lianna [129]

Answer: 22

Step-by-step explanation:

The area of the picture =l×b = 20×16=320

The length of the frame is 16

If the width is x ( and it's uniform)

672- 320= 352

x=352/16

x = 22

The time period of a simple pendulum is directly related to the square root of its length. An 8 foot pendulum has a period of 3.

svp [43]

$T_1=k \sqrt{8}$

$T_2=k \sqrt{3}$

$\frac{T_2}{T_1} = \frac{T_2}{3.2} = \frac{ \sqrt{3} }{ \sqrt{8} }$

Then:

$T_2=3.2 \sqrt{ \frac{3}{8} } =1.96$ secs

Urgent help needed w/ right triangle trig

shusha [124]

Since this is a right triangle, you can use the main trig functions sin, cos, and tan. We must use sin for this problem because sin= opp/hyp. Plug in the numbers to this function. Sin (53) = a/25. Thus when you cross multiply, you get a= sin (53) x 25. When you plug it into a calculator the answer should come out to 19.97
