Sarah draws a rectangle with an area of 4,875 square units and a length of 65 units. What is the width of the rectangle? 70 units 75 units 85 units 95 units

Answers

Answer 1

To calculate area of a rectangle you multiply the length and width together so to find the width you divide the area by the length: 4875÷65=75 so the width is 75 units.

There are 20,000 owls in the wild. Every year the population decreases by 8%. How many owls will there be after 8 years?

Answers

After 8 years, there will be approximately 10,260 owls remaining in the wild. This calculation is based on an initial population of 20,000 owls decreasing by 8% annually, yielding a final population using the formula for exponential decay.

To find out how many owls will remain after 8 years, we can use the formula for exponential decay:

[tex]\[ \text{Final population} = \text{Initial population} \times (1 - \text{Rate of decrease})^{\text{Number of years}} \][/tex]

Given:

Initial population (P) = 20,000 owls

Rate of decrease (r) = 8% = 0.08

Number of years (t) = 8

Plugging in the values:

[tex]\[ \text{Final population} = 20,000 \times (1 - 0.08)^8 \][/tex]

[tex]\[ \text{Final population} = 20,000 \times (0.92)^8 \][/tex]

[tex]\[ \text{Final population} \approx 20,000 \times 0.513 \][/tex]

[tex]\[ \text{Final population} \approx 10,260 \][/tex]

So, after 8 years, there will be approximately 10,260 owls remaining in the wild.

He measure of one angle of an octagon is twice that of the other seven angles. what is the measure of each angle? answer: ,

Answers

Final answer:

The measure of one angle in an octagon is 135.625 degrees.

Explanation:

Let's denote the measure of one angle as x.

Since there are eight angles in an octagon,

the sum of all the angles in the octagon is 180(x) + 7(2x) = 180x + 14x = 194x.

We know that the sum of the angles in any polygon is equal to (n-2) times 180 degrees, where n is the number of sides of the polygon.

Therefore, 194x = (8-2) × 180. Solving this equation,

we find that x = 135.625. So, the measure of each angle is 135.625 degrees.

Adventure Play sells an mp3 player for $18.00 and charges $3.25 per song. King Music sells a player for $23.00 and charges $2.00 per song. For how many songs will the cost be the same?

Answers

Answer: 4

Explanation:

Translate the english language to mathematical (algebraic) language.

This implies to define the variables and translates the statements into equations.

1) Adventure Play sells an mp3 player for $18.00 and charges $3.25 per song.

Cost = price of the mp3 player + price each song * number of songs

Variables:

number of songs: n
price each son: $3.25
price of the mp3 player: $ 18.00
Cost: c(n), this means that the cost is a function of n.

c(n) = 18 + 3.25n

2) King Music sells a player for $23.00 and charges $2.00 per song. For how many songs will the cost be the same?

Using the same procedure used for Adventure Play case:

c(n) = 23 + 2n

3) Equal cost =>

18 + 3.25n = 23 + 2n

=> 3.25n - 2n = 23 - 18
=> 1.25n = 5
=> n = 5 / 1.25
=> n = 4

Answer: the cost will be the same for 4 songs.

What is the slope of the line 3x + 4y = -11?

answers:
3\4
-3\4

4

Answers

you need to make it in the form of y=mx+b, and m will be the slope
so...
3x-4y=7
subtract 3x from both sides
-4y=-3x+7
then divide both sides by -4
y=(3/4)x-7/4

so the slope is 3/4

Final answer:

To find the slope of the line given by 3x + 4y = -11, the equation is rearranged into the slope-intercept form, yielding a slope (m) of -3/4.

Explanation:

The question asks: What is the slope of the line 3x + 4y = -11?

To find the slope of the line, we first need to rearrange the equation into the slope-intercept form, which is y = mx + b, where m is the slope, and b is the y-intercept. Starting with the given equation

3x + 4y = -11

We isolate y on one side by first moving 3x to the right side of the equation, and then dividing everything by 4:

4y = -3x - 11y = (-3/4)x - 11/4

Now, in the form of y = mx + b, it's clear that the slope (m) of the line is -3/4.

What is general form of equation of a circle with center at (a,b) and radius of length m?

Answers

All points on a circle has the same distance (radius) to the center. Specifically, the distance from point (x,y)to center (a,b) is \sqrt((x-a)^2+(y-b^2)), which is equal to radius m. So \sqrt((x-a)^2+(y-b^2))=m. Square both sides, (x-a)^2+(y-b)^2=m^2.

The general form of the equation of a circle with centre at [tex]$(a, b)$[/tex] and radius [tex]$m$[/tex] is: [tex]\[ x^2 + y^2 - 2ax - 2by + (a^2 + b^2 - m^2) = 0 \][/tex].

The general form of the equation of a circle is [tex]$ (x - h)^2 + (y - k)^2 = r^2 $[/tex], where [tex]$(h, k)$[/tex] represents the centre of the circle and [tex]$r$[/tex] represents the radius.

If we expand and rearrange this equation, we get [tex]$ x^2 + y^2 - 2hx - 2ky + (h^2 + k^2 - r^2) = 0 $[/tex].

Comparing this with the given options, we see that [tex]$ h = a $, $ k = b $, and $ r = m $[/tex].

Substituting these values into the general form, we get [tex]$ x^2 + y^2 - 2ax - 2by + (a^2 + b^2 - m^2) = 0 $[/tex], which matches the correct option.

Complete Correct Question:

What is the general form of the equation of a circle with center at (a, b) and radius of length m?

a. x2 + y2 - 2ax - 2by + (a2 + b2 - m2) = 0.

b. x2 + y2 + 2ax + 2by + (a2 + b2 - m2) = 0.

c. x2 + y2 - 2ax - 2by + (a2 + b2 + m2) = 0.

d. x2 + y2 + 2ax + 2by + a2 + b2 = -m2.

The perimeter of a rectangular outdoor patio is 60 ft. the length is 4 ft greater than the width. what are the dimensions of the patio? l w

Answers

The length of rectangular outdoor patio is 17 feet and the width is 13 feet.

Given that, the perimeter of a rectangular outdoor patio is 60 ft.

What is the perimeter of a rectangle?

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Let the width of the rectangular outdoor patio be x.

Then, the length is 4 ft greater than the width = x+4

Now, perimeter = 2(x+x+4)

⇒ 2(2x+4) = 60

⇒ 4x+8=60

⇒ 4x=52

⇒ x=13

Length = x+4 = 17

Therefore, the length of rectangular outdoor patio is 17 feet and the width is 13 feet.

Sn = [tex] \frac{a1(r^n - 1)}{r -1} [/tex]
a₁ = first term of sequence = -8
r = common ration = -2
n = term of sum we need to find = 7

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Let x be the total number of dogs and cats are in the animal shelter.

So, 32% of x=16
