Answers

Answer 1

Answer: If you would like to know how much weed killer will Alan need for two fields, you can calculate this using the following steps:

two fields: 22 1/2 acres + 38 1/4 acres = 45/2 + 153/4 = 90/4 + 153/4 = 243/4 = 60.75 acres

4/5 of a quart = 0.8 quart ... 1 acre of land
x quarts = ? ... 60.75 acres of land

0.8 * 60.75 = 1 * x
x = 0.8 * 60.75
x = 48.6 quarts

The correct result would be 48.6 quarts of weed killer.

$6!=6*5*4*3*2*1=720.$

So, the total number of ways is 720.

Option (d) is CORRECT.

(2) Given that there are 8 girls competing in an ice-skating competition.

So, the number of ways in which they can finish in first, second, and third place is given by

$8* 7* 6=336.$

Thus, the total number of ways is 336.

Option (a) is CORRECT.

(3) The number of ways in which a president and vice president can be selected from a class of 12 is given by

$12*11=132.$

Thus, the total number of ways is 132.

Option (c) is CORRECT.

(4) The number of ways in which 7 students can line up for a class picture is given by

$7!=7*6*5*4*3*2*1=5040.$

Thus, the required number of ways is 5040.

Option (a) is CORRECT.

Pick a city in Maryland and determine the average high temperatures for eachmonth. Record this in a table.

Answers

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

One number is 4 more than another, and their sum is 60. What is the smaller number?

Answers

According to your question, there are 2 unknown numbers mentioned.Let the 2 unknown numbers be represented by the variables x & y, thenx is considered to be one of the numbers being more than y by the addition of 4, .ie.x = 4 + y --- (1)The sum of the 2 numbers is 60, i.e.x + y = 60 --- (2)To find the smaller number, we solve eqn (1) & (2) using the concept of substitution, i.e. substitute 4 + y for x in eqn (2), i.e.4 + y + y = 604 + 2y = 602y = 60 - 42y = 56y = 28 ...Ans.Recall that x is more than y by 4, then 28 is the smaller number.
