What is the equation of the graph?
Evaluate 64 = (15 – 7) x 2 - 9.
Answer:
No solutions.
Step-by-step explanation:
We need to use PEMDAS to solve this problem, and as the first letter in PEMDAS stands for (parentheses) we should subtract 7 from 15 to get 8.
Secondly, we would multiply 2 by 8 to get 16.
Finally, we subtract 9 from 16 to get 7.
64 ≠ 7, so the answer would be no solutions.

Water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. Which would not be a proportional you could use to solve for the gallons of water going over the waterfall in 2 2/3 hours? *more then one answer*
Answer:
look below
Step-by-step explanation
First, we need to convert 2 2/3 hours to minutes. This would be:
= 2 2/3 × 60 minutes
= 8/3 × 60 minutes
= 160 minutes
Since water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. The the gallons of water going over the waterfall in 2 2/3 hours would be:
= (162 1/2 × 2 2/3hours) / 15 minutes
= (162 1/2 × 160) / 15
= 1733 1/3 gallon

A shelf at a bookstore displays 30 books. Of these 30 books, 10 of the books are nonfiction books. The store owner adds 4 new fiction books to the shelf and wants the ratio of fiction books to nonfiction books to remain the same. What is the total number of nonfiction books that the store should display, after the new fiction books are added?
Answer:
2 he needs to add 2 to keep the ratio the same, the total would be 12
Step-by-step explanation:
before he adds the book the ratio is 2:1 (fiction to non-fiction) and he add 4 to the fiction so he needs to add 2 non-fiction books because this ration means fiction/2 = non-fiction so 4/2 = 2

Answer:
1. g. $0.10 per square inch
2. b. $0.08 per square inch
3. f. $10
4. m. $8
5. h. 79 in²
6. j. 113 in²
Step-by-step explanation:
1. A = πr²
r = diameter ÷ 2 = 10 ÷ 2 = 5
A = π(5)² = 25π in² ≈ 78.53981
$8.00/25π = $0.10 per square inch
2. A = πr²
r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113.0973355
$10.00/36π = 0.088419 = $0.09 per square inch
3. information/answer was provided
4. information/answer was provided
5. A = πr²
r = diameter ÷ 2 = 10 ÷ 2 = 5
A = π(5)² = 25π in² ≈ 79 in²
6. A = πr²
r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113 in²
Simlify the expression 4^3 +(3 - 2).
Answer:
The answer is 65
Step-by-step explanation:
3-2 = 1
4^3 = 64
64+1 = 65
Hope this helps.
Answer:
[tex]65[/tex]
Step-by-step explanation:
Firstly, you have to Simplify what's inside the parentheses.
and that is 3-2 = 1.
[tex] {4}^{3} + 1[/tex]
Secondly, you have to Simplify 4³ to 64. 4 to the power of 3 is 64.
[tex]64 + 1[/tex]
And lastly, you have to simplify 64 + 1. which is.
[tex]65[/tex]
Therefor, the answer is, 65.

please guys or girls I really need help for this question im failing math
Answer:
Yes it is proportional (Equation: y=3.5x)
Step-by-step explanation:
Notice that there is a constant change in y and a constant change in x. But by how much? Given the last point (13,45.5) we can see that 13-12=1 and 45.5-42=3.5 so that means as x increases by 1, y always increases by 3.5, making the relationship proportional. You can also write the equation y=3.5x to show this

which equation represents the inverse of f(x)=(x+3)^2+5 for x ≤-3
Answer:
f(x)=(x+3)^2+5
let f(x)=y
y=(x+3)^2+5
interchanging role of x and y
x=(y+3)²+5
x-5=(y+3)²
√(x-3)-3=y
y=√(x-3)-3
:.inverse of f(x)=(x+3)^2+5 is f-¹(x)=√(x-3)-3

Determine the value for b assuming that the two horizontal lines displayed are parallel.
Answer:
29
Step-by-step explanation:
The value of b by assuming that the two lines are parallel will be equal to 29°.
What is an angle?When two lines converge at a point, they produce an angle. The word "angle" refers to the length of the "gap" between these two rays. The symbol is used to denote it.
Radians, a unit of roundness or rotation, and degrees are the 2 most common units used to measure angles. In daily life, angles are present.
As per the given information provided by the given figure,
The angle is corresponding in nature,
So, the equation will be,
3b + 5 = 92
3b = 92 - 5
3b = 87
b = 87/3
b = 29°.
Therefore, the angle b is 29°.
