Answer:
Step-by-step explanation:
x + 5/y^2
x = 2/3
y = 1/3
2/3 + 5 / (1/3)^2 Expand (1/3)^2
2/3 + 5 / (1/9) Put a 1 underneath the 5
2/3 + 5/1 / (1/9) Invert and multiply the second expression
2/3 + 5/1 * 9 Simplify 5/1
2/3 + 5* 9 Combine
45 2/3
I'm not getting any of these. It's possible I'm misreading the question, but what you've given is the result I got. All I can suggest is that you ask your teacher how this is done.
Answer:
(B) 
Step-by-step explanation:
Given: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.
To find: The Surface are of Pyramid.
Solution: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.
Now, surface area of the Pyramid is given as:
where p is the perimeter and l is the slant height.
Now, area of base is given as:
And, the surface area is given as:
Hence, option B is correct.
Answer:
Hello its ok Love!
I believe x = 2 hope this helps good luck!
For this case, what we are going to do is first define variables.
x: current number of Americans.
y: number of Americans after the next 15 years.
We now write the expression to model the problem, assuming:
"the rate of increase continues in the same way for the next 15-year period".
We have then:
y = 1.76 * x
y = 1.76 * (3.09)
y = 5.44 million Americans
Answer:
the number of Americans on probation in 2010 might be:
y = 5.44 million Americans
Answer:
Step-by-step explanation:
Substitute m=(2x+1) and n=(6) in m+n=(9).
We are finding the value of the x variable.
Add the numbers on the left side of the equation.
Subtract 7 from both sides.
Divide both sides by 2.
The value of the x variable is 1.
