Answer:
I think 21/12
Step-by-step explanation:
hope it works out,!!
Answer:
Here is the answer 21/12
Step-by-step explanation:
to break 21/12 into a fraction we need to subtract, add a whole.
21-12 is 9 1 9/12
now we need to find a gcf for only 9/12 but divide
this is because the gcf of 4/5 is only 1 so we can’t use it
the gcf for 9/12 is 3
9/12 divided by 3 is 3/4
to know what’s greater I use the butterfly trick Which is sideways multiplying
3. 4
- -
4 5
3 x 5 is 15
4 times 4 is 16
below the 16 should be 4/5
and if you look all the way at the top, it started as 21/12
so it is 21/12

Joshua uses his thermometer and finds the boiling point of ethyl alcohol to be 75 degrees Celsius. He looks in a reference book and finds that the actual boiling point of ethyl alcohol is 80 degrees Celsius. What is his percent error?
Answer:
6.25%
Step-by-step explanation:
Percent error is calculated by taking the difference of measured value and correct value divided by correct value and multiplied by 100%.
Mathematically,
Percent error = (correct value - measured value)/correct value * 100%
_________________________________________________
in the problem given
measured value = 75 degrees Celsius
correct value = 80 degrees Celsius ( as given in reference book)
thus,
Percent error = (80 - 75)/80 * 100%
Percent error = (5/80 )* 100% = 6.25%
Percent error calculated by him is 6.25%.
We will see that the percent error in Joshua's measure is:
Pe = 6.25%
How to get the percent error in a measure?
The percent error for a measure is computed as:
[tex]P_E = (\frac{A - M}{A})*100 \%[/tex]
Where A is the accepted value and M is the measured value.
Here we have:
A = 80°C
M = 70°C
Replacing that we get:
[tex]P_E = (\frac{80 \°C - 75 \°C}{80 \°C})*100 \% = 6.25 \%[/tex]
So we can conclude that the percent error is 6.25%

Step-by-step explanation:
75%=0.75
300/0.75 = 400
Answer:
400
Step-by-step explanation:
75/100 of x = 300

Cross multiplying
75x = 30000
Dividing the both by 75
x = 400
Please help! For the function f(x) = 2x^6 + 3x^4 - 4x^3 + (1/x) - sin(2x) find the first four derivatives.
Answer:
See the explanation
Step-by-step explanation:
We know that
f(x) = 2x⁶ + 3x⁴ - 4x³ + (1/x) - sin2x
Lets calculate the derivatives:
f'(x) = 6(2x⁵) + 4(3x³) - 3(4x²) -( 1/x²) - 2(cos2x)
f'(x) = 12x⁵ + 12x³ - 12x² - (1/x²) - 2cos2x
Similarly:
f''(x) = 60x⁴ + 36x² - 24x + (2/x³) + 4sin2x
f'''(x) = 240x³ + 72x - 24 - (6/x⁴) + 8cos2x
Rearrange:
f'''(x) - 240x³ +72x - (6/x⁴) + 8cos2x - 24
f''''(x) = 720x² + 72 + (24/x⁵) - 16sin2x
Rearrange:
f''''(x) = 720x² + (24/x⁵) - 16sin2x +72

Need $13.75 to complete template for white fabric
Step-by-step explanation:
Template requires 18 square feet of white, 20 square feet of light blue and 21 square feet of dark blue.
She has more than enough for both shades of blue fabric.
She needs 5.85 square feet more of white fabric
Since it is $2.35 per square feet of white fabric, 2.35 * 5.85 = $13.75.
It will cost her $13.75 for more white fabric

Answer:
i) x= -0.25, x=1.25
ii)x=1.5, x= -0.5 (notice the negative signs)
Step-by-step explanation:
So, to simply solve this(or estimate), notice what the equations say at the end of them!
0 and 2, and also notice the equations are exactly the same as the graph's.
This means, by substitution, we are look for the x-values at y=0, and at y=2
(because they are exactly the same, in those instances, we can just replace the equation with the value of 0, or 2 because they are equal)
Then all we have to do is imagine the lines of y=0(x-axis) and y=2, and find where the parabola intersects those lines.
And so, just find where they intersect, and you have got it!

please help me find the volume for this triangular prism
Answer:
140 yd³
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = Ah ( A is the area of the triangular face and h is the depth )
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
= 0.5 × 5 × 8 = 20 yd² , thus
V = 20 × 7 = 140 yd³
Suppose that a population begins at a size of 100 and grows continuously at a rate of 200% per year. Give the formula for calculating the size of that population after t years. Question 3 options: A) A = 100 + 2et B) A = 100 + te2 C) A = 100e2t D) A = 100 + e2t
Answer:
100 (+1) x 2^t = 100 (+2et) as we plus and we multiply before squaring the years.
Step-by-step explanation:
You cna now work this out as +1 represents the 100% + 200% sum.
Answer:
C) [tex] A = 100e^{2t} [/tex]

If Larry gets 5% of 80 questions wrong, how many did he get correct? Provide an explanation :)
A. 8
B. 70
C. 4
D. 76
Answer:
The answer is D.
Step-by-step explanation:
Given that Larry wrong 5% of the questions and he correct the remaining 95%. So in order to find how many questions he correct, first, you have to convert the percentage to decimal by dividing it by 100 :
[tex]95\% = \frac{95}{100} = 0.95[/tex]
Next, you have to multiply by the total number of questions :
[tex]0.95 \times 80 = 76 \: questions[/tex]
