile over the 15,000 miles.

Bradley has already driven 4,300 miles in first three months.

And he drives a similar amount for the rest of the year. So we can calculate on an average how much distance does he cover each month:

So he has driven 4,300 miles in three months, on an average the distance he drives a month, is:

[tex]\frac{4300}{3}=1433.33 [/tex] miles

So over 12 months he drove:

[tex]1433.33\times 12=17200[/tex] miles

Now, for first 15,000 miles he needs to pay some base rate. Now we will calculate how much extra has he driven beyond 15,000 miles.

So he has driven:

[tex]17200-15000=2200[/tex]

He has driven 2,200 miles extra beyond first 15,000 miles.

So the additional amount he needs to pay is:

[tex]\$500+\$(0.25\times 2200)=\$500+\$550=\$1050.00[/tex]

Therefore, the additional amount that is in addition to the base rate that he needs to pay is $1050.00.

Answer: Bradley has to pay $1050 extra to the leasing company.

Step-by-step explanation:

Distance traveled by Bradley's car in 3 months i.e.1/4 of year =4300 miles

Distance traveled by Bradley's car in 1 year(12 months) =4 times he drove for 1/4 of year=4×4300=17200 miles

Now,Extra distance covered by car=17200-15000=2200 miles

As there is a additional charge of $500 + $0.25/mile for each mile over the 15,000.

Thus, he has to pay extra amount=$500+$0.25 times extra distance=$500+$(0.25×2200)=$500+$550=$1050

∴ Bradley has to pay $1050 extra to the leasing company.

A = 5/6(B + C)

multiply 6 on both sides

6A = 5(B + C)

divide 5 from both sides

6A/5 = B + C

subtract B from both sides

6A/5 - B = C

The solution of the equation for C will be 6A / 5 - B.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

The expression is given below.

A = 5/6 (B + C)

Then solve the equation for C, then we have

6A / 5 = (B + C)

      C = 6A / 5 - B

If I understand the question, then he would be able to make 22 2/3 patties if each patty requires 1 1/2 pound of secret formula and he only has 34 pounds.

Answer:

5 is the solution with the greater value; -2/3 is the other solution.

Step-by-step explanation:

Set each factor of (3x+2)(x-5)=0 equal to zero and solve for x in each case:

3x+2 = 0 => 3x = -2 => x = -2/3

x-5 = 0 => x = 5

To solve the given equation, set each factor equal to zero and solve for x. The solutions are x=-2/3 and x=5, with x=5 as the highest value.

To solve the equation (3x+2)(x-5)=0, we will use the basic principle that if the product of two factors is zero, then at least one of them needs to be zero. Therefore, either 3x+2=0 or x-5=0.

If 3x+2=0, then 3x=-2, which simplifies further to x=-2/3.

If x-5=0, then x=5.

Therefore, the solutions are x=-2/3 and x=5. Among these solutions, the highest value is x=5.
