Answer:
10 cars
Step-by-step explanation:
Variable c = car
Step 1: form an equation
175c + 1886 = 115 + 965 + (1240)2
Step 2: isolate variable c and solve
175c + 1886 = 3560
175c = 3560 - 1886
175c = 1674
c = 1674 ÷ 175
c = 9.56....
*He will not get paid until the full car is detailed. Therefore, decimals (seen as half a car) will not pay him anything.*
Step 3: round up to the nearest whole number
c = 10
Answer:
11/125
Step-by-step explanation:
0.088
= 88 x 0.001
= 88 x (1/1000)
= 88/1000 (divide top and bottom by 8)
= 11/125 (simplest form)
Answer:
Sewage treatment and nitrous oxide
Step-by-step explanation:
Sewage to treatment and nitrous oxide is correctly paired with the greenhouse gases that it increases.
Greenhouse gas refers to gases that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect.
Examples of greenhouse gases and the most important greenhouse gases are methane, carbon dioxide (CO2), and water vapor.
Human activities such as fossil-fuel combustion are responsible for increase in the atmospheric concentration of various greenhouse gases, especially carbon dioxide, methane and ozone.
Only one because there is one variable and the combined coefficients of x are non-zero.
(0.75(x+40)=0.70(x+20), 0.05x=14-30=-16, x=-320)
