Answer:
343
Step-by-step explanation:
There are quarters(25¢), loonies ($1), and toonies ($2)
And total number of coins is 9
If loonies ($1), and toonies ($2) are one, then quarters(25¢) is 7
If quarters(25¢), and toonies ($2) are one, then loonies ($1)is 7
If loonies ($1), and quarters(25¢) are one, then toonies ($2) is 7
So possible number number of combination for an item that cost between $10 and $12 is
= 1^3 * 1^3 * 7^3
= 343
hope this helps, stay safe :)
The number of different combinations of coins could Teo use to pay for an item that costs between $10 and $12 is 17.
What are Combinations?Combinations are defined as the arrangement of objects or numbers in a way such that the order of the arrangement does not matter.
Given that,
Teo has a combination of quarters, loonies, and toonies in his pocket.
Total number of coins = 9
1 quarter = $0.75
1 loonie = $1
1 toonie = $2
If he uses fewer toonies than loonies,
Total number of combinations of 9 coins = 1³ × 1³ × 7³ = 343
We need the number of combinations in between $10 and $12.
We can form the following combinations.
(2 × $1) + $2 gives $4. Remaining can be 8, 9 and 10 quarter coins.
(3 × $1) + (2 × $2) gives $7. Remaining can be 4, 5 and 6 quarter coins.
(3 × $1) + (1 × $2) gives $5. Remaining can be 7, 8 and 9 quarter coins.
(4 × $1) + (3 × $2) gives $10. Remaining can be 1 or 2 quarter coins.
(4 × $1) + (2 × $2) gives $8. Remaining can be 3, 4 and 5 quarter coins.
(4 × $1) + (1 × $2) gives $6. Remaining can be 6, 7 and 8 quarter coins.
Total number of combinations = 3 + 3 + 3 + 2 + 3 + 3 = 17
Hence the total number of combinations are 17.

A painting measures 1 meter by 2 meters. A frame shop charges $30.00 per meter for a wooden frame. How much would it cost to buy a frame for the painting?
Answer:
$180.00
Step-by-step explanation:
The painting is rectangular and it measures 1 meter by 2 meters. The frame shop charges $30.00 per meter for a wooden frame.
To find the cost, we need to find the perimeter of the painting and then multiply it by the cost of a wooden frame per meter.
The perimeter of a rectangle is:
P = 2(L + B)
P = 2(1 + 2) = 2 * 3 = 6 m
The cost of the frame is therefore:
6 * 30 = $180.00

1. What is the median?
2. What is the mean?Show your work.
3. What is the typical height of a Knicks basketball player? Explain.
Answer:
median = 80 inches
mean = 79.692 inches
typical height = 80 inches
Step-by-step explanation:
Given height
84, 80, 87, 75, 77, 79, 80, 74, 76, 80, 80, 82, 82
arranging the height in increasing order we have
74,75,76,77,79,80,80,80,80,82,82,84,87
no, of terms in the heights = 13
We know
that median for any data set is the middle number, if data is arranged in increasing order of their occurrence.
If the number of terms is odd, then median is (n+1)/2 th term
If the number of terms is even, then median is taken average of n/2 th term and( n/2 + 1)th term .
________________________________________
since here number of term is 13.
then median will be (13+1)/2 th term
i.e 7th term
as shown above seventh term is 80.
1. What is the median?
answer: Median is 80
_____________________________________
Mean is calculated average of all the terms
mean = sum of all the terms/ number of terms
mean = 74+75+76+77+79+80+80+80+80+82+82+84+87/13
= 1036/13 = 79.692
Thus, means is 79.692
2. What is the mean?
Answer: Mean is 79.692
3. What is the typical height of a Knicks basketball player? Explain
Answer: Typical height for basket ball player will the height which is the most commonly occurring height in the group.

What statement is false choose from the letters above that match the statements :-)
Please help guys!
Thanks
Answer:
Option C
Step-by-step explanation:
A "tessellation" is a flat covering of 2D geometric shapes. A shape in a tessellation is called a "tile".
Tessellations can be in a pattern that goes 'forever', and they cannot overlap. This eliminates A and D, since they are true.
A "tessellation" cannot have any spaces. This eliminates option B, since this is true. Since a circle and an eclipse have curved sides, they can not tessellate on their own. Regular pentagons and octagons will also not tessellate on it's own. Any shape that are put together and leave a gap will not tessellate.
I have attached a picture showing why circles and pentagons will not tessellate.
So, not any 2D shape would tessellate. Option C's statement is false.
Option C should be the correct answer.

area of square is 4*4 =16
area of half of circle is
(Pi*r²)/2 = 3.14*4/2 = 6.28
16+6.28 = 22.28
Answer:
C. 22.28

