Simone is a competative gymnatist and practices 5 times a week to prepare for the Olympics. In one month, she practices for 1 2/3 and hours, 5 days a week. The next week, she practied 3 3/4 an hours for 5 days a week. The third week she practiced 5 5/6 and hours for 5 days a week.

Each week Simone increased her practice time per day. How much did she increase it from the first week to the third week?

Answer- 5g+ 69.50= 85  ; 3.1 (3)

An inequality is an equation with letters and number that sum to ONE whole.

In this case we have a flat cost, which is standalone and 5 dollars per gigabyte which is not standalone. Let G stand for each gigabyte.

This means our equation is 5g(five dollars times each gigabyte used) +69.50 that is gives. He has to keep his entire month under 85 dollars, which means our equation must equal 85. Now our equation will look like this.

Inequality- 5g+ 69.50= 85.

In order to solve how many gigabytes will be used we solve our equation backwards. We subtract 69.50 from 85,because we know that must has already been spent. This gives us 15.50. This means we will have to divided 15.50 into five dollars to see how many gigabytes are spent. 15.50 divided into five is 3.1 gigabytes.

This means Alexander will have to use 3.1 (or 3 if you have to round) gigabytes in order to spend 85 dollars or less per month.

The answers is: 33

33 is the integer that represents her location relative to the surface after 7 seconds.

And 33 feet far the diver have to go to return to the surface.

Step-by-step explanation:

Given:

A scuba diver is 15.5 feet below the surface of the water.

The diver continues to swim downward at a rate of 2.5 feet per second.

Now, to find the integer represents her location relative to the surface after 7 seconds.

And to find how far does the diver have to go to return to the surface.

So, to get the integer represents her location relative to the surface after 7 seconds.

Initial depth = 15.5 feet.

Distance traveled down = 7 × 2.5 = 17.5 feet.

Final depth of water surface = Initial depth + Distance traveled down.

Final depth of water surface = 15.5 feet + 17.5 feet.

Final depth of water surface = 33 feet.

Thus, 33 is the integer represents her location relative to the surface after 7 seconds.

Now, to get how far does the diver have to go to return to the surface:

As, the diver goes to 33 feet down to the surface.

Thus, the diver to return she have to go through the same distance.

So, to return to the surface she need to go to 33 feet far.

Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.

And 33 feet far the diver have to go to return to the surface.

Step-by-step explanation:

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answer: Vaughn collected 72 pieces of litter.

Step-by-step explanation: The equation is correct. You get that by going backwards through the information in the story.

Vaughn's number is x.

Piper is 1/4 x

Sara is Piper +12 So (1/4 x)+12

Dom is Sara -15. So (1/4 x) -3

Add all Piper, Sara & Dom on one side of the equation.

The other side is the Vaughn's amount minus 9 because it says he picked up 9 more than the others combined. So x-9 equals the amount of the other three combined.

The three 1/4 x add to 3/4 x

Skipping to the solution:

x - 3/4 = 12 -3 +9

1/4 x = 18 Multiply both sides by 4

x = 72

1/4 x is 18, Piper's number.

Use that to calculate the Sara and Dominique.

Answer:

Her new hourly rate is $7.15. She would need to work 35 hours  in the next two weeks to make the same amount she made in the first two weeks

Step-by-step explanation:

6.50+.65=7.15 which is the new hourly rate

19+19.50 to find how many hours in total which is 38.5 hours

you multiply the rate of 6.50 by 38.5 and you get $250.25 in 2 weeks for the old rate.

I just multiplied until I found the amount of hours to make 250.25 with the new rate.

7.15x35=250.25

Answer:

New hourly rate: $7.15

Total number of hours: 35

Step-by-step explanation:

Given Nadia's hourly rate of $6.50:

For the first week of the month, she babysits for 19.50 hours:

$6.50 per hour × 19.50 hours = $126.75  (Week 1)

For the second week of the month, she babysits for 19 hours:

$6.50 per hour × 19 hours = $123.50 (Week 2).

For those two weeks, she worked for a total of 38.50 hours, and earned $250.25.

Nadia increased her hourly rate by $0.65, which means that her new hourly rate will be: $6.50 + $0.65 = $7.15 per hour.

Since we need to determine how many hours she needs to work for in the next two weeks to make the same amount as she did in the first two weeks, we could divide her weekly earnings by her new hourly rate for babysitting:

Divide Nadia's earnings for week 1 by $7.15:

$126.75 ÷ $7.15 = 17.72 hours

Divide Nadia's earnings for week 2 by $7.15:

$123.50 ÷ $7.15 = 17.27 hours

Week 3 + Week 4 hours = 17.72 + 17.27  = 34.99 or 35 hours

If you multiply her total working hours for weeks 3 and 4 by her new hourly rate:

35 hours × $7.15 per hour =  $250.25  (This matches her total earnings for Week 1 and 2).

Therefore, Nadia's new hourly rate is $7.15. She would need to work for 35 hours in the next two weeks to make the same amount she made in the first two weeks.

Answer: It is greater than 2

Step-by-step explanation:

Answer:

greater than 2

Step-by-step explanation:

Answer:

no bro, sorry. even though I needed to I don't have it

I believe and think the answer is number 2

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

to get the slope of any straight line, we simply need two points off of it, let's use those two in the picture below.

\((\stackrel{x_1}{6}~,~\stackrel{y_1}{194})\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{178}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{178}-\stackrel{y1}{194}}}{\underset{\textit{\large run}} {\underset{x_2}{8}-\underset{x_1}{6}}} \implies \cfrac{ \stackrel{Lbs}{-16 }}{ \underset{Weeks}{2} } \implies \cfrac{\stackrel{Lbs}{-8}}{\underset{Weeks}{1}}\implies {\Large \begin{array}{llll} -8~\frac{Lbs}{Week} \end{array}}\)

Answer:

y= -5x+3/5

Step-by-step explanation:

start by finding the y value, because it is on the y axis it's -5. next find the rise so in this case it is 3 then find the run it is 5, put the rise and run in fraction form 3/5 (remeber rise over run) and you get the awnser y= -5x+3/5

well, the total is "x", which oddly enough is the 100%.

now, we know that 18.9% of "x" is 43100, what the dickens is "x"?

\(\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 43100& 18.9 \end{array} \implies \cfrac{x}{43100}~~=~~\cfrac{100}{18.9} \\\\\\ 18.9x=4310000\implies x=\cfrac{4310000}{18.9}\implies x\approx 228042\)

Answer:

The answer will be 20.

Step-by-step explanation:

If both lighthouses A and B sound their foghorns at the same time, it will be after 20 hours before both foghorns sound at the same time again.

Since lighthouse A sounds it's foghorn every 4 hours, and lighthouse B sounds it's foghorn every 10 hours.

To determine the next time when both foghorns sound at the same time;

We need then need to determine the lowest common multiple (LCM) of 4 and 10.

The lowest common multiple of 4 and 10 is going to be 20.

Therefore they will sound at the same time after 20 hours.
