Answer: 6.4 hours
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each case:
Happy paws: the cost is equal to the fixed charge (19) plus the product of the charge per hour (3.50) and the number of hours (h).
Happy Paws Cost = 19+3.50h
Woof Watchers: the cost is equal to the fixed charge (11) plus the product of the charge per hour (4.75) and the number of hours (h).
Woof Watcher Cost = 11+ 4.75h
Since both costs must be equal:
Happy Paws Cost =Woof Watcher Cost
So:
19+3.50h = 11+ 4.75h
Solving for h:
19-11 = 4.75h-3.50h
8 = 1.25h
8/1.25 =h
h = 6.4 hours
Please write a Complete answer.
Answer:1. 8.6 2. 9.4 3.8.5
Step-by-step explanation:
Answer: The first puppy would weigh: 8.6 ounces
The second puppy would weigh: 9.4 ounces
The third puppy would weigh: 8.5 ounces
Step-by-step explanation: The puppies weights were 6.5, 7.3, and 6.4 respectively. The question says each puppy gained 2.1 ounces
So just add 2.1 to each of the puppies weights:
6.5+2.1=8.6
7.3+2.1=9.4
6.4+2.1+8.5

1. Mr. Paul pays the parking bill before tax at a cost of $33.20. The parking tax rate is 2%. Mr. Paul decides to leave a 5% tip for the parking guard based on the pre-tax amount. How much will the total bill be?
2. Mr. Smith paid $36.36 for a carpet. This amount includes a tax of 10%. What was the cost of the carpet before tax?
Answer:
for the first question the total bill is $35.524
for the 2nd question the answer is $36.36 = 110%.
$36.36 ÷ 1.1 = $33.054
(the five and the four are recurring)
(I divided by 1.1 because 1.1 is the same as 110%)

Answer:
4) 8^14
7) h^7
10) 29^8 over 10^8
Step-by-step explanation:
If the numbers have the same base, just add their exponents together. So 10 plus 4 is 14.
Same thing for the second problem, since you have the same base, just add the exponents together. 6 plus 1 is 7
The bases are the same so just add the exponents, 7 plus one is 8.
(-2.9)^8
Convert it into a fraction: -(29/10)^8
Raise the fraction to the power (8) and the numerator and denominator to that power: 29^8/10^8

The volume of a stack of identical circular drink coasters, each 1 centimeter thick, can be found using the function V(r)=8pi r^2 where r is the radius of a coaster. What does the constant 8 in the function represent?
Answer:
The constant 8 represents the height of the stack and hence the number of coasters. (It represents the number of coasters.)
Step-by-step explanation:
The formula for finding the volume of a cylinder is
V = πr²h
If you we take π =3.14 and h = 1 cm, as given in the question, then we can rewrite the formula for the volume of one coaster as
V = 3.14 * r²
But the formula in this question is
V(r) = 8*3.14 * r² so this means that there are 8 coasters here hence the formula for one coaster being multiplied by 8.

17. The amount of time, t, in seconds, it takes an object
to fall a distance
Answer:
C) 3.9 sec
Step-by-step explanation:
You have given the time formula; t = square root of d divided by square root of 4.9.
Well d = 75m
square root of 75 = 8.66
square root of 4.9 = 2.2
8.66 / 2.2 = 3.9363...
t = 3.9 sec

