Answer:
The constant speed with Ed is travelling is 60 mile per hour
Step-by-step explanation:
Given as :
The distance cover to travel from Jefferson to Holden is (D1) 250 miles
The distance cover to travel from Holden to Paxton is (D2) 50 miles
Total time taken to complete entire journey = T = 5 hours
Let The constant speed of Ed = S mph
Time =
Or, Time =
+
Or, 5 hour =
+
Or, 5 × S = 250 + 50
So, 5 × S = 300
∴ S =
I.e S = 60 mph
Hence , The constant speed with Ed is travelling is 60 mile per hour Answer
Answer:
C
Step-by-step explanation:
It is not E becuase SQRT(97) is less than SQRT(100), SQRT(100) is 10,
SQRT(81) is 9 SO SQRT(97) is between 9 and 10, C.
Hope it helps :)
Answer:
Soccer
Step-by-step explanation:
Alright, lets say the measure of the 3rd angle (the smallest one) is x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.
(x + 25) + 3x + x = 180
5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)
31 + 25 = 56o (first angle)
3 × 31 = 93o (second angle)
56 + 93 + 31 = 180
Answer:
Number of children = 386
Number of adults = 287
Step-by-step explanation:
Let
x = number of children
y = number of adults
x + y = 673 (1)
1.75x + 2y = 1249.50 (2)
From (1)
x = 673 - y
Substitute x = 673 - y into (2)
1.75x + 2y = 1249.50
1.75(673 - y) + 2y = 1249.50
1177.75 - 1.75y + 2y = 1249.50
- 1.75y + 2y = 1249.50 - 1177.75
0.25y = 71.75
y = 71.75/0.25
y = 287
Substitute y = 287 into (1)
x + y = 673
x + 287 = 673
x = 673 - 287
x = 386
Number of children = 386
Number of adults = 287
