Answer:
7, 10 and 15
Step-by-step explanation:
Given
--- Students already enrolled
![Total = 10\ (less)](https://tex.z-dn.net/?f=Total%20%3D%2010%5C%20%28less%29)
Required
Determine the additional number of students needed for the teacher not to cancel the class
First, we need to calculate the number of students for the teacher to cancel the class.
Represent this with x.
So, we have:
![S_1 + x < Total](https://tex.z-dn.net/?f=S_1%20%2B%20x%20%3C%20Total)
Make x the subject
![x < Total - S_1](https://tex.z-dn.net/?f=x%20%3C%20Total%20-%20S_1)
Substitute values for Total and S1
![x < 10 - 3](https://tex.z-dn.net/?f=x%20%3C%2010%20-%203)
![x < 7](https://tex.z-dn.net/?f=x%20%3C%207)
This means that if less than 7 additional students come to the class, the teacher will cancel the class.
So, for the teacher not to cancel the class, the students must be 7 or greater (i.e. 7, 8, 9, 10....)
Answer:
* 60 -$60 <- answer
* 45- $45 <- answer
94.5- $94.50 <- answer
Step-by-step explanation:
40%= 0.4 ×150=60
30%=0.3×150=45
60 +45= 105
(105*10)/100= 10.50
105-10.50=$94.50 <- answer
M = (t+1)/(t-3)
m(t-3) = t+1
mt-3m = t+1
(m-1)t = 3m+1
t = (3m+1)/(m-1)
Answer:
m∠2 = 40°
Step-by-step explanation:
Because the 2 lines are parallel, that means ∠1 and ∠2 are corresponding angles. Using the Corresponding Angles Theorem, m∠1 = m∠2. Therefore, m∠2 is 40°.
36 muffins at $2 a piece would be $72
4 cakes at $8 a piece would be $32
$32+$72= $104
