Answer:

Widyh = 8 units

Step-by-step explanation:

Perimeter = 2/width+length)

then:

48 = 2(W+L)

W = L-8

W = Width

L = Length

then:

48 = 2((L-8)+L)

48 = 2(2L88)

48 = 2*2L - 2*8

48 = 4L - 16

48 + 16 = 4L

64 = 4L

L = 64/4

L = 16

W = L-8

W = 16-8

W = 8

Check:

48 = 2(16+8)

48 = 2*24

a line is paralll yo y=4x-2 and intersects the point (5,-11). what is the equation of this parallel line

victus00 [196]

The equation of line parallel to given line is: y=4x-31

Step-by-step explanation:

Given equation of line is:

$y = 4x-2$

The equation of line is in slope-intercept form so the co-efficient of x is the slope of the line.

Let m1 be the slope of the given line

then

m1 = 4

Let m2 be the line that is parallel to given line

As we know that the slopes of parallel lines is equal so

m1=m2 = 4

The slope-intercept form of equation of line is:

$y = m_2x+b$

Putting the value of slope

$y = 4x+b$

to find the value of b, putting (5,-11) in the equation

$-11 = 4(5) + b\\-11 = 20+b\\b = -11-20\\b = -31$

Putting the value of b

$y=4x-31$

Hence,

The equation of line parallel to given line is: y=4x-31

The diameter of a baseball is about 1.4 in.

nexus9112 [7]

You need to find the surface area and the volume. The formula for surface area is 4*3.14(pi)*radius^2 which is equal to 6.5144 inches^2 in this case. The amount of rubber needed to fill it is equal to the volume. The formula for volume of a sphere is 4/3*3.14(pi)*radius^3, just plug in the number (remember radius is half of diameter) and that will give you the answer!
