Answer:

72feet/min

Step-by-step explanation:

The following were obtained from the question:

Distance = 54 yards

But: 1yard = 3feets

Therefore, 54 yards = 54 x 3 = 162feets

Time = 135secs

Recall: 60secs = 1mins

Therefore, 135secs = 135/60 = 2.25mins

The rate of the Zebra = Distance /time

The rate of the Zebra = 162/2.25 = 72feet/min

Answer:

7 : 30

Step-by-step explanation:

this can be simplified by looking for a number that is common

we can first divide by 10 as this is common

1260/10 = 126

5400/10 = 540

we now have 126 : 540

we can divide by 2 as it is also common

126/2 = 63

540/ 2 = 270

we can also divide by 9 as its also common

63/9 = 7

270/9 = 30

Answer:

x=-4.37 or 1.37

Step-by-step explanation:

The equation whose solution is to be found is;

[tex]1 + \frac{3}{x}= \frac{6}{ {x}^{2} } [/tex]

we now multiply through by

[tex]{x}^{2} [/tex]

This implies that;

[tex]( {x}^{2})1 +({x}^{2} \times \frac{3}{x})= {x}^{2} \times \frac{6}{ {x}^{2} }[/tex]

[tex] \implies{x}^{2}+3x=6[/tex]

Subtracting - 6 from both side we obtain;

[tex] {x}^{2} + 3x - 6 = 6 - 6[/tex]

[tex] \implies{x}^{2} + 3x - 6 =0[/tex]We now obtain a quadratic equation.So, let us use quadratic formula to find the solutions.

Comparing the equation ,

[tex]{x}^{2} + 3x - 6 = 0[/tex]

to the general quadratic formula,

[tex]a {x}^{2} + bx + c = 0[/tex]

we can say that,

a=1,b=3 and c=-6

putting this in to the quadratic formula,

[tex] \implies x = \frac{ -b\pm \sqrt{{b}^{2} - 4ac} }{2a} [/tex], we obtain

[tex]x = \frac{-3\pm \sqrt{ {3}^{2} - 4(1)(-6)} }{2(1)} [/tex]

Simplifying we obtain,

[tex] x = \frac{ -3\pm \sqrt{9+24}}{2} [/tex]

[tex] \implies x = \frac{-3-\sqrt{33} }{2}or \frac{-3+\sqrt{33}}{2} [/tex]

x=-4.37 or 1.37

Answer:

  6.3

Step-by-step explanation:

The rocket hits the ground at the same speed it left, only the velocity is downward, rather than upward. That is, the change in velocity is from +100 ft/s to -100 ft/s, a total change of 200 ft/s. The change in velocity is brought about by the acceleration due to gravity, 32 ft/s/s. The time required for the observed change in velocity is ...

  (200 ft/s)/(32 ft/s²) = 6.25 s

Rounded to tenths, it takes the rocket 6.3 seconds to hit the ground.

_____

The equation for the ballistic motion of the rocket is ...

  h(t) = -1/2·gt² +v0·t

where g is 32 ft/s² and v0 is 100 ft/s. A graph of this equation shows the rocket hits the ground at 6.25 seconds, as above.

Answer:

A [[tex]\frac{1}{169}[/tex]]

Step-by-step explanation:

The probability that the first card is an Ace is [tex]\frac{4}{52}[/tex], or [tex]\frac{1}{13}[/tex], since there are 4 Aces in a 52-card deck. To pull another ace, the probability would be [tex]\frac{4}{52} \times \frac{4}{52}[/tex], which equals [tex]\frac{16}{2704}[/tex], or [tex]\frac{1}{169}[/tex].

A. 58, 13,-35,-51

Step-by-step explanation:

Start with the greatest positive number, 58. Then use the next greatest positive number, 13. When it comes to negative numbers, the number with the smaller absolute value is greater.

|-35| = 35

|-53| = 53

-35 has a smaller absolute value than -53, so -35 is greater than -53.

Answer: 3F+2F+4F+F=750

science fiction=225

mystery=150

biographies=300

fiction=75

Step-by-step explanation: To find the equation, read through the question and write down any important information, such as there are 2 twice as many mystery book as fiction books (2*fiction books=mystery books). Once you have all the information written down place it in an equation set equal to the total (750).

