Answer:
She is wrong
Step-by-step explanation:
in one gallon there is 128 ounces, and 2 would make it 256.
40 - 8 ounce cups would make it 320 ounces, therefore she would need 3 gallons at least.
Answer:
√308 or 17.5
Step-by-step explanation:
c^2=a^2+b^2
c^2-a^2=b^2
Substitute
18^2-4^2=b^2
324-16=b^2
b^2=308
b=√308 or b=17.5
I disagree. The first one is false. No exponent rules apply if the bases AND the exponents are different.
The second one is true. Bases are the sane so you add exponents. You get 3 to the -5 power. Written with positive exponents it’s 1/3 to the 5.
