Answer:
6. angle D and B
7 angle D and A
8 mA=140 and mB=40
9 mC=140 and mD=40 because they are congruent
Answer: 14.95
Step-by-step explanation: Set up the equation. On a piece of paper, write the dividend (number being divided) on the right, under the division symbol, and the divisor (number doing the division) to the left on the outside. ...
Divide the first digit. ...
Divide the first two digits. ...
Enter the first digit of the quotient.
Let
b---> the original amount of blue balls in the bag
p---> the original amount of pink balls in the bag
we know that
b=8+p
p=5
so
b=8+5----> b=13
step 1
Find the total of balls originally in the bag
total =13+5-----> 18
step 2
find <span>the probability that a person will pick a blue ball first
</span>Find P(b)
P (b)=13/18
step 3
Find the probability that a person will pick a pink ball second <span>without replacement
the total of balls now is (18-1)-------> 17
P(p)=5/17
step 4
Find </span><span>the probability that a person will pick a blue ball first and then a pink ball without replacement
</span>(13/18)*(5/17)-----> (13*5)/(18*17)------> 65/306-----> 0.21
the answer is
0.21
Answer:
b) 6/7
c) 14
Step-by-step explanation:
b) Scale Factor = Red/(Red+Blue) = 8/(8+6) = 8/14 = 6/7.
c) x = 8+6 = 14.
EXTRA TIP: If you aren't sure, think about wheter these triangles are isosceles(from the diagram). Hope this helps!
320 has the same value as 32 tens.
