Find the value of angle b.
Find the circumference and area of a circle with radius 7 m. Use the value 3.14 for pie, and do not round your answers
Answer:
circumference (c) = 43.96cm
Area (A) = 615.44cm²
Step-by-step explanation:
Here,
Radious (r) = 7 cm
circumference (c) = [tex]2\pi r[/tex]
= 2×3.14×7
=43.96cm
Area (A) = [tex]4\pi r^{2}[/tex]
= 4×3.14×7²
=12.56×49
= 615.44cm²
Answer:
area:153.86m²
circumfrence:43.96m

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

Any help would be great!!! Thank you
Answer:
D. ∆ABC ~ ∆DEF
Step-by-step explanation:
The triangles given shows that the three corresponding angles of both triangles are congruent to each other. This means that they have the same shape but different size.
Triangles that are congruent to each other have the same shape and the same size while triangles that have the same shape but different size are similar to each other.
Therefore, ∆ABC is similar to ∆DEF (∆ABC ~ ∆DEF).
f(4) =
If g(x) = 2, x =
Given:
The graph of two function f(x) and g(x).
To find:
The value of f(4) and the value of x if g(x)=2.
Solution:
In the given graph red curve is the graph of f(x) and the blue curve is the graph of g(x).
From the given graph it is clear that the value of the function f(x) at x=4 is -10. So,
[tex]f(4)=-10[/tex]
From the given graph, it is clear that the value of function g(x) is 2 at x=0. So,
[tex]g(x)=2,x=0[/tex]
Therefore, the value for the first blank is -10 and the value for the second blank is 0.
What number should be added to both sides of the equation to complete the square?

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

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

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
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.
