The population density of Iceland, in people per square kilometer of land area, increased from 2.5 in 1990 to
3.3 in 2014. During this time period, the land area of Iceland was 100,250 square kilometers. By how many
people did Iceland's population increase from 1990 to 2014?
A 330,825
B 132,330
C 125,312
D 80,200
Given:
The population density of Iceland, in people per square kilometer of land area, increased from 2.5 in 1990 to 3.3 in 2014.
Land area of Iceland = 100,250 square kilometers.
To find:
The Iceland's population increase from 1990 to 2014.
Solution:
Land area of Iceland is constant, i.e., 100,250 square kilometers.
The population density of Iceland, in people per square kilometer of land area in 1990 is 2.5. So, the population in 1990 is
[tex]2.5\times 100,250=250,625[/tex]
population density of Iceland, in people per square kilometer of land area in 2014 is 3.3. So, the population in 2014 is
[tex]3.3\times 100,250=330,825[/tex]
The Iceland's population increase from 1990 to 2014 is
[tex]330,825-250,625=80,200[/tex]
Therefore, the correct option is D.
solve 2x-3< 2
please answer it fast
Answer:
x<5/2
Step-by-step explanation:
We have
2x−3<2
Add 3 to both sides.
2x−3 +3 <2 +3
which makes
2x<5
Divide both sides by 2.
2x/2 < 5/2
x<5/2

1. How far is Supermarket A from your house? (Round of your answer to the nearest whole number)
2. How far is Supermarket B from your house? (Round of your answer to the nearest whole number)
3. How far are the supermarkets from each other? (Round of your answer to the nearest whole number)
Answer:
13meters far from the supermarket
The distance between Supermarket A and Supermarket B is 35 units.
What is distance formula?The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].
From the given coordinate plane, Supermarket A is at (12, 9), House is at (0, 0) and Supermarket B at (-16, -12).
1) Distance between Supermarket A and your house is
Substitute (x₁, y₁)=(12, 9) and (x₂, y₂)=(0, 0) in distance formula, we get
Distance = √[(0-12)²+(0-9)²]
= √144+81
= √225=15 units
2) Distance between Supermarket B and your house is
Substitute (x₁, y₁)=(-16, -12) and (x₂, y₂)=(0, 0) in distance formula, we get
Distance = √[(0+16)²+(0+12)²]
= √256+144
= √400=20 units
3) Distance between Supermarket A and Supermarket B is
Substitute (x₁, y₁)=(-16, -12) and (x₂, y₂)=(12, 9) in distance formula, we get
Distance = √[(12+16)²+(9+12)²]
= √28²+21²
= √1225=35 units
Therefore, the distance between Supermarket A and Supermarket B is 35 units.

Which equation can be used to find the solution of (1/4)^y+1=64?
−y−1=3
y + 1 = 3
−y+1=3
y−1=3
Answer:
−y−1=3
Step-by-step explanation:
Which equation can be used to find the solution of (1/4)^y+1=64?
This can be solved by power of indices
(1/4)^(y+1)=64
(4^-1)^(y + 1)= 4^3
Note
(x^a)^b = x^ab
Hence:
4^(-1)(y + 1)= 4^3
4^-y - 1 = 4^3
Divide both sides by 4
−y−1=3
Hence, the equation that can be used to find the solution of (1/4)^y+1=64 is
−y−1=3
Answer:
-y-1=3
Step-by-step explanation:

What is the solution set for 9x^2-25 = 0?
Answer:
x=1.666667,−1.666667
Step-by-step explanation:
9x^2−25=0
Step 1: Add 25 to both sides.
9x^2−25+25=0+25
9x^2=25
Step 2: Divide both sides by 9.
9x^2/9=259
x^2=25/9
Step 3: Take square root.
x=±25/9
x=1.666667,−1.666667

Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost?
A. Find the answer.
B. Write a formula for the problem.
Answer:
a. $22.2
b= 13.32/x=3/5
Step-by-step explanation:
13.32/x=3/5
13.32×5=66.6
66.6/3=22.2
x(present cost)=$22.2
Answer:
22.20$
3/5 * cost = 13.32
Step-by-step explanation:
3/5 * cost (total price) = 13.32 (we know that 3/5 of the price is 13.32)
to solve
5/3 to cancel out 3/5 and isolate the cost
5/3 * 13.32 = 22.20

A producer received rupees 10000 when the price of a commodity was rupees 100 per unit. The receipts increased to rupees 15000 when price increased by rupees 20.Calculate the elasticity of supply?
Answer:
Price Elasticity of Supply = 1.25
Step-by-step explanation:
Price Quantity Total Revenue ( P x Q)
100 10000/100 = 100 10000
120 15000/120 = 125 15000
Price Elasticity of supply is change in quantity supplied, due to change in price. Formula : (dQ / dP) x (P / Q)
(125 - 100) / (120 - 100) x (100/100)
= 25/20 = 1.25

Martin is interested in joining a gym and has researched the cost of two gyms close to his house. Gym A has a $50
registration fee and costs $30 per month. Gym B has a $100 registration fee and costs $10 per month. The cost of
joining each gym can be modeled by the expressions below, where m represents the number of months.
• Gym A: 30m + 50
Gym B: 10m + 100
Martin writes the equation 30m + 50 = 10m + 100. What would the solution to the equation tell Martin?
A How many months he could go to the gym for $100
