Answer:

The Cardboard dimensions are 13cm in length and 12cm in breadth

Step-by-step explanation:

We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)

Final answer:

The dimensions of the cardboard rectangle are 5 cm by 12√2 cm.

Explanation:

To determine the dimensions of the cardboard rectangle inserted diagonally into a box with given dimensions, we first need to calculate the diagonal of the box that lies in the length-height plane. The box is 12 cm long and 12 cm high.

By using the Pythagorean theorem, we can find the length of the diagonal 'd' using the formula √(l² + h²), where 'l' is the length of the box and 'h' is the height.

In this case, 'd' = √(12² + 12²) = √(144 + 144) = √(288) = 12√2 cm.

Thus, the dimensions of the cardboard rectangle are its width, which is 5 cm (the width of the box), and its diagonal, which is 12√2 cm.

Answer: 2/3

Step-by-step explanation: We can rewrite the ratio 6 out of 9 as the fraction 6/9 by putting 6 in the position of the numerator and 9 in the position of the denominator.

Notice however, 6/9 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 6 and 9 which is 3 to get the equivalent fraction 2/3.

Therefore, the ratio 6 out of 9 can be rewritten as the fraction 2/3.

Answer:

1/6

Step-by-step explanation:

Answer: Marteen will paint 1/6 of her room today.

Step-by-step explanation:

In order to solve this equation, all you have to do is multiply how much of her room Marteen wants to paint today (2/3) by how much of that amount she wants to paint before lunch (1/4). because she wants to paint 1/4 of 2/3 of her room before lunch, you have to multiply 2/3 and 1/4. SO...

Multiply: 1/4 x 2/3 = 2/12

Simplify: 2/12 = 1/6

Answer: 1/6

Hope this helps!

Answer:

The expression consists of two factors, and each factor contains three terms.

Step-by-step explanation:

Factors are numbers that multiply. The two brackets are written stuck to each other without any symbol between them, which means they are multiplying.

(a+b+c) is the first factor.

(d+e+f) is the second factor

Terms are numbers that separated by addition or subtraction.

Inside the first bracket, the terms are "a", "b", and "c".

Inside the second bracket, the terms are "d"", "e", and "f".

Answer:

Options A, B, and D are correct.

Step-by-step explanation:

The given function is p(x) = x³ - 6x² - x + 30

Given that p(5) = 0, p(3) = 0 and p(-2) = 0

Therefore, putting x = 5, or x = 3, or x = -2, the function p(x) vanishes to zero.

Therefore, those are the roots of the given function p(x).

Hence, we can conclude that (x - 5), (x - 3) and (x + 2) are the factors of the function p(x) = x³ - 6x² - x + 30.

So, options A, B, and D are correct. (Answer)

Answer:

  -1 ± i√3

Step-by-step explanation:

You can rearrange the expression to vertex form:

  x^2 +2x +1 +3

  (x +1)^2 +3

You want to find the values of x that make this zero:

  (x +1)^2 +3 = 0 . . . . . . . set the expression equal to zero

  (x +1)^2 = -3 . . . . . . . . . subtract 3 to get the square alone

  x +1 = ±√(-3) = ±i√3 . . .take the square root

  x = -1 ±i√3 . . . . . . . . . . subtract 1

The zeros are the complex numbers -1+i√3 and -1-i√3.

Answer: x = 3

Step-by-step explanation: To solve for x in this equation, we must first isolate the term containing x which in this problem is -3x. Since 2 is being added to -3x, we subtract 2 from both sides of the equation to isolate the -3x.

On the left, the +2 and -2 cancel out and on the right -7 - 2 is -9 so we have -3x = -9. Now we can finish things off by just dividing both sides of the equation by -3. On the left the -3's cancel and on the right, -9 divided by -3 simplifies to 3. So we have x = 3.

Answer:

y= -2x + 7

Step-by-step explanation:

Answer: OPTION B.

Step-by-step explanation:

Below are shown some transformations for a function f(x):

1) If [tex]f(x)+k[/tex], the function is shifted up "k" units.

2) If [tex]f(x)-k[/tex], the function is shifted down "k" units.

In this case you have the following function, which you can call f(x):

[tex]y =f(x)= x^2 + 2[/tex]

Based on the transformations explained before, if this function is shifted down 4 units, you know that function obtained g(x) is:

[tex]g(x)= x^2 + 2-4\\\\g(x)= x^2 -2[/tex]

Therefore, the equation that will shift the graph of the function down 4 units, is:

[tex]y= x^2 -2[/tex]

Answer:

Step-by-step explanation:

There are approximately 275.59 inches in 7 meters.

To find out how many inches are in 7 meters, we will first convert meters to centimeters, and then centimeters to inches.

Since there are 100 centimeters in one meter, we can calculate:

7 meters × 100 centimeters/meter = 700 centimeters

Now, we know there are 2.54 centimeters in one inch, we can convert the 700 centimeters to inches:

700 centimeters × 1 inch/2.54 centimeters ≈ 275.59 inches

To the nearest inch, there are approximately 275.59 inches in 7 meters.

Final answer:

The ratio of legs to ears for Santa's reindeer is 2 legs/ear.

Explanation:

The question is asking for the ratio of legs to ears as it relates to Santa's reindeer. We know that Santa has 9 reindeer and reindeer typically have 4 legs and 2 ears. So the total number of legs would be 9 reindeer * 4 legs/reindeer = 36 legs. And the total number of ears would be 9 reindeer * 2 ears/reindeer = 18 ears. To find the ratio of legs to ears, we divide the number of legs by the number of ears: 36 legs / 18 ears = 2 legs/ear.

Answer:The remainder can be calculated by doing the following steps;

Step-by-step explanation:

The remainder when f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1 is 4.

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial , x - a, the remainder of that division will be equivalent to f(a).

Given that f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1

x - 1 = 0

x = 1

f(1) = 1⁴ - 5(1)³ + 3(1)² - 2(1) + 7 = 4

The remainder when f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1 is 4.

15 according to the test

Step-by-step explanation:

Answer:

The number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.

Step-by-step explanation:

Consider the provided information.

A football costs $35, a basketball costs $25  and a volleyball costs $15.

Let F represents the football, B represents the basketball and V represents the volleyball.

On a given day, the store sold 5 times as many footballs as volleyballs.

[tex]F=5V[/tex]......(1)

They  brought in a total of $3750 that day,

[tex]35F+25B+15V=3750[/tex]......(2)

The money made from basketballs alone was 4 times the money.

[tex]25B=4(15V)[/tex]......(3)

By equation 1, 2 and 3.

[tex]35(5V)+4(15V)+15V=3750[/tex]

[tex]250V=3750[/tex]

[tex]V=15[/tex]

Substitute the value of V in equation 1 and 3.

[tex]F=5(15)=75[/tex]

[tex]25B=4(15\times 15)\\B=36[/tex]

Hence, the number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.

The system of equations is as follows:

35F + 25B + 15V = 3750

1 F = 5V

25B = 60V

Let's define the variables first:

We are given the following information:

We can write the system of equations as:

35F + 25B + 15V = 3750

F = 5V

25B = 60V
