Answer:
30 degrees
Step-by-step explanation:
Since we know that all triangles equal 180 degrees, we can add the 2 given angles and subtract that from 180 to find the remaining angle.
90+60=150
180-150=30 degrees
Answer:
y = 3x+2
Step-by-step explanation:
First find the slope using the slope formula
m= (y2-y1)/(x2-x1)
= ( -1 - -4)/(-1 - -2)
= (-1 +4)/ (-1 +2)
= 3/1
= 3
The slope intercept formula is
y = mx+b where m is the slope and b is the y intercept
y = 3x+b
Using the point (-1,-1) and substituting into the equation
-1 = 3(-1)+b
-1 = -3+b
-1+3 = b
2 = b
y = 3x+2
Answer:
r = 7
Step-by-step explanation:
Given
r + 15 = 4r - 6 ( subtract 4r from both sides )
- 3r + 15 = - 6 ( subtract 15 from both sides )
- 3r = - 21 ( divide both sides by - 3 )
r = 7
Okay. Since we know that the customer before them bought one of each type of bulb, we can subtract one bulb from each type so now, here is what the store has:
5 amaryllis
6 daffodils
3 lilies
2 tulips
Next, let’s find the probability of the customer picking an amaryllis.
We know there are 5 amaryllis, so we can put that as the numerator.
Next, we have to add up all the flowers to get the denominator.
5+6+3+2
I got 16.
So now we have 5/16
So, that is our answer! 5/16, or as a decimal 0.3125, or as a percentage 31.25%.
