Answer: 50 students
Step-by-step explanation:
You know that the number of students last year plus 20% of that number equals the number of students this year, which can be written as: x + 0.2x = 60 →
1.2x = 60 → x = 50 students :)
I'd say 13, hope this helps
Step-by-step explanation:
Answer:
Each print costed $1.92.
Step-by-step explanation:
First you'll need to divide 25 and 13
Equation: 25/13= 1.92307692
Well remove all the numbers after the number 92. and you'll get that 92.
So the answer is $1.92.
It would be) 157.25 miles (:
Hope that helps! (:
Answer:
10.50°C
Step-by-step explanation:
Given x = 2 + t , y = 1 + 1/2t where x and y are measured in centimeters. Also, the temperature function satisfies Tx(2, 2) = 9 and Ty(2, 2) = 3
The rate of change in temperature of the bug path can be expressed using the composite formula:
dT/dt = Tx(dx/dt) + Ty(dy/dt)
If x = 2+t; dx/dt = 1
If y = 1+12t; dy/dt = 1/2
Substituting the parameters gotten into dT/dt we will have;
dT/dt = 9(1)+3(1/2)
dT/dt = 9+1.5
dT/dt = 10.50°C/s
Hence the rate at which the temperature is rising along the bug's path is 10.50°C/s
