Answer:

1 [tex]\frac{11}{25}[/tex]

Step-by-step explanation:

You want to write out the fraction from the division problem.

To do this you want to know that the number that is being DIVIDED BY (or 36 in this problem) is the numerator (the number on top in the fraction) and the number DIVIDING the number that is being divided by is the denominator (or 25 in this problem).

You can then write this as the fraction [tex]\frac{36}{25}[/tex] . Next you want to change this into a mixed number to simplify the fraction. To simplify you want to do 36-25 because 36 exceeds 25. 36-25=11. Because you have 11 remaining you would keep it with the 25th fraction. The completed fraction should look like this 1 [tex]\frac{11}{25}[/tex] .

Answer:

C

Step-by-step explanation:

Given that (x + 8) is a factor of f(x), then x = - 8 is a root and thus

f(- 8) = 0

If (x+8) is a factor of f(x) then f(-8) =0 is the true statement.

" Factor is defined as an algebraic expression or a number when divided by another algebraic expression or a number without leaving remainder."

According to the question,

Given function = f(x)

Factor of f(x) = (x+ 8)

For example  [tex]f(x) = x^{2} + 12x+32[/tex]

                              [tex]= x^{2}+8x+4x+32 \\\\= (x+8) (x+4)[/tex]

(x+ 8) is a factor of f(x).

[tex]f(-8) = (-8)^{2} -64[/tex]

         [tex]= 64-64\\\\=0[/tex]

Hence, if (x+8) is a factor of f(x) then f(-8) =0 is the true statement.

P=30

Step-by-step explanation:

width = x

length = 2x

2x^2=50

/2       /2

x^2=50

[tex]\sqrt{x^{2} }[/tex] = [tex]\sqrt{25}[/tex]

x=5

width=5

length=10

2width + 2length = Perimeter

10+20=P

30=P

Final answer:

The width of the rectangle is determined to be 5 feet using the area formula, leading to a length of 10 feet. The perimeter is then calculated using the sum of twice the length and twice the width, resulting in a perimeter of 30 feet.

Explanation:

To solve for the perimeter of a rectangle where the area is 50 square feet and the length is twice the width, we first use the given information to set up an equation. Let the width be w feet. Therefore, the length will be 2w feet. The area A of a rectangle is given by the formula A = length times width, so in this case, A = 2w times w = 50.

Solving for w, we have w² = 25, which gives us w = 5 feet. The length, therefore, is 2 times 5 = 10 feet. The perimeter P of a rectangle is given by P = 2 times (length + width), so the perimeter of this rectangle is P = 2 times (10 + 5) = 30 feet.

Equation A:

6 + 3x = 3x - 3    

This equation has no solution, no matter what number you plug into the equation, it will never = each other

[if you tried simplifying more]

9 + 3x = 3x         (added 3 on both sides, then subtracted 3x on both sides)

9 = 0

Equation B:

2(4x - 1) = 8x - 2      Distribute/multiply 2 into (4x - 1)

(2)4x - (2)1 = 8x - 2

8x - 2 = 8x - 2      

This will have an infinite number of solutions because whatever number you plugged in, they would always = each other since they are the same on both sides of the equation

[simplified]

8x = 8x       (add 2 on both sides, then divide 8 on both sides)

x = x

Your answer is A

Equation A has no solution and Equation B has an infinite number of solutions.

The correct answer is D. Equation A and Equation B have no solution. Let's analyze each equation:

For Equation A, we can combine like terms and simplify it to:
6 + 3x = 3x - 3
6 = -3

Since 6 is not equal to -3, Equation A has no solution.

For Equation B, we distribute 2 to the terms inside the parentheses:
2(4x - 1) = 8x - 2
8x - 2 = 8x - 2

Both sides of the equation have the same expression, so Equation B is an identity. It means that for any value of x, both sides will always be equal. Therefore, Equation B has an infinite number of solutions.

Hence, the correct answer is D. Equation A and Equation B have no solution.

We have to find out distance travelled on each day of trip if total distance of trip is 1058 miles.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.

