Answer:
14
Step-by-step explanation:
To evaluate the value of the expression
when
you should substitute 2 instead of e into expression. Then you will get the expression
![8+3\cdot 2.](https://tex.z-dn.net/?f=8%2B3%5Ccdot%202.)
Since
![3\cdot 2=6,](https://tex.z-dn.net/?f=3%5Ccdot%202%3D6%2C)
this expression becomes
![8+3\cdot 2=8+6=14.](https://tex.z-dn.net/?f=8%2B3%5Ccdot%202%3D8%2B6%3D14.)
72 people stayed, because 96 ÷ 4 = 24, and 24 * 3 is 72.
Step-by-step explanation:
Given the information that the scale of 1 : 60
- a. Plot a point which is 240 cm from A and is on the line AB.
Scale = 1 : 60
<=> 240 cm = 4 cm
Use a compass with the width = 4 cm and the center is point A then you draw an arc such that it intersect line AB . After that, we will have a point (the intersection point) which is which is 240 cm from A and is on the line AB
- b) Plot a point which is 240 cm from A and is on the line CD.
Scale = 1 : 60
<=> 240 cm = 4 cm
The same way in the answer A, use a compass with the width = 4 cm and the center is point A then you draw an arc such that it intersect line CD . After that, we will have a point (the intersection point) which is which is 240 cm from A and is on the line CD
- c) Plot a point which is 240 cm from A and is 96 cm from the line CD
96/60 = 1.6 cm
We will D draw a line parallel to CD at a distance of 1.6 cm, then we will use use a compass with the width = 4 cm and the center is point A then you draw an arc such that it intersect line CD.
Hope it will find you well.
You'll be solving:
-5t^2 + 20t + 15 = 3t + 3
5t^2 - 17t - 12 = 0
(t - 4)(5t + 3) = 0
t = 4 or t = -3/5, but let's assume t ≥ 0
