Answer:
C. ASA postulateStep-by-step explanation:
We observe two angles and the included side of ABC are congruent to two angles and the included side of DBE:
∠A ≅ ∠D∠C ≅ ∠ EAC ≅ DEThis is called ASA
Answer:
ASA postulate
Answer C is correct
Step-by-step explanation:
<ACB = < BED (Angle)
AC = DE (Side)
<CAB = < BED = 90° (Angle)
Therefore,
ABC triangle is congruent to DBE triangle according to ASA postulate.

Don is 6 feet tall. At a given time of day, he measures his shadow to be 10 feet long.
At the same time, he measures the shadow length of a nearby tree to be 38 feet. How
tall is the tree?
Round your answer to the nearest whole foot.
Answers
Answer:
Ok, so with this problem, you would start with the equation 6/10=x/38.
Then, cross multiply:
38(6)=10x
After, you would:
38 x 6 = 228
Then:
228/10
Lastly:
x=22.8m which when rounded equals 23 ft.

The y-intercept is the value of the function when x=0. It is where the graph crosses the y-axis.
f(0) = a·b^0 = a·1 = a
Reading the y-intercept from the graph, we see ...
The y-intercept is 3. The a-value of the function is 3.
__
The point when x=1 is ...
f(1) = a·b^1 = 3b
Reading the value from the graph, we find the point to be (1, 6). This means ...
3b = 6
b = 2 . . . . . . . divide both sides by 3
The point when x=1 is (1, 6). The b-value of the function is 2.
The equation of the function is f(x) = 3·2^x.

oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. what was the total average speed
Answers
90 miles + 120 miles = 210 total miles
1.5 hours + 3 hours = 4.5 total hours.
Average speed = total distance / total time
Average speed = 210 miles / 4.5 hours = 46 2/3 miles per hour
The total average speed for Oliver is 42 miles per hour
Given the following data:
Distance A = 90 milesDistance B = 120 milesTime A = 1.5 hoursTime B = 3 hoursTo find the total average speed:
First of all, we would determine the total distance and total speed:
[tex]Total \; distance = Distance\;A + Distance\;B\\\\Total \; distance = 90+120\\\\Total \; distance = 210\;miles[/tex]
[tex]Total \; time = Time\;A + Time\;B\\\\Total \; distance = 1.5+3\\\\Total \; distance = 4.5\;hours[/tex]
Mathematically, the average speed is given by the formula:
[tex]Average\;speed = \frac{Total\;distance}{Total\;time}[/tex]
Substituting the parameters into the formula, we have;
[tex]Average\;speed = \frac{210}{4.5}[/tex]
Average speed = 42 miles per hour.

Michael bought 8 new Pokemon cards to add to his collection.
The next day his dog ate half of his collection. There are now only
40 cards left. How many cards did Michael start with?
Answers
Answer:
72
Step-by-step explanation:
I like to work backward with problems like these. I'll start out with 40. Then it says that his dog ate half of this number. Instead of dividing by 2, I'll have to multiply by two since I'm working backward.
So, now I have 80, the number of cards he had before his dog ate half of the collection. We also see that he bought 8 new Pokemon cards and added these two his collection. Instead of adding 8, I'll subtract 8 from 80, giving me 72. So, this is his original amount.
If I take this number and go back through the scenario, I can check my work.
72 + 8 = 80, 80/2 = 40

"Find the measures of two supplementary angles if their measures are 3:7
Since the ratio is 3:7 we can assume that the angles are equal to 3x and 7x?"
3x+7x=180° (180° since a line is equal to that)
then solve
10x=180
x=18
then substitute x=18 in 3x and 7x
3x=54°. 4x=126°
126° and 54°
Answers
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126
Answer:
The two angles are 54 degrees and 126 degrees.
