Which of the following is an equivalent expression of 76543−4? Question 1 options: 176543−4 765434 1765434 765436

Greetings from Brasil...

Here's our problem:

[tex]\large{\frac{12^{3}}{12^{7}}}[/tex]

From potentiation properties:

Mᵃ ÷ Mᵇ = Mᵃ⁻ᵇ

division of power of the same base: I repeat the base and subtract the exponents

So, in our problem

[tex]\large{\frac{12^{3}}{12^{7}}}[/tex] = 12³ ÷ 12⁷

12³ ÷ 12⁴ = 12³⁻⁷

12⁻⁴

We also know about another property: P⁻ⁿ = (1/Pⁿ) so

12⁻⁴ = (1/12⁴)

Answer:

Step-by-step explanation:

To find a we use sine

From the question

a is the hypotenuse

17 is the opposite

Substitute the values into the above formula

That's

We have the final answer as

Answer:f(t)=4/9t — 12

Step-by-step explanation:

1. 4 is being multiplied by t first then divided by 9 not by 4/9 so there shouldn’t be any parentheses.

2. 12 is being subtracted from this so it should be 4/9t—12.

3. Final answer: f(t)= 4/9t — 12

Answer:

Height of lamppost = 23.835 ft (Approx)

Step-by-step explanation:

Given:

Man's distance from lamppost = 15 ft

Shadow length = 5 ft

Angle of elevation = 50°

Find:

Height of lamppost

Computation:

Using trigonometry application.

Total base length = 15 ft + 5 ft

Total base length = 20 ft

Tan 50° = Height of lamppost / Total base length

1.19175359 =  Height of lamppost / 20

Height of lamppost = 23.835 ft (Approx)

Answer:

Answer:

$31.25

Step-by-step explanation:

Let's set up an equation.

$220. 28 - total

$126.53 - cost for parts

3 - # of hours

? - price per hour

3h + $126.53 = $220.28

Subtract $126.53 from both sides.

3h = $93.75

Divide by 3.

h = $31.25

The mechanic charges $31.25 per hour for labor.

Hope that helps.

Answer:

B

Step-by-step explanation:

Lets convert everything to gallons.

Alpha Mart:

1 quart = 0.25 gallons

1 * 0.25 = 0.25 gallons for $1

1 / 0.25 = 4 * 1 = $4 per gallon

Beta Mart:

1 gallon for $3

Gamma Mart:

1 pint = 0.125 gallons

0.125 gallons for $0.54

1 / 0.125 = 8 * 0.54 = $4.32 per gallon

Delta Mart:

1 quart = 0.25 gallons

2 * 0.25 = 0.5 gallons for $1.86

1 / 0.5 = 2 * 1.86 = $3.72 per gallon.

As we can see from all the unit prices, Beta Mart sells milk for the cheapest price.

Best of Luck!

Answer:

Frank is wrong

Step-by-step explanation:

[tex]6(6) - 1 = 35[/tex]

35 is a multiply by 5 so it is not a prime number.

Answer:

The answer is below

Step-by-step explanation:

The angle 130° lies in the second quadrant since it is between 90° and 180°. Coterminal angles are angles that share the same initial and terminal side with an angle. For a angle, there are many coterminal angles, to find a coterminal angle all you have to add or subtract 360°.

The positive angle that is coterminal to 130° are:

130 + 360 = 490°

490 + 360 = 850°

The negative angle that is coterminal to 130° are:

130 - 360 = -230°

-230 - 360 = -590°

The terminal side of a  130° angle lies in the second quadrant.

Given angle measures  130°.

The whole graph plane is divided into four quadrants, namely first quadrant, second quadrant, third quadrant and fourth quadrant.

The first quadrant has range of angles from 0 degrees to 90 degrees.

The second quadrant has range of angles from 90 degrees to 180 degrees.

The third quadrant has range of angles from 180 degrees to 270 degrees.

The fourth quadrant has range of angles from 270 degrees to 360 degrees.

Since the given angle measures  130°, thus its plot has initial side on zero degree and terminal side on  130° in the second quadrant, as [tex]90^{\circ}< 360^{\circ} < 180^{\circ}[/tex]

Thus, we have terminal side of a 130° angle lying in the second quadrant.

Answer:

The length of the warehouse is 280 feet.

Step-by-step explanation:

Let A be the area of the warehouse floor, W be its width, and L be its length.

