Answer:
-0.75k - 2.0
Step-by-step explanation:
0.25k + 1.5 − k − 3.5
Combining like terms with rational coefficients
0.25k + 1.5 - k - 3.5
Collect like terms with rational coefficients
=0.25k - k + 1.5 - 3.5
= -0.75k - 2.0
Answer equals negative zero Point seven five k minus two point zero
Answer:
188.496
Step-by-step explanation:
A=2πrh+2πr^2=
A=2·π·3·7+2·π·3^2
A= 188.49556
Rounded up because 4th decimal is a 5.
A= 188.496
Answer:
True is the answer GL GL GL
Answer:
8.090169944 or rounded 8.1
Step-by-step explanation:
Use SOH CAH TOA
Look at x and where it is and what you have.
First thing is to get an angle to use, 36, then to set up your equation.
___(36)=___
Figure out what you have.
You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.
You set up your equation using COS, as you are using CAH.
Cos(36)=x/10
X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse
Switch it around to make it equal to x
10*Cos(36)=x
You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.
Round however is needed.
Answer:
648. if you were meaning 36 x 18
but if you meant 36/18 then it is 2
