1+1= 2
Big brain >:3 Ty for the points tho ^^
Answer: it would take her 15 hours to read 400 pages
Step-by-step explanation: 400 devided by 80 is 5 and 5 x 3 = 15 hours
Let
rA--------> radius of the circle A
rB-------> radius of the circle B
SA------> the area of the sector for circle A
SB------> the area of the sector for circle B
we have that
rA=5/2 ft
rB=9/2 ft
rA/rB=5/9-----------> rB/rA=9/5
SA=(25/36)π ft²
we know that
if Both circle A and circle B have a central angle , the square
of the ratio of the radius of circle A to the radius of circle B is equals to
the ratio of the area of the sector for circle A to the area of the sector for
circle B
(rA/rB) ^2=SA/SB-----> SB=SA*(rB/rA) ^2----> SB=(9/5) ^2*(25/36)π--->
<span>SB----------- > (81/25)*(25/36)------ > 81/36------
> 9/4π ft²</span>
the answer is
<span>the measure of the sector for circle B is (9/4)π ft²</span>
The chart that could be used to display the data is D. Circle graph because the data is numerical
<h3>What is a circle graph?</h3>
A circle graph, also known as a pie chart, is a circular statistical visual that is divided into slices to demonstrate numerical proportion. In a pie chart, the arc length of each slice is proportional to the quantity shown. A pie chart is a graphical representation of data that takes the form of a circular chart or pie, with the slices representing the magnitude of the data. A list of numerical variables as well as category categories is required to represent data in the form of a pie chart.
A circle graph, also known as a pie chart, is a type of graph that is used to visually represent information and statistics. A circle graph is commonly used to demonstrate a study's proportionate outcomes. The arcs of a circle graph are proportional to the percentage of the population who responded to a specific question.
In this case, it can be used to show the students' grade points. Finally, D is the correct answer.

The 3:2 ratio can be calculated by dividing the total by the sum of the factors (3 + 2) i.e. 80/5 = 16
<span>Then multiply the factors by the answer above (i.e. 3 x 16 and 2 x 16) </span>
<span>48:32
hope this helps you ! =')</span>
