There is $2.4 less is the sale price of the black coat than the sale price of the blue coat.
What is discount?Discount is a kind of reduction or deduction in the cost price of a product.
Given
Maria is trying to decide which one of two winter coats she should buy.
The blue coat usually costs $48 but is on sale for 25% off.
The black coat usually costs $56 but is on sale for 40% off.
The cost of the blue coat after 25% discount;
[tex]= 48\times \dfrac{25}{100}\\\\= 48 \times \dfrac{1}{4}\\\\= 12[/tex]
The cost of the blue coat after discount = $48 - $12 = $36
The cost of the black coat after 40% discount;
[tex]= 56 \times \dfrac{40}{100}\\\\= 56 \times 0.40\\\\=22.4[/tex]
The cost of the black coat after discount = $56 - $22.4 = $33.6
The price of the coat less is the sale price of the black coat than the sale price of the blue coat is;
= $36 - $33.6
= $2.4
Hence, there is $2.4 less is the sale price of the black coat than the sale price of the blue coat.

Write an explicit formula for a_na n , the n^{\text{th}}n th term of the sequence 6, 12, 18, '
Here , we need to find a formula for nth term of the sequence 6 , 12 , 18 , .....
Now , here if you notice carefully ,then you can notice that 12 - 6 = 6 and 18 - 12 = 6 , So the given sequence is an AP ( Arithmetic Progression ) with common difference being 6 , first term being 6 , so now as we know that :
[tex]{\boxed{\bf{a_{n}=a+(n-1)d}}}[/tex]
Where , [tex]\bf a_n[/tex] is nth term of AP , [tex]\bf a[/tex] being first term while [tex]\bf d[/tex] is the common difference . So , now putting the values in above formula ;
[tex]{:\implies \quad \sf a_{n}=6+(n-1)6}[/tex]

Cancelling 6 will yield :

The town of Sickville, with a population of 2603 is exposed to the Blue Moon Virus, against which there is no immunity. The number of people infected when the virus is detected is 95. Suppose the number of infections grows logistically, with k=0.59
Using the logistic equation, it is found that the number of people infected after t days is given by:
[tex]P(t) = \frac{2603}{1 + 26.4e^{-0.59t}}[/tex]
What is the logistic equation?It is given by:
[tex]P(t) = \frac{K}{1 + Ae^{-kt}}[/tex]
[tex]A = \frac{K - P(0)}{P(0)}[/tex]
In which:
K is the carrying capacity.P(0) is the initial amount.k is the rate.In this problem, the parameters are as follows: K = 2603, P(0) = 95, k = 0.59.
Hence:
[tex]A = \frac{K - P(0)}{P(0)} = \frac{2603 - 95}{95} = 26.4[/tex]
Then:
[tex]P(t) = \frac{K}{1 + Ae^{-kt}}[/tex]

Question :-
Find the Area of Rectangle whose Length is 12 cm and the Breadth is 10 cm .44 cm²120 cm²1440 cm²1200 cm²Answer :-
Area of Rectangle is 120 cm² .Explanation :-
As per the provided information in the given question, we have been given that Lenght of the Rectangle is 12 cm and Breadth of the Rectangle is given 10 cm . And, we have been asked to calculate the Area of Rectangle .
For calculating the Area of Rectangle , we will use the Formula :-
[tex] \bigstar \: \: \boxed{ \sf{ \: Area \: of \: Rectangle \: = \: Length \: \times \: Breadth \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf {Area \: of \: Rectangle \: = \: Length \: \times \: Breadth} [/tex]
[tex] \longmapsto \: \: \sf {Area \: of \: Rectangle \: = \: 12 \: \times \: 10} [/tex]
[tex] \longmapsto \: \: \textbf {\textsf {Area \: of \: Rectangle \: = \: 120 \: cm² }} [/tex]
[tex] \underline {\rule {190pt} {4pt}} [/tex]
The area of the given rectangle.
Solution:[tex]area = length \times width[/tex]
[tex]a = 12 \times 10[/tex]
[tex]a = 120 \: {cm}^{2} [/tex]
Therefore, the area of the given rectangle is 120 square centimeters.

