Tyler is an avid cyclist he bikes 117 miles every 3 days how many miles will he cycle in 8 days also I need the numerical answer only
Answer:
He will bike 312 miles in 8 days.
Step-by-step explanation:
You divide total miles (117) by total time (3) which is 39, multiple that by 8 and you get your answer of 312.
What are the 5 Key components for graphing the Parabola of a Quadratic Function?
Answer:
Axis of symmetry
y-intercept
x-intercepts
Vertex
(I forgot the last one)
Step-by-step explanation:
Find the slope and y-intercept.
Answer:
y-intercept = -5, slope = 5/3
Step-by-step explanation:
The y-intercept is where on the y-axis (vertical line) does the graph cross. The slope can be found many different ways. My method for this graph was simply counting up the graph until I got to the point where the graph crosses another whole number on the x-axis and then counted over. This makes sense because slope is rise over run so if you go up 5 (from the y-intercept) and then over 3 (to get to the next whole number point) then your slope is 5/3
Please help i dont wanna fail this time
Answer:
Step-by-step explanation:
So...
you would add -4 and -2 1/2 giving the total of -6 1/2.
All thats left is for you to graph it:)
(Please mark brainliest)
Answer:
-4 - 2.5 = -6.5
Step-by-step explanation:
We are taking a Negative 4 (-4) and subtracting it by 2/5 (Minus 2,.5 or - 2.5).
This results us with -6.5
The arrow would be placed on the mark in between the -7 and -6 going RIGHT. ->

ANSWER ASAP . BE RIGHT TO BE THE BRAINLIEST
Answer:
9 1/9
Step-by-step explanation:
Least Common Denominator is 18.
4 7/9= 4 14/18
1 5/6= 1 15/18
2 1/2= 2 9/18
4 14/18+ 1 15/18+ 2 9/18= 7 38/18

My cookbook says that a salad sauce should be made of 1/3 lemon juice and
2/3 oil. I put 30 ml of oil but my hand slipped when adding the lemon juice
and the total volume is now 70.
How much oil must I now add to have the correct proportions?
Answer:
50ml
Step-by-step explanation:
as u put 30ml oil and u have 70 so 70-30 is 40 which is 40ml lemon juice. as 1 part is lemon and 2 parts oil out 2x40 so 80ml but as u already have 30 in there only put 50 :)

Step-by-step explanation:
Quadrilateral BECK is known to be a rhombus. Two of the vertices are B(3,5) and C(7,-3).
a. Find one slope of diagonal EK
b. Find an equation of line EK
Answer:
a. The slope of EK is [tex]\frac{1}{2}[/tex]
b. The equation of line EK is y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The form of the equation of a line is y = m x + b, where
m is the slope of the lineb is the y-interceptThe rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineThe rule of the mid-point is ([tex]\frac{x1+x2}{2},\frac{y1+y2}{2}[/tex])∵ BECK is a rhombus
∵ The diagonal is the line that joins two opposite vertices
∵ B and C are opposite vertices in the rhombus
∵ E and K are opposite vertices in the rhombus
∴ BC and EK are the diagonals of the rhombus BECK
∵ The diagonals of the rhombus are ⊥ and bisect each other
∴ EK is ⊥ bisector to BC
→ Let us find the slope and the mid-point of BC
∵ B = (3, 5) and C = (7, -3)
∴ x1 = 3 and y1 = 5
∴ x2 = 7 and y2 = -3
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{-3-5}{7-3}[/tex] = [tex]\frac{-8}{4}[/tex] = -2
∴ m = -2
∴ The slope of BC = -2
→ To find the slope of EK reciprocal the slope of BC and change its sign
∴ m⊥ = [tex]\frac{1}{2}[/tex]
∴ The slope of EK = [tex]\frac{1}{2}[/tex]
a. The slope of EK is [tex]\frac{1}{2}[/tex]
→ Substitute the value of the slope in the form of the equation above
∵ y = [tex]\frac{1}{2}[/tex] x + b
→ To find b substitute x and y in the equation by the coordinates
of a point on the line
∵ The mid-point of BC is the mid-point of EK
∵ The mid-point of BC = ([tex]\frac{3+7}{2},\frac{5+-3}{2}[/tex]) = ([tex]\frac{10}{2},\frac{2}{2}[/tex]) = (5, 1)
∴ The mid-point of EK = (5, 1)
→ Substitute x by 5 and y by 2 in the equation
∵ 1 = [tex]\frac{1}{2}[/tex](5) + b
∴ 1 = [tex]\frac{5}{2}[/tex] + b
→ Subtract [tex]\frac{5}{2}[/tex] from both sides
∴ [tex]-\frac{3}{2}[/tex] = b
→ Substitute the value of b in the equation
∵ y = [tex]\frac{1}{2}[/tex] x + [tex]-\frac{3}{2}[/tex]
∴ y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{3}{2}[/tex]
b. The equation of line EK is y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{3}{2}[/tex]

What is the least common multiple of 2x^2 and 4x+12
Answer:
4 x ^2 ( x + 3 )
Step-by-step explanation:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.
If line segment AB represents 25%, what is the length of a line segment that is 100%?
If I am correctly understanding the question, I think the length of the line segment would be 4AB
Step-by-step explanation:
25% = 1/4
AB = 1/4
100% = 4/4
AB*4 = 4AB
Multiply AB by 4 to find the value that 100% would equal, resulting in 4AB.

which relation is NOT a function?
Answer:
The relation represented by diagram 4 is NOT a function.
Step-by-step explanation:
To tell if a relation is not a function, pay attention to the x-intercepts. If there is more than one y-intercept with the same x-intercept, then it is not a function, because a function can only have one output (y-value) for each input (x-value).
According to the fourth diagram, the domains include 1, 2, and 3 while the range includes A, B, and C. Also, the ordered pairs would go as follows according to the arrows:
(1, A), (2, A), (2, B), (3, C)
While the y-values, A and B, are different, they share the same input, 2. Therefore, the relation represented by the 4th diagram is NOT a function.
Hope this helps!
