Which ratio is equivalent to the rate
8 meters
1 second
?
Answers
The ratio as a unit rate is 0.8 meters per second.
What is a Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
The given statement is "8 meters in 10 seconds".
It can be written as:
= 8/10 meters per second
= 0.8 meters per second
Thus, the ratio as a unit rate is 0.8 meters per second.

Lynne walks dogs every day to earn money. The fees she charges per month are 1 dog,$40;2 dogs,$37.25 each;3 dogs,$34.50 each;4 dogs,$31.75 each. A pet store wants her to walk 8 dogs if the pattern continues, how much will Lynne charge to walk each of the 8 dogs.
Answers
Answer:
The answer is $20.75
A dog: 40$
2: $37.25
3: $34.50
4: $31.75
5: $29
6: $26.25
7: $23.50
8: $ 20.75
Step-by-step explanation:
Minus $2.75 is the pattern
Answer:
$ 59.25
Step-by-step explanation:
The given rates form an AP (Arithmetic Progression).
Let the cost of walking 1 dog be taken as the first term
and,
cost of walking 2 dogs as second term,
we notice that the price per dog is decreasing by 2.75 $ each time the number of dogs is increasing by 1.
So, it's safe to say that
In the AP:
First term is $ 40
Common difference is $ 2.75
Finding the charge to walk each of the eight dogs is like finding the 8th term of the given Series.
Formula for n-th term of a depreciating AP in terms of common difference(d) and first term(a):
[tex] \boxed{ \mathsf{a _{n} = a - (n - 1)d}}[/tex]
[tex] \implies \mathsf{a _{8} = 40 - (8 - 1) \times 2.75}[/tex]
[tex] \implies \mathsf{a _{8} = 40 - 7 \times 2.75}[/tex]
[tex] \implies \mathsf{a _{8} = 40 - 19.25}[/tex]
[tex] \implies \mathsf{a _{8} = \underline{20.75}}[/tex]
Answer:Hence, the charge to walk each of the eight dogs is $ 20.75
8. Beth doesn’t begin receiving commission until she reaches $50,000 in sales. After that, her commission rate is 12%. If she ends up selling cars totaling $115,000, how much money would she make in commission?
A.$13,800
B.$6,000
C.$7,800
D.$8,400
Answers
Step-by-step explanation:
she is the only sales agent selling cars after totaling them ... :-)
she makes 12% commission on the amount of sales beyond $50,000.
so, total sales was $115,000.
the base for her commission is then
115,000 - 50,000 = $65,000
she gets 12% of these $65,000.
100% = $65,000
1% = 100%/100 = 65,000/100 = $650.
12% = 1%×12 = 650 × 12 = $7,800
so, C is the right answer.

Answer:
x = 1y = -7Step-by-step explanation:
The coefficients of x and y do not have any "nice" relations, so doing this by elimination is just "brute force" with no particular subtlety.
After multiplying by appropriate numbers, you want the coefficient of one of the variables in one equation to be the opposite of the coefficient of the same variable in the other equation. Here, we can get that by multiplying the first equation by 7 and the second equation by 2.
7(2x +3y = -19) ⇒ 14x +21y = -133
2(-7x +2y = -21) ⇒ -14x +4y = -42
Adding these equations with opposite x-coefficients eliminates the x-terms. (That is how the "elimination" method gets its name.)
(14x +21y) +(-14x +4y) = (-133) +(-42)
25y = -175 . . . . . . . . simplify
y = -7 . . . . . . . . . . . divide by 25
Substituting this value into the first equation gives ...
2x +3(-7) = -19
2x = 2 . . . . . . . . . add 21
x = 1 . . . . . . . . . divide by 2
The solution is x = 1, y = -7.
_____
Additional comment
The multipliers used in this process are essentially the coefficients of one of the variables, with one of them negated. Here, we chose the x-coefficients, because negating one of them gives two positive multipliers. We judge it easier to do the arithmetic using positive numbers.
Had we chosen to use the y-coefficients (3 and 2) for our multipliers, we would probably multiply the first equation by 2, and the second equation by -3. That way, the remaining x-coefficient would be positive.
Planning ahead is helpful, but not essential. It can help to avoid errors and make the work easier to do.

The simplification of the given expression gives the value 9.
What is simplification?Simplification is defined as a process in mathematics to operate and interpret an expression to make the expression simpler.
This can be done using various results or the basic operations of numbers.
Given expression is 3⁻⁶ × (3⁴ / 3⁰)².
We have to use product rule and quotient rule of exponents to simplify this.
We know that,
xᵃ × xᵇ = xᵃ⁺ᵇ
xᵃ / xᵇ = xᵃ⁻ᵇ
Also, (xᵃ)ᵇ = xᵃᵇ
3⁴ / 3⁰ = 3⁴⁻⁰ = 3⁴
Substituting,
3⁻⁶ × (3⁴ / 3⁰)² = 3⁻⁶ × (3⁴)²
= 3⁻⁶ × 3⁸
= 3⁻⁶⁺⁸
= 3²
= 9

what does i^739 equal? explain how you found your answer.
Answers
========================================================
Explanation:
i = sqrt(-1)
Lets list out the first few powers of i
i^0 = 1i^1 = ii^2 = -1i^3 = i*i^2 = i*(-1) = -ii^4 = (i^2)^2 = (-1)^2 = 1By the time we reach the fourth power, we repeat the cycle over again (since i^0 is also equal to 1). The cycle is of length 4, which means we'll divide the exponent over 4 to find the remainder. Ignore the quotient. That remainder will determine if we go for i^0, i^1, i^2 or i^3.
For example, i^5 = i^1 because 5/4 leads to a remainder 1.
Another example: i^6 = i^2 since 6/4 = 1 remainder 2
Again, we only care about the remainder to find out which bin we land on.

Turning to the question your teacher gave you, we have,

if i^a = i^b, then a-b is a multiple of 4Recall that the divisibility by 4 trick involves looking at the last two digits of the number. So i^739 is identical to i^39.Find the area of the shape. Either enter an exact answer in terms of π or use 3.14, point, for π and enter your answer as a decimal.

The true statement is (a) it is stretched horizontally by a factor of 2 and translated up, 3 units.
The function is given as:
[tex]y = \log(x)[/tex]
Start by stretching the graph of [tex]y = \log(x)[/tex], horizontally by a factor of 2.
So, we have:
[tex]y = \log(2 \times x)[/tex]
[tex]y = \log(2x)[/tex]
Next, shift the function up by 3 units.
So, we have:
