A pool measuring 8 meters by 24 meters is surrounded by a path of uniform
width, as shown in the figure. If the area of the pool and the path combined is
960 square meters, what is the width of the path?
Answer:
8 meters
Step-by-step explanation:
8 × 24 = 192, 960 - 192 = 728.
The width of the path will be 8, and the length of the path will be 91, but since the question is just talking about the path's width, then the answer is 8 meters.

Determine the missing term from the perfect square trinomial. Show ALL work. x2 − ______+ 36
Answer:
12x
Step-by-step explanation:
Given the perfect square trinomial: [tex]x^2-()+36[/tex]
Written in the form [tex](x+k)^2[/tex]
[tex]x^2-()+36=x^2-()+6^2=(x-6)^2[/tex]
[tex](x-6)^2=(x-6)(x-6)\\=x^2-6x-6x+36\\=x^2-12x+36[/tex]
The missing term therefore is 12x.

Jessica has been tracking the population of a town. The population was 8,230 last year and has been increasing by 1.25 times each year. How can Jessica develop a function to model this?
Answer:
Population at start : 8,230.
The rate of growth: r = 1.25
x - number of the years;
Answer:
B ) f ( x ) = 8,230 * ( 1.25 ) ^x where 1.25 is the rate of growth.
Step-by-step explanation:
Jessica develops a function to model this 8230(1.25)ˣ, where 1.25 is the rate of growth.
What is exponential population growth?In an ideal condition where there is an unlimited supply of food and resources, the population growth will follow an exponential order.
Jessica has been tracking the population of a town.
The population was 8,230 last year and has been increasing by 1.25 times each year.
The population growth function is;
[tex]\rm f(x)=P_0 x^t[/tex]
Substitute all the values in the formula;
[tex]\rm f(x)=P_0 x^t\\\\f(x) = 8230 (1.25)^x[/tex]

Together Emily and Charlotte have a total of 60 strawberries Emily eats four times the amount that Charlotte eats how many strawberries does Charlotte eat?
Answer:
12
Step-by-step explanation:
If you were asking how many strawberries it would take to finish all 60, this is the answer, otherwise please rephrase the question.
If Charlotte ate 12 strawberries, you would have to do 12 x 4 which would be four times the amount of strawberries Charlotte ate, 12 x 4 = 48, Emily ate 48 strawberries, 48 + 12 = 60.
Charlotte eats 12 strawberries.
Let the amount of strawberries eaten by Charlotte be represented by x.
Since Emily eats four times the amount that Charlotte eats, then Emily will eat:
= (4 × x) = 4x.
Since Emily and Charlotte have a total of 60 strawberries, then this will be:
4x + x = 60
5x = 60
x = 60/5
x = 12
Therefore, Charlotte eats 12 strawberries.

What is the vertex of the quadratic function with a positive a value?
Answer:
If the coefficient of the squared term is positive, the parabola opens up. The vertex of this parabola is called the minimum point. If the coefficient of the squared term is negative, the parabola opens down. The vertex of this parabola is called the maximum point.
The graph opens upward, if the vertex of the quadratic function with a positive a value.
Given that, the quadratic function with a positive a value.
What is the vertex of the quadratic function?The vertex of the graph of a quadratic function is the highest or lowest possible output for that function. If you're looking at a graph, the vertex would be the highest or lowest point on the parabola. The easiest way to find the vertex is to use the vertex formula.
If a is positive, the graph opens upward, and if a is negative, then it opens downward. The line of symmetry is the vertical line x = h, and the vertex is the point (h, k). Any quadratic function can be rewritten in standard form by completing the square.
Therefore, the graph opens upward, if the vertex of the quadratic function with a positive a value.

Helppp!
Answer:
[tex]5x+3x \leq 45[/tex] represents all possible combinations of x tulips and y carnations
Step-by-step explanation:
We are supposed to find inequality represents all possible combinations of x tulips and y carnations
Cost of 1 tulip = $5
Cost of x tulips = 5x
Cost of 1 carnation =$3
Cost of y carnations = 3y
We are given that she does not want to spend more than $45.
So, She can spend less than or equal to 45
So, required inequality :[tex]5x+3x \leq 45[/tex]
So, Option B is true
[tex]5x+3x \leq 45[/tex] represents all possible combinations of x tulips and y carnations

Need Help ASAP it's due today. Angelica uses the point (4,3) to represent the location of her house and uses the point (10,8) to represent the location of a gas station. Each unit on the graph represents 1 mi. How far is the gas station from Angelica's house? SHOW YOUR WORK. ( The teacher said to Plot a third point, connect the third point to make a right triangle, find the lengths of the legs of the triangle and then use the pythagorean theorem to find the distance between the gas station and Angelica's house). Only answer if you truly know how to solve this please. Will Mark Brainliest
Answer:
About 7.8 miles.
Step-by-step explanation:
We can use the distance formula to find the distance from the gas station to the house.
However, your teacher said to use the Pythagorean Theorem to find the distance.
Going by your teacher's preferred method:(4,3), (10,8), and (10,3) would make a right triangle.
[See Picture]
Angelica's house is at point (4,3). It is 6 units from our new third point.
The gas station is at point (10,8). It is 5 units form out new third point.
The legs are 5 and 6 units. The distance from the house to the gas station would be our hypotenuse.
Use the Pythagorean Theorem to find the length of the hypotenuse.
[tex]a^2 + b^2 = c^2\\\\\text {Replace a and b with the appropriate values: }\\6^2 + 5^2 = c^2\\\text {Solve: }\\6^2 + 5^2 = c^2\\6^2 = 36\\5^2 = 25\\\rightarrow 36 + 25 =c^2\\36 + 25 = 61\\\rightarrow 61=c^2\\\sqrt{61}=\sqrt{c} \\\boxed {7.81024967591=c}[/tex]
7.81024967591 ≈ 7.8
The hypotenuse is about 7.8.
Therefore, the distance between the gas station and Angelica's house should be about 7.8 miles.

Answer:
AG = 7,8
Step-by-step explanation:
Plot the third point at (10,3) and let's call it point B.
Now construct the right sided triangle A B G
With A = (4,3) , B = (10,3) and G = (10,8).
AB is horizontal so subtract the x coordinates of point A and point B. So AB has length 10 - 4 = 6
BG is vertical so subtract the y coordinates of point B and point G. So BG has length 8 - 3 = 5
Now use pythagorean theorem to calculate AG
In any right sided triangle you can use a² + b² = c²
In our case AB² + BG² = AG²
Substitute AB = 6 and BG = 5
6² + 5² = AG²
AG² = 6*6 + 5*5
AG² = 36 + 25
AG = + - SQRT(61)
{Only the + variant of the SQRT has a meaning here.}
AG = 7,81 rounded on one decimal AG = 7,8
The diameter of a circle is 6
inches. What is its
approximate
area?
Answer:
A =28.26 inches^2
Step-by-step explanation:
The diameter is 6 so the radius is d/2 = 3
The area is given by
A = pi r^2
A = pi (3)^2
A = 9pi
Using 3.14 for pi
A = 9 * 3.14
A =28.26 inches^2
Answer:
~28.2743
Step-by-step explanation:
- The formula for a circle's area is: Area= pi * radius^2
1.) We know the diameter is 6, and the radius is ALWAYS half of the diameter so the radius=3.
2.) Now we square the radius and multiply it by pi, which ends up as ~28.2743 as the area.
