Answer:
1500
Step-by-step explanation:
525 is 35% of x, and we want to find x! (or, 100% of x)
So.
We set up an equation:
525 = 0.35x
How do we get to:
smth = 1.00x?
We divide both sides of the equation by 35, so it looks like this:
15 = 0.01x
And then we multiply both sides of the equation by 100, so it looks like this!
1500 = x
which means that Marla consumed 1500 calories that day.
Hope that helps!
Answer:
The second option
Step-by-step explanation:
The second option is correct because the base of the triangle, which is 3 cm, plus the base of the rectangle, which is 5 cm, is equal to the base of the trapezoid, which is 8 cm.
Hope this helps! :)
A. 4 is in the domain since the domain is 0≤x. There can't be negative books so that's why x must be greater than or equal to 0.
b. 60 is in the range since the range is 0≤y. There can't be negative books in this situation too.
(Correct me if I’m wrong in comments)
Answer: 80
Reasoning: A polyhedron can have 30 edges. If this polyhedron has 120 it has 4 times the “other” one. If it has 30 edges it will have 20 vertices, meaning 20*4=80 vertices
