Step-by-step explanation:

$-3t+4=19\qquad\text{subtract 4 from both sides}\\\\-3t+4-4=19-4\\\\-3t=15\qquad\text{divide both sides by (-3)}\\\\\dfrac{-3t}{-3}=\dfrac{15}{-3}\\\\t=-5$

Betty's grade in science class is affected by the number of missing assignments. The table below shows the science grade percent

Angelina_Jolie [31]

Hi!

$y=-5x+95$

Plug in $15$ for $x$

$y=-5(15)+95$

Multiply $-5$ and $15$

$y=-75+95$

Add $-75$ and $95$

$y =15$

-------------------------------------------------------------------------------------------------------------

Betty's percentage is 15%.

The rate of change is the amount it changes for every missing assignment, therefore it would be -5.

A conical perfume bottle has a radius of 3.2 centimeters and a height of 3.9 centimeters.

ioda

For this case, we must find the volume of the perfume bottle, given by the volume of a cone.

$V = \frac {\pi * r ^ 2 * h} {3}$

Where:

r: It's the radio

h: It's the height

Substituting the values:

$V = \frac {3.14 * (3.2) ^ 2 * 3.9} {3}\\V = \frac {125.39904} {3}\\V = 41.79968 \ cubic \ centimeters$

Round off:

$V = 41.80 \ cubic \ centimeters$

Thus, the bottle contains 41.80 cubic centimeters of perfume

Answer:

Option C
