The ratio of boys to girls in a classroom is 2:5

Add the two numbers:

2 + 5 = 7

Divide the gotten number by the total amount

70/7 = 10

Multiply each ratio number individually with gotten amount.

10 x 2 = 20

10 x 5 = 50

The ratio of boys to girls is 20:50, with 50 of them being girls.

50 is your answer

hope this helps

Answer:0.625

Step-by-step explanation:

Given

There are two coins one is fair and another is bent

Probability of getting a head on fair coin is 0.5

Probability of getting a head on bent coin is 0.75

If both coins are tossed once

probability of getting at least one of the coin will come up tails is

$P=1-P(both\ heads)$

$P=1-0.5\times 0.75$

$P=1-0.375$

$P=0.625$

Two supplementary angles are in the ratio 3 1 : 5 find both angles

Zielflug [23.3K]

The two angles are 155 degrees and 25 degrees

<h3><u>Solution:</u></h3>

Given that two supplementary angles are in ratio 31 : 5

Let the first angle be 31a

Let the second angle be 5a

Two Angles are Supplementary when they add up to 180 degrees.

Therefore,

first angle + second angle = 180 degrees

$31a + 5a = 180\\\\36a = 180\\\\a = \frac{180}{36}\\\\a = 5$

<em><u>Therefore the angles are:</u></em>

first angle = 31a = 31(5) = 155 degrees

second angle = 5a = 5(5) = 25 degrees

Thus the two angles are 155 degrees and 25 degrees
