HELP ASAP PLS Billy wanted to write a ratio of the number of apples to the number of peppers in his refrigerator. He wrote : . Did Billy write the ratio correctly? Explain your answer.
Answer:
yes, Billy wrote the ratio correctly
Step-by-step explanation:
To indicate that you're using a ratio, you can use the division sign ( / ), a colon ( : ), or the word to. For example, if you wanted to say, "For every five men at the party, there are three women," then you could use any of the three symbols to state this. Here's how we go about it :
5 men / 3 women
5 men : 3 women
5 men to 3 women

Katie has a cat named
Fluffy. Fluffy eats a whole
bag of cat food in two
weeks. Katie feeds Fluffy
twice a day. The cat food
comes in a 7 cup bag.
How many
cups of food
does Fluffy
each serving?
Please show step by step
Answer:
1/2 a cup or 0.5 cups per serving
Step-by-step explanation:
If you were to divide 7 by 14 you would get 0.5. The reason as to why you would divide 7 by 14 is because if she eats twice a day that would be 7 more times then if she were to be fed once a day. So if you were to feed her twice a day that would be 14 times a week.
Don't think this helped at all but I tried my hardest, sorry if you get your problem wrong. Hope you have a good day :D

Step-by-step explanation:
The employees from a government agency were asked whether they preferred a four-day work week (10 hours per day), a five-day work week (8 hours per day), or flexible hours. You are given information on the employees' responses broken down by gender. What proportion of employees is male and not in favor of a five-day work week?
Answer:
10%
Step-by-step explanation:
Using the data provided we are given the total number of people surveyed, which means we need to now find the total number of males that are not in favor of a five-day workweek. We do this by using the total of male participants and subtracting the number of male participants that are in favor of a five-day workweek
1800 (total) - 1200 (in favor) = 600
Now we know that 600 male participants are not in favor of a five-day workweek. Now we divide this number by the total amount of participants (both male and female) in order to find the percentage.
600 / 6000 = 0.1
0.1 * 100 = 10% ... multiply by 100 to get percentage.
Therefore only 10% of male participants are not in favor of a five-day workweek.
Three hikers started climbing with each hiker carrying 7.8 kilograms of weight. A fourth hiker joined them and they divided the total weight of hiking equipment evenly. How much did each hiker have after the 4th person joined? (Round your answer to two decimal places)
Answer:
5.85 kilograms
Step-by-step explanation:
We are told that Three hikers started climbing with each hiker carrying 7.8 kilograms of weight.
Thus, total weight carried by them = 7.8 × 3 = 23.4 kilograms
Now a fourth person joined them and they divided the weight equally.
Thus, each hiker will now carry;
23.4/4 = 5.85 kilograms
Scarborough High School ordered several replacement books for the mathematics department. When the box of books arrived at the high school, it contained Algebra I, Geometry, and Algebra II textbooks. A label on the box reads: "Contents: 23 books, Weight: 93 lbs." An Algebra I book weighs 4 pounds, a Geometry book weighs 3 pounds, and an Algebra II book weighs 5 pounds. The number of Geometry books and Algebra II books combined is one less than the number of Algebra I books.
Answer:
Algebra 1 = 12 books
Algebra 2 = 5 books
Geometry = 6 books
Step-by-step explanation:
Given
Represent
Algebra 1 with A
Algebra 2 with B
Geometry with C
For the quantity
[tex]A + B + C = 23[/tex]
To represent the weight, we have that:
[tex]A = 4lb[/tex]
[tex]B = 5lb[/tex]
[tex]C = 3lb[/tex]
[tex]Total = 93lb[/tex]
This gives:
[tex]4A + 3B + 5C = 93[/tex]
The last sentence in the question can be represented with:
[tex]C + B = A - 1[/tex]
So, the expressions to work with are
[tex]A + B + C = 23[/tex] --- (1)
[tex]4A + 3B + 5C = 93[/tex] --- (2)
[tex]C + B = A - 1[/tex] --- (3)
Substitute A - 1 for B + C in (1)
[tex]A + B + C = 23[/tex]
[tex]A + A - 1 = 23[/tex]
[tex]2A - 1 = 23[/tex]
Solve for 2A
[tex]2A = 23 + 1[/tex]
[tex]2A = 24[/tex]
Solve for A
[tex]A = 12[/tex]
Substitute 12 for A in the (2) & (3)
[tex]4A + 3B + 5C = 93[/tex]
[tex]4 * 12 + 3B + 5C = 93[/tex]
[tex]48 + 3B + 5C = 93[/tex]
[tex]3B + 5C = 93 - 48[/tex]
[tex]3B + 5C = 45[/tex] ---- (4)
[tex]C + B = A - 1[/tex]
[tex]C + B = 12 - 1[/tex]
[tex]C + B = 11[/tex]
Make C the subject
[tex]C = 11 - B[/tex] ----- (5)
Substitute 11 - B for C in (4)
[tex]3B + 5C = 45[/tex]
[tex]3B + 5(11 - B) = 45[/tex]
[tex]3B + 55 - 5B = 45[/tex]
Collect Like Terms
[tex]3B - 5B = 45 - 55[/tex]
[tex]-2B = -10[/tex]
Solve for B
[tex]B = -10/-2[/tex]
[tex]B = 5[/tex]
Substitute 5 for B in (5)
[tex]C = 11 - B[/tex]
[tex]C = 11- 5[/tex]
[tex]C = 6[/tex]

Answer:
2.27%
Step-by-step explanation:
Lets start by making the names letters, J C and A respectively.
The total is 44 dollars. J paid 34%, which would be 14.96. He pays a total of $15. C paid 50%, which is 22 dollars. A pays 17%, which would be 7.48. She pays a total of $8.
15 + 8 + 22 = $45, meaning they paid an extra 1 dollar. One dollar is 1/44th of $44, or 2.27%.
Note: 2.27% is 2.272727272727 repeated, do what you will with that information, every site is different.

Step-by-step explanation:
If 2(x+3)^2=98 find x in this equation.
Answer:
x= 4 or -10
Step-by-step explanation:
Answer:
x = - 10, x = 4
Step-by-step explanation:
Given
2(x + 3)² = 98 ( divide both sides by 2 )
(x + 3)² = 49 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 3 from both sides )
x = - 3 ± 7
Thus
x = - 3 - 7 = - 10
x = - 3 + 7 = 4
A number d is at most |−5|. Graph the solution on the number line.
Answer:
Graph Inequality on Number Line
Graphing an inequality on a number line, is very similar to graphing a number. For instance, look at the top number line x = 3. We just put a little dot where the '3' is, right?
Now an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above or below it.

Write the equation of a line that passes through the point (-2,6) and is parallel to the line that passes through the points (0, – 4) and 3,2).
Answer:
Y = 9 + 2/3
Step-by-step explanation:
First, find the equation for the given points ((0, - 4) and (3, 2)). By graphing these points, I found that this equation was Y = -4 + 2/3.
Now, we can start to form the equation of the line you are trying to find. Because parallel lines must have the same slope, we know that the slope of the line will be 2/3. We can now use this slope to find the Y-intercept of the line. Add 2 to the X-coordinate and 3 to the Y-coordinate. By doing this you get the coordinates (0, 9). 9 is the slope of the second line.
Now we can make the equation you are trying to find. The answer is Y = 9 + 2/3 where 9 represents the Y-intercept and 2/3 represents the slope of the line.
Hope this helps! Let me know.
What is the proper expression for the absolute value of 3?
When we take the absolute value of a number, we always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero). For instance, | 3 | = 3, and | –3 | = 3 also.
