Answer:

11/25

Step-by-step explanation:

15 red, 13 blue, and 50 total. Therefore, yellow = 50-15-13=22.

Probability (yellow) = 22/50 = 11/25

Answer:

[tex]\frac{11}{25}[/tex] chance

In percent form;

44%

Step-by-step explanation:

1. Approach

First, one must find the amount of yellow marbles in the bag. This can be done by subtracting the amount of red and blue marbles from the total marbles in the bag. Then one will set up a proportion and solve to find out the probability of choosing a yellow marble. Remember, probability is [tex]\frac{desired_{.}outcomes}{total_{.}outcomes}[/tex]

2. Find the amount of yellow marbles

Subtract the number of red and blue marbles from the total marbles in the bag;

[tex]total_{.}marbles-(red+blue)\\\\=50-(15+13)\\\\=50-28\\\\=22[/tex]

There are [tex]22[/tex] yellow marbles.

3. Find the probability of selecting a yellow marble

Remember, probability is [tex]\frac{desired_{.}outcomes}{total_{.}outcomes}[/tex] and a percent is out of 100. Using this knowledge one can set up a proportion in the format;

[tex]\frac{desired_{.}outcomes}{total_{.}outcomes} = \frac{percent}{100}[/tex]

Substitute;

[tex]\frac{22}{50}=\frac{percent}{100}[/tex]

Simplify,

[tex]\frac{11}{25}=\frac{percent}{100}[/tex]

Cross products,

[tex]\frac{11}{25}=\frac{percent}{100}\\\\1100=25*(percent)\\[/tex]

Inverse operations;

[tex]1100=25*(percent)\\/25\\\\44=percent[/tex]

Step-by-step explanation:

Answer:

1/52

Step-by-step explanation:

We are given that

Total number of cards=52

Number of cards of 4 of spade=1

We have to find the probability of choosing the "4 of spades".

We know that

Probability, P(E)=[tex]\frac{number\;of\;favorable\;cases}{total\;number\;of\;cases}[/tex]

Using the formula

The probability of getting 4 of spade=[tex]\frac{1}{52}[/tex]

Hence, the probability of choosing the "4 of spades"=1/52

Answer: less than 1

Step-by-step explanation:

3.6/9 = 0.4

0.4 = 4/10 or reduced, 2/5

2/5 is less than 1

Quotient means the number we have once we divide two number

3.6/9 is equal to 0.4 and if it were to be greater than 1 there wouldn't be a zero in the ones place

Answer:

1 9/10

Step-by-step explanation:

If you need this as a fraction then the answer is probably 1 9/10

The required mixed number for 1.905 is 1 905/1000  or 1 9 / 10.

Given that,
To determine the mixed fraction of 1.905.

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.

Fraction is defined as the number of compositions that constitutes the Whole.

Here,
A mixed number is a number consisting of a whole number and a proper fraction.
The given number,
= 1.905
= 1 + 0.905
= 1 + 905 / 1000
= 1 905 /1000

Thus, the required mixed number for 1.905 is 1 905/1000  or 1 9 / 10.

Step-by-step explanation:

that's wrong, and I'm here to put the correct answer

take a look at this image, because ac=25 you set dc as x and ad as 25-x, then after that, you can form the equation root of 25^2-(x5-x)^2=root of 30^2-(x)^2 using the pythaeogrem theorem. After that you would get that x=18, then after that you just apply the theorem. 30^2-18^2 root which you would then get 24.

Answer:

1260

Step-by-step explanation:

Tents: 15×54=810

Caravans: 25×18=450

450+810=1260

Answer:

$1260

Step-by-step explanation:

Campsite Fees:

Tent - $15 (per day)

Caravan - $25 (per day)

No. of Tents and Caravans today:

Tents - 54

Caravan - 18

Total fees for Tent = 15 x 54

= $810.

Total fees for Caravan = 25 x 18

= $450.

Fees altogether for Today = Total fees for Tent + Total fees for Caravan

= $810 + $450

= $1260

Answer:

1/3 or 0.3 (recurring)

Step-by-step explanation:

Let's substitute our numbers into the equation.

27 = 9x + 24             I multipled 8 by 3 in order to get 24, because x equals 3.

