Does a rectangle have four congruent sides?
ololo11 [35]

Answer:

NO.

Step-by-step explanation:

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. So, in other words, 2 shapes  or figures in geometry are congruent if they have the exact same size and shape.

A rectangle has 2 pairs of parallel sides. One pair is longer than the other pair. Therefore, to be congruent, all sides have to be equal, which is a square, not a rectangle. So the answer is NO.

Shorty’s Muffler advertises it can install a new muffler in 30 minutes or less. However, the work standards department at corpor
pav-90 [236]

Answer:

The installations at the Maumee branch would you expect to take more than 30 minutes is 10.

Step-by-step explanation:

Consider the provided information.

Let x is the installations at the Maumee branch take more than 30 minutes.

The work standards department at corporate headquarters recently conducted a study and found that 20% of the mufflers were not installed in 30 minutes or less.

Therefore, π=0.20

The Maumee branch installed 50 mufflers last month.

Thus, n=50

Mean of the distribution: μ=nπ

Substitute the respective values in the above formula.

μ=(50)(0.20)

μ=10

Hence, the installations at the Maumee branch would you expect to take more than 30 minutes is 10.

How do you rearrange the equation (2x) /(4pi) +((1-x) /2) =0 to solve for x?
USPshnik [31]
\frac{2x}{4 \pi } + \frac{1-x}{2} =0 \\ &#10; \frac{x}{2 \pi } + \frac{1-x}{2} = 0
Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π    / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )
