2x+8y=74
3x - 4y = 43

Answers

Answer 1

Answer:

y=17/7

x=123/7

Explanation:

2x=74-8y

x=(74-8y)/2

x=2(37-8y)/2

x=37-8y

3(37-8y)-4y=43

111-24y-4y=43

111-43=24y+4y

68=28y

y=68/28

y=17/7

x=37-8(17/7)

x=37-136/7=(37*7-136)/7=(259-136)/7

x=123/7

Answer 2
(2x+8y)/2=74/2

x+4y=37

x=37-4y

3(37-4y)- 4y=43

117- 12y- 4y =43

-16y= 74

y=4.625

x=37- 4(4.625)

x= 37- 18.5

x= 55.5

so y=4.625,x=55.5

Answer:

A- a description of the locale to a broader discussion of principles.

Explanation:

In this text, we see that the author is taking a walk when he encounters an old woman in his path. As he meets the woman, he discovers that she is a local, and wanting to lean more about the culture he is in, they engage in a conversation about the setting they are in and the local culture. This superficial description of the setting leads to a broader discussion of more philosophical principles, particularly on the subject of economy.

D) English, math, and humanities

Answers

'Evidence-base reading, writing and language and maths' includes in PSAT.

Option: C

Explanation:

PSAT- Preliminary Scholastic Aptitude Test is a rehearsal test for the students who are willing to take a SAT to get into a college with a scholarship. This test consists of two sections- Evidence Based reading, writing and language and mathematics. The reading test has 47 Multiple choice Questions for which the time limit is 60 minutes that includes comprehension, command of evidence, analytical skills and vocabulary in context. Then, comes the writing and language test which has 44 Multiple choice Questions with 35 minutes time limit, which consists vocabulary in context, tests grammar and editing skills of a student. At last, the mathematics section 48 questions in which most are Multiple choice Questions and others are solvable problems; it has a time limit of 70 minutes and contains geometry, tests algebra I and II, and some trigonometry questions.

Explanation:

The winds in a microburst are _______. If a tornado causes considerable damage with wind speeds of 111 to 135 miles per hour, it is classified as _______ on the Enhanced Fujita Scale. This type of major storm is called a/an _______, and it is driven primarily by the Coriolis effect. The weather pattern that stays over one area for an extended period of time is known as _______. Respond to the following based on your reading. What are the two types of downbursts, and how are they different? How is a funnel cloud different from a tornado? List the various stages in the formation of a tropical cyclone or hurricane, in order. Why does a hurricane begin to dissipate after it makes landfall? Explain how the heat index and the wind chill index are similar and different. What type of severe weather prevents sweat from evaporating to cool down bodies?

Answers

Answer:

1.straight

2.EF-2

3.hurricane/tropical cyclone

4.recurrent weather

5.heat wave

6.The two types of downbursts are macrobursts and microbursts. A macroburst affects an area that's greater than 2.5 miles across. A microburst affects an area that's less than 2.5 miles across.

7.A funnel cloud forms as a spinning column of air that descends from a thundercloud. However, a funnel cloud doesn't become a tornado until it actually touches the ground. Once it touches the ground, where it begins to pick up dust and debris, it becomes a tornado.

8.The stages of tropical cyclone, or hurricane, formation are 1) tropical disturbance, 2) tropical depression, 3) tropical storm, and 4) tropical cyclone.

9.Tropical cyclones, such as hurricanes, are fueled by warm ocean waters. Once they make landfall, they lose this fuel source and begin to lose strength.

10.The heat index and the wind chill index are similar because both consider other factors that affect how air temperature feels. The heat index considers relative humidity in relation to air temperature. Higher humidity makes air temperatures feel hotter. The wind chill index considers wind speed in relation to air temperature. Higher wind speeds make air temperatures feel colder.

The two types of downbursts are macrobursts and microbursts. A macroburst affects an area that's greater than 2.5 miles across. A microburst affects an area that's less than 2.5 miles across.

A funnel cloud forms as a spinning column of air that descends from a thundercloud. However, a funnel cloud doesn't become a tornado until it actually touches the ground. Once it touches the ground, where it begins to pick up dust and debris, it becomes a tornado.

Tropical cyclones, such as hurricanes, are fueled by warm ocean waters. Once they make landfall, they lose this fuel source and begin to lose strength.

The heat index and the wind chill index are similar because both consider other factors that affect how air temperature feels. The heat index considers relative humidity in relation to air temperature. Higher humidity makes air temperatures feel hotter. The wind chill index considers wind speed in relation to air temperature. Higher wind speeds make air temperatures feel colder.

Heat waves—Heat waves can be very dangerous when accompanied by high humidity. The human body depends on evaporation of sweat to cool itself down on hot days. When humidity levels are high, the rate of evaporation slows down. Consequently, it becomes harder for the body to cool itself and much easier for the body to overheat.

A copy machine makes 32 copies per minute. How long does it take to make 184 copies?

Answers

Answer:

5.75 mins

Explanation:

184/32=5.75

Final answer:

It takes 5.75 minutes, or slightly over 5 minutes and 45 seconds, to make 184 copies on a machine that makes 32 copies per minute.

Explanation:

To calculate the time needed to make 184 copies with a copy machine that makes 32 copies per minute, you perform a division operation. Divide the total number of copies (184) by the number of copies made per minute (32).

184 ÷ 32 = 5.75 minutes.

This means it takes 5.75 minutes to make 184 copies. However, in practical scenarios, a copy machine cannot make a fraction of a copy so the total time will be just slightly over 5 minutes and 45 seconds as you can't have part of a minute in actual timing.
