Jean drove 64 miles per hour for a total of 448 miles on a trip. She used the equation below to calculate the time, t, it would
Alexandra [31]

Answer:

Step-by-step explanation:

since there is no given formula I'm guessing that's what we want to find?

use the dist. = rate * time   formula for this kind of problem

or  d = r*t     ( this looks like the word  "dirt" to me so I call this the dirt formula partly b/c it's dirt simple, and it's generally about moving across some give dist. of dirt  :P )  

so Jean's rate is 64 MPH

her total distance is 448 miles  

rearrange the  d = rt  formula so that you are solving for the thing you don't know.. yet....   t (time)  for this case

soooo...

d/r = t

plug in number

448 / 64 = t

7 = t  (in hours)

The probability that an archer hits a target when he shoots an arrow is 0.7. The archer shoots two
Sholpan [36]

Answer:

The tree diagram is shown in the tree diagram is shown.

If the probability to hit is 0.7, then the probability to miss is 0.3.

P(hit, hit) = 0.7*0.7 = 0.49

P(hit, miss) = 0.7*0.3 = 0.21

P(miss, hit) = 0.3*0.7 = 0.21

P(miss, miss) = 0.3*0.3 = 0.09

Can I have some help?
lisabon 2012 [21]

Answer:

x =  \sqrt{58}

Step-by-step explanation:

first, you should draw a line to separate the triangle from the rectangle

You can get the height if the triangle by saying 16-9

This will give you 7

The base of the triangle is 3 because the opposite side is given and the opposite sides of a rectangle are equal

Now that we have the measurements of the triangle we can use the Pythagorean theorem

{c}^{2}  =  {a}^{2}  +   {b}^{2}

{x}^{2}  =  {7}^{2}  +  {3}^{2}

{x}^{2}  = 49+ 9

{x}^{2}  = 58

x =  \sqrt{58}
