Answer:

hope like it

Step-by-step explanation:

A scale factor is usually a decimal which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x. For example, doubling distances corresponds to a scale factor of two for distance, while cutting a cake in half results in pieces with a scale factor for volume of one half. The basic equation for it is image over preimage.

In the field of measurements, the scale factor of an instrument is sometimes referred to as sensitivity. The ratio of any two corresponding lengths in two similar geometric figures is also called a scale.

How can the statement below be rewritten as a conditional statement in if-then form?

Irina-Kira [14]

Answer:

<h2>If two angles measures 180 degrees, then they form a linear pair.</h2>

Step-by-step explanation:

The conditional statement should be this way, because after the word ''if'', should be placed the condition, and after the word ''then'', should be the consequence.

-y varies inversely with x. When y = 9.6, x = 12. What is the value of k, the constant of inverse variation?

alisha [4.7K]

Question 1:

For this case we have an equation of the form:

$y = \frac {k} {x}$

Where,

<em>k: inverse variation constant. </em>

Then, substituting values we have:

$y =\frac {k} {x}$

From here, we clear the value of k.

We have then:

$k = 9.6 * 12\\k = 115.2$

Answer:

the constant of inverse variation is:

$k = 115.2$

Question 2:

For this case we have:

$y = \frac {k} {x}$

Where,

<em>k: constant of variation. </em>

Then, substituting the value of the constant we have:

$y =\frac {5.6} {x}$

We now substitute the value of x:

$y = \frac {5.6} {4}\\y = 1.4$

Answer:

the value of y when x = 4 is: $y = 1.4$

Solve the system of equations given below.<br> -5x = y – 5<br> -2y = -x-21

irakobra [83]

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}-5x=y-5&\text{subtract y from both sides}\\-2y=-x-21&\text{add x to both sides}\end{array}\right\\\left\{\begin{array}{ccc}-5x-y=-5&\text{multiply both sides by (-2)}\\x-2y=-21\end{array}\right\\\underline{+\left\{\begin{array}{ccc}10x+2y=10\\x-2y=-21\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad11x=-11\qquad\text{divide both sides by 11}\\.\qquad x=-1\\\\\text{put the value of x to the first equation:}\\\\10(-1)+2y=10\\-10+2y=10\qquad\text{add 10 to both sides}\\2y=20\qquad\text{divide both sides by 2}\\y=10$

Which of the following is true? |−8| < 6 |−6| < |−8| |8| < |−6| |−6| < −8

tamaranim1 [39]

Answer: The second choice

Step-by-step explanation:

Absolute value is the distance a number is from 0 on the number line. Thus, the absolute value of -8 is 8, which is greater than the absolute value of -6, or 6.

Answer:

a 8 1/4 c

Step-by-step explanation:

I converted to decimals first. 4.5 c water to 2 c cream. wants to use 3.66 cream. 3.66/2= 1.83. she is increasing cream by 1.83%, next multiply same % to water. 4.5 cups * 1.83 = 8.235 which is closest to 8.25= 8 1/4
