Ann’s car used 7 gallons of gas during a trip how far did Ann drive

8 trips the plane can take between cities before running out of fuel.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given that,

Total gas available 65000 gallons round down as 60000

Gas is consumed between New York and Los Angeles = 7460 round-up as 7000

The number of trips from New York and Los Angeles = 60000/7000 = 8.57.

Since the number of trips should be a whole number so 8 will be the correct answer.

Hence "8 trips the plane can take between cities before running out of fuel".

is that the question?

The point (-4,15) is found in the second quadrant, where x-values are negative (here, -4) and y-values are positive (here, 15) in the Cartesian coordinate system.

The point (-4,15) lies in the second quadrant of the Cartesian coordinate system. In the second quadrant, the x-coordinate is negative and the y-coordinate is positive. This is because the Cartesian coordinate system is divided into four quadrants based on the signs of the x (horizontal) and y (vertical) values: Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), and Quadrant IV (positive x, negative y).

I think the answer is D, because P is the new price, n is the original price, then you multiply 0.25 by the original price and then subtract it by the original price.

answer is 2720

solution below

First, converting R percent to r a decimal

r = R/100 = 4.5%/100 = 0.045 per year.

solving our equation:

A = 2000(1 + (0.045 × 8)) = 2720  

A = $2,720.00

the total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 4.5% per year for 8 years is $2,720.00

600t = 480(18 – t) should be it

Answer:

Option D. 600t = 480( 18-t )

Step-by-step explanation:

An airplane flew at an average rate of 600 miles per hour fro Tokyo to Seattle.

Let the airplane travels for t hours so distance covered by the airplane will be = speed × time

    = 600t miles

Similarly, average speed in return trip was 480 mile/hour. So distance covered in return trip = speed × time

= 480 ( 18-t ) [ since time taken by plane in round trip was 18. So time taken in return trip will be ( 18-t) ]

Therefore, distance traveled in one trip = distance covered in return trip

600t = 480( 18-t )

Option D is the answer.

One Solution: Simplify to get 5x+4=5x+4

The equation 4x + x + 4 = 8x - 3x + 4 has infinitely many solutions.

To solve the equation 4x + x + 4 = 8x - 3x + 4, we first simplify both sides

5x + 4 = 5x + 4

Next, we subtract 5x from both sides:

4 = 4

Since the equation simplifies to a true statement (4 = 4), this means that the equation is true for any value of x.

Hence, the equation has infinitely many solutions.

Answer:

  The interest rate = 6 %

Explanation:

We have  I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years.

 Here principal, p = 200 $

          Number of years , t = 3

        Interest received, I = 36$

       We need to find rate of interest.

Substituting

       36 = 200 x r x 3

      r = [tex]\frac{36}{200*3}[/tex]= 0.06 = 6%

  The interest rate = 6 %

Answer:20%

Step-by-step explanation:

Let r represent rate of interest.

We have been given that Mika invested $200 into a certificate of deposit. After 6 months, the balance was $220.

We will use simple interest formula to solve our given problem.

I = Amount of interest,

P = Principal amount,

r = Rate of interest in decimal form,

t = Time in years.

First of all, we will find amount of interest by subtracting $200 from $220 as:

6 month = 1/2 year = 0.5 year

Upon substituting our given values in simple interest formula, we will get:

Upon dividing both sides by $100, we will get:

Since interest rate is given in decimal, so we will multiply 0.2 by 100 to convert our answer in percentage.

Therefore, the interest rate on the deposit was 20% and option B is the correct choice.

2. Tom's brother saw Muscle Fitness, which offers $20 off of the $80 fee. Membership is $15 a month plus another $5 a month.

First, solve the one time fee

$80 - 20 = $60

Next, solve the monthly fee

15 + 5 = 20

(a) The expression: Let x = month

20x + 60

(b) Remember the previous question.

Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month.

(a) Write a expression to represent the membership cost of Platinum Gym for x months.

