Answer:
6 pencils
Step-by-step explanation:
Total cost = paper * cost of a package + pencils * cost of a pencils
We bought 1 pack of paper at 3 dollars and p pencils at 2 dollars
15 = 1*3 + p*2
15 = 3+2p
Subtract 3 from each side
15-3 = 3+2p-3
12 = 2p
Divide by 2
12/2 = 2p/2
6 = p

What is the slope of a line that is perpendicular to the line y = -1/2x + 5
To find the slope of a line perpendicular to another line, we simply need to find the inverse negative of the slope of the first one. This makes sense if you visualize it on a graph or in your head.
The slope of the line given is -1/2.
To find the inverse negative we first inverse the number, then take then negatuve of that (or opposite order).
The inverse of -1/2 is, -2 (switch the numerator and denominator or do to the power of -1, ^-1).
The negative of -2 is, 2.
Therefore the slope of the line perpendicular to y = -1/2x + 5 is 2.
A bird weighs 10 N and is standing 3 m up whats its GPE
Answer:
30 J
Step-by-step explanation:
Given : -
Height ( h ) = 3m
Weight ( W ) = 10 N
To find : GPE = ?
Note : -
GPE is Gravitational Potential Energy.
It is expressed in Joules ( J ).
Formula : -
W = mg
mg = 10 N
Formula : -
GPE = mgh
GPE = 10 x 3
GPE = 30 J
Therefore,
A bird weighs 10 N and is standing 3 m, it's
GPE is 30 J.
Answer:
The answer is GPE = 300 Nm (Newton meters)
Step-by-step explanation:
The bird's mass weighs to 10 Newtons.
Presuming this took place on Earth, the gravitational force is 10 Newtons.
The bird is standing 3 meters above the ground.
Using the GPE formula (GPE = mgw,) the answer should be 300 Newton metres.

The graph represents function 1 and the equation represents function 2:
A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.
Function 2
y = 4x + 1
How much more is the rate of change of function 2 than the rate of change of function 1?
A)1
B)2
C)3
D)4
The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.
Step-by-step explanation:The rate of change is also known as slope. The slope of a linear function or a line is
It is given that the function 1 is passing through the points (0,3) and (4,3). Slope of function 1 is
Therefore the slope of first function is 0.
The slope intercept form of a line is
Where, m is the slope and b is y-intercept.
The second function is
Therefore the slope of second function is 2 and the y-intercept is 1.
The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

please help! Complete the function for this graph.
Answer:
y = - 2|x - (-2)| + 1
Step-by-step explanation:
The general form of an absolute value function is y = a|x – h| + k, where a ≠ 0.
The value of a determines whether the graph opens up or down. If a is negative, the graph opens down. This holds true, as the value of a = -2
The given graph for the absolute function has a vertex (h, k) of (-2, 1). This is the maximum point of the graph.
Therefore, the missing values on the given equation is the value of the vertex. It has to be written as y = - 2|x - (-2)| + 1 because the equation on your given problem is formatted according to the general form of the absolute value function, y = a|x – h| + k.

Step 1: Convert both mixed numbers into fractions.
2 3/4 = 11/4
3 5/6 = 23/6
Step 2: Find GCF by multiplying both fractions by opposing denominators
11/4 = 66/24 (11 * 6 = 66, 4 * 6 = 24)
23/6 = 92/24 (23 * 4 = 92, 6*4=24)
Step 3: Add both fractions
92/24 + 66/24 = 158/24
Step 4: Simplify
158/24= 79/12 = 6 7/12 miles

Answer:
[tex]2036.75088022^{2}[/tex] or [tex]2036.8^{2}[/tex] rounded to the nearest tenth
Step-by-step explanation:
1. Find the area of the base and the top, which are circles.
Area of circle : [tex]\pi 10^{2}[/tex] = 986.960440109
There are 2 circles, soooooo....= 986.960440109 x 2 = 1973.92088022
2. Find the rest of the area of the cylander.
So, we have to find the circumference of the circle.
Circumference :2[tex]\pi[/tex]10 = 62.83
3. Multiply circumference by height.
62.83 x 7 = 439.81
4. Add all of the products.
439.81 + 1973.92088022 = [tex]2036.75088022^{2}[/tex] or [tex]2036.8^{2}[/tex] rounded to the nearest tenth

**brianly pls
Step-by-step explanation:
50 = -1/3b + 20
what is b?
To find b, start by subtracting 20 from both sides:
50 = -1/3b + 20
-20 -20
30 = -1/3b
Now isolate b by dividing both sides by -1/3:
30/(-1/3) = (-1/3b)/(-1/3)
-90 = b
b is 90!

Answer:
1) x= -8
2) x=7
Step-by-step explanation:
1) x+88+x+108 = 180 ( co-interior angles)
=> 2x+ 196 = 180
=> 2x= 180-196
=> 2x= -16
=>x= -16/2
=>x= -8
2) 7x+6=8x-1
=>7x-8x= -1-6
=>-x= -7
=>x= 7
leni can decorate the room in 4 hours. her sister lucy do the same jobin 3 hours working together, how long will take them to finish the job
Fractions are integers that have both a numerator and a denominator. They are represented as; [tex]\frac{x}{y}[/tex]
Where:
x = Numerator
y = Denominator.
It will take them both [tex]\frac{7}{12}[/tex] hours or 0.583 hours to finish the job together.
To solve the above question, we would be applying the operations of the addition of fractions.
From the question,
Leni can decorate the room in 4 hours. This means in 1 hour, Leni can paint 1/4 of the room.
Lucy, her sister can decorate the room in 3 hours. This means in 1 hour, lucy can decorate 1/3 of the room.
Let us represent the number of hours it will take them both to decorate the room working together as "T"
Hence,
1/T = 1/4 + 1/3
Lowest Common Denominator for (3, 4 ) = 12
Hence,
1/T = 3 + 4 / 12
1/T = 7/12
Find the reciprocal of both sides
T = 7/12 hours or can be expressed in decimals as 0.583 hours.
Therefore, it will take them both [tex]\frac{7}{12}[/tex] hours or 0.583 hours to finish the job together.

Answer:
1. d 2. a 3. d 4. a 5. a
Step-by-step explanation:
For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.
2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.
3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.
4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.
5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.

Two students, Galen and Mai, worked on a project.
Galen worked for 3 2/3 hours.
Mai worked for 2 4/5 hours.
What was the total time spent on the project?
How much more time did Galen spend on the project than Mai?
Answer:
Mia worked 4/5 of an hour less than Galen.
or
Galen spent 4/5 of an hour more working on the project.
Step-by-step explanation:
First we have to find the LCM (Lowest Common Multiple) of 5 and 3 -
3: 3, 6, 9, 15, 18, 21, 24, 27, 30
5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
We can see here, that the lowest common multiple is 15.
Now we need to convert the 2/3 and 4/5 into fractions that are equivalent to something fraction that has the denominator of 15.
2/3x5= 10/15
4/5x3= 12/15
So, now, the hours of work time of both Galen and Mia are having the same denominator, now, we can subtract.
3 10/15 - 2 12/15 = 12/15
Now, we understand that 12/15 was the amount of time Galen worked more than Mai. But, still, there is still more to do.
Suspense......
SIMPLIFY!!!
12/15 both come in 3's multiplication table.
12/15 divided by 3 = 4/5
Now, our final answer simplified is 4/5.
