In this diagram, ABAC – AEDF. If the area of ABAC = 24 in2, what is the area of AEDF? D À E 2 in F В 4 in С Area AEDF = [?] in2 please I need help
Answers
Answer: 6
Step-by-step explanation:
The area of the triangle EDF is 6 in².
What are similar triangles?Two triangles are said to be similar if their corresponding angles are congruent, and their corresponding sides are in equal ratios.
Given that, two triangles are similar, ABC and EDF,
We know that, the area of two similar triangles implies that if two triangles are similar to each other, the ratio of their areas will be proportional to the square of their corresponding side ratios.
Therefore,
ar(ΔABC)/ar(ΔEDF) = (2/4)²
24/ar(ΔEDF) = 1/4
ar(ΔEDF) = 6
Hence, the area of the triangle EDF is 6 in².

Billy has $16.30 in dimes and quarters. If he has a total of 88 coins, how many of each type of coin does he have?
Answers
Answer:
38 dimes, 50 quarters
Step-by-step explanation:
Let d = dimes
Let q = quarters
d + q = 88
d = 88 - q
0.10d + 0.25q = 16.30
0.10d + 0.25q = 16.30
0.10(88 - q) + 0.25q = 16.30
8.8 - 0.10q + 0.25q = 16.30
8.8 + 0.15q = 16.30
0.15q = 7.5
q = 50
d = 88 - q
d = 88 - 50
d = 38

53, 13, 34, 41, 26, 61, 34, 13, 69 4) Mean : Median Mode : Range:
Answers
Answer:
Mean: 34.8
median:34
Mode: 13,34
Range:65
Step-by-step explanation:
The value of Mean is 34.4
The value of Median is 34 (middle term)
The value of Mode is 13 and 34.
The value of Range is 56.
Here,
The data set is,
53, 13, 34, 41, 26, 61, 34, 13, 69
We have to find the value of Mean , Median , Mode and Range.
What is Range of the data set?
To find Range of the data set we have to find the difference of highest and lowest number of the set.
Now,
The data set is,
53, 13, 34, 41, 26, 61, 34, 13, 69
Firstly we arranged in the ascending order we get;
13, 13, 26, 34, 34, 41, 53, 61, 69
The Mean of data set is calculated as;
Mean = [tex]\frac{13+13+ 26+ 34+ 34+41+ 53+61+ 69}{9} = \frac{310}{9} = 34.4[/tex]
Hence, The value of Mean is 34.4
And, The Median is calculated as,
There are nine numbers (odd) in the data set, so the median is the middle value of given data set after arranging in ascending order.
Hence, The value of Median = 34 (middle term)
Now, The Mode is the number that appears most often within a data set.
In the data set,
13, 13, 26, 34, 34, 41, 53, 61, 69
Number 13 and 34 repeat two times.
So, The value of Mode = 13 and 34
Now, To find Range of the data set we have to find the difference of highest and lowest number of the set.
Here, In the data set;
The highest number = 69
The lowest number = 13
Hence, Range = 69 - 13 = 56
Therefore,
The value of Mean is 34.4
The value of Median is 34 (middle term)
The value of Mode is 13 and 34
The value of Range is 56
