It should be 10, The scale goes off of what the numbers count by so like 10,20,30,40,50,60 if I’m not mistaken
Answer:
The answer is A because when you take both X and Y they are both negative so the only way to keep the answer negative would be to add them.
If you subtract one from the other it adds the opposite
If you multiply them the negatives cancel each other and the answer becomes positive
If you divide them the negatives cancel out and so again the answer would be positive
Step-by-step explanation:
When you add an negative number to another negative number your number stays negative
Answer:
A)
P=2x+2\pi rP=2x+2πr
B)
x=\frac{1}{2}(P-2\pi r)x=
2
1
(P−2πr)
C)
x\approx173\text{ feet}x≈173 feet
Step-by-step explanation:
So, the track is composed of a rectangle and two semicircles.
The side length of the rectangle is x, and the radius of the semicircles is r.
Part A)
The perimeter is simply the length around the figure.
We can see that the perimeter will be equivalent to two times x plus two times the circumference of the semi-circles.
Answer: in the 3 pairs we can find a rational number.
Step-by-step explanation:
A rational number can be any number written as a quotient of two integers.
The rational numbers have a finite number of decimals after the point (or periodic)
a) (-10, -9)
between those two numbers we have, for example, -9.5
and we can write this as:
-9.5 = 95/100
b) (5.91, 5.92)
between these numbers, we have the number 5.915
and we can write it as: 5.915 = 5915/1000
c) (2/3, 4/5)
between 2/3 and 4/5 we have for example the number 3/4.
because 2/3 = 0.66....
4/5 = 0.80
a number between those two is 0.75 = 3/4.
