It's the first one because at Jefferson middle there are 24 students to 1 teacher and all you know about Hamilton middle is 12 teachers to 312 students
24•12= 288
So Jefferson will have 12 teachers for 288 students
The multiplicative inverse of 1000/450 is 9/20
<h3>How to determine the inverse of the number?</h3>
The multiplicative inverse of a number x is:
Inverse = 1/x
The number is given as: 1000/450.
So, we have:
Inverse = 1/(1000/450)
Evaluate the expression
Inverse = 450/1000
Simplify
Inverse = 9/20
Hence, the multiplicative inverse of 1000/450 is 9/20

Answer:
x=-22/3
Step-by-step explanation:
the slant height would be the hypotenuse of a right triangle. 1/2 the length of the base would be one side of a right triangle. Use the Pythagorean theorem to find the height:
89.9^2 = 9.9^2 + x ^2
8082.01 = 98.01 + x^2
X^2 = 8082.01-98.01
X^2 = 7984
X = sqrt(7984)
X = 89.35
Round to 89.4
