10 now have a good one at the max
Answer:
A choice
Step-by-step explanation:
sec is defined as 1/cos.
cos is again defined as adjacent to hypotenuse.
We know that adjacent is x and hypotenuse is r.
Therefore:- cos is x/r
Now sec is 1/cos = 1/(x/r)
1 ÷ x/r is 1•r/x
Thus:-
sec is r/x
We have 1.2 × 10^(-4) x 6.25 × 10^(-5 ) = 7,5 x 10^(-9) = 75 x 10^(-10) square kilometers.
Answer:
height equals 5 inches
Step-by-step explanation:
base = 6
area = 15
area = 1/2(6)h
15= 3h
5=h
Answer:
A
Step-by-step explanation:
Okay here's my reasoning:
they are telling us that 3 and 5 put together is 8. While this could be either A or D, this question has already told us that it equals 8. This equation is basically more better suited to 8=3+5 because this is show that 8 can be found by putting 3 and 5 together.
Hope this helps!
