Answer:

There were total 2900 seats in the theater.

Step-by-step explanation:

Given that:

Seats filled by students = 1247 seats

Vacant seats = 57%

Total percentage of seats = 100%

Percentage of seats filled by students = (100-57)%

Percentage of seats filled by students = 43%

Let,

x be the total number of seats.

43% of x = 1247

[tex]\frac{43}{100}x=1247\\0.43x=1247[/tex]

Dividing both sides by 0.43

[tex]\frac{0.43x}{0.43}=\frac{1247}{0.43}\\x=2900[/tex]

Hence,

There were total 2900 seats in the theater.

Step-by-step explanation:

Significant figures are whole numbers, without any decimals, the four numbers are therefore significant.

Answer:

1/6, 2/3, 15/18

Step-by-step explanation:

get a common denominator

2/3 times 6

15/18 times 1

1/6 times 3

new fractions : 12/18, 15/18, 3/18

so it would be 3/18, 12/18, 15/18

then just revert it back to the original fraction and you have your answer

Answer:

60,000

Step-by-step explanation:

Jane-2000

Peter-ratio of 5=25000

Marta-ratio of 7=35000

25000+35000

60000

Answer:

$6,000

Step-by-step explanation:

If [tex]y[/tex] is the amount of money a child receives, and [tex]x[/tex] is the total amount being divided among the children, then

Jane's share:  [tex]y = \frac{4}{4+5+7} * x = \frac{4}{16}x[/tex]

Peter's share:  [tex]y = \frac{5}{4+5+7} * x = \frac{5}{16}x[/tex]

Martha's share:  [tex]y = \frac{7}{4+5+7} * x = \frac{7}{16}x[/tex]

We know Jane got $2000, so we can use that to solve for [tex]x[/tex]:

[tex]\frac{4}{16} x = 2000[/tex]

[tex]x = \frac{16}{4} * 2000 = 8000[/tex]

Plug this x value in to find how much Peter and Martha received:

[tex]\frac{5}{16} * 8000 + \frac{7}{16} * 8000 = $6000[/tex]

Integrate both sides with respect to t :

∫ dy/dt dt = ∫ -12t ² dt

y(t) = -4t ³ + C

Use the initial condition to solve for C :

5 = -4•0³+ C

C = 5

So

y(t) = -4t ³ + 5

and the answer is D.

Alternatively, you can directly apply the fundamental theorem of calculus:

[tex]\dfrac{\mathrm dy}{\mathrm dt}=-12t^2\implies y(t)=y(0)+\displaystyle\int_0^t -12u^2\,\mathrm du[/tex]

[tex]\implies y(t)=5-4u^3\bigg|_0^t[/tex]

[tex]\implies y(t)=5-4t^3[/tex]

Answer:

Each of the twin beds: 5 decorative pillows

Each of the queen beds: 11 decorative pillows

Step-by-step explanation:

Let the number of pillows used for each twin bed be x

Let the number of pillows used for each queen bed be y

she decorated 1 twin bed and 2 queen beds and used a total of 27 pillows. Thus;

x + 2y = 27 - - - (eq 1)

Also, she used

37 pillows to spruce up 3 twin beds and 2 queen beds. Thus;

3x + 2y = 37 - - - (eq 2)

From eq 1, x = 27 - 2y

Thus;

3(27 - 2y) + 2y = 37

81 - 6y + 2y = 37

81 - 4y = 37

4y = 81 - 37

4y = 44

y = 44/4

y = 11

x = 27 - 2(11)

x = 27 - 22

x = 5

Thus, she used 5 decorative pillows for each of the twin beds and 11 decorative pillows for each of the queen bed

Answer:

x < 6.8 or 34/5

Step-by-step explanation:

The parenthesis on the right side don't affect the inequality in any way so we can get rid of that.

5x – 6 < 2 + 30 – 4

Now we simplify the right side by combining like terms.

5x - 6 < 28

Our goal is to isolate x

Add 6 to both sides

5x < 34

Divide both sides by 5

x < 34/5

x < 6.8

Answer:

5×1=5

6×0.1=0.6

2×0.01=0.02

5×0.001=0.005

Step-by-step explanation:

Replace c with 50 and solve for f:

50 = 5/9(f-32)

Multiply both sides by 9:

450 = 5(f-32)

Distribute the right side:

450 = 5f -160

Add 160 to both sides:

610 = 5f

Divide both sides by5:

F =610/5

F = 122

Answer:

122 = F

Step-by-step explanation:

C = 5/9 ( F - 32)

Let C = 50

50 = 5/9 ( F - 32)

Multiply each side by 9/5

9/5 *50 = 9/5 *5/9 ( F - 32)

90 =  ( F - 32)

Add 32 to each side

90+32 = F -32+32

122 = F

Answer:

s + r - l

Step-by-step explanation:

This is an arithmetic progression question.