The average weight of 7 potted plants is 23 pounds. An 8th potted plant is added to the pallet,
and the average weight increases to 25 pounds. What was the weight, in pounds, of the 8th
plant?
Answer:
The weight of the 8th plant is 39lb
Step-by-step explanation:
Given:
Average Weight of 7 plants = 23lb
Average Weight of 8 plants = 25lb
Required:
Weight of the 8th plant
To solve this, the total weight of the initial 7 plants need to be calculated;
[tex]Average = \frac{Sum-of-weights}{Number-of-Plants}[/tex]
Substitute 23 for Average and 7 for Number of plants
[tex]23 = \frac{Sum-of-weights}{7}[/tex]
Multiply both sides by 7
[tex]7 * 23 = \frac{Sum-of-weights}{7} * 7[/tex]
[tex]161 = Sum-of-weights[/tex]
Hence, the 7 plants weigh 161
Represent the weight of the 8th plant with E
When the 8th plant is added;
The sum of the weight becomes 161 + E
And the number of plants becomes 8
The average is calculated as thus
[tex]Average = \frac{Sum-of-weights}{Number-of-Plants}[/tex]
[tex]25 = \frac{161 + E}{8}[/tex]
Multiply both sides by 8
[tex]8 * 25 = \frac{161 + E}{8} * 8[/tex]
[tex]200 = 161 + E[/tex]
Subtract 161 from both sides
[tex]200 -161 = 161 - 161 + E[/tex]
[tex]39 = E[/tex]
Reorder
[tex]E = 39[/tex]
Hence, the weight of the 8th plant is 39lb

Step-by-step explanation:
Which of the given line segments is congruent to AB?
Answer:
VW
Solution:
VW is congruent to AB, because they have the same length.
The line segment VW is congruent to AB.
What are congruent line segments?A pair of line segments are said to be congruent when the lengths of both the line segments are equal.
How do we solve the given question?To solve the given question, we compare each line segment with AB to find its congruent pair.
PQ: PQ > AB, so its not congruent to AB.RS: RS < AB, so its not congruent to AB.TU: TU < AB, so its not congruent to AB.VW: VW = AB, so its congruent to AB.∴ We can say that VW is the line segment congruent to AB.

Answer:
The electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. For example, the electron configuration of sodium is 1s22s22p63s1.

Which property of polynomial addition says that the sum of two polynomials
is always a polynomial?
O A. Commutative
O B. Multiplication property of equality
C. Distributive
D. Closure
SUBMI
Answer:
The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.
Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.
In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.

For the function f(x) = 3(x − 1)2 + 2, identify the vertex, domain, and range. The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2. The vertex is (1, 2), the domain is all real numbers, and the range is y ≤ 2. The vertex is (−1, 2), the domain is all real numbers, and the range is y ≥ 2. The vertex is (−1, 2), the domain is all real numbers, and the range is y ≤ 2.
Answer:
The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2
Step-by-step explanation:
The functions given to us is:
f(x) = 3(x - 1)² + 2
Domain:
As there is no limitation of x, all value of x are possible. So
Domain = All real numbers
Range:
For all values of x, the minimum value of y is 2 calculated at x = 1. The rest of the values are greater than 2. So,
Range = y ≥ 2
Vertex:
Simplifying the function:
f(x) = 3(x² + 1² - 2(x)(1)) + 2
f(x) = 3(x² - 2x + 1) +2
f(x) = 3x² - 6x + 3 + 2
f(x) = 3x² - 6x + 5 (ax² + bx + c)
where a = 3, b = -6, c = 5
x-coordinate of Vertex is given as:
Vertex(x) = -b/2a = 6/2(3)
Vertex(x) = 1
Substitute x=1 in the function, we get
Vertex(y) = 2
So Vertex is at (1,2)
Answer: A. The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2.

The given Equation y=-1/3x+7 represents the table on the left side because when x = 0 y = 7. The equation for the table on the left is y=1/3x+5 because when x = 0 y = 5 and when y goes up 1 x goes up 3. The solution is (3, 6) because the only point in both tables is (3, 6)
Answer:
y = (1/3)x + 5
Step-by-step explanation:
y = (-1/3)x + 7 matches the second table (the table on the right side). Note that if x = 0, y = 7, and that this point, (0, 7) is found in the second table. The other table shows that when x = 0, y = 5; this point, (0, 5), is the y-intercept of the function whose values are in the first table. To finish this work, we need onlyl find the slope of the function represented by the first table:
y = mx + b becomes 6 = m(3) + 5, or 1 = 3m, or m = 1/3.
The the function represented by the first table is y = (1/3)x + 5.
