Answer:
Circle graphs
A circle is the same as 360°. You can divide a circle into smaller portions. A part of a circle is called an arc and an arc is named according to its angle.
A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.
Length is always measured in linear units. Angles may be measured in a variety of units, including degrees.
Selection A is appropriate.
Hello,
Let's
V1 the velocity of the 1st bricklayer,
V2 the velocity of the 2nd bricklayer,
1wall=V1*6==>V1=w/6
1wall=V2*4==>V2=w/4
==>V1+V2=w/6+w/4=10w*24=5w/12
Let's t the time for the 2 bricklayer to build the wall
(V1+V2)t=w
==>5w/12*t=w
==>t=12/5 (h)=2h24min.
Answer:
9a^2 + 42a + 49
Step-by-step explanation:
expand to (3a+7) (3a+7) then distribute then combine like terms
