If a person has the values for an object's density and volume, what value can be calculated? the object's size the object's mass

irina [24]

Answer:

The object's mass.

Explanation:

The formula d=m/v.

d --> density

m--> mass

v --> volume

With density and volume given, you can calculate the mass of the object.

Which of the coordinate points below will fall on a line where the constant of proportionality is 1/4? Select all that apply. A)

kompoz [17]

Answer:

A) (4,1) C) (12,3) D) (20,5)

Step-by-step explanation:

Required

Which has a constant of proportionality of 1/4

To solve this, we make use of:

$y = kx$

Where k is the constant of proportionality.

Solve for x

$k = y/x$

<u>Testing the given options</u>

A) (4,1)

$k = y/x$

$k =1/4$

B) (8,12)

$k = y/x$

$k =12/8$

$k =3/2$

C) (12,3)

$k = y/x$

$k = 3/12$

$k = 1/4$

D) (20,5)

$k = y/x$

$k = 5/20$

$k = 1/4$

E) (12,6)

$k = y/x$

$k =6/12$

$k =1/2$

On a recent math test, Samantha scored 3 points for each of the 18 multiple choice questions she

Crazy boy [7]

The required expression will therefore be:

(3×18) + (5×6) + 4

Her total score is 88points :

From the question given, we are told that Samantha scored 3 points for each of 18 multiple choice questions, this means that the total points made here is expressed as:

(3 × 18) ...1

If she got 5 points for each of the 6 short response questions she answered

correctly, the total point made will be expressed as;

(5×6) ... 2

Total score for an additional 4 points for the bonus question will be "4"

Expression for her total score will be the sum of all the expression above as thus:

(3×18) + (5×6) + 4

Taking the sum, her score will be:

= (3×18) + (5×6) + 4

= 54 + 30 + 4

= 84 + 4

= 88 points

The required expression will therefore be:

(3×18) + (5×6) + 4

Her total score is 88points

Carlos solved a system of linear equations. He found that exactly one point satisfied both equations. What do you know for certa

blagie [28]

Answer:

The two lines intersect (in other words, they have a common meeting points)

Step-by-step explanation:

Thinking process:

A linear equation takes the form of $y = mx + c$

where , m = gradient

c = y-intercept (point where the line cuts the y-axis)\

Suppose we have these two linear equations: $y = 2x + 4\\ 2y = -6x -1$

We can find the point of intersection by solving the two equations simultaneously like this:

sub y = 2x + 4 into equation (2) gives:

2(2x+4) = -6x -1

solving yields $x=$ - 0.9

Substituting x= -0.9 into equation 1 yields:

$y = 2 (-0.9) + 4\\ = -1.8 + 4\\ = 2.2$

y = 2.2

In terms of the Cartesian coordinates (x, y) the point of intersection will be (-0.9, 2.2)

Hence, the point of intersection is a solution of two linear equations.
