Step-by-step explanation:
√a = 1√a so we can solve them easily:
b) 3√7 -√7= 3√7 - 1√7 =( 3-1)√7= 2√7
d) 5√6 - 2√6+√6= (5-2+1)√6 = 4√6
g) √2+2√2= 3√2
j) √5+5√5 - 3√5 = 3√5
k) 2√3 + √3 - 5√3= -2√3
I) 5√11 + 7√11 - √11 = 11√11
Events
• A: an even number is rolled in the first time
,
• B: a number greater than 3 is rolled the second time
The probability of rolling an even number is:
The probability of rolling a number greater than 3 is:
Events A and B are independent, then the probability of one happening after the other is:
Answer:
78
Step-by-step explanation:
13 jars/pizza
6 pizzas
13x6=78
Distribute
y+10+c=z
minus y from both sides
10+c=z-y
minus 10 both sides
c=z-y-10
For a dilation centered around the origin
Dk (x,y) = (kx, ky)
So let's say you have a rectangle PQRS where
P = (0,0)
Q = (4,0)
R = (4,4)
S = (0,4)
To get the dilation of this PQRS to P'Q'R'S' with scale factor 1/4 you multiply every coordinate by 1/4.
P' = (0.0)
Q' = (1,0)
R' = (1,1)
S' = (0,1)
The new cordinates for point q(1,0)
