Calculate the ranges
of both sets of data.
Enter the correct answers in the boxes.
Hint
Tallahassee: ? °F
Key West: ? °F
Answer:
Tallahassee's Range: 6
Key West's Range: 4
Step-by-step explanation:
To calculate range, you'd subtract the lowest value from the highest value
Tallahassee:
Highest Value: 90
Lowest Value: 84
Range: 90 - 84 = 6
Key West:
Highest Value: 87
Lowest Value: 83
Range: 87 - 83 = 4
Find the volume of the cube whose side length is 6cm
Answer:
volume for cube = length cubed I.e. 6x6×6 = 216
Help me with this please. thanks.
Answer:
Step-by-step explanation:
It's linear.
First of all, let's recreate the table.
The equa ttion is something like
y = a x
Now if x = - 9
and y = - 157 / 3
Then a = -157/ (-9*3)
a = 5.814814814....
y = 5.814814 (-8)
y = - 46.5185185....
y = -139/3 = -46.333333333 the difference is in how this was rounded.
y = 5.814814 * -7 = 40.703703703...
y = -121/3 = -40.333333 Again another rounding problem.
I'm sure if you try the rest of them, they will do the same thing.

a clock cost R179 excluding VAT. if VAT is charged at 14% determined the price of the clock including VAT
Answer: R204.06
Step-by-step explanation:
Cost of clock = R179
Value Added Tax = 14%
The price of the clock will be the addition of the cost of the clock and the value added tax. This will be:
= R179 + (14% × R179)
= R179 + (0.14 × R179)
= R179 + R25.06
= R204.06
Therefore, the price of the clock is R204.06.

y’ =2x - 3y + 1,y(1) = 5; y(1.2)
Applying Euler's method:
Let f(x, y) = 2x - 3y + 1, and consider the following recurrence relations:
[tex]\begin{cases}x_0=1\\x_n=x_{n-1}+h&\text{for }n\ge1\end{cases}[/tex]
[tex]\begin{cases}y_0=5\\y_n=y_{n-1}+f(x_n,y_n)h&\text{for }n\ge1\end{cases}[/tex]
For step size h = 0.1, we can approximate y (1.2) with just 2 steps:
[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.1=3.8[/tex]
[tex]\begin{cases}x_1=1+0.1=1.1\\y_1=3.8\end{cases}\implies y_2=3.8+f(1.1,3.8)\times0.1=\boxed{2.98}[/tex]
For step size h = 0.05, we need 4 steps:
[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.05=4.4[/tex]
[tex]\begin{cases}x_1=1+0.05=1.05\\y_1=4.4\end{cases}\implies y_2=4.4+f(1.05,4.4)\times0.05=3.895[/tex]
[tex]\begin{cases}x_2=1.05+0.05=1.1\\y_2=3.895\end{cases}\implies y_3=3.895+f(1.1,3.895)\times0.05=3.47075[/tex]
[tex]\begin{cases}x_3=1.1+0.05=1.15\\y_3=3.47075\end{cases}\implies y_4=3.47075+f(1.15,3.47075)\times0.05\approx\boxed{3.1151375}[/tex]
(Compare these to the value of y (1.2) found using the exact solution to the differential equation, about 3.22832.)
7. Kgomotso, Themba, Jamal and Alison had
dinner at a restaurant. At the end of the
meal, Kgomotso paid of the total bill.
Themba paid 28% of the bill, Jamal
paid 0,3 of the bill and Alison paid of the bill.
8
What percentage of the bill was the tip?
Answer:
4,99%
Step-by-step explanation:
By Themba you write 28/100 because a percentage means 100 ,you 100 by 28 and then your common fraction answer will be 7/25 in a decimal way it is 0,28 .
Jamal is 0,3 which is 0,3 means 3/10 and Alison 1/8 and the answer for Alison is 0,125 or in a common fraction way it is 125/10.
And then you add all the answers and you get 141/200 .
And then 500-7/25-3/10-0,125 and then you get 499,295, and 499,295÷100 =4,99 which is 4,99%.
I hope this works.
35. Para pintar una casa se mezclaron 5/4 L do pintura blanca y 1/2 L de pintura azul. Al final solo se emplearon 213 L de la mezda,
¿cuántos litros de pintura sobraron?
Answer:
Total paint left over = [tex]\frac{13}{12}L[/tex]
Step-by-step explanation:
Given - To paint a house, 5/4 L of white paint and 1/2 L of blue paint
were mixed. In the end only 2/3 L of the mixture were used.
To find - How many liters of paint were left over ?
Proof -
Given that,
5/4 L of white paint and 1/2 L of blue paint were mixed.
So, total mixture = [tex](\frac{5}{4} + \frac{1}{2})L[/tex]
= [tex]\frac{5 + 2}{4}L[/tex]
= [tex]\frac{7}{4}L[/tex]
⇒Total mixture = [tex]\frac{7}{4}L[/tex]
Now,
Given that ,
In the end only 2/3 L of the mixture were used.
So, total mixture left = [tex](\frac{7}{4} - \frac{2}{3})L[/tex]
= [tex]\frac{21 - 8}{12}L[/tex]
= [tex]\frac{13}{12}L[/tex]
∴ we get
Total paint left over = [tex]\frac{13}{12}L[/tex]

An object start from rest and travelled with a uniform acceleration for 40 seconds reaching a maximum speed of 90 m/s. It maintained this speed for another 10 seconds before breaking and coming to a stop in 12 seconds. (a) Find the acceleration of the object for the first 40 seconds.
Over the first 40 s, the object had an acceleration a such that
90 m/s = a (40 s) → a = (90 m/s) / (40 s) = 2.25 m/s²
Explain the different ways you can name an angle. What
are the different names for this angle?
Answer:
You have an right angle which is like an L and is 90 degrees. A acute angle and it just like if you was to close a L just a little bit you would get an acute angle which is 30 degrees. Last you have the the obtuse angle it´s like is you pulled the top of L and pulled it back a little bit you would get that. I mean those are the basic angles.
