Answer:

area of field = 146.24 m²

Step-by-step explanation:

Total area of field = I + II + III

Total area of field = 64 + 32 + 50.24

Total area of field = 146.24 m²

Expression:

1 Meter divided by 6

Answer:

Length: 24 feet

Width: 8 feet

Step-by-step explanation:

ok so first let the width be x. so if the width is x then the length would be 2x+8. If the perimeter is 64 you would divide it by two because it goes all the way around the rectangle. so then you have 32=(2x+8)+x. then we solve for x.

32=(2x+8)+x

32=3x+8

-8   -8

------------------

24=3x

8=x

now you have x=8 so that is the width. then you have the length so then you fill x in 2*8+8 is the length and your length would be 24.

Answer:

just look for a ratio to ration it out so it will be simple

Step-by-step explanation:

Answer: 6 Hours

Step-by-step explanation:

It takes 6 hours to reach the destination when traveling at 388 mph.

Speed is the ratio of total distance traveled to the total time taken It is given by:

Speed = distance/time

Given that it takes 4 hours to reach a destination when travelling at 582mph, hence the distance is:

582 = distance / 4

distance = 2328 miles

If travelling at 388 mph, the time is:

388 = 2328 / time

time = 6 hours

Hence it takes 6 hours to reach the destination when traveling at 388 mph.

Answer:

the answer is 6

Step-by-step explanation:

speed is the ratio of total distance traveled to the total time taken It is given by: speed = distance/time

given that it takes 4 hours to reach a destination when travelling at 582 mph, hence the distance is:

582 = distance / 4

distance = 2328 miles

if travelling at 388 mph, the time is:

388 = 2328 / time

time = 6 hours

Answer:

27

Step-by-step explanation:

108/4=27

Answer:

C

Step-by-step explanation:

Volume = 0.5 * Base * Height * Length

You have to multiply by 0.5 because it is a Triangular prism

base(b) = 4.1

Height (h) = 7.2

Length (l) = 3.5

Plug in the numbers to the equation below and you get 51.66

Answer:

The range is  [tex]-0.00007 < p-value < 0.00007[/tex]

Step-by-step explanation:

From the question we are told that

    The sample size is  n =  8

    The null hypothesis is  [tex]H_o : \mu_d = 0[/tex]

     The alternative hypothesis is  [tex]H_a : \mu_d > 0[/tex]

      The test statistics is  [tex]z \approx 7.496[/tex]

      The degree of freedom is  [tex]df = 7[/tex]

Generally the p-value is mathematically represented as

       [tex]p-value = P(Z > 7.496 )[/tex]

Generally from the t distribution table

(Reference  -

danielsoper(dot)com(slash)statcalc(slash)calculator)  

the value of  [tex]P(Z > 7.496 )[/tex] at a degree of freedom 7 is

      [tex]P(Z > 7.496 ) = t_{7.496 , 7 } =0.00007[/tex]

So the range that contains the p -value is  

        [tex]-0.00007 < p-value < 0.00007[/tex]

8489.6

We know that:

[tex]T=2\\ P=7580\\ R=6\ percent[/tex]

Substitute into formula

[tex]T=2\\ P=7580\ into\ formula\\ R=6\ percent\\ F=P+prt\\ F=7580+7580rt[/tex]

Calculate

[tex]7580\times(1+0.06\times2)[/tex]

Calculate the product or quotient

[tex]7580\times(1+0.12)[/tex]

Calculate the sum or difference

[tex]7580\times1.12[/tex]

Calculate the product or quotient

[tex]8489.6[/tex]

Answer:

5/4 ÷ 3/8

Explanation:

This represents how many 3/8s are in 5/4 because that question indicates a division problem.

Answer:

See below.

Step-by-step explanation:

(-4,-1), (3,-2)

The slope is -1/7.

The y-intercept is approximately -1.5.

y=mx+b is the equation for standard slope-intercept form, with m being slope and b being y-intercept.

y=-1/7x-1.5

Answer:

[tex]175\pi \textsf{ cm}^3[/tex]

Step-by-step explanation:

Circumference of a circle:

[tex]C=2\pi r[/tex]  (where [tex]r[/tex] is the radius)

Given circumference = [tex]10\pi[/tex]

[tex]\implies 10\pi=2\pi r[/tex]

[tex]\implies r=5[/tex]

Volume of a cylinder:

[tex]V=\pi r^2h[/tex]   (where [tex]r[/tex] is the radius and [tex]h[/tex] is the height)

[tex]\implies V=\pi \cdot5^2\cdot 7[/tex]

[tex]\implies V=175\pi \textsf{ cm}^3[/tex]

Answer:

x-int (-3, 0); y-int (3, 0)

Step-by-step explanation:

The x-intersect is where the points intersect the x-axis, while the y-intersect is where the points intersect the y-axis.

Answer: X=6 AB= 52

Step-by-step explanation:

7x + 10 = 9x -2 (because the sides are equal) & solve.

subtract the 7x on both sides.

10 = 2x -2

add 2 on both sides

12 = 2x

divide by 2

x = 6

Answer:

x = 4

AB = 52

Step-by-step explanation:

The dashes on the line segments AB and BD mean that they are equal in length.

⇒ 7x + 10 = 9x - 2

Add 2 to both sides:

⇒ 7x + 10 + 2 = 9x - 2 + 2

⇒ 7x + 12 = 9x

Subtract 7x from both sides:

⇒ 7x + 12 - 7x = 9x - 7x

⇒ 12 = 2x

Divide both sides by 2:

⇒ 12 ÷ 2 = 2x ÷ 2

⇒ 6 = x

⇒ x = 6

Substitute x=6 into the expression for AB to find the length of AB:

⇒ AB = 7(6) + 10

⇒ AB = 42 + 10

⇒ AB = 52

Answer:

x = 10 or x = 5 thus: B is the answer

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - 15 x = -50

Add 225/4 to both sides:

x^2 - 15 x + 225/4 = 25/4

Write the left-hand side as a square:

(x - 15/2)^2 = 25/4

Take the square root of both sides:

x - 15/2 = 5/2 or x - 15/2 = -5/2

Add 15/2 to both sides:

x = 10 or x - 15/2 = -5/2

Add 15/2 to both sides:

Answer:  x = 10 or x = 5

Answer:

150.72 m²

Step-by-step explanation:

To find the shaded area, calculate the area of the smaller (white) circle and subtract it from the area of the larger circle.

-------------------------------------------------------------------------------------------

Formulae

(where [tex]r[/tex] is the radius of the circle)

-------------------------------------------------------------------------------------------

Area of large circle

Given:

⇒ 50.24 = 2 × 3.14 × r

⇒ r = 8 m

Therefore:

⇒ Area = 3.14 × 8²

             = 200.96 m²

-------------------------------------------------------------------------------------------

Area of small circle

Given:

⇒ 25.12 = 2 × 3.14 × r

⇒ r = 4 m

Therefore:

⇒ Area = 3.14 × 4²

             = 50.24 m²

-------------------------------------------------------------------------------------------

Area of shaded path

area = area of large circle - area of small circle

        = 200.96 - 50.24

        = 150.72 m²

-------------------------------------------------------------------------------------------
