Answer:
degree measure = 360° × percent of data
Step-by-step explanation:
The ratio of the degree measure of a sector of a circle graph to 360° is the same as the ratio of the represented data to the whole amount of data.
The idea of a circle graph is that the area of the sector is proportional to the data being represented. That is, if the data represented is 10% of the whole, then the sector area is 10% of the whole. Sector area is proportional to the degree measure of its central angle, so the example sector would have a central angle of 10% of 360°, or 36°.
The ratio of the central angle of the sector to 360° is the same as the percentage of data that sector represents.
Answer:
0.024h
Step-by-step explanation:
We have the equation:
t 10 + t 15 = 0.6
<=> 25t = 0.6
<=> t = 0.024
It means that, it takes 0.024h for two people to complete 60% of the task
I hope it will find you well.
Let x be that number.
Let's create a system using what we have:
x^2 = 1/4 (1)
x+x = 1 (2)
In the equation (1):
x^2 = 1/4
So x = √1/4 = 1/2 OR x = -√1/4 = -1/2
Since the answer in the second equation is positive, so the acceptable answer is x = 1/2.
So the number that multiplies to be 1/4 but adds to be 1 is 1/2.
You can re-check your answer (very important):
x^2 = (1/2)^2 = 1/4
x+x = 1/2 + 1/2 = 1
The answer has been approved.
Hope this Helps! :)
Answer:
Let's simplify step-by-step.
8.3+3.4y−0.5(12y−3)
Distribute:
=8.3+3.4y+(−0.5)(12y)+(−0.5)(−3)
=8.3+3.4y+−6y+1.5
Combine Like Terms:
=8.3+3.4y+−6y+1.5
=(3.4y+−6y)+(8.3+1.5)
=−2.6y+9.8
Answer:
=−2.6y+9.8
