B
Step-by-step explanation:
Given
- 2.5(4x - 8) + 1.2(5x - 1)
Distribute both parenthesis
= - 10x + 20 + 6x - 1.2 → B
Answer: 342.32
Step-by-step explanation: sin(25) = h/a
Sin(25)= h/27
27*sin(25) = h
b*h = area
You have to use formula of combination
there are 13 heart in deck and 52 number of card in deck
now,
to find the probability that we choose two heart from deck , we use below formula

=5.88% so D is the answer
it's similar to usual probability method but using combination formula
Answer:
-2
Step-by-step explanation:
-324 ÷ -6 ÷ 3 ÷ -9 = 162
-324 ÷ 162 = -2
a parallel line has the same gradient, so the gradient would be 3 1/3
a perpendicular line has the negative inverse gradient of the original (eg. if the original gradient is 4/3 then the perpendicular gradient would be -3/4 (all you have to do is change the +/- sign and flip the fraction), so in your case the gradient of the perpendicular line would be -3/10 (since 3 1/3 = 10/3)
