You just have to put a one for the denominator for any whole number you want to make a fraction.

Please mark me as brainliest.

If a line crosses the x-axis at (4, 0) the x-intercept is at x = 4.

The value of x for which a graph crosses the x-axis at y = 0 is the

x-intercept (a, 0).

The value of y for which a line crosses the y-axis at x = 0 is the y-intercept

(0, a).

Given, A-line crosses the x-axis at (4, 0) the x-intercept of the graph is at

x = 4 and y = 0.

Complete Question:

Yanay gets a lot of spam calls. An area code is defined to be a three digit number from 200-999 inclusive. In reality, many of these area codes are not in use, but for this question we'll simplify things and assume they all are.

Assuming each area code is just as likely as any other, what's the probability that the area code of two back to back spam calls are 804?

Answer:

1/6400 or 0.0000015625

Step-by-step explanation:

Given

Area Codes = 200 to 999 (inclusive)

Required

Determine the probability that back to back calls have area code 804

[First, we need to calculate the totality of area codes]

Total Area Codes = 999 - 200 + 1

Total Area Codes = 800

The probability of each code is 1/800

So, the probability of having back to back code of 804 is:

Probability = 1/800 * 1/800

Probability = (1/800)²

Probability = 1/640000

Hence, the required probability is 1/640000 or 0.0000015625

Answer:

15 because 3x5=15 and 60/4=15

The required number is a factor of 60 and a multiple of 3 are 12, 15, and 30.

Given that,
To determine the number is both a factor of 60 and a multiple of 3.

The factor is defined as the number that can divide another number and gives a perfect real number.

Here,
The factor of 60 are,
2 × 30 = 60
3 × 20 = 60
4 × 15 = 60
5 × 12 = 60
6 × 10 = 60
And also the number which is divisible by 3 are 12, 15, and 30.
Now the number which is a factor of 60 and divisible by 3 are 12, 15, and 30.

Thus, the required number is a factor of 60 and a multiple of 3 are 12, 15, and 30.

Answer:

It will take her 1 hour, 22 minutes, and 15 seconds.

Step-by-step explanation:

We can find how long it takes her to read one page if we take 35 divided by 20.

35/20 equals 1.75, which means it takes Lin 1.75 minutes to read 1 page.

If we multiple 1.75 times the 47 pages of the book, we get 82.25.

But, this does not mean that it takes Lin 82 minutes and 25 seconds to read the book. Since there are only 60 seconds in one minute, we must convert the .25 to seconds.

.25 is equivalent to 1/4, and 1/4 of 60 seconds is 15 seconds.

It would also look like this  [tex]\frac{1}{4} *\frac{60}{1} = \frac{60}{4} = 15[/tex]

So it took Lin 82 minutes and 15 seconds to read the book.

Or it took her 1 hour, 22 minutes, and 15 seconds to read the book.

Answer:

you have it right..25 percent of 30 is 7.5

Question: What is 25 percent of 30?

Percentage solution with steps:

Step 1: Our output value is 30.  

Step 2: We represent the unknown value with [tex]x[/tex].

Step 3: From step 1 above, [tex]30 = 100%[/tex]%.

Step 4: Similarly, [tex]x = 25[/tex]%.

Step 5: This results in a pair of simple equations:

[tex]30 = 100[/tex]% [tex](1)[/tex].

[tex]x = 25[/tex]% [tex](2)[/tex].

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both  equations have the same unit (%); we have

[tex]\frac{30}{x} = \frac{100percent}{25percent}[/tex]

Step 7: Again, the reciprocal of both sides gives

[tex]\frac{x}{30} = \frac{25}{100}[/tex]

Therefore, [tex]25[/tex]% of [tex]30[/tex] is [tex]7.5[/tex]

4x+4y=14x+4y=1 , 6x−y=1

Answer:

Step-by-step explanation:

44x + 15y = 22                    (1)

-7x + 5y +1 = 22                  Subtract 1 from this equation

-7x + 5y = 21                        (2)  Multiply this equation by 3

-21x + 15y = 63                     (3)  Subtract (1) from (3)

44x + 15y = 22

-65x = 41                             Divide by - 65

x = 41/-65                            Use this value to find y.

x = -0.6308

I can't believe anyone really gave you this.

44(41/-65) + 15y = 22

-27.75 + 15y = 22

15y = 22 + 27.75

15y = 49.75

y = 3.316

Answer: y=2x+4

Step-by-step explanation:

the line hits at 4 on the y axis and I did 2 rise, 1 run.

Answer: y = 2x+4

Step-by-step explanation:

The b-value (y-intercept; the value of y when x = 0) is 4.

The slope is rise over run, or the change in y over the change in x. The "rise" between two distinct points is 2 for every one change in space for the x-value. Thus, the slope (m) is 2.

Plug these values into the sample equation y = mx + b, and you should have your solution.
