Answer:

Speed = 3.75 miles per hour.

Step-by-step explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

$Speed = \frac{distance}{time}$

$S = \frac{d}{t}$

Given the following data;

Distance, d = 3/4 miles

Time, t = 1/5 hour

Substituting into the equation, we have;

$Speed, S= \frac{3/4}{1/5}$

$Speed, S = \frac{3}{4}*5$

$Speed, S = \frac{15}{4}$

Speed, S = 3.75mph.

Therefore, Josie's speed is 3.75 miles per hour.

The number of goals scored by a soccer team varies directly as the number of shots on goal. If the Lakeside Bears scored 4 goals

enot [183]

Since it varies directly, divide the number of shots by the number of goals:

48 shots / 4 goals = 12

This tells you they score a goal every 12 shots.

Multiply shots needed by number of goals:

12 x 3 = 36

They need 36 more shots to score 3 more goals.

A rectangular plot of land is to be enclosed by a fence. One side is along a river, and does not need to be enclosed. If the tot

Bad White [126]

Answer:

Width 150 meters.

Length = 350 meters.

Step-by-step explanation:

Let us assume the width of the fence = k meters

So, both sides = k + k = 2k meters

Also, the TOTAL fencing length = 600 m

So, the one side length of the fence = (600 - 2 k) meters

AREA = LENGTH x WIDTH

⇒ A(k) = (600 - 2k) (k)

or, A = -2k² + 600 k

The above equation is of the form: ax² +bx + C

Here: a = - 2 , b = 600 and C = 0

As a< 0, the parabola opens DOWNWARDS.

Here, x value is given as: $x = \frac{-b}{2a}$

Solving for the value of k similarly, we get:

$k = \frac{-b}{2a} = \frac{600}{2(-2)} = 150$

Thus the desired width = k = 150 meters

So, the desired dimensions of the plot is width 150 meters.

And length = 650 - 2k = 650 - 300 = 350 meters.

Graph the line that has a slope of 1/4 and includes the point (0,8)

Alex787 [66]

Step-by-step explanation:

Equation of line:

$y = mx + c$

where m is the slope

and c is the y-intercept (the value of y when x = 0)

In this case, given the slope = 1/4

and y-intercept is 8 (from the point (0,8))

The equation of the following line is:

$y = \frac{1}{4} x + 8$
