Answer:

The scale of the map is inch = 20 feet.

This statement must be incorrect or the fraction of the inch is missing.

Because 6" long, at a scale of one inch = 20 feet, would only be 120 feet x 120 feet.

120 x 120 = 14,000 ft^2 and each of the four quadrants wouls only be 3600 ft^2.

Answer:

10 min.

Step-by-step explanation:

Remember d = rt

The distance from bear's house to beehive = 75m and 225m = distance from beehive to piglet's house

Let r = normal rate of speed

The normal time is 300/r without stopping

75/r = time from bear's house to beehive

225/(r + 15) = time from beehive to piglet's house

So, time from beehive to piglet's house + time at beehive + time from bear's house to beehive = normal time without stopping

225/(r + 15) + 2.5 + 75/r = 300/r

225r + 2.5r(r + 15) + 75(r + 15) = 300(r + 15)

225r + 2.5r^2 + 37.5r + 75r + 1125 = 300r + 4500 Let's remove the deceimal by multiplying thru by 10

2250r + 25r^2 + 375r + 750r + 11250 = 3000r + 45000

25r^2 + 3375r + 11250 =  3000r + 45000

25r^2 + 375r - 33750 = 0

25(r^2 + 15r - 1350) = 0

25(r - 30 )(r + 45) = 0

r = 30 or -45     But, the rate cannot be negative, therefore r = 30

The journey takes 300/30 = 10 min.

By solving a system of equations, we will see that the journey takes 10 minutes.

Let's define the variables:

We have that usually, the bear travels 300 meters in the time T, then we have:

S*T = 300m.

And in this situation, the bear also travels in the same time T, then we have:

First, the bear walks 1/4 of the distance, this is:

S*T/4

Then the bear stops for 2.5 minutes

Then the bear walks at 15m/min faster than usual for a time t..

S*T/4 + (S + 15 m/min)*t = 300m

Such that:

t + T/4 + 2.5 min = T.

Then we can write:

t = T - T/4 - 2.5 min = (3/4)*T - 2.5 min

Replacing that we get:

S*T/4 + (S + 15 m/min)*( (3/4)*T - 2.5 min) = 300m

Then we have a system of equations:

S*T = 300m.

S*T/4 + (S + 15 m/min)*( (3/4)*T - 2.5 min) = 300m

To solve this, we isolate one of the variables in one of the equations, I will isolate S in the first one:

S = 300m/T

Now we can replace this in the other equation:

(300m/T)*T/4 + (300m/T + 15 m/min)*( (3/4)*T - 2.5 min) = 300m

300m/4 +  (300m/T + 15 m/min)*( (3/4)*T - 2.5 min) = 300m

Now we can solve this for T.

75m + 225m + (11.25 m/min)*T - (750m/min)/T - 37.5m = 300m

(11.25 m/min)*T - (750m/min)/T - 37.5m = 0m

If we multiply both sides by T, we get:

(11.25 m/min)*T^2 - (750m/min) - 37.5m*T = 0m

This is a quadratic equation, the solutions are given by:

[tex]T = \frac{37.5m \pm \sqrt{(-37.5m)^2 - 4*(11.25 m/min) (-750m/min)} }{2*(11.25 m/min)} \\\\T = (37.5m \pm 187.5m)/( 22.5 m/min)[/tex]

We only care for the positive solution, which is:

T = (37.5 m + 187.5m)/(22.5 m/min) = 10 min

So the journey takes 10 minutes.

Answer:

10 yards

Step-by-step explanation:

;)

The required length of the longer side is 10 yards.

Perimeter, is the measure of the figure on its circumference.

Here,
Let's assume that the length of one side of the rectangle is x yards. According to the problem, the other side of the rectangle is 3 yards longer than twice the length of this side. So, the length of the other side can be expressed as 2x + 3 yards.

The perimeter of a rectangle is the sum of the lengths of all its sides. So, we can write an equation to represent the problem:

Perimeter = 2 × length + 2 × width

Substituting the expressions for length and width, we get:

27 = 2(x) + 2(2x + 3)

27 = 2x + 4x + 6

27 = 6x + 6

21 = 6x

x = 3.5

So, the length of one side of the rectangle is 3.5 yards. The other side of the rectangle is 2(3.5) + 3 = 10 yards.

Therefore, the length of the longer side is 10 yards.

Answer:

The slope of the graph of plane A is 430, its speed is 430 miles per hour.

The slope of the graph of plane B is 460, its speed is 460 miles per hour.

Plane B is flying faster.

Step-by-step explanation:

The speed of the airplane is the slope of the function, that is, change in distance by change in time. From table, we notice that curve is a first order polynomial, also known that linear function:

Plane A

The slope of the graph of plane A is 430, its speed is 430 miles per hour.

Plane B

The slope of the graph of plane B is:

[tex]v = \frac{1840\,mi-460\,mi}{4\,h-1\,h}[/tex]

[tex]v = 460\,\frac{mi}{h}[/tex]

The slope of the graph of plane B is 460, its speed is 460 miles per hour.

Therefore, plane B is flying faster.
