Answer:

w = 48

w = 196

Step-by-step explanation:

Width = w

Length = l = 4 + 4w

Use the values for length and width above along with the given value for perimeter in the formula for perimeter.

P = 2l + 2w

488 = 2(4 + 4w) + 2w

488 = 8 + 8w + 2w

488 = 8 + 10w

488 - 8 = (8 + 10w) - 8

480 = 10w

(480)/10 = (10w)/10

48 = w

w = 48

The width is 48 yards.  Use this value to solve for length.

l = 4 + 4w

l = 4 + 4(48)

l = 4 + 192

l = 196

The length is 196 yards.

What is the value of x<br><br> Triangle with sides 10 6 x-6
Grace [21]
Given that the triangle is a right angled triangle, to solve for x we shall use the Pythagorean theorem given by:
c^2=a^2+b^2
where:
c is the hypotenuse
a and b are the legs.
c=10
a=6
b=(x-6)
thus plugging the values in the equation and solving for x we get:
10^2=6^2+(x-6)^2
100=36+x^2-12x+36
100=x^2-12x+72
0=x^2-12x-28
factoring the above we get:
0=(x+2)(x-14)
hence
x=-2 or x=14
given that there is no negative distance then
x=14
thus the value of x is 14

The graph of a linear function is shown on the grid. (-3,3.6) (5,2) What is the rate of change of y with respect to x for this f
lilavasa [31]

Answer:

rate of change = -0.32

Step-by-step explanation:

Rate of change = slope,m

m =  \frac{y2 - y1}{x2 - x1}  \\ m =  \frac{3.6 - 2}{ - 3 - 2}  \\ m =  \frac{1.6}{ - 5}  \\ m =  \frac{ - 0.32}{1}

Does anyone know the answer?
kolezko [41]

Answer:

Part A: 9.75x > 195

Part B: x > 20

Step-by-step explanation:

Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.

We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195

divide both sides by 9.75 to solve for x

x > 20

The radius of a circle measures 15 ft. What is the circumference of the circle?
Pie

Answer:

\boxed {\tt 94.2 \ feet}

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

c= \pi d

where d is the diameter. We are given the radius, so let's find the diameter.

The diameter is twice the radius.

d=2r

The radius is 15 feet.

d= 2 * 15 \ ft

Multiply.

d= 30 \ ft

Now we know the diameter. Substitute 30 feet in for d.

c= \pi d

c=\pi * 30 \ ft

We are using 3.14 for pi, so substitute it in.

c=3.14 * 30 \ ft

Multiply.

c= 94.2 \ ft

The circumference of the circle is 94.2 feet.
