Answer:
The answer to your question is SA = 150.72 in²
Step-by-step explanation:
Data
Surface area = ?
height = 5 in
radius = 3 in
pi = 3.14
Formula
SA = 2πr² + 2πrh
Process
1.- Calculate the area of the bases
-Substitution
Area = 2(3.14)(3)²
-Simplification
Area = 2(3.14)(9)
-Result
Area = 56.52 in²
2.- Calculate the lateral area
-Substitution
Area 2 = 2(3.14)(3)(5)
-Result
Area 2 = 94.2 in²
3.- Calculate the total area
SA = 56.52 + 94.2
SA = 150.72 in²
Let the numbers be x and y. Then xy = -30 and x+y = -3.
Solve xy = -30 for y: y = -30/x
subst. -30/x for y in x+y= -3: x - 30/x = -3
Multiply all 3 terms by x: x^2 - 30 = -3x, so x^2 + 3x - 10 = 0
Solve this quadratic equation for x. x: {-5, 2}
If x = -5, then x+y = -3 becomes -5 + y = -3, and y = 2.
You should check to determine whether x=2 is also correct. If it is, what is the corresponding y value?

No I don't think so because a right triangle is equal to 90 degrees but when this all adds up it equals to 126 degrees
Answer: C
Step-by-step explanation:
The answer is C
Step-by-step explanation:
C The opposite of 9 is the same distance from 0 on a number line as the absolute value of 9.
Absolute value is the distance from zero on a number line of and number positive or negative.
