A kitchen wall tile is shaped like a parallelogram. The base of the tile is two times the height of the tile. The height of the tile is 2 in. The length of the other side of the tile is 3 in. What is the area of the tile?
Answer:
Area = 10 in
Step-by-step explanation:
Base=4 in , Height=2 in , Other Side = 3 in.
Height x Other Side + Base
2 x 3 + 4
2 x 3 = 6 + 4 = 10

measures of the angles.
Step-by-step explanation:
Since they are complementry angles :
(12x-9) + (8x + 14) = 90°
20x + 5 = 90°
X = 4.25 °
Angles are 42° and 48°.

At 8 a.m. the temperature was 56°F. By noon a storm had arrived, and the temperature was 43°F. Which describes the change in the temperature from 8 a.m. until noon?
Answer:
13°F
Step-by-step explanation:
Given that,
Initial temperature = 56°F
Final temperature, = 56°F
We need to find the change in temperature. It is equal to the difference between final temperature and the initial temperature. So,
[tex]\Delta T=T_f-T_i\\\\\Delta T=43^{\circ}F-56^{\circ} F\\\\\Delta T = 13^{\circ} F[/tex]
So, the change in temperature is 13°F.
Answer:
13°F

1. Ilove ordering cookies from Tiff's Treats (not
sponsored, although I wouldn't object!). If Tiff's
Treats charges a delivery fee of $1 and costs $8.50
per half-dozen, which equation relates my cost, c,
and the number of half-dozens, h, I ordered?
a) C = 9.500h
b) C = 8.50h + 1
c) c = h + 8.50
d) h = 9.50c
e) None of these
c = cost
h = # of half-dozens ordered
c = $8.50h + $1 is the correct answer.
L varies directly with the square of Z. L is 12 when Z is 2. Find the value of L when Z is 4.
Answer:
L = 48
Step-by-step explanation:
Given that L varies directly with Z² , then the equation relating them is
L = kZ² ← k is the constant of variation
To find k use the condition L = 12 when Z = 2 , then
12 = k × 2² = 4k ( divide both sides by 4 )
3 = k
L = 3Z² ← equation of variation
When Z = 4 , then
L = 3 × 4² = 3 × 16 = 48

Step-by-step explanation:

Answer:
[tex]\boxed {\tt m=1}[/tex]
Step-by-step explanation:
The slope formula is:
[tex]m= \frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are points on the line.
Let's pick two points from the graph : (1,2) and (4,5). Match the variables and numbers, so:
[tex]x_1=1\\y_1=2\\x_2=4 \\y_2=5[/tex]
Substitute the values into the formula.
[tex]m=\frac{5-2}{4-1}[/tex]
Solve the numerator. Subtract 2 from 5.
[tex]m=\frac{3}{4-1}[/tex]
Solve the denominator. Subtract 1 from 4.
[tex]m=\frac{3}{3}[/tex]
Divide 3 by 3.
[tex]m=1[/tex]
The slope of the line is 1.

Determine which of the following statements about rigid transformations is false.
Question 5 options:
In a translation, the segments joining points of the pre-image and their images are perpendicular.
In a reflection, the segments joining points of the pre-image and their images are perpendicular to the line of reflection.
In a rotation, the points of the pre-image are always the same distance away from the center of rotation as the corresponding points of the image.
In a reflection, the points of the pre-image are always the same distance away from the line of reflection as the corresponding points of the image.
Answer:
The false statement about rigid transformation is;
In a translation, the segments joining points of the pre-image and their images are perpendicular
Step-by-step explanation:
The direction of a rigid transformation involving a translation can vary from changes in the values of one of the two coordinates of the vertex points in the figure with the same change value for all the vertices or
The translation can also be made by changing the values of both coordinates of the vertex each coordinate having equal value of change which may be different from the value of change of the other coordinate, maintaining the size of the figure.
In the second case, the translation can be in other directions other than vertical or horizontal, such that, the segments joining the points of the pre-image with the corresponding point on the image are parallel.
The false statement about rigid transformation is;
In a translation, the segments joining points of the pre-image and their images are perpendicular
The direction of rigid transformation:It includes a translation that could be varied from changes in the values of one of the two coordinates of the vertex points having the same change value for all the vertices. The translation could also be made via changing the values of both coordinates of the vertex every coordinate that contains the equal value of change.

Karen owns a seafood restaurant. She orders trout from an online retailer.
Each pound of trout costs $30, and the company charges a $2 fee for
shipping the order. However, if Karen orders 10 or more pounds, the trout
costs only $24 per pound, but the shipping fee is $6.
Which piecewise function models the cost of x pounds of trout?
A. f(x) =
30x + 2, 0 < x < 10
24x + 6, 2 > 10

24x + 6, 3 > 10
D. f(x) =

30x + 2, 3 > 10

Answer: 30x+2, 0<x<10
24x+6, x>10
Step-by-step explanation:
Make sure the x>6 has the line under the >. It would not let me enter it like that.
The piecewise function that models the cost of x pounds of trout is: [tex]\bold{f(x)=\left \{ {{30x + 2,~~0 < x < 10} \atop {24x + 6,~~~x > 10}} \right. }[/tex],
What is piecewise function?"It is a function that is defined on a sequence of intervals."
For given question,
'x' represents number of pound of trout.
Each pound of trout costs $30, and the company charges a $2 fee for
shipping the order.
We write this in equation form as,
f(x) = 30x + 2
This is possible if Karen orders less than 10 pounds.
So, the function would be,
f(x) = 30x + 2, 0 < x < 10
If Karen orders 10 or more pounds, the trout costs only $24 per pound, but the shipping fee is $6.
This means, the function would be,
f(x) = 24x + 6, x > 10
Hence, the piecewise function that models the cost of x pounds of trout is: [tex]\bold{f(x)=\left \{ {{30x + 2,~~0 < x < 10} \atop {24x + 6,~~~x > 10}} \right. }[/tex]

it is not repeating or terminating which means it is irrational
The given number 0.737337333733337333337... non-repeating and non-terminating so it will be an irrational number.
What is an irrational number?Any real number that cannot be written as the quotient of two integers, p/q, where p and q are both integers, is referred to as an irrational number.
In another word, irrational numbers are those numbers that can not terminate.
For example, √2, and √3 are irrational numbers because they cannot be written as p/q where p and q both should be integers.
Given the decimal 0.737337333733337333337... it not repeating and nonterminating so we cannot convert it into the fraction p/q such that p and q both remain integers.

• 8.1 ft &
8.6 ft
© 8.9 ft
Answer:
8.66 ft
Step-by-step explanation:
A square is a shape that has an equivalent length and breadth across it’s cross section.
What this means is that measuring the length across the top and bottom will yield the same length value.
Thus, mathematically, let’s call the measured height h
The square of this height gives the area
thus;
h^2 = 75
h = √75
h = 8.660254037844
This is approximately 8.7 to one decimal place
