Answer:
70
Step-by-step explanation:
angles across from each other on shared lines are equal to each other.
$28.20 because you have to multiply 35.25 by 0.20 (20%) which equals 7.05. Then you subtract 35.25 by 7.05 because it is 20% off, which results in the answer of $28.20
The tensile strength of spider silk is about 1150 MPa, which is 1.15 x 10^9 N/m².
<span>So given that the diameter of the spider silk is 0.15 mm or 1.5 x 10^-4 m. The cross sectional area is approximately: </span>
<span>A = πr² = (3.14)(1.5 x 10^-4 / 2)² = 1.767 x 10^-8 m² </span>
<span>So this means that the amount of force we can apply before the the silk thread is broken is: </span>
<span>F = PA = (1.15 x 10^9)(1.767 x 10^-8) = 20.32 N </span>
<span>F = mg, so m = F/g = (20.32)/(9.81) = 2.07 kg!!! </span>
Answer:
D'(-2, 0)
E'(6, 4)
Step-by-step explanation:
If DE is dilated by the scale factor 2, we can multiply the endpoints by the scale factor 2 to find the coordinates of D' and E'!

Answer:
29 feet above sea level
Step-by-step explanation:
One floor is 9 feet high, so the top of the first floor will be 9 feet above the ground.
The ground is also 20 feet above sea level, so add 9 to this to find how many feet above sea level the top of the first floor is:
20 + 9
= 29 feet above sea level
