A bag contains 35 red counters only. Chen adds green counters to the bag. The probability of picking a green counter is now 0.3 How many green counters did Chen add?

Answers

Answer:

15

Step-by-step explanation:

Red counters = 35

Number of green counters = x

P(picking a green counter) = 0.3

Probability = required outcome / Total possible outcomes

Required outcome = number of green counter

Total possible outcomes = green counter + red counter

Hence,

0.3 = x / (35+x)

0.3(35 + x) = x

10.5 + 0.3x = x

10.5 = x - 0.3x

10.5 = 0.7x

x = 10.5 / 0.7

= 15

Number of green counters = 15

x/64 = 36/36

this is the answer

Answer:

C

Step-by-step explanation:

when doing proportions you have to align your fractions accordingly.

we are putting x over 64 which means that small triangle in the top and big triangle in the bottom. On the other side its going to be 36 because of the small triangle's side and in the bottom we put the big triangle's side which will be 72 because 36+36=72

Judy studied for 7/12 hours and her sister studied for 2/3 of a hour about how much time did they studied all together

Answers

So you first need to make both equivalent fractions. You do that by making the denominator the same so you need to find a common multiple between both which is 12 so you multiply 2/3 by 4 on the top and bottom to get something equivalent to 7/12. 7/12 +8/12=15/12 now you divide 15 and 12 to have it in fraction mode you’ll be getting that Judy and her sister studied for 1 hour and 25 minutes

The required time they all together spend time on the study is  1 1/4 hours.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Judy studied for 7/12 hours and her sister studied for 2/3 of an hour
Total time spend on study all together = 7 / 12 + 2 / 3
                                                           =  1 1/4 = 1.25 hour

Thus, the required time they all together spend time on the study is  1 1/4 hours.

Two angles of a triangle measure 55 and 20 what is the measure of the third angle of the triangle

Answers

Answer:

105 degrees

Step-by-step explanation:

well if we take a look at this

we know for sure that every triangle must have a total angle measurement of 180 degrees

so if we take the information we have and we add those together

55 + 20

that will give us

75

then in order to find the missing angle measurement we take the total number of degrees in a triangle and subtract the two angles together from it

180-75

giving us 105 degrees as the third measurement of the angle in the triangle

Answer:

the third measure is [tex]105[/tex]°

Step-by-step explanation:

All measures of a triangle add up to 180°

[tex]A+ B + C = 180[/tex]

[tex]20 + 55 + C = 180[/tex]

[tex]75 + C = 180[/tex]

[tex]C = 105[/tex]°

2/5 x 5/4 in fraction in its simplest form​

Answers

Answer:

The answer is 1/2. When you multiply the numerator and denominator, you get 10/20. If you divide the top and bottom by 5, you get 1/2.

The equivalent value of the fraction is A = 1/2 = 0.5

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = pq

when the value of p = 2/5

And , when the value of q = 5/4

On simplifying the equation , we get

A = ( 2/5 ) ( 5/4 )

So , the left hand side of the equation is equated to the right hand side by the value of ( 2/5 ) ( 5/4 )

A = ( 2/5 ) ( 5/4 )

A = ( 2 x 5 ) / ( 5 x 4 )

On simplifying , we get

A = 10/20

Divide by 10 on the numerator and denominator of the fraction , we get

A = 1/2

A = 0.5

Therefore , the value of A = 1/2 = 0.5

Hence , the fraction is A = 1/2 = 0.5

if an ordered pair was added to the table, which of the following pairs would result in the table becoming not a function.
Please help

Answers

Answer:

C or D

Step-by-step explanation:

✔️If the ordered pair (8, 3) was added to the table, we would have two one input value, 8, having two different outputs, 4 and 3 respectively. The table therefore ceases to be a function. Each input value in a function must have only one output value. Otherwise, it ceases to be a function.

✔️Also, if we look at other options, we would see that we also have another orders pair that can make the table not to be function anymore once it's added to the table.

The ordered pair (-3, 4), when added, will make us have one input value, -3, having two output values, 4 and 6 respectively. This will make the table not to become a function.

✔️Therefore, there are two correct options, they are C or D.
