since LJ = LK + KJ, replace the letters with the corresponding equations. You'd get:
LJ = (7x-10) + 28
LJ = 7x + 18
Do you need an integer or is that okay?^

A 9,000-lb load is suspended from the roof in a shopping mall with a 16-ft-long solid aluminum rod. The modulus of elasticity of
Westkost [7]

Answer:

Step-by-step explanation:

Given:

elongation, x = 0.50 in

Force, f = 9000 lb

Young modulus, E = 10,000,000 psi

Maximum Stress, Sm = 30000 psi

Length, L = 16 ft

Converting ft to in,

12 in = 1 ft

=16 × 12 = 192 in

Young modulus, E = stress/strain

Stress = force/area, A

Strain = elongation, x/Length, L

E = f × L/A × E

1 × 10^7 = stress/(0.5/16)

= 26041.7 psi

Minimum stress = 26041.7 psi

Maximum stress = 30,000 psi

Stress = force/area

Area = 9000/26041.7

= 0.3456 in^2

Stress = force/area

Area = 9000/30000

= 0.3 in^2

Using minimum area of 0.3 in^2,

A = (pi/4)(d^2)

0.3 in^2 = (pi/4)(d^2)

d = 0.618 inches

diameter, d = 0.618 inches

20 POINTS N BRAINLIEST!!16.Alun has a part-time job working as a bus boy at a
olchik [2.2K]

Answer:

a)E=.05t +34

b)$54

c)$600

Step-by-step explanation:

a) he gets 5% of tips out of all tips people gave to the restaurant , 5% --> .05 (as a decimal) --> this is "t"

he earns an extra $34 a night of work. --> this is the constant

E= --> the total earned that night

E=.05t +34

b) simply plug in the total tip into the equation

E=.05(400) + 34

E=$54

--> he earned $54 that night

c) since we are given the total earned that night, we now plug in for y. in this case we plug "$64" for y

we find t, which is tip the restaurant was given

--> 64 = .05t +34

-34. -34

30= .05t ---> divide by .05 each side

t= $600

the restaurant was tiped 600 dollars and Alun was paid 64 dollars that night of work

hoped this helped:)

The exterior angle of a certain regular polygon is 60°. How many sides does the polygon have?.
givi [52]
<h3>Answer:  6</h3>

Work Shown:

E = exterior angle = 60 degrees

n = number of sides of the regular polygon

n = 360/E

n = 360/60

n = 6

The regular polygon has 6 sides.
