Answer:
$55
Step-by-step explanation:
1) since we are taking 50% of the price of lets find 50% of 110
so 0.50*110=55
50% of 110 is 55 hence we can subtract 55 from 110(since its getting marked down)
110-55=55
$55 is the new price
Hope this helps!
Answer:
Hey!
Step-by-step explanation:
x < 4 Is your answer.. Here is the graph :)
Your answer for the second one is x > 3
Graph is also down below :)
Hope this helps!
Since both α and β are in the first quadrant, we know each of cos(α), sin(α), cos(β), and sin(β) are positive. So when we invoke the Pythagorean identity,
sin²(x) + cos²(x) = 1
we always take the positive square root when solving for either sin(x) or cos(x).
Given that cos(α) = √11/7 and sin(β) = √11/4, we find
sin(α) = √(1 - cos²(α)) = √38/7
cos(β) = √(1 - sin²(β)) = √5/4
Now, recall the sum identity for cosine,
cos(x + y) = cos(x) cos(y) - sin(x) sin(y)
It follows that
cos(α + β) = √11/7 × √5/4 - √38/7 × √11/4 = (√55 - √418)/28
Answer:
-50 - 15y
Step-by-step explanation:
-5 ( 10 + 3y )
First distribute the -5 by multiplying it by 10 and 3y
(-5 x 10) + (-5 x 3y)
Than simplify
(-50) + (-15y)
Adding a negative is like subtracting a positive so you can turn (-50 + -15y) into (-50 - 15y)
Than you have your answer
-50 - 15y
