The owner of a small restaurant bought 75 kilograms of rice. Each week, the restaurant uses 4.5 kilograms of rice.
Function `r` gives the remaining amount of rice, in kilograms, as a function of the number of weeks since the restaurant owner bought the rice.
Solve the equation `r(w)=30`and explain what the solution means in this situation.
Answers
Answer:
r(t) = 75 kg - (4.5 kg/wk)w
Step-by-step explanation:
Let r(t) represent the amount of rice remaining after w weeks.
Then:
r(t) = 75 kg - (4.5 kg/wk)w
please mark as brainliest
Answer:
w=10 and this means that 10 weeks after the rice was bought, 30 kilograms of rice remain.
Step-by-step explanation:
r(w)=75-4.5w is an equation for this function so I'll be using this. First insert r(w)= 30 into the equation.
75-4.5w=30
75-75-4.5w=30-75
-4.5w=-45
-4.5w/-4.5 = -45/ -4.5
w=10
Apologies if the explanation isn't thorough, I'll glady provide more details if necessary.

Answers
Answer:
1 inch³
Step-by-step explanation:
Why, why does it have to be an inch, alright. So, you have to find the area of one side and multiply it by the length, the catch is that it's all 1, so 1 x 1 x 1 = 1, so your answer is the cube's length is 1 inch³

Step-by-step explanation: if there are 500 pieces of paper and the entire stack is 1.875 inches tall, you devide the total height by 500. I know Deigo is wrong because you can easily reverse check his work by multiplying 0.015 by the total number of papers 500 you will get 7.5 which is not the height of the stack
1.875/500=0.00375
each piece of paper is 0.00375
Which of the following allows you to compare the frequency of intervals, but not the frequency of exact values?
A.a dot plot
B.a stem-and-leaf plot
C.a histogram
D.a circle graph
Answers
The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.
What is a Histogram?An histogram is a graphical representation of a data distribution, which uses bars or bins to represent the frequency of the data distribution that are in intervals.
Similarly, in dot plot the total number of dots tells us the total number of observations of the values of that thing we did.
The Stem and leaf plot is to show the data distribution while retaining its uniqueness which shows the raw values by retaining the original data,
The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.
Therefore, the graph used to show data in intervals is: B.a stem-and-leaf plot

Charlotte recorded the number of minutes she spent exercising in the past ten days: 9, 13, 5, 2, 9, 1, 14, 3, 5, 7. Find the median of the data.
Answers
Answer:
The median is 7.
Step-by-step explanation:
In order to find the median, you need to ut the numbers in either least to greatest form, or greatest to least (FIRST).
I'm gonna do both as an example.
Greatest to least:
14, 13, 9, 9, 7, 5, 3, 2, 1
Least to greatest:
1, 2, 3, 5, 7, 9, 9, 13, 14
It is REALLY important that you use ALL of the numbers you are given, even if there are two or more of the same number.
The next thing you need to do is find the number that is in the middle.
It will be the same for both least to greatest AND greatest to least.
You can either count one from either side, going in a pattern, OR you can count how many there is, divide it by 2, and whatever answer you get, count that many times over from one side.
In this case, your answer goes like this:
since there are 9 numbers, and 9 is not an even number, you will have only one median. Having 2 medians IS normal and it IS ok.
In this case, you want to go down one number (from 9) and divide that. So you do 8 divided by 2, which is 4. Count that many times over and you have your answer, 7.
I hope this helped you!

How much would they make in a half hour if they worked together?
Answers
Answer:
4/9 and 8/9
Step-by-step explanation: you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer

Answer:
1 7/8 ounces
Step-by-step explanation:
Simple addition:
1/8 + 1/8 = 2/8 = 1/4
1/4+ 1/4 = 2/4
3/8 + 3/8 = 6/8 = 3/4
2/4 + 3/4 = 5/4 = 10/8
10/8 + 5/8 = 15/8 = 1 7/8 oz.

A rectangle has sides that are 10 m, 10m, 5m, and 5 m. What is the rectangle’s length?
5m
20 m
10 m
30 m
Answers
The way the question is worded is a little confusing.
I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)
The length of the rectangle will be 10 m.
What is a rectangle?A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
Given that, a rectangle has sides that are 10 m, 10 m, 5 m, and 5 m.
We need to find the length of the rectangle,
We have the dimensions 5 m x 10 m,
Lengths in a rectangle tells that how much the rectangle is long and the width tells how much the width tells about the breadth of the rectangle,
So, we can say that,
Length = 10 m
Width = 5 m
Hence, the length of the rectangle is 10 m.
