Answer:

−5c5−15a−25b+10

Step-by-step explanation:

13+2−5−15a−25b−5c5

=13+2+−5+−15a+−25b+−5c5

Combine Like Terms:

=13+2+−5+−15a+−25b+−5c5

=(−5c5)+(−15a)+(−25b)+(13+2+−5)

=−5c5+−15a+−25b+10

Answer:

=−5c5−15a−25b+10

The ratio of the lengths of the radil of two spheres is 5 : 8 what is the ratio of the surface area of the smaller sphere to the

ipn [44]

Answer:

The ratio of the small sphere’s area to that of the big one is 25:64

Step-by-step explanation:

The area of a sphere can be calculated using the formula:

A = 4 π r^2

Now, since their radii are if the ratio 5:8, we can say that the radius of the small sphere is 5 while that of the big sphere is 8

For the small sphere, the value of the area will be 4 * π * 5^2 = 100 π unit

For the big sphere, the value of the area will be 4 * π * 8^2 = 256 π unit

The ratio of the smaller sphere to the larger sphere is;

100 π : 256 π

Divide through by 4

25: 64

What is the measure of an arc intercepted by an inscribed angle whose measure is 88 degrees

I am Lyosha [343]

Answer:

$176\°$

Step-by-step explanation:

we know that

The inscribed angle is half that of the arc it comprises.

In this problem

Let

x-----> the measure of an arc intercepted by an inscribed angle

$88\°=\frac{1}{2}(x)$

$x=2(88\°)=176\°$

Draw line ST intersecting plane M at point R

Elanso [62]

The terms point, line and plane, are the undefined terms in geometry. They are so basic that these terms are used to define other terms in geometry. You can describe a point to be indicating a location or position without any thickness. A line is a series of points that travel in one direction infinitely at both ends. A plane is a flat surface of area. The diagram of line ST intersecting plane M at point R is shown in the attached picture.
