Hi
Left to do 40% of the shopping
12 items ⇒ 60% of the items
x items ⇒ 40% of the items
60x = 12(40)
60x = 480
x = 480/60
x = 48/6
x = 8 items
Answer:
Left 8 items of the list (40% of the shopping)
Items: 12+8 = 20 items on her list
Answer:
1/4
Step-by-step explanation:
Ariana cannot ship all the bags in one box.
Ariana will be sending 8 bags which will weigh a total of:
= 22 ounces x 8
= 176 ounces
You need to convert this to pounds to see if it will fit in the box:
<em>1 pound = 16 ounces </em>
176 ounces in pounds is therefore:
= 176 / 16
= 11 pounds
The box can only take 10 pounds and 5 ounces which is less than the 11 pounds the bags weigh.
Ariana cannot ship all the bags in one box.

The number of positive roots is the number of changes of signs there are, then decrease by 2 each time and stop when you get to 1 or 0
negative roots, sub every x with -x and reevaluate, count change of signs
decrease by 2 each time and stop when you get to 1 or 0
y=+2x⁵-x⁴-2x³+4x²+x-2
+,-,-,+,+,-
1 2 3
3 or 1 positive roots
replace x with -x ( baically flip all signs of odd powerd numbers)
y=-2x⁵-x⁴+2x³+4x²-x-2
-,-,+,+,-,-