The formula to get the terms of an AP is;

L_n = a + (n - 1)d

Where;

a is first term

n is number of term

d is difference between terms

Thus, second term is;

L_2 = a + d

Third term is;

L_3 = a + (3 - 1)d

L_3 = a + 2d

Similarly, L_4 = a + 3d

Now we are told that;

Sum of the first 2 numbers is s;

Sum of the second and third number is l

Sum of the last two numbers is r

Thus;

a + (a + d) = s - - - (eq 1)

(a + d) + (a + 2d) = l - - - (eq 2)

(a + 2d) + (a + 3d) = r - - - (eq 3)

Thus, sum of the first and last term will be;

L_1 + L_4 = a + (a + 3d)

Now,from earlier;

(a + 2d) = r - (a + 3d)

Also;

(a + d) = s - a

Thus, plugging them into the eq 2 gives;

(s - a) + r - (a + 3d) = l

Expanding we have;

s + r - 2a - 3d = l

d = (s + r - 2a - l)/3

Thus;

L_1 + L_4 = a + (a + (3(s + r - 2a - l)/3))

= 2a + s + r - 2a - l = s + r - l

Answer:

Answer:

6 days

210 pages

Step-by-step explanation:

As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.

Now since he reads 35 pages per day.

Then mathematically;

y = 35x

For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)

To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that

Also; y = 30(x + 1)

Equating the two situations

35x = 30(x + 1)

35x = 30x + 30

35x -30x = 30

5x = 30

x = 30/5

x = 6 days

This means that it will take Amir 6 days to catch Jese.

The number of books they would have read by then is y = 35x = 30(x + 1)

= 35 * 6 or 30(6+1)

= 210

Step-by-step explanation:

Answer: dude above me copied

Step-by-step explanation:

1. y = 35x

2. y = 30x + 1

3. y = 35x

   y = 30 x + 1

4. Its more convenient to substitute y because It's easier.

    35x = 30(x + 1)

5.  35x = 30x + 1

    35x = 30x + 30

    35x -30x = 30

    5x = 30

    x = 6    (30/5 = 6)

    35 x 6 = 210 (y)

6. Both people have read 210 pages and it takes amir 6 days to catch up.

|-3.75| is greater than |-2.4|

A number system is defined as a system of writing to express numbers.

We need to find which number is greater than |-2.4| in the given options.

We know that the absolute value of |-2.4| is always positive.

The value of |-2.4|  is 2.4.

Now we need to check which number is greater than 2.4.

In option A it is -6.3 which is negative. so it is not our answer.

Even in option B the value is negative so it is also not correct.

In option C we have |-3.75|. The value of |-3.75| is 3.75 because it is in mod which we consider as positive.

As 3.75 is greater than 2.4. so out answer will be |-3.75|

Hence, |-3.75| is greater than |-2.4|

Answer:

D) 32

Step-by-step explanation:

Given;

series: 56, 54, 50, 38, 34, ....

find the difference between successive numbers;

56         54        50             38            34             x

     2            4             12              4             2            

The highest difference between the numbers is  12, after which it decreases to 4 and finally back 2.

The next number "x" is calculated as;

34 - 2  = x

34 - 2 = x

32 = x

Therefore, the next number should be 32.

The next number that should come next in the series is 32.

Sequence is an arrangement of two or more things in a successive order.  Series is the cumulative sum of a given sequence of terms.

Given the numbers in the series: 56, 54, 50, 38, 34, . . ..

The difference is 2, 4, 12, 4, 2

The highest difference between the numbers is  12, after which it decreases to 4 and finally back 2. Hence:

The next number = 34 - 2 = 32

The next number that should come next in the series is 32.

Answer:

82.88%

Step-by-step explanation:

Given that:

Mean (μ) = 16.7 pounds

Standard deviation (σ) = 3.8 pounds

Number of pounds eaten = 11.5 = x

P(11.5 ≥ x ≤11.5)

P(x ≤ 11.5) :

Zscore = (x - μ) / σ

Zscore = (11.5 - 16.7) / 3.8

Zscore = - 5. 2 / 3.8

Zscore = −1.368421

P(Z ≤ - 1.3684) = 0.085593 (Z probability calculator)

P(x ≥ 11.5) ;

Zscore = (x - μ) / σ

Zscore = (11.5 - 16.7) / 3.8

Zscore = - 5. 2 / 3.8

Zscore = −1.368421

P(Z ≥ - 1.3684) = 0.91441 (Z probability calculator)

P(Z ≥ - 1.3684) - P(Z ≤ - 1.3684)

0.91441 - 0.085593 = 0.828817
