Please help me with this
Answer:
The length= 16cm
The width= 6cm
The two long sides are 8cm both so 8 + 8 = 16
And the two short sides are 3cm both so 3 + 3 = 6
So your length should be 16cm and your width 6cm

A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive
Answer:
Angle of elevation = 80°
Step-by-step explanation:
A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive?
To solve for angle of elevation, we use the Trigonometric function of Tangent.
tan θ = Opposite side/Adjacent side
Opposite side = Height of the tower = 217 ft
Adjacent side = 38ft
tan θ = 217/38
tan θ = 5.6315789474
θ = arc tan 5.6315789474
= 79.930937301°
Approximately = 80°

A bicycle store costs $2250 per month to operate. The store pays an average of $40 per bike. The average selling price of each bicycle is $70. How many bicycles must the store sell each month to break even?
Answer:
75
Step-by-step explanation:
Given That :
Operation cost = $2250 per month
Purchase price per bike = $40
Average selling price per bike = $70
How many bicycles must the store sell each month to break even ;
Break even point = point at which there is net profit / loss = 0
Let number of bicycles store must sell = x
Operation cost + (purchase price * Number of bicycles) = selling price * Number of bicycles
2250 + 40x = 70x
2250 = 70x - 40x
2250 = 30x
x = 2250 / 30
x = 75
To break even 75 bicycles must be sold
Solve for h! Please add an explanation if you can
Answer:
the answer to this problem is H = -12
Answer:
h=-12
Step-by-step explanation:
You have to isolate h. As such, add 1 to both sides in order to get rid of the -1 on the left side. Then, multiply by 6 on both sides in order to get h by itself.

[tex]\frac{x^2}{3}-\frac{1}{2}=\frac{x}{3}[/tex]
Because there are 3 and 2 as the denominators. Find the lowest number that both 3 and 2 can divide without any quotients, which is 6.
Multiply all whole equation by 6.
[tex]\frac{x^2}{3}(6)-\frac{1}{2}(6)=\frac{x}{3}(6)\\2x^2-3=2x[/tex]
We should get like this. Then move 2x to subtract.
[tex]2x^2-2x-3=0[/tex]
Because the polynomial is a two-degree and a quadratic equation. We solve the value of x by either factoring, using the formula or completing the square.
But I'll use the Quadratic Formula instead as the factoring doesn't seem to work for the Quadratic Equation with square root answers.
[tex]x=\frac{-b±\sqrt{b^2-4ac} }{2a}[/tex]
This is the formula of Quadratic Equation. Ignore the weird letter as it just randomly appears and can't be deleted.
[tex]x=\frac{-(-2)±\sqrt{(-2)^2-4(2)(-3)} }{2(2)} \\x=\frac{2±\sqrt{4+24} }{4} \\x=\frac{2±\sqrt{28} }{4}\\x=\frac{2±2\sqrt{7} }{4} \\x=\frac{1±\sqrt{7} }{2}[/tex]
Therefore, the answer is x = (1±√7)/2

The elevations of four points above sea level there are -47 ft, -20 ft,-8 ft, and -18 ft. The elevation of the point closest to sea lvl (level) is _____ ft, and the elevation of the point farthest from sea lvl is _____ ft. (FILL IN THE BLANKS PLS HELP)
Answer:
The elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
Step-by-step explanation:
Let's assume the elevation above the sea level is on a number line, then we have to arrange the given number from lowest to highest. These are the numbers in ascending order.
–42ft, –20ft, –18ft, –8ft.
From here we see that, the elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
