Answer:
1 dozen = 12 units
7 dozen = 12 × 7 = 84 units
Correct unit price = 103.32 ÷ 84 = $1.23
The contractor's unit price incorrect because he did 103.32 ÷ 7 dozen.
The price he calculated is for the price for 1 dozen, not 1 unit

the length of a side of a rectangle is 6 cm. what should the length of the other side be so that the perimeter of the rectangle is smaller than the perimeter of a square with a side of 4cm?
Answer:
1cm
Step-by-step explanation:
A square with a side of 4cm will have a perimeter of 16cm (4+4+4+4).
If you put 2 on the other side of the rectangle, the perimeter will be: 6+1+6+1=14cm, which is smaller than the square's perimeter.
A mustard seed has a mass of about 0.002 gram. A glass jar contains about 4.3602 x 10^4 A B C or D
Answer:
(2 x 10 ^-3) x (4 x 10 ^4)=8 x 10 ^1
Step-by-step explanation:
The mass of a single seed can be written as 0.002 = [tex]2*10^{-3}[/tex]
There are total of 4.3602 * 10 ⁴seeds in the jar
Total mass is the multiplication of these both numbers.
Since we want an estimate, we can use 4 instead of 4.3602 in the 2nd number.
The rule to multiply two numbers in scientific notation is:
[tex](a*10^{b} )*(c*10^{d} )=(a*c)*10^{b+d}[/tex]
So using this formula we multiply the 2 numbers and get answer as follows:
[tex](a*10^{b} )*(c*10^{d} )=(a*c)*10^{b+d} \\(2*10^{-3} )*(4*10^{4} )=(2*4)*10^{-3+4} \\=8*10^{1}[/tex]

Step-by-step explanation:
Explanation:
Relation I has each item in the domain map to exactly one item in the range. So any input leads to exactly one output. Therefore, we have a function here.
In contrast, relation II has the input x = 0 lead to multiple outputs (namely y = 8 and y = -1 at the same time). This indicates we do not have a function here.
Relation III is the same as as the previous one. This time the input x = -2 maps to both y = 1 and y = -7 at the same time. We don't have a function here either.
If you wanted, you can plot these points on the xy plane to see that relations II and III fail the vertical line test. You would need to plot each relation separately.

Answer:
Step-by-step explanation:
X=16x
z=116
16x+112=128
360-128=232
232 divide by 2=116
Answer:
x = 9
z = 68
Step-by-step explanation:
For x, the top and bottom angles have the same value. To get x, you need to set up this equation: 12x + 4 = 112. Subtract 4 from itself and from 112. Your equation will then be 12x = 108. Divide 108 by 12, and then your answer is 9. So the value of x is 9.
For z, it's supplementary with the top angle. This means that the two angles combined add up to 180. So your question is: 112 + z = 180. Subtract 112 from 180, and then your answer is 68. So the value of z is 68.

[tex]\frac{x}{100}(60)=24[/tex] [tex]\frac{60}{100}x= 24[/tex] [tex]\frac{3}{5}x=24[/tex]Step 3: Multiply both sides by 5/3.
[tex]\frac{3}{5}x* \frac{5}{3}=24 * \frac{5}{3}[/tex] [tex]x = \frac{120}{3}[/tex] [tex]x = 40[/tex]Therefore, the missing number is 40 to make 40% of 60 = 24.

Statement 3 ) 9x - 54 = 34
Reason 4 ) Addition Property of Equality
Reason 5 ) Division Property of Equality
Step-by-step explanation:
Let's me know if it wrong.
The missing statement and reason for the proof that the solution of 9(x - 6) + 41 = 75 is x = 88/9 are:
S3: 9x - 54 = 34
R1: Given
R2: Subtraction property of equality
R3: Distributive property
R4: Subtraction property of equality
R5: Division property of equality
The given equation is:
Statement1: 9(x - 6) + 41 = 75
Reason 1: Given
Collect like terms
9(x - 6) = 75 - 41
Statement 2: 9(x - 6) = 34
Reason 2: Subtraction property of equality
Expand the equation using distributive rule
Statement 3: 9x - 54 = 34
Reason 3: Distributive property
Collect like terms in the equation 9x - 54 = 34
9x = 34 + 54
Statement 4: 9x = 88
Reason 4: Subtraction property of equality
Divide both sides by 9 in the equation 9x = 88
Statement 5: x = 88/9
Reason 5: Division property of equality

A drinking glass is in the shape of a cylinder. The volume of the glass is 2211.68 cubic centimeters, and its diameter is 16 centimeters. Find the height of the glass.
Round the answer to the nearest centimeter. Include the units in your typed answer.
Answer:
11cm
Step-by-step explanation:
diameter = 16, r = 8 (16÷2)
π = 3.142
V=πr2h
2211.68 = π x 8^2 x h
2211.68 = 3.142 x 64 x h
2211.68 ÷ 64 ÷ 3.142 = h
h = 10.9986
= 11 cm (round off to nearest cm)
To check and confirm
V=πr2h
3.142 x 64 (8^2) x 10. 9986 = 2211.68
y ∝ 1 √ x If y = 7 when x = 36 find, y when x = 4
Help please
Answer:
Yo Rick Astley
Step-by-step explanation:
y ∝ 1 √ x
y = k (1 √ x)
y = 7 when x = 36
7 = k ( 1 / √36)
7 = k (1/6)
k= 7 × 6
k = 42
If x = 4 then,
y = 42 ( 1/√4)
y = 42 ( 1/2)
y= 21

A line has a slope of 1/2 and contains the points (3, y) and (5,7). The value of y is.
Answer:
The value is 6
Step-by-step explanation:
Since the slope is 1/2, you can plot the coordinates 5,7.
5=x axis
7=y axis
After that you can use the formula rise/run = 1/2
Then you plot 3 on the graph. Then you use formula rise over run,
then you get 6

E. Reflection across the perependicular bisector of segment AB
F. Translation by the directed line segment AB
G. Translation by the directed line segment BA
The given transformation of reflection, rotation and translation are rigid transformation
The transformation that must take any point A to any point B are;
Rotation of 180° around the midpoint of segment ABReflection across the perpendicular bisectorTranslation by the directed line segment ABReason:
Question: The given quadrilaterals ABCD and A'B'C'D' are congruent
Required; To select all transformation that must take a point A to point B
Solution:
Rotation of 180° around the midpoint of segment ABA rotation of 180° about the midpoint of segment AB will change the places of points A and B
A(x, y) → R₁₈₀ → A'(-x, -y)
Let the coordinates of the origin be the midpoint of segment AB, and let (x, y) represent the coordinate of the point B(x, 0) we have;
∴ The coordinates of point A is A(-x, 0), which gives;
A(-x, 0) → R₁₈₀ → A'(x, 0) = point B
Therefore a rotation about the midpoint of AB must take point A to point B
Reflection across the perpendicular bisectorThe reflection of a point (x, y) about y-axis gives a point (-x, y), therefore, we have;
A(-x, 0) → Reflection across the y-axis → A'(x, 0) = point B
Therefore, a reflection across the perpendicular bisector of the line AB must take the point A to point B
Translation by the directed line segment ABA translation along the directed line segment AB of point A(-x, 0) 2·x units right gives;
A'(-x + 2·x, 0) = A'(x, 0) = Point B
Therefore, the transformations that must take any point A to any point B are;
Rotation of 180° around the midpoint of segment AB
Reflection across the perpendicular bisector
Translation by the directed line segment AB
