Malaya is standing directly between a 90 foot tall courthouse and a 54 foot tall bank. If the angle of elevation from the point where Malaya is standing to the top of the courthouse is 72 degrees, while the angle of elevation to the top of the bank is 35 degrees. What is the distance between the courthouse and the bank? Show all your work to get credit!
Answer:
106.36 ftStep-by-step explanation:
Let the distance from the point Malaya is standing to the courthouse be x and the distance to the bank is y
x + y is the distance between the courthouse and the bankThen we have:
x/90 = cot 72° ⇒ x = 90 cot 72° = 90*0.3249196962 = 29.24 ft (rounded)y/54 = cot 35° ⇒ y = 54 cot 35° = 54*1.4281480067 = 77.12 ft (rounded)x + y = 29.24 + 77.12 = 106.36 ftAnswer:
106.3ft
Step-by-step explanation:
x= tan72=90/x
x= 90/tan 72
x= 29.2
y= tan35=54/y
y= 54/tan35
y= 77.1
x+y= answer
29.2 + 77.1 = 106.3

Answer:
19.25 miles
Step-by-step explanation:
Antoine's rate before lunch was ...
(5.25 mi)/(3 h) = 1.75 mi/h
Then his rate after lunch was ...
2×(1.75 mi/h) = 3.5 mi/h
The distance he hiked after lunch was ...
distance = speed × time
(4 h)×(3.5 mi/h) = 14 mi
The distance Antoine hiked is the total of his before-lunch distance and his after-lunch distance:
5.25 mi + 14 mi = 19.25 mi

Which expression is equivalent to 6x + 7 – 12.2 - (32 + 2) - x?
Solve algebraically for all values of x:
- 4x^4 + 36x^3 - 80x2 = 0
Given:
The equation is
[tex]-4x^4+36x^3-80x^2=0[/tex]
To find:
The value of x.
Solution:
We have,
[tex]-4x^4+36x^3-80x^2=0[/tex]
It can be written as
[tex]-4x^2(x^2-9x+20)=0[/tex]
Splitting the middle term, we get
[tex]-4x^2(x^2-5x-4x+20)=0[/tex]
[tex]-4x^2(x(x-5)-4(x-5))=0[/tex]
[tex]-4x^2(x-5)(x-4)=0[/tex]
Using zero product property, we get
[tex]x^2=0,x-5=0,x-4=0[/tex]
[tex]x=0,x=5,x=4[/tex]
Therefore, the values of x are 0, 4 and 5.
If a soccer team won 7 of Its 13 games, what was their ratio of wins to losses? Assume that there were no tle games.
A. 1 to 2
B. 7 to 20
C. 7 to 6
D. 7 to 13
Answer: The answer would be D, 7 to 13.
Step-by-step explanation: It is 7 to 13 because you are assuming there are no other games. So you can see it is 7 to 13 because they have only won 7 out of 13 games.

ANSWER FOR A BRAINLIEST Solve the system of two variables by substitution
Answer:
Substitution is when you isolate a variable-
3) We can divide the first equation by 6 to get x+y=-1, then isolate to get y=-1-x. We plug this into the second equation to have 3x+(-1-x)=-13. We simplify and get 2x=-12 so x=-6. We plug this back into the first equation and get -6+y=-1 so y=5. So the answer as an ordered pair is (-6,5).
4) We can isolate the second equation to get x=2y+11. We substitute this into the first equation to have -7(2y+11)-2y=-13. We simplify and get -16y=64 so y=-4. We plug this back into the second equation and get x+8=11 so x=3. So the answer as an ordered pair is (3,-4).

4 x 2/7 Pls solve it for me
Answer:
8/7 or 1 1/7
Step-by-step explanation:
4/1 x 2/7 = 8/7
how do u do this but in clear
Answer:
Look at the explanation :)
Step-by-step explanation:
Angle 2 and 3 are supplementary angles, which means they are equal.
Therefore, if
Angle 2 = 4x - 26
and
Angles 3 = 3x + 4,
It means that 4x - 26 = 3x + 4
Solve it,
4x = 3x + 30
x = 30
Input x to each angles,
Angle 2,
4(30) - 26 = 120 - 26 = 94
Angle 3,
3(30) + 4 = 90 + 4 = 94
Hope this helps :)

Evaluate the expression below.
(8.1+7.9)x - (25 division 5)x
Answer:
11x
Step-by-step explanation:
Start by simplifying the parentheses. (8.1+7.9)=16 and (25/5)=5. Next, distribute each x into the parentheses. You should now have 16x-5x. Since they share like terms, you can subtract them.
CAN SOMEONE HELPPP WITH 6 3/4 + 2 5/7 PLEASE
Answer:
9 13/28
Step-by-step explanation:
Add whole numbers
Change bottom number of fraction to common factor
add
figure out how much is leftover
done!
Answer: 9 13/28
Step-by-step explanation:
First turn your mixed numbers into improper fractions. 6 3/4 becomes 27/4 and 2 5/7 becomes 19/7. Now we need to make the denominators match. The least common multiple of 7 and 4 is 28. 27/4 becomes 189/28 and 19/7 becomes 76/28. We can now add these to get 265/28. This improper fraction can now be turned back into a mixed number. 28 will go into 265 evenly 9 times with 13 left over. Answer is 9 13/28
