x = -8

Answer:

The correct option is:

The student should have switched the direction of the inequality sign to get –5> x for a final answer

Step-by-step explanation:

The students has made a mistake in the 3rd step.

We know that when we multiply or divide any negative number on both sides of the inequality, the sign of inequality  reverse its direction.

In step 3 the student divided 25 by -5 but did not  switch direction of the inequality sign.

Therefore the correct option is: The student should have switched the direction of the inequality sign to get –5> x for a final answer

Answer:

$47,386.44

Step-by-step explanation:

Given;

Dimension of the field = 725 feet by 1,021 feet

Length = 1021 ft

Breadth = 725 ft

Cost per foot = $13.57 per foot

Perimeter of the field = 2 × (length + breadth)

Perimeter = 2 × ( 1021 + 725) = 3492 ft

The cost of fencing the field is;

Cost per feet × perimeter

= $13.57 × 3492

= $47,386.44

Answer: He now has eight-fourths of the apples left.

Step-by-step explanation: If Sebastian has three whole apples and now decides to cut each apple into fourths, that is four parts, then the total number of fourths he has left can be derived as follows;

1 apple = 4 parts

3 apples = 3 x (4 parts)

3 apples = 12 parts

If Sebastian gives away four of the apples, we can now express this as;

Remainder = 12 parts - 4 parts

Remainder = 8 parts

What Sebastian had was fourths and no longer whole apples, hence from our calculation, Sebastian has eight-fourths (8 quarters, or 8 fourths) left as a fraction of his apples.

Final answer:

Sebastian cuts 3 apples into fourths, giving him 12 pieces. He gives away 4 pieces, leaving him with 8 fourths of an apple. The number of fourths left expressed as a fraction is 8/4.

Explanation:

Sebastian starts with 3 whole apples and cuts each into fourths, resulting in 3 x 4 = 12 pieces. After giving away 4 fourths of the apples, we subtract 4 from the original 12 pieces to answer the question: Which is the number of fourths Sebastian has left as a fraction?

To find out how many fourths are left, we compute 12 - 4 = 8 fourths. This can be simplified to the fraction 8/4, which equals 2 whole apples. However, since the question asks for the answer in the form of a fraction representing the fourths, we should write our final answer as 8/4.

If we were to simplify the fraction to show the number of whole apples instead of fourths, we would say that Sebastian has 2 whole apples left.

Answer:

The volume of the sphere is 14m³

Step-by-step explanation:

Given

Volume of the cylinder = [tex]21m^3[/tex]

Required

Volume of the sphere

Given that the volume of the cylinder is 21, the first step is to solve for the radius of the cylinder;

Using the volume formula of a cylinder

The formula goes thus

[tex]V = \pi r^2h[/tex]

Substitute 21 for V; this gives

[tex]21 = \pi r^2h[/tex]

Divide both sides by h

[tex]\frac{21}{h} = \frac{\pi r^2h}{h}[/tex]

[tex]\frac{21}{h} = \pi r^2[/tex]

The next step is to solve for the volume of the sphere using the following formula;

[tex]V = \frac{4}{3}\pi r^3[/tex]

Divide both sides by r

[tex]\frac{V}{r} = \frac{4}{3r}\pi r^3[/tex]

Expand Expression

[tex]\frac{V}{r} = \frac{4}{3}\pi r^2[/tex]

Substitute [tex]\frac{21}{h} = \pi r^2[/tex]

[tex]\frac{V}{r} = \frac{4}{3} * \frac{21}{h}[/tex]

[tex]\frac{V}{r} = \frac{84}{3h}[/tex]

[tex]\frac{V}{r} = \frac{28}{h}[/tex]

Multiply both sided by r

[tex]r * \frac{V}{r} = \frac{28}{h} * r[/tex]

[tex]V = \frac{28r}{h}[/tex] ------ equation 1

From the question, we were given that the height of the cylinder and the sphere have equal value;

This implies that the height of the cylinder equals the diameter of the sphere. In other words

[tex]h = D[/tex] , where D represents diameter of the sphere

Recall that [tex]D = 2r[/tex]

So, [tex]h = D = 2r[/tex]

[tex]h = 2r[/tex]

Substitute 2r for h in equation 1

[tex]V = \frac{28r}{2r}[/tex]

[tex]V = \frac{28}{2}[/tex]

[tex]V = 14[/tex]

Hence, the volume of the sphere is 14m³

Answer:

Step-by-step explanation:

We have:

[tex]Cylinder:\\\R-\text{radius}\\H=2R-\text{height}\\V_C-\text{volume};\ V_C=21m^3\\\\\text{the formula of a volume of a cylinder:}\ V=\pi R^2H\\\\V_C=\pi R^2(2R)=2\pi R^3[/tex]

[tex]Sphere:\\\R-\text{radius}\\V_S-\text{volume}\\\\\text{the formula of a volume of a sphere:}\ V=\dfrac{4}{3}\pi R^3[/tex]

[tex]Let's\ transform\ V_C:\\\\2\pi R^3=21\qquad\text{divide both sides by 2}\\\\\pi R^3=\dfrac{21}{2}\qquad\text{multiply both sides by}\ \dfrac{4}{3}\\\\\dfrac{4}{3}\pi R^3=\dfrac{21}{2}\cdot\dfrac{4}{3}\to V_S=\dfrac{(21:3)\cdot(4:2)}{(2:2)\cdot(3:3)}=\dfrac{7\cdot2}{1\cdot1}=\dfrac{14}{1}=14\ (m^3)[/tex]

Commutative Property of Multiplication

Step-by-step explanation:

Answer:

Graph 1.

