Answer:
diameter of semicircle? ---> 30cm
perimeter- pi*r ----> 3.14159265 x 15 ---->47.12 cm
Step-by-step explanation:
I believe it’s 3
I think that because you would do this
1-(-5)
———
5-3
Which would equal 3
In military time it would still be 7:45 am
Answer:
a 13 students
b 9 groups
Step-by-step explanation:
I will assume we want equal amounts of children from each grade
6th grade:
27 = 3*9 = 3*3*3
7th grade
36 = 4*9 = 2*2*3*3
8th grade
54 = 6*9 = 2*3*3*3
The terms that appear in each of 6th, 7th and 8th are 3*3
That is the greatest common factor
3*3 = 9
We can make 9 groups, Factor out the 9 and what is left is the number from each grade that is in each group
6th grade:
27 = 3*9 There will be 3 6th graders in one group
7th grade
36 = 4*9 There will be 4 7th graders in one group
8th grade
54 = 6*9 = There will be 6 8th graders on one group
In one group we have 3+4+6 = 13 people
There will be 9 groups of 13 children
Answer:
The line segment HK is the diameter.
Step-by-step explanation:
A straight line segment that passes through the center of the circle, and whose endpoints lie on its circumference, represents the diameter of the circle.
From the choices given, we see that two straight segments HK and GJ pass through the center of the circle, and have endpoints at the circumference. and since choice GJ is not given in the options, we choose HK as the right diameter of the circle.
<em>P.S: looking at other choices, we see that the segment GK represents the chord, JL represents the radius, and IL also represents the radius.</em>
