Answer:
Weight of EACH square = 0.2 pounds
18% oat = 0.36 pounds
Step-by-step explanation:
Given that:
Weight of bag = 2 lb
Percentage of oat in mix = 18%
% of the mix is oats. (a) Use the 10 by 10 grid to represent 2 lb of trail mix. Determine how much weight each square represents and label all the squares. Then, shade in 18% of the grid. (b) What is the weight of the oats in the trail mix? Show your work and label your answer. Answer:
If trail mix is represented by 10 by 10 square grid ;
Each square represents : 2 pounds / 10 = 0.2 pounds
18% of the total weight
0.18 * 2 = 0.36 pounds
Answer:
Option 2: y = ±sqrt()
Step-by-step explanation:
y = 7x^2 - 10
To find the inverse of a function, you must swap the y and x.
x = 7y^2 - 10
Now I will just simplify to have y by itself on the left hand side.
x + 10 = 7y^2
=y^2
sqrt()=±y
y = ±sqrt()
Given:
A circle with diameter 9 cm.
To find:
The area of the circle.
Solution:
The area of a circle is:
...(i)
Where r is the radius.
We know that, the diameter of a circle is twice than its radius.
The diameter of the given circle is 9 cm.
Substituting in (i), we get
Therefore, the area of the given circle is 63.6.
