Answer:
A. -3(5x - 13)
Step-by-step explanation:
When you open the bracket
You have -3 x 5x -3(-13)
Negative negative gives you positive
Then it becomes
-15x + 39
Answer: The width is 10.2 inches, the perimeter is 71.4, the area is 260.1.
Step-by-step explanation: So first i divided 25.5/5 which equals 5.1. The ratio is 2:5 so I know that i have to multiply 5.1x2 which is 10.2, thats how you get the width. The perimeter I just did 25.5+25.5+10.2+10.2 =71.4. For the area I just multiplied 25.5x10.2=260.1.
Answer:
Ganymede: A(sg) = 33.798.589 mil²
Earth´s moon: A(m) = 14.657.448 mil²
Ratio of surface areas : 2,31
Ratio of radio : 1,519
Step-by-step explanation:
We assume, ganymede and the moon both are spheres, according to tha the surface area of a sphere is:
A(s) = 4* π * r² r is radius in each case then we can calculte the surface area for ganymede A(sg) and moon A(m)
A(sg) = 4*3,1416 * (1640)²
A(sg) = 33.798.589 mil²
A(m) = 4*π* (1080)²
A(m) = 4 * 3,1416 * 1166400
A(m) = 14.657.448 mil²
Ratio of surface areas : 33798589/14657448
Ratio of surface areas : 2,31
Ratio of radio : 1640/1080
Ratio of radio : 1,519
