In a race, 27 our of the 50 swimmers finished in less than 57 minutes. What percent of swimmers finished the race in less than 57 minutes? Write and equivalent fraction to find the percent.

Answer:

.

Step-by-step explanation:

well let’s think about it this way. we can take the like numbers and add or subtract them right? so let’s think of all the like numbers.

3x, -2x, and 2x are like numbers

2y, and 2y are like numbers

2 and 2 are like numbers.

now that we have all of the like numbers down, lets start with the first set of numbers before the = sign.

3x+ 2y- 2x+ 2

well since we have 2 like numbers in there, let’s add those, so we have 3x + 2x, which that would give us 5x. since we have nothing else in that, out expression for that one would be 5x + 2y + 2. next one we have:

3x - 2x+ 2y+ 2

we have like factors in this one too. since we have a subtraction sign in between them, we have to take 3x - 2x which gives us 1x or x. which that expression would be (x + 2y + 2). if you have to add the expressions together the whole thing would be (6x + 4y + 4).

if the (-) is supposed to be a negative, then the problems would be, x + 2y+ 2; x + 2y + 2. which the ending would be 2x + 4y + 4. hope this helps. if i’m wrong someon correct me.

Answer:

Sabric's claims is correct because when you have a negative number the lower number, in this case -3.613 is greater than -3.630/

This question is based on the concept of inequality. Sabric claims is -3.613 > -3.63. It is true that -3.613  is more than -3.63.

Therefore, Sabric claim is true.

Given that :

Sabric claims that -3.613 > -3.63.

Jessica claims that -3.613 < -3.63.

We have to prove that which statement about each student's claim is true.

According to the question,

As we know that,

Negative sign with higher value is smaller than negative sign with lesser value.

For example: -2 is less than -1.

In given question, it is observe that,

Sabric claims is -3.613 > -3.63. It is true that -3.613  is more than -3.63.

Therefore, Sabric claim is true.

Jessica claims that -3.613 < -3.63. Therefore, Jessica claims is not true because it is observe that, -3.613 is more than that of -3.63.

Therefore, Sabric claims is true.

Answer:

[tex]a=3\text{ and } b=-17[/tex]

Step-by-step explanation:

We are given that:

[tex]5x^2+bx-12=(5x+a)(x-4)[/tex]

First, we can distribute the right-hand side:

[tex]5x(x-4)+a(x-4)[/tex]

Distribute:

[tex]=5x^2-20x+ax-4a[/tex]

Rewrite:

[tex]=5x^2+(-20+a)x-(4a)[/tex]

Since it is equivalent to the above expression, the coefficients of the variables must match. This means that:

[tex]-20+a=b\text{ and } 12=4a[/tex]

Solving for a in the second equation gives:

[tex]a=3[/tex]

Therefore:

[tex]b=-20+3=-17[/tex]

Answer:

No

Step-by-step explanation: No unit rate

Answer:

no

Step-by-step explanation:

there is no direct variation the changes in both x and y are not constant. In y, it is first 62 then it becomes 140. The change here is 78. However, for the next two numbers ( 140 and 256), the change should also be 78.  That's how you would know that it is constant and represents a direct variation. But in this case it isn't.

Answer:

there are 14,895 subscribers this year

Step-by-step explanation:

50% of 9930 is 4965, and just add 9930 to that

Answer:

14,895 I think

Step-by-step explanation:

Well 9,930 is a whole so it equals 100 percent. If we add another 100 percent you get 19,860 ( 9,930 plus 9,930) and since it is only 50 percent we add half of 100 percent which would be 4965 (9,930 divided by 2) and add it to the 100 percent because it was an increase by 50 percent.
