Answer:
$7.85
Step-by-step explanation:
given that price = $78.50
if sales tax percentage= 10% ,
amount she pays in taxes,
= sales tax percentage x price
= 10% x $78.50
= 0.1 x $78.50
= $7.85
Answer:
Gustavo
Step-by-step explanation:
if anything this looks like 38-19n, if the first term is n=1.
But as that isn't an option, gustavo should be correct, as his sequence would go down by 19 each time (yuki's would go up by 19 each time, not down like the sequence shows)
Step-by-step explanation:
first spinner:
5 is written once :1
total numbers: 13
formula: probability : occurrence of number/total numbers
probability : 1/13.
second spinner:
even numbers: 2,4,6,8,10,12
total : 6 numbers
total numbers: 13
with formula,
probability: 6/13
third spinner:
multiple of four: 4,8,12
total: 3
total numbers: 13
according to formula:
probability: 3/13.
Answer:
First ?: 4
Second ?: -6
Step-by-step explanation:
40-40=0, which leaves 4n left.
34-40=-6
The final answer would be n= 3/2.
The easiest way to do this is to work out f(-2) first, =-3(-2)+4=10, then find g(-2)=(-2)²=4.
(g*f)(-2)=4×10=40.
However, if g*f means g of f the answer is different, because having worked out that f(-2)=10 we put this result into g, so we find g(10)=10²=100.
So you need to determine whether g*f means g(x)×f(x) [answer 40] or g(f(x)) [answer 100] when x=-2.
