Answer:
Step-by-step explanation:
A) One student is chosen from Classroom A, then a student is chosen from Classroom B
the sets for each probability to happen are different. what happen in first clause is unrelated to the second clause
I think it might be 38
The first equation-
21/3=7
So spider=7
The second-
(17-7)/2=10/2=5
So hat=5
The third-
(11-5)/2=6/2=3
So bat=3
The fourth-
3+5x7=3+35=38
Answer: Either you repeat or summer school or you just get expelled

Answer:
2(28)=23+x
Step-by-step explanation:
There are 28 students and each student needs two brownies. You have to multiply 28 by 2 so you will have to total number on one side.
On the other you need to have the number of brownies you have at the moment and x for the number you need to bake. You want to add them because you will need to put those numbers together to get the number on the opposite side.
28x2=56 so 56=23+x. Subtract the 23 from both sides to get 33=x. x=33
To check plug 33 into x to get 2(28)=23+33. 56=23+33. 56=56
you need 33 more brownies.
So the equation would be 2(28)=23+x.
Hope that helps.
Answer:
6%
Step-by-step explanation:
Given,
Interest (I) = 2160
Principal (P) = 12000
Time (T) = 3 yrs
Rate (R) = ?
We know that,
R = ( I *100)/ (P*T)
= (2160*100)/(12000*3)
= 6%
therefore, the rate of interest is 6%
