Answer:
15205.3
Step-by-step explanation: H=30 R²=484 3.14=π →= rounded up to tenth V = Volume
<em><u>formula (no numbers): H x R² x π ÷</u></em><u> </u><u> (or 3) </u><em><u>= V</u></em>
<u><em>how i got the answer : 30 x 484 x 3.14 ÷ 3 = 15205.31 → 15205.3</em></u>
Answer:
y= 2x +3
Step-by-step explanation:
<u>S</u><u>lope-intercept</u><u> </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is 2, m= 2.
Substitute m= 2 into the equation:
y= 2x +c
Given that the y-intercept is (0, 3), c= 3.
Substitute c= 3 into the equation:
y= 2x +3
Thus, the equation of the line is y= 2x +3.
Answer:
width=4in.
length=13in
Step-by-step explanation:
let the width of the rectangle be x
then the length will be x+9
Area= length×width
52= (x+9)x
52= x²+9x
x²+9x-52=0
x²+13x-4x-52=0
x(x+13) - 4(x+13)= 0
(x-4)(x+13)=0
x=4 or -13
dimension cannot be negative
hence x=4in
the width is 4in. and the length is 4+9=13in.
