The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of planet Venus from the Sun
slega [8]

Answer:

5.2

Step-by-step explanation:

distance(Mercury, Sun) = 5.8 x 10^7

distance(Venus, Sun) = 1.1 x 10^8

distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7

The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.

simply subtract 5.8 from 11.0.

This gives us a result of 5.2 x 10^7.

Answer:

66.91 km^2

Step-by-step explanation:

This answer will be long:

Interior angles of hexagon sum to  (4)(180) = 720   each is 120 degrees

 each side is 24/6 = 4 km    

    area of hexagon =  12  *  1/2 2 * (2 tan60) =<u> 41.5692 km ^2 </u>

L triangle   5 = hypot   leg1 = 4    leg2 = 3    area = 1/2 * 3 * 4 =<u> 6 km^2</u>

TOP triangle is 4 = hypot    leg1 = 3.464      leg2 = 2  

                                       area = 1/2 * 3.464 * 2 = <u>3.464 km^2</u>

R triangle  two legs = 4    area   = 1/2 * 4 x 4 =<u> 8 km^2 </u>

BOTTOM triangle   two sides = 4       use sin rule   sin40/4  = sin 100/x

                third side = 4/sin 40  * sin 100 = 6.1284 km

             semi perimter = ( 4 + 4 + 6.1284) / 2 = 7.0641 km

                Use Herron's rule for area =

                  sqrt ( 7.0641 (7.0641-4)(7.0641-4)(7.0641-6.1284) ) =<u> 7.878 km^2 </u>

<u> add all of the areas to get  66.91 km^2  (IF I made no math errors!) </u>

brilliants [131]

Answer:

(0,0) (3,2) and (-2,-2) (4,2)

Step-by-step explanation:

To find the slope, you do \frac{y_{1}-y_{2} }{x_{1}-x_{2}}, which would work for both.

2-0/3-0=2/3

2-(-2)/4-(-2)=2+2/4+6=2/3

Here is Triangle A. Lin created a scaled copy of Triangle A with an area of 72 square units. C. What is the length of bottom sid
satela [25.4K]

Answer:

The length of bottom side of the scaled copy is 12 u

Step-by-step explanation:

To solve this problem we have to know that to calculate the area of ​​a triangle we use the following formula

a = area

b = base

h = height

a = b * h

In the triangle A the base and the height are equal to 3

b = h

Now that we know that b & h we can calculate the base of the scaled copy

72 u² = b * b

72 u² = (b)²

√(72 u²) = b

12 u = b

The length of bottom side of the scaled copy is 12 u
