A rectangle has an area of 1,280.64 square miles and a base of 36.8 miles. What is the height?
Answer:
34.8 miles
Step-by-step explanation:
First, we know that Area = Length * Width. Let's plug in those values.
1,280.64 = x * 36.8 (I put the variable "x" there since we don't know what it is)
Now, solve for x (we want to have x by itself, so divide both sides by 36.8)
34.8 = x
Now that we know that the width of it is 34.8 miles, let's check our work.
34.8 * 36.8 = 1,260.64
This equation IS true, so:
The width of the rectangle is 34.8 miles. Hope this helps!

En una muestra de 50 restaurantes de comida rápida, la venta media fue de $3.000, y la desviación estándar, $200. El intervalo de confianza del 95% es
Respuesta:
(2945.411; 3054.589)
Explicación paso a paso:
Dado ;
Tamaño de la muestra, n = 50
Media, xbar = 3000
Desviación estándar, s = 200
Nivel de confianza, Zcrítico al 95% = 1,96
El intervalo de confianza se define como:
Xbar ± margen de error
Margen de error = Zcrítico * s / sqrt (n)
Margen de error = 1,96 * 200 / sqrt (50)
Margen de error = 54.589
Límite inferior = (3000 - 54.589) = 2945.411
Límite superior = (3000 + 54.589) = 3054.589
(2945.411; 3054.589)

The area of a right triangle is 3gh. Find the height if the base is 3gh.
Area of a triangle: A = 1/2bh
Answer: height is 2
Step-by-step explanation:
A = 1/2bh
A = 3; b (base) = 3. Substitute these values in the formula and solve.
3 = 1/2*3*h = 3/2 h
h = 3 * (2/3) = 2
Answer:
Height = 2
Step-by-Step Explanation:
So, I'm not sure if "gh" is a measurement. But I'm thinking it should be solved like this.
Area = 3gh
Base = 3gh
Height = ?
Plug & Chug
3gh = 1/2 (3gh)(h)
2/1 · 3gh = 1/2 (3gh)(h) · 2/1
[tex]\frac{(2)(3gh)}{(3gh)\\}[/tex] = [tex]\frac{(3gh)(h)}{(3gh)}[/tex]
h = [tex]\frac{(2)(3gh)}{(3gh)}[/tex]
h = 2

As an estimation we are told 5 miles is 8 km.
Convert 55 miles to km
Answer:
88 km.
Step-by-step explanation:
If 5 miles is 8 km,
55 miles is 88 km.
What you need to do is 55/5 = 11.
Then multiply that 11 to 8.
11 * 8 = 88.
Basically, if you are multiplying 5 by 11 to get 55, you need to multiply 8 by 11 to get 88.
The speed of sound (shockwave) in an explosion is 100mph. How many seconds does the shockwave reach 2km away?
Answer:
t = 44.73 s
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 100 mph = 44.704 m/s
We need to find the time taken by the shockwave to reach 2 km i.e. 2000 m
We know that,
Speed = distance/time
So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{2000}{44.704}\\\\t=44.73\ s[/tex]
So, it will take 44.73 seconds to reach 2 km.

(PLEASE HELP) Find the product of
(x+4)(x2+7x).
Answer:
x³ + 11x² + 28x
Step-by-step explanation:
(x + 4)(x² + 7x)
Each term in the second factor is multiplied by each term in the forst factor, that is
x(x² + 7x) + 4(x² + 7x) ← distribute parenthesis
= x³ + 7x² + 4x² + 28x ← collect like terms
= x³ + 11x² + 28x
[tex] \huge \underline{ \sf \: Solution}[/tex]
[tex](x + 4)( {x}^{2} + 7x) \\ = x( {x}^{2} + 7x) + 4( {x}^{2} + 7x) \\ = {x}^{3} + {7x}^{2} + {4x}^{2} + 28x \\ = {x}^{3} + {11x}^{2} + 28x [/tex]
