Avril cycles 10 km at x km/h and then 14 km at y km/h. Express the time for the journey as a single fraction
Step-by-step explanation:
It is given that,
Avril cycles 10 km at x km/h and then 14 km at y km/h.
We need to express the time for the journey as a single fraction.
We know that,
Speed = distance/time
or
time = distance/speed
Here, total distance = 10 +14 = 24 km/h
Total speed = x+y
So,
[tex]t=\dfrac{24}{x+y}[/tex]
Hence, this is the required solution.

Step-by-step explanation:
2x - x + 7 = x + 3 + 4
Answer:0
Step-by-step explanation:
Simplifying
2x + -1x + 7 = x + 3 + 4
Reorder the terms:
7 + 2x + -1x = x + 3 + 4
Combine like terms: 2x + -1x = 1x
7 + 1x = x + 3 + 4
Reorder the terms:
7 + 1x = 3 + 4 + x
Combine like terms: 3 + 4 = 7
7 + 1x = 7 + x
Add '-7' to each side of the equation.
7 + -7 + 1x = 7 + -7 + x
Combine like terms: 7 + -7 = 0
0 + 1x = 7 + -7 + x
1x = 7 + -7 + x
Combine like terms: 7 + -7 = 0
1x = 0 + x
1x = x
Solving
1x = x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
1x + -1x = x + -1x
Combine like terms: 1x + -1x = 0
0 = x + -1x
Combine like terms: x + -1x = 0
0 = 0
Simplifying
0 = 0

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 31 hours and the median is 27.2 hours. Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 7th percentile of the data is 16 hours. Step 2 of 5 : Approximately how many families are in the sample
Answer:
There are approximately 343 families in the sample.
Step-by-step explanation:
xth percentile:
A measure is said to be in the xth percentile if it is greater than x% of the measures.
Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 7th percentile of the data is 16 hours.
This means that 7% of the sample size n is 24. So
[tex]0.07n = 24[/tex]
[tex]n = \frac{24}{0.07}[/tex]
[tex]n = 342.86[/tex]
Rounding up, there are approximately 343 families in the sample.

Write equivalent fraction with the given denominator.
Answer:
20/10
Step-by-step explanation:
2x10=20
Answer:
2 = 20/10
Step-by-step explanation:
The problem wants you to write a fraction that is equalavent to 2, but that has 10 as the denominator. I chose 20, because 2 x 10 = 20.
A bus travels 6/8 of a mile in 12 of a minute. How far will it travel in one minute?
Find the unit rate and simplify. Show all work.
Answer:
1/16 of a mile in one minute.
Step-by-step explanation:
1. you know that 3/4 mile = 12 mins and x mile = 1 min
2. To get 12 mins to 1 you divide the mins by 12
3. So you do the same for miles!
4. 3/4 miles divided by 12
5. which turns into 3/4 * 1/12
6. so your final answer would be 1/16 of a mile in one minute

Write the equation of the line in slope intercept form equation of the line in slope intercept form is blank
Answer:
y=70x+20
Step-by-step explanation:
Okay so the slope is determined by having two points on the line in this case one of them is (0,20) and (2,160), you're going 140 up and 2 over so the slope would be [tex]\frac{140}{2}[/tex] which equals 70 so thats how you get m, to get b you simply put the y interecept which is at 20.
Plugs those numbers together you get y=70x+20 which is intercept form.

Answer:4124966.126
Step-by-step explanation:
Distance between star from the sun is d = 4124966.128 AU
What is Trigonometry?
Trigonometry is the branch of mathematics that deals with particular angles functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle.
The astronomical unit distance between the star and the Sun can be calculated using the trigonometric function.
As per the given data:
distance from Earth to the Sun (P) = 1 AU
θ = 0.00001389 degrees
From tanθ:
tanθ = P/B
{P = perpendicular and B = base}
From the diagram:
tanθ = 1/d
tan(0.00001389) = 1/d
d = 1/tan(0.00001389)
d = 4124966.128 AU
The separation between the sun and the star is d = 4124966.128 AU.

3/2 ∜(2(x-6)^3 )+4=16
Answer:
x ≈ 18.7
Step-by-step explanation:
This is a big equation, so let's break it down a bit.
[tex]\frac{3}{2} \sqrt[4]{(2(x-6) ^3 )} +4=16[/tex]
Let's start by isolating the radical which is x.
So subtract 4 from both sides :
[tex]\frac{3}{2} \sqrt[4]{(2(x-6) ^3)}[/tex][tex]=12[/tex]
Now multiply both sides by 2 to get rid of the fraction :
[tex]3\sqrt[4]{(2(x-6)^3)} = 24[/tex]
Now divide both sides by 3 to get rid of the number out of the poly root :
[tex]\sqrt[4]{2(x-6) ^3}[/tex][tex]=8[/tex]
Now take both sides of the equation to the power of 4 :
[tex]2x^3 - 36x^2+216x-432=4096[/tex]
And lastly, solve :
[tex]x = 18.69920[/tex] which is rounded up to [tex]x[/tex] ≈ [tex]18.7[/tex]
