It will take them exactly 4hours 48 minutes.
<h3>what is rate?</h3>
Rate is a measure of a given quantity against a known or standard quantity.
Analysis:
If Tanya and Tim cleaned the house in 3 hours. Then either of them would clean the house in 2 x 3 = 6 hours.
If their 3 children cleaned the house in 6 hours, then each child would clean the house in = 3 x 6 = 18 hours
Total time for cleaning the house = 18 hours + 6 hours = 24 hours
If the five people were to do it at once then time taken to clean the house = 24/5 = 4.8 hours = 4 hours 48 minutes
In conclusion, the time for 5 people to clean the house is 4 hours 48 minutes

To do this I must first determine what fraction of the circle is represented by the central angle 30°. Since there are 360° in a full circle, I can find the fraction of a circle by simplifying . The sector<span> represents of the circle. To find the </span>arc length<span>, I now need to find the circumference of the entire circle.

Answer:
7 red marbles
Step-by-step explanation:
P( red) = red marbles / total marbles = 1/8
We know there are 56 marbles
red marbles/56 = 1/8
Multiply by 56
red marbles = 1/8 *56 = 7
There are 7 red marbles
Answer:
There is a positive correlation between the number of hours spent on homework and the test scores. So, the more homework you do, the better your test score.
Step-by-step explanation:
The data given is representative of a scatter plot, which shows a relationship with two sets of data that, when using a line of best fit, will show either a positive correlation (increasing), a negative correlation (decreasing) or no correlation (the data shows no overall pattern). In this case, you can see that the overall pattern of data is increasing, or a positive correlation. Which means that, in general, the more hours of homework you do, the more likely you are to receive a better test score.
Answer:
Your answer would 1,548. You would multiply the two numbers, as numbers in parentheses immediately next to each with no symbol of mathematics between them means multiplication, you would just multiply them. Hope this helps!