4 x 4 = 16 (Pi x r²)/2 = 3.14 x 4/2 = 6.28
16 + 6.28 = 22.28
Two rectangular pyramids are similar. The smaller pyramid has a volume of 12 cubic feet, and
the larger pyramid has a volume of 324 cubic feet. If the smaller pyramid has a height of 6 feet,
what is the exact height (in feet) of the larger pyramid?
Volume of Big Pyramid= 324 cubic feet
Volume of small pyramid= 12
Volume of a pyramid is given as V=⅓xBasexheight
For the big pyramid
324=⅓xbasexheight
But 324= 27x12
Then for the big pyramid,
12=1/3x1/27xbasexheight
For the small pyramid
12=1/3xbasex6
Since both base are similar and from the equations derived so far
1/3x1/27xheight=1/3x6
Height=27x3x1/3x6=162feet

For 30 persons or fewer $10 per person. For every additional person $9 per person.Irene paid the company $390 for her department event. How many people did she cater for?
Answer:
She catered for 40 people.
Step-by-step explanation:
According to the information given, you can write an equation that indicates that 30 people multiply for its cost that is $10 plus the number of people after 30 for its cost that is $9 is equal to $390. According to this, the equation is:
10(30)+9x= 390, where
x= number of people after 30
Then, you can solve for x:
300+9x= 390
9x=390-300
9x= 90
x=90/9
x=10
The answer is that she catered for 40 people, 30 people at a cost of $10 and 10 people for a cost of $9.

Answer:
a) [tex]x = 10^{18}\,\mu m^{2}[/tex], b) [tex]x = 10^{18}[/tex], c) [tex]x = 10^{21}\,\mu m^{2}[/tex], d) [tex]x = 10^{21}[/tex], e) [tex]x = \frac{1}{10^{21}}[/tex], f) [tex]x = 10^{3}\,nm^{2}[/tex], g) [tex]x = 10^{3}\,nm^{2}[/tex]
Step-by-step explanation:
a) The product of one terameter and one micrometer is:
[tex]x = (1\,tm)\cdot (10^{12}\,\frac{m}{tm})\cdot (10^{6}\,\frac{\mu m}{m} ) \cdot (1\,\mu m)[/tex]
[tex]x = (10^{18}\,\mu m)\cdot (1\,\mu m)[/tex]
[tex]x = 10^{18}\,\mu m^{2}[/tex]
b) The quotient of one terameter and one micrometer is:
[tex]x = \frac{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{6}\,\frac{\mu m}{m} )}{1\,\mu m}[/tex]
[tex]x = \frac{10^{18}\,\mu m}{1\,\mu m}[/tex]
[tex]x = 10^{18}[/tex]
c) The product of terameter and one nanometer is:
[tex]x = (1\,tm)\cdot (10^{12}\,\frac{m}{tm})\cdot (10^{9}\,\frac{nm}{m} ) \cdot (1\,nm)[/tex]
[tex]x = (10^{21}\,nm)\cdot (1\,nm)[/tex]
[tex]x = 10^{21}\,\mu m^{2}[/tex]
d) The quotient of one terameter and one nanometer is:
[tex]x = \frac{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{9}\,\frac{nm}{m} )}{1\,nm}[/tex]
[tex]x = \frac{10^{21}\,nm}{1\,nm}[/tex]
[tex]x = 10^{21}[/tex]
e) The quotient of one nanometer and one terameter is:
[tex]x = \frac{1\,nm}{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{9}\,\frac{nm}{m} )}[/tex]
[tex]x = \frac{1\,nm}{10^{21}\,nm}[/tex]
[tex]x = \frac{1}{10^{21}}[/tex]
f) The quotient of one nanometer and one micrometer is:
[tex]x = \frac{1\,nm}{(1\,\mu m)\cdot (10^{3}\,\frac{nm}{\mu m} )}[/tex]
[tex]x = \frac{1\,nm}{10^{3}\,nm}[/tex]
[tex]x = \frac{1}{10^{3}}[/tex]
g) The product of one nanometer and one micrometer is:
[tex]x = (1\,nm)\cdot (1\,\mu m)\cdot (10^{3}\,\frac{nm}{\mu m} )[/tex]
[tex]x = 10^{3}\,nm^{2}[/tex]

Answer:
Function 2.
Step-by-step explanation:
For the first equation, the y-intercept is the 'b' value in the equation
y = mx + b.
In the equation given, b = 5. This is the y-intercept for the equation.
To find the y-intercept, you need to look for the 'y' value at x = 0. Therefore:
In the table, notice that when t = 0, r = 5.25. This is the same as x = 0, y = 5.25. This means that the y-intercept of the table is y = 5.25.
Since 5.25 > 5, function 2 has a greater y intercept.
