6.3 r < -45.36

Here first we have to solve for r and for that we need to get rid of 6.3 .

To get rid of 6.3, we divide both sides by 6.3 that is

r < -7.2

So the solution is all the values which are less then -7.2

And for graph, we put a blank circle or a parenthesis that is () on -7.2 and extend a line to the left side since the inequality is less then .

What are the areas of each smaller rectangle and the large rectangle?

zhannawk [14.2K]

Answer:

Area of part 1: 3 * $5\sqrt{2}$ = $15\sqrt{2}$

Area of part 2: $3\sqrt{2} * 5\sqrt{2}$ $=30$

Area of entire rectangle: $30 + 15\sqrt{2}$

Step-by-step explanation:

The area of a rectangle can be found by using formula : length * width.

The area of part 1 can be simplified to this:

3 * $5\sqrt{2}$ = $15\sqrt{2}$

Area of part 2:

$3\sqrt{2} * 5\sqrt{2}$ $=30$

The area of the entire rectangle can simply be added from part 1 and part 2.

For area 2, remember multiplying the square root of 2 twice nullifies the square root. So it becomes 15 * 2, which is equal to 30.

KiRa [710]

Answer:

If he divide the trail mix among 8 hikers equally each will get 48/8 = 6 ounces.

Step-by-step explanation:

He makes a trail mix . He mixed 1 1/8 pounds of peanuts , 12 ounces of raisins, 11 ounces of walnuts and 7 ounces of pretzels. Notice the weight units are not equal to we have to convert the pounds to ounces so all the weight will be in ounces.

1 pound = 16 ounces

1 1/8 pounds = ? ounces

cross multiply

1 1/8 × 16

9/8 × 16 = 18 ounces

Therefore,

His trail mix are

18 ounces of peanuts

12 ounces of raisins

11 ounces of walnuts

7 ounces of pretzels

The total weight = 18 + 12 + 11 + 7 = 48 ounces

Weight of the trail mix = 48 ounces

If he divide the trail mix among 8 hikers equally each will get 48/8 = 6 ounces.
