Un pueblo tenía 13.578 habitantes en 1970. En 1988 la población se incrementó 1,5 veces con respecto a 1970 y en 2001 se incrementó 2,25 veces en relación a 1988. ¿Cuántos habitantes había en el año 2001?
Answer:
En 2001 el pueblo poseía 45.826 habitantes.
Step-by-step explanation:
Un pueblo tenía 13.578 habitantes en 1970. En 1988 la población se incrementó 1,5 veces con respecto a 1970. Para calcular entonces la población en 1988 debes realizar el siguiente cálculo:
13.578*1,5= 20.367
Por lo que en 1988 el pueblo poseía 20.367 habitantes.
En 2001 se incrementó la población 2,25 veces en relación a 1988. Para calcular entonces la población en 2001 debes realizar el siguiente cálculo:
20.367* 2,25= 45.825,75≅ 45.826
Por lo que en 2001 el pueblo poseía 45.826 habitantes.

Select all statements that show correct reasoning for finding `12\div\frac{3}{5}`. Multiply 12 by 5, then multiply by $$ Multiply 12 by 3, then divide by 5. Multiply 12 by 1/5 then multiply by 3. Multiply 12 by 5, then divide by 3.
Given:
The expression is:
[tex]12\div \dfrac{3}{5}[/tex]
To find:
The correct statement for solution of the given expression.
Solution:
We have,
[tex]12\div \dfrac{3}{5}[/tex]
If a number is divided by a fraction, then we need to multiply the reciprocal of the fraction with the number.
It can be written as
[tex]12\div \dfrac{3}{5}=12\times \dfrac{5}{3}[/tex]
[tex]12\div \dfrac{3}{5}=\dfrac{12\times 5}{3}[/tex]
[tex]12\div \dfrac{3}{5}=\dfrac{60}{3}[/tex]
[tex]12\div \dfrac{3}{5}=20[/tex]
To simplify the given expression, we need to multiply 12 by 5, then divide by 3.
Therefore, the correct option is D.

If y varies jointly as x and z and y=60 when x= 10 and z=-3, find y when x=8 and z=15.
Answer:
y = -240
Step-by-step explanation:
If y varies jointly as x and z, then y/(xz) = k where k is the constant of proportion
60/10(-3) = 60/-30 = -2 = k
Now, y/(xz) = -2
y/8(15) = -2
y/120 = -2
y = -240
Help please

The points (4, -6) and (r, 6) lie on a line with slope 3. Find the missing coordinate r.
Answer:
r = 8
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 3
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, - 6) and (x₂, y₂ ) = (r, 6)
m = [tex]\frac{6+6}{r-4}[/tex] = [tex]\frac{12}{r-4}[/tex] , then
[tex]\frac{12}{r-4}[/tex] = 3 ( multiply both sides by (r - 4))
12 = 3(r - 4) ← divide both sides by 3
4 = r - 4 ( add 4 to both sides )
8 = r
which one is a scaled copy
Answer: D
Step-by-step explanation:
I believe it’s D because a scaled copy is similar to the original shape, but with different shapes. It might be C, but however in math, to make a scaled copy, you have to multiply length number with the same number. (Example: Length is 2, so the scaled copy is 4.)
I hope you have a good day.

What is the inverse of H(x)=1/2x+3
Answer:
x=-6
Step-by-step explanation:
Answer:
[tex]h^{-1}[/tex] (x) = 2x - 6
Step-by-step explanation:
let y = h(x) and rearrange making x the subject
y = [tex]\frac{1}{2}[/tex] x + 3 ( multiply through by 2 to clear the fraction )
2y = x + 6 ( subtract 6 from both sides )
2y - 6 = x
Change y back into terms of x with x = [tex]h^{-1}[/tex] (x)
[tex]h^{-1}[/tex] (x) = 2x - 6

Expression for variable and coefficient product
In algebra:
A coefficient can be anything (number of alphabets). However, a variable is always represented with an alphabet
Having said that:
Analyze each of the options
(A) 11c
Here, we have:
[tex]Variable = c[/tex]
[tex]Coefficient = 11[/tex]
(B) 1/2 t
Here, we have:
[tex]Variable = t[/tex]
[tex]Coefficient = 1/2[/tex]
(C) 5•10
Here, 5 and 10 are not variables
(D) j•4
Here, we have:
[tex]Variable = j[/tex]
[tex]Coefficient = 4[/tex]
So, the correct options are: (A), (B) and (D)

Jenna wants to wrap a shipping box shaped like a rectangular prism. The box is 22 inches tall and has a square base with sides that each measure 3 inches. How much paper will she use?
Answer: [tex]282\ in.^2[/tex]
Step-by-step explanation:
Given
dimension of box are
[tex]h=22\ in.\\[/tex]
Square base length is [tex]l=3\ in.[/tex]
[tex]\therefore w=3\ in.[/tex]
The surface area of a rectangular prism is
[tex]S.A.=2[lb+bh+hl][/tex]
The paper area must be equal to the surface area of the prism
[tex]S.A.=2[22\times 3+3\times3 +3\times 22]\\S.A.=2\times 141=282\ in.^2[/tex]

As we know that angle of semi circle is 180°.
Here,
FLG = 40°
GLH = ?
HLJ = 60°
FLG + GLH + HLG = 180°
40° + GLH + 60° = 180°
GLH + 100° = 180°
GLH = 180° - 100°
GLH = 80°
Now,
FLH = 40° + 80° = 120°
[tex] \sf \: Length \: of \: an \: arc \: of \: GHF = \dfrac{ \theta}{360} \times 2 \pi \: r[/tex]
[tex] = \dfrac {120}{360} \times 2 \times \dfrac{22}{7} \times r[/tex]
[tex] = \frac{1}{3} \times \frac{44}{7} \times r[/tex]

Answer:
Step-by-step explanation:
.
4
2
Answer:
x = 4, -4
Step-by-step explanation:
You can do this by simply pressing the calculator OR by simplify
4x^2 - 64 = 0
(2x)^2 - 8^2 = 0
(2x - 8)(2x + 8) = 0
∴ 2x - 8 = 0 or 2x + 8 = 0
x = 4 or x = -4
Logan collected pledges for the charity walk-a-thon. He is receiving total contributions of $65 plus $20 for every mile he walks. How many miles will Logan need to walk in order to receive $325?
Answer:
Number of miles= 13
Step-by-step explanation:
Giving the following information:
He is receiving total contributions of $65 plus $20 for every mile he walks.
To calculate the number of miles to reach $325, we need to use the following formula:
Total collection= fixed contribution + variable contribution per mile*number of miles
325= 65 + 20*number of miles
260/20 = number of miles
number of miles= 13
