Ask a math problem!! One more math problem!!

1 part of blue flower, 2 parts of yellow flower, 3 parts of safflower, blue flower accounts for 1 6 of the total area, yellow flower accounts for 1 3, and safflower accounts for 1 2

Total area: divided by 2) square meters.

Blue and yellow flowers. Safflower will use a calculator to calculate it yourself.

The total area is (35 2).

Set the blue flower area to x square meters.

2x+3x+x=π（35/2）²

The solution is x=(35 24), that is, the area of the blue flower is (35 24) yellow flowers, and the red flowers are obtained in turn.

So the area of the blue flower is:

The area of yellow flowers is.

The area of safflower is.

Set the blue flower occupies an area of x square meters.

Then the yellow flower is 2x, and the red flower is 3x

x+2x+3x=π(35/2)²

Just solve x.

Start by calculating the area of the circular flower bed.

Let the area of the blue flower be x

The area of the yellow flower is 2x

The area of safflower is 3x

x+2x+3x=area of a circular parterre.

Solve x and figure out how many square meters each color flower occupies.

Problem description: The inner angle of a polygon increases by the same number of degrees from small to large, where the smallest angle is 100 degrees, and the largest angle is 140 degrees, find the number of sides of this polygon.

Analysis: Sum of the outer angles of the polygon = 360 degrees.

Maximum outer angle = 80 degrees.

Minimum outer angle = 40 degrees.

80+40）*x/2=360

x=6, so the polygon is a 6-sided polygon.

Step 1: How many female academicians are there?

Step 2: Seek the percentage of female academicians in the number of academicians.

Columnar calculation: (1263-1185) 1263*100%.

The first step is how many female academicians are and then the number of female academicians is used to remove the total number of academicians.

The first step is to ask for the number of female academicians The second step is to ask for the percentage of female academicians.

The first step is to find the percentage of male academicians, and the second step is to ask for the percentage of female academicians.

Don't tell me you don't know yet.

1263-1185 asked for the number of female academicians.

1263 (1263-1185) What percentage of the number of female academicians are among the number of academicians?

If there are x boys, then there are x 10 28 girls.

x ten (1-25%) (x ten 28) = 42

4x ten 3x ten 84 = 168

x = 1212 ten (12 ten 28) = 52 people.

There are x number of male students and x + 28 female students.

x+28)(1-25%)=42

x+28)=42×4/3

x+28=56

x=28 students who participated in the competition shared.

28 + 28 + 28 = 84 people.

Let the boy be x and the girl be x+28

x+(x+28)25%=42

x=28 total: 28*2+28=84 people.

There are x boys and x+28 girls. The winning girls are (x+28)*(3 4). The number of winners is total.

x+(x+28)*(3 4)=42, so x=12A total of 12+28+12=52 participated

If all are positive integers, and a is greater than 7 under the root number, and b is less than the cubic root number 2, then the minimum value of a+b is (b).

a+b=3+1=4
