Answer:
A 65
Step-by-step explanation:
The angle formed by two chords is 1/2 the sum of intercepted arcs
x = 1/2 (51+79)
x = 1/2(130)
x =65
Answer:
Step-by-step explanation:
Let the speed of the car is c and speed of the plane is p.
<h3>We are given:</h3>
The speed of the plane is 7 times the speed of the car
The distance traveled is
The time difference to travel this same distance is 3 hours.
<h3>We know that:</h3>
- d = ts, where d- distance, t- time, s - speed
Find the time for car and plane and their difference.
<h3>Car</h3>
<h3 /><h3>Plane</h3>
- t = d/s = 315/p = 315/(7c) = 35/c
<h3 /><h3>The difference</h3>
<u>Solve it for c:</u>
- (315 - 45)/c = 3
- 270/c = 3
- c = 270/3
- c = 90 km/h
Now find the speed of plane:
As we see, Jenny is right
Answer:the answer is the first
Step-by-step explanation:
Because the expression can be written as -10r2/2r2+4+5r/2r2+4+3/2r2+4
Using proportions, it is found that his DAILY RATE on that particular day is of Php 2,420
.
- This question is solved by proportions, using a <em>rule of three.</em>
- In a regular 8-hour day, Allen earns Php 1420. How much will he earn on a 14 hour day?
The <em>rule of three</em> is:
8 hours - Php 1420
14 hours - x
Applying cross multiplication:



The closest option is Php 2,420.
