Answer:
3
Step-by-step explanation:
2•3=6 +2=8 8 squared is 8•8 which is 64. This problem is quite simple.
Answer:
X=3
Step-by-step explanation:
Step 1: Find the square root of 64
since there is an exponent of 2 around your paranthesis, you must get rid of that first, by finding the square root of the first part of the equation and 64. then you will have (2x+2)=8
Step 2: Subtract 2
next subtract 2 from both sides of the equation, and you will have 2x=6
Step 3: divide by 2
lastly, divide each side by 2. you will get x=3
Cindy's argument is incorrect. 1/3 is a rational number because it can be expressed as the ratio of two integers. The fact that the decimal representation of 1/3 does not terminate does not make it irrational.
Cindy's argument is incorrect. A fraction is considered irrational if it cannot be expressed as the ratio of two integers. In the case of 1/3, it can be expressed as the division of the integer 1 by the integer 3, so it is a rational number. The fact that the decimal representation of 1/3 (0.333...) does not terminate does not make it irrational. Irrational numbers are decimal numbers that do not repeat or terminate, such as π (pi) and √2 (the square root of 2).

Answer:
Baltimore is the most populous city in the state of Maryland. The city is located in the center of the state, next to the Patapsco River, which empties into the Chesapeake Bay.
Baltimore has a humid subtropical climate, according to the climatic classification of Köppen.
July is the hottest month of the year, with an average of maximum temperatures of 91 ° F and 73 ° F of average low temperatures. The summers are very humid in the Baltimore area. The maximum temperatures registered were of 107 ° F in 1985. On the other hand, January is the coldest month, with average temperatures of 44 ° F maximum and 30 ° F of minimum temperatures. However, winters may present gusts of warm winds that soften temperatures to the point of enjoying spring periods and Arctic winds cause the collapse of temperatures, especially at night. The lowest temperature registered in Baltimore was -7 ° F, in 1934 and 1984. Due to the heat island effect in the city and a moderate effect of the Chesapeake Bay, the external and internal parts of the Baltimore metropolitan area are usually colder than the city itself and the coastal cities.
The average high temperature of Baltimore in each month is:
-January: 44º F
-February: 47º F
-March: 57º F
-April: 68º F
-May: 77º F
-June: 86º F
-July: 91º F
-August: 88º F
-September: 81º F
-October: 70º F
-November: 59º F
-December: 49º F

The partial pressure of CO in a home with air containing 6.2 ppm CO, when the total air pressure is 695 torr, can be calculated by (6.2 ÷ 1,000,000) x 695, which equals 4.3 x 10^-3 torr.
The partial pressure of a gas is the individual pressure contribution a single type of gas makes to the overall pressure of a gas mixture. In this case, a sample of air from a home was found to contain 6.2 parts per million (ppm) of carbon monoxide (CO). To calculate the actual pressure of CO in the room, we can use the fact that 1 ppm = 1 part of the substance per 1,000,000 parts of air.
To do so, we need to multiply thetotal pressure of the air, which is 695 torr, by the ratio of the CO to the total volume of the air. That would be: (6.2 ÷ 1,000,000) x 695 = 4.3 x 10-3 torr. Hence, that is how 4.3 x 10-3 is derived as the partial pressure of CO in this context.