Step-by-step explanation:

Th graph of [tex]y=\cos{(x-\pi)}[/tex] looks exactly like the graph of [tex]y=\cos{x}[/tex] if we shifted the axes [tex]\pi[/tex] units to the left. This has the visual effect of shifting the graph forward [tex]\pit[/tex][tex]\pi[/tex] units (imagine filming someone and panning the camera to the left; the person moves right in the camera frame).

So the point at [tex]x=0[/tex], which used to be [tex](0, \cos{0})=(0,1)[/tex] is now [tex](0,\cos{(0-\pi)})=(0,\cos{(-\pi)})=(0,-1)[/tex], which we can find on the first graph.

The graph of the cosine function is the first graph (counting from the left).

This is rather easy to see.

We do know that cos(− π) = cos (π) = -1

In this case, where:

f(x) = y = cos(x − π)

We will have:

f(0) = cos( − π) = -1

So we only need to see which graph has a y-intercept equal to -1. By looking at the graphs we can see that the only one that meets this condition is the first graph (counting from the left). So that is the correct option.

3 different committees

Step-by-step explanation:

after 3 committees are formed there will be one extra boy however without any more girls another committee cannot be formed.hope this helps!!!

Number of committees of 3 boys and 4 girls formed from the group of 10 boys and 12 girls  = 59400

The combination is defined as “An arrangement of objects where the order in which the objects are selected does not matter.” The combination means “Selection of things”, where the order of things has no importance.

Number of combinations of taking x items out of total n items

ⁿCₓ = n!/x!(n-x)!

Given,

Number of girls in group = 12

Number of boys in group = 10

Selecting 3 boys from the group

= ¹⁰C₃

= ¹⁰C₃

= 10!/3!(10 - 3)!

= 10!/3!×7!

= (10 × 9 × 8 × 7!)/(3 × 2 × 1 × 7!)

= 10 × 3 × 4

= 120

Selecting 4 girls from group

= ¹²C₄

=  12!/4!(12 - 4)!

=  12!/4!×8!

= (12 × 11 × 10 × 9 × 8!)/(4 × 3 × 2 × 1 × 8!)

= 3 × 11 × 5 × 3

= 495

Total number of committees of 3 boys and 4 girls formed from the group

= ¹⁰C₃ × ¹²C₄

= 120 × 495

= 59400

Hence, 59400 different committees can be formed from the group.

Volume of baking pan = 12 in. × 6 in. × 2.5 in. = 180 in.³

Mass of 1 cubic inch of cake mix = 0.55 ounces, therefore, the mass of cake mix that the 180 in.³ baking pan can hold is found as follows;

Amount of cake mix baking pan can hold = Volume of baking pan × Mass per cubic inch of cake mix

Amount of cake mix baking pan can hold = 180 in.³ × 0.55 ounce/in.³ = 99 ounces.

Answer:

Find the 73rd term of the arithmetic sequence -28, -41, -54, ...... -964

Step-by-step explanation:

U73 = -28 + (73 - 1)-13

U73 = -28 - 949 + 13

U73 = -964

The 73rd term of the arithmetic sequence -28, -41, -54, ... is -964, calculated using the formula of an arithmetic sequence.

The 73rd term of the arithmetic sequence -28, -41, -54, ... can be found by using the formula of arithmetic sequence which is a + (n - 1) * d, where 'a' is the first term of the sequence, 'd' is the common difference, and 'n' is the term number. Here, 'a' is -28 and 'd', the difference between the terms, is -13 because -41 - (-28) = -13.

So, plugging in these values to the formula: a + (n - 1) * d = -28 + (73 - 1) * -13 = -28 - 936 = -964. Therefore, the 73rd term of the sequence is -964.

24x11=264

264sec=4.4 minutes

youll be late by 1min 40 sec

Given that it takes 12 seconds to reach each floor, you will reach the 14th floor in 156 seconds. Compared to the total time available (180 seconds), you will be 24 seconds (or 0.4 minutes) early to your meeting.

To solve this problem, we need to determine how long it takes for you to reach each floor. If it takes you 24 seconds to reach the 3rd floor from the 1st floor, we can infer that it takes you 12 seconds to reach each floor (24 seconds/2 floors). Therefore, to reach the 14th floor from the first, it would take 12 seconds times 13 floors which equals 156 seconds.

Then, we need to convert the time given to get to the meeting, which is 3 minutes, into seconds (3 minutes * 60 seconds/minute = 180 seconds).

Subtract the required time to reach the 14th floor (156 seconds) from the total time available (180 seconds), and you will be 24 seconds early for your meeting (or 0.4 minutes, rounding to the nearest hundredth, if the time is converted back into minutes).
