Answer:
150 7th Graders and 200 8th graders
Step-by-step explanation:
Basically, add the parts of the ratio together and create 7. Then, to find out how much 1 part is equal to, divide the amount of students by the number of parts - so it would be like 350/7 = 50.
So now you know that 1 part is equal to 50 students. From here, you can multiply the two amounts of parts by 50.
3 x 50 = 150 7th Graders
4 x 50 = 200 8th Graders
The answer is 0.14 since it’s out of 100
The slope formula is
. For the two points,
. You can pick any of the Y and X from these two points, but only once.
=
= 2 or
=
= 2 and both will equal to. The answer for the slope is 2.
If B is a complement of A this means that the sum of the measures of A and B is 90 degrees.
mA + mB = 90
mB =90 - mA
mB = 90 - 40 = 50
Thus, the measure of angle B is 50 degrees.
If C is a supplement of B then, the sum of the measures of B and C is 180 degrees.
mC + mB = 180
mC = 180 - mB
mC = 180 - 50 = 130
Therefore, the measure of angle C is 130 degrees.
