Answer:180

Step-by-step explanation:

Answer:

Red

Step-by-step explanation:

Let x = number of laps and Let y = time taken to complete laps

She is able to run one lap in 7 minutes

Given this information we want to create an equation

the equation would be

7x = y

Now that we have created an equation we want to find how many laps she can run in 56 minutes.

The time is represented by 7 so we plug in 56 into y

so now we have

7x = 56

Finally we solve for x

*divide each side by 7*

56/7 = 8

7x / 7 = x

we're left with x = 8 meaning that she can run 8 laps in 56 minutes

In conclusion the answer is the Red one

Answer:

Volume of big cylinder = 1,438.76 cm (Approx.)

Step-by-step explanation:

Given:

Height of smaller cylinder = 3 cm

Height of big cylinder = 6 cm

Volume of smaller cylinder = 30 cm³

Find:

Volume of big cylinder

Computation:

Volume of smaller cylinder = πr²h

(22/7)(r²)(3) = 30

Radius of small cylinder = 1.783 cm (Approx.)

So,

Radius of big cylinder = 1.783 x 2 = 3.566 cm (Approx.)

Volume of big cylinder = πr²h

Volume of big cylinder = (22/7)(3.566)²(6)

Volume of big cylinder = 1,438.76 cm (Approx.)

Answer:

Total number of bottles Bar A get = 126

Total number of bottles Bar B get = 251

Total number of bottles Bar C get = 502

Step-by-step explanation:

Given - A distributor must distribute 879 bottles of beer among 3 bars. If the order of bar A is half that of bar B and a quarter of bar C.

To find - How many bottles do each bar get?

Proof -

Let us assume that

Total number of bottles Bar A get = x

Total number of bottles Bar B get = y

Total number of bottles Bar C get = z

Now,

Given that

Total bottles distributed = 879

⇒x + y + z = 879                  ..............(1)

Now,

Given that, the order of bar A is half that of bar B and a quarter of bar C

⇒x = [tex]\frac{1}{2}y[/tex] , x = [tex]\frac{1}{4} z[/tex]

⇒y = 2x                          .............(2)

  z = 4x                          ..............(3)

Now,

Put the values of y and z in equation (1), we get

x + 2x + 4x = 879

⇒7x = 879

⇒x = [tex]\frac{879}{7}[/tex] = 125.57

⇒y = 2(125.57) = 251.14

⇒z = 4(125.57) = 502.28

∴ we get

Total number of bottles Bar A get = x = 125.57 ≈ 126

Total number of bottles Bar B get = y = 251.14 ≈ 251

Total number of bottles Bar C get = z = 502.28  ≈ 502

slope is 5/4 and y intercept is -10 from the given equation.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given equation is y=5/4x - 10

In the given equation the slope is 5/4 and y intercept is -10.

to draw the graph let us find few values

x    0      1            2          3           4

y     -10   -35/4   -30/4    -25/4    -5

Hence, slope is 5/4 and y intercept is -10 from the given equation.

Answer:

The correct option is B.

Step-by-step explanation:

From the given table it is notices that the value of y decreases as x increases, therefore it is an inverse variation.

The inverse variation is defined as

Where, k is constant of proportionality.

From the given table it is clear that the value of y is 6 at x=2.

The value of k is 12. So, the required model is

Therefore, the correct option is B.

Given:

A graph of a polynomial passes through the point (-1, 60) and has three x-intercepts: (-4,0), (1, 0), and (3, 0).

To find:

The equation of the polynomial.

Solution:

A polynomial is defined as:

[tex]P(x)=a(x-c_1)(x-c_2)...(x-c_n)[/tex]

Where, a is a constant and [tex]c_1,c_2,...,c_n[/tex] are the zeros of the polynomial.

The given polynomial has three x-intercepts (-4,0), (1, 0), and (3, 0). It means [tex]-4,1,3[/tex] are the zeroes of the given polynomial and [tex](x+4),(x-1),(x-3)[/tex] are the factors of the given polynomial.

So, the equation of the polynomial is:

[tex]P(x)=a(x+4)(x-1)(x-3)[/tex]           ...(i)

It passes through the point [tex](-1,60)[/tex].

[tex]60=a(-1+4)(-1-1)(-1-3)[/tex]

[tex]60=a(3)(-2)(-4)[/tex]

[tex]60=24a[/tex]

Divide both sides by 24.

[tex]\dfrac{60}{24}=a[/tex]

[tex]2.5=a[/tex]

Putting [tex]a=2.5[/tex] in (i), we get

[tex]P(x)=2.5(x+4)(x-1)(x-3)[/tex]  

Therefore, the equation of the given polynomial is [tex]P(x)=2.5(x+4)(x-1)(x-3)[/tex].

Step-by-step explanation:

The drone's descent can be modeled by a linear function as the rate of descent is constant.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

For this problem, we have that the drone descended 16 meters in 6 seconds, hence the slope m is given as follows:

m = -16/6 = 2.67 m/s.

As the slope is constant, a linear function can model the situation.

Answer:

20 noisemakers; 40 balloons; 5 napkins

Step-by-step explanation:

n = noisemakers amount

b = balloons amount

k = napkins amount

n/4 = k

b = 2n

b + n + k= 65

plug first and second equation into the respected variables in the 3rd equation so:

2n + n + n/4 = 65

multiple both sides by 4 to get rid of fraction

4(2n + n + n/4) = 4*65

8n + 4n + n = 260

13n = 260

n = 20

use n = 13 to get the other variables

b = 2(20)

b = 40

(20)/4 = k

k = 5

Answer:

m∠2 = 16°

Step-by-step explanation:

m∠1 + m∠2 = 90°

(Complementary angles)

74° + m∠2 = 90°

m∠2 = 90° - 74°

m∠2 = 16°

The measure of the angles 2 is 16 degrees

complementary angles sum up to 90 degrees.

Given one of the angles to be 74 degrees, hence;

m<1 + m<2 = 90 degrees

74 + m<2 = 90

m<2 = 90 - 74

m<2 = 16 degrees

Hence the measure of the angles 2 is 16 degrees

Answer:

the monthly payment is $783

Step-by-step explanation:

The computation of the monthly payment is shown below:

Given that

PV = $151,000

NPER = 30 × 12 = 360

RATE = 4.7% ÷ 12 = 0.39166

FV = $0

The formula is shown below

= PMT(RATE;NPER;-PV;FV;TYPE)

AFter applying the above formula, the monthly payment is $783.14

The function rule is f(x) = x - 12 and the complete table is

Input(x) Output(y)

32 20

14 2

6 −6

-2 -14

-10 -22

From the question, we have the following parameters that can be used in our computation:

Input(x) Output(y)

32 20

14 2

? −6

-2 -14

-10 ?

The slope is calculated as

m = (2 - 20)/(14 - 32)

m = 1

So, the equation is

y = mx + c

Using the points, we have

1(32) + c = 20

Evaluate

c = -12

So, we have

f(x) = x - 12

Using the above function, we have the following function values

f(-10) = -10 - 12 = -22

x - 12 = -6

x = 6

So, the complete table is

Input(x) Output(y)

Respuesta:

$ 750 000

Explicación paso a paso:

Precio original = $ 800,000

Si el precio original se incrementa en una cuarta parte;

(800.000 + 1/4 * 800.000) = 800.000 + 200.000 = $ 1.000.000

Nuevo precio = $ 1,000,000

Si el nuevo precio se reduce en un cuarto;

1.000.000 - 1/4 (1.000.000)

1.000.000 - 250.000

= $ 750 000

El precio final es de $ 750.000
