Answer: (5,3)
Step-by-step explanation:
the formula used for a reflection across the x-axis is (x,-y)
8 blocks because 2/10=1/5 so if they total 4/5 then 2/10+2/10+2/10+2/10=8/10=4/5
Answer:
68%
Step-by-step explanation:
25-8=17
17/25=0.68
68%
Hope this helped :)
Answer:
<h2> 10 in</h2>
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, circles and square.
we know that the pizza has a circular profile
and the place-mat has a square profile.
Step one:
let us solve for the radius of the pizza
Step two:
from inspection we know that the width of the place-mat is same as the diameter of the pizza
hence diameter of pizza
= 2r
=2*5
=10 in
When you factor this quadratic (or any polynomial, for that matter), what you get are the zeros of the function. When the object is on the ground, its height is 0. The zeros of a function are where the graph goes through the x-axis. Where the graph goes through the x-axis, the y value is 0. Using the quadratic formula to factor this gives you zeros of t = -1 and t = 7. The two things in math that will never EVER be negative are time and distance/length, so we know that object will hit the ground 7 seconds after it is thrown.
