Answer:
a. The price per ticket is 4 bucks, and b. you get 1/4 of a ticket for a dollar.
1. the penguin walks 75 feet in 45 seconds, and 2. it takes 27 seconds to walk 45 feet.
Step-by-step explanation:
Tickets:
16 dollars divided by 4 tickets is 4 dollars, so 4 dollars = 1 ticket. therefore, 1 dollar gives you 1/4 of a ticket.
Penguins
formula: X = feet, Y = seconds
X*0.6=Y
10 feet*0.6=6 seconds
(?) feet*0.6= 45 seconds
75 feet*0.6=45 seconds
same thing, but backwards this time
45 feet*0.6=(?) seconds
45 feet*0.6= 27 seconds
Hey can I have brainly please I am really close to leveling up
thx
Answer:
$4.00
Step-by-step explanation:
Mark down it by 25% three times will be 75%, so when you multiply the two, it becomes 75%. do 16/4 to get the reduction for 25%,, and you get 12. Then dive it by for 2 more times to get $4
(f - g)(x) = f(x) - g(x)
(f - g)(x) = ( f(x) ) - ( g(x) )
(f - g)(x) = (4x^2 - 6) - ( x^2 - 4x - 8)
(f - g)(x) = 4x^2 - 6 - x^2 + 4x + 8
(f - g)(x) = (4x^2-x^2) + 4x + (-6+8)
(f - g)(x) = 3x^2 + 4x + 2
<h3>Answer: Choice D</h3>
Each ounce of egg contains 40 milligrams of protein and 20 milligrams of vitamin B. Each ounce of fish contains 50 milligrams of protein and 10 milligrams of vitamin B
Needs 580 and 200
280 140
300 60
so, 7 eggs 6 fish
Answer:
37° and 53° respectively.
Step-by-step explanation:
We need to know that the angles are complementtary if ∠RSU + ∠UST = 90°. Then,
5x+7 + 9x-1 = 90
5x + 9x +7 -1 = 90
14x +6 = 90
14x = 90 - 6
14x = 84
x = 84/14
x = 6.
Then, the angle ∠RSU has measure 5(6)+ 7 = 30+7 = 37, and the angle ∠UST has measure 9(6) - 1 = 54-1 = 53.
