What’s 20% as a fraction, 80% as a fraction and 15% as a fraction. Also, what I mean as a fraction is like 20

Mathematics

Ber [7]2 years ago
4 0

Answer:

see below

Step-by-step explanation:

Percent means out of 100

20% = 20/100 which can be simplified

20/100   Divide by 10 on top and bottom

=2/10   Divide by 2 on top and bottom

= 1/5

80% = 80/100 which can be simplified

80/100  Divide by 10 on top and bottom

= 8/10  Divide by 2 on top and bottom

=4/5

15% = 15/100   Which can be simplified

15/100  Divide by 5 on top and bottom

= 3/20

kompoz [17]

Answer:

  8m

Step-by-step explanation:

We assume you're describing a geometric sequence with first term m and common ratio 2. Then the n-th term is ...

14. Two parallel lines l and m are intersected by a transversal t. If the interior angles on same side of transversal are (2x−8)
nlexa [21]

Answer:

70° and 110°

Step-by-step explanation:

It is given that, two parallel lines l and m are intersected by a transversal t.

The interior angles on same side of transversal are (2x−8)° and (3x−7)°.

We need to find the measure of these angles.

We know that, the sum of interior angles of the same side of the  transversal is equal to 180°. So,

(2x−8)° + (3x−7)° = 180°

⇒ 5x-15=180°

⇒5x=180°+15

⇒5x=195

⇒x=39

Put x = 39 in (2x−8)°,

(2x−8)° = (2(39)-8)°

=70°

Again put x = 39 in (3x−7)°,

(3x−7)° = (3(39)-7)°

=110°

So, the measure of these angles are 70° and 110°.
