Answer:
the answer is 8 oz
Step-by-step explanation:
well it says for the first ounce is $0.49 so $0.49 is your first number, then you're trying to figure out how many $.21
2.then to make this easier you subtract $0.49 from $1.96 and that's is $1.47
3.then all you need to do is divide $1.47 By .21 cents anand you should get 7 .
4.but don't forget the $0.49 for the first ounce ,then 1 ounce add it to the 7 and It will equal 8 oz in total
Answer:
(x +9) ^2 + (y +7)^2 = 289
Step-by-step explanation:
We know the equation of a circle can be written as
(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
We are given the diameter so we can find the radius
r = d/2 = 34/2 = 17
(x- -9) ^2 + (y- -7)^2 = 17^2
(x +9) ^2 + (y +7)^2 = 17^2
(x +9) ^2 + (y +7)^2 = 289
Answer:
answer will be -2j+11k
expln: 4v+3w
=4(3i-2j+5k)+3(-4i+2j-3k)
=12i-8j+20k-12i+6j-9k
=(12-12)i+(-8+6)j+(20-9)k
= -2j+11k :)
