Answer:

Width: 13/2 ft.

Length: 12 ft.

Step-by-step explanation:

Let's assume the width is x

This means that the length is 2x-1, because it it one less than double the width.

The formula for the area of a rectangle is length*width, so

(2x-1)*x=78

Now let's solve for x

2x^2-x=78

2x^2-x-78=0

Use the quadratic formula

x=13/2 and x=-6

x cannot be negative, so we can rule out x=-6 and are left with x=13/2.

Substituting x back into our original assumptions, we now know that

The width is x=13/2 and

The length is 2x-1=2(13/2)-1=12

Final answer: The width is 13/2 ft. and the length is 12 ft.

Answer:

10x - 20

Step-by-step explanation:

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll help you assuming some things. First of all, for a two dimensional shape, the perimeter is defined as the distance around it. Suppose we have a rectangle whose dimensions are:

The solution is,  the area of the square is 4/9 in^2.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object. Area of a square (A) is the product of its length (l) and width (l).

i.e. A= l× l

here, we have,

In this problem we have a square

so

the area of a square is

A=b^2

we have

b=2/3 in

substitute

A=(2/3)^2

A=4/9 in^2

Hence, The solution is,  the area of the square is 4/9 in^2.

The number of FTE needed to be hired to cover the additional procedures per 7.5 day work is:

= 1.

Step-by-step explanation:

a) Data and Calculations:

                                                Endoscopies      EP Studies    Total

Projected number of studies         60                      5              65

Time in minutes for per study         5                     15

Total time required (in minutes) 300                     75           375

Full-time Employee (FTE) works 7.5-hour day or 450 minutes (7.5 * 60) per day.

b)The number of full-time employees (FTE) needed to be hired to cover the additional procedures per 7.5-day work is 1.  The FTE has 450 minutes available for the additional procedures.  She will only require 375 minutes.  Therefore, she has extra (idle) time of 75 (450 - 375) minutes per workday.

so 100%+20%=120% for the amount of cereal

Find 100%

120%=p

divide by 6

20%=p/6

times by 5

100% = 5p/6

Henry:

5p/6=83% Its the same amount of cereal but for 83% of the price

so 100-83=17%

Answer:

r=8.4cm

v=3119.5cmcube

volume of a cylinder

=pie r square height

pie=22/7

22/7×8.4×8.4×h=3119.5cm cube

221.76cmsquareh=3119.5cm cube

___________________________

221.76cm square(both sides)

h=14.07cm

The height of the cylinder is h =  14.09 cm

Given data:

To find the height of the cylinder,  the formula for the volume of a cylinder: V = πr²h, where V is the volume, r is the radius, and h is the height.

Given that the radius is 8.4 cm and the volume is 3119.5 cm³, substitute these values into the formula and solve for h.

3119.5 cm³ = π(8.4 cm)²h

To isolate h, divide both sides of the equation by π(8.4 cm)²:

h = 3119.5 cm³ / (π(8.4 cm)²)

Now, calculate the approximate value of h as:

h ≈ 3119.5 / (π * 8.4²)

≈ 3119.5 / (3.14 * 70.56)

≈ 3119.5 / 221.1264

≈ 14.0989 cm

Hence , the height is 14.09 cm

Answer:

15/24 or 5/8

Step-by-step explanation:

Well 9 are female

The rest of the 24 has to be male so

24-9=15

15/24 or 5/8

The fraction of male swimmers is 5/8.

Given,

24 swimmers are swimming in the pool.

9 of them are female.

We need to find what fraction of male swimmers.

We write in two parts numerator and denominator.

= Numerator / Denominator

= Number of required items / Total number of items

Find the total number of swimmers.

= 24

Find the number of male swimmers.

= Total swimmers - Female swimmers

= 24 - 9

= 15

Find the fraction of male swimmers.

= Number of male swimmers / Total number of swimmers
= 15 / 24

Taking out the common factor

= 3 x 5 / 3 x 8

= 5/8

Thus the fraction of male swimmers is 5/8.