As per the questions ;

Jones family has a trip of 3 days.

Let's assume they travel distance of x miles on first day.

Distance they will travel on second day = x + 200 miles

Distance they will travel on third day = x - 75 miles

Total distance of trip = 1058 miles

c/9+6=14

9c=14-6

9c=8

c=8:9

c=1.125

Step-by-step explanation:

After solving this c/(-9+6) = 14 equation we get c = -42. To solve the equation c/(-9+6) = 14, we first simplify the expression inside the parentheses. (-9 + 6) equals -3.  

Therefore, the equation becomes c/(-3) = 14. To isolate the variable c, we multiply both sides of the equation by -3. This gives us c = 14 * (-3), which simplifies to c = -42.

Hence, the solution to the equation is c = -42. Remember to follow the order of operations (PEMDAS/BODMAS) when simplifying expressions and be cautious when dealing with negative signs in equations.

C. 3/8 i think.......

Answer: 7/15

Step-by-step explanation:

To ensure safe chlorine levels in the pool, the inequality |Cl - 3.25| ≤ 1.75 must be met, representing levels between 1.50 ppm and 5.00 ppm. The lifeguard found the level at 1.0 ppm, which is below the safe range, so more chlorine needs to be added.

Absolute Value Inequality for Chlorine Levels:

The county government specifies that a safe level of chlorine is within 1.75 ppm of 3.25 ppm. We can express this using an absolute value inequality to represent the acceptable range for the chlorine levels: |Cl - 3.25| ≤ 1.75. This represents that the chlorine level (Cl) can be at most 1.75 ppm above or below 3.25 ppm.

To solve this inequality, we consider both the upper and lower bounds:

Therefore, the chlorine level must be between 1.50 ppm and 5.00 ppm.

Analysis of the Chlorine Level Measurement:

As the lifeguard measures the chlorine level in the pool at 1.0 ppm, it falls below the acceptable range established by the inequality. Consequently, the lifeguard should add more chlorine to bring the concentration up to within the safe range, specifically, at least to the minimum safe level of 1.50 ppm.

Step-by-step explanation:

The company should sell each widget for $28.25, to the nearest cent.

To maximize profit, we need to find the vertex of the parabola represented by the profit equation y = -2x^2 + 113x - 497. Since the coefficient of x^2 is negative, the parabola opens downwards, and the vertex represents the maximum point. The x-coordinate of the vertex of a parabola in the form of y = ax^2 + bx + c can be found using the formula -b/2a.

For the equation y = -2x^2 + 113x - 497, a = -2 and b = 113. Plugging these values into the formula gives us: x = -113 / (2 × -2) = -113 / -4 = 28.25. Therefore, to maximize profit, the company should sell each widget for $28.25, to the nearest cent.

Answer:

30 out of 50 times.

Step-by-step explanation:

1 attempt represents 3 out of 5 times.

10 attempts equals 1 attempt x 10.

Multiply numbers 3 and 5 by 10.

3 x 10 = 30

5 x 10 = 50.

Therefore, your solution is 30 / 50 times.

Using the probability of the initial success rate (60%), if you attempt to swim across the pool without taking a breath 10 times, you are expected to succeed 6 out of 10 times.

The question you're asking involves a simple concept in mathematics known as probability. The event of you being able to swim across the pool without taking a breath has so far occurred with a probability of 3 successes out of 5 attempts, or a 60% success rate. This is essentially an application of a ratio - you have succeeded 3 times for every 5 attempts you made. We can apply this ratio to predict outcomes over a larger number of trials.

If you were to attempt to swim across the pool without taking a breath 10 times and maintain the same success rate of 60%, you would be expected to make it 6 times out of 10 (since 60% of 10 is 6). Here's the breakdown:

Calculate the success rate from the initial trials: 3/5 = 60%

Apply that success rate to a larger number of trials: 60% of 10 = 6

Note that real-life scenarios might deviate slightly due to variability, but based on the given probability, we predict 6 successful swims across the pool in 10 attempts.1
