Answer:
1 cookie = $1.25 1 cake = $15
Step-by-step explanation:
set up a system of equations:
let x = 1 cookie
let y = 1 cake
3x + 5y = 78.75
8x + 2y = 40
I multiplied the first equation by 2 to get: 6x + 10y = 157.50
I multiplied the second equation by -5 to get: -40x - 10y = -200.00
If you add both equations, the y-terms will be eliminated
-34x = -42.50
x = 1.25
Plug in 1.25 into equation to find value of y: 8(1.25) + 2y = 40
10 + 2y = 40
2y = 30
y = 15

Answer:
5√13 = c OR 18. 0
Step-by-step explanation:
Using the Pyhtagorean Theorem, we will solve for x (in this case our hypothenuse)
a2 + b2 = c2
10(square) + 15(square)= c2 .....10*10 = 100 and 15* 15= 225
100 + 225 = c2
325= c2
√325 = c
5√13 = c OR 18. 0
Answer:
I might be wrong i think its C but double check and dont put it in until you are sure its right

Answer:
6. Bacteria tend to grow very fast in a petri dish at first because of unlimited food and then begin to die out due
to competition. In a certain culture, the number of bacteria is givenby N(f) =1f +92t+.625' where /
represents the hours since 625 bac,teriawere introduced to the Petri dish. Determine the *={TlgX9"t
of bacteria that occur in the dish.
Step-by-step explanation:
t= -92/-2(2) =23
N (23) power 2 +92(23) + 625 =1628
