Katya is traveling by train to visit her relatives in another state. The equation y=60x+20 represents the total distance she is from her home (y) after x hours of traveling on the train
Step-by-step explanation:
Step one:
Given
The expression for Katya's distance away from home is given by the expression
[tex]y=60x+20[/tex]
y represents her total distance away from home
x= represent the time of travel in hours
Step two:
60 represents the rate at which the train is traveling in km per hour
20 represents the initial distance from home
we predict her distance away at a given time
say 4 hours, that is x=4hours
substituting in the expression
y=60x+20
y=60(4)+20
y=240+20
y=260km
Answer:
y=260km

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
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.
The government of a foreign country has recently decided to give a tax rebate to each of its adult citizens. The total amount the government can spend on the program is the equivalent of $5 × 1011. If the adult population of the country is approximately 2.29 × 108, what is a good estimate of the amount of money each person will receive (in dollars)?
Given :
The government of a foreign country has recently decided to give a tax rebate to each of its adult citizens.
The total amount the government can spend on the program is the equivalent of [tex]\$(5 \times 10^{11})[/tex]. If the adult population of the country is approximately [tex]2.29 \times 10^8[/tex].
To Find :
A good estimate of the amount of money each person will receive (in dollars).
Solution :
[tex]\text{Amount per person}= \dfrac{\text{Total amount}}{\text{Number of people}}\\\\A =\dfrac{5\times 10^{11}}{2.29\times 10^8}\\\\A = \$2183.406[/tex]
Hence, this is the required solution.

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

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

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
.
B. How much money he would be spending after m months
C. How much money he would be spending if he joined both gyms
D. How many months until the total spent is the same for both gyms

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.
