7. 3n + 6 = 66
8. Let n = Mayah's sister's age
let m = Mayah's age
let b = Mayah's brother's age
m = n - 2
b = n + 4
m + b + n = 26
⇒ n - 2 + n + 4 + n = 26
⇒ 3n + 2 = 26
9. 2n - 5
10. 2b - 6 = 16
11. n + 5 = 12
⇒ n = 7
12. c + 18 = 29
⇒ c = 29 - 18 = 11
13. h = 8 · 5 = 8 × 5 = 40
14. 453 + 364 + n = 1000
⇒ n = 1000 - 453 - 364
⇒ n = 183
15. 3n + 11 = 35
⇒ 3n = 35 - 11
⇒ n = 24 ÷ 3
⇒ n = 8

The function is defined as follows for the domain given.
f(x)=3x+2, domain = (-2,-1,0, 1}
What is the range?
Answer:
- 4, - 1, 2, 5
Step-by-step explanation:
To find the range, simply substitute each of the domains into the function to get the y-values.
f(-2) = 3(-2) + 2
= - 6 + 2
= - 4
f(- 1) = 3(-1) + 2
= - 3 + 2
= - 1
f(0) = 3(0) + 2
= 0 + 2
= 2
f(1) = 3(1) + 2
= 3 + 2
= 5
The range is - 4, -1, 2, 5.

Please help me on this question. What is the chicken saying in the last panel of the attached picture?
Answer:
12.6 kilograms
Step-by-step explanation:
I was going to go with 4. somethin until i noticed that in all of the pictures there are only 2 chickens so on the last picture instead of going down 2 you would go up two from the first picture.
Hope this helps. Btw it is just an educated guess.
Answer:
12.6 kgStep-by-step explanation:
Let the weight of each chicken be:
Big - b, medium - m, small - sIn the pictures we have:
b + m = 10.6 kgb + s = 8.5 kgm + s = 6.1 kgAdd all together:
2b + 2m + 2s = 10.6 + 8.5 + 6.12(b + m + s) = 25.2b + m + s = 25.2/2b + m + s = 12.6The chicken in the last panel says 12.6 kg
The answer is 12.6 kg

Answer:
#2) 6,440 kilograms
The density of steel is 8,050 kilograms per cubic meter. A construction company is using a steel beam in the shape of a rectangular prism that measures 12 meters long, 1/5 of a meter wide, and 1/3 meter deep then the mass of the steel beam is 6,440 kilograms Option b.
To find the mass of a steel beam.
Let's start by defining the variables we have:
- The density of steel, denoted by "ρ" (rho), is given as 8,050 kilograms per cubic meter (kg/m³).
- The dimensions of the steel beam are:
- Length (L) = 12 meters (m)
- Width (W) = 1/5 meter (m)
- Depth (D) = 1/3 meter (m)
We want to find the mass (m) of the steel beam. The mass of an object can be calculated using its density and volume:
M = ρ [tex]\times V[/tex]
Here, "V" represents the volume of the steel beam. The volume of a rectangular prism (like the steel beam) is calculated as:
[tex]\[ V = L \times W \times D \][/tex]
Substitute the given values:
[tex]\[ V = 12 \, \text{m} \times \frac{1}{5} \, \text{m} \times \frac{1}{3} \, \text{m} \][/tex]
[tex]\[ V = 12 \, \text{m} \times \frac{1}{5} \times \frac{1}{3} \, \text{m} \][/tex]
[tex]\[ V = \frac{12}{5} \times \frac{1}{3} \, \text{m}^3 \][/tex]
[tex]\[ V = \frac{12}{15} \, \text{m}^3 \][/tex]
[tex]\[ V = \frac{4}{5} \, \text{m}^3 \][/tex]
Now that we have the volume, we can find the mass of the steel beam using the given density:
[tex]\[ m = 8,050 \, \text{kg/m}^3 \times \frac{4}{5} \, \text{m}^3 \][/tex]
[tex]\[ m = \frac{8,050 \times 4}{5} \, \text{kg} \][/tex]
[tex]\[ m = \frac{32,200}{5} \, \text{kg} \][/tex]
[tex]\[ m = 6,440 \, \text{kg} \][/tex]
After performing the calculations, we find that the mass of the steel beam is 6,440 kilograms. Therefore, the correct answer is option Option b 6,440 kilograms.

