Alright, I don't know what your choices are, but here's my input:
For a line to be perpendicular to another line, the slope needs to be the opposite reciprocal of the slope of the given line. Now, by opposite, I mean if your slope is positive, this one needs to be negative (or vice versa). For reciprocal, I mean flip the fraction over. In this case, we have a slope of 2, so its opposite is -2 & the reciprocal is -1/2. So, whatever line has a slope of -1/2 is your answer.

Hope this helps!

The average price of a gallon of milk is $3.31. If the price increases .88% each year , how much will a gallon of milk cost in 2
musickatia [10]

Answer:

$3.94

Step-by-step explanation:

You will need to use the compound interest formula for this.

P(1+\frac{r}{n} )^{nt}

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

Your equation will look like this:

3.31(1+\frac{.0088}{1} )^{20} = 3.94

Jerry King is a server in a restaurant that pays a salary of $43 per day. He also averages tips of 18% of his total gross food o
tatyana61 [14]

Answer:

His total gross pay for the week is $588.25.

Step-by-step explanation:

Consider the provided information.

Jarry has a salary of $43 per day and he worked for 4 days.

Thus, the salary of 4 days is:

4 × $43= $172

The average tips is 18% of his total gross food orders.

Last week he had total food orders of $2,312.5. Therefore, the total tips he received is:

2312.5 \times(\frac{18}{100})

2312.5 \times(0.18)

416.25

Total tips he received is $416.25.

His total gross pay for the week = The salary of 4 days + Total tips he received.

His total gross pay for the week = $172 + $416.25

His total gross pay for the week = $588.25

Hence, his total gross pay for the week is $588.25.

Can you help me please!!!!

If you add the 3/4s with the 2 1/4 hour breaks it would be 1 hour and 1 fourth.
Then you take 10-1/2 hours and subtract it by 1 hour and 1 fourth.
So you would get 9-1/4 hours
