Answer:
140°
Step-by-step explanation:
edge just did the assignment
The <u>percentage</u> of a given <em>number</em> in another implies the fraction of the given <em>numbe</em>r to that other number <em>with respect </em>to 100%. Thus the required <u>expression</u> is: x n
When a given number is written in<em> percentage</em>, it implies that the<em> fraction</em> of the number to the<u> total </u>number in relation to 100%. For example, to determine the <em>percentage</em> of a number r in s, -we have:
x 100%
Therefore in the given question, the required <em>expression</em> is;
m% =
So that;
m% of n can be <em>expressed</em> as;
x n

Answer:
it would be 23%
Step-by-step explanation:
Answer:
a = 2
Step-by-step explanation:
given x = - 1 is a zero then f(- 1) = 0 , that is
a(- 1)³ - (- 1)² - 1 + 4 = 0
- a - 1 - 1 + 4 = 0
- a + 2 = 0 ( subtract 2 from both sides )
- a = - 2 ( multiply both sides by - 1 )
a = 2
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
