Answers
Answer:
A
Step-by-step explanation:
We know that [tex]\sqrt{b}=b^{1/2}[/tex].
We also know that [tex](a^b)^c=a^{bc}[/tex].
We can combine these facts to get [tex](\sqrt{b})^2=(b^{1/2})^2=b^{1/2*2}=b^{1}=b[/tex].
So, the answer is [tex]\boxed{A}[/tex] and we're done!
Note: the non-negative part or the equation comes from the fact that you assume the square root of a negative number doesn't exist. You will change this assumption later in the year, or in further years.

A bicycle has a speed of 6 m/s. What is its speed in km/h?
(1 km=1000 m)
(1 h = 3600 s)
Answers
answer:
m/s --- km/h = [tex]\frac{1000}{3600}[/tex]
km/h= [tex]\frac{5}{18}[/tex]
6m/s= [tex]\frac{6*5}{18}[/tex]
6m/s= 1.66 km/h
The speed of the bicycle in km/h is 21.6 km/h.
Given that;
A bicycle has a speed of 6 m/s.
Since we know that;
1 km = 1000 m
And, 1 hour = 3600 s
Hence change the speed of the bicycle in km/h as;
[tex]Speed = 6 m/s[/tex]
It can be equal to;
[tex]Speed = \dfrac{6 \times \dfrac{1}{1000} km }{\dfrac{1}{3600} seconds }[/tex]
[tex]Speed = 21.6 km/s[/tex]
Therefore, the speed of the bicycle in km/h is 21.6 km/h.

Terry’s average driving speed for a 2 and a half hour trip was 58 mph. How far did Terry travel?
Answers
145 miles. lets see how i got this.
so first i took the 2.5 hour trip and the average speed, which was 58 mph (or 93.3 kph), and multiplied them together, because of the rule of d=rt.
sidenote: also if you want to find the speed, use r=d/t. also, for finding the time, use the t=d/r rule.
side-sidenote: i hope this answers your question and helps you in the future.
key: r= rate (mph or kph), d=distance, and t=time.

Jenny & Natasha are working on a problem together: Solve x/3 + 8 = −2. Natasha thinks the first step is to multiply by 3. Jenny explains that this is not the most efficient way to solve. Explain who is correct & justify your reasoning.
Answers
The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method
The given equation is [tex]\frac{x}{3} + 8 = -2[/tex]
Solving the equation using Natasha's method
the fist step is to multiply by 2
x + 24 = - 6
The second step is to combine and add similar terms
x = -24 - 6
x = -30
Second method of solving the equation
The equation the friends are trying to solve is [tex]\frac{x}{3} + 8 = -2[/tex]
The first step is to combine similar terms
[tex]\frac{x}{3}[/tex] = - 8 - 2
The second step is to add similar terms together
[tex]\frac{x}{3}[/tex] = - 10
The third step is to multiply both sides of the equation by 3
x = (-10 x 3)
x = -30

The Mad Hatter is ordering cups from Teacups
Limited, for his tea party. The Tescups, Limited catalog
prices cups according to the number of cups ardered. For
orders of 20 or fewer cups, the price is $1.40 per cup plus
$12 shipping and handling on the order. For orders of
more than 20 cups, the price is $1.10 per cup plus $15
shipping and handling
a) Create a piece wise function to describe the
price of cups
b) How much will it cost the Mad Hatter if he orders
20 cups?
Answers
a) The piecewise function is:
[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
[tex]C(n) = 15 + 1.1n, n > 20[/tex]
b) Applying the piecewise function, it is found that it will cost $40.
A piecewise function is a function that has different definitions based on the input.
Item a:
20 or fewer cups, fixed cost of $12 for shipping plus $1.40 per cup. Thus, the first definition of the function for the cost of n cups is:[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
For more than 20 cups, price of $1.1 per cup plus a shipping and handling fee of $15. Then:[tex]C(n) = 15 + 1.1n, n > 20[/tex]
Then, the piece-wise function is:
[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
[tex]C(n) = 15 + 1.1n, n > 20[/tex]
Item b:
The cost of 20 cups is C(20).It is the first definition, which is valid for [tex]n \leq 20[/tex].Then:
[tex]C(20) = 12 + 1.4(20) = 12 + 28 = 40[/tex]
It will cost $40.

Quinn and Logan solved the equation 8(x-5)=8x+40. Quinn said the answer is x=0, Logan said the answer has infinitely many solutions. Who is right? Explain your answer.
Answers
Answer:
Neither of them are right
Step-by-step explanation:
First, let's actually solve this equation:
8 ( x - 5 ) = 8x + 40
Distribute on the left:
8 ( x - 5 )
( 8 x X ) + ( 8 x ( -5 ) )
8x - 40
8x - 40 = 8x + 40
Add 40 to each side:
8x = 8x + 80
Subtract 8x from both sides:
0 = 80
0 ≠ 80
There are no solutions to the equation

A shipment of sugar fills
4/9 containers. If each container holds 2 2/5
tons of sugar, what is the amount of sugar in the entire shipment?
Write your answer as a mixed number in simplest form.
Answers
Answer:
For this problem, multiply these fractions.
First, make each one an improper fraction: 2 4/5 is the same as 14/5 and 2 3/7 is the same as 17/7.
Now, 14/5 times 17/7 yields 238/35 which reduces to 34/5. This may be expressed also as the mixed fraction 6 4/5.
So, the shipment contains 6 4/5 tons of sugar. (This is also equal to 13,600 pounds of sugar.)
