Answer:
0.5 seconds
Step-by-step explanation:
On the ground, height is 0
-16t² + 4 = 0
16t² = 4
t² = 4/16
t² = ¼
t = ½
Answer:
8=41
7=49
10=41
9=49
Step-by-step explanation:
angle 8 is given and since 7 and 8 make 90 then 7 =49 because 90-41=49. 10 and 8 are the same size (at least it looks like it) therefore 7 and 9 are the same too. So that is how I got the answers.
Answer:
16 students
Step-by-step explanation:
144 students enter a spelling bee contest.
Step 1
For the semi final round we are told that only 1/6 of the group will make it into that round.
This is calculated as
1/6 × 144/students = 24 students.
This means that only 24 students would make it into the semi final rounds.
Step 2
We are also told in the question that only 2/3 of THAT group would make it into the final round.
" THAT" group been referred to in the question means the number students that made it to the semi final round
This is calculated as
2/3 of that group( the group that made it to the semi finals)
= 2/3 × 24 students
= 16 students.
Therefore, the number of students that will enter the final round of the spelling bee is 16 students.
Answer:
Try 31 degrees/ Hard to explain but try it
Step-by-step explanation: cause between angle a, c, b - and angle a, o , c - their is an intersect. on that intersect onside is 62 degrees and the other side is 118 degrees; now thats a 180 degrees angle cause the base of the intersect is straight. Now this intersect is connected to the obtuse angle of the bottom triangle which is 118 degrees. Knowing that you can figure out the other corners of the traingle. The last two acute angles of to be congruent.
