Answer:
Step-by-step explanation:
Let the total number of votes to choose a color = x
Number of votes for blue =
Remaining votes = x -
=
=
Votes for green =
=
=
Finally remaining votes =
=
=
=
Since these votes are for red therefore,
= 48
x = 48×6
= 288
a) Votes for blue are
Therefore, exact number for blue votes =
= 5×36
= 180
b). Votes for green =
=
= 60
c). Since 25 students were absent on that day of the vote, number of students at Riverside Elementary School = 288 + 25
= 313
d). Since seven tenths of the votes for blue were made by the girls.
Therefore, number of girls voted for blue =
= 7×18
= 126
Since total votes made = 288
Therefore, half of the votes made =
= 144
Now it's clear that number of votes made by girls is less than half of all the votes.
e). 126 girls voted for blue.
Answer:
C.) 14
Step-by-step explanation:
Look at the triangle: angles b and c have the same arch, so they are congruent.
In a triangle, if two angles are congruent, then the triangle is isosceles, having two equal sides.
The sides opposite the congruent angles are congruent:
∠B → opposite side → AC
∠C → opposite side → AB
The sides AB and AC are equal. Make an equation:
Simplify the equation, solving for x. Add 7 to both sides:
Subtract 2x from both sides:
The value of x is 7. Insert the value of x into the given length of AC:
Simplify multiplication:
Subtract:
Therefore, the length of the line segment AC is 14.
