Answer:

width = 50 cm

Step-by-step explanation:

The volume (V) of a rectangular box is calculated as

V = lwh ( l is length, w is width and h is height )

Since V is given in cm³ then dimensions must be in cm

l = 1 m = 100 cm , then

100 × w × 75 = 375000

7500w = 375000 ( divide both sides by 7500 )

w = 50

the width of the box is 50 cm

Step-by-step explanation:

[tex]A=a^2+2a\sqrt{\frac{a^2}{4}+h^2} [/tex]is the formula that you use

h=vertical altitude and

a=side length of the base

[tex]85=5^2+(2*5)\sqrt{\frac{25}{4}+h^2}[/tex]

[tex]85-25=10\sqrt{\frac{25}{4}+h^2}[/tex]

[tex]\frac{60}{10}=\sqrt{\frac{25}{4}+h^2}[/tex]

[tex]6=\sqrt{\frac{25}{4}+h^2}[/tex]

[tex]36=\frac{25}{4}+h^2[/tex]

[tex]36-\frac{25}{4}=h^2[/tex]

[tex]36-6.25=h^2[/tex]

[tex]29.75=h^2[/tex]

Vertical altitude (h) and [tex]\frac{1}{2}a[/tex] and the slant height form a right triangle with the slant height being the hypotenuse

[tex]h^2+(2.5)^2=s^2 [/tex]where s=slant height

[tex]29.75+6.25=s^2[/tex]

[tex]36=s^2[/tex]

s=6 meters

Answer:

slant height = 6 meters

Step-by-step explanation:

surface area of pyramid: 2bs + b²

2*5*s + 5² = 85

10s = 85 - 25

10s = 60

s = 6

The slant height is 6 meters.

Answer:

sinθ=√7/4

Step-by-step explanation:

Here,

cosθ=3/4

b/h=3/4

b=3 and h=4

Using Pythagoras theorem,

h²=p²+b²

4²=p²+3²

16-9=p²

p=√7

Now,

sinθ=√7/4

The number of withholding allowances which Mario currently claim for her gross biweekly earnings of $784. 21 is 4.

Federal income tax is the tax which is used to develop and run the city or country and charged on the citizen residing there .

Mario has gross biweekly earnings of $784.21. By claiming 1 more withholding allowance, Mario would have $13 more in his take home pay.

The value $784.21 lies between $780 and $800. Here, in the problem, the Mario can claim $13 more in his take home pay.

Form, the table of Federal income tax, the calculated amount will be,

graph of the linear function y = 5 is attached below. which is true for all the values of x.

a function whose equation is of the form y = ax + b, where a and b are constants, a does not equal zero, and x is any real number, and whose graph is a straight line.

Given a linear function y = 5 here

The graph of that linear function will be a straight line that is attached below.

this function will be the same for all the values of x. since it is not dependent on the variable x

it will pass through points (0, 5),  (1, 5),  (-6, 5),  (5, 5),  (-9, 5),.... and so on.

therefore, Below is a graph of the linear function at y = 5. This holds true regardless of x's value.

a. The speed of the wind is 30 mph

b. The speed of the plane in still air is 450 mph

Let

Since the plane can travel 480 miles per hour with the wind, we have that

V + v = 480 (1)

Also, the plane travels 420 miles per hour against the​ wind, we have that

V - v = 420 (2)

The speed of the wind is 30 mph

subtracting equations (1) and (2), we have

V + v = 480 (1)

-

V - v = 420 (2)

2v = 60

v = 60/2

v = 30 mph

So, the speed of the wind is 30 mph

The speed of the plane in still air is 450 mph

Substituting v into equation (1), we have

V + v = 480 (1)

V + 30 = 480

V = 480 - 30

V = 450 mph

So, the speed of the plane in still air is 450 mph

The number of cans that can be recycled in 16 days, written in scientific notation is 2.6 x 10⁹.

The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5x 10¹².

Given to us

Average 113,204 aluminum cans are recycled in a minute.

Firstly, in order to find the number of cans that can be recycled in 16 days, we need to find the number of minutes in 16 days. we know that 1 day has 24 hours where each hour has 60 minutes. therefore,

Number of minutes in 16 days = 16 x 24 x 60

Number of minutes in 16 days = 23,040 minutes

As it is given that on an average 113,204 number of cans can be recycled in a minute, therefore,

Total number of can that can be recycled = 113,204 x 23,040

                                                                      = 2,608,220,160

                                                                       = 2.6 x 10⁹

Hence, the number of cans that can be recycled in 16 days, written in scientific notation is 2.6 x 10⁹.
