21/32 ÷ 3/5​

Answer:

Step-by-step explanation:

Let x represent the number of tickets sold, and y represent the total amount of money raised. Since each ticket is $2.50, the total amount of money raised is equal to $2.50 times the number of tickets. The equation would be y = 2.50x.

Answer:

y=2.5x

The total amount of money raised(y) = how many tickets are sold(x) x the price per ticket(2.5)

Hypothetically, if 24 tickets were sold, we could substitute 24 into x...

y=2.5(24)

y=60

Let x represent the number of tickets sold, and y represent the total amount of money raised. Since each ticket is $2.50, the total amount of money raised is equal to $2.50 times the number of tickets. The equation would be y = 2.50x.

The x variable represents the number of tickets sold.

The y variable represents the total amount of money raised from ticket sales.

The equation for the scenario is y = 2.50x.

Answer:

The house is increasing in value by 2% each year.

Correct the increase is 1.02 per year the value of b>0 and the percentage of increase each year is:

[tex] \frac{1.02-1}{1} *100 = 2\%[/tex]

Step-by-step explanation:

For this case if we have this expression

[tex] 210000(1.02)^x[/tex]

We have the same functional forma like the exponential model given by:

[tex] y = a b^x[/tex]

Where a = 210000 represent the constant or initial value and b = 1.02 represent the base.

So let's analyze the possible options:

The house has a starting value of 1.02.

False the starting value for this case is 210000 since if x=0 then we see that the value is 210000

The house is decreasing in value by 2% each year.

False the increase is 1.02 each year so then in % we have

[tex] \frac{1.02-1}{1} *100 = 2\%[/tex]

We  have an increase of 2% each year

The house is increasing in value by 2% each year.

Correct the increase is 1.02 per year the value of b>0 and the percentage of increase each year is:

[tex] \frac{1.02-1}{1} *100 = 2\%[/tex]

The value of the house is changing by 0.02% each year.

False the increase is 2% per year

Answer:

5/3

Step-by-step explanation:

30/18

you can easily simplify a large improper fraction by finding a common number.

in this case the number is 6.

6x5=30 & 6x3=18

therefore, if you divide each number by 6 you get 5/3

decimal: 1.66667 or 1.67 or 1.7

improper fraction: 5/3

proper fraction 1 2/3

Final answer:

30 divided by 18 as an improper fraction is ⅓, or 5/3, obtained by converting the division result into a mixed number and then back into an improper fraction.

Explanation:

To convert 30 divided by 18 into an improper fraction, you first divide 30 by 18 to get the decimal form, which is approximately 1.666. To express this as an improper fraction, we recognize that 1.666 is 1 and 2/3 in mixed number form.

Since 2/3 is already a fraction, we can convert the mixed number back into an improper fraction by multiplying the whole number 1 by the denominator 3 and then adding the numerator 2. This gives us 3 + 2 = 5, so the improper fraction is 5/3.

Answer:

3/20

Step-by-step explanation:

Prob. (For green (Bag A)) = 3/12

Prob. (For Black (Bag B)) = 9/15

3/12 x 9/15 = 3/20

The probability of selecting one green marble from bag A and one black marble from bag B is 0.15

There are 3 green marbles in bag A out of a total of 12 marbles (i.e. 3 green and 9 red).

So, the probability of selecting a green marble from bag A is:

[tex]Pr = \frac 3{12}[/tex]

There are 9 black marbles in bag B out of a total of 15 marbles (i.e. 9 black and 6 orange).

So, the probability of selecting a black marble from bag B is:

[tex]Pr = \frac 9{15}[/tex]

The required probability is then calculated as:

[tex]P = \frac 3{12} * \frac 9{15}[/tex]

Multiply

[tex]P = 0.15[/tex]

Hence, the probability of selecting one green marble from bag A and one black marble from bag B is 0.15

What are the factors of the polynomial?

(2x+3)(x+1)

(2x-3)(x-1)

(3x+2)(x+1)

(3x-2)(x-1)

Option A

The factors are:

[tex]2x^2+5x+3 = (2x+3)(x+1)[/tex]

Given that, the quadratic equation is:

[tex]2x^2 + 5x + 3[/tex]

We have to find the factors of polynomial

[tex]2x^2+5x+3[/tex]

Split 5x as 2x and 3x

[tex]2x^2+5x+3 = 2x^2 +2x + 3x + 3[/tex]

[tex]\mathrm{Break\:the\:expression\:into\:groups}[/tex]

[tex]2x^2+5x+3 = 2x(x+1) + 3(x+1)[/tex]

[tex]\mathrm{Factor\:out\:common\:term\:}x+1[/tex]

Thus we get,

[tex]2x^2+5x+3 = (2x+3)(x+1)[/tex]

Thus the factors are found for given polynomial

Final answer:

The correct factors of the polynomial +5x+3 are (2x+3)(x+1), as they multiply to give the original polynomial. None of the other provided options yield the correct polynomial upon multiplication.

Explanation:

The question asks to identify the factors of the polynomial +5x+3. Factors are expressions that, when evaluated, produce the value of the polynomial. Let's examine the provided options to find which pair of binomials gives us the correct polynomial upon multiplication:

(2x+3)(x+1) = 2x² + 2x + 3x + 3 = 2x² + 5x + 3, which matches the original polynomial.

(2x-3)(x-1) = 2x² - 2x - 3x + 3 = 2x² - 5x + 3, which does not match the original polynomial.

(3x+2)(x+1) = 3x² + 3x + 2x + 2 = 3x² + 5x + 2, which does not match the original polynomial.

(3x-2)(x-1) = 3x² - 3x - 2x + 2 = 3x² - 5x + 2, which does not match the original polynomial.

Therefore, the correct factors of the polynomial +5x+3 are (2x+3)(x+1).

Answer: The length is 62 inches and the width is 13 inches

Step-by-step explanation: The perimeter of the rectangular portrait has been given as 150 inches. We also know that the perimeter of a rectangle is given as

Perimeter= 2(L + W)

However we don't have the measurements for the length and width. What we do have are descriptions of both. The length is given as W, while the length is ten more than four times the width. That is, the length equals

10 + 4W

Therefore we have the length and the width as

L = 4W + 10 and

W = W

If the perimeter is 150, and

Perimeter = 2(L + W) then,

150 = 2(4W + 10 + W)

150 = 2(5W + 10)

150 = 10W + 20

Subtract 20 from both sides of the equation

130 = 10W

Divide both sides of the equation by 10

13 = W

With that in mind we can now calculate the length as

L = 4W + 10

Substitute for the value of W

L = 4(13) + 10

L = 52 + 10

L = 62

Therefore, the length is 62 inches and the width is 13 inches

Answer:

Length = 62 inches, Width = 13 inches

Step-by-step explanation:

Let L represent the length of the frame, W, the width and P, the perimeter

Perimeter of a rectangle, P = 2 (L + W) .....eq 1

Also, P = 150 inches

and

L = 10 + 4W .....eq 2

Slotting in the respective values of P and L in eq 1

150 = 2 {(10 + 4W) + W}

Expanding the bracket

150 + 2 (10 + 5W)

150 = 20 + 10W

Subtracting 20 from both sides of the equation

150 - 20 = 20 - 20 + 10W

130 = 10W

Dividing both sides by the coefficient of W which is 10

13 = W

Therefore, W = 13 inches

Slotting in the value of W in eq 2

L = 10 + 4 (13)

L = 10 + 52

L = 62 inches

Lets ensure that the values of L and W are correct

P = 2 (L + W)

150 = 2 (13 + 62)

150 = 2(75)

150 = 150

Hence, L = 62 inches, W = 13 inches

The trigonometric functions are very important in math and physics. Sound, light and electricity all involve oscillations and are modeled by sine and cosine functions. So, we can provide a trig ratio for the sine and cosine function by taking a right triangle as shown in the figure below. So the relationships are as follows:

[tex]sinA=\frac{Opposite \ side}{Hypotenuse} \\ \\ cosA=\frac{Adjacent \ side}{Hypotenuse} \\ \\ \\ For \ the \ figure: \\ \\ a:Opposite \ side \\ \\ b:Adjacent \ side \\ \\ c:Hypotenuse[/tex]

So we can write:

Answer:

30

Step-by-step explanation:

It states that it rained twice as much in 5 days all you do is multiply the 2 times 3 which is 6 so then u multiply 6 times 5 which is 30.

The river rose a total of 93 inches over five days.

The question asks how much a river rises in five days given a certain pattern of increase. To find the solution, we use a geometric sequence because the river rises by a constant multiple each day. On the first day, the river rises three inches. Since on each subsequent day the river rises by twice the amount it did the previous day, the sequence of increases over five days is: 3 inches, 6 inches, 12 inches, 24 inches, and 48 inches.

The total rise of the river is the sum of these increases:

3 + 6 + 12 + 24 + 48 = 93 inches.

Therefore, the river rose a total of 93 inches over the span of five days.

By substituting x = -2 in each expression, we find that x-2 equals -4, x-1 equals -3, x₀ equals 1, x₁ equals -2, and x₂ equals 4.

To solve this, we need to substitute x = -2 into each expression. Here are the results:
