ANSWER:
The 1st one: -3x + y = 5
ABOUT STANDARD FORM:
- Ax + By = C
- A & B & C are integers
- A & B are both non - zero
- This form is good to use when wanting to find the x & y intercepts of a line
y - 2 = 3(x + 1) --- IN POINT SLOPE FORM
y - 2 = 3x + 3
+ 2 + 2
y = 3x + 5 --- IN SLOPE INTERCEPT FORM
-3x -3x
-3x + y = 5 --- STANDARD FORM
Hope this helps you!!! :)
The volume of a sphere is calculated like so:
v = 4*pi*r^3/3
so half sphere will have half that volume:
v = (<span>4*pi*r^3/3)(1/2)
</span>v = <span>4*pi*r^3/6
</span>plug in the data:
v = <span>4*pi*(10)^3/6
</span>v = 2094.4
that is the volume of the half sphere
Answer: $50.50
Step-by-step explanation:
$250.49-$199.99=$50.50
21/7=3mins per wall with 5 people.
Because we assume that all of the people paint at the same rate, 3 X 5=15 mins for one person working alone.
15/3=5 mins per wall with 3 people X 10 people= 50 mins for 3 people to paint 10 walls.
The answer is 50 mins.
Answer:
11/ 42. *. X^ 2. * X = I/3 X A * h; if E = 1/3 A
Then the answer is EX
Step-by-step explanation:
Volume of cone= 1/3 * base area * height
= 1/3 * pi* (X/2)^2 * X
= 1/3. * 22/ 7 * X^3/4
= 22/ 21 * X^3 / 4
= 11/21 *. X^2/ 2. *. X
= 11/ 42. * X^3
= 11/ 42. *. X^ 2. * X
