The Answer is: B.29
Because 6.5x4= 26 since it’s a triangle that is divided by 2 to get 13 once you finish the top half the bottom is a square 4x4=16 so 16+13=29
Remember that scientifc notation is always (number greater than or equal to 1 and less than 10) times 10^(number of decimal places moved to the right)
ok so remember htat whe multiplying you can assosiat the numbesr so we have (6.5)(10^-7)(4)(10^-4)=(6.5 times 4)(10^-7 times 10^-4)
also remember the exponential law that says
x^m times x^n=x^(m+n) so
10^-7 times 10^-4=10^(-7+-4)=10^-11
so now we have
6.5 times 4 times 10^-11
26 times 10^-11
26 needs to be more than 1 and less than 10
2.6 times 10^1 times 10^-11
combine the 10's
10^1 times 10^-11=10^(1+-11)=10^-10
2.6 times 10^-10
answer is 2.6 times 10^-10
51/17 = 3
If each bottle holds 17 ounces, then 3 bottles will hold 51 ounces.
The initial elevation of the seagull is at 15 3/8 feet. (+
15 3/8 feet)
The seagull then descended 23 1/6 feet to catch the fish.
(- 23 1/6 feet)
Therefore the elevation of the fish is:
elevation of fish = 15 3/8 – 23 1/6
elevation of fish = 123 / 8 – 139 / 6
<span>elevation of fish = - 374 / 48 = - 187 / 24 = - 7 19/24</span>
<span>
</span>
<span>negative sign means it is below sea level </span>
In ΔJKL
s = JK+KL+LJ/2
= 25+7+21/2
= 28
then,
ΔJKL = √[s(s-a)(s-b)(s-c)]
= √[28(28-25)(28-24)(28-7)
= √(28×3×4×21)
= √(7056
= 84cm²
Again,
ΔJKL = 1/2×JL×LK×∠L
or, 84 = 1/2×24×7×sin x°
or, 84/168 = sin x°
or, 1/2 = sin x°
or sin 30° = sin x°
or x° = 30°
At last,
∠K+∠L+∠J = 180° (sum of angle of triangle)
or, ∠K+30°+90° = 180°
or, ∠K = 180°- 120°
or, ∠K = 60°
