You want to find the time (x) when the distance from desitnation is 0:

d = 0,

d(x) = 1375 - 110x
0 = 1375 - 110x
110x = 1375
x = 1375/110
x = 12.5 hrs

What are the measurements of the little 2 small cube things on each side, better yet what's the surface area? Thank you

Arisa [49]

Answer:

166 units²

Step-by-step explanation:

We know that:

W = 7
L = 5
H = 4

Surface area is the area of the faces of the cuboid.

Work:

=> 2(7 x 4) + 2(5 x 4) + 2(5 x 7)
=> 2(28) + 2(20) + 2(35)
=> 56 + 40 + 70
=> 166 units²

Hence, Option C is correct.

Hoped this helped.

What is the probability that a daughter of this mating will be a hemophiliac? Express your answer as a fraction using the slash

schepotkina [342]

Answer:

zero (0)

Step-by-step explanation:

probability of being hemophiliac and daughter is zero because females have 50% chance of being carrier.

where as males have 50% chance of being affected with hemophilia.

example for understanding: if after mating a girl have X chromosomes with hemophilia gene than she might have hemophilia but that is in rear case so probability is zero.

hope you understand my answer, thank you.

Find the distance between the pair of points.

lana66690 [7]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 0 &,& -11~) 
% (c,d)
&&(~ -9 &,& -12~)
\end{array}
\\\\\\
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
d=\sqrt{[-9-0]^2+[-12-(-11)]^2}
\\\\\\
d=\sqrt{(-9-0)^2+(-12+11)^2}
\\\\\\
d=\sqrt{(-9)^2+(-1)^2}\implies d=\sqrt{82}$
