Answer:
He needs to buy 120 packages of dod food.
Step-by-step explanation:
b - bird food
h - hamster food
d - dog food
c - cat food
b + h + d + c = 600
b = h (bird food is the <em>same</em> as hamster food)
b = 4 d (bird food is <em>4 times</em> dod food)
c = d/2 (cat food is <em>half</em> dog food)
Total of packages ordered.
b + b + d + c = 600
4d + 4d + d + d/2 = 600
4 d + 4 d + d + d = 600. 2
10 d = 1.200
d= 120 .........the amount of dog food packages.
2 + (-20) + 8.....when sea level is 0.
starting on a platform 2 ft above sea level....so it is 2
dive down 20 ft....so this is below sea level...so it is -20
rise 8 ft...so it is 8
so ur answer is : 2nd answer choice
Answer:
He generates a random whole number from 1 to 3.
Step-by-step explanation:
Each winner has 3 possibilities, gets cotton candy, gets a shirt, or gets a keychain. We can asign each of this possibiltiies a number, 1 for cotton candy, 2 for the shirt and 3 for a keychain. So, for a simulation, its enough to take one of this whole numbers for each winner.
For an acute angled triangle
h^2 < x^2 + y^2 where h = longest side and x and y are the other 2 sides.
so here we have
15^2 < x^2 + (2x)^2
15^2 < 5x^2
x^2 > 15*3 = 45
x > sqrt 45 or x > 6.7
So smallest whole number value of x is 7
