Area of flask: 63.62
Diameter: 4.5
Radius: 4.5 divided by 2
Radius: 2.25
Pi: 3.14
Volume:
1- 4/3(PI)(radius) by cubic square
2- 4/3(3.14)*(2.25) by cubic square
Answer: 47.71
Area of tank:
7-2=5
(it tells u to leave 2cm of the height without water)
15(L) x 9(W) x 5(D) = 675
675-47.71= 627.69
1 Liter= 1000 Cm
627.69 Cm = 0.62769 Liters
( round to nearest 0.1 liter )
Answer: 0.6 liters
A
The rate of change is 65. It means that you or the vehicle is traveling 65 miles per hour
For this you do Pythagorean theorem so
7^2+12^2=x^2
49+144=x^2
193=x^2
x=squareroot193
so you put 193 in the green box.
hope this helped❤️
Answer: A. y+8=-2(x-4)
Step-by-step explanation: Point-slope form is y-y₁=m(x-x₁), in which you only substitute three values: the slope, and the x and y coordinate. So, since the slope is -2, you replace it with m. And, if the point is (4, -8), you would substitute the 4 in for x₁, but the -8 is a little more complicated because it is negative. Basically, the negative and the minus sign cancel out and it becomes a plus sign.
Hope this helped! Good luck!
M=cost per movie
v=cost per video game
2m+5v=33
8m+3v=30
use elimination
eliminate movies
mutliply first equation by -4 and add to 2nd
first equation becomes -8m-20v=-132
add the 2 equations
-8m-20v=-132
<u>8m+3v=30 +</u>
0m-17v=-102
-17v=-102
divide both sides by -17
v=6
subsiutute back
2m+5v=33
2m+5(6)=33
2m+30=33
minus 30 both sides
2m=3
divide 2
m=1.5
rental cost per movie is $1.50
rental cost per video game is $6
