22.11 divided by 11?

Mathematics

1 answer:

Dimas [21]3 years ago

5 0

Answer: 2.01

Explanation: I rounded 22.11 two 22. So when you divide it by eleven is 2. Then you divide 11 by 11. Which is one, and it seems it was in the hundreths place so you add a cero before the one.

Answer:

<u>The Springfield Movie Theater last Thursday sold 65 adult tickets and 24 children's tickets.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the problem correctly:

Price of adult ticket = US$ 4.10

Price of children ticket = US$ 2.70

Last Thursday total collection = US$ 331.30

Total movie watchers = 89

Number of adults = x

Number of children = y

2. How many of each type of ticket were sold on Thursday?

Let's build our equations system to answer the question, this way:

x + y = 89

4.10x + 2.70y = 331.30

Solving for x on the 1st equation:

x + y = 89

x = 89 - y

Replacing x on the 2nd equation and solving for y:

4.10x + 2.70y = 331.30

4.10 (89 - y) + 2.70y = 331.30

364.90 - 4.10y + 2.70y = 331.30

-1.40y = 331.30 - 364.90

-1.40y = - 33.60

y = -33.60/-1.40

y = 24

Solving for x:

x + y = 89

x + 24 = 89

x = 89 - 24

x = 65

Proof of x = 65 and y = 24

4.10x + 2.70y = 331.30

4.10 * 65 + 2.70 * 24 = 331.30

266.50 + 64.80 = 331.30

331.30 = 331.30

We proved that x = 65 and y = 24 are correct

Mr. Sanchez’s class sold fruit pies for $1.32 each and Mr. Kelly’s class sold bottles of fruit juice for $1.77 each. Together, t

aleksklad [387]

Answer:

Part a)

The quantity of fruit pies sold was $42$

The quantity of juice bottles sold was $48$

Part b) Mr. Kelly’s class earned more money

part c) $\$29.52$

Step-by-step explanation:

Part a)

Let

x-----> quantity of fruit pies sold

y----> quantity of juice bottles sold

we know that

$x+y=90$

$x=90-y$ -----> equation A

$1.32x+1.77y=140.40$ ----> equation B

substitute equation A in equation B

$1.32(90-y)+1.77y=140.40$

$118.8-1.32y+1.77y=140.40$

$0.45y=140.40-118.8$

$0.45y=21.6$

$y=48$ bottles of fruit juice

Find the value of x

$x=90-y$ ------> $x=90-48=42$ fruit pies

Part b) Which class earned more money?

Mr. Sanchez’s class

$\$1.32x=1.32*42=\$55.44$

Mr. Kelly’s class

$\$1.77y=1.77*48=\$84.96$

therefore

Mr. Kelly’s class earned more money

Part c) How much more money did that class earn?

Find the difference

$\$84.96-\$55.44=\$29.52$

For the following system, determine if a steady state exists and give the steady state value. The population of a colony of squi

Anettt [7]

Answer:

Option A)

$\displaystyle\lim_{t\to\infty}~p(t) = k$

Step-by-step explanation:

We are given the following on the question:

$p(t) =\displaystyle\frac{4000}{4+e^{-0.02t}}$

where p(t) is the population of a colony.

For steady state solution we evaluate:

$\displaystyle\lim_{t\to\infty}~p(t)\\\\= \lim_{x\to\infty} \frac{4000}{4+e^{-0.02t}}\\\\=\frac{4000}{4+e^{-\infty}}\\\\=\frac{4000}{4}\\\\= 1000$

Thus, the steady state solution is a constant, k = 1000.

Thus, the correct answer is

Option A)

$\displaystyle\lim_{t\to\infty}~p(t) = k$

What is the relationship between the following ordered pairs 0,6 2,5 4,4 and 6,3 keep in mind it will be a two step process

aliya0001 [1]

Find the first rate of change...

(5-6)/(2-0)=(4-5)/(4-2)=(3-4)/6-4)=-1/2

So this equation has a constant velocity which means that it is linear and can be expressed as y=mx+b where m=slope=velocity and b=y-intercept, value of y when x=0...we saw earlier that the velocity or slope is -1/2 so:

y=-x/2+b, and we can use any point to solve for b, I'll use (6,3)

3=-6/3+b

3=-2+b

b=5

So the relationship if the function:

y=-x/2+5 or more neatly...

y=(10-x)/2

Can someone help. I’m having trouble with the equation part

mote1985 [20]

Answer:

(x+3) x+7 is the answer for the first question if it's the same way my school does it. Whatever you put in parentheses is the opposite of what you think. + is going to the left. - is going to the right but those only apply when in parentheses.
