Answer:
Angle y and Angle x are complementary angles
Step-by-step explanation:
we know that
If
sin(y°)=cos(x°)
then
Angle y and Angle x are complementary angles
so
∠y+∠x=90°
∠x=90°-∠y
sin(y°)=cos(90°-y°)
therefore
The sine of an angle is equal to the cosine of its complementary angle
Answer:
Honestly I don’t know I need help
Step-by-step explanation:
Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.
Answer:
The required equation is
4p = 2.24
And p = 0.56 [ where p is in $]
Step-by-step explanation:
Given that Selena buys 4 peaches that weight 1 pound in all.
Peaches are on sale for $2.24 per pound.
Since the total weight of peaches is 1 pound.
So the price of 4 peaches is $2.24.
Let p be the price of 1 peaches.
Then the price of 4 peaches is $(4×p)
= $4p
According to the problem,
4p = 2.24

⇒p=0.56 [ where p is in $]
The required equation is
4p = 2.24
And p = 0.56 [ where p is in $]
