Hello there!

First, you need to replace that empty space by a letter. As usual, we replace that empty space by x or y. I pick X :)

\frac{5}{12} =   \frac{x}{48} 

Now, we do something called cross-multiply 

12*x = 48 * 5 

12x = 240

x =  240/12 

x= 20

The missing number is 20
----------------------

We can check if we got the answer right. Replace the hole by 20
so it will be
5/12 = 20/48

when divided 5 by 12, it equals to 0.41
when we divided 20 by 48, it equals 0.41

So yes, 20 is the missing number.


I hope this helps you. Please let me know if you have more questions.

Best of luck!

kirill [66]
The equation should look like :
[H+] = (1-a)(x) + (a)(y)
Where:
5.8 = -log [H+]
5.0 = -log x 
6.9 = -log y 
(1-a) = proportion of x
<span>a = proportion of y
so calculating a will give you the result of how many ounces are required</span>

Britney has a gift box in the shape of a cube. Each side of the box measures 15 centimeters. What is the volume of the gift box?
zavuch27 [327]
To get the volume, u have to multiply length*width*height. And cubes have equal side lengths, so 15*15*15= 3,375.

A helicopter hovers 500 m above a long straight road. There is a truck to the left and right of the helicopter. The angles of de
vivado [14]

Answer:

1045.01 rounded to the nearest hundredth

Step-by-step explanation:

First, we can draw this out. The angle of depression is the angle formed by the object at the top and the line formed by the object at the top and the object at the bottom.

If the truck on the left is truck A and the truck on the right is truck B, with the helicopter being the circle on top, there is one 60 degree angle of depression and one 20 degree one. If we make a point at the point in the road the helicopter is straight above, and we connect the points, we can form two right triangles, as shown. If we can calculate the lengths of sides x and y, we can add them up to find the length between the two trucks.

Starting with side x, we know one angle and the side length adjacent to that angle. We want to find the length opposite that angle. One formula that encompasses this is tan(θ) = opposite/adjacent. Therefore, tan(60) = x/500

tan(60) = x/500

multiply both sides by 500 to isolate the x

tan(60) * 500 = x

x = 866.0254

Similarly, with side y, we can say that tan(20) = y/500 and

tan(20) * 500 = y

y= 181.9851

The distance between the two trucks can be shown as x+y, so x+y= 1045.01 rounded to the nearest hundredth
