There are 975 girls in the school.
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that there are 1,500 students in a school. 65% of them are girls.
We need to find the 65% of 1500.
65/100 x 1500/1
The two "zeros" in "100" cancel out and the two "zeros" in "1500" cancel out And we are left with:
65/1 x 15/1 = 65 x 15 = 975 girls.

Answer:
The larger circle area is 314 cm
The smaller circle area is 78.5 cm
Step-by-step explanation:
The formula for circles area is r^2×π
r is radius to the power or 2 then multiplied by 3.14
The big circle is 10 so 10 to the second power is 100
So 100×3.14=314
Therefore, the big circle's area is 314 cm
You do the same for the smaller circle
5 to the second power is 25
25×3.14=78.5
And for this reason the area of the smaller circle is 78.5 cm

Find the 9th term
Answer:
The ninth term would 0.25.
Step-by-step explanation:
The pattern happening here is that the number is being divided by 2.
So, continuing the pattern, continue dividing by 2.
8÷2= 4 ----> 5th term
4÷2= 2 ----> 6th term
2÷2= 1 ----> 7th term
1÷2= 0.5 ----> 8th term
0.5÷2= 0,25 ---> 9th term
Answer: x = 10
Step-by-step explanation: First, you combine like terms. Your equation is now 5x-2 = 48. Then, you isolate the variable by moving the -2 onto the other side. Now your equation is 5x = 50. Then you divide 5x by 5 to isolate x and divide 50 by 5 and get 10, so x = 10.
