In isosceles triangle QRS, RT is the angle bisector of ∠QRS. Mikah begins the proof by stating ∠1≅∠2. What is a valid reason for this statement? Please HELP ME!
A. Definition of Angle Bisector
B. Reflexive Property of Congruence
C. Symmetric Property of Congruence
D. Corresponding angles are congruent.
Answer:
its a
Step-by-step explanation:
Segment RT bisects ∠QRS in ΔQRS and therefore, the angles ∠1 and ∠2
formed are equal.
The valid reason for the statement ∠1 ≅ ∠2 is; A. Definition of Angle Bisector.
Reasons:
The information on the triangle ΔQRS are;
The angle bisector of ∠QRS = RT
Therefore;
∠QRT = ∠1, ∠SRT = ∠2 Given in the diagram
∠QRS = ∠QRT + ∠SRT by angle addition property
∠QRT ≅ ∠SRT by definition of angle bisector
∠1 ≅ ∠2 by definition of ∠QRT and ∠SRT
By substituting ∠QRT with ∠1 and ∠SRT with ∠2, we have;
∠1 ≅ ∠2 by definition of angle bisector
The valid reason for the statement is therefore; A. Definition of angle
bisector.

Li bought his dog Spot a huge bone that is 15 inches long. Spot chews 4 inches off the bone every day. What is the new length of the bone after 3 days?
Answer:
3 inches
Step-by-step explanation:
If the dog chews off 4 inches every day, you first have to multiply the inches by the number of days, which in this case is 3 x 4, which equals 12. In 3 days, he chewed off 12 of the original 15 inches, leaving only 3 inches left.

The students at Plymouth South and the students at Plymouth North both planned trips to Six Flags. The students at South rented and filled 2 vans and 11 buses with 674 students. North rented and filled 6 vans and 14 buses with 882 students. Each van and each bus carried the same number of students. Find the number of students each van and In each bus. (Write your answer as an
Answer:
Number of vans = 7 students
Number of buses = 60 students
Step-by-step explanation:
Let
Number of vans = x
Number of buses = y
2x + 11y = 674 (1)
6x + 14y = 882 (2)
Multiply (1) by 3
6x + 33y = 2,022 (3)
6x + 14y = 882 (2)
Subtract (2) from (3)
33y - 14y = 2,022 - 882
19y = 1,140
y = 1,140 / 19
= 60
y = 60 students
Substitute y = 60 into
2x + 11y = 674 (1)
2x + 11(60) = 674
2x + 660 = 674
2x = 674 - 660
2x = 14
x = 14/2
= 7
x = 7 students

Answer:
1. no, 2. yes
Step-by-step explanation:
You need to use the triangular inequality thereom, which goes by if any side lengths are added together, they are greater than the remaining one. So, for number one, although 20+9=29>8 and 20+8=28>9, 9+8<20 since 9+8=17, which is less than 20. For number two, yes because 1) it is a right triangle triple and 2) 3+4=7>5, 4+5=9>3, and 5+3=8>4.
Answer:
Number 1 is Not a triangle so No and you don’t need to classify becuase it’s not aa triangle
Number 2 is a triangle becuase its ta Pythagorean triplet and even if you checK, it adds up.
Step-by-step explanation:
1) So using Pythagorean Theorem
8^2+9^2=20^2
64+91=400
That is not true
2) 3^2+4^2=5^2
9+16=25
That is true

4. Emilio asks his classmates what month they were born. He finds that 15
out of 125 classmates were born in July. If there are 1,280 students in
Emilio's school, how many students can he expect to have birthdays in July
based on the experimental probability?
Ok
Answer:153
Step-by-step explanation:
From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.
If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:
= 3/25 × 1280
= 153.6
There will be 153 students expected

Which of the equations are true identities? \begin{aligned} \text{A. }&(y+6)(y-7)+42=y^2-y \\\\ \text{B. }&(x+3)(x-8)=x^2-5x \end{aligned} A. B. (y+6)(y−7)+42=y 2 −y (x+3)(x−8)=x 2 −5x
Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.

The coach recorded how fast her runners ran 1 mile. Eric ran a mile in 10.84 minutes, Kay ran a mile in 12.79 minutes, and Rosie ran a mile in 9.58 minutes. How many more minutes did Eric run than Rosie?
Answer:
1.26 minutes
Step-by-step explanation:
The runners all ran the same distance of 1 mile.
Eric's time to run 1 mile = 10.84 minutes
Kay's time to run 1 mile = 12.79 minutes
Rosie's time to run 1 mile = 9.58 minutes
This implies that Rosie is the fastest runner among the three.
The difference between Eric and Rosie's time = Eric's time - Rosie's time
= 10.84 - 9.58
= 1.26
The difference between Eric and Rosie's time shows the minutes Eric ran more than Rosie. Therefore, Eric ran 1.26 minutes more than Rosie.

There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth graders.
How many band members are sixth graders?
Answer:
28 band members
Step-by-step explanation:
Since 40% of the band members are sixth graders, we need to take 40% of 70 total students.
40% of 70 = 0.40*70 = 28
So 28 band members are in sixth grade

Cecilia's mom ordered pizza for dinner. The pizza has two slices of pepperoni, two slices of mushroom, and two slices of anchovy. Cecilia asks her brother to bring her two slices. List all the possible combinations where the first choice is pepperoni.
Answer:
If the first slice is pepperoni, then we have left:
1 slice of pepperoni.
2 slices of mushrooms.
2 slices of anchovy.
Then the possible combinations are:
Pepperoni and pepperoni (in only one combination)
Pepperoni and mushrooms (in two combinations, because there are two slices left)
Pepperoni and anchovy (Again in two combinations, because there are two slices left)
These are the 3 possible combinations, 5 in total.
