Answer:

50 for $4.75

Step-by-step explanation:

First step is to determine the unit cost of each pencil:

price of pack / number of units = cost per pencil

1. $2.19 / 12 = $0.1825

2. $3.99 / 40 = $0.09975

3. $4.75/ 50 = $0.095

4. $10 / 100 = $0.10

The correct answer is $4.75 for 50 pencils because it is the lowest per unit cost.

If m∠NOP = 24° and m∠NOQ = 110°, what is m∠POQ?
andrew11 [14]

Correct answer for the above question is - option B. 86°

<u>Step-by-step explanation:</u>

Given:

∠NOP = 24°

∠NOQ = 110°

∠NOP and ∠POQ are adjacent angles

To Find:

∠POQ = ?

Solution:

Hereby, we can say that ∠POQ lies between line OQ and ON as given (∠NOP and ∠POQ are adjacent angles )

∠NOQ - ∠NOP = ∠POQ

∠POQ = 110° - 24°

<u>∠POQ = 86°</u>

Angle POQ is  86°

Thus we can conclude option B as correct answer.

If y varies directly as x, and y=6 as x=-1, find y for the x-value of 5
Tema [17]

Answer:

y=-30

Step-by-step explanation:

we are given

y varies directly as x

so, we can write equation as

y=kx

where

k is constant of proportionality

We have

at x=-1 , y=6

so, we can use it to find k

6=k(-1)

so, we get

k=-6

now, we can plug it back

y=-6x

now, we can plug x=5

and we get

y=-6\times 5

y=-30
