You want to determine the height of the screen at a drive-in movie theater. You use a cardboard square to line up the top and bottom of the screen structure. The vertical distance from the ground to your eye is 5.5 ft and the horizontal distance from you to the screen is 14 ft. The bottom of the screen is 6 feet from the ground. Approximate the height of the screen to the nearest tenth.
I hope this helps with your question.

Question:
The taxi company charged a pick-up fee of $4.30 plus $1.25 per mile. The total fare was $35.55, not including the tip. How many miles was the taxi ride?
Answer:
total miles 25
Prove:
35.55-4.30=31.25
31.25/1.25= 25
OR Explained
sub 4.30 35.55 - 4.30 = 31.25
Divide 1.25 31.25/1.25 = 25
Final answer is 25

Answer:
m = n = 5√2
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you ...
Sin = Opposite/Hypotenuse
sin(45°) = m/10
m = 10·sin(45°) = 10·(√2)/2 = 5√2
The triangle is isosceles, so m = n.
n = m = 5√2
_____
The side ratios of an isosceles right triangle are 1 : 1 : √2. That is, the legs are 10/√2 = 5√2 in this triangle. It can be useful to remember these ratios for this "special" triangle.

Please help I asked this question earlier and nobody answered! :(
Answer:
B
Step-by-step explanation:
One way to tell is to put both equations into slope-intercept form. That form is usually written [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.
Solve the first equation for y.
[tex]6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2[/tex]
The slope of this line is -3, and its y-intercept is 5/2.
Solve the second equation for y.
[tex]y+3x=2\\y=-3x+2[/tex]
The slope of this line is -3 and its y-intercept is 2.
The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.

T Frank leans a 10 foot ladder against the side of his house, but because of a
rose bush next to the house, the bottom of the ladder is 3 feet away from the
wall. How high will the top of his 10 foot ladder really reach? feet
Answer:
9.5 feet
Step-by-step explanation:
We use Pythagorean thm:
a² + b² = c²
Given:
b = 3
c = 10
Work:
a² + b² = c²
a² + 3² = 10²
a² + 9 = 100
a² = 91
[tex]\sqrt{a^2} =\sqrt{91}[/tex]
a = 9.5

DG=9
Step-by-step explanation:
2x-4=x+7
x-4=7
x=11
x-2=11-2=9
Find the value of x
Step-by-step explanation:
Given Angle AOC = 90,
Angle AOB + Angle BOC = 90
[tex]3x + 46 + 14 = 90 \\ 3x + 60 = 90 \\ 3x = 90 - 60 \\ 3x = 30 \\ x = 30 \div 3 \\ = 10[/tex]
Answer:
B) 10
Step-by-step explanation:
It is given that the (m<AOC) is (90) degrees. It is also given that (<AOB) and (<BOC) compose (<AOC). Therefore, the following statement can be made;
(m<AOB) + (m<BOC) = (m<AOC)
Substitute,
(3x + 46) + (14) = (90)
Simplify,
3x + 60 = 90
Inverse operations,
3x + 60 = 90
-60 -60
3x = 30
/3 /3
x = 10

I need to print x photos for my scrapbook I called two different stores to ask about the cost of printing photos The first store charges a fee of $3.79 to use the photo machine and then an additional $0.25 per photo. The second store charenly a $0.99 fee to use the photo machine, but the additional cost per photo is $0.35 After comparing the two stores, I realize my overall cost will be the same at each store. What is the value of x, the number of photos I need to print?
Answer:
x=28
Step-by-step explanation:
3.79+0.25x=0.99+0.35
-0.35x -0.35x
3.79+-0.10x=0.99
-3.79 -3.79
-0.10x=-2.8
-0.10x/-2.8
x=28

Answer:
x = (3-2√11)/5 ; x= (3+2√11)/5
Step-by-step explanation:
Δ/4 = (b/2)^2 - ac where b is the term that multiplies x, a is the therm that multiplies x^2 and c is the therm without x
Δ/4 = (-3)^2 - (-7*5) = 9 + 35 = 44 = 2^2 *11
x1 = (3 - √2^2 *11)/5 = (3-2√11)/5
x2 = (3+ √2^2 *11)/5 = (3+2√11)/5
What is the first step to solve this equation:
11 - 3x = 44
Question 3 options:
Add 3 to both sides
Add 11 to both sides
Subtract 11 from both sides
Divide 3 on both sides.
