Answer:
1/3
Step-by-step explanation:
There are <u>four</u> 5's on the dial out of 12 possible stops
4/12 = 1/3 theoretical
1/6 + 3/6 = 4/6
= 2/3
= 0.6 recurring
= 0.6666666667
Answer:
a= 200
b = 210
Step-by-step explanation:
My assumption is, we have to find the length of sides of rectangle
Given
perimeter = 2a + 2b = 820 ft (i) (here a is smaller side and b is larger side)
area = a*b = 42,000 ft^2 (ii)
from eq (1)
2a + 2b = 820
=> 2(a+b) = 820
=> a+b = 820/2
=> a + b = 410
=> a = 410-b (iii)
putting the value of a in eq(ii), we get
(410-b) *b = 42,000
410b - b^2 = 42,000
0 = b^2 - 410b + 42000
b^2 - 410b + 42000 = 0
b^2- 200b- 210b + 42000 = 0
b(b-200)-210(b-200) = 0
(b-200)(b-210) = 0
or
b= 210 and b = 200
if b is larger side than b =210
By putting value of b in eq(iii),
a = 410 -210 = 200
68*x/100=48
=> 68*x=4800
=> x=4800/68
=> x~=70.58
P.S: * means multiply, ~= means approximation, / means divide
Answer
125 of each meal are ordered
Step-by-step explanation:
You first multiply 7 x 125, which will get you 875
Next, you multiply 5 x 125 and get 625
Add that together and you get 1500
