Answer:

D. 4

Step-by-step explanation:

We know that the square of (+4) is 16 and also for (—4) is 16. We normally takes interest in positive square value for a square root. Therefore, The principal square root of 16 is 4

Find the value of x.

melamori03 [73]

9514 1404 393

Answer:

(b) 48

Step-by-step explanation:

In this geometry, the altitude (x) is the root of the product of the segments of the hypotenuse.

x = √(36·64) = √36×√64 = 6×8

x = 48

_____

All of the triangles are similar, so the ratios of corresponding sides are the same.

short side/long side = x/64 = 36/x

x^2 = (64)(36) . . . . as above

In order to slove the following system of equations by addition, which of the following could you do before adding the equations

Vladimir [108]

Answer:

B. use multipliers -3 and 2

Step-by-step explanation:

If you're solving the system by "addition," multiplying the equations by the chosen numbers needs to result in opposite coefficients for one of the variables.

<h3>Effect of answer choices</h3>

A. The system becomes ...

12x -6y = 21
12x -12y = 60

No variable has opposite coefficients.

B. The system becomes ...

-12x +6y = -21
6x -6y = 30

The y-variable has opposite coefficients. This is a good choice.

C. The system becomes ...

12x -6y = 21
6x -6y = 30

No variable has opposite coefficients.

D. The system becomes ...

4/3x -2/3y = 7/3
3x -3y = 15

No variable has opposite coefficients.

<em>Additional comment</em>

The simplest "no brainer" solution is to use the coefficients of one of the variables, negating one of them. Multiply each equation by the opposite equation's coefficient. Here, the y-coefficients are -2 and -3, and the multipliers of answer choice B are -3 and 2, consistent with this advice. (The sign of 2 was changed.)

A biologist uses a box-shaped fish trap that measures 1/4 meter by 2/3 meter by 3/5 meter. What is the volume of the trap in cub

Zolol [24]

To find the volume of a box-shaped fish trap, we have to multiply the three dimensions of it:
(1/4 m)* (2/3 m)* (3/5 m)
= (1*2*3)/ (4*3*5) m^(3)
= 6/ 60 m^(3)
= 1/10 m^(3)
= 0.1 m^(3)

The volume of the box-shaped fish trap is 0.1 m^(3).

Hope this is helpful~
