Yo sup??

the angle is in 3rd quadrant.

we can say that

sin(90+150)

=sin(180+60)

=-sin(60)

=-3^(1/2)/2

Hence the correct answer is option A

Hope this helps

A machine in a factory builds 15 toys in 135 min. How many toys does the machine build in 216 min?
irina1246 [14]
The answer is 24. To get this answer I divided 135 by 15 to see how many minutes it takes to make each toy. My answer was nine, so I divided 216 by nine and got the answer, 24.

Im haveing problems with slope interception for an example
DanielleElmas [232]
Slope intercept form
y=mx+b
where the slope is m and b is the y intercept



the slope is needed
slope between (x₁,y₁) and (x₂,y₂) is (y₂-y₁)/(x₂-x₁)

so,
given (4,5) and (8,9)
the slope is (9-5)/(8-4)=4/4=1


y=1x+b
find b
input a point
(4,5)
x=4 and y=5
5=1(4)+b
5=4+b
minus 4 both sides
1=b
y=1x+1 is  slope intercept form

K I don't feel like doing this either so.

Answer: 68 minutes or 1 hour and 8 minutes spent in all putting up the fence

Step-by-step explanation:

(4/5) x 60 = 48 minutes

4/5 is the same as 0.8, which is what you get when you divide four by 5

So, 0.8 x 60 = 48 is also acceptable

Then,

(1/3) x 60 = 20 minutes

1/3 is the same as 0.333333333333, which is what you get when you divided 1 by 3

So, 0.33333(and so on) x 60 = 20

- Typically, you can round 0.3333333 down to something like 0.333 which should give you a similar answer

Then, as it asks you for how much time he spent in all, you add those two together

48 minutes + 20 minutes = 68 minutes  OR 1 hour and 8 minutes (There is sixty minutes in 1 hour, so subtract the 60 from 68 and then you have 8 minutes left, thus 1 hour and 60 minutes)

The speed of a car is x miles per hour.
stiks02 [169]

y = 0.5x , because car travels x miles in one hour (60 minutes), therefore it will travel half of x miles in half hour
