Answer:

Step-by-step explanation:

Mathematically, if two triangles are similar, then all the three of their angles are congruent to each other and their corresponding sides are in the same proportion. This means that the ratio of their corresponding sides are equal to each other.

Answer: A trigonometric table will provide all the angles in respect to the ratios of the sides.

Step-by-step explanation:

A trigonometric table would provide all of the ratios of the sides in respect to the angles. Sin, cos, and tan are parts of trigonometric table.

Trigonometry table, tabulated values for some or all of the six trigonometric functions for various angular values.

Since the ratios for sides of triangles are the same, when the angles are the same, trigonometric tables have been developed which show these ratios for every angle.

The​ time, t, required to drive a fixed distance varies inversely as the​ speed, r. It takes 8 hr at a speed of 15 ​km/h to driv
loris [4]

Answer:

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding decrease in the other variable. Also, a decrease in the value of one variable would cause a corresponding increase in the other variable.

The​ time, t, required to drive a fixed distance varies inversely as the​ speed, r. By introducing a constant of variation, k(the fixed distance), the expression becomes

t = k/r

It takes 8 hr at a speed of 15 ​km/h to drive a fixed distance. It means that

8 = k/15

k = 8 × 15 = 120

The equation becomes

t = 120/r

Therefore, the time it will take to drive the same distance at a speed of 29 ​km/h is

t = 120/29 hours

Converting to minutes, it becomes

120/29 × 60

= 248. 28 minutes

248 minutes, 28 seconds

Answer:

XZ=12 in

Step-by-step explanation:

area of a rhombus is A=pq/2

where p=WY=15.5 and A=93 and q=XZ

93=15.5(XZ)/2

93(2)=15.5(XZ)

186/15.5=XZ

XZ=12 in

Marco has a collection of 38 state quarters. If 3/5 of his quarters are dated 2005, what is the approximate value of the quarter
Kipish [7]
First, find the number of quarters that are dated 2005 by multiplying 38*(3/5)
You get 22.8, so you round that to the nearest whole number (23)
Then, since each quarter is worth ($.25) you multiply the number of coins by the worth.
23*.25=$5.75
