A tennis coach selected 5 of the 8 players he trained to represent his coaching academy in a tournament.
Which ratio is equivalent to the ratio in this situation?
A. 15 over 21
B. 20 over 32
C. 5 over 3
D. 8 over 13
Answer:
B. 20 over 32
Step-by-step explanation:
Because if you multiply both number by 4, you will get the ratio of 20:32
Final answer:
The equivalent ratio to 5 out of 8 players selected is 20 over 32, as both ratios reduce to the same value when simplified. Options A, C, and D are not equivalent to the original ratio of 5 to 3. Therefore, option(B) is correct.
Explanation:
The question asks about equivalent ratios. The tennis coach selected 5 out of 8 players to represent his academy, so the original ratio is 5 selected to 3 not selected (since 8-5 = 3). To find an equivalent ratio, we need to find multiples of both numbers that maintain the same relationship.
Option A, which presents the ratio 15 over 21, can be reduced by dividing both numbers by 3, yielding 5 over 7. This is not equivalent because 5 selected to 3 not selected is different than 5 to 7.
Option B, the ratio of 20 over 32, can also be reduced by dividing both numbers by 4, yielding 5 over 8. This is equivalent to the original ratio of 5 to 3 since the number of selected players would be scaled similarly. Therefore, the correct answer is B. 20 over 32.
Option C, 5 over 3, presents the opposite of the original scenario, where the numerator would represent the selected players, but this ratio does not need scaling, so it's not a valid equivalent ratio in this question.
Lastly, option D, 8 over 13, does not reduce to a ratio equivalent to 5 over 3 as these numbers have no common factors with 5 and 3 respectively.
Why are there three zeros in the product of 6X 10'3
The three zeros in the product of 6 and 10^3 arise from the properties of multiplication and exponents; 10^3 results in 1000, which when multiplied by 6, gives 6000, featuring three zeros.
Explanation:The reason there are three zeros in the product of 6 and 10^3 is due to the properties of multiplication and exponents. In exponentiation, 10^3 means multiplying 10 by itself three times, which gives the result of 1000. When you multiply 6 by 1000 (the result of 10^3), it gives 6000, which has three zeros. The number of zeros in the product corresponds to the power of 10 in the original expression.

Step-by-step explanation:

B is the midpoint of AC. Given AB = 3x + 8 and BC=5x - 2; find the value of x
Answer:
x = 5
Step-by-step explanation:
Given that B is at the midpoint of AC, then
AB = BC ← substitute values
3x + 8 = 5x - 2 ( subtract 5x from both sides )
- 2x + 8 = - 2 ( subtract 8 from both sides )
- 2x = - 10 ( divide both sides by - 2 )
x = 5

How to use mental math in 56,211 -6,189 ?
In mental math, we simplify computations. For the given problem, we round 6,189 to 6,000, subtract it from 56,211 to get 50,211 and add back the amount we rounded down (189) to get the answer 50,400.
Explanation:Using mental math means finding a solution with simplified steps or approximate computation, instead of the traditional written or calculator methods.
In this problem; 56,211 - 6,189, you can use rounding to make this easier.
1. Round 6,189 to the nearest thousand, which is 6,000.
2. Subtract this from 56,211 to get 50,211.
3. However, we rounded down by 189 at the beginning. To correct this, just add 189 back to the answer, resulting in 50,400.
This method simplifies the process and lessens your risk of making errors when handling larger numbers.

For 56,211 - 6,189, rounding gives 50,000, and adding the small differences back in results in a final answer of 50,022.
To use mental math for the subtraction 56,211 - 6,189, consider the following steps:
First, round each number to the nearest thousand to simplify: 56,211 rounds to 56,000 and 6,189 rounds to 6,000.
Subtract the rounded numbers: 56,000 - 6,000 = 50,000.
Note that the actual numbers are slightly higher than their rounded values, making the difference slightly more than 50,000.
Adjust the result by calculating the exact difference between the small parts ignored during rounding. For example, the difference between 56,211 and 56,000 is 211, and
the difference between 6,189 and 6,000 is 189.
Add the small differences back into the result: 211 - 189 = 22.
Combine the simple difference with the adjustment: 50,000 + 22 = 50,022.
Therefore the final answer is 50,022

