Answer:
A ≈ 3420 cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius ) , then
A = π × 33² = 1089π ≈ 3420 cm² ( to 3 significant figures )
Answer:
The line would be y = -1/4x + 27/4
Step-by-step explanation:
In order to find this, we first need to note that the original slope is -1/4. And since parallel lines have the same slope, we know our new line will have that same slope. Now, we can use that slope and the point in point-slope form and solve for y.
y - y1 = m(x - x1)
y - 6 = -1/4(x - 3)
y - 6 = -1/4x + 3/4
y = -1/4x + 27/4
A18
18 is the exponent, am not sure because I see this topic a really long time ago, but I think that you multiply the exponent because the sign is multiplication
Answer:
$1470
Step-by-step explanation:
sneakers : boots
15 : 19
15 cost sneakers
------ = -------------------
19 570
using cross products
15 * 570 = 19 * sneakers
8550=19 * sneakers
divide by 19
8550/19 = sneakers
sneakers = 450
total cost = 2* sneakers + boot
total cost = 2 * 450 + 570
total cost = 900 + 570
total cost = 1470
The answer is B I did something like this before I believe that is the answer
