Complete question:
Russell has a collection of 1,200 pennies. Of these pennies, 25% are dated before 1980, 35% are dated from 1980 to 2000, and the rest are dated after 2000. How many pennies in Russell’s collection are dated after 2000?
Answer:
480 pennies
Step-by-step explanation:
Total pennies = 1200
Datwd before 1980 = 25%
Dated 1980 - 2000 = 35%
The rest are Dated after 2000 ;
How many are dated after 2000
Dated before 1980 = 25% ;
25% of 1200
0.25 * 1200 = 300
Dated 1980 - 2000 = 35% ;
0.35 * 1200 = 420
Dated after 2000 ;
1200 - (300 + 420)
1200 - 720
= 480 pennies

He made 50 dollars in 4 weeks so divide that equally amongst each week you get 12.5
The rate of change of money in his savings account per week is 12.5
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We have, After 4 weeks, he had $350 dollars and after 9 weeks, he had
$412.50.
So, We can consider it as (4, 350) and (9, 412.5)
So, the rate of change is
=(412.5-350)/ (9-4)
= 62.5
= 12.5
Hence, the rate of change is 12.5.

Brylee has hiked 125 feet and hikes 1 foot per second. Jeremiah has hiked 10 feet and hikes 3.5 feet per second. After how many seconds will Brylee and Jeremiah have hiked the same amount of feet?
Answer:
46 seconds
Step-by-step explanation:
Brylee has hiked 125 feet and hikes 1 foot per second.
125 + s
Jeremiah has hiked 10 feet and hikes 3.5 feet per second.
10 + 3.5s
Where
s = number of seconds
Equate both Brylee and Jeremiah expression
125 + s = 10 + 3.5s
Collect like terms
125 - 10 = 3.5s - s
115 = 2.5s
Divide both sides by 2.5
s = 115 / 2.5
= 46
s = 46 seconds

The fifth-grade students at Hawthorne Elementary School made an art project using two shapes of pasta. The students used 9 times as many elbow noodles as bowtie noodles. They used a total of 3,230 pieces of pasta. How many bowtie noodles did the students use?
Answer:
2,907 pieces of bowtie noodles was used by the student
Step-by-step explanation:
Here, we want to calculate the number of pieces of bowtie noodles use
Let the number of elbow noodles used be x
The number of bow tie noodles used is 9 times this and that will be 9 * x = 9x
Adding both together, we have 9x + x = 10x
Thus;
10x = 3230
x = 3230/10
x = 323 pieces
The number of pieces of bowtie noodles used will be 323 * 9 = 2,907 pieces
At time x=0, water begins to drip steadily out of a water tank. After 3 hours , there are 6.8 gallons of water in the tank. After 9 hours, 4.4 gallons remain. Write a linear function rule that models the number of gallons of water y left in the tank for any number of hours x. The linear function rule is y = ___
Answer:
[tex]y=-0.4x+8[/tex]
Step-by-step explanation:
Let the Linear Function to represent the drip of water out of the water tank be:
[tex]y=mx+c[/tex]
Where [tex]x[/tex] is the time
[tex]y[/tex] is the number of gallons at that time
[tex]m[/tex] is the rate at which water drips
[tex]c[/tex] is the initial number of gallons of water in the tank
Putting the given values in the above equation:
[tex]6.8 = m\times 3+c ..... (1)[/tex]
[tex]4.4 =m\times 9+c..... (2)[/tex]
Subtracting (1) from (2):
[tex]6m=-2.4\\\Rightarrow m =-0.4[/tex]
Putting in equation (1):
[tex]6.8=-0.4\times 3+c\\\Rightarrow c = 8[/tex]
Therefore, the linear function equation to represent in the situation is:
[tex]y=-0.4x+8[/tex]

Describe a rigid motion or composition of rigid motions that maps the rectangular bench at (10,0) and the adjacent flagpole onto the other short rectangular bench and flagpole
Answer:
The answer is below
Step-by-step explanation:
Describe a rigid motion or composition of rigid motions that maps the rectangular bench at (0,10) and the adjacent flagpole onto the other short rectangular bench and flagpole
Solution:
The other short rectangular bench is at (0, -10), while the short flagpole at (2, 10)
Transformation is the movement of a point from its initial location to a new location. If an object is transformed then all its points are also transformed. Types of transformation are reflection, dilation, rotation and translation.
If a point X(x, y) is reflected across the x axis, the new point is (x, -y)
If a point X(x, y) is reflected across the y axis, the new point is (-x, y)
Therefore the rectangular bench at (0,10) is reflected across the x axis to give the other short rectangular bench at (0, -10) while the adjacent flagpole at (-2,10) is reflected across the y axis to give the other flagpole at (2, 10)

Answer:
slope: 4/3
Midpoint: (2,-2)
distance : 20
Step-by-step explanation:
you can find the slop by m=y2-y1/x2-x1
m= 6-(-10)/8-(-4) m=4/3
use the midpoint formula: (x₁ + x₂)/2, (y₁ + y₂)/2 and we get (2,-2)
distance formula- [tex]\sqrt{(x2-x1)+(y2-y1)[/tex]
the distance is the square root of 400 which is 20
