what would the answer be?

Answer: 111.11 seconds

Step-by-step explanation:

Given: The period of a pendulum is the time the pendulum takes to swing back and forth

The function relates the length [tex]L= 0.81t[/tex] in feet of a pendulum to the time t in seconds that it takes to swing back and forth.

If L= 90 feet then put this in the above function, we get

[tex]90=0.81t\\\\\Rightarrow\ t=\dfrac{90}{0.81}\\\\\Rightarrow\ t=111.1111111\approx111.11\text{ seconds}[/tex]

Hence,  the period = 111.11 seconds

Answer:

2

Step-by-step explanation:

We can find the slope using the formula

m = ( y2-y1)/(x2-x1)

   = ( 5-1)/( -1 - -3)

   = ( 5-1)/( -1+3)

   = 4/2

   = 2

Answer: 2

Step-by-step explanation:

( y2-y1)/(x2-x1)

  = ( 5-1)/( -1 - -3) =  ( 5-1)/( -1+3) = 4/2  = 2

Answer:

  $4(12)

  $48

Step-by-step explanation:

The problem is telling you fees are $4 per month. It is asking the amount of fees for a year.

You find the yearly amount by multiplying the monthly amount by the number of months in a year:

  (fees for year) = (fee for month)×(number of months in a year)

All it is asking for is the product expression:

  $4 × 12

Answer:

[tex]38 x = 54[/tex]

Step-by-step explanation:

Required

Determine the number of 38 in 54

We start by representing the number of 38 in 54 with x

To determine the number of 38 in 54, we have to represented it as thus:

[tex]38 * x = 54[/tex]

Simplify the expression as follows:

[tex]38 x = 54[/tex]

The expression can be left like that or simplified further by dividing through by 2:

[tex]19x = 27[/tex]

Hence, the solution to the question is:

[tex]19x = 27[/tex] or [tex]38 x = 54[/tex]

Answer:

Y: Total cost

M:50

X: Hours renting

Equation: y=50x+250

Answer:

solve for x in the second equation is correct

Step-by-step explanation:

Here is the complete question

Which first step for solving the given system using substitution results in an equation without fractions?

(2x+6y=7

(6x + 18y = 24.... 2

Solve for x in the first equation,

Solve for y in the first equation,

Solve for x in the second equation

The best equation to she will be equation 2 since all the coefficients are end numbers

Let us make x t subject f the formula from equation 2;

From 2: 6x+18y = 24

Subtract 18y from both sides

6x+18y-18y = 24-18y

6x = 24-18y

Divide through by 6

6x/6 = 24/6 - 18y/6

x = 4-3y.

You can see that the resulting expression of x is not a fraction. Hence solve for x in the second equation is correct

Answer:

$79.7468

Step-by-step explanation:

6.4% of 74.95 is 4.7968, since 6.4 * 74.95 is 479.68, and if you divide that by 100, you will get 4.7968. 4.7968 + 74.95 = $79.7468

Here we want to find the total cost of a coat given that we know its cost and the sales tax.

By working with percentages, we will find that the total cost will be $79.75

So the cost of the coat is $74.95, and then we must pay an extra 6.4%

Then we must pay a total of the 100% + 6.4% = 106.4%

And the 100% is equivalent to $74.95

Then the 106.4% is equivalent to:

(106.4%/100%)$74.95 = $79.75

So the total cost of the coat is $79.75

Given :

Nami is wrapping packages with green and pink ribbon.

She has 11.85 meters of green ribbon and 13.4 of pink ribbon.

To Find :

How many more meters of pink ribbon are their than green.

Solution :

Length of green ribbon, g = 11.85 m .

Length of pink ribbon, p = 13.4 m .

Amount of pink more than green is :

A = 13.40 - 11.85

A = 1.55  m

Therefore, pink ribbon is 1.55 meter more than green one.

Hence, this is the required solution.

