I can't write out the whole proof here.
it bisects, so we know BCA is congruent to DCA
abc being congruent to adc is given
AC = AC because it is a singular side

then the lines are congruent by CPCTC
Write a paragraph explaining why consumer goods packaged in cube-shaped boxes would use less packaging material than rectangular boxes containing the same product volumes. Provide an example, including sketches of the boxes and their dimensions, to substantiate your explanation. Why aren’t more products in cube-shaped boxes?
Answer:
Students review how to determine the surface area and volume of a rectangular prism, that all dimensions are equal in cubes so the volume of cubes are the length of any side raised to the third power, or cubed. This prepares them for two associated activities. First, students find the volumes and surface areas of rectangular boxes such as cereal boxes and then figure out how to convert their boxes into a new, cubical boxes having the same volume as the original. As they construct the new, cube-shaped boxes from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package items. Students consider why consumer goods are generally not packaged in cube-shaped boxes, even though this would require fewer materials and ultimately, less waste. Then, to display their findings, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved.

Larry's math teacher did not want to announce her age. She told her students if
they could solve the riddle, it would reveal how old she was. Her riddle stated: "The
product of my age and five, then decreased by twenty and finally increased by my
age times negative three is fifty." How old was Larry's math teacher? Hint: Write the
equation first, then solve to find the missing part.
Answer:
age is 35
Step-by-step explanation:
5a - 20 + (-3a) = 50
2a - 20 = 50
2a = 70
a = 35

Need help with this trigonometry word problem
From the top of the tower 30 m height a man is observing the base of a tree at an angle of depression measuring 30 degree. Find the distance between the tree and the tower.
Please show your work
Answer:
30√3 m ≈ 52 m
Step-by-step explanation:
The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. The long leg of the triangle is √3 times 30 m, or about 51.96 m.
The distance between the tree and the tower is about 30√3 m ≈ 52 m.
__
If you haven't memorized the ratios of this special triangle, you can use the relation ...
Tan = Opposite/Adjacent
tan(30°) = 30/d
d = 30/tan(30°) = 30√3 = 51.96 . . . . same as above

Answer:
D
Step-by-step explanation:
Just took the quiz. Hope it helped
Answer is Option - D
Scale Factor is defined as the ratio of the size of the new image to the size of the old image.
If the scale factor is more than 1, then the image stretches.
If the scale factor is between 0 and 1, then the image shrinks.
If the scale factor is 1, then the original image and the image produced are congruent.
The only change in the dilation process is that the distance between the points changes. It means that the length of the sides of the original image and the dilated image may vary.
Here,
By dilation with factor 2 to the small triangle, its sides becomes equal as big triangle.
Now, center the small triangle at origin(0,0).
Then, transform the small triangle to (x + 6, y) i.e., it exactly gets the coordinates of the big triangle.
There are same in terms of sides length and coordinates.

Draw a conclusion is the statment below always, sometimes, or never true ? Bive at least two examples to support your reasoning. The lcm of two numbers is the product of the two number discuss your conclusion with a partner
Answer:
Sometimes
Step-by-step explanation:
Example 1:
Take two numbers as [tex]7,8[/tex]
LCM of [tex]7,8=7(8)=56[/tex]
In this case, the lcm of two numbers is equal to the product of the two numbers.
Example 2:
Take two numbers as [tex]6,3[/tex]
[tex]6=3(2)[/tex]
So,
LCM of [tex]6,3=3(2)=6[/tex]
In this case, the lcm of two numbers is not equal to the product of the two numbers.
Therefore,
Sometimes, the lcm of two numbers is equal to the product of the two numbers.

Paige and Cindy have been saving money. Paige started with $350 in her savings and deposits $25 into her savings each week. Cindy's savings is represented by the equation T = 190 + 40w, where T is total savings and w is the number of weeks. In how many weeks will Cindy have more money in her savings than Paige? A. 10 B. 12 C. 13 D. 11
Answer:
D. 11
Step-by-step explanation:
T = total savings
w = number of weeks
Paige:
T = 350 + 25w
Cindy:
T = 190 + 40w
In how many weeks will Cindy have more money in her savings than Paige
Equate the total savings of both of them
350 + 25w = 190 + 40w
Collect like terms
350 - 190 = 40w - 25w
160 = 15w
w = 160/15
w = 10.67
Approximately,
In 11 weeks, will Cindy have more money in her savings than Paige
Check:
Paige:
T = 350 + 25w
= 350 + 25(11)
= 350 + 275
= 625
Cindy:
T = 190 + 40w
= 190 + 40(11)
= 190 + 440
= 630

Mail order a mail order company has a 10% success rate. If it mails advertisements to 602 people, find the probability of getting less than 57 sales. Round z value calculations to 2 decimal places and final answer to at least 4 decimal points
Answer:
0.30854
Step-by-step explanation:
Given :
Sample size, n = 602
p = 10% = 0.1
q = 1 - p = 1 - 0.1 = 0.9
Using binomial approximation :
Mean, m = n * p = 602 * 0.1 = 60.2
Standard deviation, s = sqrt(npq) = sqrt(602*0.1*0.9) = 7.36
P(x < x - 0.5) = (x - m) / s
x = 57
P(x < 56.5) = (56.5 - 60.2) / 7.36
Z = - 3.7 / 7.36
Z = - 0.5027 = - 0.50
P(Z < - 0.50) = 0.30854 (Z probability calculator)
