Algebraically:
13 + (38/60) + (35/3600) = 13. 6431 degrees
If you have a graphing calculator ( I am using a TI-84 plus Silver Edition):
13(press 2nd -> apps -> 1) 38 (press 2nd -> apps -> 2) 35 (press alpha -> +) = 13.6431
Answer:
about 7.6 days long
Step-by-step explanation:
42 divided by 5.52 = about 7.6
Answer:
- n + q = 25
- 0.05n + 0.25q = 4.05
Step-by-step explanation:
<em>Two equations</em> are required to represent this problem as posed.
1. An equation for the number of coins:
n + q = 25
2. An equation for the value of the coins:
0.05n + 0.25q = 4.05
Answer:
80 degrees.
Step-by-step explanation:
THe reason why the 3 angles add up to 180 degrees is because they are the 3 angles in the triangle.
So m APB = 180 - 100
= 80 degrees.
Answer:
28mph
Step-by-step explanation:
Let the speed at which Pat drives be xmph.
Now, we know John travels 32mph faster than Pat. Hence, John's speed is (x + 32)mph
The total distance is 440 miles.
Distance = Speed × Time
The distance traveled by each of them after 5 hours is given as follws;
Pat = 5 × x = 5x miles
John = 5(x + 32) miles
Now, if we add both distances, we get the total of 440 miles.
Hence, 5x + 5(x + 32) = 440
5x + 5x + 160 = 440
10x + 160 = 440
10x = 440 - 160 = 280
10x = 280
Hence, x = 280/10 = 28mph
