Convert the following Celsius degrees to Fahrenheit 35° F

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.

Step-by-step explanation:

Let the number of girls in club be [tex]x[/tex]

Number of boys = 30

Number of boys is 10 times half the number of girls

i.e. [tex]30 = 10(\frac{x}{2} ) = \frac{10x}{2} \\60 = 10x\\x = \frac{60}{10} \\x = 6[/tex]

Total number of boys and girls in club = 30 + 6 = 36

take a peek at the fractions in the expression, hmmmm let's see the LCD of all fractions will just be 4, in this case there's one fraction only anyway, so let's multiply both sides by that LCD of 4 to do away with the denominators

[tex]\bf 6=\cfrac{a}{4}+2\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{4}}{4(6)=4\left( \cfrac{a}{4}+2 \right)}\implies 24=a+8\implies 16=a[/tex]

Using the two given equations:

x - y = 34

x +y = 212

Rewrite the first one in terms of x:

x = 34 + y

Now replace x in the 2nd equation:

34 + y + y = 212

Simplify:

34 +2y = 212

Subtract 34 from both sides:

2y = 178

Divide both sides by 2:

y = 178/2

y = 89

Now replace y in an equation to solve for x:

x + 89 = 212

x = 212-89

x = 123

So x²(x + 2)(x - 7) ≥ 0 when x ≤ -2 or

x ≥ 7.

Answer:

178 m²

Step-by-step explanation:

You want to find A - D - B + C

A = 12 * (12 + 4) = 12 * 16 = 192

D = 4 * 8 = 32

B = 4 * 3 / 2 = 12 / 2 = 6

C = 6 * 8 / 2 = 48 / 2 = 24

192 - 32 - 6 + 24 = 160 - 6 + 24 = 154 + 24 = 178

Answer:x=-36

Step-by-step explanation:

First step: Simplify both sides of the equation by

x=1 ,so you put 1/8 and move x to the side like this 1/8x

Now you got 1/8x+1/2=-4

Step 2: Subtract 1/2 to both sides because it's the smallest constant/number

1/2-1/2=0 and -4-1/2=-9/2

-4 subtracted from 1/2 ,you put a 1 under -4, it would be like this -4/1 subtracted from 1/2

I do the butter-fly method which would be -4*2-1*1 because when you put the fractions like this -4/1-1/2 on paper then you would see why

and you multiply the denominators(bottom), so 1*2=2,and -8-1 equals -9 because -8 is larger than postive 1.

so now we have -9/2

Last step is to multiply by 8 on both sides to get rid of the 8 on the other side(left side) so x will be alone,so 8*-9/2=-36

First you will get -72/2 when you divide it you get -36

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.

Answer:Well, one of those rules is called the subtraction property of inequality, and it basically says that if you minus a number from one side of an inequality, you have to minus that same number from the other side of the inequality as well. -virtualnerd.com

Step-by-step explanation:

The Subtraction Property of Inequalities allows subtracting the same value from both sides of an inequality without altering its direction, a fundamental concept in algebra.

The Subtraction Property of Inequalities states that you can subtract the same value from both sides of an inequality without changing the inequality's direction. This property is essential in solving inequalities and maintaining the inequality relationship.

For example:

If 3 < 7, then subtracting 2 from both sides gives 1 < 5, which still holds true.

Understanding and applying this property correctly is crucial in algebra and helps in solving various mathematical problems.

Final answer:

The three numbers in question are 65, 325, and 165, found by setting up an equation based on the given relationships and solving for the first number.

Explanation:

Finding the Three Numbers

Let's denote the first number as x. According to the problem, the second number is 5 times the first number, which can be written as 5x. The third number is 100 more than the first number and can be represented as x + 100. The sum of these three numbers equals 555, so we can set up the following equation to solve for x:

x + 5x + (x + 100) = 555

Combining like terms, we get:

7x + 100 = 555

Subtracting 100 from both sides gives us:

7x = 455

Now divide both sides by 7:

x = 65

The first number is 65. Using this value, we can find the second number:

5x = 5 × 65 = 325

And the third number:

x + 100 = 65 + 100 = 165

Therefore, the three numbers are 65, 325, and 165.

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.

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}
