Answer:

One way to find the corresponding angles is to draw a letter F on the diagram. The letter F can also be facing the other way. In the above diagram, d and h are corresponding angles. The other corresponding pairs of angles in the above diagram are: b and f ; c and g ; a and e.

A grandfather clock’s pendulum has a period of 4.5 seconds. What is its frequency? Round to the nearest hundredth.

Brilliant_brown [7]

Answer: 0.22hz

Step-by-step explanation:

Hi to answer this question we have to analyze the information given:

<em>Period (T) = 4.5 Seconds </em>

So, to calculate the frequency of the pendulum we have to apply the formula;

Frequency (f)= 1 / period

Replacing with the value given:

f = 1/ 4.5 sec = 0.22 hz

Feel free to ask for more if needed or if you did not understand something.

Rafael Drive 405 miles using 20 gallons of gas. At that rate, how many gallons of gas would he need to drive 243 miles?

ANEK [815]

This is how I'd set it up:
405/20 = 243/x
this means the mpg (miles / gallons) for 1 situation is the same as the mpg for the other situation (because the rate is the same)
then just cross multiply and solve:
405x=243*20 or 405x=4860 or x = 12
he would need 12 gallons of gas for 243 miles

Simiplify.<br> U^2 - 4 / U^2 - 2u

Papessa [141]

Remember
difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)

and the undistributiv propeoryt
ab-ac=a(b-c)

so we have
$\frac{u^{2}-4}{u^{2}-2u}$
undistribute and factor
$\frac{(u-2)(u+2)}{u(u-2)}$
cancel out the one ( (u-2)/(u-2)=1)

$\frac{(u+2)}{u}$ is result