A = W * L

We know that the length is twice the width:

L = 2W

Substitute the second equation into the first equation and we get:

A = 2W * W

Solve for W (A = 39200):

39200 = 2W * W

39200 = 2W²

19600 = W²

W = 140

Plug that number into the second equation to get the length:

L = 2 * 140

L = 280

So the length of the warehouse is 280 feet, the width is 140 feet, and the total area is 39200 ft²

[tex]\huge \boxed{\mathrm{3780 \ cm}}[/tex]

[tex]\huge \boxed{\mathrm{37.8 \ m}}[/tex]

Step-by-step explanation:

22 students each maintain distancing of 180 centimeters apart.

1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-21-22

There are 21 spaces between the students in the line.

21 × 180

= 3780

The length of the line is 3780 centimeters.

To convert cm to m, we divide the value by 100.

[tex]\frac{3780}{100}[/tex] = 37.8

The length of the line is 37.8 meters.

.................Similarly,

We have, Length of Gap = 180 cm

➝ Total length of gaps = 180 cm × 21 = 3780 cm

Converting into m,

➝ 100 cm = 1 m

➝ 3780 cm = 3780 / 100 m

➝ 3780 cm = 37.80 m

Answer:

x = -12, a = 17

Step-by-step explanation:

You can use algebraic techniques to simplify two-step equations. They have a constant on one side of the equation and a variable with a coefficient on the other. However, for algebraic equations, most will require you to add or subtract a constant from the side with the variable.

4x + 7 = -41 can be simplified algebraically. Subtract 7 from both sides and then divide by 4.

4x + 7 = -41

4x = -48

x = -12

-4 - 2a = -38 can also be simplified algebraically. Add 4 to both sides and then divide by -2.

-4 - 2a = -38

-2a = -34

a = 17

Answer:

8    x = -12

12    a = 17

Step-by-step explanation:

8

4x + 7 = -41

4x = -41 - 7

4x = -48

x = -48/4

x = -12

probe:

4*-12 + 7 = -41

-48 + 7 = -41

12

-4 - 2a = -38

-2a = -38 + 4

-2a = -34

a = -34/-2

a = 17

probe:

-4 - 2*17 = -38

-4 - 34 = -38

Answer:

2xy and 5xy are like terms

Step-by-step explanation:

Like terms have the same number, and variables.

A is correct since it has one number and two variables of x and y.

B is wrong since 7 doesn’t have xy at the end like 2xy does.

C is wrong since -3 doesn’t have xy at the end like 5xt does.

D is right since 7 and -3 are by themselves with no variables.

Answer:

Option (C)

Step-by-step explanation:

To determine the population we use the formula,

[tex]P_n=P_0(1+r)^{n}[/tex]

Where [tex]P_n[/tex] = final population

[tex]P_0[/tex] = Initial population

r = percentage growth

Now we substitute these values in the formula,

[tex]7921=7547(1+r)^1[/tex]

[tex]\frac{7921}{7547}=(1+r)[/tex]

r = 1.0496 - 1

r = 0.0496

r = 0.05

Therefore, percentage growth of the population of Stark county is 5%.

Option (C). will be the answer.

Answer:

The correct option is;

x³ + 4·x² + 3·x  < x³ + 13·x² + 54·x + 72.

Step-by-step explanation:

The given parameters are;

The basic plan of the decorator = x wall-color options, x + 1 ceiling-colr options, and x + 3 floor options

The gold plan of the decorator = All of the basic plan options plus 3 additional options in each category

Therefore, the gold plan of the decorator = (x + 3) wall-color options, (x + 1 + 3) ceiling-color options, and (x + 3 + 3) floor options

The total number unique layouts offered by the basic plan = x × (x + 1) × (x + 3) = x³ + 4·x² + 3·x

Also, the total number unique layouts offered by the gold plan = (x + 3) × (x + 1 + 3) × (x + 3 + 3) = (x + 3) × (x + 4) × (x + 6)  = x³ + 13·x² + 54·x + 72

Which gives;

The comparison between the total number of unique layouts offered by the basic and gold plans  as x³ + 4·x² + 3·x  < x³ + 13·x² + 54·x + 72.

Answer:

Area of a parallelogram is base times height. Note that CD = AB & AD = BC

to find the height, draw a line from angle B perpendicular to the base b. Lets call the point of intersection at the base E. This constitutes a right triangle with AB as the hypotenuse. Using the law of sine to calculate the height h:

h/sin(A) = AB/sin(90°) ( sin(90°) = 1)

h = AB * sin(45°)

h = 10 * sin(45°)

Area = 14 * 10 * sin(45°) = 140 * sin(45°) ≈ 98.99 QEDexplanation:
