A person standing on level ground is 3020 feet away from the foot of a building. If the height of the building is 2534 feet, find the angle of elevation formed at the point where the person is standing to the nearest degree
Answer:
40°
Step-by-step explanation:
Base length, b = adjacent = 3020 feets
Height of building, h = opposite = 2534 feets
The angle of elevation formed :
Using the trigonometry relation:
Tan θ = opposite / Adjacent
Tan θ = 2534 / 3020
Tan θ = 0.8390728
θ = tan^-1(0.8390728)
θ = 39.999
= 40°

Hey can you please help? I am struggling a lot don’t know how to solve this
Answer:
64.8
Step-by-step explanation:
Pythagoreon Theroem
a^2 + b^2 = c^2 in this situation it would actually be the opposite, seeing where the "x" is (on a leg) c^2 - b^2 = a^2. First take the square of 67 and 17
67 squared is 4489 and 17 squared is 289 then subtract both results
4489-289 = 4200 take the square root of this number

Allison is saving to buy a $500 bicycle by working during
summer vacation,
• The job pays her $8 for every 1 hour worked.
• Allison works exactly 20 hours each week.
If she works for 4 weeks and buys the bicycle, how much
money will she have left over?
Answer:
140.00
Step-by-step explanation:
20 x 4 = 80 hours worked
80 x 8.00 = $640.00
640.00 - 500.00 = 140.00

Answer:
-4x + y + 6z
Step-by-step explanation:
Combine like terms (Terms with the same variable):
(2x + 5y - z) + (-6x - 4y + 7z)
Add straight across:
2x - 6x = -4x
5y - 4y = y
-z + 7z = 7z - z = 6z
-4x + y + 6z is your answer.

PLEASE HELP ASAP! DO IN 5 MINUTES! WILL MARK BRAINLIEST!
Answer:
15
Step-by-step explanation:
Given
Hypotenuse (h) = 17 cm
perpendicular (p) = 8 cm
base (b) = ?
we know by using Pythagoras theorem
b = √h² - p²
= √ 17² - 8²
= √ 225
= 15 cm
or
YZ = 15 cm

So in this equation we have to solve using PEMDAS, or parentheses, exponents, multiplication, division, addition, then subtraction, going from left to right. So first, i deal with whats in the parentheses, but since it cannot be subtracted, I next go on to the next step. Since there are no exponents, our next step is to multiply or distribute 2 into (-3-6x). In other words, i multiply 2 by -3 and 2 by -6x. This is going to be -6 -12x. After that, i add and subtract common factors, so 3x-12x is -9x, and -4-6 is -10. This leaves us with -9x-10=0. I add 10 to each side according to addition property of equality. Thus, the equation is -9x=-10. Divide both sides by -9, by the division property of equality, and u get 10/9. If you want a decimal answer, type it into a calculator.
is 14:12 equivalent to 7:5
Answer:
Yep,
it is correct!
Answer:
No
Step-by-step explanation:
14:12 is not equivalent to 7:5 because if you divide 14 by 2, you would get 7. If you divide 12 by 2, however, you will get 6. So the equivalent ratio for 14:12 is 7:6.

Find the probability that the team will win exactly one of the two matches
Answer:
The probability is 0.341
Step-by-step explanation:
Here, we want to calculate the probability that the student will win exactly one of the two matches
This means that;
If they win on Saturday, they lose on Sunday
or
If they lose on Saturday, they win on sunday
So either of the two scenarios will give that the team will win on either of the two days
Mathematically, we have that;
(0.45 * 0.33) + (0.55 * 0.35)
= 0.1485 + 1925
= 0.341

help me pls and show work 8th grade math
Answer:
Find the slope this way Hanna,
Step-by-step explanation:
slope = m
m = (y2-y1) / (x2-x1)
you are given the two points
P1 = (-2,-6) in the form (x1,y1)
P2 = (2,2) in the form (x2,y2)
plug those into the slope formula above
m = (2-(-6) ) / (2 - (-2) )
m = (2 +6) / (2+2)
m = 8 / 4
m = 2
