Answer:
b) [tex]d[/tex] = 84 miles
c) [tex]h[/tex] = 14.3 hours
Step-by-step explanation:
Given that:
The speed of Colton is constant while riding a bike.
Formula for speed is given as:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
If speed is constant, then we can deduct that:
[tex]Distance \propto Time[/tex]
Time = 3.5 hours
Distance = 49 miles
Therefore, the speed will be equal to:
Speed = [tex]\frac{49}{3.5}[/tex] = 14 miles/hr
b) Given that:
Time = 6 hours, then we have to find the distance to be hiked if the speed is same.
[tex]14 = \dfrac{d}{6}\\\Rightarrow d = \bold{84}\ miles/hr[/tex]
c) Given that:
Distance = 200 miles
Number of hours = [tex]h[/tex]
To find, the value of [tex]h[/tex].
[tex]14 = \dfrac{200}{h}\\\Rightarrow h = \dfrac{200}{14}\\\Rightarrow h = \bold{14.3}\ hours[/tex]

(iii) − − ____________________________________
(iv) − ________________________________
(v) −5y
Answer:
-5y
Step-by-step explanation:
We are to simplify the expression
5x - 5(y+x)
Open the bracket by applying the distributive law;
5x-(5(y)+5(x))
5x - (5y+5x)
5x - 5y - 5x
Collect like terms to have:
5x - 5x - 5y
0-5y
= -5y
Hence the simplified form is -5y

Answer:
B.
Step-by-step explanation:
The original equation is cos 64 = 32/k. To solve for k we need to isolate it. we can multiply by k then divide by cos 64. This gives us the equation k = 32/cos 64. Therefore, B is the right answer.
Megan ran 9/12 of a mile and skips a 12th of a mile around the track how far around the track did Megan go in total use the benchmarks fraction 1/2 1 and 0 to help you estimate each answer before you solve
Answer:
She went a total of 5/6 of a mile around the track
Step-by-step explanation:
Here, we want to calculate the distance around the track travelled
From the question, we are told that she ran 9/12 of a mile and skipped 1/12
So the total distance covered will be;
9/12 + 1/12 = 10/12 = 5/6
Ray and 3 friends played with a remote-control car for a total of 105 minutes. They each played with the car for the same amount of time. Which statement about the amount of time Ray and his friends spent playing with the car is true?
Answer:
Time Taken by each = 26 min 15 sec
Step-by-step explanation:
Given:
Total time play = 105 min
Total number of friends = 1+3 = 4
Each play equal
Find:
Time Taken by each
Computation:
Time Taken by each = Total time play / Total number of friends
Time Taken by each = 105 / 4
Time Taken by each = 26 min 15 sec
What is the answer to this equation: 40+40-20x0+3+125=
Answer:
208
Step-by-step explanation:
20 × 0 = 0
40 + 40 = 80
125 + 3 = 128
The given expression [tex]40+40-20\times 0+3+125[/tex] is reduced to 208 and this can be determined by using the arithmetic operations.
Given :
Expression - [tex]40+40-20\times 0+3+125[/tex]
The following steps can be used to evaluate the given expression:
Step 1 - Write down the expression.
[tex]=40+40-20\times 0+3+125[/tex]
Step 2 - First, multiply -20 by 0 in the given expression.
[tex]=40+40-0+3+125[/tex]
Step 3 - Now, Add 40 and 40 in the above expression.
= 80 + 3 + 125
Step 4 - Add 80 and 3 in the above expression.
= 83 + 125
Step 5 - Add 83 and 125 in the above expression.
= 208

What is the image of the point (-6,-8) after a rotation of 90° counterclockwise about the origin?
Answer:
(6,-8)
Step-by-step explanation:
By rotating the point (-6,-8) Counterclockwise you get the point (6,-8)
Hope it helps
The new coordinates after rotation will be - P'(8, -6)
We have a Point on a X - Y plane as P(-6, -8) which is rotated by 90° counter clockwise about the origin.
We have to determine the image of this point after the rotation.
What do you understand by Rotation of a Point in X - Y plane?
A rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.
According to the question, we have -
A point with coordinates → P(-6, -8)
Any point (say A[x, y]) when rotated 90° counter clockwise about the origin, then its new coordinates become A'(-y, x).
Using this rule, the coordinates of the point after rotation of point by 90° counter clockwise about the origin will be → P'(8, -6)
Hence, the new coordinates will be - P'(8, -6)

The graph shows the amount of money left after buying video games. Find the slope of the line
Answer:
It’s -20
Step-by-step explanation:
The slope of the line is m = -20.
What is the slope?The ratio of the vertical and horizontal changes between two points on a surface or a line is known as the slope.
Note that the graph passes through points (2,80) and (4,40).
The formula for the slope of a line passing through the points (x₁,y₁) and (x₂,y₂) is:
m = (y₂-y₁)/(x₂-x₁)
Substitute the points (x₁,y₁) = (2,80) and (x₂, y₂) = (4,40) into the above equation:
m = (40 - 80)/(4 - 2)
m = -40/2
m = -20
Hence, the slope of the line is m = -20.

Find the x-intercept and the y-intercept of the line below. Click on "None" if applicable.
Answer:
x- intercept is -2
y-intercept is 3
Step-by-step explanation:
x - intercept is x = -2
y intercept is y = 3
This is dealing with x and y intercepts of straight line graphs.
In straight line graphs, the y - intercept is simply the point where the line touches the y - axis while the x-intercept is the point where the line touches the x-axis.
From the graph given, the line touches the y-axis at y = 3 while it touches the x-axis at x = - 2
Thus;
x - intercept is x = -2
y intercept is y = 3

slope = -2, y-intercept = 5
y ]
= [?]x + []
Answer:
y = -2x + 5
Step-by-step explanation:
The equation of a line is y = mx + c where m is the slope and c is the y-intercept. Since we already know the values, we can just put it into the equation.
y = mx + c
y = -2x + 5
Answer:
y = - 2x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2 and c = 5 , thus
y = - 2x + 5 ← equation of line

A builder is building a fence with 6 LaTeX: \frac{1}{4}1 4 inch-wide wooden boards, arranged side-by-side with no gaps. How many boards are needed to build a fence that is 150 inches long?
Answer:
24 boards
Step-by-step explanation:
From the above question, the width of a wooden board for a fence = 6 1/4 inches
How many boards are needed to build a fence that is 150 inches long?
This is calculated as:
6 1/4 inches = 1 board
150 inches = x
Cross Multiply
6 1/4 × x = 150 × 1
x = 150 ÷ 6 1/4
x = 150 ÷ 25/4
x = 150 × 4/25
x = 24 boards
Hence, 24 boards would be needed to build a fence that is 150 inches long

i really need help
Answer:
3.75 minutes
Step-by-step explanation:
Set up an equation where x is the number of minutes:
0.25x + 35 = 0.5x + 20
Solve for x:
0.25x + 35 = 0.5x + 20
35 = 0.25x + 20
15 = 0.25x
3.75 = x
So, both plans will cost the same with 3.75 minutes
