21. Line p passes through Point (-4,1) and has a slope of 5 What is the equation of Line p in standard form?
A)2x - 5y = 22
B)2x - 5y = - 13
C)5x - 2y = 13
D) 5x - 2y = -22
Answer:
Step-by-step explanation:
Point( -4 , 1) ; slope = m = 5
Point-slope form:
y - y1 = m(x -x1)
y - 1 = 5(x - [-4])
y - 1 = 5(x + 4)
y - 1 = 5x + 5*4
y - 1 = 5x + 20
y = 5x + 20 + 1
y= 5x + 21

Aiden has 56 orange slices to share equally with 6 friends. If Aiden also gets an equal number of orange slices, how many orange slices will each person get?
Answer:
8 orange slices
Step-by-step explanation:
The total number of persons = Aiden + 6 friends = 7 persons
7 people are to share 56 orange slices equally.
Hence,
7 persons = 56 slices
1 person = x
Cross Multiply
7x = 56 × 1
x = 56/7
x = 8 slices
Therefore, each person will get 8 orange slices
The ratio of the number of games won to the number of games lost (no ties) by the Middle School Middies is
11/4. To the nearest whole percent, what percent of its games did the team lose?
Answer:
27%
Step-by-step explanation:
The ratio means that for every 11 games won, 4 are lost, so the team has won 11x games, lost 4x games, and played 15x games for some positive integer x. The percentage of games lost is
4x / 15x * 100 = 4/15 * 100 = 26.6666 = 27%
A percentage is a way to describe a part of a whole. To the nearest whole percentage, the percentage of games lost by the team is 27%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given the ratio of the number of games won to the number of games lost is 11/4, therefore, the total number of games played by the team is 15(11+4).
Now, the percentage of games lost by the team is,
4/15 × 100% = 26.6667% ≈27%
Hence, To the nearest whole percentage, the percentage of games lost by the team is 27%.

Seth bought glow-in-the-dark stars to
put on his ceiling. There are 5 big stars
and 25 little stars. He wants to make
constellations that each have 1 big
star. If he uses the same amount of
stars for each constellation, how many
little stars will each have?
Answer:
Each constellation will have 5 little stars.
Step-by-step explanation:
First, let's organize the information we have:
5 big stars25 little starsEach constellation should have 1 big starEach constellation should have the same amount of starsNow, let's solve the problem:
Each constellation should have 1 big star, and Seth has 5 big stars, so we can infer that there would be 5 constellations.Since each constellation have 1 big star, and the amount of stars in each constellation is the same, the amount of little stars in each constellation are the same.We have 25 little stars, and there are 5 constellations; 25 ÷ 5 = 5, so each constellation have 5 little stars.A publisher sells

There are 8 oranges, 5 apples, and 6 bananas In the fruit basket.
-Bob says the ratios of apples to bananas is 5:6
-Rob says the ratios of bananas to apples is 6:5
-Thob says that the ratios of apples and bananas to all the fruit is 11:19
Who is correct? I REALLY need an explanation.
Step-by-step explanation:
all of them are correct
there are 5 apples and 6 bananas
there are 6 bananas and 5 apples
5 apples plus 6 bananas=11
8 oranges+5 apples+6 bananas=19
so the ratio is 11:19
Answer:
they are all correct
Step-by-step explanation:
a ratio is a comparison saying that for every group of numbers that there will be another group of numbers for example
the ratio of apples to bananas is
number of apples->5:6<- number of bananas
so of the ratio stays the same then for every 5 apples added to the basket then 6 bananas will also be added(works other way to)

How do you decide what numbers to use as the numerator and the denominator in each equivalent fraction to the given decimal?
Answer:
For denominator the number of digits after the decimal are counted to find the multiple of 10s.
The numerator is the decimal number digits with the decimal removed.
Step-by-step explanation:
The given number of the decimal is used as the numerator and the denominator of the decimal always has to be 10 or a multiple of 10 depending on the position of the decimal point.
For example if we have a number 4.3
The numerator will be 43( the decimal is removed) and the denominator will be 10 because in the original decimal number 4.3 the decimal was before only 1 number that is 3.
Now take the example of 4.36
The numerator will be 436 ( the decimal is removed) and the denominator will be 100 ( 10 *10 = 100) because in the original decimal number 4.3 the decimal was before 2 number that is 3 and 6.
so the fraction will be 436/100
Now if we divide 436 by 100 we will get the same answer as the original number
100√436 4.36
400
360
300
600
600
xxx
The same process is applied to bigger numbers such as 4.365 and so on.
If we have a number 43.6 the numerator will be 436 ( the decimal is removed) and the denominator will be 10 because in the original decimal number 43.6 the decimal was before 1 number that is 6.
so the fraction will be 436/10
If we have a number 436.5 the numerator will be 4365 ( the decimal is removed) and the denominator will be 10 because in the original decimal number 436.5 the decimal was before 1 number that is 5.
so the fraction will be 4365/10
For denominator the number of digits after the decimal are counted to find the multiple of 10s.
The numerator is the decimal number digits with the decimal removed.
Tucker goes to bed at 8:25 pm every
night. He wakes up at 6:45 am. How
long does Tucker sleep each night?
Answer:
10 hours and 20 minutes.
Step-by-step explanation:
We can find out how many hours of sleep Tucker gets every night by counting in one-hour intervals.
One hour from 8:25 is 9:25.
9:25, 10:25, 11:25, 12:25, 1:25, 2:25, 3:25, 4:25, 5:25, 6:25.
This is 10 hours.
Now we count in ten-minute intervals to get to 6:45
6:35, 6:45.
This is 20 minutes.
Therefore, Tucker gets 10 hours and 20 minutes of sleep each night.
This is equivalent to 620 minutes.
===================================================
Explanation:
The user purrugh has a great answer. I'll provide a slightly different approach.
The timespan from 8:25 PM to 9:00 PM is 35 minutes. Note how adding 35 minutes to 25 past the hour gets us to 25+35 = 60 minutes, so we're at the top of the hour now, and at 9 o' clock on the dot.
Then from 9 PM to 12 midnight is a gap of 3 hours (because 12-9 = 3). From midnight to 6 AM is another 6 hours. So far we have 3+6 = 9 hours, plus the additional 35 minutes mentioned earlier. The duration so far is 9 hours, 35 minutes. We still have to account for another 45 minutes, since we want to get to 6:45 AM and not 6:00 AM.
Note how 35+45 = 80, which is over 60. This means 35 min + 45 min = 80 min = (60 min) + (20 min) = 1 hr, 20 min
That "1 hr, 20 min" is added onto the "9 hours" from earlier and we arrive at 10 hours, 20 minutes as the final answer
-----------------------------
Yet another approach is to do everything in minutes, and then convert to hours,minutes format at the very end.
Again the gap from 8:25 PM to 9:00 PM is 35 minutes. From 9 PM to midnight is 3 hours, or 3*60 = 180 minutes. We have a duration so far of 35+180 = 215 minutes.
From midnight to 6 AM is 6*60 = 360 minutes. The duration has been updated to 360+215 = 575 minutes. Finally, from 6 AM to 6:45 AM is the last gap of 45 min to get us to 575+45 = 620 minutes.
Tucker slept a total of 620 minutes. Let's convert that to hours,minutes format. Note how 620 = 600+20 and how 600/60 = 10. Meaning that 600 minutes = 10 hours. Therefore,
620 min = (600 min) + (20 min) = 10 hours, 20 minutes
