Answer:

AC = 6 cm

Step-by-step explanation:

First, realize that these are two identical triangles. We just have to use the pythaogrean theorem on one side to find AD or DC, then multiply that by 2 to get AC.

a^2 + b^2 = c^2

8^2 + b^2 = 10^2

64 + b^2 = 100

100 - 64 = b^2

b^2 = 36

b = 6

Answer:

$P = 2(l+w)\\Length = 5x\\Width = 3x+7\\\\P = 2(5x +(3x+7))$

Step-by-step explanation:

Further Solving :

$P = 2(5x +(3x+7))\\P = 2(5x+3x+7)\\P = 2(8x+7)\\\\Perimeter = 16x + 14$

A relay microchip in a telecommunications satellite has a life expectancy that follows a normal distribution with a mean of 93 m

aliina [53]

The insurance period must be chosen so that the probability of a microchip failure within that period is 4%. Reference to a standard normal distribution table shows that the z-score for a cumulative probability of 4% is -1.75.
Let the insurance period be X months:
-1.75 = (X - 93)/3.8
-6.65 = X - 93
X = 83.35 months.
The answer is 83.35 months.