Answer:

The exact price of the couch is $493.75

Step-by-step explanation:

Here, we want to find the price of the couch given the mark up percentage

Mathematically, that would be;

395 + (25% of 395)

= 395 + 25/100 * 395

= 395 + 395/4

= 395 + 98.75

= $493.75

Answer:

[tex]\frac{73}{36}[/tex]

Step-by-step explanation:

[tex]\frac{3}{4}[/tex] - [tex]\frac{2}{9}[/tex] + [tex]\frac{3}{2}[/tex]

1. Convert all the fractions to a common denominator.

For this problem, the common denominator will be 36

[tex]\frac{3}{4}[/tex] * 9 = [tex]\frac{27}{36}[/tex]

[tex]\frac{2}{9}[/tex] * 4 = [tex]\frac{8}{36}[/tex]

[tex]\frac{3}{2}[/tex] * 18 = [tex]\frac{54}{36}[/tex]

2. Substitute the values back into the equation, and solve

[tex]\frac{3}{4}[/tex] - [tex]\frac{2}{9}[/tex] + [tex]\frac{3}{2}[/tex]

= [tex]\frac{27}{36}[/tex] - [tex]\frac{8}{36}[/tex] + [tex]\frac{54}{36}[/tex]

= [tex]\frac{19}{36}[/tex] + [tex]\frac{54}{36}[/tex]

Answer:

y = -3x - 2

Step-by-step explanation:

Equation of a line passing through [tex](x_1,y_1)[/tex] and slope m is,

[tex]y-y_1=m(x-x_1)[/tex]

Slope of a line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of the line passing through (0, -2) and (1, -5) will be,

Slope = [tex]\frac{-2+5}{0-1}[/tex]

m = - 3

Therefore, equation of the line passing through (0, -2) and slope = -3 will be,

y + 2 = -3(x - 0)

y + 2 = -3x

y = -3x - 2

Step-by-step explanation: Remember, I=prt. So multiply 12,000x0.04x4. The final answer is $1,920.

Answer:

$1920

Step-by-step explanation:

He starts with 12,000 dollars. If he makes 4 percent of that, he is making 480 dollars every year. So you know how much he is making every year, you need to know what he is making in 4 years. 480 * 4 = 1920

Answer:

18.8 ft

20.8 ft

Step-by-step explanation:

Given that :

Dimension of rectangular patio:

13 feets * 15 feets

To double the area of The patio :

2 * initial. Area

Initial Area = area of rectangle = Length * width

Initial area = 13 * 15 = 195ft²

New area of patio = 2 * 195 ft² = 390 ft²

To obtain the new area, the length and width of patio increased in equal amount:

Let the Increment = x

Hence,

(length + x) * (width + x) = 390

(13 + x) * (15 + x) = 390

195 + 13x + 15x + x² = 390

195 + 13x + 15x + x² - 390 = 0

x² + 28x - 195 = 0

Using the quadratic equation solver to save computation time :

The roots are :

X = - 33.773 or 5.773

Dimension can't be negative, hence,

x = 5.773

New dimension :

(length + x) = 13 + 5.773 = 18.8 ft

(width + x) = 15 + 5.773 = 20.8 ft

Answer:

[tex]Width = a^2 + 2a - 3[/tex]

Step-by-step explanation:

Given

[tex]Area = 5a^4 + 10a^3 - 15a^2[/tex]

[tex]Length = 5a^2[/tex]

Required

Determine the Width

The area of a rectangle is calculated using:

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

Make Width the subject

[tex]Width = \frac{Area}{Length}[/tex]

Substitute values for Area and Length

[tex]Width = \frac{5a^4 + 10a^3 - 15a^2}{5a^2}[/tex]

Factorize the numerator

[tex]Width = \frac{5a^2(a^2 + 2a - 3)}{5a^2}[/tex]

[tex]Width = a^2 + 2a - 3[/tex]

Hence, the polynomial for the width of the rectangle is:

[tex]Width = a^2 + 2a - 3[/tex]
