Answer: 15.7 cups of popcorn

Step by step solutions:

V=pi*r^2*h
V=3.14*3^2*8
V=226.08 in^3

Now divide the volume by the volume of a cup of popcorn.

226.08 in^3/(14.4 in^3)=15.7 cups

HELP!!! RST has vertices R(-3, - 1), S(0,3), and t(3,0). What type of triangle is RST?

VladimirAG [237]

<h3>Answer: C) scalene</h3>

======================================================

Explanation:

Use the distance formula to calculate the distance from R to S. This is identical to the length of segment RS.

$R = (x_1,y_1) = (-3,-1) \text{ and } S = (x_2, y_2) = (0,3)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-3-0)^2 + (-1-3)^2}\\\\d = \sqrt{(-3)^2 + (-4)^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5\\\\$

Segment RS is exactly 5 units long.

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

Repeat similar steps to find the length of segment ST

$S = (x_1,y_1) = (0,3) \text{ and } T = (x_2, y_2) = (3,0)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-3)^2 + (3-0)^2}\\\\d = \sqrt{(-3)^2 + (3)^2}\\\\d = \sqrt{9 + 9}\\\\d = \sqrt{18}\\\\d \approx 4.2426\\\\$

ST is roughly 4.2426 units long.

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

Lastly, let's calculate the length of segment TR.

$T = (x_1,y_1) = (3,0) \text{ and } R = (x_2, y_2) = (-3,-1)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-(-3))^2 + (0-(-1))^2}\\\\d = \sqrt{(3+3)^2 + (0+1)^2}\\\\d = \sqrt{(6)^2 + (1)^2}\\\\d = \sqrt{36 + 1}\\\\d = \sqrt{37}\\\\d \approx 6.0828\\\\$

TR is about 6.0828 units long.

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

Summary of the segment lengths:

RS = 5 exactly
ST = 4.2426 approximately
TR = 6.0828 approximately

The three sides are different lengths.

Therefore, the triangle is <u>scalene</u>.

4/5, √9, -0.95, √32/8, 2.9, - √6 PLEASE order from least to greatest

Eva8 [605]

Answer:

-√6 -0.95 √32/8 4/5 2.9 √9

Step-by-step explanation:

4/5, √9, -0.95, √32/8, 2.9, - √6

4/5 = 0.8

√9 = 3

√32/8 = 4√2 / 8 = √2/2 = 0.707

-√6 = -2.449

-√6 -0.95 √32/8 4/5 2.9 √9

Solve on the interval 0,2pi) 2cscx-3=-5

nydimaria [60]

We have that

<span>2cscx-3=-5---------> 2cscx=-5+3---------> cscx=-2/2---------> cscx=-1

we know that
csc x=1/sin x
then
1/sin x=-1--------------> sin x=-1
x=arcsin (-1)---------> x=-90</span>°
x=-90°---------------> 360°-90°-----------> x=270°------------> 3pi/2<span>

the answer is
x=3pi/2 radians
