Answer:

The scale factor is 1 to 1.3

Step-by-step explanation:

Here, we want to get the scale factor

To get the scale factor, we divide corresponding sides by each other

That, we have that

9/7 = 1.3

raketka [301]

Answer:

d = C - 2/3

Step-by-step explanation:

Subtract 2/3 from both sides of the equation:

C = d + 2/3

-2/3 -2/3

-----------------

C - 2/3 = d

A probability experiment is conducted in which the sample space of the experiment is S={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.

Snezhnost [94]

Answer:

The answer is " $\bold{\frac{2}{3}}$ "

Step-by-step explanation:

Given set:

$\to F \ or\ G = \{ 5,6,7,8,9,10,11,12\}$

In the above-given set, there are 8 elements and 12 possible outcomes so, the equation is:

$\to P( F\ or \ G) = \frac{8}{12}$

$= \frac{2}{3}$

by using the general addition Rule:

$\to P(F \cup G) = P(F) +P(G)- P(F \cap G)$

$=\frac{5}{12}+\frac{4}{12}- P(E \cap H)\\\\=\frac{6}{12}+\frac{3}{12}- \frac{1}{12}\\\\=\frac{6+3-1}{12}\\\\=\frac{8}{12}\\\\=\frac{2}{3}\\\\$

Two guy wires support a cell tower. Both guy wires touch the ground in the same place, 14.5 m away from the base of the tower. O

dalvyx [7]

Ok, so.

You first need to find the height of the shorts guy's setup. We know that the length of the base is 14.5, and that theta is 46 degrees. The opposite side equals tan46 * 14.5, which is 14.935. 14.935 is the height of the short guy's height. Now onto the other dude. We know that the height of his setup is 4.2 more than the shorts guy, which is equal to 19.13. Finally, to find the angle, theta, of the second guy, we take 19.13 / 14.5 and then take the inverse tangent of that number (1.31) which equals approximately 52.6 degrees.
