HURRY THIS IS MY LAST THING FOR THIS ASSIGNMENT. Maria is using a coordinate plane with the axes labeled only with integers. She says that the point (−0.5, 2) cannot be plotted because halves are not numbered on the x-axis. Write a note to Maria about her misunderstanding and explain how to plot the point.
Answer: You can have halves of points, Just because I have 0 units and 1 units doesn't mean that I can't put a point in the middle of the two. You could put a point in the middle of a unit for 0 - 1 it would be 0.5. You would place it in the middle of the unit

Determine the length of a chord whose central angle is 65° in a circle with a radius of 9 feet.
Question 5 options:
1)
4.84 feet
2)
9 feet
3)
9.67 feet
4)
8.16 feet
Answer:
3)
9.67 feet
Step-by-step explanation:
The length of the chord is approximately 8.16 feet. The correct option is 4.
What is the length of the chord of the circle?A line segment connecting two points on a circle is referred to as a circle's chord in geometry. The circle's center is traversed by the longest segment that can be drawn between any two points on the circle.
To get the chord's length, we can utilize the formula for a circle's chord length. The equation is:
Length of chord = 2r sin(θ/2)
where r is the circle's radius, is its radian central angle, and sin is the sine function.
First, we need to convert the central angle from degrees to radians:
θ = 65° = (65/180)π = 1.14 radians
Now we can plug in the values:
Length of chord = 2(9 feet) sin(1.14/2) ≈ 8.16 feet
Therefore, the length of the chord is approximately 8.16 feet.

Troy and Lisa were shopping for school supplies. Each purchased different quantities of the same notebook and thumb drive. Troy bought 4 notebooks and 5 thumb drives for $116. Lisa bought 2 notebooks and 3 thumb drives for $68. Find the cost of each notebook and each thumb drive.
Answer:NOTEBOOK= 4
THUMB DRIVE=20
Step-by-step explanation:
The cost of thumbdrive and notebook purchased are $20 and $4 respectively
Let :
Cost of Notebooks = n
Cost of Thumb drive = t
Troy :
4n + 5t = 116 - - - - (1)Lisa :
2n + 3t = 68 - - - - (2)Solving by elimination :
Multiply (1) by 2 and (2) by 4
8n + 10t = 232 - - - (3)8n + 12t = 272 - - - (4)Subtract (3) and (4)
-2t = - 40t = 40 ÷ 2 = 20From (1)
4n + 5(20) = 1164n + 100 = 1164n = 116 - 1004n = 16n = 16 ÷ 4 = 4Hence, cost of notebook is $4 and cost of thumbdrive is $20

Five years ago, Mark was twice as old as Max. In three years, Max's age will be 2/3 that of Mark. What is the sum of their ages now
Answer:
4years
Step-by-step explanation:
Let the present age of Mark be x
Let the present age of Max be y
Five years ago
Mark = x-5
Max = y - 5
If mark was twice as old as Max, then;
x - 5 = 2(y-5)
x-5 = 2y - 10
x-2y = -10+5
x - 2y = -5 ... 1
In three years,
mark = x+3
Max = y+3
Now if Max's age will be 2/3 that of Mark, then;
x+3 = 2/3(y+3)
3(x+3) = 2(y+3)
3x + 9 = 2y+6
3x-2y = -3 .... 2
Solve 1 and 2 simultaneously
x - 2y = -5 ... 1
3x-2y = -3 .... 2
From 1: x = -5 + 2y
Substitute into 2:
3(-5+2y) - 2y = -3
-15 + 6y - 2y = -3
-15 + 4y = -3
4y = -3 + 15
4y = 12
y = 3
Recall thet x = -5+2y
x = -5+2(3)
x = -5 + 6
x = 1
The sum of their ages will be x+y
x+y = 1+3
x+y = 4
Hence the sum of their ages now is 4years
What is the answer for
3days : 18hrs
Answer:
4 : 1
Step-by-step explanation:
(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.
1 day = 24 hours, 3 days = (3 × 24) hours
3 days = 72 hours
Now both the units are same, so we can easily simplify now.
72 hours : 18 hours
36 : 9 = 12 : 3

how many sides does a regular polygon have if the measure of an interior angle is 160 degrees? justify ur answer EXPLAIN HOW PLSSS
Step-by-step explanation:
Size of Interior angle = 180° - 360°/n, where n is the number of sides of the regular polygon.
We have 180° - 360°/n = 160°.
=> 360°/n = 20°, n = 18.
Therefore it is a 18-sided regular polygon.

What percentage of the shape is purple?
Write your answer using a percent sign (%).
(Please help!) almost done 3
Okay, we see that there are 10 pieces in the circle - thus, it is our denominator. Next, we see that 9 out of them are coloured in. Therefore, the fraction is 9/10. To express our answer as a percent, we need to divide 9 and 10 to get 0.9. Then, we multiply 0.9 by 100 to get 90%. As a result, your answer is 90%.
The percentage of the shape that is purple is approximately 90%.
To find the percentage of the shape that is purple, we need to calculate the proportion of purple pieces out of the total number of pieces and express it as a percentage.
Given that there are 10 pieces in total and 9 of them are colored in, we can calculate the percentage as follows:
Percentage of purple pieces = (Number of purple pieces / Total number of pieces) × 100
Percentage of purple pieces = (9 / 10) × 100
Percentage of purple pieces = 0.9 × 100
Percentage of purple pieces = 90%
Therefore, the percentage of the shape that is purple is approximately 90%.

A bouncy ball is dropped such that the height of its first bounce is 6.25 feet and each
successive bounce is 80% of the previous bounce's height. What would be the height
of the 11th bounce of the ball?
Answer:
0.67 feet
Step-by-step explanation:
This question can be interpreted as find the 11th term of a geometry progression where a = 6.25 and r = 80%
So, we have:
[tex]T_n = ar^{n-1}[/tex]
In this case:
[tex]r - 80\% = 0.8[/tex]
[tex]n = 11[/tex]
So, we have:
[tex]T_{11} = 6.25 * 0.8^{11-1}[/tex]
[tex]T_{11} = 6.25 * 0.8^{10}[/tex]
[tex]T_{11} = 6.25 * 0.1073741824[/tex]
[tex]T_{11} = 0.67ft[/tex]
Hence, the height of rebound at the 11th time is approximately 0.67

A bottie contains 255 coins.
1/3 of the coins are £1 coins.
110 of the coins are 50p coins.
The rest of the coins are 20p coins.
Work out the total value of the coins contained in the bottle.
Answer:
£152
Step-by-step explanation:
Solution:
Find out how much is 1/3 of 255 coins:
255 x 1/3 = 85
Since you know how many 50p and £1 coins there are, the remaining of the coins after the 50p and £1 get deducted from the total coins.
255 - 85 - 110 = 60
There are 60 20p coins, 85 £1 coins and 110 50p coins.
Find out the total value by calculating them all altogether.
60 x 20p = 1200
85 x 100p which is £1 = 8500
110 x 50p = 5500
I did them separately so that it wouldn't be so confusing.
Convert them into £, then after that add them up.
£12 + £85 + £55 = £152
