Answer: 918km^2

Step-by-step explanation:

$area(a): 1700km^2\\percentage(p): 5.75 = \frac{5.75}{100}=0.0575\\years(y): 8$

Let x be the new dimension of the area;

$x=a-(a*p*y)$

$x=(1700km^2)-(1700km^2*0.0575*8)\\x=1700km^2-782km^2\\x=918km^2$

Answer:

The answer is 0.71 per ounce.

Step-by-step explanation:

You can use proportions to solve this.

$\frac{89.95 dollars}{64lb} = \frac{1 dollar}{x} \\64 * 1 = 64\\89.95 * x = 89.95x\\\\\frac{64}{89.95} = \frac{89.95x}{89.95}\\\\0.7115063924 = x\\Which when rounded to the nearest hundredths is:\\0.71$

Solve the inequality for u. 22≤-4u-2 Simplify your answer as much as possible.

larisa [96]

Answer:

u ≤ -6

Step-by-step explanation:

Given :

22 ≤ -4u - 2

Add 2 on both sides :

22 + 2 ≤ -4u - 2 + 2
-4u ≥ 24

Divide both sides by -4 (remember the sign changes direction when divided by a negative number) :

-4u/-4 ≥ 24/-4
u ≤ -6