After you have found the equation, solve for the fiction books (F) by isolating the variable.  3F+2F+4F+F=750, 10F=750, F=750/10, F=75.

After that you plug 75 into the equation. Which would get you 3*75= 225 science fiction books 2*75= 150 mystery books and 4*75=300 biographies

To solve the problem, fantasy books (F) are used as the variable. The equation F + 3F + 2F + 4F = 750 is solved to find F = 75, leading to 75 fantasy books, 225 science fiction books, 150 mystery books, and 300 biographies.

The student is tasked with determining the number of books in each genre in a library, given certain ratios between the numbers of books in different genres. Let's use fantasy books (F) as our variable since all other genres are described in relation to fantasy books. According to the problem, there are three times as many science fiction books as fantasy books, twice as many mystery books as fantasy books, and four times as many biographies as fantasy books. The total number of books is 750.

The equation that represents the number of each type of book can be defined as:

F + 3F + 2F + 4F = 750

Combining like terms, we get:

10F = 750

Dividing both sides by 10, we find:

F = 75

Now that we have the number of fantasy books, we can calculate the numbers for other genres:

Science fiction books: 3 × 75 = 225

Mystery books: 2 × 75 = 150

Biographies: 4 × 75 = 300

Answer:

x = 25 degrees

Step-by-step explanation:

So we know that the 4x, 2x + 10°, and x - 5° and the measures of the three interior angles of the triangle. The sum of the interior angles of a triangle is 180°.

Using this, we can conclude that the sum of 4x, 2x + 10°, and x - 5° is equal to 180°.

We can write this information as the equation:

4x + (2x + 10) + (x - 5) = 180

We can use this equation to find the value of x. To find the value of x by using the equation, we need to solve for x (put the equation into the form x = _).

Solve for x:

4x + (2x + 10) + (x - 5) = 180

4x + 2x + 10 + x - 5 = 180

Combine like terms.

7x + 5 = 180

Subtract 5 from both sides to get rid of the +5 on the left side.

7x = 180 - 5

Simplify.

7x = 175

Divide both sides by 7 to get rid of the coefficient of 7 on the left side.

x = 175 ÷ 7

Simplify.

x = 25.

x would be equal to 25°.

x = 25 degrees

Answer:

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

Step-by-step explanation:

Final answer:

An arithmetic number sequence is a sequence of numbers with a constant difference between consecutive terms, known as the common difference.

Explanation:

Arithmetic Number Sequence Definition

An arithmetic number sequence is a sequence of numbers in which the difference between consecutive terms is always the same. This fixed difference is often referred to as the common difference. For example, in the sequence 2, 5, 8, 11, ..., the common difference is 3, since each term is obtained by adding 3 to the previous term. The first term in an arithmetic sequence is usually denoted by a1, the common difference by d, and the n-th term can be expressed as [tex]a_{n}[/tex]= [tex]a_{1}[/tex] + (n - 1)d.

Arithmetic sequences are a fundamental topic in algebra and are utilized to solve various real-world problems. They also form a basis for understanding more complex patterns in mathematics, such as geometric sequences and series.

Option C: 99° is the measure of angle 6

Explanation:

It is given that the measure of ∠5 is (10x-9)°

The measure of ∠7 is (9x)°

We need to determine the measure of ∠6

Since, from the diagram it is obvious that the angles 5 and 7 are vertical angles.

And, we know that the vertical angles are always equal.

Thus, we have,

              [tex]\angle 5 = \angle 7[/tex]

       [tex]10x-9=9x[/tex]

[tex]10x-9x-9=0[/tex]

           [tex]x-9=0[/tex]

                 [tex]x=9\\[/tex]

Thus, the value of x is 9.

Substituting [tex]x=9\\[/tex] in ∠5 and ∠7, we have,

[tex]\angle 5= (10x-9)^{\circ}[/tex]

    [tex]= (10(9)-9)^{\circ}[/tex]

    [tex]= (90-9)^{\circ}[/tex]

    [tex]= 81^{\circ}[/tex]

[tex]\angle 7=(9x)^{\circ}[/tex]

    [tex]=(9(9))^{\circ}[/tex]

    [tex]=81^{\circ}[/tex]

The measure of [tex]\angle 5 = 81^{\circ}[/tex] and [tex]\angle 7= 81^{\circ}[/tex]

Since, from the diagram we can see that the angles 6 and 7 are in a straight line.

