Given :

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

To Find :

Minutes taken to fill three bathtubs like Sylvia's bathtub = ?

Solution :

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.

Answers

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]

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

Paul K. Young, Former PhD candidate in Mathematics

Answered September 28, 2016

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.

The temperature fell by 15 degrees Fahrenheit today.
Write a signed number to represent this temperature change.

Answers

Answer is   -15

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.

Step-by-step explanation:

Answer:

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.

A clock gains time at a steady rate. It is set to the correct time at
10: 00 AM. When the clock shows 2 : 00 PM, the correct time is
1: 36 PM. How many minutes fast will the clock be the next time the
correct time is 5 : 30 PM?

Answers

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

Answers

Answer:

21 m^2

Step-by-step explanation:

(5*2) + (6*2) - (1*1) = 21

Answer:
21m^2

Explanation:
First, we can find the areas of the two large rectangles.
A=lw
A=2*6
A=12m^2

A=lw
A=2*5
A=10m^2

Now, we can find the area of the small square where the two rectangles overlap. We can tell that the side lengths of the square are all equal to 1 (we know this because the side lengths of the rectangles are 1 less on one side).
A=lw
A=1*1
A=1m^2

Now, we can subtract 1m^2 from either of the two rectangles’ area we solved for earlier.

12m^2-1m^2
=11m^2

Then, we can add this area to the area of the other rectangle.

11m^2+10m^2
=21m^2

The length of a rectangle is two times its width. Find the area if its perimeter is 7 1/3

Answers

Let x be the width

width = x

Length is twice its width

length = 2x

Perimeter = length + width + length + width

Perimeter = x + 2x + x + 2x = 6x

Given that perimeter = 7 1/3

6x = 7 1/3

x = 7 1/3 ÷ 6 = 1 2/9

So width = 1 2/9

Length = 1 2/9 x 2 = 2 4/9

Area = length x width

Area = 1 2/9 x 2 4/9

Hypotenuse = y

Opposite = 9

Therefore,

Sin(45) = 9/y

y = 9/sin(45)

y = 9/(1/√2)

y = 9 × √2/1

y = 9√2

✔️To find x, let's find the adjacent side of the right triangle first, them add it to 7.
