Answer:
55.8
Step-by-step explanation:
Answer:
3x = 50 - 10y
Step-by-step explanation:
Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,
So, total weight of 3 lb weights = 3x
And, the weight of 10 lb weights = 10y
Total weight of all his weights = 3x + 10y
According to the question,
Total weight = 50 lb,
⇒ 3x + 10y = 50
Or 3x = 50 - 10y
Which is the required equation.
Second option is correct.
Are you trying to make an algebraic equation?
x = # of trees
y = gal of water
It would be 30x = y
Answer:
Step-by-step explanation:
the Pythagorean theorem is
c is the hypotenuse which is the side opposite of the right angle
plug the numbers into the Pythagorean theorem

when squaring a square root, just take the number in the radical and get rid of the radical

subtract 26 from both sides


find the square root of 143
143 is prime so it can just be written as

Answer:
The correct option is;
Segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A
Step-by-step explanation:
All chords perpendicular to the radius of a circle are bisected by the radius of the circle
Given that DA can be extended to the circumference of circle A to form a radius of the circle A, and that DA is perpendicular to EF, therefore, DA bisects EF or EF is bisected into two equal parts by DA such that segment ED is congruent to segment FD
Therefore, the correct option is that segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A.
