An Native American tepee is conical tent. Find the number of skins needed to cover a teepee 10ft in diameter and 12ft high. each skin covers 15 sq. feet (use pi=3.14)
Answer:
19 skins
Step-by-step explanation:
Total surface area of the cone = πr(r+l)
r is the radius = 10ft/2 = 5ft
l is the slant height
l^2 = 12^2 + 5^2
l^2 = 144+25
l^2 = 169
l = 13ft
Get the surface area
TSA = 3.14(5)(5+13)
TSA = 15.7*18
TSA = 282.6 ft^2
If each skin covers 15 sq. feet
Number of skin needed = 282.6 /15
Number of skin needed = 18.84
Number of skin needed is approximately 19 skins

Answer:
19.3
Step-by-step explanation:
The proportion of students who own a cell phone on college campuses across the country has increased tremendously over the past few years. It is estimated that approximately 90% of students now own a cell phone. Fifteen students are to be selected at random from a large university. Assume that the proportion of students who own a cell phone at this university is the same as nationwide. Let X= the number of students in the sample of 15 who own a cell phone.
Required:
What is the appropriate distribution for X?
Answer:
Binomial, with [tex]p = 0.9, n = 15[/tex]
Step-by-step explanation:
For each student, there are only two possible outcomes, either they own a cellphone, or they do not. The probability of a student in the sample owning a cellphone is independent of whether other students own a cellphone or not. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution:
Probability of exactly x sucesses on n repeated trials, with p probability.
90% of students now own a cell phone.
This means that [tex]p = 0.9[/tex]
Fifteen students are to be selected at random from a large university.
This means that [tex]n = 15[/tex]
What is the appropriate distribution for X?
Binomial, with [tex]p = 0.9, n = 15[/tex]

The quotient of a number g and -4 is at most 5 .
Answer:
g≥-20
Step-by-step explanation:
The quotient of a number g and -4 is expressed as;
g/-4
If the quotient of a number g and -4 is at most 5, this is expressed as;
g/-4 ≤ 5
Multiply both sides by -4
g/-4 * -4 ≤ 5 * -4
g * ≥ -20
Hence the required solution is g≥-20

The area of each triangle is 70
The area of the kite is 140
Answer:
Area of each triangle is 70 cm²
The total area of the kite is 140 cm²
Step-by-step explanation:
Since the kite is broken into two congruent triangles, therefore:
Total area of the Kite = 2 × area of each triangle
✔️Area of each triangle = ½*base*height
base = 20 m
height = 7 m
Area of each triangle = ½*20*7 = 70 cm²
✔️Total area of the kite = 2(70) = 140 cm²

Answer:
b. 15.39 L
Step-by-step explanation:
Given;
reacting mass of the Nitrogen gas N₂, m = 42 g
pressure of the gas, P = 2 atm
temperature of the gas, T = 250 K
molar mass of Nitrogen, N = 14 g/mol
molar mass of Nitrogen gas N₂, M = 28 g/mol
number of moles of the given Nitrogen gas;
[tex]n = \frac{Reacting \ mass}{Molar \ mass} = \frac{m}{M} \\\\n = \frac{42 \ g}{28 \ g/mol} = 1.5 \ mol.[/tex]
The volume occupied by the Nitrogen gas can be calculated from Ideal gas law;
PV = nRT
where;
V is the volume of the gas
R is ideal gas constant = 0.0821 atm.L / mol.K
From the equation above, make V the subject of the formula;
[tex]V = \frac{nRT}{P} \\\\V = \frac{1.5\ mol. \ \times \ 0.0821 \ atm.L/mol.K \ \times \ 250 \ K}{2 \ atm} \\\\V = 15.39 \ L[/tex]
Therefore, the volume occupied by the Nitrogen gas is 15.39 L

Angela is helping her father paint a fence. She can paint 3 sections of the fence in 25 minutes. How many minutes will it take Angela to paint 12 sections of this fence?
Answer:
100 Minutes.
Step-by-step explain:
25 divided by 3 = 8.33333333333, So, 8.3 minutes to paint one section at a time. So, 8.3 x 12 = 99.6. So, 99.6 rounded since the last number is higher than 5 it would go to the next number. So, rounded its 100 minutes. 100 minutes for Angela to paint 12 sections.

20 divided 16 in fraction form (simplist form)
Answer:
1/4
Step-by-step exp
20/16=1.25=1/4
The fraction 20 divided by 16 can be expressed in simplified form as 5/4.
What is 20 divided 16 in fraction form?To simplify the fraction 20 divided by 16, we need to find the greatest common divisor (GCD) of the numerator (20) and the denominator (16) and divide both by that number. Let's break down the steps:
Step 1: Find the GCD
To find the GCD of 20 and 16, we can use the Euclidean algorithm. We start by dividing 20 by 16, which gives us a quotient of 1 and a remainder of 4. We then divide 16 by 4, resulting in a quotient of 4 and no remainder. The last nonzero remainder obtained is 4, so the GCD of 20 and 16 is 4.
Step 2: Divide by the GCD
To simplify the fraction, we divide both the numerator and denominator by the GCD of 4.
20 ÷ 4 = 5
16 ÷ 4 = 4
So, the simplified fraction is 5/4.
