Angle of taller building Tan 45° = opposite (height of the building)/ adjacent 50 feet (distance between Kathy and the taller building
Tan 45° = 1
Height of taller building from eye level = multiplying adjacent 50 feet * Angle (Tan 45°) 1 = 50 feet opposite
Angle of smaller building Tan 38° = 0.781
Height of smaller building from eye level = Angle * adjacent 50 feet = 39.06 feet
Difference of eye level from ground is 5 feet
Taller building height is 50 + 5
Total height of taller building is 55 feet.
Smaller building height is 39.06 + 5
Total height of smaller building is 44.06 feet
count them
b
count a sample and estimate the number of times it would take to fill using the sample
c
the area of the jar divided by the area of an M&M
d
measure the height of the jar
e
the volume of the jar divided by the volume an M&M
i think its b or e because i rember doing these in school and what i would do is i would look at the jar and one of the thing we had to guess and then i would guess or e because you could look at lenght width and height
There are multiple ways to estimate the number of M&M's in a jar, including counting them, counting a sample, and calculating the volume ratio.
Estimating the number of M&M's in a jar can be done using multiple methods. First, you can count them one by one, which is time-consuming but accurate. Second, you can count a sample of M&M's and estimate the number of times it would take to fill the jar using the sample. Lastly, you can calculate the volume of the jar divided by the volume an M&M to estimate the number of M&M's in the jar.

if inhes
then D
A. Parasailing: $39; Horseback Riding: $48
B. Parasailing: $51; Horseback Riding: $30
C. Parasailing: $27; Horseback Riding: $46
D. Parasailing: $63; Horseback Riding: $24
Answer:
Horseback riding costs $30 and parasailing costs $51, so B.
Step-by-step explanation:
This is answered by using simultaneous equations, let x be parasailing and y be horseback riding.
3y + 2x = 192
2y + 3x = 213
Multiply each equation by the number in front of the y of the other equation:
2 x (3y + 2x = 192)
3 x (2y + 3x = 213)
Which results in:
6y + 4x = 384
6y + 9x = 639
Simply minus the two equations to get rid of the y:
6y - 6y = 0
4x - 9x = -5x
384 - 639 = -255
The negatives cancel out which give a result:
5x = 255
x =
x = 51
So parasailing costs $51
Now you can simply plug this value into one of the equations:
3y + (2 x 51) = 192
192 - 102 = 3y
90 = 3y
y =
y = 30
So horseback riding costs $30!
Hope this helps.
