(8/9)^2= 8/9 * 8/9
8*8=64
9*9=81
Final answer: 64/81
Answer:
Let x = cube root of 400
Using a calculator x = 7.368 to 3 decimal places
So: 7 < x < 8
Answer:
20
Step-by-step explanation:
The figure can be broken up into 4 congruent right triangles
with sides of 3 and 4.
Which makes a classic 3-4-5 right triangle
The 5 side is on the perimater
4 * 5 = 20
Sydney can read 0.8 pages a minute
Solution: you divide the time by the amount of pages read
To confirm 0.8 x 50 = 40
Answer:
-1.2
Step-by-step explanation:
Given that the designer also programs a bird with a path that can be modeled by a quadratic function.
The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).
If we treat this curve as line joining these two points then we can find the slope by the formula
Slope = change in y coordinate/change in x coordinate
Here the points given are
(0,20) and (10,8)
![Change in y coordinate = 8-20 = -12\\Change in x coordinate = 10-0 = 10\\Slope = -1.2](https://tex.z-dn.net/?f=Change%20in%20y%20coordinate%20%3D%208-20%20%3D%20-12%5C%5CChange%20in%20x%20coordinate%20%3D%2010-0%20%3D%2010%5C%5CSlope%20%3D%20-1.2)
Slope of the line that represents the turtle's path
=-1.2
