I need help ASAP help me plzzzzzz
anzhelika [568]
The answer is A because you need to find the unit rate of each cost
Since $2.80 is for 2 liters, do 2.80/2 which equals 1.4. So that’s the cost for one liter
Then, 6 half liter bottles is just 3 liters because 6*1/2= 3. Then to find the unit rate for that, do 3.90/3 which equals 1.3.
So the first option is $1.40 per liter and the second option is $1.30 per liter so the first option is more expensive- the 2-liter bottle, and the cost for that is 1.40
Hope this helps:))

An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $5990 and her st
GenaCL600 [577]

Answer: 14.38%

Step-by-step explanation:

Worth of stock in Company A = $5990

Percent decrease = 20%

New worth = $5990 - (20% × $5990)

= $5990 - (0.2 × $5990)

= $5990 - $1198

= $4972

Worth of stock in Company B = $2450

Percent decrease = 8%

New worth = $2450 - (8% × $2450)

= $2450 - (0.08 × $2450)

= $2450 - $196

= $2254

Previous total worth = $5990 + $2450

= $8440

Total worth = $4972 + $2254

= $7226

The total percentage decrease in the investor's stock account will be:

= [($8440 - $7226) / $8440] × 100

=( $1214 / $8440) × 100

= 0.1438 × 100

= 14.38%

Given vectors: p=2i-j, q=-i+j<br> find: 1. p+q<br> 2.p-q<br> 3. 2p-3q
otez555 [7]

Answer:

see explanation

Step-by-step explanation:

(1)

p + q

= 2i - j + i + j ← collect like terms

= 3i

(2)

p - q

= 2i - j - (i + j) ← distribute parenthesis by - 1

= 2i - j - i - j ← collect like terms

= i - 2j

(3)

2p - 3q

= 2(2i - j) - 3(i + j) ← distribute parenthesis

= 4i - 2j - 3i - 3j ← collect like terms

= i - 5j
