Answer:
x= ± 
+2
Step-by-step explanation:
Use the formula ( b/2) ^2 in order to create a new term. Solve for x by using this term to complete the square.
x= ± +2
It would be = because they shipped the same amount in each year
Answer:
Step-by-step explanation:
Final concentration % = [grams of salt / mililiters of solution] * 100
grams of salt = grams of salt from solution 1 + grams of salt from solution 2
grams of salt from solution 1 = mililiters * %/100 = 80 mililiters * 0.25 g/mililiters = 20 g
grams of salt from solution 2 = mililiters *%/100 = x*0.10 g/mililiters = 0.1x
mililiters of final solution = mililiters from solution 1 + mililiters from solution 2
mililiters of final solution = 80 mililiters + x mililiters
=> Final concentration, % = [0,10x + 20 g] / [x + 80 mililiters] * 100
Answer:
Area of the 2 circles
= 2 pi r square root
= 2 x 3,14 x 21 x 21
=6,28 x 441
=2769.48inches square
Area of the rectangle
= L x h
= where is the other number bc then u cant solve it
Step-by-step explanation:
1.
k = 1
J = 7(1) + 5
J = 12
k = 1 + 2 = 3
J = 7(3) + 5
J = 26
26 - 12 = 14
J increases by 14.
2.
1/6 = 0.16 false (1/6 = 1.67)
0.08 = 4/5 false (0.08 = 8/100 = 2/25)
0.25 = 1/4 true (0.25 = 25/100 = 1/4)
<span>1/3 = 0.3 true (if rounded)</span>
<span>
3.
12 candles in 3 hours
12 </span>÷ 3 = 4
4 candles in 1 hour
4 × 8 = 32
32 candles in 8 hours
4.
$3.45 for 64 ounces
3.45 ÷ 64 = 0.05
$0.05 or 5 cents per ounce
5.
75 is what percent of 250?
75 ÷ 250 = 0.3
0.3 × 100 = 30
30%
