Answer:

A = 50

B = 20

C = 110

Step-by-step explanation:

A triangle is equal to 180°

In order to find the measure of each angle, add angle A, B, and C to get 180°

If angle A = 5x, angle B = 2x and angle C = 110 then 5x + 2x + 110 = 180°

To find each angle, first solve for x:

5x + 2x + 110 = 180° start by adding like terms

7x + 110 = 180° now subtract 110 from 180

7x = 70 finally divide 7 from 70

x = 10

To find each individual angle, substitute x with 10. For example:

A = 5x

A = 5(10)

A = 50

B = 2x

B = 20

C = 110

If you were to add A, B, and C it should equal 180°

110 + 20 + 50 = 110

Ashley digs 7 holes.She puts 2 seeds in each hole.She has 3 seeds left over.How many seeds are there in all?

Semenov [28]

17 seeds are left over because in the 7 holes she puts 2 seeds in each which if you multiply it it will equal to 14 and plus the three that she has left over and if you add 14 and 3 you get 17 seeds. hope this helps!

A coordinator will select 6 songs from a list of 9 songs to compose an event's musical entertainment lineup. How many different

g100num [7]

Answer:

84 different lineups are possible

Step-by-step explanation:

The order in which the songs are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

6 musics from a set of 9. So

$C_{9,6} = \frac{9!}{6!(9-6)!} = 84$

84 different lineups are possible

How much greater is the surface area of the cube?

Soloha48 [4]

The surface area 3 times greater than the area.

6 * 2 gives the area
the surface area is by multiplying area by 3.
this means that the surface area is 3x bigger than area.
