Answer:

Step-by-step explanation:

When doing distributive property, you have to multiply the outside number by all of the inside numbers

so 3(6 - 7a), you would have to do 3*6 and 3*-7a and then you would add those two values:

So in this case, you would do 18 + (-21a) which is just 18 - 21a.

Just to help you visualize distributive property better

3(6+8) = 3*6 + 3*8

4(20+5+3) = 4*20 + 4*5 + 4*3

10(15.5 - 24.4 + 23.21) = 10*15.5 + 10*(-24.4) + 10*23.21

I hope this helped, let me know if you have any questions

Answer: $312 ft^{2}$

Step-by-step explanation:

Area of Rectangle = bh = 16 ft x 18 ft = 288 $ft^{2}$

Area of Triangle = 1/2 bh = 1/2 x (16-12) ft x (6) ft x 2 (There's 2 triangles) = 24 $ft^{2}$

24 ft^2 + 288 ft^2 = 312 ft^2

You fly a hot air balloon 3.5 miles above the ground. What is the measure of BD⌢, the portion of Earth that you can see? Round y

STatiana [176]

Answer:

$\Delta s \approx 334.545\,m$

Step-by-step explanation:

Let assume that Earth is a sphere, the following trigonometric diagram is constructed and presented below. The central angle is given by this inverse trigonometric equation:

$\theta = 2\cdot \cos^{-1} \left(\frac{r}{r+h} \right)$

$\theta = 2\cdot \cos^{-1}\left(\frac{4000\,mi}{4000\,mi+3.5\,mi} \right)$

$\theta = 4.792^{\circ}$

The distance of the portion of Earth that can be seen is:

$\Delta s = \frac{4.792^{\circ}}{360^{\circ}}\cdot (2\pi)\cdot (4000\,mi)$

$\Delta s \approx 334.545\,m$
