Answer:
10 pounds.
Step-by-step explanation:
Let x pounds be the amount of mixed nuts we require.
Amount of peanuts in this mix = 0.70x pounds. Amount of peanuts in the 20% mix = 0.20*15 = 3 pounds.
So we have the equation:-
0.70 x + 3 = 0.40(x + 15)
0.70 x + 3 = 0.40(x + 15)
0.70x + 3 = 0.40x + 6
0.70x - 0.40x = 6 - 3
0.30x = 3
x = 10.

-9 tells the distance between her hand and the keys
The units (-3,-1) and (-0,-0) are the following units located at (-4,-2).
Answer:
18.
Step-by-step explanation:
1) formula of the perimeter given in the condition is:
p=2(VW+XV) or p=2(VY+XY).
Note, VW=XY and XV=VY;
2) if to substitute p=84, VW=2z+2 and XV=3z into the formula above, then
2(2z+2+3z)=84, ⇔ 5z+2=42; ⇒ z=8.
3) if z=8, then VW=2z+2=2*8+2=18.
<span>1,500 milliliters is equal to 1.5 liters. In the metric system, a liter is the basic unit of volume for liquids. Like the rest of the metric system, the naming system uses prefixes derived from Latin and Greek roots that tell the user what fraction or multiplier the unit uses. In this example, "milia" is "thousand" in Latin. Thus, a "milli-liter" is a thousandth of a liter. Learning these prefixes makes the use of the metric system much easier.</span>
