On a electricity bill of $14.80, mrs.miller pays only $38.76 because she pays a certain date. what percent discount is mrs.miller allowed?
Answers
Answer:
I assumed that you made a mostake and meant:
On a electricity bill of $38.76, mrs.miller pays only $14.80 because she pays a certain date. what percent discount is mrs.miller allowed?
62% approx
Step-by-step explanation:
$38.76 - $14.80 = $23.96
23.96/38.76 = 61.8%
Mrs. Miller is allowed a discount of approximately 5% on her electricity bill.
To calculate the percent discount that Mrs. Miller is allowed on her electricity bill, we can use the following formula:
Percent discount = (Discount amount / Original amount) * 100
In this case, the original amount of the bill is $40.80, and Mrs. Miller pays only $38.76, which means she receives a discount of $40.80 - $38.76 = $2.04.
Now, let's calculate the percent discount:
Percent discount = ($2.04 / $40.80) * 100 ≈ 5%
The discount is given as a percentage of the original bill amount and represents the amount saved by Mrs. Miller due to paying on a certain date or any other special offer provided by the electricity company. By paying $38.76 instead of $40.80, she saves $2.04, which is 5% of the original bill.

All digits in a dropdown number are different, and one of its digits is the average of all its digits. It has at least two digits. For example, 5021 is a dropdown number, but neither 4389 nor 6033 is a dropdown number.
Questions:
1. Find the smallest dropdown number.
2. What are the smallest and largest 4-digit dropdown numbers?
3. How many 3-digit dropdown numbers are there?
4. Is it possible for a pair of consecutive numbers to both be dropdown numbers? If not, explain why not. If it is possible, find the smallest such pair.
Answers
1. Start the search among 2-digit numbers. A dropdown number (DDN) with 2 digits is a number [tex]ab[/tex] such that
[tex]\dfrac{a+b}2 = a \implies a + b = 2a \implies b = a[/tex]
or
[tex]\dfrac{a+b}2 = b \implies a+b = 2b \implies a=b[/tex]
but both of these solutions violate the requirement that the digits are distinct, so there are no 2-digit DDNs.
A 3-digit DDN [tex]abc[/tex] is such that
[tex]\dfrac{a+b+c}3 = a \implies a+b+c = 3a \implies b+c = 2a[/tex]
or [tex]a+c=2b[/tex] if the average is [tex]b[/tex], or [tex]a+b=2c[/tex] if the average is [tex]c[/tex]. The smallest possible value for [tex]a[/tex] is 1 since we require 3 digits. Then [tex]b+c=2[/tex], and we can pick [tex]b=0[/tex] and [tex]c=2[/tex] to get the smallest DDN, 102.
2. In a 4-digit DDN [tex]abcd[/tex], we have
[tex]\dfrac{a+b+c+d}4 = a \implies a + b + c + d = 4a \implies b+c+d=3a[/tex]
or [tex]a+c+d=3b[/tex] or [tex]a+b+d=3c[/tex] or [tex]a+b+c=3d[/tex].
We're free to fix [tex]a=1[/tex] and [tex]b=0[/tex] to try to get the smallest DDN. This leaves us with [tex]c+d=3[/tex] or [tex]c+d=-1[/tex] or [tex]1+d=3c[/tex] or [tex]c=3d[/tex].
The first two cases are impossible - the only choices for [tex]c,d[/tex] such that [tex]c+d=3[/tex] are 1 and 2, and the sum of two positive integers must be positive. The smallest possible value of [tex]c[/tex] is 2; this leaves us with [tex]1+d=6[/tex] or [tex]2=3d[/tex], but the latter case is impossible because 3 does not divide 2. So [tex]d=5[/tex], and the smallest 4-digit DDN is 1025.
To find the largest DDN, start with the largest possible values for [tex]a[/tex] and [tex]b[/tex]. Let [tex]a=9[/tex] and [tex]b=8[/tex]. Then [tex]c+d=19[/tex] or [tex]c+d=15[/tex] or [tex]17+d=3c[/tex] or [tex]17+c=3d[/tex]. At most, we can have [tex]c+d=13[/tex] with 7 and 6, so the first two cases are impossible. If we maximize [tex]c=7[/tex], then either [tex]17+d=21\implies d=4[/tex] or [tex]24=3d\implies d=8[/tex] (which we don't want). So the largest 3-digit DDN is 9874.
3. I don't have an analytical solution to this, but using brute force (program) the total count is 112.
4. It is possible; consider 1249 and 1250, with digital averages
[tex]\dfrac{1+2+4+9}4=4 \text{ and } \dfrac{1+2+5+0}4=2[/tex]
which happens to be the smallest pair. (Also found with brute force.)

From one of the congruent triangles theorem, we have that
If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
This is the SAS (Side-angle-side) theorem.
From the given information,
AB and CD intersect at point O
Thus, AO = BO
Also,
∠ACO ≅ ∠BDO
In the diagram, we can as well observe that CO ≅ DO
Thus, we can conclude that AC ≅ BD
Since sides AC, CO and the included angle ACO are congruent to sides BD, DO and the included angle BDO, we can conclude that ΔACO ≅ ΔBDO using the SAS theorem.
Hence, we have proven that ΔACO ≅ ΔBDO

Step-by-step explanation:
Since 5 and 6 are coprime, the least common multiple is their product, which is 30.
Answer: 30
Step-by-step explanation:
The least common multiple of two numbers, or LCM, is the smallest multiple that can divide evenly into both numbers. We can easily find the LCM by finding the primes that multiply into both numbers.
[tex]5=5\\ 6=2*3[/tex]
If there were any in common between the factorization of both numbers, we would only need to count it once. Since there weren't any, the smallest multiple of both numbers would be their product, 30.
Hence, the LCM of 5 and 6 is 30.

24c = 13.44
c = 0.56.
so each cookie costs 56 cents
Answer:
13.44 to make 1 batch. 0.56 to make 1 cookie.
Step-by-step explanation:
If it cost 134.40 to make 10 batches, then you would divide that by 10 for how much it cost for 1 batch.
Then, 1 batch of 24 costs 13.44, you would divide it by 24 for the cost of 1 cookie.