Let x = months

20x + 60 is your expression

No. In fact, it will be the same. Waiving the $20 off the one-time fee would give the same amount of one-time payment, 60. Membership and Mandatory equipment maintenance would also add up to $20 a month.

So you use the point slope stuff.

y-y=m(x-x)

To find the slope, subtract two y values over two x values that are also sibtracted in the same order.

IN this case, you could do (-4 - 23)/-5 - 10

Which is 9/5

So now you plug in the x and y values (doesnt matter which point)

y+4=9/5(x+5)

Make it slope intercept form

y=9/5x-13

positive = greater than 0.

Therefore we have the inequality:

Julie's age based on the scenario given cab be obtained by using the equation ; j + 2j - 6 = 36

Let :

Julie's age = j ________(1)

Helga's age = 2j - 6 ____(2)

Sum of their ages = 36

Hence, to find Julie's age, j we can use the equation :

(1) + (2) = 36

j + (2j - 6) = 36

j + 2j - 6 = 36

To find Julie's age, we can use the equation ;

j + 2j - 6 = 36

3j - 6 = 36

3j = 36 + 6

3j = 42

j = 42 / 3

j = 14

Answer:

The length is 5.7 feet.

Step-by-step explanation:

A rectangle has a width of 7.9 feet and a perimeter of 27.2 feet.

Let the length be = x

Perimeter is given by :

[tex]P=2(L+W)[/tex]

We get;

[tex]27.2=2(x+7.9)[/tex]

=> [tex]27.2=2x+15.8[/tex]

=> [tex]2x=11.4[/tex]

Dividing both sides by 2 to get x;

x = 5.7 feet

Hence, length is 5.7 feet.

Let Angle A = X

Since Angle B is the same, angle B is also X

Then angle C = X +45

Add the 3 angles together: X +X +X +45 = 3x+45

That equals 180 degrees:

3x+45 = 180

Subtract 45 from both sides:

3x = 135

Divide both sides by 3:

X = 135/3

X = 45

Angle A = 45

Angle B = 45

Angle C = 45+45 = 90

Final answer:

To find the height of the mountain, the tangent of the angle of elevation is multiplied by the distance to the base of the mountain. With an angle of 23°29' and a distance of 16,194.6 feet, the height of the mountain is approximately 7,026 feet.

Explanation:

To find the height of the mountain when Bob is 16,194.6 feet from the mountain's base and the angle of elevation is 23°29', we can use trigonometry, specifically the tangent function which is the ratio of the opposite side to the adjacent side in a right triangle.

Steps to Solve:

Convert the angle 23°29' to decimal degrees: 23° + 29'/60 = 23.483°.

Use the tangent function: tan(angle) = opposite side/adjacent side, where the adjacent side is the distance from Bob to the base of the mountain and the opposite side is the height of the mountain.

Calculate the height: height = tan(angle) * distance to the base.

Substitute the known values and solve: height = tan(23.483°) * 16,194.6 feet.

Using a calculator, tan(23.483°) ≈ 0.4338. Multiplying this by 16,194.6 gives us approximately 7026.03668 feet.

Therefore, the height of the mountain to the nearest foot is 7,026 feet.

When, a rectangle has an area of 364.5cm² if it’s length is 27 cm. Then, the perimeter of the rectangle is 81 cm.

To find the perimeter of a rectangle when the area and the length are known, first calculate the width using the area formula. The area of a rectangle is given by the formula Area = length x width. Given that the area is 364.5 cm² and the length is 27 cm, the width can be found as follows:

Width = Area / Length = 364.5 cm² / 27 cm = 13.5 cm

Once you have both the length and width, the perimeter can be calculated using the formula Perimeter = 2 x (length + width). So, the perimeter would be:

Perimeter = 2 x (27 cm + 13.5 cm) = 2  x 40.5 cm = 81 cm

Hence, the perimeter of the rectangle is 81 cm.
