a. 1.00
b. 1.11
c. 1.12
d. 1.25
e. 1.27
f. 1.45
g. 1.48
Answers
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.

The volume of a cylinder of radius 14cm is 210cm”, what is the
curved and total surface area of the cylinder.
Answers
5km
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.

Find the volume of the solid figure shown below. The area of the base is 40 square inches and the height of the figure is 7 inches
Answers
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.
What is 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

What is the experimental probability there will be **20 or more customers** on the forty-first day? Include it as fraction, decimal and percent.
Answers
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%

2 hours and 32.7 minutes. This is a good problem to become familiar with. It comes up in physics quite frequently.
Step-by-step explanation:
1 job/4 hours + 1 job / 7 hours = 1/x
1/4 + 1/7 = 1/x
(7 + 4)/28 = 1/x
11/28 = 1/x
x / 1 = 28/11
x = 2.54 hours repeating.
1 hour = 60 minutes
0.54 hours = x minutes
1/.54 = 60/x
x = 0.54 * 60
x = 32.7 minutes
