Answer:
4 hours
Explanation:
[tex]\sf time = \dfrac{distance}{speed}[/tex]
Here the units are same for both, so no need of conversion.
Solve:
time taken = distance/speed
time taken = 320/80
time taken = 4 hours
Answer:
4 hours
Step-by-step explanation:
[tex]\text{Speed} =\frac{\text{distance} }{\text{time} }[/tex]
Then
[tex]\text{time} =\frac{\text{distance} }{\text{speed} }[/tex]
Then
[tex]\text{time} =\frac{\text{320} }{\text{80} } =4[/tex]

3 135
5 225
6 270
1. Find the constant of proportionality.
2. Use the constant of proportionality to write a unit rate for the data in the table.
3. Write an equation to represent the relationship between time, t, and distance, d.
Can you please do step by step showing us how you got the answers?
Answer:
1. Time (hours): 1 Distance (miles): 45
2. 1;45
2;90
3;135
4;180
5;225
6;270
3. (c= constant of proportionality)
c= [tex]\frac{distance}{time}[/tex]
c=[tex]\frac{90 miles}{2 hours}[/tex]
c= 45 miles per hour
Step-by-step explanation:
So you may see for each hour they are going 45 miles by dividing 2 by 2 and 90 by 2, so there constant of proportionality is 45 miles per hour. (answer 3 is the step by step)
Answers:
___ sold ___ more rings than ___
Jacob 5 lou
lou 8 jacob

15
Answer:
Lou sold 5 more earings than JacobStep-by-step explanation:
Step 1
Find 20% of 200
For fraction: divide 20 by 100 and remove the % sign.
[tex]{20}\%=\frac{20}{100}[/tex]
For decimal: move the decimal point 2 places to the left and remove the % sign.
[tex]{20}\%=0.2[/tex]
Multiply the decimal or fraction by the quantity that equals 100%
[tex]100[/tex]%[tex]=200[/tex]
[tex]\frac{20}{100} *200=0.2*200=40[/tex]
20% of 200 is 40
Lou sold 40 rings
Step 2
Find how much more or less earings did Lou sell than Jacob
40-35=5
So Lou sold 5 more rings than Jacob
Final Answer:Lou sold 5 more earings than Jacob

Answer:6
Step-by-step explanation:
Heron's Formula is: area = sqrt(s(s-a)(s-b)(s-c)) and s is the semiperimeter
Putting the side lengths in would be:
s = (a + b + c)/2
area = sqrt(6(6-5)(6-4)(6-3)) = sqrt(6*1*2*3) = 3*sqrt(2)
So the answer is 3*sqrt(2) which is equal to 6
Answer:
6 units²
Step-by-step explanation:
You want the area of the 3-4-5 right triangle.
AreaThe area formula for a triangle is ...
A = 1/2bh
where b represents the "base" and h represents the "height". The height is always measured to the vertex opposite the base, in direction perpendicular to the base.
Right triangleThe perpendicular legs of a right triangle have the necessary relationship for either one to be considered the "base", and the other to be the "height."
Here, that means we can call the side of length 3 units the "base" and the side of length 4 units the "height", or vice versa.
This means the area is ...
A = 1/2(3 units)(4 units) = 6 units²
__
Additional comment
Heron's formula for the area of a triangle based on all three side lengths can be used for this, but is more work than necessary.

Set u:Step 4: Integrate Pt. 3
[Integral] Apply Integration Method [U-Substitution]:Step 5: Integrate Pt. 4
Identify variables for u-substitution for the 1st integral.
Use another variable besides u to avoid confusion with earlier substitutions.
Set v:Step 6: Integrate Pt. 5
Solve the 1st integral using basic integration techniques listed under "Calculus":
[tex]\displaystyle \begin{aligned}\int\limits^{x = 1}_{x = 4} {\cos (u - e)} \, du & = \int\limits^{x = 1}_{x = 4} {\cos v} \, dv \\& = \sin v \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (u - e) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (x) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin 1 - \sin 4\end{aligned}[/tex]
Step 7: Integrate Pt. 6
To solve the 2nd integral, we use the same methods as "Step 6":
[tex]\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \int\limits^{x = 1}_{x = 4} {\frac{\sin e \sin u + \cos e \cos u}{u}} \, du \\& = \sin e \int\limits^{x = 1}_{x = 4} {\frac{\sin u}{u}} \, du + \cos e \int\limits^{x = 1}_{x = 4} {\frac{\cos u}{u}} \, du \\& = \sin (e) \text{Si} (u) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (u) \bigg| \limits^{x = 1}_{x = 4} \\\end{aligned}[/tex]
[tex]\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \sin (e) \text{Si} (x + e) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (x + e) \bigg| \limits^{x = 1}_{x = 4} \\& = \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) \bigg] + \bigg[ \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\\end{aligned}[/tex]
Step 8: Integrate Pt. 7
Combine our 2 integral values to obtain a final answer:
[tex]\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - e \int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du \\\begin{aligned}& = \sin 1 - \sin 4 - e \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) + \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\& \approx \boxed{0862854} \\\end{aligned}[/tex]
∴ we have evaluated the given special definite integral.

ANSWER; x = 131/333
Answer:
[tex]x=\dfrac{131}{333}[/tex]
Step-by-step explanation:
Assign the decimal to a variable:
Let [tex]x=0.\overline{393}[/tex]
Multiply both sides by 1000:
[tex]\implies x \cdot 1000=0.\overline{393} \cdot 1000[/tex]
[tex]\implies 1000x=393.\overline{393}[/tex]
Subtract the first equation from the second to eliminate the part after the decimal:
[tex]\begin{array}{r r c r}& 1000x & = & 393.\overline{393} \\\\- & x & = & 0.\overline{393} \\\\\cline{2-4} \\& 999x & = & 393 \\\end{array}[/tex]
Divide both sides by 999:
[tex]\implies \dfrac{999x}{999}=\dfrac{393}{999}[/tex]
[tex]\implies x=\dfrac{393}{999}[/tex]
Reduce the fraction:
[tex]\implies x=\dfrac{393 \div 3}{999 \div 3}[/tex]
[tex]\implies x=\dfrac{131}{333}[/tex]
