Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.
Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
She walked 3 miles at a velocity of 6 miles per hour, thus [tex]d = 3, v = 6[/tex]. The time is:[tex]v = \frac{d}{t}[/tex]
[tex]t = \frac{d}{v} = \frac{3}{6} = 0.5[/tex]
Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.Distance of 3 miles, velocity of 2 miles per hour, thus [tex]d = 3, v = 2[/tex]. The time she took to return, in hours, is:[tex]t = \frac{d}{v} = \frac{3}{2} = 1.5[/tex]
1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

HELP ASAP! Pls and thx! Need help.
Answer:
y = -3x + 22
Step-by-step explanation:
To find m, find the change in y and divide it by the change in x.
For example, the change in y between 19 and 13 is -6. Then determine the change in x. For example, since we determined the change in 19 and 13, let's look at the change in the x coordinates that pair with 19 and 13: 1 and 3. The change in x between 1 and 3 is 2. Now divide the change in y by the change in x: -6/2 = -3. So now we have the equation y = -3x + b, but we still need to figure out b, or the y-intercept. To do this, we need to figure out a pattern in the table to find out what y is equal to when x = 0, the definition of a y-intercept. From just the table alone, it looks like for every 2 units the x-coordinate decreases, the y-coordinates increases by 6. We could also just as easily say that for every 1 unit the x-coordinate decreases, the y-coordinate increases by 3. From this definition, if we look at the coordinate (1, 19), if we were to decrease 1 from the x-coordinate, we would have to increase the y-coordinate by 3 which we can write as (x - 1, y + 3). So, we would get (0, 22). So, when x = 0, y = 22.

how can i put this in a graph and a table
Answer:
y=2.49x+24.99

y= Total cost of her birthday party
2.49= The price of each ice cream cone
x= The number of ice cream cones she buys
24.99 = The price of the birthday cake
You move left 6 units. You end at (-4, 4). Where did you start?
(you need a coordinate plane)
Answer:

Let the graph of g be a translation 4 units down followed by a reflection about the y-axis of the graph of f(x)=−3x +2
Write a rule for g.
Answer:
[tex]g(x)=f(-x)-4[/tex]
Step-by-step explanation:
Hi there!
We're given that [tex]f(x)=-3x +2[/tex].
g(x) is f(x) translated 4 units down. Subtract 4 from f(x):
[tex]g(x)=f(x)-4[/tex]
It is also reflected about the y-axis. This makes all values of x negative:

The sum of three consecutive odd integers is 237.what are the integers
Answer:
let the 1st number be x
then second number is x+2
then third number is x+2+2
according to question
sum of three consecutive odd integers is 237.
hence, x+x+2+x+2+2=237
3x+6=237
3x=237-6
3x=231
x=231/3
x=77
therefore 1st integer is 77
2nd integer is 77+2=79
3rd integer is 77+2+2=81
Answer:
77, 79, 81
Step-by-step explanation:
You can represent the equation as follows:
x + x + 2 + x + 4 =237
Combine like terms.
3x + 6 = 237
Subtract 6 from both sides.
3x = 231
Divide both sides by 3.
x = 77
Now, add 2 to 77 to determine the second integer.
77 + 2 = 79
Add 4 to 77 to determine the third integer.
77 + 4 = 81
∠1 and ∠2 are complementary angles. m∠1 is 5y+32 and m∠2 is 7y-14. Find m∠2 & show your work.
it was deleted last time I posted it???
[tex]\\ \sf\longmapsto 5y+32+7y-14=90[/tex]
[tex]\\ \sf\longmapsto 12y+18=90[/tex]
[tex]\\ \sf\longmapsto 12y=72[/tex]
[tex]\\ \sf\longmapsto y=6[/tex]
m<2=7(6)-14=42-14=28[/tex]The required value of m∠2 would be 30 degrees when the value of y = 6 due to the given pair of angles being complementary.
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles.
We have been given that the pair of angles as
(5y + 32)° and (7y - 14)°
∵ ∠1 and ∠2 are complementary angles
Here, the pairing of angles sums up to 90° then they are called complementary angles.
So 5y + 32 + 7y - 14 = 90°
⇒ 12y + 18 = 90
⇒ 12y = 72
⇒ y = 6
So m∠2 = 7y - 14
Substitute the value of y = 6 in the above equation, and we get
So m∠2 = 7(6) - 14 = 42 -12 = 30
Therefore, the value of m∠2 would be 30 degrees when the value of y = 6.

d. angle d = ____
e. These angles together make a complete rotation/a circle.What do you get when you add all the angles together.What does this number have to do with a circle?
Answer:
Step-by-step explanation:
Angle a = 35°
Angle b = 40°
Angle c = 35°
Angle d = 70°
When you add all the angles together, you get 360°. This number has to do with a circle because 360° is the total number of degrees in a circle, half of a circle would be 180°.
Hope this helps!
Answer:
∠a = 35
∠b = 40
∠c = 35
∠d = 70
Step-by-step explanation:
∠b = 40 {Vertical angles are congruent}
∠d = 70 {Vertical angles are congruent}
∠1 = ∠ a
∠2 = ∠c
∠1 = ∠2
So, ∠1 =∠2 = ∠a = ∠c
70 + 40 + ∠a + ∠2 = 180 {Straight line angle}
110 + 2∠a = 180 {∠a =∠2}
2∠a = 180 - 110
∠a = 70/2
∠a = 35
∠1 =∠2 = ∠a = ∠c = 35
e) When we add all the angles, we get 360.
