Answer:
The weight of the zinc in the metal bar was 50% of the weight of the metal bar .
Step-by-step explanation:
Weight of the metal bar ,M= 36 g
Weight of the zinc in the metal bar , m= 18 g
Percentage of zinc in the metal bar :
The weight of the zinc in the metal bar was 50% of the weight of the metal bar .
theres y=1/2x+7. the line will be parallel as long as you do not change the x value!
Answer:
True
Step-by-step explanation:
The integral
in the integral we have a product of a monomial: 
and an exponential function: 
In general case, when we have a combination of these two things you can use the integration by parts, where will be 
and will be 
.
The statement is true
2. The area for a circle is as follows:
A = π
The radius of the circle is 4 in, so we plug that into the equation.
A = π (4
)
4
= (4 in.)(4 in.) = 16
A = 16π
This is the area for the whole pizza, so divide that by 2 to get the area of the pepperoni
a) 8π
For the bacon, we can just divide the value we already have by 2, since it is half the area of the pepperoni
b) 4π
3. This question is asking for the circumference, whose equation is as follows:
C = 2 π r
We can use the area formula, A = π
to find the radius of this circle
36π = π
Divide both sides by π:
36 =
Square root both sides:
r = 6 in.
Plug in this value to the circumference formula, C = 2 π r
C = (2)(π)(6 in.)
Your final answer is:
C = 12π in.
