Phoebe knit a hat for a friend. She started with 197 meters of yarn. When she finished, she had 8,200 centimeters of yarn left over. How much yarn did Phoebe use to knit the hat? Write your answer in centimeters.
Answer:
Phone used 11,500 centimeters of yarn
Step-by-step explanation:
So first we know that 1 meter is equivalent to of 100 centimeters
Now lets convert everything into centimeters
197*100=19700
And thats it
Now we know she started with 19700 centimeters of yarn and has 8200 centimeters left over.
We can make an equation
We can make “x” stand for amount of yarn used.
19700-x=8200
Minus x becuase thats how much she used and equal 8200 becuase Thats what was left over
Now use inver operations
-x=-11,500
Now divide - on both sides
x=11,500
She used 11,500 centimeters of yarn
Answer: 11,500 centimeters of yarn

11. In the diagrams below the rows of green tiles are surrounded by white tiles
Find a formula for the number of white tiles which would be needed to
surround a row of n green tiles.
Hii please help!!! Show work
Step-by-step explanation:
There are 12 white tiles surrounding 3 green tiles, and 16 white tiles surrounding 5 green tiles.
Common difference = (16-12)/(5-3) = 2.
Hence number of white tiles = 2n + 6.
Find the base angles of the figure below.
A.) 72°
B.) 108°
C.) 36°
D.) 54°
Answer:
36
Step-by-step explanation:
The angles of a triangle have a sum of 180 degrees. This is an isosceles triangle indicated by the red markers on sides ED and EF. This means that the sides and angles are congruent.
Subtract 108 from 180 and divide that by 2.
180-108 = 72
72/2 = 36
If x and (x+50°) are complementary angles. find the angles
Step-by-step explanation:
When the sum of two angles is equal to 90 degrees, they are called complementary angles.
So
x + x + 50° = 90°
2x = 90° - 50°
2x = 40°
x = 40°/2
x = 20°
x + 50 = 20 + 50 = 70°
Hope it helps :)
Answer:
let 1st angle be x
and another angle be x+50°
two angles are said to be complementary,if the some of their measures is 90°
so,
x+x+50=90
2x+50 =90
2x=90-50
x=40/2
:-x= 20 ....... 1st angle
another angle (x+50)=20+50=70°

if x= (4/5)^-2 divided by (1/4)^2,find the value of x^-1
Answer:
[tex]\displaystyle x^{-1}=\frac{1}{25}[/tex]
Step-by-step explanation:
We are given the value of x:
[tex]x= (4/5)^{-2}[/tex] divided by [tex](1/4)^2[/tex]
We need to find the reciprocal of x or:
[tex]\displaystyle x^{-1}=\frac{1}{x}=\frac{\frac{1}{4}^2}{\frac{4}{5}^{-2}}[/tex]
Operating:
[tex]\displaystyle x^{-1}=\frac{1}{4}^2*\frac{5}{4}^{-2}[/tex]
[tex]\displaystyle x^{-1}=\frac{1}{16}*\frac{16}{25}[/tex]
[tex]\mathbf{\displaystyle x^{-1}=\frac{1}{25}}[/tex]

