Answer:
145.12 ft squared will be painted blue.
So the answer is B.
Explanation:
The area of the rectangle is 120 ft2 because 8 ft x 15 ft = 120 ft2
The area of the semi-circle is
because 3.14 x 4 (the radius) squared (or 16) is 50.24, then you divide it by 2 since it’s a semi-circle. 50.24 divided by 2 is 25.12.
Then you add the areas:
120 ft squared + 25.12 ft squared = 145.12 ft squared
Answer:
05.
Step-by-step explanation:
trust me dude i just took this question :D
For the answer to the question above,
<span>a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
c) Now use a = v² / r
where a was found above
and r was given
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given </span>
The two regular hexagons could have different side lengths, so they will not necessarily always be congruent, but they will always be similar.
Answer:
1.02×10¹ = 10.2
Step-by-step explanation:
We have given a number in scientific notation as follows 1.02×10¹
We need to convert it into standard notation.
1 is in ones place, 0 is in tenths place and 2 is in hundredths place.
So, the standard notation of 1.02×10¹ is 10.2