Through: (-5,3) , perp. To y=5x+2
Answer:
Slope of the given line=-5
Slope of the perpendicular line=1/5 [reciprocal with opposite sign]
Required equation is (y+4)=1/5(x+5)
5y+20=x+5
x-5y=15
Without using slope
Equation of the given line is 5x+y=3
Equation of the perpendicular line is x-5y=k [interchange the coefficient of x and y
and put opposite sign for y and equating the equation to k]
This line passes through (-5,-4)
-5+20=k therefore k=15
The required equation is x-5y=15

What is the range of the function y = 5 - 2x when the domain is {0, 1, 2, 3}?
Answer: {5, 3, 1, -1}
Step-by-step explanation:
So, domain is the x-values and range is the y-values. You're trying to find the y-values. The problem gives you the domain: {0, 1, 2, 3}. So now you plug in the x values into the equation to get the y-values.
1. y = 5 - 2(0)
y = 5
2. y = 5 - 2(1)
y = 3
3. y = 5 - 2(2)
y = 1
4. y = 5 - 2(3)
y = -1
So, now you have the y-values, or range.
{5, 3, 1, -1}

If f(x) = 5x – 2 and g(x) = 2x + 1, find (f- g)(x).
A. 3x - 3
B. 7x-3
C. 7x-1
D. 3 - 3x
Answer:
la respuesta es A. 3x - 3
Final answer:
To find (f - g)(x), subtract the function g(x) from f(x). (f - g)(x) = 3x - 3.
Explanation:
To find (f - g)(x), we need to subtract the function g(x) from f(x).
f(x) = 5x - 2
g(x) = 2x + 1
Subtracting g(x) from f(x) gives us:
(f - g)(x) = (5x - 2) - (2x + 1)
Expanding the expression:
(f - g)(x) = 5x - 2 - 2x - 1
Combining like terms:
(f - g)(x) = 3x - 3

Which expression represents a perfect square monomial and it’s square root? Check all that apply
[]121; 11
[]4x2; 2x
[]9x2-1; 3x-1
[]25x; 5x
[]49x4; 7x2
Final answer:
Final answer:
The expressions that represent a perfect square monomial and its square root are: 121 and 11 since 121 is 11 squared; 4x2 and 2x as 4x2 is the square of 2x; and 49x4 and 7x2 since 49x4 is the square of 7x2.
Explanation:
The expression that represents a perfect square monomial and its square root must fulfill a specific criterion where the expression can be written as the square of a monomial. A perfect square monomial, when factored, will give the square of a binomial, which suggests that it's been multiplied by itself. The square root of such an expression will be simply the base of that monomial.
Looking at the provided options, only certain expressions fit this definition:
121; 11 - 121 is indeed a perfect square as it's 11 squared, and its square root is 11.
4x2; 2x - Here, 4x2 is the square of 2x, making 2x its square root.
49x4; 7x2 - In this case, 49x4 is the square of 7x2, hence, 7x2 is the square root of 49x4.
The other expressions listed do not represent perfect square monomials with their respective square roots. In particular, 9x2-1 is not a monomial and 25x is not a square of a monomial.

Write this ratio as a fraction in the simplest form 2 pounds to 28 ounces
2lbs/28oz
Divide each side by 2
1lbs/14oz
The simplest form of the ratio is: 8/7. To express the ratio of 2 pounds to 28 ounces as a fraction in simplest form, we need to convert both quantities to the same unit of measurement.
Since there are 16 ounces in 1 pound, we can convert 2 pounds to ounces:
2 pounds * 16 ounces/pound = 32 ounces
Now, the ratio becomes:
32 ounces to 28 ounces
To write this ratio as a fraction in simplest form, we can divide both numbers by their greatest common divisor (GCD), which is 4 in this case:
32 ounces ÷ 4 = 8
28 ounces ÷ 4 = 7
So, the simplest form of the ratio is:
