Step-by-step explanation:

Answer:

3,900 – 2,200

Step-by-step explanation:

Given that,

In September, 2,209 people visited the museum.

In June, the number of visitors to the museum grew to 3,897.

2209 can be rounded off as 2200 to the nearest hundred place.

3,897 can be rounded off as 3900 to the nearest hundred place.

The required answer is :

3,900 – 2,200 = 1700

Hence, the correct option is (c).

Answer:

I believe that it is the 2nd option x(x-1)/2 but I could be wrong sorry if I am

Answer:

Assuming you mean from $60 to $45, that would be 25%.

Step-by-step explanation:

We can use the simple formula: [tex]\frac{NEW-OLD}{OLD} *100[/tex]

In this case: [tex]\frac{45-60}{60} *100 = -25[/tex]

Which means there is a 25% discount.

Answer:

The 5 unknown are 1 quarter, 3 dimes, and 1 penny.

Answer:

One penny

One nickel

Five dimes

One quarter total

Step-by-step explanation:

81 - 25(coins we know) = 56 cents left

So we know we need 1 penny

Then 4 coins make up 55 cents, so that's a quarter & 3 dimes

Answer:

[tex]P(Same\ Bill) = \frac{1}{3}[/tex]

[tex]P(Second<First\ Bill) = \frac{1}{3}[/tex]

[tex]P(Both\ Even) = \frac{1}{9}[/tex]

[tex]Pr(One\ Odd) = \frac{4}{9}[/tex]

[tex]P(Sum < 10) = \frac{1}{3}[/tex]

Step-by-step explanation:

Given

[tex]Bills: \$1, \$5, \$10[/tex]

[tex]Selection = 2\ bills[/tex]

The sample space is as follows:

This implies that we construct possible outcome that Ebony selects a bill, returns the bill and then select another.

This means that there are possibilities that the same bill is selected twice.

So, the sample space is as follows:

[tex]S = \{(1,1), (1,5), (1,10), (5,1), (5,5), (5,10), (10,1), (10,5), (10,10)\}[/tex]

[tex]n(S) = 9[/tex]

Solving (a): [tex]P(Same\ Bill)[/tex]

This means that the first and second bill selected are the same.

The outcome of this are:

[tex]Same = \{(1,1),(5,5),(10,10)\}[/tex]

[tex]n(Same\ Bill) = 3[/tex]

The probability is:

[tex]P(Same\ Bill) = \frac{n(Same\ Bill)}{n(S)}[/tex]

[tex]P(Same\ Bill) = \frac{3}{9}[/tex]

[tex]P(Same\ Bill) = \frac{1}{3}[/tex]

Solving (a): [tex]P(Second < First\ Bill)[/tex]

This means that the second bill selected is less than the first.

The outcome of this are:

[tex]Second < First = \{(1,5), (1,10), (5,10)\}[/tex]

[tex]n(Second < First) = 3[/tex]

The probability is:

[tex]P(Second<First\ Bill) = \frac{n(Second<First\ Bill)}{n(S)}[/tex]

[tex]P(Second<First\ Bill) = \frac{3}{9}[/tex]

[tex]P(Second<First\ Bill) = \frac{1}{3}[/tex]

Solving (c): [tex]P(Both\ Even)[/tex]

This means that the first and the second bill are even

The outcome of this are:

[tex]Both\ Even = \{(10,10)\}[/tex]

[tex]n(Both\ Even) = 1[/tex]

The probability is:

[tex]P(Both\ Even) = \frac{n(Both\ Even)}{n(S)}[/tex]

[tex]P(Both\ Even) = \frac{1}{9}[/tex]

Solving (e): [tex]P(Sum < 10)[/tex]

This question has missing details.

The correct question is to determine the probability that, the sum of both bills is less than 10

The outcome of this are:

[tex]One\ Odd = \{(1,10), (5,10), (10,1), (10,5)\}[/tex]

[tex]n(One\ Odd) = 4[/tex]

The probability is:

[tex]Pr(One\ Odd) = \frac{n(One\ Odd)}{n(S)}[/tex]

[tex]Pr(One\ Odd) = \frac{4}{9}[/tex]

Solving (d): [tex]P(One\ Odd)[/tex]

This question has missing details.

The correct question is to determine the probability that, exactly one of the bills is 0dd

The outcome of this are:

[tex]Sum < 10 = \{(1,1), (1,5), (5,1)\}[/tex]

[tex]n(Sum < 10) = 3[/tex]

The probability is:

[tex]P(Sum < 10) = \frac{n(Sum < 10)}{n(S)}[/tex]

[tex]P(Sum < 10) = \frac{3}{9}[/tex]

[tex]P(Sum < 10) = \frac{1}{3}[/tex]

Which group forms a rectangle of

[tex]Length = 15[/tex]

[tex]Width = 11[/tex]

First, calculate the area of the big rectangle

[tex]Area = Length * Width[/tex]

[tex]A_{Big} = 15 * 11[/tex]

[tex]A_{Big} = 165[/tex]

Next, calculate the area of each rectangle A to E.

[tex]A_A = 11 * 7[/tex]

[tex]A_A = 77[/tex]

[tex]A_B = 2 * 11[/tex]

[tex]A_B = 22[/tex]

[tex]A_C = 6 * 6[/tex]

[tex]A_C = 36[/tex]

[tex]A_D = 6 * 5[/tex]

[tex]A_D = 30[/tex]

[tex]A_E = 13 * 4[/tex]

[tex]A_E = 52[/tex]

Then consider each option.

(a) 3E + 2B

[tex]3E + 2B = 3 * 52 + 2 * 22[/tex]

[tex]3E + 2B = 156 + 44[/tex]

[tex]3E + 2B = 200[/tex]

(b) A + B + C + D

[tex]A + B + C + D = 77+22+36+30[/tex]

[tex]A + B + C + D = 165[/tex]

(c) 2C + 2D + 2B

[tex]2C + 2D + 2B = 2 * 36 + 2 * 30 + 2 * 22[/tex]

[tex]2C + 2D + 2B = 72 + 60 + 44[/tex]

[tex]2C + 2D + 2B = 176[/tex]

(d) A + 4B

[tex]A + 4B = 77 + 4 * 22[/tex]

[tex]A + 4B = 77 + 88[/tex]

[tex]A + 4B = 165[/tex]

(e) E + C + D + 3B

[tex]E + C + D + 3B = 52 + 36 + 30 + 3 * 22[/tex]

[tex]E + C + D + 3B = 52 + 36 + 30 + 66[/tex]

[tex]E + C + D + 3B = 184[/tex]

Recall that:

[tex]A_{Big} = 165[/tex]

Only options (b) and (d) match this value.

[tex]A + B + C + D = 165[/tex]

[tex]A + 4B = 165[/tex]

Hence, options (b) and (d) are correct

Answer: It's 14

Step-by-step explanation:

Okay, so we need to follow PEMDAS, or Parenthesis, Exponents, Multiplication and Division, Addition and Subtraction. First we solve what's in the parenthesis. 4 plus 3 is 7. There are no exponents, but there IS multiplication. Whenever you see a number next to an expression inside parenthesis, it always means multiply. In this case we're multiplying 4 plus 3, which is 7, by 2. So 7 times 2 is 14.

Answer:

Step-by-step explanation:

40/100 x 45 = 2/5 x 45 = 18

Answer: 18

Step-by-step explanation:

To find the number of times out of 45 Evelyn is on time for class, we need to find 40 percent of 45. 40 percent of 45 is equivalent to writing 0.4 x 45. Since 0.4 x 45 equals 18, we can estimate that Evelyn will be on time to class about 18 times out of 45

Answer:

Cubes have 6 equal faces, and the surface area is the sum of all of these faces. Thus, one face would be 1/6 of the cube's surface area, or about 17%.

Step-by-step explanation:

Answer:

9.V=480

10.V=25.1

11.V=377

12.V=160

13.V=179.6

14.V=452.4

Step-by-step explanation:

9.V=l*w*h

  V=10*8*6

  V=480  

10.V=pi*1^2*8

    V=8pi

    V=25.1

11.V=1/3pi*6^2*10

   V=1/3pi*36*10

   V=1/3pi *360

  V=120pi

   V=377

12.V=l*w*h/3

   V=10*8*6/3

   V=480/3

   V=160

13.V=4/3pi*3.5^3

   V=4/3pi *42.875

   V=171.5/3pi

   V=179.6

14.V=2/3pi*6^3

   V=2/3pi*216

  V=432/3pi

  V=144pi

  V=452.4

Answer:

W = 15.5 in.

A = 240.25 in.^2

Step-by-step explanation:

L = 31 in.

W = 1/2 W = 15.5 in.

A = LW/2

A = 31 in. * 15.5 in. / 2

A = 240.25 in.^2

(2/1 )(3/2)(4/3)...(n-1/n-2)(n/n-1)(n+1/n) = n + 1

n + 1 = n + 1

1 = 1 ( Fact )

Thus it is not importent what the value of n is at all because the equation is always have the equal number ( which is 1 ) in both sides .

Answer:

A is correct.  f(n) = -3n + 24

Step-by-step explanation:

We can see in the first two steps that two meals have been served, and six cups of pet food consumed.  In other words, six cups are consumed in two meals, therefore three cups are consumed in each meal.

If we look at the remaining numbers on the chart, we can see that this carries through.  This tells us that the correct answer must be either a or b, as "-3n" represents the consumption rate.  If it were (1/3)n, then only a third of a cup would be consumed per meal.

Finally, we can figure out which of those two equations is correct simply by plugging a value pair into them.  Starting with a:

f(1) = -3(1) + 24

= 24 - 3

= 21

correct.

To be certain, let's check with answer c:

f(1) = -3(1) + 64

= 64 - 3

= 61

incorrect.

So we can clearly say that the correct answer is "a".  You can plug the other values into it to test that too:

f(3) = -3(3) + 24

= 24 - 9

= 15

correct

So we definitely have the right answer.

Cos 0° = Sin 90°

Cos 30° = Sin 60°

Cos 45° = sin 45°

Cos 60° = sin 30°

Cos 90° = sin 0°
