Answer:
26
Step-by-step explanation:
DE+EF=DF
Subsitue thise x values for DE, and DF
12+x=38
=26
Answer:
226.08 square inches
Step-by-step explanation:
Area of a circle is given by
Where r is the radius and r is the area.
For this case, since one half is painted yellow and another red, then the area for each paint will be given by
Substituting 12 inches for r then
Therefore, each paint occupies approximately 226.08 square inches
Answer: 12
Step-by-step explanation:
For this counting question, we need to figure out the possible choices for each selection.
For main protein, there are four options, so we can make four slots
_ _ _ _
For beans, there's three options, so we can make three slots
_ _ _
Doing some casework, we know that 4*3 = 12, which is the answer.
Answer:
Answer:
9.46 = y
Step-by-step explanation:
=================================================================
You have to use the cosine function equation.
cos(38) =
Multiply 12 on both sides.
12cos(38) = y
Solve.
9.46 = y
How to know which one to use:
Sin, Cos, Tan, Sec, Cosec, and Cot
Sin function is to do opposite number side length over the hypotenuse number side
Cos function is to do adjacent (side length that is next to angle) over the hypotenuse
Tan function is to do Opposite over Adjacent,
These are the inverse of each one
Sec is hypotenuse over opposite (inverse of Sin)
Cosec is hypotenuse over adjacent (Inverse of Cos)
Cot is Adjacent over Opposite (Inverse of Tan)
=================================================================
Step-by-step explanation:
When r = 5 and n = 2
Then
6r + 4n
= 6 * 5 + 4 * 2
= 30 + 8
= 38
