Answer:

61.3 to infinty

Step-by-step explanation:

1. Multiple: 7(8) = 56

2. Multiple: 2(4) = 8

3. Divide: the result of step 2: 3 = 8 : 3 = 2.6666666666667 = 8/43

4. Multiple: the result of step 3: 4 = 8/3

* 4 = 8 · 4/

3 · 1

= 32/

3

5. Subtract: the result of step 1 - the result of step 4 = 56 - 32/3

= 56/1

- 32/3

= 56 · 3/1 · 3

- 32/3

= 168/3

- 32/3

= 168 - 32/3

= 136/3

6. Multiple: 2(8) = 16

7. Add: the result of step 5 + the result of step 6 = 136/3

+ 16 = 136/3

+ 16/1

= 136/3

+ 16 · 3/ 1 · 3

= 136/3

+ 48/3

= 136 + 48/3

= 184/3

Step-by-step explanation:

The feet per minute that John is travelling down 195 is 4840 feet per minute.

Average speed is the total distance travelled per time. It is determined by dividing total distance travelled by total time.

In order to convert 55 miles per hour to feet per minute, we have to know the unit of conversion :

1 mile = 5280 feet

1 hour = 60 minutes

55 x (5280 / 60) = 4840 feet per minute

Step-by-step explanation:

so, the garden seems to be rectangular.

it has a length.

and width = length - 2

I assume the fence should go all around the rectangular garden.

that means it has to cover 2 lengths and 2 widths.

fence = 2×length + 2×(length - 2) =

= 2×length + 2×length - 4 = 4×length - 4 =

= 4×(length - 1)

length = 7.5 m

so, he will need

4×(7.5 - 1) = 4×6.5 = 26 meter of fencing.

A supervisor finds the mean number of miles that the employees in a department live from work is 24. Then the correct option is B.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The z-score is given as

[tex]z = \dfrac{x-\mu }{s}\\[/tex]

x = 29

s = 3.6

z = 1.5

Then the mean will be

[tex]1.5 = \dfrac{29 - \mu }{3.6}\\\\\mu = 29 - 5.4\\\\\mu = 23.6 \approx 24[/tex]

Answer:

x > 34

Step-by-step explanation:

Let x be the width of the picture frame

It then follows that the length = x + 7

Therefore, our inequality is:

[tex]2(x+7) +2x > 150\\2x+14+2x > 150\\4x > 136\\x > 34[/tex]

For all values of x greater than 34 the perimeter is greater than 150 inches.

Answer:

x is greater than 34 inches.

Step-by-step explanation:

Let x = width, then the length = x+7 inches.

Perimeter =  2(W + L) = 2(x + x + 7) = 4x + 14 , so:

4x + 14 > 150

4x > 150 - 14

4x > 136

x > 34.

Name of the shape:

Surface Area of Right Triangular Prism:

⇒ Base x Height + Length(perimeter of the base)

There surface area of this shape is 144 cm²

#a

#b

If sides be L,B,H

Then

#c

Now

The surface area, the lateral area and the volume are, respectively:

The volume is a measure of the space occupied by the solid, the lateral area is the measure of the area occupied by lateral faces of the solid and the surface area is the area occupied by the cross section of the solid. Please notice that the volume of each prism is equal to the product of the surface area and the height of the solid and the lateral area is the sum of the areas of the lateral faces.

In this exercise we must follow these steps to obtain the required results:

Lastly, we proceed to make the corresponding calculations:

S = (10 mi)² = 100 mi²

L = 4 · (10 mi) · (5 mi) = 200 mi²

V = S · h = (100 mi²) · (5 mi) = 500 mi³

S = 0.25 π · (16 cm)² ≈ 201.062 cm²

L = π · (18 cm) · (9 cm) ≈ 508.938 cm²

V = S · h = (201.062 cm²) · (9 cm) ≈ 1809.558 cm³

S = 0.5 · (5) · (9 km) · (6.2 km) = 139.5 km²

L = (5) · (4 km) · (9 km) = 180 km²

V = S · h = (139.5 km²) · (4 km) = 558 km³

S = 0.5 · (3 km) · (4 km) = 6 km²

L = (9 km) · (3 km) + (9 km) · (4 km) + (9 km) · (5 km) = 108 km²

V = S · h = (6 km²) · (9 km) = 54 km³

The Volume of air needed for a spherical balloon of radius 4 inch and circumference 8π is 85.3 cubic inch

Given Data

Let us find radius

circumference = 2πr

8π = 2πr

8 = 2r

r = 8/2

r = 4 inch

Let us find the volume of the sphere

Volume = 4/3πr^3

Volume = 4/3* π*4^3

Volume = 4/3*π64

Volume = 256π/3

Volume = 85.3 cubic inch

Answer:

x=2.6

Step-by-step explanation:

We can use the Pythagorean theorem to find the third side

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

3^2 + x^2 = 4^2  where x is the unknown side

9 + x^2 = 16

Subtract 9 from each side

x^2 = 16-9

x^2 = 7

Take the square root of each side

sqrt(x^2) = sqrt(7)

x =2.645751311

Rounding to the nearest tenth

x = 2.6

Answer:

2.65

Step-by-step explanation:

take the length of the third side as x

so,take Pythagoras theorem

4^2=3^2+x^2

16=9+x^2

x^2=16-9

x^2=7