Find the Area of the figure below, composed of a rectangle and a semicircle. The radius of the circle is shown. Round to the nearest tenths place.
By dividing the figure in a rectangle and a circle, we will see that the area of the composited figure is equal to 149.25 square units.
How to find the area of the image?The area will be the area of the rectangle plus the area of the semicircle.
We can see that the width of the rectangle is equal to the diameter of the semicircle, and the radius of the semicircle is 5 units, so its diameter is:
2*5 = 10 units.
Then the rectangle measures 11 units by 10 units, then its area is:
A = 10*11 = 110 square units.
In another hand, for a semicircle of radius R the area is:
A = 0.5*3.14*R^2
In this case we have R = 5, replacing that we get:
A = 0.5*3.14*5^2 = 39.25 square units.
Adding these two we get:
Area = 110 square units + 39.25 square units = 149.25 square units.

Step-by-step explanation:
the total surface area is the sum of the individual areas.
we have the ground area : a 6×6 square. = 36 cm²
and we have 4 equal triangles.
the area of a triangle is baseline × height / 2.
which is for each of these triangles
6 × 12 / 2 = 3 × 12 = 36 cm²
so, the total surface area of the pyramid is
36 + 4×36 = 5×36 = 180 cm²
Solution:
We know that:
Surface area of square pyramid = Sum of the area of the faces.This means that:
Surface area of square pyramid = Area of square + 4(Area of triangle)First, let's find the area of the triangle and square. Then, substitute them in the surface area equation to find the surface area of the pyramid.
Finding the area of a triangle:
1/2 x 12 x 6=> 6 x 6=> 36 cm²Finding the area of a square:
6 x 6=> 36 cm²Finding the surface area of the pyramid:
Surface area of square pyramid = Area of square + 4(Area of triangle)Surface area of square pyramid = 36 + 4(36)=> 36 + 144=> 180 cm²6.) The volume of a sphere is two-thirds the volume of a cylinder with the same radius r and height of 2r.

a = b + cid
a = b/(c - d)
a = (d - c)/b
Answer:
a = (d - c) / b
Step-by-step explanation:
ab + c = d
ab = d - c ( divide both sides by b to get the formula for a)
a = (d - c) / b
Last season Steven missed 24% of the free throws in his basketball games. In the two first games this season he got to shoot 25 free throws. If his missed free throw percentage holds from last season, about how many free throws did Steven miss during these two games?
Given:
Last season Steven missed 24% of the free throws in his basketball games.
Free throws in the first two games of this season = 25
His missed free throw percentage holds from last season.
To find:
The number of throws Steven miss during these two games.
Solution:
His missed free throw percentage for this season = His missed free throw percentage of last season = 24%
Free throws in the first two games of this season = 25
So, the number of throws Steven miss during these two games is
[tex]24\%\text{ of }25=\dfrac{24}{100}\times 25[/tex]
[tex]24\%\text{ of }25=\dfrac{24}{4}[/tex]
[tex]24\%\text{ of }25=6[/tex]
Therefore, Steven miss 6 free throws during these two games.

Predict what the graph of the following quadratic function will look like. (If you have a graphing calculator, you can use it to verify your prediction.)
y = 0.3 x squared minus 5
a.
Upward facing parabola-shaped; y-intercept (5, 0); symmetrical with respect to the y-axis
b.
Downward facing parabola-shaped; y-intercept (0, -5); symmetrical with respect to the y-axis
c.
Upward facing parabola-shaped; y-intercept (0, -5); symmetrical with respect to the y-axis
d.
Downward facing parabola-shaped; y-intercept (5, 0); symmetrical with respect to the y-axis
Answer:
c. Upward facing parabola-shaped; y-intercept (0, -5); symmetrical with respect to the y-axis
Step-by-step explanation:
The positive leading coefficient tells you the graph opens upward. (Eliminates B and D)
The constant -5 tells you the y-intercept is -5. (Eliminates A, which shows an x-intercept, not a y-intercept.)
The function is a vertical translation and scaling of the parent function y=x². There is no translation left or right, so the axis of symmetry remains the y-axis.

The correct description is ...

The angles FGH and FJH are corresponding angles
The measure of angle mFJH is 46,2 degrees
How to determine the measure of FJH?The given parameters are:
mFGH = (6x + 21) and mFJH = (17x - 28),
To calculate the angle FJH, we make use of the following equation
mFGH = mFJH
So, we have:
6x + 21 = 17x - 28
Collect like terms
17x - 6x = 21 + 28
Evaluate
11x = 48
Divide both sides by 11
x = 48/11
Recall that:
mFJH = (17x - 28),
So, we have:
mFJH = 17 * 48/11 - 28
mFJH = 46,2
Hence, the measure of angle mFJH is 46,2 degrees