What's the next number? 0 , 1/3 , 1/2 , 3/5 , 2/3
Answer:
The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 is 5/7
Step-by-step explanation:
The given numbers are;
0, 1/3, 1/2, 3/5, and 2/3
The number sequence is formed adding [tex]\dfrac{1}{\left (\dfrac{n^2 + n}{2} \right ) }[/tex] to each (n - 1)th term to get the nth term number in the sequence, with the first term equal to 0, as follows;
For the 2nd term, the (n - 1)th term is 0, and n = 2, gives;
The
[tex]0 +\dfrac{1}{\left (\dfrac{2^2 + 2}{2} \right ) } = 0 + \dfrac{1}{3} = \dfrac{1}{3}[/tex]
For the 3rd term, the (n - 1)th term is 1/3, and n = 3, gives;
[tex]\dfrac{1}{3} +\dfrac{1}{\left (\dfrac{3^2 + 3}{2} \right ) } = \dfrac{1}{3} + \dfrac{1}{6} = \dfrac{1}{2}[/tex]
For the 4th term, the (n - 1)th term is 1/2, and n = 4, gives;
[tex]\dfrac{1}{2} +\dfrac{1}{\left (\dfrac{4^2 + 4}{2} \right ) } = \dfrac{1}{2} + \dfrac{1}{10} = \dfrac{3}{5}[/tex]
For the 5th term, the (n - 1)th term is 3/5, and n = 5, gives;
[tex]\dfrac{3}{5} +\dfrac{1}{\left (\dfrac{5^2 + 5}{2} \right ) } = \dfrac{3}{5} + \dfrac{1}{15} = \dfrac{2}{3}[/tex]
For the next or 6th term, the (n - 1)th term is 2/3, and n = 6, gives;
[tex]\dfrac{2}{3} +\dfrac{1}{\left (\dfrac{6^2 + 6}{2} \right ) } = \dfrac{2}{3} + \dfrac{1}{21} = \dfrac{15}{21} = \dfrac{5}{7}[/tex]
The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 = 5/7.

Twenty seconds after a plane in the air show- dives, it is 300 feet from where it begin. At what rate is the plane diving
Answer:
15 feets per second
Step-by-step explanation:
Given that:
Distance traveled by plane = 300 feets
Time taken by plane to travel such distance = 20 seconds
Rate at which the plane is diving is obtained thus :
Distance / time
= 300 feets / 20 seconds
= 15 feets / second
Hence, the plane is diving at a rate of 15 feets per second.

Solve. Show your work in the sketchpad. Don't forget your dollar sign and to round to the nearest hundredth. You have to do this, it's money. For every hour that John works he earns $8.55. If John works 13.5 hours, how much money did he make?
Answer:
$115.43
Step-by-step explanation:
From the above question:
1 hour of work = $8.55
13.5 hours of work = x
Cross Multiply
x = 13.5 × $8.55
x = $115.425
Approximately to the nearest hundredth = $115.43
If John works 13.5 hours, the amount of money he makes = $115.43
Find the unit price of each item, rounding answers to the nearest tenth of a cent. A) 4 lbs for $2.37 b) 15 lbs for $8.57 c) 25 lbs for $13.59 Which bag (4, 15, or 25) is the best deal?
Answer:
A. $0.59
B. $0.57
C. $0.54
The best deal is 25 lbs for $13.59
Step-by-step explanation:
A) 4 lbs for $2.37
Units price (price per lb) = $2.37 / 4
= $0.5925
Approximately $0.59
b) 15 lbs for $8.57
Price per lb = $8.57 / 15
= $0.5713
Approximately $0.57
c) 25 lbs for $13.59
Price per lb = $13.59 / 25
= $0.5436
Approximately $0.54
Which bag (4, 15, or 25) is the best deal?
The best deal is 25 lbs for $13.59

Answer:
The equation in the point-slope form for the line that passes through point (-1, -4) and has a slope of -3 is y+4=-3(x+1).
Step-by-step explanation:
Given that:
Line passes through the point = (-1, -4)
Slope of the line = -3
Point slope form of a line is given by;
[tex]y-y_1=m(x-x_1)[/tex]
Here,
x1 = -1 , y1 = -4 and m = -3
Putting the values in the point-slope form of the equation,
y-(-4) = -3(x-(-1))
y+4= -3(x+1)
Hence,
The equation in the point-slope form for the line that passes through point (-1, -4) and has a slope of -3 is y+4=-3(x+1).

Item 18 Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers? Item 18 Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers?
Answer:
11 and 12
Step-by-step explanation:
Let the consecutive integers be x and x+1
The lesser integer = x
The greater integer = x+1
Two times the greater of two consecutive integers is expressed as;
2(x+1) = 2x+2.
9 less than three times the lesser integer is expressed as;
3x - 9
Equate both expression
2x+2 = 3x - 9
2x-3x = -9-2
-x = -11.
x = 11
The greater integer = x+1 = 11+1 = 12
Hence the integers are 11 and 12
Answer:
11 and 12
