Mathematics

Answer:

We know that, two quantities are proportional when they vary directly with each other.

i.e. quantities x and y are proportional when they have the relation y = kx, where k is any constant called constant of proportionality.

Since, the quantities are in relation y = kx.

So, for x = 0 we get that the value of y = 0.

As, the point ( 0,0 ) satisfies this relation i.e. it is a solution of y =  kx.

Hence, in proportional relationship, the graph will pass through ( 0,0 ).

There are 6 minutes of commercials for every 24 minutes of television. How many minutes of commercials are there in 1 hour and 3
mafiozo [28]

Answer:

16\ minutes

Step-by-step explanation:

For every 24\ minutes of television time of commercials = 6\ minutes

% of commercials \=frac{6}{24}\times 100=25\%

Now when time of television=1\ hour\ 36\ minutes=60+36=96\ minutes

25 \%\ of 96=\frac{25}{100}\times 96=\frac{96}{4}=16\ minutes

What's the largest 3-digit base 14 integer?
Mars2501 [29]
Base 10 has the ten digits: {0, 1, 2, 3, 4, 5, 6,7, 8, 9}

Base 11 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A} where A is treated as a single digit number

Base 12 has the digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B}

Base 13 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C}

Base 14 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D}

The digit D is the largest single digit of that last set. So the largest 3-digit base 14 integer is DDD which is the final answer

Note: It is similar to how 999 is the largest 3-digit base 10 integer

What is the value of x in the figure Pls help​
Murljashka [212]

Answer: x=18

im assuming that this is a right angle

so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.

so x=18

Guys help me with System of linear equations:
Leni [432]

Step 1: Add the two equations together to get just one equation.

2x + y + x - y = 5 + 1

Step 2: Simplify.

3x = 6

Step 3: Divide by 3 on both sides.

3x / 3 = 6 / 3

x = 2

Therefore, the answer is x=2
