When we rotate clockwise or counterclockwise, the two rotations should always add up to _________ degrees
Two counter-clockwise or clockwise rotations of 90° should become 180°
If you add a counter-clockwise and clockwise rotation of 90° together they will cancel out to 0°
If you add full rotations of either in any amount it will always be 0°
Answer:
Two counter-clockwise or clockwise rotations should become 180°
If you add a counter-clockwise and clockwise rotation together they will cancel out to 0°
Step-by-step explanation:
Use the conversions given below to change 153 cm into feet.
Give your answer rounded to 1 dp.
1 inch = 2.54 cm
1 foot = 12 inches
Dont give ridicuous pls
Answer:
4 feet, 5.1 inches
Step-by-step explanation:
Answer:
Step-by-step explanation:
1 inch = 2.54 cm
x = 153 cm
1/x = 2.54/153 Cross Multiply
2.54x = 153 Divide by 2.54
x = 153/2.54
x = 60.236 inches.
12 inch = 1 foot
60.236 inches = x
12/60.236 = 1/x
12x = 60.236
x = 60.236/12
x = 5.02 feet
To one decimal point this is 5.0 feet.
A movie theater has 24 screens. The ratio of action films to other films currently showing on all of the screens 1:2. How many action films are currently showing?
Answer:
8:16, 8 actions films
Step-by-step explanation:
1:2 = 1x:2x
= 24 / (1x+2x)
= 24 / 3x = 8, x = 8
= 8*1 : 8*2
= 8:16
Proof:
8 + 16 = 24

The Lake Smith basketball team had a team picture taken of the players, the coaches, and the trophies from the season. The picture was 4 inches by 6 inches. The team decided to have the picture enlarged to a poster and then enlarged again to a banner measuring 48 inches by 72 inches.
If the scale factor from the picture to the poster is 500%, find the dimensions of the poster.
What scale factor, as a percent, is used to create the banner from the picture?
What percent of the area of the picture is the area of the poster?
Assume you started with the banner and wanted to reduce it to the size of the poster.
What would the scale factor as a percent be?
9514 1404 393
Answer:
poster dimensions: 20 inches by 30 inchesbanner/picture scale factor: 1200%poster/picture area ratio: 2500%poster/banner reduction ratio: 41.67%Step-by-step explanation:
a) Poster dimensions are 500% of the picture dimensions:
500% · 4 in = 500/100 · 4 in = 5 · 4 in = 20 in
5 · 6 in = 30 in
The poster is 40 in by 30 in.
__
b) The ratio of banner sized to picture size can be found from the ratio of the smaller dimensions:
48 in/(4 in) = 12 = 12 · 100% = 1200%
__
c) The poster/picture area ratio is the square of the scale factor:
poster area/picture area = (500%)^2 = (500/100)^2 = 25
= 25 · 100% = 2500%
__
d) The poster/banner reduction ratio is ...
20 in/48 in = 5/12 ≈ 0.4167 = 0.4167 · 100% = 41.67%
_____
Additional comment
To convert a number or fraction to a percentage, multiply by 100%. To convert a percentage to a number, divide by 100%, or recognize that "%" means "/100". (As above, 500% = 500/100 = 5.)
Which statement correctly describes the expression (-12)(-20)?
A. Both factors are negative, so the product will be negative.
B. One factor is positive and one factor is negative, so the product will be negative.
C. One factor is positive and one factor is negative, so the product will be positive.
D. Both factors are negative, so the product will be positive.
Answer:
D.
Step-by-step explanation:
If both factors are negative, it will make a positive.
If one factor is negative, and the other is positive, it will make a negative.
If both factors are positive, it will make a positive.
Answer: The answer is D. Both factors are negative, so the product will be positive and the answer is 240

What can be concluded about the line represented in the table? Check all that apply.
The slope is 2.
The slope is 1/2
The y-intercept is -4.
The y-intercept is 8.
The points (-2,-5) and (8,0) are also on the line.
The points (-5,-2) and (1,10) are also on the line
Answer: y=mx+b, m=(y2-y1)/(x2-x1), b=y-intercept, value of y when x=0
m=(-8-10)/(-2-1)
m=-18/-3
m=6
y=6x+b, using (1, 10) we can solve for b
10=6(1)+b
10=6+b
4=b so the line is:
y=6x+4

James says that 12 is a common factor of 3 and 4. June says that 12 is a common multiple of 3 and 4. Who is correct? Defend your answer and explain your reasoning
Answer:
June is correct.
Step-by-step explanation:
A common factor means that 4 and 3 could be divided by 12. A common multiple means that 3 and 4 multiplied together equal 12.
Which equation is correctly rewritten to solve for y?
12y + d = –19y + t
A. Y= t+d/-7
B. Y= -7(t+d)
C. Y= t-d/31
D. Y= 31(t-d)
Answer:
C. y=(t-d)/31
Step-by-step explanation:
Step 1: Add 19y to both sides.
31y+d=t
Step 2: Add -d to both sides.
31y=t-d
Step 3: Divide both sides by 31.
y=(t-d)/31

Nina saved money in her piggy bank to buy a music player she started by saving 30$ that she received for her birthday and then she saved 10$ from her allowance each month for 6 months. The table below shows the total amount of money Nina had save at the end of each month for 6 months .
Answer:
No, it does not represent a proportional relationship.
Step-by-step explanation:
The ratios do not reduce to the same value.
40/1 = 40
50/2 = 25
60/3 = 20
We can also tell straight away that this is not a proportional relationship because Nina starts with $30. If the data were graphed, this would mean that the line would not go through the origin. It would start at 30 on the y axis.
