pie for her sisters. Larissa cuts the apple pie into eights and serves the five slices for her
brothers. Then, she cuts the pumpkin pie into sixths and serves three pieces to her sisters. Her
brothers and sisters eat all of the pie they are served, and nothing more.
At the end of the night, Larissa plans to put all of the leftover slices of pie together in the same
pie pan if there is enough space.
Which of the following statements is NOT true?
a) There will be enough space to fit the leftover slices of pie together in one of the pie pans
b) There will be more empty space in the pumpkin pie pan than in the apple pie pan after the
slices are served
c) After Larissa served the apple pie, there is exactly 0.375 of the apple pie remaining
d) After putting the pies together in one pan, 1/8 of the pie pan would still be empty
Answer:
All the statements are correct.
Step-by-step explanation:
Larissa is baking two pies that are the same size:
an apple pie for her brothers and a pumpkin pie for her sisters.
Larissa cuts the apple pie into eights and serves the five slices for her brothers.
This means she divided the apple pie into 1/8, so 5 for a brothers = 5(1/8) = 5/8
The amount of apple pie left is = 1 - 5/8
= 3/8
Then, she cuts the pumpkin pie into sixths and serves three pieces to her sisters.
She divided the pumpkin pie into 1/6
Serving her 3 sisters = 3(1/6)
= 3/6
The amount left = 1 - 3/6 = 3/6 = 1/2
This means, her sisters are 1/2 of the pie and 1/2 is left
Her brothers and sisters eat all of the pie they are served, and nothing more.
Verifying the given options
a) There will be enough space to fit the leftover slices of pie together in one of the pie pans
Yes, this is correct it we put the left over slices of pie in the pumpkin pie pan.
Option a is correct.
b) There will be more empty space in the pumpkin pie pan than in the apple pie pan after the slices are served.
Option b) is true
This is because, the amount of space left in the pumpkin pie pan = 1/2
The amount of space left in the apple pie pan = 3/8
1/2 is greater than > 3/8
c) After Larissa served the apple pie, there is exactly 0.375 of the apple pie remaining.
Larissa served, 5/8 of the apple pie,
3/8 is left , 3/8 = 0.375.
Option c is correct.
d) After putting the pies together in one pan, 1/8 of the pie pan would still be empty
Yes, if the left over pies are put in the pumpkin pie pan.
This is because, the amount of space left in the pumpkin pie pan = 1/2
The amount of space left in the apple pie pan = 3/8
1/2 + 3/8
= 4+3/8 = 7/8
1 - 7/8 = 1/8
Option d is correct
Therefore, all the 4 statements are correct.

Answer:
80.67 ft/secStep-by-step explanation:
Mile to feet
1 mi = 5280 feetHour to seconds
1 hr = 60 min = 60*60 sec =3600 secSpeed of the car
55 mi/hr = 55*5280 ft / 3600 sec = 80.67 ft/sec rounded to two decimal places-Maggie turned right out of the school and drove 5 miles East to the store. She left the store and drove 2 miles North to Pelican's, then drove 5 miles South to her friend's house. When it was time to pick up her brother, she drove 7 miles West, then drove 4 miles North. Maggie and her brother then drove 2 miles East to get home. What is the displacement from Maggie's home to school?
Answer:
The school is at displacement of 1 mile towards South from the home.
Step-by-step explanation:
Let the origin, O, represents the location of the school.
Now, observe the attached figure for all the displacements as:
She drove 5 miles East to shore ( to point A)
So, OA=5 miles.
Then she drove 2 miles North to Pelican's ( to point B)
So, AB=2 miles.
Then she drove 5 miles South to her friend's house ( to point C)
So, BC=5 miles.
Then she drove 7 miles West, to point D,
So, CD=7 miles.
Then she drove 4 miles North, to point E,
So, DE=4 miles.
Lastly, she drove 2 miles East, to reach home (the point F)
So, EF=2 miles.
Now computing the displacements in each direction.
The displacements in the East direction=OA+EF= 5+2= 7 miles
The displacements in the West direction =CD= 7 miles
As East and West are opposite to east other, so net displacements in the East direction = 7+(-7)=0, i.e the final point F ( home) is on the vertical axis as shown.
The displacements in the North direction=AB+DE= 2+4= 6 miles
The displacements in the South direction=BC=5 miles
As North and South are opposite to east other, so net displacements in the North direction = 6+(-5)= 1 miles which means final point F ( home) is located at 1 mile towards North from the school.
Hence, the school is at displacement of 1 mile towards South from the home.

The inequality that best describes this problem is 3.5p ≤ 40;
Given parameters:
Total amount with me = $40
Cost per package of hot dog = $3.5
Unknown;
The inequality that represents the problem = ?
Solution:
p is the number of hotdogs that can be bought.
So, total hotdog that can be bought if each hotdog cost $3.5 per box is;
p x 3.5
Now,
this will equal the total amount at hand;
p x 3.5 ≤ 40

What is the equation in point slope form for a linear function with a slope of m=−4 that passes through the point (2,−7)?
Answer: y+7=-4(x-2)
Step-by-step explanation:
point slope formula is y-y1=m(x-x1)
it gives you m = -4
(x1,y1) = (-1,-7)
y-(-7) = -4(x-2)
negative of a negative number is positive
y+7=-4(x-2)
you leave that as your answer because thats what point slope for is
its in that form ^
The equation in point slope form for a linear function is [tex]y=4x+15[/tex]
Given the following points:
Points on the x-axis = 2 Points on the y-axis = -7 Slope, m = -4
To write an equation in point slope form for a linear function:
The standard form of an equation of line is given by the formula;
[tex]y-y_1=m(x-x_1)[/tex]
Where:
x and y are the points. m is the slope.Substituting the given parameters into the formula, we have;
[tex]y-(-7)=-4(x-2)\\\\y+7=4x-8\\\\y=4x-8+7\\\\y=4x+15[/tex]
