Answer:
She can travel 15 miles
Step-by-step explanation:
I first found my answer by adding 1.75 and 2.50 together
giving me 4.25
I then made the equation
4.25+ 1.05x = 20
Subtract 4.25 from both sides that leaves you with
1.05x = 15.75
divide 1.05x on both sides
x= 15 is your solution
The volume of a sphere is:
V=(4pr^3)/3 so the initial volumes is:
Vi=(4p*4.5^3)/3=121.5p in^3 (before match, approx 381.7 in^3)
Vf=(4p*4.4^3)/3=340.736p/3 (after match, approx 356.8 in^3
Vf-Vi=24.9 in^3
So the ball lost about 24.9 in^3 of air during the match...
This would be your answer 10x-8, x+8
Find the least common multiple of 8, 15, and 21. . . . . . It's 280 .
So all the numbers divisible by 8, 15, and 21 are all the multiples of 280.
The smallest 6-digit number is 100,000 .
100,000 / 280 = 357.1 , so the next whole-number multiple is the 358th one.
280 x 358 = <u>100,240</u> .
You can tell right away that this is the smallest one that qualifies,
because if you take away 280 and go to the next smaller multiple,
it won't have 6 digits anymore.
