Answer:
y = 2x +13
Step-by-step explanation:
when 2 lines are perpendicular, the product of the two gradients is -1
i.e. m x m1 = -1
so from 10y + 5x = 3, the gradient m is -0.5
m1 = -1 / -0.5 = 2
using m1 = 2 and pt(-7,-1),
the eqn is y = (m1)x +c
-1 = 2(-7) + c
c= 13
thus y = 2x +13
Answer:
$56
Step-by-step explanation:
The jacket is on sales for 30% off the original price = (0.3)
The original price (P) = $80
However, the expression "p - 0.3p" is to be used to find the sales price
The sale price = p - 0.3p
The sale price = $80 - 0.3($80)
The sale price = $80 - $24
The sale price = $56
Answer:
540 in³
Step-by-step explanation:
v = lwh
v = 18 * 10 * 3
c = 540 in³
Answer:
P (HHH) = 1/8
Step-by-step explanation:
We want the probability of HHH
P(HHH) = P (heads and Heads and heads)
When we have an and, we multiply the probability
P(heads 1st time) * p(heads 2nd time) * P (3rd time)
The probability of a heads is 1/2
1/2 * 1/2 * 1/2
P (HHH) = 1/8
Well for every ten packs Jason paid $16 ($64/4). If he charges his friend what he was charged, he would charge $16 for 10 packs :)
