help plss?? :) What was the main reason for the rapid growth of Tacoma, Seattle, and Spokane in the 1880s?
They had large reserves of silver.
They were part of the railroad network.
They were port cities along the Puget Sound.
They all had large immigrant populations.
Answers
Answer:
Though both Seattle and Tacoma grew at a rapid rate from 1880 to 1890, based on the strength of their timber industries, Seattle's growth as an exporter of services and manufactured goods continued for another two decades, while Tacoma's growth dropped almost to zero.

Dan draws a circle with a radius of 8 inches. Question 1 Part A: What is the circumference of Dan's circle, inches? If needed, round your answer to the nearest hundredth. Enter your answer in the box.
Answers
Answer:
The circumference of Dan's circle is approximately 50.27 inches.
Step-by-step explanation:
The length of the circumference ([tex]s[/tex]), measured in inches, is determined by the formula:
[tex]s = 2\pi\cdot r[/tex] (1)
Where [tex]r[/tex] is the radius, measured in inches.
If we know that [tex]r = 8\,in[/tex], then the length of the circumference is:
[tex]s = 2\pi\cdot (8\,in)[/tex]
[tex]s \approx 50.27\,in[/tex]
The circumference of Dan's circle is approximately 50.27 inches.

Simon invested an amount of money in a savings account at 0.5% per annum compound interest. At the end of 3 years, the amount of money in the savings account was £12180.90 Work out how much money Simon invested in the savings account.
Answers
Answer:
£12000
Step-by-step:
x*1.005³=12180.9
12180.9/1.005³ = 11999.998
=£12000
The amount of money Simon invested in the savings account is £12000.06
The formula for calculating the compound interest is expressed as:
A = P(1+r)^t where;
A is the amount after 3 years = £12180.90
P is the amount invested (principal)
r is the rate = 0.5% = 0.005
t is the time (in years) = 3years
Substitute the given values into the formula as shown:
12180.90 = P(1+0.005)^3
12180.90 = P(1.005)^3
12180.90 = 1.01508P
P = 12180.90/1.01508
P = 12,000.06
This shows that the amount of money Simon invested in the savings account is £12000.06

John is 5 feet tall and casts a shadow that is 12 feet tall. The building he is standing next to is 25 feet tall. How many feet would the shadow of the building be?
Answers
Answer:
The building's shadow will be 60 feet.
Step-by-step explanation:
Think of John as a vertical line, and his shadow as a horizontal line on a 90 degree angle, and well as the building and it's shadow.
This is a proportions problem, so you want to match the similar items, right? John and the building are similar, and the two shadows are similar.
Now, set up fractions so you can butterfly multiply to get x, the shadow of the building. John/JohnShadow = Building/BuildingShadow. These two will equal the same thing because they are the same proportion.
5/12 = 25/x
5(x) = 12(25)
5x = 300
x = 300/5
x = 60
The building's shadow will be 60 feet. If you do the math, 5/12 = .4167, and 25/60 = .4167, so the proportions match. Hope this helps, comment if you are confused!

A flower pots space and six size they're all the same length. Each side measures X -6 units. The bases perimeter is 78 units. What is the value of X
Answers
Answer:
x = 19
Step-by-step explanation:
The shape of the flower base has six sides of equal lengths. This means that the flower base is a regular hexagon. A regular hexagon is a closed polygon with six equal sides and six equal angles.
Each side of the base measures x - 6, and the perimeter of the base is 78 units.
Length of each side = x - 6
The total length of the base = perimeter of the base.
The total length of the base is gotten by summing all the sides of the base. Since the base has 6 sides, therefore the total length of the base = 6(x - 6). Hence:
Perimeter of base = 6(x - 6)
78 = 6x - 36
6x = 78 + 36
6x = 114
x = 114 / 6
x = 19
Length of each side of base = x - 6 = 19 - 6 = 13 units

What are exponents?Exponent is a mathematical operation, written as an. Here the expression an involves two numbers, the base 'a and the exponent or power 'n'. Exponents are used to simplify algebraic expressions.
Given here: A particular type of cell doubles every hour and initially there were 4
let x be the number of hours then we have the exponential function
N= 4×2ˣ
Now for x=0 hours we have
N=4
which is the initial amount
similarly for x=1 we have
N=4×2
=8 which is double from the initial amount in hour
Thus the function that can describe the relationship is N=4(2)ˣ

Carmen got a round trampoline with an area of 432 cm squared. Her purchase came with a cover for her trampoline. What is the length of the cover that came with Carmen’s trampoline? Use 3.14 for π(pi).
a. 73.66 cm
b. 37.31 cm
c. 137.60 cm
d. 11.63 cm
Answers
Answer:
73.66 cm
Step-by-step explanation:
The area of a round trampoline is 432 cm².
We need to find the length of the cover that came with Carmen’s trampoline.
The formula for the area of a circle is given by :
A = πr²
Where
r is radius of round trampoline
[tex]r=\sqrt{\dfrac{A}{\pi}} \\\\r=\sqrt{\dfrac{432}{3.14}} \\\\r=11.72\ cm[/tex]
To find the length of the cover, we find the perimeter of Carmen’s trampoline.
Perimeter = Circumference
[tex]C=2\pi r\\\\C=2\times 3.14\times 11.72\\\\C=73.6\ cm[/tex]
So, the correct option is (a) "73.66 cm".
