I guess the meaning is that after 3 more days the week will be over, and she has to reach her goal by then.
x = the average number of miles to ride each of the 3 days
x = (34.1 - 14)/3
the solution is
x = 20.1/3 = 6.7 miles
Now, determine whether the relationship between the two triangles you found in the first task is true for any two triangles. For any line, if you draw two right triangles using the line as the hypotenuse, can the triangles be congruent? Why or why not? Do they have to be congruent? Why or why not?
Answer:
The two triangles are not congruent.
Step-by-step explanation:
If two right triangles are drawn with a line as hypotenuse, the two triangles are not congruent. Because as per RHS congruency ie Right Angle - Hypotenuse - Side : right angle, hypotenuse & also one other side equality is needed for congruence. Given case doesn't satisfy the last 'other side equality' condition.

the sum of two consecutive odd numbers is 80 find the numbers
Answer: The two numbers are 39 and 41
==================================================
Work Shown:
x = some odd number
x+2 = next odd number
eg: x = 3 and x+2 = 3+2 = 5
Add up those two expressions, set the sum equal to 80, and solve for x
(x) + (x+2) = 80
2x+2 = 80
2(x+1) = 80
x+1 = 80/2
x+1 = 40
x = 40-1
x = 39
----------
Another way to solve is to do this
2x+2 = 80
2x = 80-2
2x = 78
x = 78/2
x = 39
-----------
Either way, the solution is x = 39 which means the next odd number up is x+2 = 39+2 = 41
To check the answer, add up the two values
39+41 = 80
This confirms we have the right answer.

Step-by-step explanation:
Some friends of yours collected books for a book drive. They collected 64 Fiction, and 48 Non-Fiction books. They asked you to make bundles of books so that all the books get sent to families who want them and all of the bundles have the same content inside. How many bundles of books can your team send? How many fiction books will you need to put in each bundle? How many non-fiction books will you need to put in each bundle?
As all of the bundles have the same content inside, so assuming that there is x number of Fiction books and y number of Non-fiction books in each bundle.
Let n be the total number of bundles that my team can send.
There are 64 Fiction books, so
nx=64 ...(i)
Or x=64/n ...(ii)
also, there are 48 Non-Fiction books, so
ny=48 ...(iii)
Or y=48/n ...(iv)
Observing that the numbers x, y, and n are counting numbers and from equations (i) and (iii), n is the common factor of 64 and 48.
The possible common factors of 64 and 48 are,
n=1,2,4,8, and 16.
So, my team can send 1,2,3,4,8 or 16 bundles of books.
Now, from equations (ii) and (iv),
For n=1:
x=64/1=64
y=48/1=48
So, for 1 bundle the number of Fiction and Non-fictions books are 64 and 48 respectively.
For n=2:
x=64/2=32
y=48/2=48
So, for 2 bundles, the number of Fiction and Non-fictions books are 32 and 24 respectively.
For n=4:
x=64/4=16
y=48/4=12
So, for 4 bundles, the number of Fiction and Non-fictions books are 16 and 12 respectively.
For n=8:
x=64/8=8
y=48/8=6
So, for 8 bundles, the number of Fiction and Non-fictions books are 8 and 6 respectively.
For n=16:
x=64/16=4
y=48/16=3
So, for 16 bundles, the number of Fiction and Non-fictions books are 4 and 3 respectively.

write the equation for the function that has the shape of f(x)=x^3 but is moved three units to the left, seven units upward, and then reflected in the x-axis?
Answer:
The first transformation occurs when we add a constant d to the parent function \displaystyle f\left(x\right)={b}^{x}f(x)=b
x
, giving us a vertical shift d units in the same direction as the sign. For example, if we begin by graphing a parent function, \displaystyle f\left(x\right)={2}^{x}f(x)=2
x
, we can then graph two vertical shifts alongside it, using \displaystyle d=3d=3: the upward shift, \displaystyle g\left(x\right)={2}^{x}+3g(x)=2
x
+3 and the downward shift, \displaystyle h\left(x\right)={2}^{x}-3h(x)=2
x
−3. Both vertical shifts are shown in Figure 5.
Graph of three functions, g(x) = 2^x+3 in blue with an asymptote at y=3, f(x) = 2^x in orange with an asymptote at y=0, and h(x)=2^x-3 with an asymptote at y=-3. Note that each functions’ transformations are described in the text.
Figure 5
Observe the results of shifting \displaystyle f\left(x\right)={2}^{x}f(x)=2
x
vertically:
The domain, \displaystyle \left(-\infty ,\infty \right)(−∞,∞) remains unchanged.
When the function is shifted up 3 units to \displaystyle g\left(x\right)={2}^{x}+3g(x)=2
x
+3:
The y-intercept shifts up 3 units to \displaystyle \left(0,4\right)(0,4).
The asymptote shifts up 3 units to \displaystyle y=3y=3.
The range becomes \displaystyle \left(3,\infty \right)(3,∞).
When the function is shifted down 3 units to \displaystyle h\left(x\right)={2}^{x}-3h(x)=2
x
−3:
The y-intercept shifts down 3 units to \displaystyle \left(0,-2\right)(0,−2).
The asymptote also shifts down 3 units to \displaystyle y=-3y=−3.
The range becomes \displaystyle \left(-3,\infty \right)(−3,∞).
Graphing a Horizontal Shift
The next transformation occurs when we add a constant c to the input of the parent function \displaystyle f\left(x\right)={b}^{x}f(x)=b
x
, giving us a horizontal shift c units in the opposite direction of the sign. For example, if we begin by graphing the parent function \displaystyle f\left(x\right)={2}^{x}f(x)=2
x
, we can then graph two horizontal shifts alongside it, using \displaystyle c=3c=3: the shift left, \displaystyle g\left(x\right)={2}^{x+3}g(x)=2
x+3
, and the shift right, \displaystyle h\left(x\right)={2}^{x - 3}h(x)=2
x−3
. Both horizontal shifts are shown in Figure 6.
Graph of three functions, g(x) = 2^(x+3) in blue, f(x) = 2^x in orange, and h(x)=2^(x-3). Each functions’ asymptotes are at y=0Note that each functions’ transformations are described in the text.
Figure 6
Observe the results of shifting \displaystyle f\left(x\right)={2}^{x}f(x)=2
x
horizontally:
The domain, \displaystyle \left(-\infty ,\infty \right)(−∞,∞), remains unchanged.
The asymptote, \displaystyle y=0y=0, remains unchanged.
The y-intercept shifts such that:
When the function is shifted left 3 units to \displaystyle g\left(x\right)={2}^{x+3}g(x)=2
x+3
, the y-intercept becomes \displaystyle \left(0,8\right)(0,8). This is because \displaystyle {2}^{x+3}=\left(8\right){2}^{x}2
x+3
=(8)2
x
, so the initial value of the function is 8.
When the function is shifted right 3 units to \displaystyle h\left(x\right)={2}^{x - 3}h(x)=2
x−3
, the y-intercept becomes \displaystyle \left(0,\frac{1}{8}\right)(0,
8
1
). Again, see that \displaystyle {2}^{x - 3}=\left(\frac{1}{8}\right){2}^{x}2

