Answer:Juan live 384 miles from the mountains.

Step-by-step explanation:

Let x be the speed  of Juan for trip to the mountains

Time taken by Juan to reach the mountains=8 hours

then distance traveled by Juan for trip to mountain= speed × time=8x..........(1)

Time taken by Juan to reach the home= 6 hours

Speed increased by 16 miles per hour ∴ the resultant speed to reach the home by Juan =x+16

then distance traveled by Juan to reach the home =speed × time

= (x+16)6......................(2)

Now distance is same in both the case (1) and (2),we get

8x= (x+16)6

⇒8x=6x+96..............(by solving brackets)

⇒2x=96..............(subtracting 6x from both sides )

⇒x=48....................(dividing 2 from both sides)

Putting this value in (1) ,we get

Distance traveled by Juan for trip to mountain =8×48=384 miles.

∴ Juan live 384 miles from the mountains.

By using the rate and time of journey, it is determined that Juan lives 384 miles away from the mountains.

This question is about calculating the distance based on the rate and time of travel. Let's denote the distance to the mountains as 'D'. According to the question, Juan drove to the mountains and it took 8 hours. On his way home, there was no traffic and he was able to travel at a faster rate, which took 6 hours.

Let's denote the speed to the mountains as 'S', therefore his speed back was 'S + 16' (16 miles per hour faster). From the formula speed = distance/time (D = S*T), we know that the distance to and from the mountains remained the same, so we can set up the following equation to solve for the unknown distance D:

8S = 6(S + 16)

Solving for 'S' we get 48 mph. We can substitute S=48 into the first equation to get D = 8S = 8*48 = 384 miles. So, Juan lives 384 miles away from the mountains.

The remainder when dividing 23870 by 38 is 16.

To find the remainder when dividing 23870 by 38, you divide the larger number (the dividend) by the smaller number (the divisor). If the division operation does not produce a whole number, the 'left over' digits are considered the remainder. When you divide 23870 by 38, the quotient (or the answer) is 628, and the remainder is 16. Therefore, 16 is the remainder when 23870 is divided by 38.

1. When you rotate a figure counterclockwise, is that a positive rotation or a negative rotation? It is a positive rotation. Positive rotations are counterclockwise or anti-clockwise.

2. Rotating from the x-axis to the y-axis is a rotation of how many degrees? it is generally 180 degrees. To rotate a figure 180 degrees, we apply the rule (x, y) → (-x, -y).

i dont really know about 2. but i think for 1. is it is a negative rotation if you spin it like that.

Answer:

Step-by-step explanation:

The dimensions of the rectangle are 3 inches by 12 inches. This conclusion is achieved by using the supplied information that the rectangle is four times as long as it is wide, and the area is 36 square inches.

The problem is describing a rectangle whose length is four times its width and has an area of 36 square inches. The formula for the area of a rectangle is length x width. Given the rectangle is four times as long as it is wide, we can represent the width as 'w' and the length as '4w'. Therefore, the calculation would look as follows: 4w * w = 36. Solving this equation we get w^2=9, so w=3. Consequently, the length would be 4*3=12. Therefore, the dimensions of the rectangle are 3 inches by 12 inches.

Answer:

The distance is 55 units.

Step-by-step explanation:

Think of the bottom left corner of the rectangles, the shared vertex, as the origin of a coordinate plane. The positive x-axis is the lower 108-unit long horizontal side, and the positive y-axis is the left vertical 98-unit long side. The bottom left vertex is (0, 0). The center of the small rectangle is at (10, 16). The center of the large rectangle is at (54, 49). Now use the distance formula to find the distance between those two points.

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] d = \sqrt{(54 - 10)^2 + (49 - 16)^2} [/tex]

Answer:

A. 12

Step-by-step explanation:

i= use complicated conjugate to search out definite quantity of 8 + 12i

i = 12i

i= twelve × ei 90°

i = twelve × (cos 90° + i sin 90°)

r = |i| = twelve

The absolute value of the complex number 8 + 12i is found by squaring the real part, squaring the imaginary part, adding these two results, and then taking the square root. This results in the square root of 208.

The absolute value of a complex number a + bi is calculated through the formula sqrt(a² + b²). So, to find the absolute value of the complex number 8 + 12i, we substitute a with 8 and b with 12. We can perform the calculations as follows:

13  By the factor theorem, if the function is divisible by x - 3 then f(3) = 0. So we have:-

To solve this equation, distribute, combine like terms, and isolate the variable, x.

To solve this equation, we need to simplify both sides and isolate the variable, x.

Starting with the left side, distribute the 3 to the terms inside the parentheses: 3x - 15 - 5x = 25 + 6x.

Combine like terms on both sides of the equation: -2x - 15 = 25 + 6x.

Add 2x to both sides of the equation and add 15 to both sides: -15 - 25 = 6x + 2x.

Simplify the equation: -40 = 8x.

Finally, divide both sides by 8 to solve for x: x = -5.

Answer:

16 hours

Step-by-step explanation:

Given: There are 4 people in your crew.

Each spent 4 hours of laying sod.

To find the person hours, we have to multiply the number of people (4) by the amount of hours each person spent (4).

Total number of hours = Number of persons * Number of hours spent

Total number of hours = 4 x 4 = 16 hours

Therefore, the total amount of hours is 16.

Answer: {-10, +10}

Step-by-step explanation: A common mistake in this problem would be to say that if x² = 100, x must equal 10.

Remember however that before you do anything else you must set the equation equal to 0.

So our first step is to subtract 100 from both sides to get x² - 100 = 0. Next, factor the left side to get (x + 10)(x - 10) = 0.

So either x + 10 = 0 or x - 10 = 0.

Solving for x in each equation, we have x = -10 or x = +10.

So our answer is not just 10, it's -10 or +10.

Answer:

[tex]y=\$20,000\cdot (0.90)^x[/tex]

Step-by-step explanation:

We have been given that Kelly bought a new car for $20,000. The car depreciates at a rate of 10% per year. We are asked to write an equation to model the car's value.

Since car's value depreciates by 10% per year, so value of car is depreciating exponentially.

We know that an exponential decay function is in form [tex]y=a\cdot (1-r)^x[/tex], where

a = Initial value,

r = Decay rate in decimal form.

Let us convert 10% into decimal form as:

[tex]10\%=\frac{10}{100}=0.10[/tex]

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

[tex]y=\$20,000\cdot (1-0.10)^x[/tex]

[tex]y=\$20,000\cdot (0.90)^x[/tex]

Therefore, our required equation would be [tex]y=\$20,000\cdot (0.90)^x[/tex].

Step-by-step explanation:

Answer:

60 dollars.

Step-by-step explanation:

Markup is nothing but the difference between the selling price of a good or service and its cost. It is expressed as a percentage above the cost. In short, we can say that  it is the added price over the total cost of the good or service that provides the seller with a profit.

Original price = 50 dollars

ADD: 20% on original price = Markup price = 50(20/100) = 10 dollars

Hence Sales price = 50+10 = 60 dollars
