Javier works in a photo lab and needs to make a reduced copy of a photograph that is 8 inches long. The customer wants the copy

Scrat [10]

Answer:

Javier should not press the button five time.

Step-by-step explanation:

The given scenario says that Javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. So, lets check that.

We will start at 8 inches.

Press once, $8-0.12*8=7.04$ inches.

Pressing again, we get $7.04-.12*7.04=6.1952$ inches.

Again pressing we get $6.1952-.12*6.1952 = 5.451776$ inches.

Again we get $5.451776-.12*5.451776 =4.79756288$ inches.

Again we get $4.79756288-.12*4.79756288= 4.221855334$ inches.

We can clearly see here that pressing 4 or 5 times does not get 4.5 inches exactly as claimed by Javier.

Therefore, Javier claim is not right and his boss is right.

Answer: f(y) x g(y) = 1

Step-by-step explanation:

$\frac{2y^3-y^2+2y-1}{y^3-y^2+y-1}\cdot \frac{2y^2-3y+1}{4y^2-4y+1}\\\\= \frac{4y^5-8y^4+9y^3-9y^2+5y-1}{4y^5-8y^4+9y^3-9y^2+5y-1} \\\\= \frac{(y-1)(2y-1)(2y-1)(y^2+1)}{(y-1)(2y-1)(2y-1)(y^2+1)} \\\\= 1$

a recipe calls for 12 ounces of raisin. raisins come in boxes of 170 g. how many boxes of raisins are needed for the recipe?

Olin [163]

Hi there! Hope this helps, and if it does, please mark brainliest!

Answer:

2 boxes

Step-by-step explanation:

There are roughly 28 grams in an ounce. So if you have 12 ounces, times 28 by 12, which is 336, so you need 336 grams of raisins. Divide by 170, the number of grams in one box, which would be 1.98 boxes, but you have to round up, so you would need two boxes.

Ellen works as a teller at a bank downtown. On Monday morning, Ellen left her house at 6:41 A.M. It took Ellen 10 minutes to wal

faltersainse [42]

The time that Ellen arrived at the bank was <u>7:02 A.M</u>.

Ordinarily, time is an ongoing and continuous sequence of events that occur in succession, from past through present, and to the future.

For our purpose, we can explain that time is a measure of years, months, weeks, days, hours, minutes, and seconds during which events occur.

Time is also a measure of the distance covered against the speed.

<h3>Data and Calculations:</h3>

The time Ellen left her house was 6:41 A.M.

The time Ellen took to walk to the subway = 10 minutes

Ellen reached the subway station at 6:51 A.M. (41 + 10)

The time that the subway ride took to reach the bank = 11 minutes

Therefore, Ellen arrived at the bank at 7:02 A.M. (51 + 11).

Thus, the time that Ellen arrived at the bank, where she works as a teller, was <u>7:02 A.M</u>.
