A bookstore sells art books for $25 each. There are 16 books at the store. Identify the graph that represents this situation.
Step-by-step explanation:
I believe its the one on the top of the second picture because if there is only 16 books they can sell then thats the only one that makes sence hope this helped
Graph third represents the situation if a bookstore sells art books for $25 each. There are 16 books at the store option (C) is correct.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A bookstore sells art books for $25 each. There are 16 books at the store.
Let x be the total number of books sold and y be the total amount earned:
The linear equation can be framed as follows:
y = 25x
After plotting the graph of the above linear equation we will get a graph exactly the same as mentioned in the graph third.
Thus, the graph third represents the situation if a bookstore sells art books for $25 each. There are 16 books at the store option (C) is correct.

35. The distance between two cities on a map is 3.5 centimeters. The map uses a scale
in which 1 centimeter represents 20 kilometers. What is the actual distance
between these two cities in kilometers?
Answer:
The distance between two cities is 70 km.
Step-by-step explanation:
Given that,
The distance between two cities on a map is 3.5 centimeters.
It is also mentioned that the map uses a scale in which 1 centimeter represents 20 kilometers.
We need to find the actual distance between these two cities in kilometers.
1 cm = 20 km
3.5 cm = (3.5 × 20) km
= 70 km
Hence, the distance between two cities is 70 km.
A radius of a circle is perpendicular to a chord if and only if it
A. is equal in length to that chord
B. parallels that chord
C. bisects that chord
D. intersects the chord directly on the circumference
Answer:
C. bisects that chord
Step-by-step explanation:
The radius of a circle is perpendicular to a chord if and only if it bisects the chord. Therefore, the option b is correct.
Radius of the circle:In the case when the diameter or the radius should be perpendicular with respect to the chord so it should be bisected the chord also its arc.
At the time when the two chords should be congruent so their corresponding arc should also be congruent.
Therefore, the option b is correct.

1. The scale of a map is 1:1000. What are the actual dimensions of a
rectangle which appears as 4 cm by 3 cm on the map? What is the area
on the map in cm2 ?What is the actual area in m2?
Answer:
Step-by-step explanation:
4 cm × 1000 = 4000 cm = 40 meters
3 cm × 1000 = 3000 cm = 30 meters
A 4 cm by 3 cm section on the map represents 40 m by 30 m.
area = 40 m × 30 m = 1200 m²
Name the steps of solving 5x+4=40
Answer:
Step-by-step explanation:
Simplifying
5x + -4 = 40
Reorder the terms:
-4 + 5x = 40
Solving
-4 + 5x = 40
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 5x = 40 + 4
Combine like terms: -4 + 4 = 0
0 + 5x = 40 + 4
5x = 40 + 4
Combine like terms: 40 + 4 = 44
5x = 44
Divide each side by '5'.
x = 8.8
Simplifying
x = 8.8

HELP PLEASEEE!!!!!!! The population in Smalltown in 2010 was 56,382 people and is growing exponentially at a rate of 1.2 percent. Which of the following equations defines the population t years after 2010?
a. P= 56,382(1+0.12)^t
b. P= 56,382(1+0.012)^t
c. P= 56,382e^0.012t
d. P= 56382e^1.2t
Answer:
b. P = 56,382(1+0.012)^t
The equation that defines the population in Smalltown t years after 2010 is [tex]P = 56,382(1 + 0.012)^t[/tex]
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The population P after 2010 is an exponential growth function of the form:
[tex]P = P_{0} (1 + r)^t[/tex]
where P₀ is the initial population,
r is the annual growth rate as a decimal, and
t is the time in years.
Byu given information P₀ = 56,382,
r = 0.012, and
t is the number of years after 2010.
The equation that defines the population in Smalltown t years after 2010 is:
[tex]P = 56,382(1 + 0.012)^t[/tex]
Hence, equation that defines the population in Smalltown t years after 2010 is [tex]P = 56,382(1 + 0.012)^t[/tex]

Given log34≈1.262 and log37≈1.771, what is the value of log3(167)?
Enter your answer in the box.
Answer:
0.753
Step-by-step explanation:
I just took the test lol
The value of log₃(⁷/₁₆) when log₃4 = 1.262 and log₃7 = 1.771 is;
log₃(⁷/₁₆) = -0.753
We are given;
log₃4 = 1.262
log₃7 = 1.771
We want to find log₃(⁷/₁₆)
Now, from properties of logarithm too, we have;
logₐ(x/y) = logₐx - logₐy
Thus; log₃(⁷/₁₆) = log₃7 - log₃16
Also, we know that; logₐx² = 2logₐx
Thus; log₃16 = log₃4²
log₃16 = 2log₃4
Thus; log₃(⁷/₁₆) = log₃7 - 2log₃4
Plugging in the relevant values gives;
1.771 - 2(1.262) = -0.753

After 2 years, how much is the phone worth?
Write an equation for the value of the phone, , years after it is released.
Answer:
It will be worth $128.
Step-by-step explanation:
After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.

Justin plans to spend $35 on sports cards. Regular cards cost $4.50 per pack and foil cards cost $6.00 per pack Which inequality shows the relationship between the number of packs of regular cards (r) and the number of packs of foll cards (f) Justin can afford to buy?
Answer:Justin plans to spend $20 on sports cards. Regular cards cost $3.50 per pack and foil cards cost $4.50 per pack
number of packs of regular cards =r and the number of packs of foll cards = f
Cost of Regular card = 3.50
Cost of 'r' packs of regular card = 3.50r
Cost of Foil card = 4.50
Cost of 'f' packs of Foil card = 4.50f
Justin plans to spend $20 on sports cards so the sum of cost of regular and Foil cards should be less than or equal to 20
The inequality becomes
3.50r + 4.50f <= 20
