tan A = \(\frac{opposite}{adjacent}\) = \(\frac{BC}{AB}\) = \(\frac{2}{4}\) = \(\frac{1}{2}\)
tan C = \(\frac{AB}{BC}\) = \(\frac{4}{2}\) = 2

Answer:
2 in²
Step-by-step explanation:
1 in²/25 mi² = x in ²/ 50 mi²
25 * x = 50
x= 50/25
x= 2
therefore, The area of the wildlife refuge is [2in²] square inches on the map.
1in/25mi= x/50
Since 25 is half of 50 we can assume that 1 is half of x.
Knowing this we can add 1+1 (Easy math here!) to get 2

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 15) = 15. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 15 = 75. In the following intermediate step, cancel by a common factor of 15 gives 1/1.
In other words - four fifths plus three fifteenths = one.
Subtract: the result of step No. 1 - 2/
3 = 1 - 2/3= 1/1- 2/3 = 1 · 3/1 · 3 - 2/3 = 3/3 - 2/3 = 3 - 2/3 = 1/3

Answer:125 yen
Step-by-step explanation:
Ratio and proportion
Ratio=1:80=x:10,000
x represents dollars which is unknown
1/80=x/10,000
Then you cross multiply
80x=10,000
80x/80=10,000/80
x=125
Therefore,$125 will give you 10,000yen

Answer:
x = 7.5, y = 8.5-----------------------------------
The two angles with the variable x form a linear pair and therefore:
16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5Angles 16x - 18 and 12y are congruent as vertical angles:
16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5Answer:
x = 7.5
y = 8.5
Step-by-step explanation:
Linear Pair
Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).
To find x, equate the sum of the two angles with the variable x to 180° and solve:
⇒ (16x - 18)° + (10x + 3)° = 180°
⇒ 16x - 18 + 10x + 3 = 180
⇒ 26x - 15 = 180
⇒ 26x = 195
⇒ x = 7.5
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Therefore:
⇒ (16x - 18)° = 12y°
Substitute the found value of x into the equation and solve for y:
⇒ 16x - 18 = 12y
⇒ 16(7.5) - 18 = 12y
⇒ 120 - 18 = 12y
⇒ 102 = 12y
⇒ y = 8.5

show that the (5,5),(5,0),and (0,0) are the vertices of an isosceles triangle.
Answers
An isosceles triangle has 2 sides that are equal.
I plotted these points. See attached screenshot.
The first side's distance is 5. You can just count those units along the x axis. (0,0) and (5,0) share the same y coordinate, so the difference in x coordinates is 5-0 = 5.
The next sides's distance is also 5. You can count that distance on the coordinate plane. (5,5) and (5,0) share the same x coordinate, so the difference in y coordinates is 5-0 = 5.
These two sides make a right triangle and are equal length. This is an isosceles right triangle.

Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.
Answers
Answer:
Beth's class left for the field trip at 7:13 A.M..
Step-by-step explanation:
To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.
The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.
To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.
9:41 A.M. minus 55 minutes is 8:46 A.M..
8:46 A.M. minus 93 minutes is 7:13 A.M..
Therefore, Beth's class left for the field trip at 7:13 A.M..
I hope that helps!
Answer:

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.
