Parabola y = quarter times x squared focal coordinate

Parabola y = quarter times x squared focal coordinate

y^2=1/4*x
So p = 1 / 8
So focus coordinates (1 / 16,0)

There are 56 students in Grade 6 of Houcun primary school, of which 37 are boys. Later, they were transferred to several male students. At this time, male students account for 715% of the class. How many male students were transferred?

56 × (1-37) / (1-715), = 56 × 47 × 158, = 60 (people); 60-56 = 4 (people). A: four male students

There are 56 students in a class, of which three out of seven are boys. Later, how many boys are transferred into the class? This is the number of boys, which is seven out of eight of the number of girls
process

The number of female students is 56 * 4 / 7 = 32
32*7/8=28
28-24 = 4 for boys

In tree planting activities, how many trees are there in Grade 7 or grade 2?

40 / (7-5) = 20 (trees) 20 * 5 = 100 (trees) 20 * 7 = 140 (trees)

In tree planting activities, how many trees are planted in each of the two grades?

There are 62 (3-1) = 62 (2) = 31 trees in grade five
In the sixth grade, 31 + 62 = 93 trees were planted

Students participate in tree planting activities, twice,

The number of trees planted in the sixth grade is 1.2 times that of the fifth grade, that is, the number of trees planted in the sixth grade is 6 / 5 of the fifth grade. The number of trees planted in the sixth grade is 1 more than that of the fifth grade, which is exactly 50
50 divided by 1 / 5 = 250

Math problem: in the tree planting activity in March, the number of trees planted in Grade 6 is 1.2 times that of grade 5, 10 less. It is known that there are 6 more trees planted in Grade 6 than in Grade 5. Ask five
Please be more detailed. Requirements: correct within 3 minutes, 30 points for you. To be right soon, to receive the equation, to solve: set... Don't tell me what x equals, you call here for the whole process, 30 points for you directly

If x trees are planted in the fifth grade and Y trees are planted in the sixth grade, then
y=1.2x-10
y=x+6
The solution is: x = 80, y = 86
A: 80 trees in the fifth grade and 86 trees in the sixth grade

In the tree planting activities in March, there were 10 trees less than twice,
In the tree planting activity in March, there are 10 trees less than twice. How many trees do the fifth and sixth graders plant each? (solve the equation)

There are x trees planted in the fifth grade
1.2X-10=X+6
1.2X-X=10+6
0.2X=16
X=80
1.2x-10 = 1.2 * 80-10 = 86 trees
A: 80 trees are planted in the fifth grade and 86 in the sixth grade

In the tree planting activities, the number of trees planted in Grade 6 is 1.2 times less than that in Grade 5. How many trees are planted in Grade 5 and grade 6?

There are x trees in the fifth grade and (x + 6) trees in the sixth grade
x+6=1.2x-10
0.2x=16
x=80
x+6=80+6=86
