Answer:
x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65
Step-by-step explanation:
x= −b±√b2−4ac
/2a
x=
−(1)±√(1)2−4(−2)(8)
/2(−2)
x=
−1±√65
/−4
x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65
The water is 95% of the total weight of watermelon. Multiply 95% by the total weight to get the weight of the water.
water = 95% × 20
water = 0.95 × 20
water = 19
The weight of the water is 19 lbs
<span>In order to find the breakeven number of game rentals, we need to find the point at which the costs are equal. To do this, we set two expressions as a function of the number of games, equate them, and solve.
For Fun Guys, cost C = 20 + 6.5g, where g is the number of games
For Game Bank, C = 50 + 3.5g
Equating -> 20 + 6.5g = 50 + 3.5g -> 3g = 30 -> g = 10
At 10 games, the cost will be the same for both stores, and that cost is 50 + 3.5* 10 = 20 + 6.5*10 = $85.</span>
22.5 cm because 6 divided by 1.2 = 5 so 5 x 4.5 = 22.5
Answer:
Step-by-step explanation:
Let's start with distributing: 
Simplify i with i in the second term, and rearrange.
. Since i in the denominator looks ugly, let's multiply top and bottom by i. 
. The middle passage is based on the fact that, by definition,
