Choose the more precise measurement from the pair 54.1 cm and 54.16 cm.
Tamiku [17]

Answer:

a

Step-by-step explanation:

Precision means that a measurement using a particular tool or implement produces similar results every single time it is used. For example, if you step on a scale five times in a row, a precise scale would give you the same weight each time. In math and science, calculating precision is essential to determine if your tools and measurements work well enough to get good data. You can report precision of any data set using the range of values, the average deviation, or the standard deviation.

Cos45*/sec30*+cosec60*​
Lera25 [3.4K]

Answer:

= (√3+4√2)/2√6

Step-by-step explanation:

To evaluate cos45*/sec30*+cosec60*​

First according to trigonometry identity

sec 30 = 1/cos30

cosec 60 = 1/sin60

Substitute

cos45*/sec30*+cosec60*​

= cos45/(1/cos30) + 1/sin60

= cos45coss30 + 1/sin60

= 1/√2 * √3/2 + 1/(√3/2)

= √3/2√2 + 2/√3

= (√9+4√2)/2√6 +

= (√3+4√2)/2√6

the length of a rectangle is equal to triple the width . if the perimeter is 8 centimeters .what is the length and the width of
madam [21]

Answer:

Length = 3 cm

Width = 1 cm

Step-by-step explanation:

Let the length of rectangle be l and width of rectangle be w.

According to problem,

l = 3w  {Length of rectangle is equal to triple the width}

And Perimeter,P = 8 cm

Since, P = 2 ( l + w )

or 8 = 2( l + w)

Plug l =3w in the above perimeter equation.

We get:

8 = 2( 3w + w)

8 = 2(4w)

8 = 8w

or    w = 1 cm

Then length ,l = 3w =3 * 1 = 3 cm

Hence length of rectangle is 3cm and width of rectangle is 1cm.

each cube inside the rectangular prism has an edge length 3/4 inch.What is the volume of the rectangular prism?
NNADVOKAT [17]

Answer:

\frac{27}{64}n\,\,cubic\,\, inches

Step-by-step explanation:

Given: Edge length of cube = \frac{3}{4}\,\,inch

To find: Volume of the rectangular prism

Solution:

A cube is a three-dimensional solid object which has 12 edges, 8 vertices and 6 faces.

A rectangular prism is a solid three-dimensional object which has six faces that are rectangles.

Let n denotes number of cubes inside the rectangular prism

Volume of one cube = (edge)^3=(\frac{3}{4})^3 =\frac{27}{64}  cubic inches

So, volume of rectangular prism = volume of n cubes =  \frac{27}{64}n\,\,cubic\,\, inches

Someone please help me I am confuzzled+need the answer asap

w = number of weeks

b(w) = number of books read after w weeks

====================================

b(w) = 12 translates to "after w weeks, Katy will have read 12 books" or put another way "Katy will have read 12 books after w weeks". The 'w' is a placeholder for some number

====================================

b(2) = 10 means "Katy has read 10 books after 2 weeks". We use the same basic idea talked about above, but we replace w with 2. At the same time, we use 10 instead of 12.

====================================

b(3) = f means "Katy has read f books after 3 weeks" or "after 3 weeks, Katy has read f books". Like w, the f is a placeholder for some number.