A square is cut into identical rectangles. Find the perimeter of each rectangle if the perimeter of the square is 48 cm
Answer:
Given ,
Perimeter of square = 48 cm
In the question , it has been said that the square is cût into identical rectangles. Therefore ,
length of rectangle = side of squarebreadth of rectangle = side of square / 2To find - Perimeter of each rectangle formed by cûtting the square into half.
[tex]\huge\red{ ★\:Aᥒsᥕᥱr -}[/tex]

Please help me out with this assignment..
Answer:
(a) 3, (b) 96, (c) No
Step-by-step explanation:
(a) Since we have [tex]p = 150 - 6q^2[/tex] and [tex]p = 10q^2 + 2q[/tex], we can set up a quadratic equation by [tex]150 - 6q^2 = 10q^2 + 2q[/tex], moving all values to one side.
The equation is: [tex]16q^2 + 2q - 150 = 0[/tex].
Let's use the quadratic formula to find q,
we obtain that [tex]q = 3[/tex] or [tex]q = -3.125[/tex]
We can ignore [tex]-3.125[/tex] because supplying a negative quantity is impossible.
Hence, the answer of (a) is 3
(b) Simply substitute [tex]q = 3[/tex] into either equations given in the question to find p, and the answer of (b) is 96.
(c) We want to find if there is an exact quantity that makes the TR exactly 1500.
We substitute TR = 1500,
[tex]1500 = 85q - 2q^2[/tex]
Use the quadratic formula again, and we will find that the answer is "undefined".
As a result, there is not output level in which the total revenue is exactly 1500.

If you are only considering sides that are whole numbers, then you're basically looking for all the possible ways to multiply two numbers to get 48. In other words, we're listing all the ways to factor 48.
That list is
1*482*243*164*126*8The order for each pairing doesn't matter. Something like 3*16 is the same as 16*3.
If x and y were not positive integers, but instead positive real numbers, then x*y = 48 has infinitely many (x,y) solutions.

Find the volume of a pyramid with a square base, where the side length of the base is 10.9 m and the height of the pyramid is 4.7 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
[tex]V=186.1\ m^3[/tex]
Step-by-step explanation:
Volume of a Pyramid
The volume of a pyramid with base area Ab and height H is given by:
[tex]\displaystyle V=\frac{A_b*H}{3}[/tex]
If the base is a square of side length L, then its area is:
[tex]A_b=L^2[/tex]
Thus, substituting the above equation in the first:
[tex]\displaystyle V=\frac{L^2*H}{3}[/tex]
The side length is L=10.9 m and the height is 4.7 m, thus the volume is:
[tex]\displaystyle V=\frac{10.9^2*4.7}{3}[/tex]
[tex]\displaystyle V=\frac{558.407}{3}[/tex]
[tex]\boxed{V=186.1\ m^3}[/tex]

A^2 when a=3/4?? Thank you
Step-by-step explanation:
Given:-[tex]a = \frac{3}{4} [/tex]
Therefore,
[tex] {a}^{2} = ( { \frac{3}{4} })^{2} \\ \: \: = \frac{ {3}^{2} }{ {4}^{2} } \\ = \frac{9}{16} [/tex]
Solution:
Given:
[tex]a = \dfrac{3}{4}[/tex]
Square both sides of the given equation:
[tex]a = \dfrac{3}{4}[/tex]
[tex]\rightarrow (a)^{2} = \text{\huge{[}}\dfrac{3}{4}\text{\huge{]}}^{2}[/tex]
Simplify the equation:
[tex]\rightarrow a^{2} = \text{\huge{[}}\dfrac{3}{4}\text{\huge{]}}\text{\huge{[}}\dfrac{3}{4}\text{\huge{]}}[/tex]
[tex]\rightarrow a^{2} = \text{\huge{[}}\dfrac{3^{2} }{4^{2} }\text{\huge{]}}[/tex]
[tex]\rightarrow \boxed{a^{2} =\dfrac{9 }{16 }}[/tex]

the governor of state A earns $53,545 more than the governor of state B. If the total of their salaries is $310,365, find the salaries of each.
Answer:
Governor of State A earns $181,955 and Govermoe of State B earns $128,410
Answer:
the governor of state B = $128,410
the governor of state A = $ 181,955
Step-by-step explanation:
Lets say that:
the governor of state B = x
the governor of state A = x+$53,545
x+x+$53,545=
2x+$53,545= $310,365
2x=$256,820
x=$128,410
the governor of state A = $128,410 +$53,545 = $ 181,955