Now take away 24 leaving 9x on its own.

3 = 9x

Divide 9 to separate it from x.

3/9 = x

Simplify the fraction.

1/3 = x

Hi there!

b=3·b=3b

This means:

1=3, 2=6, 3=9, 4=12, 5=15, 6=18, 7=21, 8=24, and 9=27.

Multiply by 3 everytime...

if b is 3, then the expression is is 3·b or 3b.

Final Result: 3b

As, we are given :

Minutes taken to fill Sylvia's bathtub with water = b minutes

Therefore,

Minutes taken to fill 3 bathtubs like Sylvia's bathtub = 3 × b minutes = 3b minutes

Hence, Minutes taken to fill 3 bathtubs like Sylvia's bathtub are 3b minutes.

Answer:

The clock will be 50 minutes fast

Step-by-step explanation:

Proportions

It's known a clock gains time at a steady state, or constant rate.

At 10:00 AM the clock is set at the correct time and at 1:36 PM the clock shows 2:00 PM. This means in that period of time, it has gained 24 minutes.

From 10:00 AM to 1:36 PM there are 3 hours and 36 minutes, or equivalently, 3*60+36 = 216 minutes

Our clock gains time at a rate of 24 minutes each 216 minutes. This gives the ratio 24:216 = 1:9.

When the new correct time is 5:30 PM, there will have passed 7 hours and 30 minutes since 10:00 AM, or equivalently, 7*60+30 = 450 minutes.

Since the clock gains time at a ratio 1:9, the time gained is 450/9=50 minutes.

The clock will show 50 minutes more than the correct time of 5:30 PM, that is, 6:20 PM.

The clock will be 50 minutes fast

Answer:

ay bro its 39 bc the q and r together they equal 39 plus you can also solve it with the calcliqiusnatine if you know what that is hope this helps!

Step-by-step explanation:

Answer:

29 degrees.

Step-by-step explanation:

The total of a triangle is 180 degrees.

If R = 27, that means that P and Q must make up 153 degrees.

The exterior and interior angle of Q will equal 180 degrees, as that is a straight line. Therefore, do 180 - 56 = 124, which is the degree measure of Q.

Lastly, do 153 - 124 to get 29 degrees for P.

If a+b=8, b+c=10 and c+a=12, what is the value of a+b+c?

The puzzle is solved by defining each variable in terms of another variable & a number & then making substitutions. Begin by taking each sum to define one of the variables in terms of the other. (Different combinations are available, but I’ll follow the a,b,c order.)

a+b=8 becomes a=8-b

b+c=10 becomes b=10-c

c+a=12 becomes c=12-a

Now subtract two of the equations that contain the same variable. I’ll pick two that contain an a: c+a =12 & a+b=8. Subtracting the latter from the former eliminates the “a”s, leaving c-b=4. Adding b to both sides to isolate c gives c=b+4. From above we can take b=10-c to substitute for b in c=b+4, giving us c=(10-c) + 4). Simplify the right side to c=14-c, add c to both sides, giving 2c=14, & then divide both sides by 2 to obtain c=7.

Replace the c in b=10-c with 7 to

If A = B and B = C, does A = C?

In mathematics = is assumed to be a transitive relationship. Transitivity means precisely what you stated: A = B and B = C implies A = C.

While it’s possible to use = to represent a non-transitive relationship this would be considered an abuse of notation. A ~ B or R(A, B) would be a better way to express the relation in this case.

Similar assumptions are made about operators like + and *. + is generally assumed to be commutative, whereas * can be used for noncommutative operations like matrix multiplication. E.g. A * B != B * A.

Equality in programming is another story entirely.

In many languages = is the assignment operator and == is the equality operator. Assignment is not transitive - it’s not even a relation.There are cases where the equality operator doesn’t define a transitive relation.

2/3*3/4 = 1/2

Step-by-step explanation:

We read this out as "negative 15" or you could write "negative fifteen".

The negative indicates the temperature went down. It doesn't necessarily mean that the final temperature is -15 degrees.

For example, if it starts being 50 degrees F, and drops by 15 degrees, then 50+(-15) = 50-15 = 35 degrees is the temperature after that drop. It might help to use a vertical number line.
