2nd option is the correct answer

Step-by-step explanation:

[tex] \angle 12[/tex] is the angle of depression from the second story window to the firefighter.

Explanation:

1. Age:

d. 40 years

EER calculated using the formula:

EER = {354 - (6.91 x a)} + b x {(9.36 x c) + (726 x d)}

where, a = age, b= physical activity, c= weight in kilograms (kg), d= height in meters (m).

= {354 - (6.91 x 40)} + 0.5 x {(9.36 x 78) + (726 x 0.14478)

=(354- 276.4) + (0.5 x 730.08) + 105.11028)

= 77.6 + 365.04 + 105.11028

= 547.75028.

BMI:

BMI = kg/m2 where kg= 78, m = 0.14478

BMI = [tex]\frac{78}{0.14478^{2} }[/tex]

BMI = 3,721.

then the other two angle are each 15°

so then BAX is 90-15=75°

Answer:

the experimental probability for 20 or more customersis 37.5%

Step-by-step explanation:

Given that

The recording of the customers would be in between 10:00 AM to 11:00 PM

In this, they have been fewer than 20 customers on 20 out of the 40 days

We need to find out the experimental probability for 20 or more customers

So,

= (40 - 25) ÷ (40)

= 15 ÷ 40

= 37.5%

Hence, the experimental probability for 20 or more customers is 37.5%

Answer:

The right answer is D ( 12 in )

Answer:1132858

Step-by-step explanation:

The total carbon dioxide the country emit over the course of the 10 year period would be 1,132,858 kilotons.

What is rate of decrease?

The rate of decrease is a constant amount of deduction from a fixed or primary amount.

Here, the carbon dioxide emits by the country per year is 130,000 kilotons.

The rate of decrease of the carbon dioxide emission per year would be 3.1%.

In the 1st year, the carbon dioxide emission = 130,000 kilotons.

In the 2nd year, the carbon dioxide emission = 130,000 × (100-3.1)/ 100 kilotons = 125,970 kilotons.

In the 3rd year, the carbon dioxide emission = 125,970 × (100-3.1)/ 100 kilotons = 122,064.93 kilotons.

In the 4th year, the carbon dioxide emission = 122,064.93 × (100-3.1)/ 100 kilotons = 118,280.92 kilotons.

In the 5th year, the carbon dioxide emission = 118,280.92 × (100-3.1)/ 100 kilotons = 114,614.21 kilotons.

In the 6th year, the carbon dioxide emission = 114,614.21 × (100-3.1)/ 100 kilotons = 111,061.17 kilotons.

In the 7th year, the carbon dioxide emission = 111,061.17 × (100-3.1)/ 100 kilotons = 107,618.27 kilotons.

In the 8th year, the carbon dioxide emission = 107,618.27 × (100-3.1)/ 100 kilotons = 104,282.1 kilotons.

In the 9th year, the carbon dioxide emission = 104,282.1 × (100-3.1)/ 100 kilotons = 101,049.35 kilotons.

In the 10th year, the carbon dioxide emission = 101,049.35 × (100-3.1)/ 100 kilotons = 97,916.82 kilotons.

Hence, total carbon dioxide emission by that country over 10 years = (130,000 + 125,970 + 122,064.93 + 118,280.92 + 114,614.21 + 111,061.17 + 107,618.27 + 104,282.1 + 101,049.35 + 97,916.82) kilotons = 1,132,857.77 kilotons ≈ 1,132,858 kilotons.

Step-by-step explanation:

The required curved surface area =30.772 cm² and the total surface area = 1261.412 cm² for the cylinder.

The volume of a cylinder of radius 14cm is 210cm².
curved and total surface area to be determined.

The cylinder is defined as a 3D solid that keeps two identical bases joined by a curved surface, at a certain distance.

Here, Volume of cylinder(V) = 210 cm²

   V=πr2h

   h = V/πr2

   h = 210/π*14²

   h = 0.34105

Area of curved surface = 2πr*h
                                       =  2*3.14*14*0.34
                                       =  30.772 cm²

The total surface area of the cylinder,
A = 2πrh+2πr²
A = 2*π*14*0.34+2*π·*14²
A = 1261.412 cm²

Thus, The required curved surface area =30.772 cm² and the total surface area = 1261.412 cm² for the cylinder.

Answer:

[tex] \displaystyle V _{ \text{cuboid}} =280 {in}^{3} [/tex]

Step-by-step explanation:

We are given the area of the base and the measure of the height of a solid figure . We want to find the volume of the figure.

Notice that the area of the base of the figure is not a perfect square. Thus, we assume the solid figure to be a cuboid.

Cuboid is a three dimensional rectangle. The dimensions of cuboid are length, width and height

Remember that

[tex] \displaystyle V _{ \text{cuboid}} = l\times w \times h[/tex]

Since the base area (l×w) is 40in² and height (h) is 7in, simply substitute:

[tex] \displaystyle V _{ \text{cuboid}} =40 \times 7[/tex]

simplify multiplication:

[tex] \displaystyle V _{ \text{cuboid}} =280[/tex]

hence,

The volume of the figure is 280 in³

The answer is x=-2

As you could see, this is a factored function.
