Answers

Answer:

1 : 10000

Step-by-step explanation:

Energy of a photon of x-rays of wavelength = 0.05 nm

Energy of a photon of visible light of wavelength = 500 nm

The ratio is given as;

Sam has already worked for 27.7 hours this week. He washes cars, and can wash a car in 2.5 hours. He wants to work over 60.2 hours this week.

Answers

The question is incomplete ; we could calculate the least number of cars he can still wash for the week expressed in inequality form.

Answer:

x > 13 ; 13

Step-by-step explanation:

Given that :

Anticipated work hour for entire week = 60.2 hours

Hours worked = 27.7 hours

Rate of car wash = 2.5 per hour

Hours left to work for the week :

60.2 - 27.7 = 32.5

Hours left / unit rate of car wash

32.5 / 2.5

= 13

Hours worked +( hours left * unit rate) > anticipated hours

27.7 + 2.5x < 60.2

2.5x > 60.2 - 27.7

2.5x > 32.5

x > 32.5 / 2.5

x > 13

Hence ; Sam could still wash over 13 cars this week

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.

Answers

Answer:

x = 12Side = 23 units

Step-by-step explanation:

STU is an equilateral triangle. And:

ST = 2x - 1SU = 5x - 37TU = x + 11

All sides are equal. Then take one pair and solve for x:

2x - 1 = 5x - 373x = 36x = 12

Substitute x to find the side length:

2x - 1 = 5x - 37 = x + 11 = 23
