Lateral area = 2 pi r l (r = radius and l = length)
so lateral area of r first light = 2 * pi * 1*16
and for second its 2 * pi * 1/3 * 23
Answer:
x=12
Step-by-step explanation:
Hello There!
So first things first, the angle labeled 4x+17 and the blank interior angle are vertical angles meaning that they are congruent
So now we can solve for x
Remember all of the angles in a triangle add up to equal 180 so
180 = x + 23 + 80 + 4x + 17
step 1 combine like terms
4x+x=5x
23+17+80=120
now we have
180=120+5x
step 2 subtract 120 from each side
180-120=60
now we have
60=5x
step 3 divide each side by 5
60/5=12
we're left with x=12
Answer:
Step-by-step explanation:
-10x+7(-6)=18
-10x-42=18
+42 +42
___________
-10x/-10=60/-10
x= -6
Answer:4
Step-by-step explanation:The GCF of 12 and 28 is 4. To calculate the GCF (Greatest Common Factor) of 12 and 28, we need to factor each number (factors of 12 = 1, 2, 3, 4, 6, 12; factors of 28 = 1, 2, 4, 7, 14, 28) and choose the greatest factor that exactly divides both 12 and 28
Answer:
The second one, the second to last one, and the last one.
Step-by-step explanation:
The second one is negative because if you add a negative number with a positive number it becomes negative.
The second to last one is zero because if you add a negative and a positive number that is the same number then it becomes zero.
And the last one, they are both simply positive.
Hope this helps <3
