Answer:
5mile per hourStep-by-step explanation:
Step one:
given data
distance= 1/4mile
time taken= 1/20 hour
Step two:
Required
speed
we know that speed is
speed= distance/time
substituting
speed= 1/4/1/20
speed=1/4*20/1
speeed=20/4
speed=5mile/hour
The option a sis correct, the speed is 5mile per hour

Answer:
2
Step-by-step explanation:
m is the slope = rise/run
take any 2 easi points on the line, for example (0,0) and (1,2)
to get from (0,0) to (1,2) you had to rise 2 and go run 1 so the slope is
m=2/1=2

Can someone explain how to do this?
thanksss <33
Answer:
True True False True
Step-by-step explanation:
You would substitute the value for x and the value for y into both equations and see if the sign holds true.
So for number 1:
x=3, y=-2;
y ≤ x -3
-2 ≤ x - 3
-2 ≤ -1
y ≥ -x - 2
-2 ≥ -3 - 2
-2 ≥ -5
Number 1 is true because the equations are true ^^
Do this for every problem so it would be:
1. True
2. True
3. False
4. True

Since 50% of the people chose A with the first group of surveyed people, 100 more will choose that because 125 is half of 250
If the transformation was a rotation, tiffany can or cannot be certain the trapezoids are congruent?
Answer: Tiffany can be certain the trapezoids are congruent.
Step-by-step explanation: Two figures are congruent when their corresponding angles are equal and they have the same shape and size.
A figure can go thorugh 3 types of transformations:
Rotation: the figure is turned around a fixed point;Reflection: is created by fliping over the figure over a line;Translation: move the figure to another location, without changing its size;As long the figure doesn't change its size or shape, it doesn't matter if it's rotated, reflected or translated, they will be congruent.
When the trapezoid was rotated creating another one, the two shapes didn't change its size or shape, so Tiffany can be certain they are congruent.

Please walk me through the steps, I understand most of it I just forgot how to do it
Answer:
x=8
Step-by-step explanation:
first you need to find the unknown corner so you do 180-71= 109
then find the interior angle degree (n-2)*180 (n=number of sides) so (4-2)*180=2(180)=360
then set everything equal to 360:
10x+6+13x-2+8x-1+109=360
(combine like terms)
31x+112=360
(subtract 112 form both sides)
31x=248
(divide both sides by 31)
x=8

The formula to convert a temperature from degrees Fahrenheit (F˚) to degrees Celsius (C˚) is C˚=59F˚−1609. 1) Write a formula to convert from degrees Celsius to degrees Fahrenheit by solving for F˚ in the equation above. 2) Are the equations from the problem statement and from part 1 inverses? EXPLAIN
Answer:
Step-by-step explanation:
Given the formula to convert a temperature from degrees Fahrenheit (F˚) to degrees Celsius (C˚) as C˚=5/9F˚−1609.
To write the formula to convert °C to °F , we will make °F the subject of the formula
Add 1609 to both sides of the equation
C˚+1609=5/9F˚−1609.+1609
C+1609 = 5/9F
Cross multiply
9(C+1609) = 5F
Divide both sides by 5
9/5 (C+1609) = F
Hence the formula to convert from degrees Celsius to degrees Fahrenheit is 9/5 (C+1609) = F.
B) To check whether they are inverses we need to check if F(C) = C(F)
To get F(C) we will substitute F into C as shown;
F = 9/5 (C+1609)
C˚=5/9F˚−1609.
F(C) = 9/5 ((5/9F˚−1609.)+1609)
F(C) = 9/5 * 5F/9 -1609 + 1609
F(C) = 9/5 * 5F/9
F(C) = 45F/45
F(C) = F
Similarly for C(F)
C(F) = (5/9(9/5 (C+1609))˚−1609.
C(F) = (C+1609) - 1609
C(F) = C
This shows that both equations are inverses of each other

2(P +1) + 3(P + 2 ) > 2
need help pls
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
[tex]2\left(P\:+1\right)\:+\:3\left(P\:+\:2\:\right)\:>\:2[/tex]
solving the expression
[tex]2\left(P\:+1\right)\:+\:3\left(P\:+\:2\:\right)\:>\:2[/tex]
as
[tex]2\left(P+1\right)+3\left(P+2\right)=5P+8[/tex]so the expression becomes
[tex]5P+8>2[/tex]
subtracting 8 from both sides
[tex]5P+8-8>2-8[/tex]
[tex]5P>-6[/tex]
Dividing both sides by 5
[tex]\frac{5P}{5}>\frac{-6}{5}[/tex]
[tex]P>-\frac{6}{5}[/tex]
Therefore,
[tex]2\left(P+1\right)+3\left(P+2\right)>2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:P>-\frac{6}{5}\:\\ \:\mathrm{Decimal:}&\:P>-1.2\\ \:\mathrm{Interval\:Notation:}&\:\left(-\frac{6}{5},\:\infty \:\right)\end{bmatrix}[/tex]

find the slope of the line graphed
Answer: it would be C, -5/3
since slope = rise/run, or y2-y1/x2-x1 (either way works)
Answer:
the answer is C
Step-by-step explanation:
slope = rise/run, or y2-y1/x2-x1
You rise 5 to get to the point thats on the Y axis and you run left 3 to hit the point on the Y axis, so since you had to run left, that means its going to be negative but if you run right, the answer will be positive. i hope that helped :)
