Answer:

Expanded notation: 480000

Step-by-step explanation:

10 to the 4th power is 10000

so 48 times 10000 equals 480000.

Earth is approximately 9.3 × 10^7 miles from the sun and Saturn is approximately 8.87 × 10^8 miles from the sun. Approximately h

denis23 [38]

Answer:

7.94 x 10⁸miles

Step-by-step explanation:

Given parameters:

Distance of earth from sun = 9.3 x 10⁷miles

Distance of earth from Saturn = 8.87 x 10⁸miles

Unknown:

How much further from the sun is Saturn than Earth = ?

Solution:

To find the solution to this problem, let us find the difference between their distances:

( 8.87 x 10⁸ miles - 9.3 x 10⁷ miles )

= 88.7 x 10⁷ miles - 9.3 x 10⁷ miles

= (88.7 - 9.3) x 10⁷miles

= 79.4 x 10⁷miles

= 7.94 x 10⁸miles

Mr. Ailey gave his class 45 minutes to read. Davida reads 27 3/4 pages in that time. At what rate, in pages per hour, did Davida

Rudik [331]

Answer:

37 pages per hour

Step-by-step explanation:

Given that :

Time Given to read = 45 minutes ; 45 / 60 = 0.75

Number of pages readable ad by Davida within the given time frame = 27 3/4 pages

David's reading rate in pages per hour :

Number of pages read / time taken (hrs)

[27 3/4] ÷ (45/60)

[111 / 4] ÷ (45/60)

(111 / 4 ) * (60/45)

(111 * 60) / (4 * 45)

6660 / 180

= 37 pages per hour

Find the perimeter of the triangle to the nearest whole unit.<br> 18.<br> 16.<br> 14.<br> 12.

devlian [24]

Answer:

Step-by-step explanation:

Perimeter of the ∆ = sum of the length of the 3 sides.

The length of the 3 sides can be calculated by using the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , to find the distance between the vertices of the ∆.

The coordinates of the 3 vertices are:

(-1, 3), (2, 2), (-2, -2)

Distance between (-1, 3) and (2, 2):

Let,

$(-1, 3) = (x_1, y_1)$

$(2, 2) = (x_2, y_2)$

$d = \sqrt{(2 -(-1))^2 + (2 - 3)^2}$

$d = \sqrt{(3)^2 + (-1)^2}$

$d = \sqrt{9 + 1} = \sqrt{10} = 3.2 units$

Distance between (2, 2) and (-2, -2)

Let,

$(2, 2) = (x_1, y_1)$

$(-2, -2) = (x_2, y_2)$

$d = \sqrt{(-2 - 2)^2 + (-2 - 2)^2}$

$d = \sqrt{(-4)^2 + (-4)^2}$

$d = \sqrt{16 + 16} = \sqrt{32} = 5.7 units$

Distance between (-2, -2) and (-1, 3)

Let,

$(-2, -2) = (x_1, y_1)$

$(-1, 3) = (x_2, y_2)$

$d = \sqrt{(-1 -(-2))^2 + (3 -(-2))^2}$

$d = \sqrt{(1)^2 + (5)^2}$

$d = \sqrt{1 + 25} = \sqrt{26} = 5.1 units$

Perimeter of triangle = 3.2 + 5.7 + 5.1 = 14.0 units
