Can you please explain some more detail or post a pic ?
Use the slope-intercept form y=mx+b
Answer:
$0.067
Step-by-step explanation:
Total cost of 16 bags = $12.80
weight in 1 bag = 12 ounce
weight in 16 bag = 16 * weight in 1 bag
weight in 16 bag = 16* 12 ounce = 192 ounce
Thus,
192 ounce cost = Total cost of 16 bags= $12.80
cost of 182 ounce = $12.80
to find cost of 1 ounce , we divide both side by 182
cost of 1 ounce = 12.80/192 = $0.067
Thus,
the unit cost per ounce is $0.067
Because the 2 triangles are similar, find the ratio of 2 known sides.
Side XY = 10
Side AB = 25
25 / 10 = 2.5
This means the larger triangle is 2.5 times larger than the smaller one.
Now find the side of the smaller triangle, that would be the same side as X on the larger triangle and multiply that by 2.5.
XZ is the same side as AC
So X = 6 x 2.5
X = 15
Answer:
a = 254.5 mm² ( if using accurate value of π)
a = 254.4 mm² (if using 3.14 as approximate value of π)
Step-by-step explanation:
a = πr²
a = π * 9²
a = π * 81
(note using π = 3.1415926536)
a = 254.4690049408
Rounded
a = 254.5 mm²
(a = 254.4 If using π = 3.14)
