We have been given that a librarian noticed that 60% of seventh graders checked out fantasy books. We are asked to find the number of seventh graders from 240 seventh graders, who would checkout fantasy books.
To solve our given problem, we need to find 60% of 240.
Therefore, 144 seventh graders would checkout fantasy books.
Answer:
1. Yes
2. No
2. Yes
4. Yes
5. Yes
Step-by-step explanation:
The angles in the first pair are congruent and 40° each (XYZ and XYW are complementary)
Segment FG is 4 cm while segment DE is 6 cm so they are not congruent
As shown on the figure both segment OR and segment OS is 2 in. long
Angle 2 and angle 4 are congruent
Angle ROQ and angle ROP are congruent because all angles shown on the figure has a measure of 90°
PART A
s = <span>the number of packets of strawberry wafers ;
c = </span><span>the number of packets of chocolate wafers ;
3 </span>× s + 1 × <span>c = 30 ;
s + c = 22 ;
PART B
</span>The method of solving "by substitution"<span> works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
</span>
c = 30 - 3s;
s + ( 30 - 3s ) = 22;
30 - 2s = 22;
30 - 22 = 2s;
8 = 2s;
s = 4 ;
c = 30 - 12 ;
c = 18 ;
Answer:
When two lines are cut by a transversal, the pairs of angles on either side of the transversal and inside the two lines are called the alternate interior angles . If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent
