Answer:

2.The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.

Step-by-step explanation:

A quadratic equation is any equation that can be rearranged in standard form as :

ax² + bx + c = 0

Where a, b and c are coefficients and a ≠ 0.

Since for a quadratic equation, the power of x is a non negative integer, it is considered as a polynomial. A quadratic equation is a second-degree polynomial (i.e the gratest power of x is two).

The equation  is not a quadratic equation because it cannot be rewritten as a second-degree polynomial.

We want to see which statement describes the equation x^5 + x^3 - 14 = 0.

The correct option is:

The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.

First, our equation:

x^5 + x^3 - 14 = 0.

Is a polynomial of degree 5 (the degree is equal to the maximum exponent).

Thus, this is not a quadratic equation.

Where a quadratic equation is a polynomial of degree 2.

Notice that we also can't replace x by another variable, such that it becomes a quadratic equation, then the correct statement is:

The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.

Angle 3 and angle 5 are alternate interior angles, and they are congruent.

Answer:

The value of the z-score tells you how many standard deviations you are away from the mean. ... A positive z-score indicates the raw score is higher than the mean average. For example, if a z-score is equal to +1, it is 1 standard deviation above the mean. A negative z-score reveals the raw score is below the mean average.

Answer:

Question 1, it was 4500 gallons of water in the tank

Question 2, it will take 70 minutes to fill the pool with water

Step-by-step explanation:

Question 1 explanation, just multiply 150 times the minutes

A tanker truck can fill the pool at a rate of 150 gallons per minute. It took 30 minutes to empty the tank of the truck. 4500 gallons of water is in the tank. If pool holds 10,500 gallons of water then it takes 2100 minutes of time to fill.

Two or more expressions with an Equal sign is called as Equation.

Given that,

A tanker truck can fill the pool at a rate of 150 gallons per minute.

It took 30 minutes to empty the tank of the truck.

Now we need to find number of gallons of water in the tank.

So to find it we have to multiply 150 with 30

4500 gallons of water were in the tank.

and the pool holds 10,500 gallons of water

Let us formulate a equation

Apply cross multiplication

150/30=10500/x

150x=315000

=2100 minutes

So 2100 minutes will it take to fill the pool with water.

Hence if a tanker truck can fill the pool at a rate of 150 gallons per minute. It took 30 minutes to empty the tank of the truck. 4500 gallons of water is in the tank. If pool holds 10,500 gallons of water then it takes 2100 minutes of time to fill.

Number of girls = [tex]\frac{2}{9}x +95[/tex]

Number of boys + Number of girls = total members

[tex]\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9[/tex]

x = 171

Number of boys = [tex]\frac{2}{9}*171[/tex] = 2 * 19 = 38

Number of girls = 38 + 95   = 133

There will be 7 nickels, 8 dimes, and 6 quarters of each type of coin. If there were one more dime than nickel and two more quarters than nickels.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that a newsboy has $2.65, consisting of nickels, dimes, and quarters

From the condition, the number of dimes exceeded the number of nickels by 1, and the number of quarters was equal to the number of nickels decreased by one.

Let the number of nickels, dimes, and quarters will be n, d, and q respectively.

1 × n = 5 cents

1 × d = 10 cents

1 × = 25 cent

d = n + 1

q = n – 1

As a result,

$2.65 ×100 = 265 cents.

The obtained equations are,

5n + 10d + 25q =265

d = n + 1

q = n – 1

Replace d with n + 1 and q with n - 1 in the equation

5n + 10× (n + 1) + 25 × (n - 1) = 265

5n + 10n + 10 + 25n - 25 = 265

40n -15 = 265

40n = 280

n = 280/40

n = 7 nickels

Substituting the value of n in the equation we get

d = 8 dimes

q = 6 quarters

n + d + q = 265 cents

35 cents + 80 cents + 150 cents = 265 cents

Convert the units from cents to dollars as

265 /100 = $2.65

Thus, there will be 7 nickels, 8 dimes, and 6 quarters of each type of coin. If there were one more dime than nickel and two more quarters than nickels

Answer: No, it is not rational (it is irrational)

If we had something like 7.78787878... where the "78"s go on forever, then it would be rational. This is called a repeating decimal.

Something like 7.787887888... does not have a repeating pattern. It has 7's and 8's, but the number of 8's seems to increase by 1 each time you list a 7. So this is why the given number is not rational.

Answer:

Nathaniel can travel 576 miles on 16 gallons.

Explanation:

Knowing that 10 gallons would be enough for 360 miles, we can divide 360 by 10 to get the amount of miles that can be driven for only ONE gallon.

360 divided by 10 is 36, so 36 is the amount of miles driven for one gallon. Now we can multiply 36 by 16 to get the amount for 16 gallons. 36 multiplied by 16 is 576. Nathaniel can travel 576 miles on 16 gallons.

Answer:

Linda makes 72 more cards than Paul

during the week

Step-by-step explanation:

Here, we want to know how many cards Linda makes than Paul during the week.

We proceed as follows;

From the question;

If Paul makes 1 card, then Linda has made three

Now let’s get their relationship with Aaron;

If Aaron makes 2 cards , Linda has made three

Now since Aaron made 72 cards, Let’s say Linda has made x cards

Let’s get the value of x now

To get the value of x, we simply cross multiply;

2 - 3

72 - x

2 * x = 3 * 72

x = (3 * 72)/2 = 108 cards

Now recall , for every 3 cards of Linda, Paul made only 1;

So the number of cards Paul will make if Linda makes 108 will be 108/3 = 36

So the number of more cards that Linda makes than Paul during the week will be ; 108 -36 = 72 cards

   -y    -y

x = 7 - y

Since x is alone and y is a variable & not a number, there's nothing else to do to the equation.

To find:

The ratio of the number of red roses to the number of white roses.

Solution:

Using the given information, the ratio of the number of red roses to the number of white roses is

[tex]\text{Required ratio}=\dfrac{\text{Number of red roses}}{\text{Number of white roses}}[/tex]

[tex]\text{Required ratio}=\dfrac{8}{4}[/tex]

[tex]\text{Required ratio}=\dfrac{2}{1}[/tex]

[tex]\text{Required ratio}=2:1[/tex]
