<h2>Answer:150 electricians,10 inspectors</h2>

Step-by-step explanation:

The solution uses unitary method.

The unitary method is a method for solving a problem by first finding the value of a single unit and finding the required value by multiplying the single unit value.

Given,

Each generator employs $3$ electricians.

Every $60$ electricians require $4$ inspectors.

So,every electrician require $\frac{4}{60}=\frac{1}{15}$ inspectors.

Anthony's department has $50$ generators.

Since each generator requires $3$ electricians, $50$ generators require $3\times 50=150$ electricians.

Since each electrician needs $\frac{1}{15}$ inspectors, $150$ electricians need $\frac{1}{15} \times 150=10$ inspectors.

So,to maintain peak performance Antony's department requires $150$ electricians and $10$ inspectors.

|x-3| < 5 please help

ratelena [41]

Answer:

$\left|x-3\right|$

The graph is also attached.

Step-by-step explanation:

Given the expression

$|x-3|\:$

Apply absolute rule:

$\mathrm{If}\:|u|\:0\:\mathrm{then}\:-a\:$

so the expression becomes

$-5$

$x-3>-5\quad \mathrm{and}\quad \:x-3$

solving condition 1

x−3<5

Add 3 to both sides

x−3+3<5+3

x<8

solving condition 2

x−3>−5

Add 3 to both sides

x−3+3>−5+3

x>−2

combining the intervals

$x>-2\quad \mathrm{and}\quad \:x$

Merging overlapping intervals

$-2$

Therefore,

$\left|x-3\right|$

The graph is also attached.

Find the length of rhombus whose diogonals are length 12 cm and 16 cm

grin007 [14]

In ΔAOD (AD) =(AO)

2+(OD)

2 =36+64 AD

2 =100

AD= 100

=10cm

Rhombus has all sides equal

AB = AD = BC = CD = 10 cm

the radious of each wheel of a car is 16 inches at how many revolutions per minute should a spin balancer be set to balance the

Alex Ar [27]

Answer:

revolutions per minute for 16 inches is 946 / minute

revolutions per minute for 14 inches is 1081 / minute

Step-by-step explanation:

Given data

radius = 16 inch

speed = 90 mph = 90/60 = 1.5 miles/minute = 1.5 × 5280 feet /12 inches = 95040 inches /minute

radius 2 = 14 inches

to find out

revolutions per minute

solution

first we calculate the circumference of the wheel i.e. 2× $\pi$ ×radius

circumference = 2× $\pi$ ×16

circumference = 32 $\pi$

we know that revolution is speed / circumference

revolution = 95040/32 $\pi$

revolution = 945.38 / minute

we have given radius 14 inches than revolution will be i.e.

revolution = speed / circumference

circumference = 2× $\pi$ ×14

circumference = 28 $\pi$

revolution = 95040/ 28 $\pi$

revolution = 1080.43 / minute
