<span>A polygon is classified by how many ____angles_______ it has.</span>
1=2x^2-7
2x^2=8
x^2=4
so x=2 or x=-2
Answer:
a) 80 ibs
b) 40 ibs
Step-by-step explanation:
Let X be the pound of the high quality bean at $6.50
(120-x) will be the pound of the cheaper bean at $2.50
6.5x + 2.5(120 - x) = 5.17(120)
6.5x + 300 - 2.5x = 620.4
Collect like terms
6.5x - 2.5x = 620.4 - 300
4x = 320.4
x = 320.4/4
x= 80.1
x = 80 ibs(to the nearest pounds)
For the cheaper bean we have 120 -x
= 120 - 80
= 40 ibs
Sarah would blend 80 ibs of quality bean and 40 ibs of cheaper bean
Answer: 2.2 miles.
Step-by-step explanation:
I guess that we want to find the distance between Lori's and Andrea's houses.
First, we have the locations:
L = (-3, 7)
A = (-3. -4)
To find the distance (in units) between two coordinate points (a1, a2) and (b1 b2) we can use the formula:
Distance = I (a1, a2) - (b1, b2)I = √( (a1 - b1)^2 + (a2 - b2)^2)
Then in this case we have that:
Distance = √( ( -3 -(-3))^2 + (7 - (-4))^2) = √( 0 + 11^2) = 11
The distance between their houses is 11 units.
And we know that each unit represents 0.2 miles, then 11 units represent 11 times that amount, the distance in miles will be:
D = 11*0.2 miles = 2.2 miles.
14 ounces is about .39 kilograms. So 14 ounces is greater than .4 kilograms
