HELP ME PLEASSSSEE On a winter morning, the temperature before sunrise was -10℉. The temperature then rose by 1℉ each hour for 7 hours before dropping by 2℉ each hour for 3 hours. What was the temperature, in degrees Fahrenheit, after 10 hours?

Answers

Answer 1
Answer:

Answer:

3 degrees F

Step-by-step explanation:

if the temperature rose 1* for 7 hours, times 1 by 7. which is 7 and add to -10. which is -3. then, since the temperature rose by 2* for 3 hours, times 2 by 3 which is 6 and add to -3, which is 3.

i hope this helped?

Help asap please!Add 4p^2+6 / 4p^2 + 2p-2 / 10p

Which statements are true about adding the rational expressions? Check all that apply

The least common denominator is 20p
.
The first fraction rewritten with the LCD is 20p^2+30 / 20p^2

The second fraction rewritten with the LCD is 4p - 4 / 20p

The sum is 24p^2-,4p+30 / 20p^2 = 12p-2p+15 / 10p^2

The sum is a rational expression.

Answers

I have to rewrite the expressions because they look very confusing.

1) The given fractions to add are:

  4p² + 6        2p - 2
------------ +  ------------
     4p²             10p²

2) The statements to asses are:

A) The least common denominator is 20p
.
B) The first fraction rewritten with the LCD is (20p² +30) / 20p²

C) The second fraction rewritten with the LCD is (4p - 4) / 20p

D) The sum is (24p² -4p +30 ) / 20p² = (12p-2p+15) / 10p^2

E) The sum is a rational expression.

This is the result for each statement.


A) The least common denominator is 20p

FALSE: THE LCD IS 20p², because it the least expression that contains all the prime factors of both denominators: 4p² and 10p.

See that you cannot divide 20p by 4p² but you can divide 20p² by 4p² and 10 p. So, 20p is not a common denominator.
.
B) The first fraction rewritten with the LCD is (20p² +30) / 20p²

TRUE: you get this expression from the first fraction by multiplying both numerator and denominator by  20p² / 4p² = 5:

(4p² + 6)×5 = 20p² + 30

(4p²)×5 = 20p²

=>

  20p² + 30
--------------
      20p²

C) The second fraction rewritten with the LCD is (4p - 4) / 20p

FALSE: you have to multiply both numerator an denominator by 20p² / 10p = 2p

(2p - 2) × 2p = 4p² - 4p

10p × 2p = 20p²

So, the second fraction rewritten with the LCD is:

 4p² - 4p
-----------
    20p²

D) The sum is (24p² - 4p +30 ) / 20p² = (12p-2p+15) / 10p²

TRUE


  20p² + 30        4p² - 4p         24p² - 4p + 30
-------------- +   --------------- = ----------------------
      20p²              20p²                    20p²


And when you simplify the last fraction dividing by 2 you get:

  12p² - 2p + 15
-----------------------
          10p²

E) The sum is a rational expression.

TRUE:

The sum of rational number has the closure property which means that by adding rational expression you will always ge a rational expression.

Put these in order of size smallest first , 0.3 , 75% 4/5

Answers

0.3, 75%, 4/5    Convert all to decimal

0.3, 0.75, 0.80  So we can now arrange it with smallest first.

It is already in that order from the smallest to biggest.

= 0.3, 75%, 4/5
convert them to decimal
0.3, 0.75, 0.8 so it is 0.3, 0.75, 0.8. answer is 0.3 , 75%, 4/5

Decrease from 126 ounces to 48 ounces percent

Answers

Answer: There is 61.9% decrease in the value from 126 ounces to 48 ounces.

Step-by-step explanation:

Original value=126 ounces

New value = 48 ounces

Difference = 126-48 = 78 ounces

So, Percentage of decrease value is given by

(Difference)/(Original)* 100\n\n=(78)/(126)* 100\n\n=61.9\%

So , there is  61.9% decrease in the value from 126 ounces to 48 ounces.

Answer:

Decrease in percentage = 61.9%

Step-by-step explanation:

Decrease from 126 ounces to 48 ounces percent

First find out the amount of decrease. Subtract the number to find the amount of decrease

126-48=78

now find out which percentage is 78

percentage =(78)/(126)  \cdot 100=61.9

Decrease in percentage = 61.9%
