Answer:

<h3>D. 5 x 10⁶ ÷ 6.6 x 10⁴</h3>

Step-by-step explanation:

If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;

6.6 x 10^4 mi² = $5 X 10^6

1mi² = $x

Cross multiply;

$5 X 10^6 * 1 = 6.6 x 10^4 * x

6.6 x 10⁴ x = 5 X 10⁶

Divide both sides by 6.6 x 10⁴  to get x;

6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴

x = 5 x 10⁶ ÷ 6.6 x 10⁴

x = 0.76*10⁶⁻⁴

<em>x = $0.76*10²</em>

<em />

Hence the key strokes on a calculator will give the cost the  United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴

the cost to rent a hall for school functions is 60$ per hour. write an expression for the cost of renting the hall for h hours.
Firlakuza [10]
The expression for the amount of time rented would be:
C=60(h), I choose this expression because C would stand for cost, 60 for the amount per hour, and h for the piece of expression being given. Now when you need to find the amount per hour, the brackets means to times; so you'd plug in the hour needed to be found in h, and times 60 by the hour.

Your table should look like this :
COST PER HOUR            |            HOURS            |            COST
$60                                    |                 2                  |         $60 x 2 = $120
$60                                    |                 6                  |         $60 x 6 = $360
$60                                    |                 8                  |         $60 x 8 = $480
$60                                    |                10                 |         $60 x 10 = $600

Lawrence sells 40% of the apples on his cart, and are left with 420 apples. How many apples had Lawrence started with?
lutik1710 [3]

Answer:

700 apples

Step-by-step explanation:

Let

x = Total number of apples in the cart

Percentage of apples sold = 40%

Number of apples sold = Percentage of apples sold * Total number of apples in the cart

= 40% * x

= 0.4 * x

= 0.4x

Number of apples left in the cart = 420

Total number of apples in the cart = Number of apples sold + Number of apples left in the cart

x = 0.4x + 420

x - 0.4x = 420

0.6x = 420

x = 420/0.6

x = 700

x = Total number of apples in the cart = 700

Lawrence started with 700 apples

I need help with this
Nat2105 [25]

Answer:

angle B is 38°

Step-by-step explanation:

all angles in a triangle has to equal 180°.

So first find the measurement of angle BAD. This is done by subtracting angle of CAD=46° from the total angle CAB=78° to get 32° for angle BAD. So if angle ADB is 110° and angle BAD is 32° which equals (110+32=) 142.

Then take 180 - 142 = 38°
