Answer:
455 passes
Step-by-step explanation:
If 350 is only 70% of his passes, take the remaining percentage which is 30% and multiply it to the known value of completed passes which is 350. So 350x.30= 105. Then just add 105 to 350 and you get the total number of passes. Hope this helped!
Answer:
22
Step-by-step explanation:
64+20= 84 (number of students in total)
84/2= 42 (number of students each session)
Moving 22 students to Monday will result in equal number of students.
Answer:
160 cm
Step-by-step explanation:
a square has 4 equal sides. if one of the sides is 40 cm, then all of the other sides are 40 cm as well. to get a perimeter, you add up the lengths of all the sides. if there are 4 sides of 40 cm, you multiply 40 by 4 to get 160, finally add the unit to get 160 cm.
Answer:
AA similarity
Step-by-step explanation:
Using angle sum theorem, you can clearly find out the missing angles on the left and right triangles are 40° and 50° respectively.
Therefore, by using any two angles in the triangles, you can prove they are similar by AA similarity.
We may draw a vertical that bisects the vertex angle and the shorter side of the triangle, to form a right-triangle with the measurements:
hypotenuse = 8
length = 1.5
We may then apply:
sin(∅) = P / H
sin(∅) = 1.5 / 8
∅ = 10.8 ≈ 11°
This is half of the vertex angle, so the vertex angle is:
11 * 2 = 22°
