Answer:

There are 49 white marbles.

Step-by-step explanation:

w + g = 62        (w = white and g = green marbles).

w = 4g - 3

w - 4g = -3        Subtract this equation from the first equation:

g - (-4g) =  62 - (-3)

5g = 65

g = 65/5 = 13.

So w = 62 - 13 = 49.

What is the tangent ratio for
yawa3891 [41]

Answer:

tan T = 3/4

tan U = 4/3

Step-by-step explanation:

The tangent ratio is opposite / adjacent. The ratio will vary for each angle since the perspective of each angle will be different. For example Angle T has an adjacent side of 4 while Angle U has an adjacent side of 3. The tangent ratios for Angles U and T are listed below:

tan T = 3/4

tan U = 4/3

Which is a right triangle formed using a diagonal through the interior of the cube? A cube. The top face has points G, B, C, F a
Black_prince [1.1K]

Answer: The correct option is triangle GDC

Step-by-step explanation: Please refer to the picture attached for further details.

The dimensions give for the cube are such that the top surface has vertices GBCF while the bottom surface has vertices HADE.

A right angle can be formed in quite a number of ways since the cube has right angles on all six surfaces. However the question states that the diagonal that forms the right angle runs "through the interior."

Therefore option 1 is not correct since the diagonal formed in triangle BDH passes through two surfaces. Triangle DCB is also formed with its diagonal passing only along one of the surfaces. Triangle GHE is also formed with its diagonal running through one of the surfaces.

However, triangle GDC is formed with its diagonal passing through the interior as shown by the "zigzag" line from point G to point D. And then you have another line running from vertex D to vertex C.

Merideth measured 3.25 cups of flour and 1.625 cups of brown sugar into
Fiesta28 [93]

Answer:

Step-by-step explanation:

This is just an addition question. If you have a calculator just add the numbers.

3.25 + 1.625 = 4.875 cups in the bowl.

Sometimes you can use another method. Sometimes it is shorter.

3 1/4 + 1 5/8 = 3 2/8 + 1 5/8 = 4 7/8.

7/8 = 0.875
