<span>y-axis, a coordinate pair is (x,y) so when x = 0 the point must be on the y-axis.</span>
Answer: D) This triangle is a right triangle: 60^2+144^2 - 156^2 = 0
This is the same as saying 60^2 + 144^2 = 156^2
You would use the pythagorean theorem. In this case, a = 60, b = 144 and c = 156. The longest side is always the value of c. The order for the values of 'a' and 'b' do not matter. Convention usually has 'a' being the smaller of the two.
Answer:
Option D. 5890.5 feet²
Step-by-step explanation:
An individual head of a sprinkler system covers a circular are of grass with a radius of 25 feet.
Yard has three sprinkler heads that each cover circular area with no overlap.
We have to calculate the approximate area watered by these 3 sprinkler heads.
Area covered by one sprinkler = π×r² = π×(25)² = 625π feet²
Therefore area covered by three sprinkler heads = 3 × 625π = 5892.85 feet²
which matches the approximate value of Option D. 5890.5 feet²
Answer:
Point B = (-8 , -2) ⇒ the second answer
Step-by-step explanation:
∵ The figure ABCD is reflected across the x-axis
∴ The sign of y-coordinates of each point will change
Ex: If the point (x , y) reflected across the x-axis
its image will be (x , -y)
∵ B' = (-8 , 2)
∴ B = (-8 , -2) ⇒ the second answer
Answer:
and 20.5x
and 6.2y
Step-by-step explanation:
-3-x/5+6.2y+20.5x-3/8y
We are given an expression with 5 terms
The terms that has same variables with same exponent are like terms. WE combine only like terms. Constants are also like terms.
In the given expression , the fractions and 20.5x have same 'x' . so they are like terms. we can combine these terms.
the fractions and 6.2y have same 'y' . so they are like terms. we can combine these terms.
