Answer:
She will be able to pay off her loan completely in approximately 50 months
Step-by-step explanation:
The amount Esme earns as net salary = $2,400
The amount she already has in a savings account = $100
The amount she would be able to add to her savings account every month = $100
The cost of the car Esme plans to purchase on the no interest loan, A = $20,000
The amount she will make as payment on the loan every month, P = $300 per month
Let 'x' represent the number of month Esme will be able to pay off her loan completely, we have
The number of month Esme will have enough money to pay off her loan completely is given by the following equation;
20,000 = 100 + 300 × x + 100 × x = 100 + 400·x
∴ x = (20,000 - 100)/400 = 49.75
Therefore, the number of months she will be able to pay off her loan completely = 49.75 months ≈ 50 months.
20 Alex and Chris share sweets in the ratio Alex : Chris = 7:3.
Alex receives 20 more sweets than Chris.
Work out the number of sweets Chris receives.
Answer:
Alex:Chris 35:15
Step-by-step explanation:
7-3 (ratios)= 4
20 sweets= 4:1
20÷4= 5
5×7= 35 (how many sweets Alex got)
5×3= 15 (how many sweets Chris got)
Alex got 20 more sweets than Chris

Step-by-step explanation:
A picture that measures 7 inches
by 7 inches is being framed.
The area of the picture with
frame is 81 square inches.
What is the width of the frame?
Answer:
The width of the frame is 2 inches
Step-by-step explanation:
The given dimensions of the picture = 7 inches by 7 inches
The area of the picture, A₁ = 7 in. × 7 in. = 49 in.²
The area of the given picture and the frame, A₂ = 81 square inches
Let 'w' represent the width of the frame and whereby the picture is a square, we have;
The area of the picture with the frame, A₂ = 81 in.² = (7 + w) × (7 + w)
A₂ = 81 = (7 + w) × (7 + w) = 49 + 14·w + w²
49 + 14·w + w² - 81 = 0
w² + 14·w - 32 = 0
(x + 16)·(x - 2) = 0
∴ x = -16 or x = 2
Given that 'x' is a natural number, we have;
The width of the frame, x = 2 inches.

1. The points ( − 4, − 4), ( − 4, 4), (4, 4), and (4, − 4) form a square on a coordinate plane. How long is a side length of the square
Answer:
Length of one side is 8 units
Step-by-step explanation:
Given
The centre of this square is positioned at the origin as visible form the four co-ordinates
All the four co-ordinates are such that they are 4 units along the x-axis and 4 units along the y-axis.
Let us take the following two co-ordinates - (4,4),(4,−4). The X value for these two co-ordinate points is 4 and the Y values are such that one point has y = 4 and the other has y = -4 i.e 8 units in between.
Thus, length of one side is 8 units.
What is linear equation???
Answer:
an equation between two variables that gives a straight line when plotted on a graph. In mathematics, a linear equation is an equation that may be put in the form {\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}} are the coefficients, which are often real numbers.

If one side of a regular pentagon is represented by 3x + 1 , what is the perimeter of the pentagon?
Answer:
5(3x+1) or 15x+5
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +1)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 5

Determine the value of x in the given figure help
Answer:
x = 25
Step-by-step explanation:
The angles in a triangle must add up to 180 degrees, so:
180 - (53 + 27) = 100
100 ÷ 4 = 25

Step-by-step explanation:
Calinda is painting the design on her bedroom wall. The large circle has a diameter of 32 inches. To the nearest square inch, how much paint swill she need for the shared reign on
Answer:
804 inches
Step-by-step explanation:
Amount of paint she would need is equal to the area of the circle
Area of a circle = πr²
π = 3.14
r = 32/2 = 16
The diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x 16² = 804 in
please help im very very desperate
Answer:
Exponential
Step-by-step explanation:
If it were quadratic, y-axis would fall and rise in points, so its not quadratic.
If it were linear, it would have a pattern with a rise/over formula, and it doesn't go in a pattern, so the only answer left is: Exponential.
Answer:
Exponential

Rotate an isosceles right triangle around a line that contains the triangle's hypotenuse
Answer:
See attachment 2 for the rotation
Step-by-step explanation:
The question has a missing figure
See attachment 1 for the missing figure of the isosceles right-triangle
Required
Rotate around the hypotenuse
From the attachment, the hypotenuse is along the blue vertical line along the y-axis.
So, when the isosceles triangle is rotated around the hypotenuse, the result of the rotation we get a composite figure that has two congruent solids.
Which is a cone of radius and height equal to half of the hypotenuse
See attachment 2 for the rotation

en las matematicas para que concepto se usan las letras?
Answer:
En matemáticas, las letras son utilizadas en las ecuaciones, para representar a través de ellas valores no conocidos que deben ser dilucidados por quien realiza la ecuación. Las letras más utilizadas con este propósito son las letras X e Y.
Así, por ejemplo, se da una suma con un valor numérico y un valor faltante denominado X, con un resultado también numérico, con lo cual el valor de X surgirá del resultado de la ecuación planteada. Por ejemplo:
8 + X = 10
X = 10 - 8
X = 2
8 + 2 = 10

A random variable X follows a Binomial distribution; i.E. X ~ B(12, p) with a variance of 1.92. Compute the possible values of p
==================================================
Explanation:
Any binomial distribution has two unique components to it: The number of trials n, and the probability of success p.
We're given n = 12, and we need to find p.
The variance of a binomial probability distribution is given by the formula n*p*(1-p). Plug in n = 12 and set this equal to 1.92
So the equation to solve is 12p*(1-p) = 1.92
Solve for p using a graphing calculator or you could apply the quadratic formula. Either way, you should get the two results of p = 0.2 and p = 0.8
Note that if p = 0.2, then 1-p = 1-0.2 = 0.8, and things flip around when p = 0.8.
A window washer cleaned 38 windows in 2 hours. At this rate, how many windows did he clean in 7 hours?
plz help
Answer:
133 windows in 7 hours
Step-by-step explanation:
38 divided by 2 and you get 19
19 x 7 = 133
Answer:
133 windows
Step-by-step explanation:
First, you would want to find how many windows he can clean in 1 hour.
You know that 38 windows = 2 hours.
To do this, divide both sides by 2 (to get 1 hour). You will get 19 windows = 1 hour.
Now to find 7 hours, multiply both sides of 19 windows = 1 hour by 7 (to get 7 hours). You will get 133 windows cleaned in 7 hours.
