Answer:
The answer will be:
b ≥ 10
Step-by-step explanation:
The bracelets cost $2 and the earrings cost $3.
She needs to make at least $60.
She will need to sell more than 10 bracelets.
b = bracelets
e = earrings
2b+3e ≥ 60
Answer:
A. It would become a different atom.
C. Its charge would increase by 1
Step-by-step explanation:
Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
So we need to find the sum of the first 5 terms.
You have told me that the first term is 10 meters, and that r = 0.5 per term.
With this knowledge, we can use the formula s_n=a₁((1-r^n)/(1-r)).
Plugging in the terms that we know...
s₅=10((1-0.5⁵)/(1-0.5))
s₅=10(0.96875/0.5)
s₅=10(1.9375)
s₅=19.375
With s₅, we can determine that the ball has traveled a total of 19.375 meters after 5 bounces.
Answer: Option A.
Step-by-step explanation:
You need to use this formula for calculate the surface area of the right cylinder:
Where "r" is the radius and "h" is the height.
You can identify in the figure that:
Knowing this, you can substitute these values into the formula , therefore you get that the surface area of this right cylinder is:
