Answer:

12.67 minutes

Step-by-step explanation:

Time taken is given by distance divided by speed

Given distance of 228, 000, 000 km and speed of light as 300, 000 km/s then time will be

Time=228, 000, 000/300, 000=760 seconds

Conversion

60 seconds make up 1 minute

760 seconds will be 760/60

Time=760/60=12.666666666666

Rounded off, this is 12.67 minutes

The average American man consumes 9.7 grams of sodium each day. Suppose that the sodium consumption of American men is normally
Phoenix [80]

Answer:

Step-by-step explanation:

b. p(10.5<x<11.2)= p(x<11.2)-p(x<10.5)

p(x<11.2)= (11.2-9.7)/1 = 1.5 = 0.9332

p(x<10.5)= (10.5-9.7)/1= .8= 0.7881

.9332-0.7881= .1451

c. 9.7-.253, 9.7+.253

9.447, 9.953

ABC with altitude \overline{BD}
just olya [345]

The length of \overline{AC} is given by the relationship between the similar triangles

ΔABD and ΔBDC.

  • \overline{AC} = <u>80</u>

Reasons:

The given parameters are;

The altitude of triangle ΔABD = \overline {BD}

The hypotenuse of formed right triangle = \overline {AC}

The length of AD = 8

Length of BD = 24

Whereby  ΔABD is a right triangle

We have;

ΔABD is similar to ΔBDC

Therefore, by similar triangle proportional sides relationship, we have;

\displaystyle \frac{\overline{AD}}{\overline{BD}}  = \mathbf{ \frac{\overline{BD}}{\overline{DC}}}

Which gives;

\overline{BD}^2 = \mathbf{\overline{DC} \times \overline{AD}}

Therefore;

\displaystyle \overline{DC} = \mathbf{\frac{\overline{BD}^2}{\overline {AD}}}

\displaystyle \overline{DC} = \frac{24^2}{8} = \mathbf{72}

\overline{AC} = \overline{DC} + \overline{AD}

Which gives;

\overline{AC} = 72 + 8 =\mathbf{ 80}
