Answer:
Step-by-step explanation:
Tom: 90 cookies total 60% were sold
Tom: 90 * 60/100 = 54 cookies
Scott: 150 cookies and 2/3 were sold
Scott: 150 * 2/3 = 300/3 = 100
Dawn: sold 46 cookies
Total Sold = 46 + 100 + 54
Total Sold = 200
Answer
Dawn: % = (46 / 200) * 100 = 23%
If DF is a tangent segment and it is tangent to the radius, then we have got a right triangle. And this right triangle is a triangle RDF. So that, the correct answer is C) RDF is a right triangle.
If the store is 2 6/8 miles from his house, he still has 1 1/2 miles to walk.
The total there and back would be twice the 2 6/8 or 5 1/2 miles.
That is if I am reading it correctly. The periods are still confusing.
Answer:
{x,y} = {2,3}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = -2y + 8
// Plug this in for variable x in equation [1]
[1] 4•(-2y+8) - y = 5
[1] - 9y = -27
// Solve equation [1] for the variable y
[1] 9y = 27
[1] y = 3
// By now we know this much :
x = -2y+8
y = 3
// Use the y value to solve for x
x = -2(3)+8 = 2
