two pages that are back-to-back in this book have 203 as the sum of their pages.what are the page numbers?

butalik [34]

2 pages back to back.....x and x + 1

x + x + 1 = 203
2x + 1 = 203
2x = 203 - 1
2x = 202
x = 202/2
x = 101

x + 1 = 101 + 1 = 102

the 2 page numbers are : 101 and 102

A point X is 34m due east of a point Y.The bearing of a flagpole from X and Y are N18W and N40E respectively calculate the dista

neonofarm [45]

Answer:

The answer is "38.130".

Step-by-step explanation:

Given:

$Points (Y, X) \\\\F (flagpole)\ make\ a \ triangle$

Draw Y and X triangles on the underside, and F above them.

Because F is $18^{\circ}$ west from X, so FXY angle measurement $FXY = 72^{\circ}$ from X because F is located $40^{\circ}$ east of north from Y, then

measure of angle $FYX = 50^{\circ}$

the measure of angle $YFX = 58^{\circ}$ $(3 \angle \ of\ triangle = 180^{\circ})$

Using Law of Sines: $\frac{\sine 58^{\circ}}{34} = \frac{\sine 72^{\circ}}{YF}$

Cross Multiply:

$YF (\sin 58^{\circ}) = 34(\sin 72^{\circ})\\\\$

$YF = \frac{34 \sin 72^{\circ}}{\sin 58^{\circ}}\\\\ YF = \frac{34(.951)}{(.848)}\\\\ YF = 38.130$

A train leaves at 14:56 and arrives at 16:43. It travelled at an average speed of 135 km/h. How far did it travel? Give your ans

Firlakuza [10]

Answer:

240.8

Step-by-step explanation:

→ Calculate time taken

16:43 - 14:56 = 1 hour and 47 minutes

→ Write the speed formula and make distance the subject

Speed = Distance ÷ Time ⇔ Distance = Speed × Time

→ Convert 1 hour and 47 minutes into decimal format

1.78333333 or $1\frac{47}{60}$

→ Substitute values into formula

135 × $1\frac{47}{60}$ = 240.75
