$189
If the discounted price is $210, and his friend gets a 10% discount on that price, you can divide 210/10 and get 21.
Rocco's friend gets a $21 discount on the $210 irons, so therefore he will be paying $189
Y=10x+20
10x because the price is $10 a class
+20 because it costs $20 for the monthly subscription
Answer:
288m^2
Step-by-step explanation:
ratio is 4000/3, though the thousand does not matter because we can just exchange units
18*4/3=24
24 meters
9*4/3=12
12 meters
24*12=288
Answer:
Step-by-step explanation:
mean=(88+72+85+76)/4=321/4=80.25
x |x-mean|
88 7.75 (88-80.25)
72 8.25 (80.25-72)
85 4.75 (85-80.25)
76 4.25 (80.25-76)

mean absolute deviation=25/4=6.25
Answer:
Answer is 2×c + log [10^{a} + 10^{b}] +a
Step-by-step explanation:
log 2 = a ,log 3 = b , log 7 = c
Using formula
<em>log d×e = log d + log e</em>
<em> log d^{a} = a×log d</em>
<em> log 5 = log [10^{a} + 10^{b}]</em>
log 490 in terms of a , b and c and you can have integer coefficients
log 490
= log 7^{2}×5×2
= 2×log 7 + log 5 + log 2
= 2×c + log [10^{a} + 10^{b}] +a
Answer is 2×c + log [10^{a} + 10^{b}] +a