And the angles in the straight line add up to 180°

Thus, we have,

[tex]\angle 6+\angle 7=180^{\circ}[/tex]

[tex]\angle 6+81^{\circ}=180^{\circ}[/tex]

         [tex]\angle 6=180^{\circ}-81^{\circ}[/tex]

         [tex]\angle 6 =99^{\circ}[/tex]

Thus, the measure of angle 6 is 99°

Therefore, Option C is the correct answer.

Answer:

C:99

Step-by-step explanation:

t is given that the measure of ∠5 is (10x-9)°

The measure of ∠7 is (9x)°

We need to determine the measure of ∠6

Since, from the diagram it is obvious that the angles 5 and 7 are vertical angles.

And, we know that the vertical angles are always equal.

Thus, we have,

\angle 5 = \angle 7∠5=∠7

10x-9=9x10x−9=9x

10x-9x-9=010x−9x−9=0

x-9=0x−9=0

\begin{lgathered}x=9\\\end{lgathered}

x=9

Thus, the value of x is 9.

Substituting \begin{lgathered}x=9\\\end{lgathered}

x=9

in ∠5 and ∠7, we have,

\angle 5= (10x-9)^{\circ}∠5=(10x−9)

∘

= (10(9)-9)^{\circ}=(10(9)−9)

∘

= (90-9)^{\circ}=(90−9)

∘

= 81^{\circ}=81

∘

\angle 7=(9x)^{\circ}∠7=(9x)

∘

=(9(9))^{\circ}=(9(9))

∘

=81^{\circ}=81

∘

The measure of \angle 5 = 81^{\circ}∠5=81

∘

and \angle 7= 81^{\circ}∠7=81

∘

Since, from the diagram we can see that the angles 6 and 7 are in a straight line.

And the angles in the straight line add up to 180°

Thus, we have,

\angle 6+\angle 7=180^{\circ}∠6+∠7=180

∘

\angle 6+81^{\circ}=180^{\circ}∠6+81

∘

=180

∘

\angle 6=180^{\circ}-81^{\circ}∠6=180

∘

−81

∘

\angle 6 =99^{\circ}∠6=99

∘

Thus, the measure of angle 6 is 99°

Therefore, Option C is the correct answer.

Answer:

D) A $1 increase in the bill is associated with a $0.14 increase in tip amount.

Step-by-step explanation:

Slope is 0.14

= change in tip/change in bill

When change in bill is $1, change in tip is $0.14

The correct interpretation of the slope in the equation y = 0.14x + 2.5 is: C) A $0.14 increase in the bill is associated with a $1 increase in tip amount. The slope (0.14) represents the rate of change, indicating that for each dollar increase in the bill x, the tip amount y increases by $0.14.

The linear model's equation y = 0.14x + 2.5 signifies that for each dollar increase in the bill x, the tip amount y rises by $0.14. The slope, 0.14, represents the rate of change in the tip amount concerning the bill.

This implies that a $1 increase in the bill corresponds to a $0.14 increase in the tip. Option C, "A $0.14 increase in the bill is associated with a $1 increase in tip amount," accurately captures this relationship.

The slope provides insights into the proportional change between the bill and tip, highlighting the linear association in the data.

Answer:

I've never done this before, but if it is balls per square foot, then i can figure it out. It is 2 balls per square foot

Step-by-step explanation:

If the gym is 100 ft by 60 ft, it will be 6,000 square ft. Since there are 12,000 balls, you divide it by 6,000 (12,000/6,000), which is 2, so it would be 2 balls per square foot

The population density of the balls in the gym is calculated by dividing the total number of balls (12,000) by the gym's area (6,000 square feet), resulting in 2 balls per square foot.

The question asks for the population density of the balls in a gym that measures 100 feet in length and 60 feet in width, with a total of 12,000 balls available. First, we must calculate the total area of the gym to determine how many balls there are per square foot. The formula for the area is length × width, so the area of the gym is 100 feet × 60 feet = 6,000 square feet.

Next, to find the population density of the balls, we divide the total number of balls by the total area of the gym. Therefore, the population density is 12,000 balls ÷ 6,000 square feet = 2 balls per square foot. This calculation offers a simple way to visualize how densely the balls are distributed throughout the gym's space.