Which fraction is equal to 0.25.?
Answer: 1/4
Step-by-step explanation:
Hope this helps
The 0.25 is equivalent to 1/4, where the numerator is 1 and the denominator is 4.
The fraction that is equal to 0.25 is 1/4. To understand this, examine the decimal representation of 0.25. The decimal point separates the whole number part from the fractional part. In 0.25, the digit 2 is in the tenths place, and the digit 5 is in the hundredths place. As a fraction, the number 2 in the tenths place can be written as 2/10, and the number 5 in the hundredths place written as 5/100. Simplifying these fractions, find that 2/10 reduces to 1/5 and 5/100 reduces to 1/20.

Answer:
x=8.2
Step-by-step explanation:
First, figure out which trig function you are going to use.
In this problem you are dealing with the opposite side to the angle and the hypotenuse, and if you remember SOH CAH TOA, this requires sine.
sin (55) =opposite/hypotenuse
sin (55) =x/10
multiply both sides by 10 to get 10 * sin (55) = x

17. A group of college students is volunteering for Help the Homeless during their spring break. They are putting the finishing touches on a house they built. Working alone, Irina can paint a certain room in 9 hours. Paulo can paint the same room in 8 hours. Write an equation that can be used to find how long it will take them working together to paint the room. How many hours will it take them to paint the room? If necessary, round your answer to the nearest hundredth.
Answer:
4.24 hours
Step-by-step explanation:
Irina can paint 1/9 of a room in 1 hour since she can paint a room in 9 hours. 1/9x, where x is the number of hours she works and 1/9 of a room per hour is her speed, would be her part of the calculation.
Paulo can paint 1/8 of a room in 1 hour since he can paint an entire room in 8 hours. 1/8x, where x is the number of hours he works and 1/8 of a room per hour is his speed, would be his part of the equation.
1/9x + 1/8x = 1 (Irina's portion of the room plus Paulo's portion of the room equals one complete room) would be the equation.
Look for a denominator that has the same value as the numerator. Both 9 and 8 split evenly into 72 as the initial number. We multiply the top of 1/9 by 8 to convert the fraction and get 8/72x because 9*8 = 72. We multiply the top of 1/8 by 9 to convert the fraction and get 9/72x because 8*9 = 72. We have 8/72x+9/72x=1 currently.
17/72x=1
÷ both sides by 17/72:
17/72x ÷ 17/72 = 1÷17/72
∴ x=1/1 * 72/17
∴ x=72/17= 4.24

Answer:
a = 9 + b - c → D
Step-by-step explanation:
To cancel the square root of one side of an equation square the two sides
Examples:
If [tex]\sqrt{x}[/tex] = 5, to find x square the two sides to cancel the square root
([tex]\sqrt{x}[/tex] )² = (5)², then x = 25
If [tex]\sqrt{a+b}[/tex] = 7, to find a + b square the two sides to cancel the square root
([tex]\sqrt{a+b}[/tex] )² = (7)², then a + b = 49
Now let us solve the question
To solve it for a square the two sides then keep a on the left side and move b, c to the other side
∵ [tex]\sqrt{a-b+c}[/tex] = 3
→ Square the two sides to cancel the square root
∴ ([tex]\sqrt{a-b+c}[/tex])² = (3)²
∴ a - b + c = 9
→ Add b to both sides to move b from the left side to the right side
∴ a - b + b + c = 9 + b
∴ a + c = 9 + b
→ Subtract c from both sides to move c from the left side to the right side
∴ a + c - c = 9 + b - c
∴ a = 9 + b - c
