A rectangle's width is 6 feet less than its length. Write a quadratic function
that expresses the rectangle's area in terms of its length.
A. A(1)=1²-61
B. A(7)=7w
c. A(1)=12+61
D.A(7)=1-6
Answer:
A. A(l) = l² -6l
Step-by-step explanation:
You want a quadratic function for the area of a rectangle whose width is 6 feet less than its length.
Rectangle areaLet l (ell) represent the length of the rectangle in feet. Then the width will be 6 feet less, or (l -6). The area is the product of length and width:
A = LW
A(l) = l(l -6)
A(l) = l² -6l . . . . . . use the distributive property to eliminate parentheses
find the area of 8in 5in 4in 4in 10in 6in
By decomposing the figure into simpler ones, we conclude that the area of the irregular figure is 108 square inches.
How to find the area of the irregular figure?
Here we have an irregular figure that can be decomposed into 3 simpler figures, these are:
A rectangle of 6 inches by 8 inches (the top one).A rectangle of 10 inches by 4 inches (the one in the middle).A rectangle of 5 inches by 4 inches (the one at the right).Remember that the area of a rectangle is the product between the two dimensions, so the areas of these 3 rectangles are:
a = 6in*8in = 48in^2
a' = 10in*4in = 40in^2
a'' = 5in*4in = 20in^2
Adding these areas we get:
48in^2 + 40in^2 + 20in^2 = 108 in^2

A silversmith combined pure silver that cost $34.48 per ounce with 51 oz of a silver alloy that cost $25.35 per ounce. How many ounces of pure silver were used to make an alloy of silver costing
$28.87.per.ounce?
32 ounces of pure silver were used to make the silver alloy.
Here, we are given that a silversmith combines pure silver that costs $34.48 per ounce with 51 oz of a silver alloy that cost $25.35 per ounce.
Let the amount of pure silver = x oz
Cost of pure silver = $34.48 per ounce
Thus, total cost of pure silver = $34.48x
Similarly, amount of silver alloy = 51 oz
Cost of silver alloy = $25.35 per ounce
Thus, total cost of silver alloy = 25.35 x 51 = $1292.85
Now, the total weight of the new silver allow formed = (x + 51) Oz
and the cost of this new allow = $28.87 per ounce
Thus, the total weight of the new alloy = $28.87 (x + 51)
Hence, we can form the following equation-
$34.48x + $1292.85 = $28.87 (x + 51)
34.48x + 1292.85 = 28.87x + 1472.37
34.48x - 28.87x = 1472.37- 1292.85
5.61x = 179.52
x = 179.52/ 5.61
x= 32
Hence, 32 ounces of pure silver were used to make the silver alloy.

The fraction model below shows the steps that a student performed to find a quotient. Which statement best interprets the quotient?
The statement that best interprets the quotient is "there are 6( 1/4 ) two - third in 4( 1/6 )".
In mathematics, the sum obtained by diluting two numbers is known as a quotient. The term "quotient" is used frequently in mathematics and is sometimes known as the integer portion of a division, a fraction, or a ratio.
Any integer may be used as the larger number in a fraction, which is a number that represents a percentage of the larger number. It is shaped like a denominator and a numerator.
For step 1:
The shaded part is:
4 + 1/6 = 4(1/6) = 25/6
Now, dividing the shaded part by the unshaded part,
( 25/6 ) / ( 2/3 ) = ( 25/6 ) × ( 3/2 )
( 25/6 ) / ( 2/3 ) = 25/4
( 25/6 ) / ( 2/3 ) = 6( 1/4 )

We get that Shannon did not mix the correct shade as the ratios are not equal.
We are given that a particular shade of paint is made by mixing five parts of red paint with seven parts of blue paint.
This means that the ratio of the paints in that shade is
Red : Blue = 5 : 7.
Now, we are also given that to make the correct shade, Shannon makes 12 quarts of blue paint with 8 quarts of red paint.
Here the ratio becomes:
Red : Blue = 8 : 12
= 4 : 6
= 2 : 3
Now, since both the ratios are not equal, he did not mix the correct shade.

If you draw a horizontal line through y = -2, so will see that every point is the same distance from y = -2 but in the opposite direction. For example, Point w is 3 units above y= -2 and w' is three units below y = -2. That is true for every point on original to the image.
A company is designing boxes to ship their product to stores. The design team decides that the width of the box should be five feet shorter than the length, and the height of the box should be three feet longer than the width. Due to shipping constraints, the length of the box can be no greater than six feet.
The volume of the box, V(x), can be modeled by a polynomial function, where x is the length of the box. Which of the following correctly models the situation above and gives the correct domain?
The polynomial function is V(x) = x^3 - 7x^2 + 10x and domain of x is (5,6]
Here we are given that the length of the box is x
Also, the width of the box should be 5 feet shorter than the length
Thus, width = x - 5
and the height should be 3 feet longer than the width
Thus, height = x - 5 + 3
= x - 2
Now the volume of the box = length × width × height
Volume = x (x-5) (x-2)
V(x) = (x^2 - 5x) (x-2)
V(x) = x^3 - 2x^2 - 5x^2 + 10x
V(x) = x^3 - 7x^2 + 10x
Now, looking at the options, we see that option C is eliminated.
Now, let us look at the domain of x
Since width cannot be negative (x-5) > 0
⇒ x > 5
Now in option A domain is (0, 6], but x cannot take values from (0,5). Thus, option A is eliminated.
Similarly, we can eliminate option B also since x cannot take values from (0, 2)
Thus, option 4 is the correct answer.

As per the question statement, we are given that a diagram which shows the position of town A and the scale of 1 cm representing 10 km.
Town B is 64 km from town A on a bearing of 070°. We are supposed to tell the position of town B.
Let's assume that town A lies at origin in cartesian plane and as 1 cm represents 10 km therefore,
[tex]1cm = 10 km\\1 km = 0.1 cm\\64 km = 64*0.1=6.4 cm[/tex]

Answer:
True
Step-by-step explanation:
We use definitions to help us in this problem. The definition of an integer is a whole number that is not a fraction or has any fractional value. This definition includes all whole numbers, so we know that all whole numbers can be classified as integers. That's one condition done. The definition of a rational number is a number that can be written as a fraction. All whole numbers can be written as a fraction (i.e. 12/1, -3/1, 10000/1).

b) Find the total value of the gasoline in the filled tank.
In linear equation, the total value of the gasoline in the filled tank = $65605290
What is a formula for linear equations?
A linear equation has the slope-intercept form y = mx + b. Variables in the equation are x and y. When x is 0, the integers m and b provide the line's slope (m) and the value of y. (b). Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.

You may recall that the area of a rectangle is A=L⋅W, where W is the width and L is the length.
Suppose that the length of a rectangle is 4 times the width. If the area is 900 square feet, then what is the width of the rectangle, in feet?
Answer:
Width = 15 ft
Step-by-step explanation:
Given formula,
→ A = L × W
Let us assume that,
→ Length = 4x
→ Width = x
→ Area = 900 ft²
Then the value of width will be,
→ A = L × W
→ 900 = 4x × x
→ 4x² = 900
→ x² = 900/4
→ x = √225
→ [ x = 15 ft ]
Hence, the value of width is 15 ft.
