Answer:

the larger of two printers being used to print the payroll for a major corporation requres 40 min. to print the payroll.So the smaller printer's payroll printing rate is

1 payroll per x min or or

>>...After both printers have been operating for 10 min, the larger printer malfunctions...<<

So the fraction of the payroll that the larger printer did in the 10 minutes

is = payroll.

After reading a book foe English class, 100 students were asked whether or not they enjoyed it. Nine twenty-fifths of the class

Katena32 [7]

Answer:

The number of students who liked the book was 64.

Step-by-step explanation:

After reading a book for English class, 100 students were asked whether or not they enjoyed it.

Now, given that nine twenty-fifths of the class did not like the book.

So, $\frac{9}{25}$ of the whole class did not like the book.

Then, the fraction of the class who did like the book was $(1 - \frac{9}{25}) = \frac{16}{25}$ .

Therefore, the number of students who liked the book was $(100 \times \frac{16}{25}) = 64$ . (Answer)

Does anybody know the answer to these questions?

Answer:

1. 625,000 J

2. 100 J

4. 5 kg

5. √5 ≈ 2.236 m/s

Step-by-step explanation:

You should be aware that the SI derived units of Joules are equivalent to kg·m²/s².

To reduce confusion between m for mass and m for meters, we'll use an italic m for mass.

In each case, the "find" variable is what's left after we put the numbers into the formula. It is what the question is asking for. The "given" values are the ones in the problem statement and are the values we put into the formula. The formula is the same in every case.

1. KE = (1/2)mv² = (1/2)(2000 kg)(25 m/s)² = 625,000 kg·m²/s² = 625,000 J

2. KE = (1/2)mv² = (1/2)(0.5 kg)(20 m/s)² = 100 kg·m²/s² = 100 J

4. KE = (1/2)mv²

250 J = (1/2)m(10 m/s)² = 50 m²/s²

(250 kg·m²/s²)/(50 m²/s²) = m = 5 kg

5. KE = (1/2)mv²

2000 kg·m²/s² = (1/2)(800 kg)v²

(2000 kg·m²/s²)/(400 kg) = v² = 5 m²/s²

v = √5 m/s ≈ 2.236 m/s

AlexFokin [52]

Answer:

96 * 144 - 168 * 42

Step-by-step explanation:

So the area of the wall is 96 * 144

And the area of the tiled part is 168 * 42

So it would be 96 * 144 - 168 * 42

I need to collect 30 stickers. Each bag of crisps contains 3 stickers. How many bags will I need to buy?

soldier1979 [14.2K]

Hey there :)

Let p represent the number of bags to be bought

We need to collect 30 stickers and each bag has 3 stickers

3p = 30
↑ ↑
Number of stickers in a bad Number of stickers to be collected

$\frac{3p}{3}$ = $\frac{30}{3}$
p = 10

We need to buy 10 bags of crisps to have 30 stickers
