Answer:
The height is 3.625ft.
Step-by-step explanation:
0.5x8xa=14.5
4a=14.5
a=14.5/4=3.625
The correct answer is n - 7 = 30
Answer:
5, 7 , 7 and 11.
Step-by-step explanation:
I don't quite understand the Romanian but I'm pretty sure you want to find the numbers whose Lowest Common Multiple is 385 and whose product is 2695. Find the factors of 2695:-
5 2695
7 539
7 77
11
2695 = 5*7*7*11.
Lowest common multiple = 5*7*11 = 385.
Answer:
250x + 525y ≤ 7800
no, 15 refrigerators and 8 pianos will not fit on the truck
Step-by-step explanation:
we know that x is the refrigerators and each one is 250 lbs
this can be written as 250x
we know that y is the pianos and each one is 525 lbs
this can be written as 525y
we also know that "no more than" is the same that as less than equal to
so this can be written as ≤
we can also say that the refrigerators and pianos has to be ≤ 7800
so now we have: 250x + 525y ≤ 7800
plug in 15 to x and 8 to y
250(15) + 525(8) ≤ 7800
3750 + 4200 ≤ 7800
7950 ≤ 7800
this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck
Answer:
800 ft
Step-by-step explanation:
2/3 minutes = 2/3 min * 60 sec/min = 40 sec = t
5 ft/sec = r
d= r * t = 5 ft/sec * 40 sec = 800 ft
