Answer: 1\dfrac{3}{4}\text{ feet}

Step-by-step explanation:

Given: Length of sandwich = 10\dfrac12\text{ feet}=\dfrac{21}{2}\text{ feet}

Total people = 14

If everyone gets a same sized piece , then length of each piece should be

\dfrac{\text{ Length of sandwich}}{\text{Total people}}

=\dfrac{\dfrac{21}{2}}{14}\text{ feet}\\\\=\dfrac{21}{2\times14}\text{ feet}\\\\=\dfrac{7}{2\times2}\text{ feet}\\\\=\dfrac{7}{4}\text{ feet}\\\\=1\dfrac{3}{4}\text{ feet}

Hence, length of each piece = 1\dfrac{3}{4}\text{ feet}

Find the distance between the points (-7,-6)
aleksklad [387]

Answer:

Step-by-step explanation:

formula

d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

Givens

x2 = 2

x1 = - 7

y2 = -6

y1 = - 6

Solution

d = sqrt( (2 - - 7)^2 + (-6 - - 6)^2 )

d = sqrt( 9^2 + (-6 + 6)^2 )

d = sqrt(9)^2

d = 9

assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury and the standard deviation is
julia-pushkina [17]

Given M = 120, σ = 5.6

P (117.4 <x<120)

P (" 117.4-120 5.6 < X-M 120-120 5.6

P(-0.46 < 220)

= 0.5= P(-0.46 <2)

= 0.5 0.3212

0.1788

The standard deviation is 0.1788

Standards contain technical specifications or other precise criteria intended to be used consistently as rules, guidelines, or definitions. They make life easier and help increase the reliability and effectiveness of many of the products and services we use. . Most state regulations require drivers to have liability insurance and stipulate the exact amount of coverage required.

Standard definitions are established as a basis for rules, examples, or comparisons. An example of a standard is a policy governing what 7th graders must learn. An example of a standard is music that has been played many times over the years.

Which expression is equivalent to 2cos^2(x/2)- cos(x)?<br> Edge 2020
olchik [2.2K]

Given:

The expression is

2\cos^2(\dfrac{x}{2})-\cos (x)

To find:

The expression which is equivalent to the given expression.

Solution:

We have,

2\cos^2(\dfrac{x}{2})-\cos (x)

We know that,

\cos x=2\cos^2 (\dfrac{x}{2})-1

Using this formula, the given expression can be written as

2\cos^2(\dfrac{x}{2})-\left(2\cos^2(\dfrac{x}{2})-1\right)

=2\cos^2(\dfrac{x}{2})-2\cos^2(\dfrac{x}{2})+1

=1

Therefore, the given expression is equivalent to 1.
