14(y) = 70
y = 70/14
y = 5
hope this helps
It wouldn’t be 3.6ft because that’s how long the adult’s shadow is. It also couldn’t be 4ft because, it wouldn’t make sense for the child to be taller. I think 2.6ft is the best choice .
Answer:
24 picture frames
Step-by-step explanation:
Since a student takes 1/6 hour to paint a picture frame, so in an hour, the student will paint a total of 6 picture frames. So to find the number of picture frames in 4 hours, you just need to multiply 4*6 to get 24 picture frames.
The answer would be 910 because numbers 1-4 round down to the nearest tenth and numbers 5-9 round up to the nearest tenth. This number ends in 7, so we would round up to the nearest tenth. This would make the correct answer 910
Answer:
(x - 2)² + (y - 9)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (2, 9) and (x₂, y₂ ) = (2, 6)
r = ![\sqrt{(2-2)^2+(6-9)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%282-2%29%5E2%2B%286-9%29%5E2%7D)
= ![\sqrt{0^2+(-3)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B0%5E2%2B%28-3%29%5E2%7D)
=
=
= 3
Centre = (h, k) = (2, 9) and r = 3, thus equation of circle is
(x - 2)² + (y - 9)² = 9
